Wollastonite

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: Chemical TSP and wollastonite filled nylon do contrast to the good toughness: Optical glass is used for lens, lens, prism, slide and so on. It is easy to be stained with oil, moisture, dirt and fingerprints in manufacture and use. It affects imaging and transmittance. Cleaning optical glass should be based on the characteristics of dirt, different structures, choose different cleaning agents, use different cleaning tools, choose different cleaning methods.

Q: What are the specific applications of wollastonite in coatings?: The use of needle shaped wollastonite 2. Friction materials: car brake pads, clutch plates, bumpers.The use of needle like wollastonite 3, plastic industry: Polypropylene frame, engineering plastics.Needle wollastonite use 4, ceramic industry: fiber ceramic panels, sanitary ware, glazed tile, etc..Needle wollastonite use 5, FRP Industry: all glass fiber reinforced plastic products.

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: What is the difference between wollastonite powder and calcium carbonate?: Calcium carbonate is a kind of inorganic compounds, commonly known as CaCO: limestone, limestone, limestone, marble etc.. Main ingredients: calcite, is a kind of compound, chemical formula is CaCO, neutral, basically insoluble in water, soluble in hydrochloric acid. It is common on the earth substances exist in aragonite, calcite, chalk, limestone, marble, Shi Huihua rock, also is the main component of animal bones or shell.

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: Can wollastonite be certified by REACH?: Wollastonite does not need to be tested, but pre registration and registration are required.

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: 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 talc powder?: The medicine - food grade (YS): medicine tablet, medicine powder (such as Paracetamol Caffeine and Aspirinpowder), sugar powder and traditional Chinese medicine prescriptions, food additives, separant.Talc (3) coating grade (TL): used for white pigment and various water base, oil base, resin, industrial coating, primer, protective paint, etc..
