Isihlungi sekhandlela somugqa wefilimu we-BOPP

Ekukhiqizeni ifilimu ye-BOPP, ukuncibilika kwe-polypropylene ephezulu yamangqamuzana kuqala kwenziwa ishidi noma ifilimu ewugqinsi ngekhanda lomshini omude nelincane, bese kuba semshinini okhethekile wokwelula, ezingeni lokushisa elithile kanye nesivinini esimisiwe, kanyekanye noma isinyathelo. ngesinyathelo Ifilimu yeluliwe ngezindlela ezimbili eziqondile (i-longitudinal ne-transverse), futhi ngemva kokupholisa okufanele noma ukwelashwa kokushisa noma ukucubungula okukhethekile (njenge-corona, i-coating, njll.).

Amafilimu e-BOPP asetshenziswa kakhulu ahlanganisa: ifilimu ye-polypropylene ejwayelekile ye-biaxially oriented, ifilimu ye-polypropylene evalwe ngokushisa, ifilimu yokupakisha kagwayi, ifilimu ye-polypropylene pearlescent ye-biaxially, ifilimu eyenziwe nge-polypropylene eyenziwe nge-biaxially, ifilimu yokuhlanganisa, njll.

Ifilimu ye-BOPP iyinto ebaluleke kakhulu yokupakisha eguquguqukayo. Ifilimu ye-BOPP ayinambala, ayinaphunga, ayinaphunga, ayinabo ubuthi, futhi inamandla aqinile aqinile, amandla omthelela, ukuqina, ukuqina kanye nokungafihli lutho okuhle.

Amandla angaphezulu efilimu ye-BOPP aphansi, futhi ukwelashwa kwe-corona kuyadingeka ngaphambi kokunamathisela noma ukuphrinta. Ngemuva kokwelashwa kwe-corona, ifilimu ye-BOPP inokuvumelana nezimo ezinhle zokuphrinta futhi ingaphrintwa ngokweqile ukuze ithole ukubukeka okuhle, ngakho-ke ivame ukusetshenziswa njengendawo yongqimba yangaphezulu yefilimu eyinhlanganisela.

Isikrini sokuhlunga siyingxenye ebaluleke kakhulu ye-extruder, futhi imikhiqizo efanelekayo kuphela engakhiqizwa ngesikrini sokuhlunga. Isikrini sesihlungi se-extruder sisetshenziselwa ukuhlunga nokuhlanganisa izinto ezihlukahlukene ze-viscous nemikhiqizo efana nepulasitiki, imicu yamakhemikhali, irabha, izinto zokunamathisela ezincibilikayo ezishisayo, izinto zokunamathisela, izinto zokumboza, nezingxube. Isikrini sesihlungi se-extruder sinohlobo lwe-mesh. Ngohlobo lwebhande le-mesh, i-extruder ingashintsha isikrini sokuhlunga ngaphandle kokuphazamisa ukukhiqizwa ngokusebenzisa isishintshi sesikrini esizenzakalelayo, ukonga umsebenzi nesikhathi, ukusebenza komkhiqizo kuzinzile, kuqaphela ukuguqulwa kwesikrini okuzenzakalelayo nokusebenza kwamahhala, ukwandisa isikhathi sokuhlunga esisebenzayo, nokunciphisa izindleko zokukhiqiza. .
