Does where of heat preservation brick have sell?

Want to buy heat preservation brick? Each province, various places all has a sale, but the price, quality is uneven, does the where of heat preservation brick of case of high quality low have those who sell? Recommend advisory flourish Cheng Naicai, material qualitative, index, dimension all but custom-built, greeting incoming telegram seeks advice, or come to a factory make an on-the-spot investigation.



What is heat preservation brick? Weight the light, fireproof product that has effect of heat preservation heat insolation, take feel in the hand gently, resemble a biscuit, density of this series product is less than the firebrick of 1.3x103kg/m3. Because pledge heat preservation brick has density gently small, porosity tall, thermal conductance sex of small, heat preservation is good and the characteristic such as the compression strength with have particular, already won wide application on heat treatment equipment.
What advantage does heat preservation brick have? Have reduce kiln furnace weight, decrease wall of small pit boiler setting, change kiln furnace structure, rise warm up speed, reduce the sources of energy to use up, improvement works condition, increase the good point such as work efficiency.
The sort of heat preservation brick and brick of heat preservation of manufacturing technology introduction use material to differ character by place, basically brick of light qualitative clay, light qualitative tall aluminous brick, tall aluminium gets together light brick, Molaishi gets together brick of light brick, light qualitative silica brick, light qualitative corundum.
The production methods of light qualitative firebrick basically has 3 kinds: (1) can light accretion way, it is easy to join wood chip or anxious pink and so on in burden namely the combustible of burn-up, when the brick firing burn-up of the combustible in the process, leave a large number of hole inside the brick. This is commonly used method; (2) bubble law, add person colophony black to wait for blowing agent in burden namely, next firing and poriferous goods; (3) chemical law, some kind of substance is added in burden, can produce bubbly chemical reaction. For example dolomite or square magnesian stone add gesso, with rare vitriolic make foaming agent, generation is many from, instantly mould shapes, dry hind firing.
What should notice when is heat preservation brick used? Of the firebrick with brick of light qualitative heat preservation and general and same qualitative capable person fireproof degree differ not quite, loading softening point criterion slightly low. If light qualitative brick is long-term when be used below high temperature, can continue agglomeration break systole, cause crackle to be destroyed even. So majority pledges the brick has a limit to use the issue of temperature gently, be like limit of brick of light qualitative clay have 1150 ℃ only, light qualitative tall aluminous brick uses temperature not to exceed 1350 ℃ , pledge Mo Laishi brick uses temperature not to exceed 1500 ℃ gently, light qualitative silica brick can amount to 1600 ℃ . The problem with because light qualitative silica brick is nonexistent contractive high temperature, volume is steadier, accordingly can build by laying bricks or stones of in order to builds the liner that enrages a contact with furnace directly.
