Ama-polyurethanes atholakala cishe yonke indawo empilweni yanamuhla;isihlalo ohlezi kuso, umbhede olala kuwo, indlu ohlala kuyo, imoto oyishayelayo - konke lokhu, kanye nezinye izinto ezingenakubalwa ozisebenzisayo ziqukethe ama-polyurethanes.Lesi sigaba sihlola ezinye zezicelo ezivame kakhulu ze-polyurethanes futhi sinikeza ukuqonda ngokusetshenziswa kwazo.

Itholakala kuphi?

Izembatho

Izingubo zokugqoka zesimanje eziningi, kungakhathaliseki ukuthi ezezimoto namakhebula, phansi nezindonga, noma amabhuloho nemigwaqo, aqukethe ama-polyurethanes, avikela ngokuphepha nangempumelelo izindawo eziveziwe ezakhiweni nasezinhlotsheni ezihlukahlukene zokungcola, ukuze zibukeke zingcono futhi zihlale isikhathi eside.

Ukuqina, ukumelana nokugqwala kanye nokumelana nesimo sezulu kwama-polyurethanes kuwenza afanelekele ukumbozwa zonke izinhlobo zezindawo.Izicelo zisukela ekwakhiweni kukakhonkolo njengamabhuloho nezakhiwo zemizila yezimoto, kuya kumakalishi ensimbi kaloliwe kanye nefenisha yokhuni.

Ama-Adhesives / ama-binders

Ama-polyurethanes ahlukahlukene kangangokuthi ayatholakala futhi ngendlela yeglue engahlanganisa ngokuphepha izinto ezihlukene, njengokhuni, irabha, amakhadibhodi noma ingilazi.

Amaphrojekthi wokwakha, ikakhulukazi, asebenzisa ama-polyurethane glues.Abakhiqizi bokupakisha nabakhiqizi befenisha yangaphandle, bobabili abadinga ukuqina namandla emikhiqizweni yabo, futhi bavame ukuthembela ezintweni ezinamathelayo ze-polyurethane.

Ama-polyurethanes awusizo ekukhiqizeni izinhlelo zokusebenza ezintsha ezenziwe ngezinto ezilahliwe nezigaywe kabusha.Isibonelo, amathayi ezimoto angasetshenziswa ekugcineni angenziwa abe izinkundla zokudlala zezingane, amathrekhi ezemidlalo noma izindawo ezingaphezulu zezinkundla zemidlalo ngenxa yezimpawu zokunamathela ze-polyurethane.

Izimfanelo ezibophezelayo ze-polyurethane zivule amathuba amasha okuhlanganisa izinhlobo ezahlukene zezinto.Izicelo zihlanganisa amabhodi ekhwalithi ephezulu okwenza amakhabethe, izindawo zokusebenza kanye nephansi ekhishini.Ngokufanayo, ama-polyurethanes angasetshenziswa ukuhlanganisa ndawonye imvuthuluka yegwebu ukukhiqiza ukhaphethi ongaphansi.Enjaloukugaywa kabusha kwentuthukoukusiza ukugcina imithombo yemvelo yoMhlaba.Imboni yensimbi isebenzisaama-disocyanatesnjengesisekelo sokuhlanganisa ukwenza isikhunta sokubunjwa.

Izinto zokunamathisela ze-polyurethane nazo ziyasetshenziswa ekwenzeni imikhiqizo yokhuni eyinhlanganisela esebenza kahle kakhulu.Imikhiqizo yokhuni eyinhlanganisela eyenziwe ngezinsiza zamahlathi esimeme ingenye indlela yangempela yemikhiqizo yamaphaneli ekhiqizwa ezihlahleni ezinkulu ezivuthiwe ezithathe iminyaka ukukhula.Lo mkhuba uqinisekisa ukuthi kutshalwa izihlahla eziningi kunokuvunwa futhi, ngokusebenzisa izihlahla ezincane ezikhula ngokushesha ezimunca isikhutha esiningi kunezihlahla ezivuthiwe, kusiza ekunciphiseni ukugawulwa kwamahlathi.
