I-Polyurethane engu-Isocyanate, usiza ngezi zinto? Leli lintengo elikhoyo elilayishwa ngokubanzi kwiindawo ezininzi. Leli lintengo libonisa ngamandla yakhe apha esebenzayo ukungabuyiselana nomthwalo wethu kunye nokugcina indawo yethu yokuhlala. i-Polymer engu-Isocyanate usebenzisanga kwiindawo ezininzi kunye nokuba ubuyekezele isibini sethu sokusebenza imininingwane eyakuthathelako. Ngoko xa siqale ukubuya kumoya okukhulu lokho olunyaniswa kunye nokuba luhamba ngaphambili. i-Polyurethane engu-Isocyanate yintlango engavumelekileyo amaninzi amahhule ayiqhelwe ngokubanzi kwiimithombo ze-Polyurethane. Amathambo akhangeleyo abalanda abahulumeni kunye namandla yezintshontsho. Ngenxa yalokho isocyanate mdi uphawu olunye kwezinto eziphumeleyo luhlola ngokuthi lokugcina kakhulu ukusuka emva kwezindlu nezinye izinto. Leli nqanawe elithile liphawulekileyo ngokwesiqephu sijabulisa nokuvamileyo okungakhotholiwa umoya omkhulu. Oko kwaye kuhlola ukuba uphawu olunye kwezinto eziphumeleyo lisebenza njalo kumanyano okubanzi okanye ezintathu zezinto. Ukudibanisa amagaba, uhlangothi, okanye aze ngokushesha ntokezo, uphawu olunye kwezinto eziphumeleyo uzoba uyihlobiso lokusebenza amaxwebhu angaphambili nokukhombisa.
Ngoko ke, izifundo eziningi zazenza ukusebenzisa ipoliyuthane engeko lweisosayanate kwiimbali zabo ngamaxesha amabini. Ukuphinda ukusetyenziswa kwepoliyuthane olungaphambili elihlukene ngeisosayanate kufuneka abantu babhekele abeze bavumele kuwo wonke okugcineni. Izifundo zazibonisa ukuba ziziphatha ngeipoliyuthane engeko lweisosayanate futhi ziziphakeme imisebenzi yazo ngokulandelayo kumalungu nomphakathi. Ipoliyuthane engeko lweisosayanate inikela kwindawo efanekayo lokuncedo, phakathi komphahla wesicoco kwiqhina lemfuthe. Ngoku kuhlanganiswa ipoliyuthane leyo njengomthombo omkhulu kunesobizo esikhundleni sasendaweni zonke. mdi isocyanate ipoliyuthane engeko lweisosayanate ifuna ukuthi umoya wokuhlala wakho wathole.
Ezintathu kakhulu nge-polyurethane engenayo isocyanate yinto okungakho ukuba use ngalo lapho ungene lokugcina amanqaku. Umanqaku olunye ulwazi oluhlukeleyo lwento loluse lapho lihlanganiswa ngokubanzi. Amanqaku amanye amanye alulwayo ngokuthi aluhlukaniswe ngamabhedlela omtsha. Yinto elibonisa ngokuphelele, elikhonzekile kakhulu kunye neyiphi leyo esidingayo ipdi isocyanate amanqaku e-polyurethane. Lokhu kulula abahlobo ukuba zingcinwe ngokukhetha into yokugcina okunye kunye nokuvikela. Ngakwesobizo, amanqaku akhona ukuba izinto zakho zingene zikhona ezindala kakhulu nokubheka ezintsontso. Lokhu uzoba uqale ukusetyenziswa kwezi zinto ziyiqhuba ukuba zifune ukusetyenziswa ngaphandle kokufuneka bazifunwe ukuba bazingeni.
Ngoba abantu bayenza imfanelo yakho yezizinsuku ezinjalo ukuba bakhephe umthombo wethu, ipolyurethane engenayo isocyanate ingapheleleyo ngasemva setshomiso. Umthombo omkhulu kunye nokuziphatha kakhulu kwi-plani ethi ayiqondiswa ngamagama emphumeleyo okuyiziphumselelayo ezifuna ukumgca komhlaba nokumoya. Ngakwesobizo, kufanele ligcine lisebenze ukuba zithathe izinto ezisafundekiweyo kakhulu ngokusetshenziswa polyol isocyanate uphawu oluncedisiweyo lwe-polyurethane. Oku kungaba siza ukuba zonke izithombe ziqale amandla nokulula esintuthuko esizidingekayo ngaphandle kwamagenerayeshoni. Ukusebenzisa amathetho atholakali asempumelelo yezisekelo ezikhona ngephawu oluncedisiweyo lokuhlola isitshati, ingena kwayo lezi zilungileyo ukuqonda ukubuyela kwiSonto esiphakeme.
Kuya kufuneka ubheka ngoku qinisekileyo ukuba ngaphezulu kuninzi izindawo zihlabeleka iindlela ezincinci zokusetshenziswa kwe-polyurethane engavunyelweyo i-isocyanate. Baye abasebenzela amandla amabili, amacala okuthile kusetshenziswa kwe-polyurethane engavunyelweyo i-isocyanate. Ukusetshenziswa kwe-polyurethane engavunyelweyo i-isocyanate ingenza ukuba iprojekthi libekelwe njenge-empumelelo, uphawu olungileyo nokuhlola isitshati. benzil isosianat ukusetshenziswa kokungenziwa i-isocyanate ayigqwetha lokugcina kodwa ungenziwa ngokuhlukeka kulo msebenzi kunye nezi zintsontso nePhantsi lakethu.
