Rinjiga Polyurethane ee biyaha
Trapezium-ka gaarka ah ee biyaha ku salaysan, sayniska kiimikaad ee qaranka, biyaha deionized, waxyaabaha lagu daro biyaha iyo buuxinta ilaalinta deegaanka iyo qaybaha kale, kuma jiraan benzene, qoys, benzene fasalka labaad iyo dareerayaasha kale ee organic. Alaabta waxaa diyaariyey by iyada oo la adeegsanayo resin polyurethane aliphatic-ku-salaysan sida filim samaynta walxaha aasaasiga ah, HDI oo ah wakiilka daawaynta, ku darida buuxinayaasha deegaanka u saaxiibka ah iyo kaaliyeyaasha shaqaynta. Filim buuxa, dhalaal sare, midab dhalaalaya. Ku dheggan wanaagsan, adkaanta sare, iska caabinta cimilada heer sare ah.
Goobta codsiga
Ku habboon shuruudaha dusha sare, shuruudaha iska caabinta cimilada sare ee dahaarka rinjiga sare. Inta badan waxaa loo isticmaalaa qurxinta dusha sare ee qaybaha birta sida foosto koronta dabaysha, qalabka farsamada, mashiinada dhismaha, tuubada saliidda petrochemical, iwm. Waxay leedahay iska caabin cimilo oo aad u fiican oo dibadda ah iyo iska caabin daxalka.
Daaweynta dusha sare
1. Dusha sare waa inay ahaato mid nadiif ah oo qallalan, iyo daaweynta dusha sare ee substrate waa inay buuxisaa shuruudaha.
2. Qalabka loo isticmaalo dhismaha waa in uu ahaado mid qalalan oo nadiif ah. 3.
3. Waa mamnuuc in lala xiriiro aashitada iyo alkali inta lagu jiro habka diyaarinta rinjiga iyo dahaadhka.
4. dhexda rinjiyeynta waa in si adag loo xakameeyaa, marka heerkulku yahay 25′C, mudada rinjiyeynta waa in aanay ka yarayn 12 saacadood.
5. Ma rinjin karo qaro weyn, filimku kama badnaan karo 40μm ama wuu xumbo.
6. Dhismaha iyo qalajinta iyo daaweynta inta lagu jiro qoyaanka qaraabada ah kama badna 75%, heerkulku ma noqon karo wax ka yar 0 ℃ C, haddii kale filimku si buuxda uma daweyn karo saameynta.
