Pag-uuri ng mga insulation refractory
Pag-uuri ng mga insulation refractory
If classified according to the use temperature, heat insulation refractory materials can be divided into 3 types:
① Mga materyales sa pagkakabukod ng mababang temperatura, mas mababa sa 600 ℃;
②Medium temperature insulation material, 600~1200℃;
③Mataas na temperatura pagkakabukod materyal, mas mataas kaysa sa 1200 ℃.
Mula sa pananaw ng bulk density, ang bulk density ng magaan na heat-insulating refractory na materyales ay karaniwang hindi hihigit sa 1.3g/cm3, at ang bulk density ng mga karaniwang ginagamit na light-weight heat-insulating refractory na materyales ay 0.6~1.0g/cm3, kung ang bulk density ay 0.3~0.4 g /cm3 o mas mababa, ito ay tinatawag na ultra-lightweight insulation material.
Insulating refractory materials can also be divided into:
①Powder and granular heat-insulating materials include powder-grain bulk materials that directly use refractory powder or granular materials as filling insulation layers without bonding agent, and powder-grain bulk light-weight amorphous heat-insulating refractory materials containing bonding agent. The powdery granular thermal insulation material is convenient to use and easy to construct. It can be called an effective thermal insulation layer for high-temperature kilns and equipment by filling and making on site.
②Stylish heat-insulating materials refer to heat-insulating materials with a certain shape with porous structure. Among them, brick-shaped products are the most common, so they are generally called light-weight heat-insulating bricks. Lightweight insulation bricks are characterized by stable performance, and are easy to use, transport and store.
③ Ang fibrous heat-insulating material ay parang cotton at fiber-like heat-insulating material. Ang mga hibla na materyales ay madaling bumuo ng mga buhaghag na istruktura. Samakatuwid, ang fibrous thermal insulation na materyales ay nailalarawan sa pamamagitan ng magaan na timbang, mahusay na pagganap ng thermal insulation, pagkalastiko, at mahusay na pagsipsip ng tunog at shock resistance.
④Composite thermal insulation materials mainly refer to thermal insulation materials made of fiber materials and other materials, such as thermal insulation panels, thermal insulation coatings and other thermal insulation materials.
Ang mode at katayuan ng pamamahagi ay nahahati sa sumusunod na tatlong kategorya:
①Insulation materials kung saan ang gas phase ay ang tuloy-tuloy na phase at ang solid phase ay ang dispersed phase;
②Insulation materials in which the solid phase is the continuous phase and the gas phase is the dispersed phase;
③Insulation materials kung saan ang gas phase at solid phase ay tuluy-tuloy na phase. Ang paraan ng pag-uuri na ito ay mas maginhawa upang pag-aralan at pag-aralan ang impluwensya ng istraktura ng organisasyon sa pagganap ng mga materyales sa thermal insulation.
