硬質(zhì)聚氨酯組合料分爲(wèi)異氰酸酯和組合聚醚兩個(gè)組份:俗稱黑料和白料。兩者按比例攪拌混合后發(fā)作聚合反響，生成具有閉孔構(gòu)造的聚氨酯硬質(zhì)泡沫塑料，是一種理想的無機(jī)質(zhì)高溫隔熱資料，具有導(dǎo)熱系數(shù)小，防震，順應(yīng)性強(qiáng)，既可預(yù)制成型，也可現(xiàn)場噴涂式澆注成型、普遍使用于煉油廠、化工廠、乙烯化工、冷庫、單制冷空調(diào)、冰箱和修建業(yè)保溫隔熱。隨著在修建范疇的推行，聚氨脂發(fā)泡保溫體系以其良好的保溫功能和施工迅速，功能牢靠等特點(diǎn)已在保溫范疇大規(guī)模使用。 聚氨酯組合聚醚和異氰酸酯的貯存與平安操作
Rigid polyurethane composite material is divided into two components: isocyanate and polyether: commonly known as black and white. The rigid polyurethane foam with closed-cell structure is an ideal inorganic material for high temperature insulation. It has low thermal conductivity, energy-saving, shock-proof and strong compliance. It can be pre-fabricated or sprayed on-site pouring moulding. It is widely used in refineries, chemical plants, ethylene chemical industry, cold storage, single refrigeration and air-conditioning, etc. Refrigerator and construction industry heat preservation and insulation. With the implementation of energy-saving construction, polyurethane foam insulation system has been widely used in the field of thermal insulation because of its good thermal insulation function, rapid construction and reliable function. Storage and Safe Operation of Polyurethane Composite Polyether and Isocyanate
一、貯存 異氰酸酯（俗稱黑料）與組合聚醚（俗稱白料）的貯存必需是在密封的容器內(nèi),隔絕空氣、避免吸潮。 異氰酸酯與組合聚醚料桶不應(yīng)在陽光下暴曬，必需遠(yuǎn)離熱源，放置涼枯燥處，料桶假如直立放置時(shí)，桶蓋上不得積水!假如整桶料不能一次用完，就必需在每次運(yùn)用后立刻蓋緊桶蓋，避免水汽、雜質(zhì)進(jìn)入桶內(nèi)而影響質(zhì)量。
1. Storage of isocyanate (commonly known as black material) and composite polyether (commonly known as white material) must be in a sealed container to isolate air and avoid moisture absorption. Isocyanate and composite polyether barrels should not be exposed to sunlight, they must be far away from heat sources and placed in cool and dry places. If the barrel is placed upright, the barrel cover should not accumulate water. If the whole barrel material can not be used up at once, the barrel cover must be tightened immediately after each use to avoid water vapor and impurities entering the barrel and affecting the quality.
假如運(yùn)用兩個(gè)以上牌號組合聚醚時(shí)，應(yīng)分牌號堆放，并有分明標(biāo)志。參加普通阻燃劑的組合聚醚寄存工夫不應(yīng)太長，必需當(dāng)天配制當(dāng)天運(yùn)用，否則易形成蛻變影響發(fā)泡質(zhì)量。 聚氨酯直埋保溫管近期銷量走勢 隨著各類不同的直埋保溫管開端呈現(xiàn)在市場中當(dāng)前，關(guān)于這樣的一種技術(shù)的創(chuàng)新還是具有很大的作用的。怎樣樣讓這種適用性表現(xiàn)出來恩？關(guān)鍵就是在于社會效益和經(jīng)濟(jì)效益，由于各種不同的保溫效果也是在這個(gè)進(jìn)程中可以更好的表現(xiàn)出來的。因而作爲(wèi)供熱進(jìn)程中的一種無效措施，進(jìn)入到市場中當(dāng)前，逐步的關(guān)于這樣的供熱管道也是具有了新的終點(diǎn)。
If two or more brands are used to combine polyethers, they should be stacked separately and clearly marked. The storage time of the combined polyether with common flame retardant should not be too long. It must be used on the same day when it is prepared, otherwise it will easily degenerate and affect the foaming quality. The recent sales trend of polyurethane direct-buried insulating pipes has appeared in the market with the beginning of various types of direct-buried insulating pipes. The innovation of such a technology still plays a very important role. How to show this applicability? The key lies in the social and economic benefits, because different thermal insulation effects can be better displayed in this process. Therefore, as an ineffective measure in the process of heating and energy saving, entering the market at present, gradually on such heating pipeline also has a new end point.
聚氨酯直埋保溫管近期銷量走勢 針對直埋保溫管的劣勢，次要就是在于需求創(chuàng)新，更好的關(guān)于這樣的功能、質(zhì)量、以及相關(guān)的劣勢條件停止不時(shí)的開展，這樣在運(yùn)用進(jìn)程中，才干夠起到更好的效果，也是進(jìn)入到市場中當(dāng)前，逐步被認(rèn)可的一種資料。 更好的讓直埋保溫管進(jìn)入到很多修建行業(yè)中，那麼這樣的一項(xiàng)技術(shù)還是需求不時(shí)的完善和開展，更好的表現(xiàn)這樣的用處。
The recent sales trend of polyurethane direct-buried insulating pipes is aimed at the disadvantage of direct-buried insulating pipes. Secondly, the demand innovation is needed. Better performance, quality and related disadvantage conditions are stopped from time to time. In this way, in the process of application, it can play a better effect, and it is also a kind of information that is gradually recognized in the Chinese market. Better let directly buried insulation pipe into many construction industries, then such a technology or need to be improved and carried out from time to time, better performance of such use.
