In Ji'nan, container insulation material is used as high as possible. Thermal insulation material with small thermal conductivity is adopted to reduce the thickness of fresh-keeping temperature and improve the indoor application area. Classification of Ji'nan resident container thermal insulation materials:

1、按材質可分為無機保溫隔熱材料、有機保溫隔熱材料和金屬絕熱材料3大類；

1. According to the material, it can be divided into 3 kinds: inorganic thermal insulation material, organic heat insulation material and metal insulation material.

2、按形態又可分為纖維狀保溫隔熱材料、多孔狀保溫隔熱材料、層狀保溫隔熱材料；

2, according to the form, it can be divided into fibrous heat insulation material, multi hole heat insulation material and layered insulation material.

3、按材料的耐溫范圍保溫隔熱材料可分為，低溫保溫隔熱材料、中溫保溫隔熱材料、高溫保溫隔熱材料。所以在選擇保溫隔熱材料的耐溫性能必須符合使用情況。

3, the thermal insulation material according to the temperature range of the material can be divided into low temperature insulation material, medium temperature insulation material, high temperature insulation material. Therefore, the temperature resistance of the thermal insulation material must be in accordance with the use.

保溫隔熱材料的性能取決于材料的熱導系數，熱導系數愈小，其保溫隔熱的性能則愈好。保溫隔熱材料的熱導系數與其成分、表觀密度、內部結構以及傳熱時的平均溫度和材料的含水率有關，隔熱系統中隔熱層的厚度往往有個大值，使用所選保溫隔熱材料所需的隔熱層厚度必須在大值以內。

The performance of thermal insulation material depends on the thermal conductivity of the material, the smaller the thermal conductivity, the better its thermal insulation performance. The thermal conductivity coefficient and its composition, rate of thermal insulation material with water surface average temperature and material density, internal structure and heat transfer of the heat insulation layer, the thickness of insulation systems tend to have a maximum thickness of insulating layer using the selected insulation materials required must be at the maximum value.

根據化學特性，不同類型的保溫隔熱材料有著不同的化學特性，要選擇符合使用環境的材料才好。

According to the chemical properties, different types of thermal insulation materials have different chemical properties. It is best to choose materials that meet the use environment.
