Umsesane wokutywina we-polyurethane ubonakaliswa ngokumelana nokunxiba, i-oyile, i-asidi kunye ne-alkali, i-ozone, ukuguga, ubushushu obuphantsi, ukukrazula, impembelelo, njl njl.Ukongeza, umsesane wokutywina awunyangeki nge-oyile, i-hydrolysis ayinyangeki, ayinyangeki, kwaye inamandla aphezulu, ilungele izixhobo zeoyile ephezulu, izixhobo zokuphakamisa, izixhobo zoomatshini bokubumba, izixhobo ezinkulu ze-hydraulic, njl.
Umsesane wokutywina we-polyurethane: I-polyurethane ineempawu ezintle kakhulu zoomatshini, kwaye ukumelana kwayo nokunxiba kunye nokumelana noxinzelelo oluphezulu kuphezulu kakhulu kunezinye iirubha.Ukumelana nokwaluphala, ukuxhathisa kwe-ozone kunye nokuxhathisa i-oyile kukwalungile, kodwa kulula ukwenza i-hydrolyze kubushushu obuphezulu.Ngokuqhelekileyo isetyenziselwa ukunyanzeliswa koxinzelelo oluphezulu kunye nokunxitywa kwekhonkco lokutywina, njengeesilinda ze-hydraulic.Ngokubanzi, uluhlu lobushushu ngu-45~90 ℃.
Ukongeza ekufezekiseni iimfuno jikelele zokutywinwa kwezixhobo zokutywina, amakhonkco okutywina e-polyurethane nawo aya kuhoya le miqathango ilandelayo:
(1) Igcwele ukunwebeka nokomelela;
(2) Amandla afanelekileyo omatshini, kubandakanywa amandla okwandisa, ukunyusa kunye nokuchasana nokukrazula.
(3) Ukusebenza okuzinzileyo, kunzima ukudumba phakathi, kunye nefuthe elincinci le-thermal shrinkage (i-Joule effect).
(4) Kulula ukusetyenzwa nokubunjwa, kwaye inokugcina ubungakanani obuchanekileyo.
(5) Ayiwudli umphezulu wonxibelelwano kwaye ingcolise indawo ephakathi.
