Ukuqhathanisa i-Polyethylene Foam kanye ne-Polyurethane Foam: Umehluko Oyinhloko

Uyini Umehluko Phakathi Kwe-Polyurethane ne-Polyethylene Foam?

Nakuba amagama abo ezwakala ngokufanayo, i-polyurethane ne-polyethylene foam zihluke kakhulu ekubunjweni nasekusebenzeni. Bobabili bangamalungu omndeni obanzi wezinto ze-foam, kodwa bafeza izinhloso ezihlukene. Ukuqonda lo mehluko kubalulekile lapho ukhetha igwebu elilungile—ukuthi uklama ingxenye yomkhiqizo noma ukhetha amaphakheji okuvikela.

Lezi yizici eziyisisekelo zezinhlobo ezimbili zegwebu ezisetshenziswa kakhulu.

Iyini i-Polyurethane Foam?

Igwebu le-polyurethane liyinto ethambile, enesisindo esincane ehlukaniswa njengegwebu lamaseli avulekile . Isakhiwo samangqamuzana aso asixhumene, sivumela umoya ukuba udlule ngokukhululeka. Lokhu kunikeza igwebu umuzwa ovumelana nezimo, ocindezelayo lapho kufakwa ingcindezi. Yaziwa ngokumunca okuhle kakhulu kokushaqeka kanye nokumelana nelangabi (ehlangabezana nezindinganiso zokuphepha ze-UL 94), igwebu le-polyurethane kulula ukulisika nokulolongwa, okulenza libe nezinto ezihlukahlukene kakhulu ezisetshenziswa ezihlukahlukene.

I-polyurethane foam ngokuvamile ihlukaniswa ngezinhlobo ezimbili ezinkulu:

I-1.Ester-based polyurethane inesakhiwo seseli esicolekile, esinikeza umuzwa oqinile, oweseka ngokwengeziwe kanye nokuqina okukhulu. Nakuba inikeza ukumuncwa okuphakeme kokushaqeka, isengozini enkulu yokulimala komswakama kanye namanzi.

I-2.Ether-based polyurethane inesakhiwo esikhulu samaseli, okuvumela ukugeleza komoya okukhulu nokumelana nomswakama. Inikeza umuzwa othambile, ovumelana nezimo uma kuqhathaniswa ne-ester-based polyurethane.

I-polyurethane isetshenziswa kakhulu ekushiseni kanye nezinye izinhlelo zokusebenza eziningi.

Iyini i-Polyethylene Foam?

Igwebu le-polyethylene liwugqinsi, amaseli avaliwe aziwa ngokuqina kwawo kanye nokumelana kahle ne-hydrolysis—ngeke lonakale lapho lichayeka emanzini noma kumswakama. Lokhu kuqina kuvela ekwakhekeni kwamaseli avaliwe, avimbela ukudlula komoya noketshezi.

Amagwebu e-polyethylene ahlanganisiwe futhi anwetshiwe alungele ukufakwa kwe-thermal kanye nokudambisa umsindo. Lawa magwebu angenziwa futhi aminated ukuze kuthuthukiswe ukuvikeleka ekushiseni, kumagesi, nakwezinye izinto ezinokhahlo.

Okunye okuhlukile, igwebu le-polyethylene lobuhlalu, liyimpahla eqinile kodwa enesisindo esincane ehlala iguquguquka futhi kulula ukuyenza. Ayinuki, ayinaphunga, futhi iyisivikelo esisebenza kahle kakhulu, siyenza isebenziseke kakhulu ezinhlelweni zasolwandle kukho kokubili usekelo nokunethezeka.

Ukusebenzisa i-Polyurethane ne-Polyethylene Foams Ndawonye

Kwezinye izinhlelo zokusebenza, kokubili amagwebu e-polyurethane ne-polyethylene asetshenziswa ndawonye ukuze kwandiswe ukusebenza. Isibonelo esivamile sisemikhiqizweni yokugoba, lapho inkaba yegwebu le-polyurethane ethambile igqitshwa ngaphansi kwe-polyethylene foam top eqinile. Le nhlanganisela idala indawo eqinile enentofontofo engaphansi kanye nokumunca ukushaqeka, iyenze ifaneleke ukuhlala, omata bokusubatha, nokusetshenziswa okufanayo.

Udinga usizo lokukhetha i-polyurethane efanele noma i-polyethylene foam yephrojekthi yakho? Ochwepheshe bethu bokwenza amagwebu kwa-TOPSUN bakhona ukuze basize. Xhumana nathi namuhla!
