What does common light qualitative firebrick have?

Light qualitative firebrick, heat preservation brick, adiabatic brick, it is to belong to series product, with correspondence of heavy qualitative brick is light qualitative brick.


Pledge brick of argillaceous heat preservation and general firebrick are compared gently, weight of firebrick of light heat preservation is light, interior decorates hole equably small, hole rate is high. Accordingly, can make sure boiler setting comes loose heat is little, fuel cost can be reduced accordingly, light brick also means harbour quantity of heat small, heat cooling rate is rapid, allow to accelerate periodic operation. Firebrick of light heat preservation applies to 900 ℃ ～ limits of 1650 ℃ temperature.
Light qualitative tall aluminous brick pledges tall aluminous brick is the important heat-insulating material on hot project furnace gently. Reasonable make and choose light qualitative tall aluminous brick, reasonable use the sources of energy. Carry out policy of our country energy correctly to have important sense. In all sorts of light qualitative insulation material, light qualitative tall aluminous brick has taller fireproof sex. The size is small; Raw material is rich, firebrick is low-cost, it is good insulation material. According to different workmanship, light qualitative tall aluminous brick can pass bubble or add a character to be made.
What pledge Mo Laishi brick is JM23.JM26.JM28.JM basis to use temperature by brand cent gently is different, main component is.1450 of 1350 Mo Laishi brick Mo Laishi of.1550 of Mo Laishi brick the brick. Pledge the function of Mo Laishi brick reachs his to apply: gently? Dash forward parrot wishs above of ℃ of?790 of Lu  gauze. Loading bate begins temperature to be 1600~1700 ℃ . 1.5-4.5MPa of intensity of normal temperature compression. Hear resistance is good. Have two kinds of kinds: Agglomeration not comes stone brick and electric frit Mo Laishi brick. Agglomeration not comes stone brick is main raw material with tall bauxite grog, join a few clay or immature soil mine to serve as adhesive. Fire and into. Electric frit not comes stone brick is made by tall alumina. . It is raw material with industrial alumina and saggar, join charcoal or coke grain to serve as reducer, method of reductive report frit is used after shaping.
Pledge diatomite brick is the light qualitative brick that raw material makes with natural and poriferous diatomite gently. Natural diatomite is alga what form after organic matter is cankered is soft poriferous and mineral. Bases is 2: Oxidation silicon (73%~95% ) , have good heat proof quality. Join in diatomite a few clay and can burn material, classics embellish is wet mix. Shape and burn, make the product of different figure. The complexity cent of grid appearance is standard type. General. According to bulk density, different and special model cent is 6 kinds. Bulk density limits: 1 ／ of 0.4 ～ Cm3, coefficient of thermal conductivity is 300 ℃ M.K of ／ of 0.13 ～ 0.21w, intensity of normal temperature compression 0.6 ～ 2.5MPa, fireproof temperature amounts to 1280 ℃ , use temperature 1000 ℃ of 900 ～ . Use as industrial kiln. Heat preservation equipment and conduit. Insulation material.
Firebrick of heat preservation of silicon of light qualitative silica brick calls light qualitative silica brick normally, basically be raw material with fine silicon, its are critical granuality does not exceed 1mm normally, and be less than 0.5mm grain among them not less than 90% . In the slop that makes light qualitative silica brick, general mix into enters 35-45% anthracitic or about 30% coke serve as can light additive, granuality is less than 1mm. The adhesive in slop. Choose and add of mineralizer the amount is basic and as same as production silica brick. The fireproof sex of light qualitative silica brick and the common silica brick that are the same as into split phase do not have too big distinction. Why because air hole is much,compression intensity is. Fight broken bits sex. Corrosion resistance is inferior to common silica brick. The use temperature of light qualitative silica brick does not exceed 1550 ℃ , do not contact material of high temperature melt directly, do not accept the impact of aggressivity gas continuously. Light qualitative silica brick is a kind by utility cent. 2 class. One form product is used at steel rolling heating furnace industry of top, firebrick burns or kiln supports, can contact blaze directly, 2 form product is used at industry to heat up labor facilities partition.
The construction method of brick of light qualitative heat preservation pledges the build by laying bricks or stones of heat preservation brick is built gently is a meticulous project. To satisfy the quality requirement of each link in construction process, must notice careful construction strictly. Often check. It is the relevant construction method of kiln wall and kiln top heat-insulation layer below, offer reference. Build by laying bricks or stones of heat preservation brick is built. The height of heat preservation wall. Ply and total length must accord with the regulation of blueprint paper. Its build by laying bricks or stones builds method and argillaceous firebrick identical, use fireproof mud build by laying bricks or stones to build. Body of build by laying bricks or stones should make sure mortar is full, mortar is full degree should achieve 95% above. When bricklaying forbidden knock a brick with hammer, knock bricky surface gently with rubber hammer correctional. Forbidden the knife that use ash cuts a brick directly, cut machine cut is orderly. To avoid heat preservation bright fire is contacted directly inside brick and kiln, firebrick build by laying bricks or stones can be used to build all round observation hole, cotton of heat preservation wall, heat preservation, outside the wall is built receive a brick to also use argillaceous firebrick build by laying bricks or stones is built.
