Advantages and disadvantages of traditional thermal insulation material "glass wool"

As a common thermal insulation material, glass fiber cotton is an inorganic material with relatively good performance. This thermal insulation material is made of glass balls or waste glass through high temperature, wire drawing, winding and other steps. The diameter of the monofilament of the finished glass wool thermal insulation material is several microns to twenty microns, which is only one twentieth to one fifth of that of a hair filament. Usually, this kind of thermal insulation material has good thermal insulation, sound absorption, long fiber, tensile and compressive properties. , used for building air conditioning and home insulation.

Advantages of glass wool thermal insulation material:

1, good thermal insulation. Glass fiber cotton has numerous fine pores, irregular fiber arrangement and thermal conductivity of 0.03w/cm.k, which is an excellent thermal insulation material.

2. It is nonflammable. Glass fiber cotton does not burn, deform or embrittle, can withstand high temperature of 700 degrees, and its combustion performance reaches A 1 level;

3, environmental protection and non-toxic. Because glass fiber cotton does not add any binder in the manufacturing process, it has no smell, and it will not emit toxic and pungent smoke and smell when it encounters high temperature;

4. High insulation. Because the raw material used in glass fiber cotton is glass, which is not conductive, it has quite high insulation;

5, corrosion resistance. Glass fiber is not afraid of strong acid and has strong corrosion resistance, and its functional characteristics will not be reduced even after long-term use;

6. Good responsiveness. Glass fiber contains numerous fixed air pockets, has excellent resilience, is not afraid of any impact and vibration, and its tensile strength is above 1.0kg.

7, do not absorb water. The moisture absorption rate of glass fiber is usually close to zero, so there is no need to worry about wet cracking caused by water absorption and expansion.

Disadvantages of glass wool thermal insulation material;

1, the raw material is glass, but it also has the disadvantage of being fragile and easy to break;

2, poor wear resistance. Long-term use can easily lead to damage. Once a sharp object scratches the surface, it will cause irreparable wear.
