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: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 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: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: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:What are the surface modification methods and processes of wollastonite?
Wollastonite is a calcium metasilicate mineral, often white and greyish white, with a glassy luster to a pearly luster. Because of its non-toxic, chemical corrosion resistance, thermal stability and dimensional stability, good mechanical and electrical properties, as well as strengthening and other advantages, it is widely used as reinforced fillers for polymer matrix composites.
Q:Use of Wollastonite
Wollastonite has a wide range of uses, including construction, ceramics, coatings, paint, rubber and plastics industries.
Q:Addition of needle like wollastonite in engineering plastics
Wollastonite is added to engineering plastics, which is called calcium plastic in the industry, because slaked lime is calcium hydroxide and lime is calcium carbonate. In order to increase the strength of the plastics, the calcined wollastonite is added.
Q:Can wollastonite be certified by REACH?
In addition, you need to know whether you are talking about whether the wollastonite is a natural substance or not. If it is a natural mineral, there is no need to deal with REACH. It can be exempted.
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..
