Ukulawulwa kokuvuthwa: ukuvuthwa kubizwa nangokuthi ukuphulukisa, kuyinqubo yokubeka ifilimu ehlanganiswe kuhhavini (igumbi lokuvuthwa), ukuze i-ejenti eyinhloko ye-polyurethane adhesive, ukuphulukisa i-agent reaction crosslinking futhi ihlanganiswe ne-substrate surface interaction. .Inhloso eyinhloko yokwelapha ukwenza i-ejenti eyinhloko kanye ne-ejenti yokwelapha esikhathini esithile ukuze isabele ngokugcwele ukuze kuzuzwe amandla ahlanganisiwe angcono kakhulu;okwesibili, ukususa iphuzu eliphansi lokubilisa lensalela ye-solvent, njenge-ethyl acetate, njll.
Ukulawula ukuvuthwa ngokuyinhloko ukulawula izinga lokushisa lokuvuthwa kanye nesikhathi sokuvuthwa.Isikhathi sokuvuthwa sokushisa kokuvuthwa sinqunywa ukusebenza kwe-adhesive esetshenzisiwe kanye nezidingo zokugcina zokusebenza komkhiqizo.Izinhlobo ezahlukene ze-binder zinamazinga okushisa ahlukene okuvuthwa kanye nezikhathi.Izinga lokushisa lokuvuthwa liphansi kakhulu, lingaphansi kuka-50 ℃, ukusabela kwe-adhesive kuhamba kancane kakhulu;izinga lokushisa lokuvuthwa liphezulu kakhulu, i-substrate ifilimu izithasiselo zezulu, ithinta ukusebenza kwefilimu eyinhlanganisela futhi yandise iphunga, njengokuthi isikhathi sokuvuthwa side kakhulu izophinde ithinte ukusebenza kwefilimu eyinhlanganisela futhi yandise iphunga, elibangelwa ikakhulukazi imvula yokucubungula. izinsiza kufilimu ye-polyethylene.
Umsebenzi wegumbi lokuvuthwa: Ukubeka ifilimu ehlanganiswe ekamelweni lokubhaka (igumbi lokuvuthwa), ukuze i-adhesive eyinhloko ye-polyurethane enamathelayo, i-ejenti ephulukisayo yokusabela kwe-cross-linking futhi ihlanganiswe inqubo yokusebenzisana kwe-substrate. .Inhloso eyinhloko yokuvuthwa ukwenza i-ejenti eyinhloko kanye ne-ejenti elaphayo isabele ngokugcwele phakathi nenkathi ethile yesikhathi ukuze kuzuzwe amandla ahlanganisiwe angcono kakhulu;okwesibili, ukususa ama-solvents asele ngephuzu eliphansi lokubilisa, njenge-ethyl acetate, njll., ukunciphisa inani lensalela ye-solvent nokunciphisa iphunga.
Izimo zokuvuthwa nazo zincike ezintweni ezilandelayo.
I-1, i-PET, i-BOPA, i-AL, i-CPP namanye amafilimu ngenxa yokumelana nokushisa okuhle, izinga lokushisa eliphezulu lokuncipha, izinga lokushisa lokuvuthwa lingakhuphuka.Futhi i-LDPE, BOPP, EVA kanye nezinye izinga lokushisa lokuvuthwa alikwazi ukuphakama kakhulu;isimo esijwayelekile 50 ℃ - 65 ℃ phakathi.
2, Isikhathi sokuvuthwa semikhiqizo enenani eliphezulu leglue side.
I-3, Isikhathi sokuvuthwa semikhiqizo ngendlela yama-movie rolls singancishiswa ngokufanele.
I-4, Isikhathi sokuvuthwa semikhiqizo enezintambo ze-convex ze-longitudinal singandiswa.
5, ukushuba ifilimu, ifilimu roll ububanzi uma kufanelekile ukunweba isikhathi nokuvuthwa.
6, ukuze kuncishiswe inani le-solvent eyinsalela inganwetshwa ngokufanele isikhathi sokuvuthwa.
I-7, ngokusho kokusetshenziswa komkhiqizo ukulungiswa okufanele kwesikhathi sokuvuthwa.
Kukhona futhi ukuvuthwa okusheshayo ukulawula ekukhiqizeni.Thatha ifilimu eyinhlanganisela esanda kukhiqizwa cishe imitha eyi-1 ubude, ububanzi obugcwele, ibekwe kuhhavini ngama-degree angu-80 imizuzu engu-30, ekuhloleni ukubukeka kwayo kanye nesimo sokuqala sokuxebuka kwe-viscosity, ukutholakala ngesikhathi kwezinkinga nezinyathelo.Lokhu kuphinde kube yingxenye ebalulekile yokulawulwa kwenqubo yokomisa i-lamination.
Kunezidingo ezilandelayo zegumbi lokuvuthwa.
I-1, ubukhulu kanye nendawo yegumbi lokuvuthwa kufanele kwakhiwe ngokuvumelana nokulula kwesitoreji senzuzo, ukuze kube lula ukungena nokuphuma kwe-roll yefilimu, umnyango kufanele uvuleke kalula.
2, ukuphakama kwegumbi lokuvuthwa kuvame ukungamamitha angama-2-2.5, phezulu kube umbhoshongo, kushiya imigodi engu-5-10 cm phezulu, kungaba ngaphandle ngqo, noma wengeze iwindi elincane lokukhipha umoya njalo, indima iwukuba khipha iphunga legumbi lokuvuthwa.
3, amashalofu egumbi lokuvuthwa angabekwa uhlobo lweshalofu oluyisicaba noma olunezinhlangothi ezintathu, kuye ngezimo zokuthutha zebhizinisi ngalinye, kodwa hhayi umqulu wefilimu ngokuqondile noma olele phansi.
I-4, izindonga ezine zegumbi lokuvuthwa, iminyango, uphahla kanye nokunye ukwahlukanisa, ngokuvamile kusetshenziswa i-perlite, ibhodi legwebu, njll., umphumela uwukwandisa isikhathi sokufakelwa, ukonga ugesi, ukunciphisa izindleko kanye nezinga lokushisa elizungeze okufanayo.
5, Ukulawula ukushisa.Igumbi lokuvuthwa lingashiswa ngogesi, umusi, ukushisa, njll., kungakhathaliseki ukuthi hlobo luni lokushisa, kufanele lifakwe amadivaysi okushisa okushisa, ekamelweni kufanele kube yi-mercury thermometer ukuhlola ukuthi izinga lokushisa bese usetha okufanayo.
I-Guangdong Lebei Packing Co., Ltd.uphumelele izitifiketi ze-QS, SGS, HACCP, BRC, ne-ISO.Uma ufuna ukwazi okwengeziwe futhi uhlose uku-oda izikhwama, sicela usithinte.Sizokunikeza isevisi enhle kanye nentengo evumayo.
