Fireproof material has thermal insulation heat preservation brick, cotton, blanket, felt, can be in hundreds of consummate use in 1000 degrees high temperature environment, it is the important data that high temperature industry can use, can have environmental protection, energy-saving, managing effect.
The use of fireproof material assured heat preservation not only architectural safety performance, and managing resource. Heat preservation is fireproof material is approbated with what its superior performance got a client. But because fireproof material quality is uneven on the market, the note needs when buying insulation material: 1. See the surface of the product above all. Proposal product surface is slick. If have scar or damage, the proposal does not choose 2. The main characteristic of insulation material is fireproof sex, reduce the loss when fire. When buying, check the burning behavior of the product. 3 lighting cliff cotton product is a proposal. Fireproof material has thermal insulation good hygroscopic very important also. It can maintain a room for a long time dry, have moistureproof effect. Performance of poriferous moisture absorption is good the development as bldg. , rise ceaselessly to the requirement of housing materials, more and more housing materials are ceaseless emerge in large numbers, heat preservation is fireproof the development of material also got affect. Current, the applied limits of fireproof material enlarges heat preservation ceaselessly. Heat preservation is fireproof the advantage of material: 1. Flexibility and fireproof sex are tall, application is wide. 2. Weight is light, carry go to the lavatory simply, construction is convenient. 3. Coefficient of thermal conductivity is low, high temperature resistant the gender is good. 4. Heat preservation effect is good, waterproof effect is good.
Heat preservation is fireproof material is a kind of porosity the fireproof stuff with low density of tall, bulk, apply extensively at disparate industry industry, have the function that reduces heat loss due to radiation not only, and have fire prevention flame retardant function, although be below high temperature, still won't be out of shape, achieve ideal energy-saving result. As the ceaseless development of fireproof data industry and development, scale of production and sale are in the world all the time the first, but the trend that also accords with market development, basically be environmental protection, energy-saving, already made one of main products that fireproof data industry develops future quickly. because such, a lot of enterprises joined fireproof data industry. Enhance work efficiency and security better to ensure, be being bought and use heat preservation when fireproof material, must notice, lest cause needless loss.
Choose heat preservation what principle does fireproof material have? The main function of kiln basically is decided by the technical economic performance of fireproof material, cost of the investment cost that affects kiln directly, character of service, thermal efficiency, moving specific power consumption. The general principle of fireproof insulation material: 1. The function of kiln furnace and hot project are characteristic. If kiln furnace clearance works, should choose the material with small thermal capacity. 2. The safety of material uses intensity of system of temperature, heat conduction, high temperature, chemical stability. 3. Service life. 4. Investment cost and operation maintain cost. Generally speaking, heavy simple fireproof stuff pays attention to the specifications index such as high temperature stability, chemical stability more; The investment that pledges insulation material pays attention to integrated technology economic norms more gently and move.
Fireproof insulation material can divide by use temperature for: (Heat insulating materials of 1) low temperature, use temperature under 900 ℃ . Main product has asbestine of diatomite brick, bubble, expand to pledge cotton of vermiculite, mineral wool, cliff, glass cotton, gently the goods such as Mo Laishi brick. In last few years again coating of cellular glass, siliceous magnesian heat preservation waits to be tasted newly + kind appear. (In 2) lukewarm heat insulating materials, use temperature is 900 ～ 1200 ℃ . Basically have diatomite brick, expand products of fiber of brick of pearlite, light qualitative clay and common and siliceous aluminium and stone of hard silicon calcium siliceous calcium. (Heat insulating materials of 3) high temperature, use temperature is more than 1200 ℃ . Main product has product of brick of light qualitative tall aluminous brick, light qualitative corundum, light qualitative magnesia brick, hollow ball, float bead goods, high pure siliceous aluminous fiber. (Heat insulation of 4) normal temperature and keep cold data, use temperature is normal temperature or under room temperature. Main breed has goods of aerocrete, gesso, expanded plastics and other organic heat-insulating material. The internal composition according to insulation material condition can be insulation material cent shape of porous qualitative insulation material, fiber insulation material and complex structure insulation material.
When choosing light qualitative insulation material, the coefficient of thermal conductivity that uses insulation material commonly (δ ) the cost with insulation material of each unit bulk (\ ) will decide. Coefficient of thermal conductivity is small, explain effect of insulation material heat preservation is good, cost of the energy when moving is low. Cost of insulation material of each unit bulk is low, explain investment cost is low, investment economy effect is good. Optional choose coordinate pursues, working temperature is horizontal coordinate, working temperature is horizontal coordinate, data security uses temperature to be, each material curve uses temperature for the safety of material, technical economic performance is good.
