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 is the difference between calcium silicate board and cement fiber board?
How to distinguish fiber cement, pressure plate and calcium silicate board?1, calculate density: calcium silicate board density is much lower than the fiber cement pressure plate, through the weight of the plate can calculate its approximate density.2, look at the color: Although there are manufacturers in order to pretend to be fiber cement pressure plate and deliberately add carbon black and so on, the board made dark, but not natural cement color.3, ask whether there are super thin plate and super thick plate, if not or can not do, it means that he is selling calcium silicate board or ordinary fiber cement, non pressure plate.4, if you go to the factory, you can visit its workshop, if there is steam pressure (commonly known as bullets), it is certainly calcium silicate board manufacturers, if there is no press, it is a common cement plant.
Q:Calcium silicate board for house ceiling, 6mm or 8mm?
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: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:What's the use of white portland cement?
All the raw meal with the proper components up to the partial melting of the calcium silicate as the main ingredient, the iron content in clinker less addition of gypsum, white water ground made of rigid cementitious material, called white portland cement (the white cement).When grinding cement, allow limestone not to exceed 5% of the cement weight.Note: cement is allowed to be added to the grinding mill without damaging the cement properties. The amount of cement added shall not exceed 1% of the cement weight. The addition of additional substance must be tested and reported to the Ministry of construction materials for approval.
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 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:What are the main use of lime?
A rigid inorganic cementitious material consisting mainly of calcium oxide. Lime is made from limestone, dolomite, chalk and shell with high content of calcium carbonate and calcined at 900~1100 DEG C. Lime is one of the earliest cementitious materials used in human life. Lime is widely used in civil engineering and can be used in medicine in our country.
Q:Which is better, asbestos free calcium silicate and aluminium silicate refractory fiber?
Aluminum silicate fiber can be divided into many kinds according to the aluminum content, the use temperature range is relatively large, the heat insulation property is good, but the price is more expensive.
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.
