Iyini I-PU Foam Enwebekayo Futhi Isetshenziswa Kanjani?

I-PU Foam enwebekayo, eyaziwa nangokuthi i-polyurethane foam, iyinto eguquguqukayo enezinhlobonhlobo zezinhlelo zokusebenza kuzo zonke izimboni ezahlukahlukene. Leli gwebu lihlukile ngenxa yekhono lalo lokunwebeka kakhulu lapho livezwa emoyeni, okwenza kube yisinqumo esihle kakhulu sokugcwalisa izikhala, izikhala zokuvikela i-insulating, nokudala imikhiqizo ehlukahlukene.

Ukwakheka Kwe-PU Foam Enwebekayo

Igwebu le-PU elinwebekayo lakhiwa izingxenye ezimbili eziyinhloko: i-polyol ne-isocyanate. Lezi zingxenye ezimbili zixutshwe ndawonye ngesilinganiso esithile ukuze zenze ukusabela kwamakhemikhali, okuholela ekudalweni kwegwebu. I-Polyol wuhlobo lotshwala olusetshenziswa njengesisekelo se-foam, kuyilapho i-isocyanate iyinhlanganisela ye-organic esiza ukuqinisa igwebu uma isinwetshiwe.

Igwebu laziwa nangokwakheka kwamaseli avaliwe, okwenza inethiwekhi eqinile yamaseli agcwele igesi. Lesi sakhiwo yiso esinikeza igwebu izakhiwo zalo ezingasindi futhi zokuvikela, okulenza libe yinketho ekahle ezinhlobonhlobo zezinhlelo zokusebenza.

Inqubo Yokwandisa ye-PU Foam

Uma i-PU Foam enwebekayo ivezwa emoyeni, iba nenqubo ebizwa ngokuthi ukunwetshwa. Phakathi nale nqubo, igwebu landa ngokushesha futhi ligcwalise isikhala elibekwe kuso. Ukwandiswa kubangelwa ukusabela phakathi kwezingxenye ze-polyol ne-isocyanate, ezikhulula i-carbon dioxide gas njengomkhiqizo. Le gesi igcwalisa amangqamuzana egwebu, ibangele ukuba ande futhi iqine.

Izinga lokunwetshwa lingalawulwa ngokulungisa isilinganiso se-polyol ne-isocyanate, kanye nezinga lokushisa kanye nomswakama wendawo. Lokhu kwenza igwebu le-PU elinwebekayo libe yinto eguquguqukayo engenziwa ngezifiso ukuhlangabezana nezidingo ezithile zezinhlelo zokusebenza ezahlukene.

Izicelo ze-PU Foam Enwebekayo

Igwebu le-PU elinwebekayo linohlu olubanzi lwezinhlelo zokusebenza kuzo zonke izimboni ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile. Enye yezinto ezivame ukusetshenziswa kakhulu zaleli gwebu embonini yezokwakha, lapho lisetshenziselwa ukufakwa, ukugcwalisa izikhala, nokudala izakhiwo ezingasindi. Izakhiwo zokuvikela igwebu zisiza ukulawula izinga lokushisa nokunciphisa izindleko zamandla, okulenza libe yinketho ekahle yezakhiwo zokuhlala nezohwebo.

Ngokungeziwe embonini yezokwakha, igwebu le-PU elinwebekayo libuye lisetshenziswe embonini yezimoto ukudambisa umsindo, ukulawula ukudlidliza, kanye nokumuncwa komthelela. Ikhono legwebu lokunwebeka futhi livumelane nezimo ezihlukene lenza kube ukukhetha okuhle kakhulu ekudaleni izixazululo ngokwezifiso zezimoto.

Izinzuzo Ze-PU Foam Enwebekayo

Kunezinzuzo ezimbalwa zokusebenzisa igwebu le-PU elinwebekayo ezinhlelweni ezahlukahlukene. Enye yezinzuzo eziyinhloko zaleli gwebu uhlobo lwalo olungasindi, okwenza kube lula ukuliphatha nokuthutha. Ikhono legwebu lokukhulisa nokugcwalisa izikhala lisiza futhi ekudaleni isivalo esiqinile, kwehlise ukuvuza komoya kanye nokwenza ngcono ukusebenza kahle kwamandla.

Igwebu le-PU elinwebekayo liyaziwa nangezakhiwo zayo ezinhle kakhulu zokuvikela, ezisiza ukulawula izinga lokushisa nokunciphisa izindleko zamandla. Isakhiwo samaseli avaliwe wegwebu sidala umgoqo ovimbela ukudluliswa kokushisa noma ukubanda, okulenza libe yinketho ekahle kukho kokubili izinhlelo zokusebenza zasendlini nezangaphandle.

Isiphetho

Igwebu le-PU elinwebekayo liyinto eguquguqukayo enezinhlobonhlobo zezinhlelo zokusebenza kuzo zonke izimboni ezahlukahlukene. Izakhiwo zayo eziyingqayizivele, njengemvelo engasindi, izakhiwo zokuvikela, kanye nekhono lokunwebeka, kuyenza ibe yisinqumo esihle kakhulu sokugcwalisa izikhala, izindawo zokufaka i-insulating, nokudala izixazululo ezenziwe ngokwezifiso. Kungakhathaliseki ukuthi kusembonini yezokwakha ukuze kufakwe inhlabathi noma embonini yezimoto yokudambisa umsindo, igwebu le-PU elinwebekayo lifakazele ukuthi liyinto ebalulekile engahlangabezana nezidingo ezithile zezinhlelo zokusebenza ezahlukene.
