Asbestos shingle
Mataira eresin ekugadzira akapfupikisa zvakanakira mataira echinyakare, uye akavandudza zvikanganiso zviripo. Muumbirwo wayo mukuru iPVC resin, pamusoro payo iASA engineering resin ine resistance yakanyanya-kupisa, pakati pane skeleton layer, iyo inogona kuwedzera kusimba uye resistance ye resin tile, pasi pane PVC itsva inodzivirira kupfeka, kushandiswa kwezvikamu zvitatu zve co-extrusion tekinoroji yakambogadzirwa, ine resistance yakanyanya yekudzivirira ngura, resistance uye resistance.
Tile yeresin yakagadzirwa
Tile yeASA resin yakagadzirwa nepamusoro peASA resin munzvimbo yechisikigo ine simba guru remamiriro ekunze, inogona kuita kuti tile yeASA resin igare kwenguva refu ichiratidzwa nechiedza cheultraviolet, hunyoro, kupisa, kutonhora, mamiriro akaoma, inogona kuchengetedza kugadzikana kwemavara uye mashandiro emuviri, zvichiratidza nekuyedza, tile yeASA resin yakagadzirwa ne60% inotevera mhando dzese dzeasidhi, alkali uye munyu dzinonyoroveswa kwemaawa makumi maviri nemana pasina maitiro emakemikari, mushure memushumo wekuyera kukwegura kwekugadzira (kukwegura kwekugadzira kwemaawa 8000, zvakaenzana nekushandiswa chaiko kwemakore anopfuura makumi matatu), inoshandiswa zvakanyanya mukuvaka kwemisha mitsva yekumaruwa, dzimba, dzimba dzekutengesa, maindasitiri, zvekurima uye zvivakwa zveveruzhinji munzvimbo dzakadai sedenga sekushandiswa kwekushongedzwa kwemvura, kwakakodzera kwazvo nzvimbo dzegungwa dzemunyu. Kudzivirira ngura kwakasimba, uye denga remhepo rakakomba rinoshandiswa.
