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?
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
Q:The function of wollastonite powder
Wollastonite chemical composition close to the theoretical value, high purity, fine acicular structure, with low loss, harmful components (MnO, Fe203) content is low, the indicators better than similar domestic ore.
Q:What is the difference between wollastonite powder and calcium carbonate?
Wollastonite is calcium silicate and calcium carbonate is carbonate.
Q:Does exterior wall coating talcum powder replace wollastonite powder?
High surface finish. And the price is cheaper than wollastonite. Able to reduce costs. It is recommended that you use poly brand coating grade talc powder.
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:Chemical TSP and wollastonite filled nylon do contrast to the good toughness
Cleaning and coated with anti - reflective film lenses, such as cameras, slide projectors, microscopes lens, can be used about 20% of alcohol preparation cleaning agent for cleaning. When cleaning application soft brush or cotton with a small amount of cleaning agent, from the lens center outward circular motion. Do not put this kind of lens soaked in cleaning agent cleaning; cleaning the lens shall not force wipe, otherwise it will scratch the antireflection film, lens damage.
Q:Use of Wollastonite
Wollastonite common powder and wollastonite needle powder are of different value. In addition to figuring out the main elements and the burning loss, the wollastonite in you can also see the particle shape in the powder state.
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 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.
