- Q: Conglomerate can not be exploited to destroy
- Limestone (Limestone), commonly known as limestone, is a major component of calcite. Limestone is a sedimentary rock. Sometimes contain dolomite, clay mineral and detrital minerals, gray, gray, gray and black, yellow, red, brown red color, hardness is generally small, and the violent reaction of dilute hydrochloric acid. The structure is complex, with two kinds of clastic structure and grain structure. The clastic structure is mainly composed of particles, crystalline matrix and bright crystalline cement. Also known as debris particles, mainly in clastic, bioclastic and oolitic, micritic matrix is composed of calcium carbonate fines or crystal particle mortar, mostly less than 0.05 mm, microspar cements are chemical precipitates filling in porous rock particles in between, is larger in diameter than the calcite crystal particles of 0.01 mm the grain structure is; crystal particles by chemical and biological chemical deposition of.
- 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: 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: What are the surface modification methods and processes of wollastonite?
- Wollastonite commonly used surface modification agent: at present, the wollastonite commonly used surface modification is the main agent of silane coupling agent, titanate and aluminate coupling agent, surface active agent and methyl methacrylate. 1 silane coupling modified silane coupling modification is one of the commonly used surface modification methods of wollastonite powder. The process of dry modification is generally used, and the amount of coupling agent is related to the required coverage and the specific surface area of the powder. Amino silane treatment of wollastonite, wollastonite content is 0.5% of the weight; methacryloyl oxygen containing silane dosage of wollastonite weight 0.75%, these two kinds of modified products were filled with nylon 6 and polyester instead of 30% glass fiber can significantly improve the mechanical properties of the products.
- Q: World resources of Wollastonite
- At present, the application in the high-end market is very optimistic. At present, domestic enterprises have begun to carry out deep processing of wollastonite, synchronous application research, I believe that in the next 2-3 years, there will be a domestic enterprises among the forefront of the world wollastonite industry.
- Q: The function of wollastonite powder
- Wollastonite chemical composition close to the theoretical value, high purity, fine acicular structure, with low loss, harmful components (MnO, Fe203) content is low, the indicators better than similar domestic ore.
- Q: Can wollastonite be certified by REACH?
- Wollastonite does not need to be tested, but pre registration and registration are required.
- Q: What's the use of wollastonite powder in coatings?How do you use it?
- Ca3 Si3O9. Three triclinic. Usually flaky, radial or fibrous aggregates. White grayish. Glass luster, pearl luster. Cleavage surface hardness of 4? 0. parallel cleavage {100}, {001} parallel medium, two groups of angle is 74 degree. The cleavage surface density of 2? 78 ~ 91 g / cm 3. is mainly produced in contact metamorphic intrusive rocks and limestone belt as the main mineral component of skarn.
- 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: Latex paint, wollastonite powder can replace all heavy calcium carbonate?
- The main ingredient in putty is double fly powder, and also acts as filling agent. (the proportion of fly powder in water resistant putty is 70~75%).
