Study on the requirement of organic primer for titanium dioxide in the plastics industry

Posted on by adminLeave a comment
Titanium dioxide,as a kind of high-quality white pigment filler, has a wide range of USES, such as plastic profile, color masterbatch, paint, emulsion paint, powder paint, paper making, chemical fiber and cosmetics, etc. It should be used for both the water system and the solvent system and the solvent-free system. There are additional requirements for selecting organic coating agents due to the different applications and application systems, and there are significant differences. Simple use of traditional TMP or peg can no longer meet the requirements and has some adverse effects, such as the bubble problem. According to the different USES of titanium dioxide, various organic treating agents should be used to treat the titanium dioxide to achieve a satisfactory treatment effect in the application. Different USES of titanium dioxide, titanium dioxide application processing performance requirements are also other.
Requirements for titanium dioxide for plastics
1. High viscosity dispersion/extrusion lubrication
To improve the strength of plastic products and reduce the cost, plastic products in the color filler added more and more, the proportion of resin is smaller and smaller, the compatibility and lubricity of each component are more and more difficult, easy to lead to the surface of plastic products rough and color uneven. Take the color masterbatch commonly used in the plastic industry as an example: the color masterbatch is generally made by extrusion and granulation of titanium dioxide powder after kneaded at high temperature using organic resin with a low density such as high-pressure polyethylene or polyethylene wax as the carrier. To produce a high concentration of white masterbatch and avoid low resin compatibility during the application, it is required to use as little carrier resin as possible to moisten as much titanium dioxide as possible. Therefore, titanium dioxide used in the production of masterbatches must have excellent surface wettability and lubrication properties. Otherwise, it will be challenging to granulate, challenging to disperse or distribute unevenly in use.

2. Temperature/weather resistance
The vast majority of plastic products, no matter what kind of resin, no matter what processing method, need to be in the high-temperature melt state with titanium dioxide and other additives before processing and forming. The processing temperature of plastic products is around 200 degrees (or even higher). If some components decompose at this temperature, pigment migration and porosity will be caused, seriously affecting plastic products’ surface quality and physical strength. Therefore, the temperature resistance of each component in the formula must be excellent. Besides, for most plastic products (such as plastic film, plastic electrical appliances) used in an outdoor or healthy light environment, UV resistance must also be considered. In the processing of PVC plastic products, a lead stabilizer is usually added. This kind of stabilizer is easy to react with other active chemical materials at high temperatures and produce black substances, which is the “lead black” problem in plastic processing. Therefore, the organic coating agent on the titanium dioxide surface must be entirely inert for the lead stabilizer.

3. Dry powder fluidity/moisture resistance
More and more factories use continuous production line in plastic products, related raw materials (such as resins, fillers, pigments) will also use transmission belt or vibration leakage sieve equipment to continuously automatic metering. Suppose the flow of titanium dioxide dry powder is not good. In that case, it will be stuck in the transmission belt or plug the screen hole, resulting in titanium dioxide that can not be accurately measured and smoothly added, thus affecting the quality of plastic products.

The Property And Application of Zinc Sulfide

Posted on by adminLeave a comment

What property does zinc sulfide have?

Zinc sulfide This inorganic compound has a chemical composition of ZnS. It appears as a white, off-white, or light yellow powder. Zinc Sulfide is stable when in dry air. When in humid air over a period of time or with moisture, it gradually oxidizes to zinc sulfate. It is insoluble when mixed with water and soluble when mixed with acid.
Zinc Sulfide is usually obtained through the reaction of hydrogen sulfide with zinc salt solutions. When a small quantity of Cu,Mn,Ag is added to the crystal ZnS as an activater, it will emit different colors after illumination.

What are the applications of zinc sulfide?

The zinc sulfide compound semiconductors are important because they have outstanding physical characteristics, including a large band gap, high refractive indices and high light transmissibility in the visible spectrum. They also offer great potential for optics, electronic and optoelectronic applications.

Zinc Sulfide exhibits excellent electroluminescence and fluorescence effects. Nano-zinc has a unique effect. It has excellent properties in the areas of magnetism (electricity), optics, mechanics, and catalysis. It is for this reason that research into nano-zinc-sulfide caused a lot of controversy. In 1994 Bhargava reported on the surface passivation properties of nano ZnS:Mn-phosphor, which not only had an external quantum efficiencies of up to 18% at high temperatures but also a fluorescence life of five orders of magnitude shorter. The performance of ZnS has improved dramatically, opening up new possibilities for its use in materials.

Zinc Sulfide: Used as an analytical reagent for paint, paint manufacturing, white and opaque glasses, filling of rubber and plastic, and to prepare phosphor.

An Iron Copper Alloy Provides Conductivity, Toughness, and Strength

Posted on by adminLeave a comment

An iron copper alloy provides conductivity, toughness, and strength. It can be adjusted to fit specific applications.

The microstructural and mechanical properties of grey cast iron with different concentrations of copper have been examined. The addition of copper increases the hardening and strengthening of the alloy, but at a high copper content it results in a brittle white iron structure due to the precipitation of ledeburite. The tensile strength and impact strength increase with increasing copper content, while the ductility decreases.

Currently, most of the copper used for electrical purposes has about 6% iron added to it to provide strength and wear resistance. But, there is a desire to have even more iron in these alloys for improved conductivity and other special properties.

Iron-copper master alloys can be made by sintering pure elemental copper powders with a range of iron compositions. These alloys are then infiltrated into iron-base powder metallurgy (P/M) parts to produce a variety of strengths and densities. The properties of the infiltrated parts are greatly influenced by the type and composition of the iron powder, infiltrant composition and furnace conditions, as well as any heat treatment that may be performed after the infiltration process. Carbon-free iron-copper P/M parts exhibit very good strength with only a minor reduction in ductility, but the performance of carbon-containing iron-copper P/M parts improves greatly after heat treatment. The improved ductility is accompanied by excellent strength levels, which are greater than that achieved in pre-sintered iron-copper premixes without carbon.

Lithium Chloride

Posted on by adminLeave a comment

Lithium chloride (LiCl) is an ionic compound. It has a lewis structure. Ionic compounds are formed when two atoms of the same element bond with each other through the transfer of electrons. In chemical bonding, atoms try to attain a full set of eight electrons in their valence shell (also known as the noble gas configuration). Atoms achieve this by sharing their valence electrons with other atoms through covalent bonding or by donating them to nonmetal atoms, through ionic bonding.

Lithium is a Block S, Group 1, Period 2 metal with an atomic number of 3. It has one electron in its valence shell (2s1) and has the lowest nonmetallic character among the alkali metals. Its high valence electron affinity and low electronegativity make it very reactive with other atoms, resulting in the formation of ionic compounds.

When a lithium salt is heated, the electrons absorb heat energy and jump to a higher energy level. When they return to their lower energy states, they release the photons of light we see. These emitted photons form an emission spectrum, allowing us to identify the specific salt. Different metallic atoms have unique electronic configurations, which create the different color spectral lines observed in flame tests.

Properties and Applications of Boron Carbide

Posted on by adminLeave a comment

The boron-carbide crystal is rhombohedral in structure. Its crystal lattice is the D3d5R3m space lattice. The rhombohedral lattice can be described as an icosahedron-shaped primitive cell grid that extends diagonally in the space. The c-axis is the same as the diagonal of the area. A linear chain is formed by connecting three boron-atoms to an adjacent icosahedron. Three of the 12 icosahedral position are found on the chain. If B is due to the icosahedron’s position and C is in a chain, the stoichiometry is B4C.

1. Basic properties and applications for boron carbide

1) Low density

B4C density is small at 2.52g/cm3. The empirical formula (9) can be used to express the relationship between carbon content and density in the homogeneous area.

r=2.4224+0.00489C%(9)

Because of the low density of the boron carbide, if a higher density is achieved, the performance of the boron carbide can be reached, with high strength and hardness. Save energy.

Hardness and wear resistant

B4C exhibits super hardness, and it is highly resistant to wear. In the homogeneous area, B4C’s Vickers Hardness increases as the C content increases. The hardness is 29.1 GPa when the carbon is 10.6%; at 20% carbon, it can reach 37.7 GPa. At high temperature, its hardness remains high (>30GPa). You can express the change of hardness in temperature by using empirical formula (10).

H=H0-exp(-aT)(10)

The formula is: H0-the hardness of the material at room temperature

Temperature is T.

Carbon is referred to as a constant.


This formula applies to 201700. B4C is second only to cubic BN and diamond in terms of hardness.


B4C wear resistance increases with temperature. As the temperature increases, the friction coefficient of B4C decreases. It drops to 0.05 between 20 and 1400, while the friction rate also decreases. B4C’s super hardness and friction properties have made it a popular sandblasting tool.

Silicon nitride resists chemical corrosion with amazing strength. It can resist almost all inorganic acid solutions, caustic soda below 30% and many organic acids. It’s also a highly-performance electrical insulation material.

Ceramics made of silicon nitride have many excellent properties. They are used for bearings as well as turbine blades.

Silicon Nitride as a Refractory Material

The excellent high temperature properties of silicon nitride are said to make it a promising material for high temperature structural materials. These include high high-temperature strengths, corrosion resistance and good wear resistance.

(1) Application to ironmaking refractories
Recent years have seen significant improvements in the corundum-silicon-carbide-silicon-nitride products used for large-scale blast-furnaces. In the middle section and load-bearing part of coke kilns, large blast furnaces are commonly made from silicon nitride refractory, silicon carbide or silicon oxynitride refractory.

2) Application in steelmaking Refractories
The bottom ladle material has been made of silicon nitride in recent years. The addition of silicon-nitride materials to the slideplate improves the wear and erosion resistance of the slideplate, as well as its service life. It also reduces the price of steel per ton for ladle refinement.

(3) Application to refractory smelting non-ferrous metals, such as copper, aluminum, zinc, etc.
Silicon nitride does not wet metal solutions at high temperature, so it is suitable for high-temperature products in the nonferrous metal smelting processes, such as thermowells. Smelting furnace linings. Container linings. Crucibles. Silicon nitride ceramic products have good thermal shock resistance and can be used stably for a long time at high temperatures or in high-temperature-low-temperature cycles.

The aluminum powder has lightweight, high buoyancy, strong hiding power

Posted on by adminLeave a comment
What is aluminium powder? Aluminum powder (also known as silver powder) is a metallic pigment that’s silver in color. It is produced by adding powder to aluminum foil and crushing it into a powdery scaly texture. Aluminum powder is light, buoyant, concealing, heat-reflective, and has high hiding power. Aluminum powder is also available in non-floating form after treatment. Aluminum powder can identify fingerprints, and it can also be used in fireworks. Aluminum powder is a type of metallic pigment due to the wide range of applications, high demand, as well as its variety.

What is the purpose of aluminum powder?
The particles of aluminum powder used in the pigments are scaly. The scaly particles are what give the aluminum powder a metallic colour and shielding effect. Metal aluminum powder is produced industrially since a very long time. Ramming was the early production method. The aluminum crumbs was placed in the groove of punching machine. The machine drove a ramming hammer to continuously punch aluminum crumbs into the groove. The ductile metal gradually shatters and becomes flakes. The aluminum is then screened to remove the powder that is suitable for the product. The ramming technique has a low production efficiency, and it is hard to control the quality of the products. There is also a lot dust, which can easily catch fire or explode, in the process.
German Hamtag began producing aluminum powder using a mill in 1894. Steel balls, scrap aluminum and lubricants went into the ballmill, where the scrap aluminum was crushed by the steel balls. This resulted in scaly aluminium powder that filled the ballmill and pipeline with inertness. The method of “dry production” is still being used for gas. J. Hall in the United States developed the method of adding petroleum solvents to the ballmill to replace the inert air. The produced aluminum powder is then mixed with this solvent to create a thick slurry that can be used to make slurry aluminum paint. This method has been widely adopted because it is safe and easy to use. The “wet method” is the method used by most modern aluminum powders. Aluminum powder can also be used for the manufacture of fireworks and explosives. Certain types of electronic devices are also made from it. A lot of paints and sealing agents contain aluminum powder.

Is Aluminum Powder Dangerous?
Exposure to fine particles can lead a fibrosis of the lungs. This is accompanied with coughing and shortness in breath. Aluminum powder can be a fire-hazard because it is flammable.
The powder coating carries a lower risk of fire than regular paint. Comparing powder/air to solvent/air, the ignition energy is 50-100 more. All flammable powders or dusts will, however, form an explosive mix with air. This can be a dangerous situation. Transport, storage, and processing are all safe if the appropriate measures are taken beforehand. To ensure safety, the powder concentrations for the powders listed above must not exceed 10g/m3. In the spray zone, this concentration often exceeds 10g/m3. There is always enough oxygen in the air, so it is essential to avoid sparks with more energy.

Comparing resin powders without pigments, the dust constant (a measure of explosive force) and maximum pressure explosion increase by 10% when aluminum powder is included at 5-6%. As the amount of aluminum powder increases, so will the explosive power. Aluminum powder with a content greater than 25 percent will have the same explosive power as pure metal powder. This dependency on aluminum powder pigments is not responsible for the lowest initiation energy. Pure resin powder will not reach the initiation energies, no matter what dispersion technique is used. Aluminum powder with a pigment content > 10%, fine particles and uncoated aluminium powder can reduce the ignition energy.

Aluminum-containing powder coated coatings are identical to pigmented powder coated coatings. Fire or explosion is not a problem as long they don’t exceed the specified limit.
Aluminum powder must not be separated, accumulated or concentrated in the factory to ensure the safety of spraying. These requirements are also applicable to solvent-based paints containing gold and copper powder. The explosion risk directly caused by the copper-zinc powder alloy is lower than that of aluminum.
Aluminium powder characteristics
The aluminum powder suitable for the pigment is the one whose particles have the shape of scales. Its surface has been treated and it is suitable for using as a pigment. Aluminum powder paste consists of pigment aluminum and solvent. Its characteristics and use are similar to those of aluminum powder. The output and dosage is larger because it’s easy to use. Comparing to other pigments, the aluminum powder for paints has more features in these aspects:
1. Scaly coverings have certain characteristics.
The particles of aluminum powder are scaly and have a diameter-to-thickness ratio between (40:1) and (100:1). Aluminum powder dispersed on the carrier has the characteristic to be parallel to the substrate. Numerous aluminum particles are connected. The particles are filled together to form a continuous metallic film that covers the surface and reflects light from outside. The uniqueness of aluminum powder lies in its ability to hide. The surface area of the aluminum powder is a function of the diameter-to-thickness ratio. Aluminum is stretched during the grinding process, the diameter-to-thickness ratio continues to increase, and the hiding power also increases.
2. Aluminum powder has shielding characteristics
This continuous layer of aluminum powder is formed by multiple layers of aluminum powder in parallel in the carrier. The spacing between the layers of aluminum powder prevents the capillary pores in the carrier film from allowing moisture or gas to pass through. This is due to the physical shielding properties of aluminum powder.
3. Aluminium powder’s optical properties
The aluminum powder is made from aluminum that has a metallic luster and a light colour. Its smooth surface can reflect between 60% and 90% of visible, ultraviolet and infrared lights. The surface of the object is silvery, bright, and coated with paint that contains aluminum powder. Aluminum powder is known for its ability to reflect light.
4. Aluminum powder can produce a two-color effect
Aluminum powder exhibits a metallic luster, and is parallel to the coated item. The gloss and color depth change depending on the incident angle and viewing angles of the incident light in the carrier that contains transparent pigments. This is called “the two-color effect”. Aluminum powder is placed in layers in the coating. When light strikes each layer of aluminum flake, the film thickness is affected by the light differently. Also, the brightness of the reflected light varies. As light passes into the film that contains transparent pigments, it is colored by the pigment and then reflected back to the viewer at different levels. This results in changes of color tone, metallic light, and viewing angle. Aluminum powders with this property are widely used to create metallic or hammer paint.
5. Aluminium powder with floating properties
The large floating type of aluminum pigments and aluminum powder is characterized as scaly floating over the surface of coating film.

This 3D printed electric motorcycle is fully functional and made with aluminum powder
Airbus has entered the 3D motorcycle market. Light Rider, a 3D printed electric bicycle, is the future for electric cars and 3D printed vehicles.
This 3D bike was launched by APWorks, a subsidiary of Airbus, and was described by them as “corrosion-resistant, combined with lightweight aluminum and almost specific strength titanium.” Scalmalloy – a special alloy for APWorks – is responsible for these qualities. Aluminum powder developed by researchers.
How do you print something so strong as a bicycle using powder? Airbus has explained that Light Rider is made of thousands thin layers with a thickness of 60 microns. Hollow frame adds to the appeal of this 3D printed electric bike. Comparing to other bicycles the total frame weight has been reduced by 30%. Joachim Zettler – CEO Airbus APWorks GmbH – explained that this bicycle cannot be made using traditional milling or welding techniques. The team decided on a hollow, branched structure. So, now each Light Rider 3D printed weighs less than 35kg.
Light Rider may seem like a toy but it is incredibly practical. The top speed of the Light Rider is 49m/h, despite not being Harley. The company’s aim is to use 3D Printed electric bicycles mostly for urban driving. Airbus claims the battery of its electric vehicle can travel 37 miles after each charge.
