Iluphi uhlobo lwefilimu enamathelayo encibilikayo enamandla amakhulu okubopha?
Izinamatheliso ezincibilikayo ezishisayo zibonwa njengezinamatheliso ezinobungani bemvelo. Yiqiniso, imikhiqizo yefilimu enamathelayo encibilikayo eshisayo eyenziwe ngezinamatheliso ezincibilikayo ezishisayo nayo inobungani bemvelo. Kungakho amafilimu anamathelayo ancibilika athola ukunakwa kakhulu namuhla.
Ifilimu ye-adhesive ye-hot melt ingahlukaniswa ngezinhlobo eziningi ngokusho kwempahla eluhlaza. Okuvame kakhulu ifilimu yokunamathela ye-EVA hot melt, ifilimu yokunamathisela eshisayo ye-TPU, ifilimu ye-PA hot melt adhesive, ifilimu ye-PES hot melt adhesive, nefilimu ye-PO hot melt adhesive. Izinhlobo, amagama amakhemikhali ahambisanayo yi-ethylene-vinyl acetate polymer, i-thermoplastic polyurethane, i-polyamide, i-polyester, i-polyolefin. Lezi zinhlobo zama-polymers amangqamuzana aphezulu zinezici zazo, ngakho-ke ukusebenza kwemikhiqizo yefilimu enamathelayo encibilikayo eshisayo eyenziwe nayo ihlukile, kodwa njengomkhiqizo wokunamathisela, inkomba yokusebenza ebaluleke kakhulu ingase ibe amandla okubopha. Iluphi uhlobo lomkhiqizo wefilimu enamathelayo oncibilika oshisayo onamandla amakhulu okunamathela?
Eqinisweni, ayikho indlela yokunikeza impendulo enembile embuzweni wokuthi yimaphi amandla esibopho angcono kakhulu. Ngenxa yokuthi izinhlobo ezahlukene zokunamathisela zinezici ezihlukene zokuhlanganisa zezinto ezihlukahlukene, amandla okubopha abonisiwe nawo ahlukile. Isibonelo, umphumela wokubopha wefilimu enamathelayo ye-PES eshisayo encibilika ensimbi ngokuvamile ungcono kunaleyo yefilimu enamathelayo ye-TPU eshisayo encibilika, kodwa uhlobo oluthile lwefilimu enamathelayo ye-TPU eshisayo encibilikisa ingase ibe ngcono kakhulu kunefilimu yokunamathisela eshisayo ye-PES ukuze inamathele ku-PVC. amapulasitiki. Ngakho-ke, umbuzo wokuthi iyiphi impahla enamandla okunamathisela engcono kakhulu ayiqondile kakhulu futhi kunzima ukuyiphendula. Ngokuvamile, uhlobo oluthile lomsebenzi lunganikezwa ngaphambi kokuba lunqunywe ngokusekelwe kokuhlangenwe nakho.
Kunjalo, kuvame ukuba nzima ukwahlulela ngokunembile ukuthi yiluphi uhlobo lwefilimu enamathelayo encibilikayo eshisayo engcono kakhulu ukuyibopha ngemva kokunikezwa uhlobo oluthile lwempahla. Singahlulela kuphela umphumela ojwayelekile ngokusekelwe esimweni esivame kakhulu nolwazi. Ukuqinisekisa kokugcina kusadinga ukuhlolwa kokuhlola ukufakazela ukuthi kunembe kakhulu. Ngoba noma ngabe impahla iyafana, umehluko ekuqineni kwendawo, ukungezwani kwendawo kanye nezinye izici ekugcineni kuzothinta ukuhlangana kwento ngenxa yomehluko enqubweni.
