聚氨酯管托
一、簡介聚氨酯管托，即高密度聚氨酯保冷管托，系由異氰酸酯與聚醚為主原料，再加上發泡劑、觸媒和阻燃劑，經高速攪拌混合反應生成的具有塑膠、橡膠和軟木特性的發泡聚合體。泡體是由成千上萬極微小均勻的獨立細胞組成，呈立體蜂窩式的結構。其熱傳導率低、抗壓強度高、吸水率低，有瀝青木製品及其他類襯墊物難以比擬的優良性質，是深冷管道管托、鞍座及低溫設備墊塊的理想材料。在國內及歐美國家用於石油化工基地、LNG液化氣廠、冷鏈基地及中央空調系統之管托、支吊架及墊塊等。
High density PU pipe support is a new kind of foaming polymer with the features of plastic, rubber and softwood. It is created through high speed stirring with the main raw material of isocyanate and polyether added with vesicant, catalyst or flame retardants. The foaming body is a structure like a three-dimensional honeycomb, which is made up of ten thousands of isolated cells. It has low thermal conductivity, high compressive strength, and low water adsorption, it has excellent properties which asphalt-wood products and other pads difficult to compare. It’s ideal material for cold pipe supports and equipment pads. It is used as pipe supports, cradles and equipment pads in petrochemical industry, LNG liquefied gas factory, cold-chain base and central air conditioner both in domestic and foreign.
