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: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:The difference between wollastonite and calcite
Calcite powder is commonly used in powdered inorganic filler with high chemical purity, inert, easy chemical reaction, good thermal stability, high whiteness, low oil absorption, soft, dry, no crystal water, low hardness, abrasion value, non-toxic, tasteless, odorless, dispersion, etc.. Widely used in plastics, rubber, paper making, coating, feed, medicine, daily chemicals, glass, ceramics and other fields.
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: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:Use of Wollastonite
Wollastonite has a wide range of uses, including construction, ceramics, coatings, paint, rubber and plastics 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:Can wollastonite be certified by REACH?
There are issues related to REACH consulting Huace Mario, or leave your contact information, Huace swico is a listed company in the REACH industry background, is the absolute leader.
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:Can I use wollastonite mill or vertical mill for wollastonite powder?
Vertical mill is Raymond mill, the use of high manganese steel grinding roller grinding ring, will not destroy the structure of Wollastonite
