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，每個人都需要了解保溫管和泡沫玻璃之間的比較，每個都有它的優(yōu)點(diǎn)和缺點(diǎn)型聚氨酯管道產(chǎn)品，密度輕，耐低溫，導(dǎo)熱系數(shù)低，保溫效果好，具有一定的柔軟性，能承受管道的輕微振動，一般為45元/m3。預(yù)制聚氨酯保溫管應(yīng)采用導(dǎo)熱系數(shù)低的保溫材料;不受潮變質(zhì)，耐熱性好，不腐蝕金屬，重量輕，空隙大;具有一定的機(jī)械強(qiáng)度，不會受到外力的破壞;加工簡單，成本低等。常用的保溫材料有:膨脹珍珠巖及其制品、玻璃棉及其制品、巖棉制品、微孔硅酸鈣、硅酸鋁纖維制品、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.

　　聚氨酯直埋保溫管適用于室內(nèi)外管道、集中供熱管道、空調(diào)管道、化工、醫(yī)藥等工業(yè)管道的保溫與冷卻工程。聚氨酯泡沫保溫管聚氨酯合成材料的概述,30年代誕生以來,一直作為一種優(yōu)良的隔熱材料,得到了快速發(fā)展,其應(yīng)用范圍也越來越廣泛,由于其施工簡單和顯著的防腐效果,廣泛用于各種加熱、制冷、油、蒸汽等各種各樣的管道。大量供熱、制冷、供油、蒸汽等管道。缺點(diǎn)是:吸水率差，火級只能達(dá)到B1級。泡沫玻璃耐高溫、不吸水、不老化、不收縮、不燃燒，缺點(diǎn)是相對較高，導(dǎo)熱系數(shù)高于PIR，故應(yīng)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.

　　當(dāng)我們比較這兩種冷絕緣材料時(shí)，我們試圖考慮它們各自的實(shí)際情況。預(yù)制聚氨酯保溫管應(yīng)采用導(dǎo)熱系數(shù)低的保溫材料;不受潮變質(zhì)，耐熱性好，不腐蝕金屬，重量輕，空隙大;具有一定的機(jī)械強(qiáng)度，不會受到外力的破壞;加工簡單，成本低等。常用的保溫材料有:膨脹珍珠巖及其制品、玻璃棉及其制品、巖棉制品、微孔硅酸鈣、硅酸鋁纖維制品、泡沫塑料、泡沫石棉等。選擇一個技術(shù)水平好的，合理的廠家，質(zhì)量也是有保證的，再加上適合自己的產(chǎn)品，就是一次成功的采購。現(xiàn)在，這兩種理想的材料，聚氨酯管材廠家經(jīng)常用來組合，里面一層PIR，外面一層泡沫玻璃，如果我們需要性能更好的產(chǎn)品，我們也可以考慮這種復(fù)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.
