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、按材质可分为无机保温隔热材料、有机保温隔热材料和金属绝热材料3大类；

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、按形态又可分为纤维状保温隔热材料、多孔状保温隔热材料、层状保温隔热材料；

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

3、按材料的耐温范围保温隔热材料可分为，低温保温隔热材料、中温保温隔热材料、高温保温隔热材料。所以在选择保温隔热材料的耐温性能必须符合使用情况。

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.

保温隔热材料的性能取决于材料的热导系数，热导系数愈小，其保温隔热的性能则愈好。保温隔热材料的热导系数与其成分、表观密度、内部结构以及传热时的平均温度和材料的含水率有关，隔热系统中隔热层的厚度往往有个大值，使用所选保温隔热材料所需的隔热层厚度必须在大值以内。

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.

根据化学特性，不同类型的保温隔热材料有着不同的化学特性，要选择符合使用环境的材料才好。

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.
