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.
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: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:Cement is not silicate products
Usually refers to silicate products with lime (calcium containing materials) and sand, fly ash, slag (siliceous materials), then add a small amount of gypsum, the steam steam curing or steam curing, building products quickly generate Tobey mullite, calcium silicate, hydrated calcium aluminate sulfate and hydrated calcium aluminate such as cementitious materials and production. Such as: autoclaved fly ash (sand), autoclaved aerated concrete, autoclaved fly ash brick, autoclaved sand lime bricks.
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 for house ceiling, 6mm or 8mm?
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. Mineral wool board is mineral fiber cotton as raw material, the biggest characteristic is to have good sound absorption and heat insulation effect. Its surface has the effect of knurling and relief, such as star, caterpillar, cross flower, central flower, walnut line, stripe and so on. Mineral wool board can sound and heat insulation, fire prevention, any products do not contain asbestos, harmless to the human body, and has anti sag function.
Q:How to make building glue?
The invention relates to an architectural adhesive, which is characterized in that the composition of the building glue comprises 28-50wt% sodium silicate water solution, 34-53wt% quartz sand and 8-35wt% magnesium silicate.Adhesive for a building, it is the following: the weight ratio of 4 to 6, PVA cellulose 6 - 12, 1 - 2, copolymer admixture from 0.01 to 0.05, according to the proportion of polyvinyl alcohol with hot water first fully dissolved, then adding cellulose, copolymer, admixture and stir evenly. The glue can be combined with Portland cement or construction gypsum to cement all kinds of light plates. This product is non-toxic and tasteless, harmless to the human body, is a wide range of uses, superior technical performance of environmentally friendly building adhesive.
Q:What are the high temperature resistant insulation materials at 400?
According to the general rules of equipment and piping insulation, heat insulation material is a material with a thermal conductivity of less than 0.14W/ (m*K) when the average temperature is equal to or less than 623K (350 degrees Celsius). Heat insulation material is usually light, porous, porous, small thermal conductivity characteristics. Generally used to prevent heat loss of equipment and pipes, or frozen (also known as general cold) and low temperature (also known as cryogenic) use, so in our country, insulation materials, also known as insulation or cold preservation materials. At the same time, because of the porous and fibrous structure of thermal insulation material, it has good sound absorption function, so it is also widely used in the construction industry.
Q:What's the use of low carbon steel insulated nail hooks for power plants?
The current power plant thermal insulation is mainly carried out by use of various types of insulation materials, thermal insulation materials commonly used include calcium silicate products, pipes, rock and aluminum silicate fiber products, due to their different properties are applicable to different environments. The equipment with temperature at 300-600 DEG C often adopts aluminium silicate products and calcium silicate products to compound heat preservation. While the temperature is less than 300 degrees, the mineral wool products are usually used for thermal insulation.
Q:What are the main use of lime?
Lime milk and mortar, slaked lime or lime paste, with lots of paint. Lime mortar or slaked lime powder can be used to prepare lime mortar or cement lime mixture mortar for masonry or plastering engineering.
