Fɛn jumɛnw de ye thermal insulation effect ye cotton na .

With the development of people's economy and energy, the technical level of materials and energy has also reached a rapid development in recent years, and there are many types of thermal insulation materials, which are divided into porous and heat-reflective according to the material. Porous mainly uses pores to achieve the effect of thermal insulation, such as foam and fiber. The main part of heat reflection itself has a high reflectivity, which can reflect heat such as gold, silver, nickel, etc. Fɛnba jumɛnw de bɛ nɔ bila insulation na?
