Ibhalansi phakathi kwezinga lokushisa eliphansi kanye nezinga lokushisa legumbi lokunamathela okuzwelayo kwe-hot melt pressure

Izinamatheliso ezincibilika ezishisayo ezizwela ukucindezelaingabonisa izici ezinhle kakhulu zokunamathela ekamelweni lokushisa, njengamandla okuxebula, ukunamathela kokuqala, njll., kodwa ukusebenza emazingeni okushisa aphansi akulungile. Ikakhulukazi ngenxa yokuzwela kwezinamathiselo ezincibilikayo ezincibilika ngokucindezela kuzinga lokushisa elizungezile. Ngokuvamile, izinto zokunamathisela ezincibilikayo ezincibilika ezizwela ukucindezela zenzelwe izimo zegumbi lokushisa elingu-25.°C, kodwa imakethe mancane amathuba okuthi yamukele izinto ezincibilikayo ezincibilika ezizwela ukucindezela ukuze zisetshenziswe ezimweni ezithile zokushisa ezivela kubahlinzeki. Ngakho-ke, kunesidingo sokuhlinzeka ngezinzwa zengcindezi eshisayo ngebanga lokushisa elibanzi.

Indaba ebaluleke kakhulu ekuklanyweni kweukucindezela okubucayi okunamathelayo okuncibilika okushisayongebanga elibanzi lokushisa elinjalo yizinga lokushisa lokushintsha kwengilazi. Izinamatheliso ezincibilika ezishisayo ezisetshenziswa ekamelweni lokushisa ngokuvamile zinezinga lokushisa lengilazi elingu-0-10.°C. Izici zokunamathela kwezinga lokushisa eliphansi lezinto zokunamathisela ezincibilikayo ezincibilika ezicindezelayo zidinga izinga lokushisa eliphansi lokushintsha kwengilazi. Kodwa-ke, izakhiwo zokugeleza / zokumanzisa zalokhu okunamathelayo ekushiseni kwegumbi kuzoncishiswa, okusho ukuthi ukusebenza kokuncibilika okushisayo okuzwela ukucindezela kuzoncishiswa. Ngokwencazelo engenhla, ngokwethiyori, chaokunamathelayo okuncibilika okushisayo okuzwela ukucindezelaingaqinisekisa ukusebenza okuhle kakhulu kokunamathela kukho kokubili izinga lokushisa legumbi kanye nezinga lokushisa eliphansi.

Nokho, uma kuziwa emakhonweni okuklama, singaba nokulinganisela kulezi zindawo ezintathu ezilandelayo.

Okokuqala, singakhetha i-elastomer ene-cross-sectional ratio efanele ukuze senze ukwakheka kwesigaba senjoloba kube phezulu ngangokunokwenzeka;

Okwesibili ukukhetha i-elastomer enesisindo esibanzi samangqamuzana.

Okwesithathu, i-adhesive ikhethiwe ukwenza amaphuzu okushisa okushintshwa kwengilazi engu-2.
