Six Uses Of Precipitated Barium Sulfate in The Industrial Field

Electronic Ink Barium Sulfate of Yunfu Hongzhi New Materials Co., Ltd., represented by the CB series, is widely used in PCB ink. As a functional filler, it has small particle size, inorganic coating on the surface of the product, good dispersion and other characteristics. The printability, coverage, leveling, and anti-sagging of the circuit board solder mask ink have been significantly improved. Electronic Ink Barium Sulfate has stable resistance to tinning and boiling whitening, and can also reduce the linear expansion rate of ink without affecting the curing efficiency. In addition, it has excellent resistance to cold and hot shocks, high temperature storage and acid resistance, greatly extending the service life and reliability of PCB circuit boards.

Ultra White Barium Sulfate of Yunfu Hongzhi New Materials Co., Ltd., represented by the M series, is widely used in coatings. The product has high whiteness, low oil absorption, good dispersibility, and can increase the gloss and color rendering of paints. At the same time, our Ultra White Barium Sulfate has high chemical stability, which can improve the weather resistance, corrosion resistance and UV resistance of the coating. Due to the low oil absorption of Ultra White Barium Sulfate, the coating can still maintain good fluidity even at high concentrations. Ultra White Barium Sulfate is added to the coating to increase the solid content and reduce volatile organic compounds (VOCs). Ultra White Barium Sulfate is easily dispersed in coatings and inks, and can be stored for a long time while maintaining quality stability. Among various types of coatings, Ultra White Barium Sulfate plays an important role in improving the overall quality of coatings.

High Gloss Barium Sulfate of Yunfu Hongzhi New Materials Co., Ltd., represented by the F series, is widely used in plastics. It can improve the impact and rigidity of plastics, reduce shrinkage, improve dimensional stability, and enhance the wear resistance and corrosion resistance of plastics. High Gloss Barium Sulfate has a small particle size and high whiteness, which can improve the appearance color of plastics, making the plastics glossier, brighter and more beautiful. It also has good dispersibility and can be evenly distributed in plastics, improving the processability and mechanical properties of plastics. High Gloss Barium Sulfate is acid-resistant and alkali-resistant, and will not react with brominated flame retardants. Adding it to brominated flame-retardant plastics can reduce the precipitation of additives and does not affect the flame retardant effect of the formula. In addition, High Gloss Barium Sulfate can effectively reduce the cost of plastics and is a cost-effective plastic additive.

The PET Plastic Barium Sulfate of Yunfu Hongzhi New Materials Co., Ltd., represented by the AB series, has important applications in polyester film (BoPET). Since the refractive index of PET Plastic Barium Sulfate is almost the same as that of PET, it does not affect the transparency of the film. Adding PET Plastic Barium Sulfate can reduce the shrinkage rate of the product, improve the temperature resistance, and improve the crystallinity of the film. Compared with silica, it can reduce the haze of the PET film. PET Plastic Barium Sulfate can increase the surface roughness, improve the opening performance of the film, and play an anti-slip and anti-adhesion role. PET Plastic Barium Sulfate has excellent dispersibility after special surface treatment, and has little effect on the filtering pressure during processing and extrusion. It can also improve the whiteness and glossiness of BoPET, making the film look more beautiful. Good dispersibility ensures the uniform distribution of PET Plastic Barium Sulfate in BoPET, and improves the physical properties of the film such as strength and wear resistance. In addition, it can also improve the barrier performance and UV resistance of BoPET, and extend its service life, which plays an important role in the production and application of BoPET.

High Purity Barium Sulfate of Yunfu Hongzhi New Materials Co., Ltd., represented by the H series, plays an important role in lithium-ion battery separators and can be used as a ceramic coating agent for separators. On the one hand, it can significantly enhance the mechanical properties of the separator, making it less likely to break when subjected to external extrusion, impact, etc., providing reliable physical protection for the battery and greatly improving the safety of the battery. On the other hand, High Purity Barium Sulfate has good thermal stability, which can effectively improve the heat resistance of the separator. When heat is generated during the battery charging and discharging process, it can prevent the separator from shrinking, deforming or even melting due to high temperature, reducing the risk of thermal runaway. In addition, High Purity Barium Sulfate can also adjust the pore structure of the separator to ensure smooth transmission of lithium ions, while preventing direct contact between the positive and negative electrodes, providing a strong guarantee for the efficient and safe operation of lithium-ion batteries.

High Purity Barium Sulfate of Yunfu Hongzhi New Materials Co., Ltd., represented by the H series, has important applications in lead-acid batteries. High Purity Barium Sulfate is added to the negative plate of the lead-acid battery as a negative electrode additive. Because it has a crystal structure similar to that of the active material after discharge, it becomes the crystal nucleus of PbSO4 deposition, which reduces the supersaturation of PbSO4 during crystallization and prevents the shrinkage of the negative active material. High Purity Barium Sulfate is an inert substance with both chemical and electrochemical stability. It can exist stably and for a long time in the negative active material and exert its effectiveness for a long time. The "nucleation" and "isolation" effects of High Purity Barium Sulfate exist for a long time, making it difficult for Pb particles and PbSO4 particles to merge, and maintaining a developed specific surface area of ​​the negative plate. High Purity Barium Sulfate can also improve the capacity and cycle performance of the battery, reduce the internal resistance and self-discharge rate, and enhance the reliability and safety of the battery.
