Q:Latex paint, wollastonite powder can replace all heavy calcium carbonate?
Shuangfei powder is also called the "big white", the main component is calcium carbonate, also referred to as "tsp". Is widely used in ceramics, rubber, plastics, paper, paint, paint, ink, cable, food, medicine, textile, feed, toothpaste and other daily chemical industry as a filler to increase the volume of products, reduce the production cost.
Q:What's the role of wollastonite in ceramic fiber products?
Wollastonite is a new type of industrial minerals, with its unique physical and chemical properties of mineralogy, and are widely used in ceramics, paint, rubber, metallurgy, casting, welding, abrasive, glass, mineral wool and other industrial sectors. Wollastonite is an ideal raw material for asbestos substitutes.With the continuous development of science and technology, the application research of wollastonite is more and more thorough. The improvement of the grinding method of wollastonite and the obtaining of ultra fine grade wollastonite powder will continue to develop new application fields of wollastonite.
Q:The difference between wollastonite and calcite
Calcite powder is commonly used in powdered inorganic filler with high chemical purity, inert, easy chemical reaction, good thermal stability, high whiteness, low oil absorption, soft, dry, no crystal water, low hardness, abrasion value, non-toxic, tasteless, odorless, dispersion, etc.. Widely used in plastics, rubber, paper making, coating, feed, medicine, daily chemicals, glass, ceramics and other fields.
Q:What is the difference between wollastonite powder and calcium carbonate?
Wollastonite is calcium silicate and calcium carbonate is carbonate.
Q:Conglomerate can not be exploited to destroy
Shale was formed in lentic environment, sediment deposition after a long time, so often exist in the lake and river deltas, formed in the continental shelf is shale, shale often contains ancient fossil plants and animals. Sometimes there are traces of animal fossils, and even traces of ancient raindrops may be preserved in shale.
Q:Does exterior wall coating talcum powder replace wollastonite powder?
Can replace. Generally use talcum powder for exterior wall coating. Wollastonite is seldom used.
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: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:Can wollastonite be certified by REACH?
There are issues related to REACH consulting Huace Mario, or leave your contact information, Huace swico is a listed company in the REACH industry background, is the absolute leader.
Q:Excuse me, why is paste tile with stone powder, paste wall tiles with river sand?
Put tiles on the ground, does not appear to be falling, and floor tiles, is to put the thickness of 5 cm above the powder and cement mixture of flat ground, large amount of material, on the ground, it is easy to compaction, cement and powder with cohesive force as long as appropriate, can satisfy the requirement of use, floor tiles posted above in the leveling layer, floor tiles will put bricks before the water wet, and then glued only cement paste, is affixed to the above, it is ensured that the combination of brick and cement, stone powder mixture firmness.
