1. Product introduction

Wollastonite belongs to triclinic, crystal usually extends along Y-axis and becomes board shape, bacilliform or acicular. Pure wollastonite appears to be white, ivory-white light gray, light green or pink colour. Its appearance has vitreous luster.

Our company can manufacture many kinds of fine wollastonite powder, it is all manufactured by high quality raw materials. It has many good characteristics, such as granularity equality, homogeneous, high purity, endless catenulate, acicular crystallize, high whiteness, low ferrous, minimum S, P, low oil-absorption and etc.

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: Silica powder and calcite powder have big difference: 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.

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

Q: The function of wollastonite powder: Wollastonite after finishing has the characteristics of high aspect ratio (10:1-15:1), high whiteness and so on. Has been widely used in plastics, rubber, coatings, ceramics, friction materials, insulation materials, building materials and other industries.

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 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: 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: Salt bath and bath salt is what?: Bath salt is a kind of mineral salt, not a large granule of salt, mainly contains: magnesium: anti sensitive function, sensitive to the skin, particularly effective. The function of replenishing dampness is one of the important factors that exert the function of enzymes in the body, and can promote the activity of cells. K: it is one of the important factors to balance water, and can help to regenerate cells and increase metabolism. Calcium: balance the amount of mineral cells in the body, but also relieve the role of the skin. Bromide: has the function of treatment, soothing and disinfecting, and also relaxing the nerves. Sodium: it provides the energy that transports oxygen into and out of the cell surface membrane and makes it more balanced. Zinc: accelerates wound healing. Sulfur: disinfection, bactericidal function. Chloride: has the balanced effect of improving cell minerals. Natural mineral salt and acne natural mineral salts have a certain effect on acne, sores, allergic dermatitis, athlete's foot, metal allergy, insect bites, abscess, psoriasis, urticaria, dermatitis, rough skin, skin disease, senile skin pruritus, alopecia dandruff, etc.. Of course, severe symptoms, but also with the doctor's treatment.

Q: Does plastic modification add wollastonite to improve tearing properties?: The question is a bit vague. For example, PP+20% wollastonite modification, the tensile strength, modulus and other aspects will play a certain degree of improvement, if you say the tearing property is one thing with stretching it, then obviously improved.
