Q:What are the surface modification methods and processes of wollastonite?
The treatment of wollastonite with silane coupling agent by surfactant modification can greatly improve its compatibility with polymer and enhance the filling effect, but the production cost of silane coupling agent modified is higher. Therefore, in some applications, the available surface active agent is cheaper, such as stearic acid (salt), quaternary ammonium salt, polyethylene glycol, fatty alcohol polyoxyethylene ether (nonionic surfactant) on surface modification of wollastonite powder. These surfactants are coated on the surface of particles by polar groups and particles, which can greatly enhance the lipophilic properties of wollastonite fillers... Details can be seen on the powder technology.
Q:Really useful stone powder and jade powder processing of jade? Do you glue it straight together or do you press it directly?
Yes, but they are not called jade articles, but they are called finished products, and the processing is usually pressed directly
Q:The function of wollastonite powder
Wollastonite after finishing has the characteristics of high aspect ratio (10:1-15:1), high whiteness and so on. Has been widely used in plastics, rubber, coatings, ceramics, friction materials, insulation materials, building materials and other industries.
Q:Latex paint, wollastonite powder can replace all heavy calcium carbonate?
Shuangfei powder is actually a "big white", if the brush on the wall, the surface cannot do other processing (putty, paint, etc.) must take this shovel back Shuangfei powder putty, can brush paint, otherwise, in this layer directly Shuangfei powder paint brush will peel a piece off. I have this lesson, I hope you will not be fooled again, repeat my mistakes.
Q:Can titanium, barium sulfate, calcium carbonate, wollastonite powder and talcum powder be transported by ordinary vehicles?
Occupational protection is recommended from the above quality, grade, comfort, economy to assess, choose a good mask to prevent pneumoconiosis.At present, China has KN100 grade products, and the use of comprehensive costs of about one yuan per day.
Q:The difference between wollastonite and quartzite
Quartz sand is quartz quartz stone crushing processed. Rock (quartz), also known as silica, is a hard, abrasion resistant and chemically stable silicate mineral. In nature, quartz sandstone, quartzite and quartz quartz exist. Quartz sandstone is a consolidated clastic rock with a quartz content of more than 95%.
Q:What is the difference between wollastonite powder and calcium carbonate?
The composition of wollastonite is Ca3 [Si3O9]. Three orthorhombic system, belongs to single chain silicate mineral. Usually flaky or radially or fibrous aggregates. White microstrip gray. Glass luster, pearl luster on cleavage surface.
Q:Addition of needle like wollastonite in engineering plastics
Wollastonite is added to engineering plastics, which is called calcium plastic in the industry, because slaked lime is calcium hydroxide and lime is calcium carbonate. In order to increase the strength of the plastics, the calcined wollastonite is added.
Q:Main characteristics of Wollastonite
The chemical formula of wollastonite is CaSiO3, the structural formula is Ca3[Si3O9], and the theoretical chemical components are CaO 48.25% and SiO2 51.75%. In nature, pure wollastonite is rare, and in its formation, Ca is sometimes replaced by Fe, Mn, Ti, Sr plasma, and is isomorphous, with a small amount of Al and trace amounts of K and Na.
Q:What are the specific applications of wollastonite in coatings?
The use of needle like wollastonite 7, paint industry, excellent wollastonite powder coating used to paint some products, and some titanium dioxide instead of lithopone import P820 as a filler, can improve the coating leveling. And can greatly reduce the cost of paint;The use of needle like wollastonite 8, metallurgy and refractory industries, wollastonite unique physical characteristics - high melting point, making wollastonite become the most promising foreign experts in refractory materials;The use of needle like wollastonite 9, welding rod industry, wollastonite used in coating electrode, accelerate the melting rate, with energy saving, anti porosity, accelerated coating melting speed and so on;
