Izizathu nezisombululo ezithinta ukungafihli kwetheyiphu yokuvikela ye-aluminium

Ukukhetha okungalungile kokunamathela

Uma okunamathelayo kunombala mnyama noma kunoketshezi olunganele, ukusebenza kokulinganisa kungaba ngcono futhi kusatshalaliswe ngokugcwele kutheyiphu yokuvikela elaminethiwe ye-aluminium. Ngokuvamile, ukuphakama kokuqukethwe okuqinile kokunamathelayo okuholayo, kulapho uketshezi luba ngcono khona ekusabalaleni kwefilimu. I-75% yeglue ingcono kune-50% yomphumela osobala, futhi i-50% ingcono kune-40% noma i-35% yeglue. Ukufaka izinto zokunamathisela ngo-50% no-40% kuyinselele kutheyiphu yokuvikela ye-aluminium enezidingo eziphezulu zokubonisa izinto.

Izinkinga ohlelweni

Okokuqala, izinga lokushisa lomgudu wokubhaka we-laminator liphezulu kakhulu; ukomisa kuyashesha kakhulu, i-solvent yongqimba olungaphezulu lweglue iyaguquguquka (ukuhwamuka), i-glue surface crusts kusenesikhathi kakhulu, khona-ke lapho ukushisa kungena ngaphakathi kwesendlalelo seglue, i-solvent engezansi kwefilimu yeglue izoba ngumusi, lapho igesi igijima ebusweni befilimu yeglue ukuze yakhe intaba-mlilo efana ne-crater, indilinga yamasongo, okwenza ungqimba lweglue lungabonakali ngokwanele. Okwesibili, uma i-roller yokucindezela ehambisanayo noma i-scraper ineziphambeko, iphuzu elithile lokucindezela aliqinile, futhi ukwakheka kwesikhala kuzophinde kubangele ifilimu ngemva kokuba ukuthobela kungabonakali.

Lapha ukujoyina indawo yokusebenza yomoya othulini kuningi kakhulu; ngemva kokunamathisela umoya oshisayo owamunca esiteshini sokumisa, kukhona nothuli olunamathela ebusweni bongqimba olunamathelayo noma oluyinhlanganisela lapho luhlanganiswe phakathi kwezingqimba ezimbili zefilimu eyisisekelo, uthuli oluningi olubangelwa ukufiphala noma ukungafihli kahle.

Isixazululo umshini ovaliwe we-laminating engxenyeni yeglue, ukomisa indawo yokungenisa umoya wesiteshi enenani eliphakeme le-mesh yezihlungi, ukuvimbela uthuli olufakwe ngaphakathi (okungukuthi, sula isiteshi sokumisa umoya oshisayo othulini).

Ngaphezu kwalokho, ayikho i-roller yokusabalalisa, noma i-roller yokusabalalisa ayihlanzekile; kuzokwenza ifilimu ngemuva kokuba i-composite ingashintshi ngokwanele, noma inhlanganisela enani leglue alanele, izikhala zeglue ezingalingani, ifolda enamabhamuza amancane, okuholela kumabala noma i-opaque.

Isixazululo ukuhlola nokulungisa inani leglue ukuze lanele futhi liboshwe ngokulinganayo, okuholela kulokho okuvame ukubizwa ngokuthi "ifilimu yobuso be-hemp."

Ezinye Izinkinga

Kumele kuqashelwe ukuthi izinga lokushisa le-laminating hot drum aliphezulu ngokwanele, ingxenye eshisayo encibilikayo ye-adhesive ayincibiliki, izinga lokushisa le-roller yokupholisa liphezulu kakhulu, futhi akunakwenzeka ukulipholisa ngokuzumayo, konke okungaholela ekutheni ifilimu ingabonakali obala.

Isixazululo: izinga lokushisa lesigubhu esishisayo akufanele libe ngaphansi kuka-70 degrees; ingxenye encibilikayo eshisayo yejeli izoqala ukuncibilika kuphela lapho izinga lokushisa lifinyelela ku-65 degrees; ngemva kokuncibilika, akukhona nje kuphela ukuthi ukucaca kuzothuthukiswa, kodwa futhi ukuqina kwenhlanganisela kuzokwanda. Ama-roller okupholisa kufanele apholiswe ngamanzi apholile noma ukujikeleza kwamanzi abandayo; lapho isivinini sokupholisa sishesha, ngcono ukubonakala, kungcono ukucaba kwefilimu eyinhlanganisela, futhi kube ngcono ukuqina.
