- 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: 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: Can I use wollastonite mill or vertical mill for wollastonite powder?
- The large particle size of the needle like structure of wollastonite is limited by the long radius failure, but if the ultrafine powder is produced, it is recommended to use the air mill.
- 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?
- The stone powder is generally much cheaper than river sand, and the amount of floor tile is large, and the stone powder is much more economical and convenient to draw materials.Note: cement paste is usually used as cement wall, not cement mortar. Only when the wall surface is poor, cement mortar can be used when leveling layer is used.
- 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: Really useful stone powder and jade powder processing of jade? Do you glue it straight together or do you press it directly?
- This identification method has a variety of jade, can be as light but not dazzling, let the light, the permeability is insufficient, it can be across the glass, if it is true, draw the engraving is not false, but also by the method of distinguishing rubber jade.
- 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.
- Q: Salt bath and bath salt is what?
- Mineral salt is a salt, which contains many minerals, these minerals beneficial to human health, easy to absorb, containing silicate (SiO4) generic minerals (including silicon containing salt, other such as partial Portland, wollastonite CaSiO3 case). Can be regarded as a combination of SiO2 with other oxides (mostly metal oxides).
- 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.
