Polyvinyl chloride, short for PVC. It is a white powder, belongs to thermoplastic resin. PVC used to be the most common plastic in the world, and it was widely used. According to the different application, PVC can be divided into three types: universal PVC resin, high degree of polymerization PVC resin, cross-linked PVC resin. According to the method of gaining vinyl chloride monomer, PVC can be divided into calcium carbide method, ethylene method and imported (EDC, VCM) monomer method. According to polymerization methods, PVC can be divided into four categories: suspension PVC, lotion PVC, bulk PVC and solution PVC. According to the content of plasticizer, PVC plastics are often divided into how many types? do you know that?
The price of talcum powder is affected by many factors. Different specifications, different quality levels, and different applications, all determine the price differences. The selling price of talcum powder is between 500-2500yuan, of course, it has lower and higher prices, this price is only for reference.
The main component of talcum is magnesium silicate containing water, and talc belongs to monoclinic system. The grade of talcum powder can be divided into five types: Industry grade, Cosmetic grade, Ceramic grade, Medicinal and edible grade, Paper-Making grade.
TiO2 nanoparticles exhibit more cellular toxicity in anatase due to increased amount of intracellular reactive oxygen species (ROS). The nano bio interfacial interaction of anatase TiO2-NPs with EPS of algae showed higher algal toxicity than that of rutile TiO2-NPs.
TiO2 nanoparticles have wide applications in industry; some of them are given in cosmestics, dye,paper,plastic and rubber industry,food additive, construction material, coating to building, pigment, medical devices, sunscreens, gas sensing. TiO2 nanoparticles in reducing toxicity of dyes and pharmaceutical drugs also play a role.
Living systems are involved in the production of nanoparticles which are more stable as compared with chemically synthesized nanoparticles. Nanoparticles synthesized using microorganisms are found to have less aggregation behavior due to presence of more repulsive forces. Utility of nanoparticles is mainly dependent upon its size, shape as well as stability.
Nanoparticles have wide applications in various fields due to their small size. Titanium dioxide nanoparticles are bright with high refractive index (n = 2.4) which makes them suitable for industry. Biosynthesis of titanium dioxide nanoparticles has gained wide interest among researchers due to its cost effective, eco-friendly and reproducible approach.
BEIJING — In a significant easing of Covid controls, the Chinese government said Wednesday that people will no longer need to show negative virus tests or health codes in order to travel between different parts of the country. As more regions ease COVID control measures, the hospitality, tourism and transportation industries are expected to take baby steps toward recovery.
