The physical function of fireproof material is in to its high temperature environment is used mediumly crucial. It is the function of a few crucial physics of fireproof material below:
1.Fireproof degree (Refractoriness) definition: Fireproof spending is to show fireproof material can issue the ability that maintains its physics and chemical stability in high temperature, express normally with the melting point of material or softening point. Importance: Fireproof degree decided rate of material difficult dissolve. In applying actually, fireproof degree taller, the temperature range with applicable material is wider.
2.Thermal conductance (Thermal Conductivity) definition: Thermal conductance is to show material conducts caloric ability, the unit is W/(m · K) . Importance: The material of low thermal conductance is used at heat preservation and heat insolation normally, in order to reduce hot loss. The material of high fever conductance applies to the application that need conducts heat quickly.
3.Hot coefficient of expansion (Thermal Expansion Coefficient) definition: Hot coefficient of expansion is to show material is heating the bulk in the process or the degree that dimension changes, the unit is 1/K. Importance: Because temperature change is caused,inferior hot coefficient of expansion can decrease be out of shape and the thermal shock influence to material.
4.Heatproof shake sex (Thermal Shock Resistance) definition: Heatproof shake sex is to show material is when the temperature change with sharp experience, can resist crackle and cracked ability. Importance: Good heatproof shake performance prolongs the service life of fireproof material quite, in the temperature environment that changing often especially.
5.Compressive strength (Compressive Strength) definition: Compressive strength is to show material is below press press circumstance can pressure of susceptive upper limit, the unit is MPa. Importance: The data of high compressive strength can support high load capacity, decrease be out of shape and burst, ensure structural stability.
6.Fight lose strength (Flexural Strength) definition: Fight losing strength is to show material is in when bending can stress of susceptive upper limit, the unit is MPa. Importance: The data that Gao Kang loses strength can resist stress bends in what the likelihood in applying actually encounters, enhance the tenacity of material.
7.Fight abrasiveness (Abrasion Resistance) definition: Fighting abrasiveness is the ability that points to material to resistance wears away and be eroded. Importance: In the equipment that handles grain shape or fluidity material, fight abrasiveness to be opposite the service life that prolongs fireproof material is crucial.
8.Fight chemistry caustic (Chemical Resistance) definition: Fight chemistry caustic it is the ability that shows material resists chemical material is eroded. Importance: Fight chemistry goodly to corrode function to protect material to avoid quite suffer slag, acerbity, alkaline wait for chemical material erode.
9.Density (Density) definition: Density is the rate of the quality of material and bulk, the unit is G/cm³ . Importance: Density affects the intensity of fireproof material and wear. High density material has higher mechanical intensity and fireproof property normally, but may bring about taller thermal conductance.
10.Hole leads (Porosity) definition: Hole leads the rate that is bulk of the hole in material and total volume, express with per cent normally. Importance: Inferior hole rate means higher intensity and fireproof sex normally, and the thermal conductance that higher hole rate can reduce material, improve adiabatic performance.
11.Stomatic bulk (Pore Volume) definition: Stomatic bulk is the scale that shows the hole in material takes total volume, the thermal conductance that affects data and impervious appear a gender. Importance: Control stomatic bulk to be able to adjust the heat preservation sex of fireproof material and sealing.
12.Fight oxidisability (Oxidation Resistance) definition: Fighting oxidisability is to show material oxidizes in high temperature the stability in the environment. Importance: Fight oxidisability goodly to be able to prolong the service life of material, because oxidize,prevent to react and bring about function to drop.
The physical function that summarizes fireproof data decided his the applicability in high temperature and harsh environment. Understand these function to be able to help the fireproof stuff with right choice, optimize its function in applying actually, in order to satisfy specific working requirement and requirement.
