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:Can I use wollastonite mill or vertical mill for wollastonite powder?: The large particle size of the needle like structure of wollastonite is limited by the long radius failure, but if the ultrafine powder is produced, it is recommended to use the air mill.

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.

Q:Conglomerate can not be exploited to destroy: The conglomerate is defined by more than 50% particle diameter greater than 2 mm is composed of clastic rock. The degree of rounding better gravel cementation and become conglomerate; with the edges of the corner by gravel, gravel and cement as breccia.

Q:What is the difference between wollastonite powder and calcium carbonate?: Wollastonite is calcium silicate and calcium carbonate is carbonate.

Q:World resources of Wollastonite: The United States (NYCO, the earliest wollastonite manufacturer in the United States, New York and India have the resources, in the low-end market has extended to the foot of hunting, wollastonite application technology industry), India (Wolkem India Ltd.), Finland (Finland Nordkalk is one of the top five wollastonite manufacturer in the world was bought in 2002 by Finland. The group, Mexico and South Africa (Namaqua) Wollastonite (Pty.) Ltd. with the mineral resources aspect ratio, but the iron is relatively high, Namibia, Spain),

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:Salt bath and bath salt is what?: Salt bath and bath salt there is no mineral salt.

Q:What's the use of wollastonite powder in coatings?How do you use it?: Coating wollastonite powder has a good reinforcing effect, which can improve the coating toughness and durability, and can keep the paint surface smooth and good gloss. But also improve the washing resistance and weathering resistance performance, but also can reduce the amount of oil paint and ink and alkali, has corrosion resistance. High quality color bright paint is obtained, and has good levelling property and aging resistance. The coatings can get better mechanical strength, increased durability, enhanced adhesion and corrosion resistance. There is good coverage rate and adhesion.
