Amanye amafilimu ajwayelekile angavala ama-substrate amaningana, kodwa kumele ahlolwe ngokwehlukana kuwo wonke amazinga ethreyi. Ama-flange abheke ku-PET-, PE- kanye ne-PP ngokuvamile adinga i-chemistry ehlukile yokuvala.

Kungavinjelwa kanjani ukuvuza kwethreyi?

Sebenzisa inhlanganisela yethreyi nefilimu ehambisanayo, gcina i-flange ihlanzekile futhi ithambile, gcina izilungiselelo zokushisa nesikhathi sokucindezela ezizinzile, lawula ukucindezeleka kwefilimu bese uqinisekisa iphakethe eliphelele ngemva komjikelezo walo wokusatshalaliswa kwangempela kanye nokushisa.

Ukuvimbela Ukwehluleka Kokuvala Ithreyi Okulandelayo

Ukuvalwa kwethreyi okuthembekile kuncike ezinhlelweni ezine ezisebenza ndawonye:

Izinto ezihambisanayo + ama-flange ahlanzekile, ayisicaba + izilungiselelo zomshini olawulwayo + ukuqinisekiswa ngaphansi kwezimo zangempela zokusetshenziswa kokugcina.

Uma uxazulula inkinga, qala ngephethini yesici kunokulawula izinga lokushisa. Ukwehluleka kwethreyi ngayinye kukhomba ezintweni noma ekuqondeni; ukwehluleka endaweni eyodwa kukhomba ekusebenziseni amathuluzi; iziteshi ezingahleliwe zivame ukukhombisa ukungcola noma imibimbi; kanye nokwehluleka ngemva kokuqandisa noma ukufudumala kukhomba ekufinyeleleni kokusetshenziswa kokugcina.

Ukuze uthole ukwesekwa kobuchwepheshe, nikeza i-HSQY imininingwane noma amasampula ethreyi, isakhiwo se-lidding-film, imodeli yomshini, izithombe zesici, izilungiselelo zokukhiqiza kanye nokuziphatha okudingekayo kwe-peel. Lolu lwazi lwenza kube nokwenzeka ukuhlukanisa inkinga yefilimu kuthreyi, inkinga yamathuluzi noma yokucubungula ngaphambi kokuba kwenziwe i-oda eligcwele lokukhiqiza.
