冷库工程安全运行是每个投资者必须考虑的问题。制冷设备安全运行中，首要解决的就是设备安全问题。据不完全统计，在以往发生过的冷库安全事故中，大部分的事故是由于电源线路短路造成的。所以，如何选择好绝缘材料显得尤为重要。今天给大家介绍冷库工程中常用到的几类绝缘材料。
The safe operation of cold storage project is a problem that every investor must consider. In the safe operation of refrigeration equipment, the most important problem is the safety of equipment. According to incomplete statistics, in the past occurred in cold storage safety accidents, most of the accidents caused by short circuit power supply. Therefore, how to choose a good insulation material is particularly important. Today we introduce several kinds of insulation materials commonly used in cold storage project.
刚性绝缘材料：
Rigid insulation:
刚性绝缘材料采用聚氨酯泡沫在冷藏设施的结构。这种类型的绝缘层是很常见的，因为它的有效性。保温是有效的，因为使用的材料有足够的抗折和抗压强度，保持设备的运输和使用过程中的完整性。绝缘之间的内部衬垫和冷藏设施的外壳注入液体化学品的生产。化学反应，流动性和扩大，以形成绝缘。
Rigid insulation material using polyurethane foam in cold storage structure. This type of insulation is very common because of its effectiveness. Insulation is effective because the materials used are sufficiently resistant to bending and compressive strength to maintain the integrity of the equipment during transportation and use. The production of liquid chemicals into the enclosure between the inner liner and the refrigeration facility. Chemical reactions, mobility and expansion to form insulation.
面板绝缘：
Panel insulation:
塑料，玻璃或金属外壳，面板可以进行绝缘。玻璃外壳是首选，因为他们来传递热量的能力是5％，优于金属比塑料外壳，他们可以持续更长的时间。更好的保温玻璃，当玻璃是薄的，因为导热系数下降。该小组还可以承受的温度变化，因为超薄玻璃，它提供了灵活性。
Plastic, glass or metal shell, the panel can be insulated. The glass shell is preferred because they have the ability to transfer heat to 5%, superior to the metal over the plastic casing, and they can last longer. Better insulation glass, when the glass is thin, because the thermal conductivity decreased. The panel can also withstand the temperature changes because of the ultra-thin glass, which provides flexibility.
泡沫保温：
Foam insulation:
聚氨酯泡沫保温材料使用的发泡剂，在冷藏设施，形成绝缘。发泡剂有利于扩大和流动注入冰箱冷冻铸造化学品。最初，使用氯氟烃作为发泡剂，但他们被取代氟氯烃，因为对臭氧层的氟氯化碳的有害影响。氟氯烃的毒性低，可以安全使用。
Polyurethane foam insulation materials used in the foaming agent, in cold storage facilities, forming insulation. Blowing agent is beneficial to expand and flow into the refrigerator to freeze the casting chemicals. First, the use of CFCs as a foaming agent, but they replaced CFCs, because the harmful effects of CFCs to the ozone layer. Chlorofluorocarbons low toxicity, safe to use.
气体填充小组绝缘：
Gas filled insulation:
随着充气面板保温，绝缘板，充满气体，如氩气和氪低导热。气体绝缘板，以最大限度地减少传导，对流和辐射。充气面板绝缘，没有总的压力差，因此可以在不同大小和形状的塑造，以适应许多绝缘配置。
With pneumatic panel insulation, insulation board, full of gas, such as argon and krypton and low thermal conductivity. Gas insulated panels to minimize conduction, convection and radiation. Inflatable panel insulation, no total pressure difference, so can be molded in different sizes and shapes to fit many insulation configuration.
以上就是冷库的四种绝缘材料，大家可以在安装的时候，根据自己的需求，选择合适的绝缘材料，从而保证冷库的稳定运行。
These are the four kinds of insulation materials, we can in the installation, according to their own needs, choose the appropriate insulation material, so as to ensure the stable operation of cold storage.
