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.
Q:What are the raw materials of cement products? What's the function?
Cement has a great influence on the properties of concrete. The kinds and quantities of cement containing minerals and the fineness of cement will affect the quality of cement products. The calcium silicate three in cement is an important factor in the coagulation of cement products. The reaction between three calcium silicate and water leads to the production of hydrated calcium silicate, and the hydrated calcium silicate gel acts as a cementing agent for aggregate and aggregate in concrete.
Q:What is a building energy-saving materials?
As far as its varieties are concerned, the new wall materials mainly include bricks, blocks and slabs, such as clay hollow bricks, waste clay bricks, non clay bricks, building blocks, aerated concrete, light plates and composite boards.
Q:What's the use of low carbon steel insulated nail hooks for power plants?
Mild steel is a type of carbon steel, and its carbon content is between 0.1% and 0.3%. The so-called carbon steel is also called carbon steel, refers to the carbon content of less than 2.11% of the iron carbon alloy. As we all know, the carbon content of the impact on the iron and carbon alloy is very large, the higher the content, the greater the hardness, but the smaller the toughness, and therefore easy to damage. Low carbon steel, because of its low carbon content, therefore, good toughness, low hardness, easy to carry out a variety of processing, such as welding, forging, etc.. And after some heat treatment, low carbon steel can obtain various properties, such as wear resistance, corrosion resistance and so on.
Q:What is dew point of thermal insulation material?
Insulation materials, insulation for industrial equipment and piping, thermal insulation measures and material aerogels were first applied to the space suit thermal insulation linings developed by nasa. With low thermal conductivity, small density, high flexibility, fire, waterproof and other characteristics. Its temperature coefficient of thermal conductivity 0.018W/ (K = m) and absolute waterproof, insulation performance is 3~8 times of traditional 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: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:Eterpan and yinte in what is the difference?
Eterpan:Eterpan, is a kind of fiber reinforced silicate plate (fiber cement board), the main raw material is cement, plant fiber and minerals, the flow of high temperature steam pressure and slurry method, mainly used as building materials.Eterpan is a kind of high strength, durability and other advantages of fiber silicate sheet, with various thickness and density, 100% does not contain asbestos and other harmful substances. For non combustible A1 grade products.The utility model has the advantages of fire prevention, moisture proof, waterproof, sound insulation effect, environmental protection, quick installation, long service life, etc.. Often used for wall panels, bathroom partitions, outdoor roofing, roofing, exterior insulation panels, interior decoration, ceilings, etc.; alsoInstead of gypsum board, used as base material in decoration.
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:Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?
The two are thermal insulation materials. Calcium silicate board strength, cheap, but the use of temperature is not high, the highest 1000 degrees.
