Q:What's the use of wollastonite powder in coatings?How do you use it?
Also found in certain deep metamorphic rocks: used as raw materials or fillers for paper making, ceramics, cement, rubber, plastics, gas filtration materials and heat insulation materials, metallurgical fluxes, etc.
Q:Latex paint, wollastonite powder can replace all heavy calcium carbonate?
Shuangfei powder is actually a "big white", if the brush on the wall, the surface cannot do other processing (putty, paint, etc.) must take this shovel back Shuangfei powder putty, can brush paint, otherwise, in this layer directly Shuangfei powder paint brush will peel a piece off. I have this lesson, I hope you will not be fooled again, repeat my mistakes.
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: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.
Q:The difference between wollastonite and calcite
Wollastonite is a kind of silicate, because the heat resistance of wollastonite with acicular, fibrous crystal morphology and high whiteness, good dielectric properties and high so it is widely used in ceramics, chemical industry, metallurgy, construction, machinery, electronics, papermaking, automotive and other industries.
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:Conglomerate can not be exploited to destroy
Round and sub round gravel with a particle size greater than 2 mm, accounting for more than 30% of the total amount of clastic rock. Clastic components in conglomerate are mainly debris, only a small amount of mineral debris, and the interstitial materials are sand, silt, clay and chemical precipitation material. According to the size of gravel conglomerate, divided into boulders (>256 mm), large conglomerate gravel (64 ~ 256 mm) pebble conglomerate, (4 to 64 mm) and fine gravel conglomerate (2 to 4 cents by the conglomerate and bioturbation limestone conglomerate m). According to the complexity of gravel composition, conglomerate can be divided into single component conglomerate and compound component conglomerate. According to the location of conglomerate in geological section, they can be divided into bottom conglomerate and interlayer conglomerate. The bottom conglomerate is located at the bottom of transgressive sequence, which is unconformity or pseudo contact with the lower rock layer, and represents the hiatus of a certain geological period. For example, Hebei, Tangshan, Sinian, bottom, the Great Wall, quartz conglomerate. The interlayer conglomerate is consolidated within the stratum and does not represent any erosion discontinuity. For example, the Cambrian and Ordovician carbonate rocks in northern china.
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:Main characteristics of Wollastonite
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:Addition of needle like wollastonite in engineering plastics
Generally add one percent to five percent, according to the experimental results to determine the amount of additional required. Add too much plastic, easy to powder. There are a lot of washing machine manufacturers, in order to reduce costs, adding ten percent or five years, washing machine shell automatically broken.
