Q:What heat preservation material is used for thermal insulation of steam pipe in power plant? How thick is the bag? Please advise!

Steam pipe in power plant thermal insulation rock wool board thickness, according to the temperature in the pipeline to choose, the higher the temperature insulation thickness is generally 80 to 150 mm.

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 three major effects of fly ash in concrete?

The "form effect" of fly ash contains many glass beads, the surface is smooth and the texture is dense. It is this form to water reducing effect, compact and homogeneous effect, can promote the early hydration of cement flocculation effect of solution, change the mixture rheological properties, the initial structure and hardening of the various functions, especially for pumping concrete, can play a good role in lubrication.

Q:Calcium silicate board for house ceiling, 6mm or 8mm?

Calcium silicate board with fire prevention, moistureproof, sound insulation, thermal insulation, indoor air in wet conditions can attract water molecules in air, air drying, and the release of water molecules, can adjust the indoor humidity, dry, increase comfort. Natural gypsum products and special fireproof material, the flame can produce endothermic reaction, at the same time, the release of water molecules to prevent the fire from spreading, and does not produce any toxic decomposition, corrosive and choking gas, will not produce any smoke or combustibles.

Q:What is the best price for the use of calcium silicate ceiling?

Neither calcium silicate nor silicate boards are afraid of water because they are mixtures of gypsum and fiber.

Q:What's the difference between white carbon and carbon black? Can they be replaced?

Carbon black is the floorboard of white powder X- ray of amorphous silica and silicate products, mainly refers to the precipitated silica, fumed silica, ultrafine silica gel and gel, including powder synthetic aluminium silicate and calcium silicate. Silica is a porous material, its composition by SiO2 nH2O, where nH2O is there the surface hydroxyl form. Soluble in caustic and hydrofluoric acid, insoluble in water, solvent and acid (except hydrofluoric acid). High temperature resistant, non flammable, tasteless, odorless, has the very good electric insulation.

Q:Why is calcium silicate board unsuitable for use in home improvement?

It is not the appropriate material, calcium gypsum board to hemihydrate gypsum and organic silicone oil as the main material, the surface of the organic silicone oil with the installation way friction transportation will fall, a long time will get loss loss, if the poor quality of the organic silicone coating, it is not full proof effect is worse in the course of time, deformation, damp, moldy yes, yellow.

Q:What is a building energy-saving materials?

Mainly include new wall materials, insulation materials, waterproof sealing materials, ceramic materials, new chemical materials, decoration materials and various industrial waste residue comprehensive utilization.

Q:What are the raw materials of cement products? What's the function?

Water is necessary for the production of cement products, the role of water is to cement hydration. Generally, the water cement ratio of concrete is 0.40~0.65. If the water is too large, it will leave a hole in the concrete, which will affect the strength, density and durability of the concrete and even cause water leakage.

Q:Eterpan with calcium silicate is sold on the market are the same thing? Non asbestos calcium silicate board is Eterpan it

Eterpan is calcium silicate board there is a famous brand. Non asbestos calcium silicate board has many kinds, Aitken is just one.
