इन्सुलेशन रेफ्रेक्ट्रीजचे वर्गीकरण

If classified according to the use temperature, heat insulation refractory materials can be divided into 3 types:

① कमी-तापमान इन्सुलेशन सामग्री, 600℃ पेक्षा कमी;

②मध्यम तापमान इन्सुलेशन सामग्री, 600~1200℃;

③उच्च तापमान इन्सुलेशन सामग्री, 1200℃ पेक्षा जास्त.

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 तंतुमय उष्णता-इन्सुलेट सामग्री कापसासारखी आणि फायबरसारखी उष्णता-इन्सुलेट सामग्री असते. तंतुमय पदार्थ सच्छिद्र संरचना तयार करणे सोपे आहे. म्हणून, तंतुमय थर्मल इन्सुलेशन सामग्री हलके वजन, चांगली थर्मल इन्सुलेशन कार्यक्षमता, लवचिकता आणि चांगले आवाज शोषण आणि शॉक प्रतिरोध द्वारे वैशिष्ट्यीकृत आहे.

④संमिश्र थर्मल इन्सुलेशन सामग्री प्रामुख्याने फायबर सामग्री आणि इतर सामग्रीपासून बनवलेल्या थर्मल इन्सुलेशन सामग्रीचा संदर्भ देते, जसे की थर्मल इन्सुलेशन पॅनेल, थर्मल इन्सुलेशन कोटिंग्स आणि इतर थर्मल इन्सुलेशन सामग्री.

The mode and distribution status are divided into the following three categories:

①इन्सुलेशन सामग्री ज्यामध्ये गॅस फेज हा अखंड टप्पा असतो आणि घन टप्पा हा विखुरलेला टप्पा असतो;

②इन्सुलेशन सामग्री ज्यामध्ये घन टप्पा हा सततचा टप्पा असतो आणि गॅस फेज हा विखुरलेला टप्पा असतो;

③Insulation materials in which both the gas phase and the solid phase are continuous phases. This classification method is more convenient to analyze and study the influence of organizational structure on the performance of thermal insulation materials.
