The products of Ji'nan insulation pipe company adopt isocyanate, which is formed by three kinds of quantitative catalyst and polyether reaction, forming foam material, and its cooling degree is better than that of common pipe material. In recent years, the performance of some new types of pipes and foam glass has been widely praised by some people for being consistent with the market price. But there are also some enterprises using these two materials in the cold industry. But this is not the case. We must believe that all kinds of materials for the survival of the fittest must have its development. If the performance and use are the same, then all cold insulation manufacturers can only do a good job?

　　今天，每个人都需要了解保温管和泡沫玻璃之间的比较，每个都有它的优点和缺点型聚氨酯管道产品，密度轻，耐低温，导热系数低，保温效果好，具有一定的柔软性，能承受管道的轻微振动，一般为45元/m3。预制聚氨酯保温管应采用导热系数低的保温材料;不受潮变质，耐热性好，不腐蚀金属，重量轻，空隙大;具有一定的机械强度，不会受到外力的破坏;加工简单，成本低等。常用的保温材料有:膨胀珍珠岩及其制品、玻璃棉及其制品、岩棉制品、微孔硅酸钙、硅酸铝纤维制品、泡沫塑料、泡沫石棉等。

　　Today, everyone needs to understand the comparison between insulation tube and foam glass. Each has its advantages and disadvantages of polyurethane pipe products, which are light in density, low in temperature, low in thermal conductivity, good in thermal insulation, flexible and can withstand slight vibration of pipes. The price is generally 45 yuan /m3. The prefabricated polyurethane heat preservation pipe shall be made of heat preservation material with low thermal conductivity; it shall not be affected by dampness, good heat resistance, metal corrosion, light weight and large gap; it shall have certain mechanical strength and not be damaged by external force; it shall be simple in processing and low in cost. Commonly used thermal insulation materials are expanded perlite and its products, glass wool and its products, rock wool products, microporous calcium silicate, aluminum silicate fiber products, foam plastics, foam asbestos and so on.

　　聚氨酯直埋保温管适用于室内外管道、集中供热管道、空调管道、化工、医药等工业管道的保温与冷却工程。聚氨酯泡沫保温管聚氨酯合成材料的概述,30年代诞生以来,一直作为一种优良的隔热材料,得到了快速发展,其应用范围也越来越广泛,由于其施工简单和显著的防腐效果,广泛用于各种加热、制冷、油、蒸汽等各种各样的管道。大量供热、制冷、供油、蒸汽等管道。缺点是:吸水率差，火级只能达到B1级。泡沫玻璃耐高温、不吸水、不老化、不收缩、不燃烧，缺点是相对较高，导热系数高于PIR，故应增加厚度。

　　Polyurethane direct buried heat preservation pipe is suitable for heat preservation and cooling of indoor and outdoor pipes, central heating pipes, central air conditioning pipes, chemical, pharmaceutical and other industrial pipes. Polyurethane foam insulation tube polyurethane synthetic materials overview, since its inception in 30s, has been a good insulation material, has been developing rapidly, and its application scope is more and more widely. Because of its simple construction and remarkable energy saving and anti-corrosion effect, it is widely used in all kinds of pipes such as heating, refrigeration, oil, steam and so on. A large number of heating, cooling, oil supply, steam and other pipes. Disadvantages: poor water absorption, fire can only reach Class B1. Foam glass has high temperature resistance, no water absorption, no aging, no shrinkage and no combustion. The disadvantage is that the price is relatively high and the thermal conductivity is higher than PIR, so the thickness should be increased.

　　当我们比较这两种冷绝缘材料时，我们试图考虑它们各自的实际情况。预制聚氨酯保温管应采用导热系数低的保温材料;不受潮变质，耐热性好，不腐蚀金属，重量轻，空隙大;具有一定的机械强度，不会受到外力的破坏;加工简单，成本低等。常用的保温材料有:膨胀珍珠岩及其制品、玻璃棉及其制品、岩棉制品、微孔硅酸钙、硅酸铝纤维制品、泡沫塑料、泡沫石棉等。选择一个技术水平好的，合理的厂家，质量也是有保证的，再加上适合自己的产品，就是一次成功的采购。现在，这两种理想的材料，聚氨酯管材厂家经常用来组合，里面一层PIR，外面一层泡沫玻璃，如果我们需要性能更好的产品，我们也可以考虑这种复合材料。

　　When we compare the two kinds of cold insulation materials, we try to consider their actual situation. The prefabricated polyurethane heat preservation pipe shall be made of heat preservation material with low thermal conductivity; it shall not be affected by moisture, has good heat resistance, does not corrode metal, is light in weight and has large space; it shall have certain mechanical strength and will not be damaged by external forces; it shall be simple in processing and low in cost. Commonly used thermal insulation materials are expanded perlite and its products, glass wool and its products, rock wool products, microporous calcium silicate, aluminum silicate fiber products, foam plastics, foam asbestos and so on. Choosing a manufacturer with good technology and reasonable price, with guaranteed quality, plus products suitable for oneself, is a successful purchase. Now, these two ideal materials, polyurethane pipe manufacturers are often used to combine, one layer of PIR, a layer of foam glass outside, if we need better performance products, we can also consider this composite material.
