Get together brick of heat preservation of light Mo Laishi, bulk density is in commonly 0.6-1.2g/cm3, use temperature 1300 degrees - 1550 degrees, the recipe design of each level is unique, ask in order to satisfy the or else of the user with what use below the environment.
Brick of heat preservation of Mo Laishi seriesBe with high quality high pure raw material, add the filler that has strict classification by level, form the interstitial structure that agrees equably. Each face of the brick all comes through machining the dimension of need.
Characteristic:
1. low heat conduction is led
Have effect of very good adiabatic heat preservation.
Frit of 2. low heat
Because low heat conduction is led, get together the heat energy with very few save up of brick of heat preservation of light Mo Laishi, energy-saving in intermittent operation effect is apparent.
3. matter content is low
Have the oxide content such as alkali metal of low-down iron box, accordingly, fireproof degree tall; The higher volume that contain aluminium makes its still maintain good performance below reducing atmosphere.
Intensity of hot condition compression is high
Essence of 4. exterior dimension is accurate
Accelerate build by laying bricks or stones to build career, reduce fireproof mud to use an amount, assured the intensity of body of build by laying bricks or stones and stability, prolong the life of liner thereby. Can process special form.
Utility:
Can regard hot side as fireproof liner or other ammonia of the furnace of ethylene splitting decomposition of industry of oil of the thermal insulation back line of fireproof material, application Yu Shi, chemical industry, heating furnace tubal form, synthesis changes furnace, gas happening kiln of path of roller of kiln of type of shuttle of furnace, high temperature, channel kiln, pottery and porcelain.
Get together in production of brick of heat preservation of light Mo Laishi, eventually the exterior dimension of the product assures, mix except burden firing outside influencing factor, basically rely on profiling of neat semi-manufactured goods machinery to assure.
1, the action of additive
This additive is the compound additive that comprises by a variety of fireproof material, can promote what type reacts to undertake, in get together light Molaishi reachs very good steady volume action since each phase with heat preservation firing brick, happen a series of physico-chemical reaction, make Mo Laishi appearance.
2, burn lost property
Be used burn lost property to be polystyrene spherule and wooden pink. Polystyrene spherule is a hydrocarbon, firing hind can in light qualitative Molaishi bricky interior is formed inside the atmosphere hole wall of spherical and smooth globose air aperture and solid excel in. The weakness of pushball is, the sphere in pug is easy reunite, and cannot form pull pull, go against base substrate intensity consequently rise. The permission of pushball adds a capacity finite, get together to be reduced effectively density of brick of heat preservation of light Mo Laishi, and do not reduce base substrate intensity,
3, the action of the agent that decrease water
Get together of brick of heat preservation of light Mo Laishi shape the method is belonged to wet but model shapes, content of pug water portion is high, the systole that the base substrate in dry process produces is big, barren base is easy occurrence crackle and systole not all. Decrease the affiliation of water agent, the affiliation that reduced water effectively is measured, avoided the happening of afore-mentioned problems.
