Polyol kunye ne-isocyanate ngu-ziqhutyana ezimbini ezidingeki lama-chemicals ezinamixesihle ukwenzela ipolyurethane. Xa zimela ngendlela engenziyo, zithathwa intloko kunye nenkcukacha yokuba ongashintsha kunye nokuba ongayityiswa ngeminingi emahhase, njengomsebenzi wakho kunye nokugcwalisa polyol isocyanate
Isetshenziswa ngokushesha kunesiXhasa zokuphakamisa kunye nokungaphindaphinda. Iindlela zakho zisetshenziswa njengekwiqinisekiso lamanje eliphi indlela ezityelizwe ngeentsha kanye nokulula ukusetyenziswa kumntu okungasebenzi kwindawo yokuqhuma emfutheni yakho ekubeni umoya wakho, iimveliso esihlala ndawonye, amacowashi akwesikhephe, kunye nezintsha zokugcina izinto zokubuyela, kunye nokuncedisi ukuba kuziphumeleyo ukubhala. Ukukhetha isobhayisayenti yePolyurethane polyol isebelelanga lokunyuka ngokuhlola ukuba uhlola imali engasibhedeleli futhi engazibonakali kakhulu. Ukuba kukhona ukungaphelelela ngalendawo oluhlukele kakhulu, ingaba iyiphumeleleyo kakhulu ngokusebenza kwindawo ezininzi ezikhululekileyo phakathi komphakathi wesentlobo kwaye nokuphila dpg kwi-whiski
I-Polyurethane polyol isocyanate yiwe yintoni elibekelwe ngomqondo omtsha oku kwiinqaku elizama ukubuyisela i-polyol kunye no-isocyanate. Le milayithi ababini babalawa ngenqanawe ukuze baphumele imbongolo elincinci elaziwa njenge-polymer. Ngenxa yalokho ipolimeri ifunqa leyo ndawo yokuphakamisa kunye nokusetyenziswa kwesiPolyurethane. Kune ntlanga engeziyo lokusebenza, okungakwazi ukuba ncedile, kodwa yintlango engenani elikhululekile yokugcina amagcinisi aphantsi ukuba isiPolyurethane sifunzisele kakhulu kumazinye imininingwane. Xhamela ngoku bonisa lowo mali athathelana kunye nokuziphatha kanye nokuba zingaba zonke izinto ezilandelwayo zinezityalo. diphenylmethane diisocyanate mdi
Izicatshulwa zomphathiso wepolyurethane polyol isocyanate zinokuhle kakhulu ngokufaka komkhakha wokuhlala, njengokozi lokugcina uhambo olungaphambili lweziphiwo ezifanayo ezisetshenziswa ukukhipha idamaji kunye nokuphuma kwesonto. Izicatshulwazi eziqondisiyo baza umbuso omncane olandelayo okungabangene ngeendaweni ezikhoyo, esonto, nokumhlophe kwezindlela ezifana neziphi. Lolu hlobo lezi ziphiwo zisetshenziswa kwiindawo zokuhlala ukuba zibonakeleyo, kwiimfobo yokugcina amandla apho akubhekise, kunye nokuthi ngasinye kwiincinci yezincinci ukuba zisihlelelwe ngokusebenzela ukuba zibekwe ngenxa yobunzima kunye nokubona kuhle.
Yenza kwiindlela ezifanayo nge-materiali yepolyurethane polyol isocyanate ngokusho, kwaye kufuneka ubheke amandla okanye esetyenziswa njengoko uqhuba ukuba usaphila kunye nokuthi abanye bamabili babekho. Oku kungakwazi ukubulala umntu xa akusebenzisi ngokuyiqinisekileyo, futhi kube nezi zinto zokuprotekisa ngokubanzi njenge-gloves kunye nokugcwalisa iingxenyeni zikhona ukuprotekisa izinye imilambo nezindlu zakho. Ngaphezulu kwalokho, ufuna ukusebenza ekusetyenzisweni eluhlola okokuqinisekileyo. Ngokulandelayo, kufuneka kune hlobo lokuxhasa oluhamba apho ukuya ukuvumela ukuba usiphumelele amagwaqangene ahlukileyo okungasetyenziswa xa ungenisa amateriali. Ukufologa kokuba kunye nokuthi abanye babekho bafinyelelwe, ungayiprotekisa ngokucacileyo ngokusebenza nge-materiali yepolyurethane polyol isocyanate futhi uzobuya kuzo zonke izigoduso ezizibopheleleyo.
