Q:What's the use of wollastonite powder in coatings?How do you use it?
Also found in certain deep metamorphic rocks: used as raw materials or fillers for paper making, ceramics, cement, rubber, plastics, gas filtration materials and heat insulation materials, metallurgical fluxes, etc.
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:Silica powder and calcite powder have big difference
. Wollastonite is widely used in the fields of ceramics, chemical industry, metallurgy, paper making, plastics, coating and so on.
Q:How does the result of wollastonite analysis convert the grade of ore-forming stone?
In S, the P content is not high, it can be a rough calculation, the amount of CO2 loss CaCO3 as part of all high temperature decomposition of CO2, according to the measured amount of CaO accounting for the amount of calcite and calcite, and the test results of CaO minus the amount of calcite in the level of CaO, the result is wollastonite in the amount of CaO, according to the results and the atomic weight of anti launched wollastonite amount. This calculation in the case of low S.P content. The error and the analysis results with the X-RD almost.
Q:The difference between silica powder and wollastonite powder
Quartz sand is quartz quartz stone crushing processing. Quartz stone (quartz rock) also known as silica, silicate minerals is a hard texture, abrasion resistance, stable chemical properties. There are mainly quartz sandstone, quartzite and quartz in nature. Quartz sandstone is the consolidation of clastic rock, clastic quartz content more than 95%.Summarize yourself
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:Chemical TSP and wollastonite filled nylon do contrast to the good toughness
Cleaning and coated with anti - reflective film lenses, such as cameras, slide projectors, microscopes lens, can be used about 20% of alcohol preparation cleaning agent for cleaning. When cleaning application soft brush or cotton with a small amount of cleaning agent, from the lens center outward circular motion. Do not put this kind of lens soaked in cleaning agent cleaning; cleaning the lens shall not force wipe, otherwise it will scratch the antireflection film, lens damage.
Q:The difference between wollastonite and quartzite
Wollastonite is a chain metasilicate, and is a kind of fiber like needle. Because of its special crystal morphology, crystalline structure determines its properties. Wollastonite has good insulation, high whiteness, good dielectric properties and high heat resistance and weather resistance. Wollastonite is widely used in the fields of ceramics, chemical industry, metallurgy, paper making, plastics, coating and so on..
Q:Salt bath and bath salt is what?
Mineral salt is a salt, which contains many minerals, these minerals beneficial to human health, easy to absorb, containing silicate (SiO4) generic minerals (including silicon containing salt, other such as partial Portland, wollastonite CaSiO3 case). Can be regarded as a combination of SiO2 with other oxides (mostly metal oxides).
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.
