Q:Silica powder and calcite powder have big difference
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:How does the result of wollastonite analysis convert the grade of ore-forming stone?
Wollastonite ore is mainly composed of quartz and calcite (SiO2) (CaCO3), wollastonite (CaSiO3), the three major minerals by chemical analysis method to detect SiO2, CaO, so from the chemical analysis results is not apparent
Q:The difference between silica powder and wollastonite powder
Wollastonite is a chain metasilicate, and is a kind of fiber like needle shaped
Q:Chemical TSP and wollastonite filled nylon do contrast to the good toughness
Chemical TSP and wollastonite filled nylon do contrast to the good toughness
Q:Use of Wollastonite
Wollastonite has a wide range of uses, including construction, ceramics, coatings, paint, rubber and plastics industries.
Q:Really useful stone powder and jade powder processing of jade? Do you glue it straight together or do you press it directly?
Yes, this approach is imitation jade, general imitation Gao Pinyu, but is the use of stone powder and jade powder with glue condensation, compression, surface, and then polished can be
Q:Excuse me, why is paste tile with stone powder, paste wall tiles with river sand?
1, cement mortar wall generally only a thin layer of powder, the larger particles can not meet this requirement, and the floor tiles of cement mortar generally above 5 cm, this problem does not exist, so the wall with fine sand, floor tiles can be used powder;2, because the wall is only a thin layer of cement mortar, bonding strength must be strong, can stick to the wall, otherwise, will be easy to fall, the formation of quality problems, can fine sand, sand and sand of the spacing between the inevitable small, it is easy to be filled with smaller particles of cement, so it will be cement, but can be combined to achieve both what no pores, so you can protect the brick wall and the adhesion area does not appear or rarely pore, so as to realize the brick wall and become one, as long as the cement strength is strong enough, it must firmly bond;
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:What are the specific applications of wollastonite in coatings?
The use of needle like wollastonite, 1 building materials industry: EPS thermal insulation mortar, interface agents, construction steel waterproof, ceramic tile, marble sealant, adhesive polystyrene board, calcium silicate board, powder coating, polymer mortar, anti cracking and impermeable concrete.
