ການຈັດປະເພດຂອງ insulation refractories
If classified according to the use temperature, heat insulation refractory materials can be divided into 3 types:
①ວັດສະດຸ insulation ອຸນຫະພູມຕ່ໍາ, ຕ່ໍາກວ່າ 600 ℃;
②ວັດສະດຸ insulation ອຸນຫະພູມປານກາງ, 600 ~ 1200 ℃;
③ອຸນຫະພູມສູງອຸປະກອນການ insulation, ສູງກ່ວາ 1200 ℃.
From the perspective of bulk density, the bulk density of lightweight heat-insulating refractory materials is generally not greater than 1.3g/cm3, and the bulk density of commonly used light-weight heat-insulating refractory materials is 0.6~1.0g/cm3, if the bulk density is 0.3~0.4 g /cm3 or lower, it is called 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 Fibrous heat-insulating materials are cotton-like and fiber-like heat-insulating materials. Fibrous materials are easy to form porous structures. Therefore, fibrous thermal insulation materials are characterized by light weight, good thermal insulation performance, elasticity, and good sound absorption and shock resistance.

ຮູບແບບແລະສະຖານະການແຈກຢາຍແມ່ນແບ່ງອອກເປັນສາມປະເພດດັ່ງຕໍ່ໄປນີ້:
①Insulation materials in which the gas phase is the continuous phase and the solid phase is the dispersed phase;
②ວັດສະດຸ insulation ທີ່ໄລຍະແຂງແມ່ນໄລຍະຢ່າງຕໍ່ເນື່ອງແລະໄລຍະອາຍແກັສແມ່ນໄລຍະກະແຈກກະຈາຍ;
③ວັດສະດຸ insulation ທີ່ທັງສອງໄລຍະອາຍແກັສແລະໄລຍະແຂງແມ່ນໄລຍະຢ່າງຕໍ່ເນື່ອງ. ວິທີການຈັດປະເພດນີ້ແມ່ນສະດວກກວ່າໃນການວິເຄາະແລະສຶກສາອິດທິພົນຂອງໂຄງສ້າງອົງການຈັດຕັ້ງຕໍ່ການປະຕິບັດຂອງວັດສະດຸ insulation ຄວາມຮ້ອນ.
