- Q: What are the production methods of calcium silicate board material?
- The synthesis process of dynamic method is carried out under stirring, the synthesis temperature is higher than the static process, and under the compression condition. The dynamic method is simple, no gel chemical order, products made of small capacity, good performance, can obtain high temperature (1000 degrees Celsius) of xonotlite products and ultra light products, but the need for high pressure vessel with stirring device, equipment and process condition requires high energy consumption and investment are higher. At present, this method is adopted abroad.
- Q: What kind of insulation material can withstand 350-600 degrees of high temperature?
- GB 50264-97 code for design of thermal insulation engineering for industrial equipment and pipelines98T901 cold storage Atlas of piping and equipment
- Q: What are the high temperature resistant insulation materials at 400?
- Thermal insulation materials for thermal equipment and pipes are mostly inorganic insulation materials. This kind of material has the characteristics of no decay, no burning, high temperature resistance and so on. For example: asbestos, diatomite, perlite, glass fiber, foam glass concrete, calcium silicate and so on.
- Q: The ceiling of calcium silicate board and mineral wool board which is good
- The fire performance of third mineral wool board no calcium silicate board,Fourth mineral dampeasily yellow, moisture absorption is not good.The calcium silicate board will not have the above shortcomings, the thickness of 15mm if it is the calcium silicate board 4mm ceiling 600*600 thickness can reach the effect of the biggest advantages of mineral wool board, calcium silicate board also is not a burning fire, moisture absorption is very good, green building materials.
- Q: Calcium silicate board white ICI belongs to wood surface paint?
- ICI can generally be considered as wall paint (latex paint), and latex paint can be used on this kind of cement board. And lumber is different, it is not suitable to brush latex paint on the surface of wood, it can only be decorated with paint (oil paint).
- Q: Why is calcium silicate board unsuitable for use in home improvement?
- Because the silica plate contains quartz composition, and the content is still higher. Quartz is a carcinogenic substance, the long-term impact of this substance, the human carcinogenic probability will be greatly enhanced
- Q: What's the use of white portland cement?
- The typical feature of white cement is high whiteness, with bright color, generally used for a variety of architectural decoration materials, painting, sculpture, a typical floor, terrazzo, white cement can be used to produce white and colored concrete, is the largest cement production decoration.
- Q: What is the best price for the use of calcium silicate ceiling?
- Water will melt or become yellow, mildew. So if you choose their ceiling, you must first deal with the roof leak. Calcium silicate board with artificial and material prices of about 22 square meters, mainly for office space, and residential corridors and other public places decoration. Integrated ceiling is not afraid of water.
- Q: What's the use of low carbon steel insulated nail hooks for power plants?
- Low carbon steel nail insulation (aka: insulation pins) material: low carbon steel wire for power plants or stainless steel wire products: insulation nail. Hook nail is a power plant by mechanical processing of special insulation nail models: nail diameter: 3 mm with 3.5mm with 4 mm with 5 mm with 6 mm etc.
- Q: How to make building glue?
- An adhesive and a preparation method thereof, according to the proportion of the polyether and polyester resin, and multiple natural plant resin, polystyrene resin, solvent oil and ultraviolet resistant, anti-aging agent in the container, evenly stirring at 20 DEG -30 DEG C into TDI, heating up to 70 DEG -100 DEG 2-5 hours of stirring that uniform to room temperature, adding industrial gasoline diluted into oil, the transparent liquid is liquid, of course, according to the need of color, can also add to the metal paste color. The main feature of the invention is to glue sealing watering Ni bare surface, to set free, waterproof, anti cracking and water conservation effect, while the antirust effect is far more than the anti rust paint several times.
