- Q: Conglomerate can not be exploited to destroy
- Shale was formed in lentic environment, sediment deposition after a long time, so often exist in the lake and river deltas, formed in the continental shelf is shale, shale often contains ancient fossil plants and animals. Sometimes there are traces of animal fossils, and even traces of ancient raindrops may be preserved in shale.
- Q: Silica powder and calcite powder have big difference
- . Wollastonite is widely used in the fields of ceramics, chemical industry, metallurgy, paper making, plastics, coating and so on.
- Q: Can titanium, barium sulfate, calcium carbonate, wollastonite powder and talcum powder be transported by ordinary vehicles?
- Therefore, masks must be divided into size, size, masks and facial leakage rate varies from person to person.The dust of the road: scientific selection of certified GB2626-2006 standard anti-dust masks, contribute to the prevention of lung injury.1, choose double mask type. Disposable respirators are not suitable for long-term or occupational protection due to high leak rate.2, select the KN100 level. High dust environment, low protection rate will lead to physical damage.3, choose silicone mask, the service life is relatively long, soft and comfortable. Wear for a long time, it is not easy to cause allergic reactions. A mask with a high hardness can easily cause a facial impression.4, mask size, this is extremely important. It is not recommended to buy so-called universal models of masks that are prone to leakage.5, mask covered with nose and mouth, covering the mouth and nose and jaw 2 kinds, it is recommended to use the latter, relatively comfortable.6, it is recommended to choose breathing smooth mask. Some masks use double filter cotton + double filter surface design, relatively smooth breathing, and long service life.
- Q: What are the surface modification methods and processes of wollastonite?
- The treatment of wollastonite with silane coupling agent by surfactant modification can greatly improve its compatibility with polymer and enhance the filling effect, but the production cost of silane coupling agent modified is higher. Therefore, in some applications, the available surface active agent is cheaper, such as stearic acid (salt), quaternary ammonium salt, polyethylene glycol, fatty alcohol polyoxyethylene ether (nonionic surfactant) on surface modification of wollastonite powder. These surfactants are coated on the surface of particles by polar groups and particles, which can greatly enhance the lipophilic properties of wollastonite fillers... Details can be seen on the powder technology.
- 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'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: 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: Main characteristics of Wollastonite
- The chemical formula of wollastonite is CaSiO3, the structural formula is Ca3[Si3O9], and the theoretical chemical components are CaO 48.25% and SiO2 51.75%. In nature, pure wollastonite is rare, and in its formation, Ca is sometimes replaced by Fe, Mn, Ti, Sr plasma, and is isomorphous, with a small amount of Al and trace amounts of K and Na.
- 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: Does plastic modification add wollastonite to improve tearing properties?
- However, the tearing properties of materials are generally applicable to films. If this is the case, I estimate that the tear properties of the film will not be improved by adding mineral fillers
