Inkqubo yogwebu
1. Indlela ye-Prepolymer
Inkqubo ye-pre-polymer indlela yokwenza amagwebu kukwenza (izinto ezimhlophe) kunye (izinto ezimnyama) zibe yi-polymer yangaphambili, kwaye emva koko wongeze amanzi, i-catalyst, i-surfactant, ezinye izongezo kwi-pre-polymer, kwaye udibanise phantsi kwesantya esiphezulu sokuvuselela. I-Soak, emva kokunyanga, inokunyangwa kwiqondo lokushisa elithile
2. Indlela ye-semi-prepolymer
Inkqubo ye-foaming yendlela ye-semi-prepolymer kukwenza inxalenye ye-polyether polyol (izinto ezimhlophe) kunye ne-disocyanate (izinto ezimnyama) kwi-prepolymer, kwaye emva koko udibanise enye inxalenye ye-polyether okanye i-polyester polyol kunye ne-diisocyanate, amanzi , I-Catalysts, i-surfactants, ezinye izongezo, njl., zongezwa kwaye zixutywe phantsi kwesantya esiphezulu sokuvuselela ugwebu.
3. Inkqubo yogwebu enenyathelo elinye
Yongeza i-polyether okanye i-polyester i-polyester (izinto ezimhlophe) kunye ne-polyisocyanate (izinto ezimnyama), amanzi, i-catalyst, i-surfactant, i-agent evuthelayo, ezinye izongezo kunye nezinye izinto eziluhlaza kwisinyathelo esinye, kwaye udibanise phantsi kwesantya esiphezulu kunye ne-foam.
Inkqubo yenyathelo elinye logwebu yinkqubo esetyenziswa ngokuqhelekileyo. Kukwakho nendlela yokwenza amagwebu, eyona ndlela ilula. Emva kokuba zonke izinto eziluhlaza zilinganiswe ngokuchanekileyo, zifakwe kwisitya, kwaye ke ezi zinto zixutywe ngokulinganayo kwaye zifakwe kwi-mold okanye indawo efuna ukugcwaliswa nge-foam. Qaphela: Xa ulinganisa, i-polyisocyanate (izinto ezimnyama) kufuneka zilinganiswe ekugqibeleni.
I-polyurethane foam eqinile idla ngokuba namagwebu kubushushu begumbi, kwaye inkqubo yokubumba ilula. Ngokwenqanaba lobuchwephesha bokwakha, lunokwahlulwa lube ngamagwebu ogwebu olwenziwa ngesandla kunye nogwebu lomatshini. Ngokoxinzelelo ngexesha le-foaming, inokwahlulwa ibe yi-high-pressure foaming kunye ne-low-pressure foaming. Ngokwendlela yokubumba, inokwahlulwa ibe ukugalela amagwebu kunye nokutshiza ugwebu.
Umgaqo-nkqubo
Iarhente yogwebu lwePolyurethane yadweliswa nguMphathiswa wezoKwakha njengemveliso eza kukhuthazwa kwaye isetyenziswe ngexesha "leSicwangciso seMinyaka emiHlanu".
Ulindelo lwemarike
Ukususela kwiimveliso ze-2000 zakhuthazwa kwaye zasetyenziswa e-China, imfuno yemarike iye yanda ngokukhawuleza. Ngo-2009, ukusetyenziswa ngonyaka kwimarike yesizwe yokwakha kudlule kwi-80 yezigidi zeetoti.
