The stand or fall of kiln furnace heat preservation and heat proof quality also affects the service life of the actor bad of product quality and kiln furnace directly. Kiln furnace heat-insulation layer uses brick of Mo Laishi heat preservation is the adiabatic and fireproof product that makes for main raw material with Molaishi. Have high temperature resistant, strength tall, thermal conductance is low, can contact blaze directly, apply to the liner of all sorts of industrial furnace kiln.
The tall aluminium that gives priority to brilliant photograph with Molaishi pledges we weigh fireproof material pledge gently for Molaishi heat preservation brick. General alumina content is in 65% ～ 75% between. Mineral composition divides Molaishi outside, contain alumina among them inferior person still contain a few glass photographs and Fang Shiying; Contain alumina taller person still contain a few corundum.
Heat preservation project is a painstaking work, each link should let achieve quality to ask to pay attention to essence of life strictly to be checked construction, frequently in construction process.
Fireproof insulation material chooses a principle 1, the function of kiln furnace and hot project characteristic. The kiln furnace that works like clearance sex should choose the material with small thermal capacity. 2, intensity of system of the safe use temperature of material, heat conduction, high temperature, chemical stability. 3, use life. 4, investment expenses upholds charge with what move. Generally speaking, the fireproof material that pledges again emphasizes particularly on quite some specifications index, wait like high temperature stability, chemical stability; Be able to bear or endure to pledge insulation material pays attention to investment and the integrated technology economic norms that move more gently.
The two side wall of the kiln of heat preservation channel that heat preservation plaster and ash seam requirement kiln wall are all body of build by laying bricks or stones all asks plaster is full, and inside wall firebrick and build by laying bricks or stones of brick of light qualitative heat preservation build ash to seam a requirement to be less than 3mm, plaster is full degree should achieve 90% above, and want a fault seam build by laying bricks or stones to build. First, inside wall ash is seamed full degree will tell, through construction of many channel kiln the examination proves the level seams plaster full degree can achieve 90% above, but vertical stroke seams plaster full spend some to was not achieved 90% , the vertical stroke that has 5~8% even is seamed appear from apparently look have plaster and actual inside the circumstance that does not have plaster however, the plaster that seams the surface is hind wipe, actually vertical stroke is seamed is to be seamed for nothing. When channel kiln ignition runs, firebrick and body of build by laying bricks or stones of brick of light qualitative heat preservation are being pressed inside kiln (when carrying a car on the head, it is to be being pressed completely almost inside kiln) when, in heating up air current to be seamed from these sky, outward change takes heat-insulation layer, make temperature of surface of the wall outside kiln designs a requirement more than greatly, be lost of many quantity of heat. At the same time as a result of a car there is a to expand on long firebrick wall seam, make its make an independent short wall, move in the change of thermal current fall to make the wall tilts upcountry very easily, affect the life of channel kiln. Next, the ash of firebrick and brick of light qualitative heat preservation seams a design to ask is to be less than 3mm, but because deviation of the set dimension in the standard has,having negative, losing deviation to be more than 3mm sometimes, be like ± 2, this is more than 3mm, at this moment ash is seamed uncontrollable to be less than 3mm. To achieve design requirement, use a brick to live the standard door of different measurement first in construction, the firebrick of same size or departure of brick of light qualitative heat preservation. Can follow same bid when bricklaying the bricky build by laying bricks or stones of dimension is built together, make its ash is seamed achieve the requirement that is less than 3mm. Otherwise ash is seamed be more than 3mm, in causing ash to seam, drying shrinkage hind has space easily, make hot air current outward when be being pressed change, heat up a loss not only big and influential to the life of kiln. The ash that build by laying bricks or stones of exterior wall tile builds seams a design to ask to be less than 7mm, same standard and vertical stroke seam requirement plaster full, after the surface outside kiln wall is carbonadoing kiln ends, with cement former oar is ticked off seam. Build by laying bricks or stones of brick of firebrick, heat-insulation layer, heat preservation, exterior wall tile is built should undertake at the same time, and by in retreat stage build by laying bricks or stones to build outwards. The build by laying bricks or stones that project of kiln wall heat preservation basically is heat preservation brick builds the laid with heat-insulation layer.
The height that build by laying bricks or stones of brick of heat preservation of Mo Laishi of kiln furnace heat-insulation layer builds heat preservation wall, ply and overall length accord with the regulation of blueprint paper. Its build by laying bricks or stones builds method and clay qualitative firebrick is identical, use fireproof slop build by laying bricks or stones to build. System of build by laying bricks or stones should make sure grey full oar is solid, its plaster is full degree should achieve 95% above. Forbidden use hammer knocks a brick when bricklaying, the face that uses rubber hammer light clap to hit a brick looks for his. Forbidden the knife that use ash chops a brick directly, the cut of applied cut machine that needs treatment is orderly. To avoid heat preservation brick direct with bright fire is contacted inside kiln, of observation hole all around build by laying bricks or stones builds usable firebrick, heat preservation wall and heat preservation cotton and outside of the wall build receive a brick to also apply clay to pledge firebrick build by laying bricks or stones is built.
Buy kiln furnace heat-insulation layer to use brick of Mo Laishi heat preservation, recommend flourish Cheng Naicai to you, flourish Cheng Naicai is fireproof reach industry of insulation material type of production, it is the omnibus enterprise that market scientific research, experiment, development, production, sale and client are an organic whole. The factory is located in beauty abundant " be able to bear or endure of material " , Henan visits new close city. Natural resources of the aluminous alumina with rich churchyard, coal, and convenient traffic offerred advantaged condition for the production of fireproof material and service.
Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
