又稱絕緣膠墊,,,絕緣墊,絕緣墊片,,,絕緣毯,Insulating pad,Insulation pad。主要應用于變電站、發(fā)電廠、配電房、試驗室以及野外帶電作業(yè)等。
層壓也叫,霧化 ,Matt Membrane,Matt from the film, TPX啞光,啞光分離膜,啞光,啞光保護膜,啞光,磨砂,亞光膜,啞光膜,TPX消光膜,絕緣膠墊層壓,絕緣墊層壓,絕緣墊片層壓,絕緣毯層壓;絕緣板因為層壓的時間較長,一般每次壓合需三到六個小時,所以要求絕緣板層壓較好的耐溫性,抗老化性能,且壓合后能夠方便地與絕緣板分離,不能有碎片和殘留現(xiàn)象發(fā)生。
絕緣板層壓主要用于變電站、發(fā)電廠、配電房、試驗室以及野外帶電作業(yè)等所使用到的絕緣板層壓時緩沖。絕緣板層壓又叫絕緣膠墊層壓、絕緣墊層壓、BENCH絕緣墊片層壓、絕緣毯層壓。專業(yè)為客戶提供各種規(guī)格優(yōu)質(zhì)絕緣板層壓,絕緣板層壓的常用厚度有12μm,15μm,18μm,20μm,22μm,23μm,25μm,28μm,30μm,32μm,33μm,35μm,36μm,38μm,50μm,75μm,100μm等。
絕緣板壓合一般采用工藝,也就是平板硫化機壓合,或機壓合??啥嚅_口多層壓合,在發(fā)熱盤處放置一張3.0mm厚FSF3000保溫板,或20張160克GKR160起平衡保溫作用。(鋼板厚1.6mm,型號:TMP1600)上放一張FWT50絕緣板層壓離型膜,離型膜上面放環(huán)氧樹脂絕緣板產(chǎn)品,再在產(chǎn)品上面放一張FWT50絕緣板層壓離型膜,離型膜上面放上1.6mm厚TMP1600壓合鋼板,這樣就是一個組合,建議一個開口可以放10到15個組合,大部份壓機有個6個開口。壓合1個小時,溫度設置為175度,壓力60公斤左右。
絕緣板層壓熱電行業(yè)常用寬度有250mm,260mm,265mm,270mm,280mm,300mm,330mm,350mm,480mm,520mm,540mm,550mm,560mm,580mm,630mm,650mm,680mm,720mm,750mm,770mm,790mm,,820mm,850mm,860mm,870mm,890mm,920mm,930mm,970mm,1000mm,1020mm,1030mm,1050mm,1220mm,1250mm,1260mm,1270mm,1290mm,1300mm,1322mm,1500mm,1560mm。
