Ubutyebi bomhlaba bunqongophele kwaye kubalulekile ukuba sithathe kuphela into esiyifunayo kwaye senze isabelo sethu ukukhusela okushiyelweyo kwizizukulwana ezizayo.Iipolyurethanes zidlala indima ebalulekileyo ekugcineni ubutyebi bendalo besijikelezi-langa sethu.Iingubo ze-polyurethane ezihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zibo.Iipolyurethanes zinceda ukugcina amandla ngokuzinzileyo.Bancedisa abakhi bezakhiwo ukuba bagqume kakuhle izakhiwo ezinciphisa ukusetyenziswa kwerhasi, i-oyile nombane, ebekuya kufuneka ukuba bekungenjalo ukuzifudumeza nokuzipholisa.Enkosi kubavelisi beemoto ze-polyurethanes banokuyila izithuthi zabo ngendlela enomtsalane ngakumbi kwaye bakhe izakhelo ezikhaphukhaphu ezonga ukusetyenziswa kwamafutha kunye nokukhutshwayo.Ngaphezu koko, amagwebu e-polyurethane asetyenziselwa ukugquma izikhenkcezisi kuthetha ukuba ukutya kugcinwa ixesha elide kwaye kukulondoloze ekungcoleni.

Kwakunye nokonga amandla kunye nokukhusela izixhobo ezixabisekileyo, ngoku kukho ukugxila okwandisiweyo ekuqinisekiseni ukuba iimveliso zepolyurethane azilahlwa nje okanye zilahlwe xa zifikelela esiphelweni sobomi bazo bendalo.

Ngenxa yokuba kukho iipolyurethanesiipolymers petrochemical-based, kubalulekile ukuba sizisebenzise kwakhona xa kunokwenzeka, ukuze izinto ezixabisekileyo zingalahleki.Kukho iindlela ezahlukeneyo zokuphinda zisetyenziswe, kubandakanywa ukurisayikilishwa koomatshini kunye neekhemikhali.

Ngokuxhomekeke kuhlobo lwe-polyurethane, iindlela ezahlukeneyo zokuphinda zisetyenziswe zinokusetyenziswa, ezifana nokusila kunye nokuphinda kusetyenziswe okanye ukudibanisa amasuntswana.I-polyurethane foam, umzekelo, iguqulwa rhoqo ibe yikhaphethi yangaphantsi.

Ukuba ayiphinda isetyenziswe, ukhetho olukhethiweyo kukubuyisela amandla.Itoni yetoni, i-polyurethane iqulethe umlinganiselo wamandla afana namalahle, nto leyo eyenza ukuba ibe sisixhobo sokutya esisebenza kakuhle kwizitshisi zikamasipala ezisebenzisa amandla aveliswa ukufudumeza izakhiwo zoluntu.

Olona khetho luncinci lufunwayo kukulahla inkunkuma, ekufuneka kuphetshwe naphi na apho kunokwenzeka.Ngethamsanqa, olu khetho lusehla njengoko oorhulumente behlabathi besiya beqonda ngakumbi ngexabiso lenkunkuma ekusetyenzisweni ngokutsha kunye nokubuyisela amandla, nanjengoko amazwe egqiba umthamo wawo wokulahla inkunkuma.

Ishishini le-polyurethane nalo liqhubeka livelisa izinto ezintsha ukuvelisa imathiriyeli ezinzileyo.
