Cov khoom siv khau pu yog tsim los ntawm cov khoom siv hluavtaws hluavtaws tawv tawv, nws cov kev ntxhib los mos muaj zog thiab ruaj khov, xws li PVC tawv, Italian ntawv, tawv tawv, thiab lwm yam., cov txheej txheem tsim khoom yog me ntsis nyuaj. Vim tias PU puag daim ntaub muaj lub zog tensile zoo, nws tuaj yeem pleev xim rau hauv qab, los ntawm sab nraud tsis tuaj yeem pom qhov muaj nyob ntawm daim ntaub hauv paus, tseem hu ua tawv tawv, yog yam ntxwv ntawm lub teeb yuag, hnav tsis kam, tiv thaiv plam, txias. thiab tshuaj tiv thaiv corrosion, tab sis yooj yim los tsim kua muag, tsis zoo txhua yam muaj zog thiab tsim kua muag kuj, lub ntsiab xim yog dub los yog xim av, mos zoo nkauj.
PU tawv khau yog khau ua los ntawm cov ntaub sab sauv ua los ntawm cov tawv nqaij ntawm cov khoom siv polyurethane. Qhov zoo ntawm PU tawv khau kuj zoo lossis phem, thiab cov khau tawv PU zoo tseem kim dua li cov khau tawv tiag.
Cov txheej txheem tu: Ntxuav nrog dej thiab tshuaj ntxuav tes, tsis txhob siv roj av txhuam, tsis tuaj yeem ntxuav kom qhuav, tsuas yog ntxuav, thiab ntxuav qhov kub tsis tshaj 40 degrees, tsis tuaj yeem raug tshav ntuj, tsis tuaj yeem tiv taus qee cov kuab tshuaj organic.
Qhov sib txawv ntawm PU tawv khau thiab khau tawv tawv: qhov zoo ntawm cov khau tawv tawv yog tias tus nqi pheej yig, qhov tsis zoo yog qhov yooj yim rau tawv, thiab tus nqi ntawm PU hluavtaws tawv khau yog siab dua li ntawm PVC tawv tawv khau. Los ntawm cov qauv tshuaj, cov ntaub ntawm PU hluavtaws tawv khau yog ze rau cov tawv nqaij tawv tawv khau nws tsis siv cov yas kom ua tiav cov khoom muag, yog li nws yuav tsis ua tawv, nkig, thiab muaj qhov zoo ntawm cov xim nplua nuj, ntau yam. ntawm cov qauv, thiab tus nqi yog pheej yig dua li tawv npuag khau, yog li nws tau hlub los ntawm cov neeg siv khoom
