Well-known, frit kiln is glass produces a proprietor of an enterprise to want waste time can equipment, the quantity of heat that enters vitreous frit pit has 30% about the left and right sides is used up come loose in kiln body on heat, wasted the sources of energy not only, and worsened production operates an environment. Have complete thermal insulation to vitreous frit kiln, can raise blaze temperature not only, raise fused rate, improve glassy capacity, reduce specific power consumption, managing fuel, and can improve working environment, reduce cost, managing capital. Undertake to frit kiln complete heat preservation can raise blaze temperature 20%-30% , managing fuel 15%~20% . Because this has dispute of complete heat preservation to kiln body,often want. The sort that vitreous kiln uses heat-insulating material is very much, if clay pledges,firebrick of adiabatic firebrick, silicon qualitative heat insolation, diatomite brick and heat preservation pound dozen of makings to wait.
Vitreous kiln uses heat preservation brick to differ with heat preservation brick and building
Vitreous kiln belongs to a kind of firebrick with heat preservation brick, it is the product of brick of fireproof heat preservation with inferior content of a kind of alumina, it and brick of common building heat preservation are distinguishing. All sorts of industry furnace of the temperature limits that pledges firebrick of heat preservation heat insolation applies to ℃ of 900 ℃ ~1650 gently heat up face lining material. Be like: Annealing furnace, carbonization furnace, answer burner, oil refining heating furnace, splitting decomposition furnace, roller path kiln, channel kiln. Spend before its characteristic is thermal capacitance of namely heat conduction rate, ground, tall, good, acid-proof alkaline atmosphere corrodes heatproof shake function wait for a characteristic.
And the building uses heat preservation brick namely brick of housetop heat insolation (heat preservation brick) it is heat preservation of a kind of collect and mask the roofing at an organic whole builds product with horniness, the efficient insulation material that uses certain ply, epispastic get together benzene board (or crowded model get together benzene board) with material of facing of mortar of special type cement with expertise one-time compound and into. Planar dimension is 300mm X 300mm commonly, thick left and right sides of 40 one 45mm. So a lot of clients are in brick of advisory heat preservation when think heat preservation brick is the building uses heat preservation brick by accident, not only there is very big difference on function, and both the price between also differs a lot of.
Vitreous frit kiln is fireproof material function
(1) organizes a structure
Fireproof material is by solid photograph (include crystallization and vitreous appearance) the blame that with air hole two parts form all plastid. The macrostructure structure feature of goods is the main factor that affects its high temperature to use property.
① porosity
In fireproof material, often a lot of size differ, the stoma with differ appearance. Call open pore with what atmosphere is interlinked (also call apparent pore) , call perforatively each other among them even blowhole, do not call closed pore with what atmosphere is interlinked. Reflect the compact rate of fireproof material normally with porosity, namely the percentage that the stomatic bulk in the brick holds total volume.
Porosity is the basic technology index of fireproof material, it affects each performance of refractory products almost. Porosity is smaller, of fireproof material be able to bear or endure aggressivity can be better, structural intensity is higher. Porosity is taller, the thermal conductance of material is lower.
② bulk density
Bulk density is volume of fireproof data unit (the total volume that contains air hole inside) has quality. It reflected the compact rate of refractory products intuitionisticly, it is the main index that measures level of quality of compact and fireproof material, refractory product. Generally speaking, bulk density is higher, porosity is smaller, a series of performance such as temperature of bate of loading of intensity, high temperature are better.
③ true density
True density is to show the quality of poriferous body material is as true as its bulk (do not contain air hole inside) than. True bulk is the bulk of material of the solid in pointing to poriferous body. The size that its are worth and send density, porosity to have nothing to do, and concern with the chemical and mineral composition of fireproof material.
(2) heat property
① heat is expansile
When fireproof material heats, bulk calls heat along with the lift and expands property of temperature expansile. Normally with linear expansion coefficient or body coefficient of expansion expresses.
When using fireproof data, take its seriously very heat is expansile, the characteristic obligate that should expand according to the be heated of fireproof material in frit kiln structure expands seam, the be heated that should press fireproof material when ignition bakes kiln expands the circumstance is made warm up reasonably curve and use adjust brace to wait want measure.
② thermal conductivity
Thermal conductivity represents the bulk of ability of fireproof material heat conduction, express with thermal conductance. Alleged thermal conductance is to show in unit temperature gradient falls, carry the thermal current rate of data unit area. It basically depends on the chemical composition of material and constituent structure.
③ thermal capacity
Thermal capacity weighs specific heat capacity again, point to in often press below, heat 1kg fireproof material makes warm up the quantity of heat that 1 ℃ needs. Warm up in design and control frit kiln, important sense is had when ability of accumulation of heat.
Buy vitreous frit kiln to use fireproof data, recommend Zhengzhou flourish to fill kiln furnace fireproof data limited company, home produces manufacturer high qualitily, complete order form quickly.
