Light qualitative tall aluminous brick is heat preservation brick, rate of its heat conduction is lower, its coefficient of thermal conductivity and system are secret about, system is secret: 03. - 1.2g/cm3, 25 ℃ of ± of W/m.k(350 of coefficient of thermal conductivity) : 0.25-0.45. Specific heat capacity: The material of unit quality, temperature is elevatory (or reduce) 1 ℃ place is absorbed (or give off) quantity of heat.
Specific heat capacity is to show the even material of certain amount is in the quantity of heat that 1K place warms up to need below the situation that does not produce to change to change with chemistry. If be 1 rub Er material, the quantity of heat of need is rub Er thermal capacitance. Specific heat capacity is larger, the absorption of heat of the object or medicinal powder heat energy force is more powerful.
Constant depressive rub Cp of Er thermal capacitance calls constant voltage rub Er thermal capacitance. Below the condition that decide a look rub Cv of Er thermal capacitance calls calm look rub Er thermal capacitance. Normally constant voltage rub the relation of Er thermal capacitance and temperature is polynomial relation. Specific heat capacity is to point to in often press next heating the quantity of heat that 1kg stock makes its temperature lifts 1 ℃ place needs (the unit is KJ) . Specific heat capacity is unit quality (the quantity of heat that the material of 1g or 1Kg) lifts in temperature the place when 1k is absorbed, also call quality thermal capacitance, the unit is J/(g · K) . The thermal capacity of light qualitative tall aluminous brick depends on its chemistry composition and temperature, affect body of heater not only heat and cooling rate, also have important sense in tall aluminous brick.
Specific heat capacity and what are concerned? The sort of specific heat capacity and material and condition are concerned, it is the macroscopical expression of microcosmic property. 1. In condition changeless circumstance falls, we think roughly, the energy that temperature lifts place is brought is not to be used overcome the force between element or ion to bilge in heat cold shrink the work that does in the process, and the active degree that what temperature measures below this kind of circumstance is element or ion, so the specific heat capacity of some kind of material adds this kind of substance namely every unit member or the energy that ionic and average active needs. 2, allergy happening is in during, if melt, sublimate, plasma. , this needs alone consideration only. Pure object is in decay process: Infinite. The reason is abnormal process be advance gradually is not the instant, also conduct a principle to concern with heat.
The copper of specific heat capacity of common material: ) of ℃ of 0.39 × 103J/(kg · , iron: ℃ of 0.46 × 103J/(kg · ) aluminous: ) of ℃ of · of 0.88 × 103 J/(kg, water: ) of ℃ of 4.2 × 103J/(kg · , air: ) of ℃ of 1 × 103J/(kg · , mercuric: ℃ of 0.14 × 103J/(kg · ) alcohol: ℃ of 2.4 × 103J/(kg · ) kerosene: ℃ of 2.1 × 103J/(kg · ) castor oil: ℃ of 1.8 × 103J/(kg · ) arenaceous stone: ℃ of 0.29 × 103J/(kg · ) dry cement: ℃ of 0.84 × 103J/(kg · ) ice: ℃ of 2.1 × 103J/(kg · ) lead: ℃ of 0.13 × 103J/(kg · )
Thermal conductance thermal conductance (weigh coefficient of thermal conductivity again) it is to show gradient of immanent unit temperature issues unit time to pass the quantity of heat that data unit area delivers along thermal current direction. Fireproof material thermal conductance is OK according to national level GB/T 5990, method of experiment of thermal conductance of 2006 fireproof material (hot line law) or YB/T 4130 of black metallurgy standard, method of experiment of thermal conductance of 2005 fireproof material (discharge flat law) undertake determining. One of main hot physics function that the thermal conductance of fireproof material is fireproof material, it is indispensable in the design of facilities of expensive tepid work important data, also be the factor of very main a consideration that chooses fireproof material. The chemical part of fireproof material is more complex, its thermal conductance reduces the material with complex structure of crystal of more apparent; , low also; is in thermal conductance certain temperature less than, porosity heals big, thermal conductance heals low.
Alumina is fireproof the thermal conductance of data products (7.2kcal/m.h. ℃ ) , specific heat capacity (0.205kcal/kg. ℃ ) , density > 3.9g/ ㎝ 3.
How much is rate of heat conduction of light qualitative tall aluminous brick? Light qualitative tall aluminous brick 25 ℃ of ± of W/m.k(350 of coefficient of thermal conductivity) : 0.25-0.45. Specific heat capacity: The material of unit quality, temperature is elevatory (or reduce) 1 ℃ place is absorbed (or give off) quantity of heat.
Fireproof material occurrence craze, fall off, easy how to wear away to do?
