Kupaka kwa madzi a polyurethane ndi mtundu wa prepolymer yomwe ili ndi Isocyanate yomwe imakonzedwa ndikuwonjezera ma polymerization a Isocyanate, polyether ndi zina zotero, ndi chothandizira, chowonjezera cha anhydrous, anhydrous kudzaza wothandizila, zosungunulira, ndi zina zotero. njira.Kupaka kotereku ndikokutira-kuchiritsa (kuchiritsa chinyezi) ndi mphamvu yayikulu, kutalika kwakukulu, kukana madzi abwino ndi zina zotero.Wamphamvu kusinthika kwa mapindikidwe a udzu mizu.Chophimba chopanda madzi cha polyurethane ndi mtundu wa chinthu chimodzi choteteza chilengedwe chopanda madzi chomwe chimagwiritsidwa ntchito mumadzimadzi.Zimakhazikitsidwa ndi polyurethane prepolymer yotumizidwa kunja popanda phula ndi phula.Ndi chinyezi mumlengalenga pambuyo kukhudzana kuchiritsa, pamwamba pa maziko kupanga wosanjikiza wa amphamvu ndi amphamvu msokonezo odana ndi filimu.
Zogulitsa
(1) itha kugwiritsidwa ntchito mwachindunji pamadzi osiyanasiyana onyowa kapena owuma.
(2) ndi zomatira amphamvu pamwamba m'munsi, filimu mu polima zakuthupi akhoza kulowa m'munsi padziko yaying'ono ming'alu, amphamvu kutsatira.
(3) filimuyo imakhala yosinthika bwino, yosinthika bwino pakukulitsa kapena kusweka, komanso kulimba kwamphamvu kwambiri.
(4) kutetezedwa kwa chilengedwe, malo osavulaza, osawononga, osavulaza munthu.
(5) kukana bwino kwa nyengo, kutentha kwakukulu sikumatuluka, kutentha kochepa sikumang'amba, ntchito yabwino yotsutsa ukalamba, kukana mafuta, kukana kuvala, kukana ozoni, asidi ndi kukokoloka kwa alkali.
(6) filimu ❖ kuyanika ndi yaying'ono, wosanjikiza madzi ndi wathunthu, palibe mng'alu, palibe Pinhole, palibe kuwira, ndi nthunzi permeability madzi Coefficient ndi yaing'ono.(7) yomanga ndi yosavuta, nthawi yomanga ndi yochepa, yokonza ndi yabwino (8) malinga ndi kufunikira, angagwiritse ntchito mtundu uliwonse (9) khalidwe ndi lopepuka, sizikuwonjezera katundu womanga..
