Ukuntu Ubushuhe Bwiza Bwiza Bugira ingaruka kuri Lacquer Adhesion kuri Fayili Yapakishijwe Aluminium

Mu bikoresho bya kijyambere byoroshye kandi bigizwe na aluminiyumu - nk'ibipaki bya farumasi ya farumasi, yogurt yogurt, retort pouches, hamwe n'ibikoresho byabigenewe - lacquers zo gukingira no gushushanya zikoreshwa mu ifu ya aluminiyumu yoroheje ($ 6 inyandiko {kugeza} 100 , mu inyandiko {m} $) igomba kwihanganira uburyo bukomeye bwo gukora imashini, gushushanya cyane, gufunga ubushyuhe, no guhagarika imiti.

Ubusugire bwiyi barrière biterwa lacquer gufatira kuri substrate ya aluminium. Mugihe ubuso bwambere bwo kuvura hamwe nubushyuhe bukabije nibintu byingenzi byingenzi, ikintu kimwe cyingenzi cyo gutunganya ibintu byerekana imbaraga zigihe kirekire hagati yumubano nigihe cyo gukiza ubushyuhe (isano iri hagati yubushyuhe bwa Peak Metal, igihe cyo gutura, nigipimo cyumuriro).

Shingiro ryo Kuvura Ubushuhe kuri Coated Urupapuro rwa aluminiyumu

Gukoresha lacquer y'amazi (solvent-borne cyangwa water-water) kuri fayili ya aluminium ikubiyemo ibyiciro bibiri bitandukanye byumubiri na chimique: ibiyobora-shoferi hamwe na polymer . Ubushyuhe bukiza butanga imbaraga zo gukora zisabwa kugirango iyi nzira irangire.

Amashanyarazi yohereza ingufu

Imirongo ikomeza ya coil ikoresha uburyo butatu bwambere bwo kohereza ubushyuhe muri aluminiyumu yoroheje:

Amashyiga yo mu kirere ku gahato: Umuyaga mwinshi ushyushye wohereza ingufu zumuriro hejuru yubuso hamwe na substrate ya foil.

Amashyiga hafi-ya-Infrared (NIR) & Far-Infrared (IR): Imirasire ya electromagnetique itera molekile ya resin kama kandi igashyushya ifu iri munsi, bikagabanya uburebure bwa tuneli bukenewe.

Gushyushya Induction: Imirima ya electromagnetique itanga amashanyarazi imbere muri fayili ya aluminiyumu, gushyushya substrate imbere. Ibi bitwara ibishishwa hanze bitarinze uruhu rwo hejuru.

Umuyoboro uhinduka Kinetics vs Kwambukiranya imipaka

Ubushyuhe bwumuriro bugomba kuba bwubatswe kugirango birinde uruhu rwo hejuru - imiterere aho urwego rwo hejuru rwo gutwikira rukiza imburagihe, rufata imishwarara ihindagurika munsi yacyo.

Niba igipimo cyo gushyushya ubushyuhe ( Δ T / Δ t) kirahanamye cyane mbere yuko flash-off ya mbere irangira, umutego wafashwe wumuyaga uhuha cyane mubushyuhe bwo hejuru, ugakora pinholes, micro-blistes, hamwe nimbibi zidafite aho zihurira na foil-lacquer.

Imbonerahamwe ikurikira irerekana ibipimo bisanzwe byo gukiza bya aluminiyumu bipfunyika foil lacquer hamwe nubucuruzi bukora:

Kwipimisha & QA Uburyo bwo Kugenzura Lacquer Adhesion Kugenzura

Kugenzura niba imyirondoro ikiza ubushyuhe itanga imikorere isabwa yo gufatira hamwe, ibihingwa bitwikiriye bikoresha ibizamini byangiza kandi byisesengura.

Ibibazo

Q1: Kuki lacquer itandukana na fayili ya aluminium mugihe cyo gufunga ubushyuhe?

Igisubizo: Gusiba mugihe cyo gufunga ubushyuhe mubisanzwe bibaho kubera ko primer / lacquer yibanze yari itarakize neza (ubucucike buke bwambukiranya imipaka itera kunanirwa gufatana iyo hashyushye) cyangwa gukira cyane (ubushyuhe bukabije bwumuriro bwatumaga umwenda ucika intege, bigatuma bogosha munsi yigitutu cya kashe).

Q2: Ni irihe tandukaniro riri hagati yubushyuhe bwikirere bwitanura nubushyuhe bwa Peak Metal (PMT)?

Igisubizo: Ubushyuhe bwo mu kirere ni ubushyuhe bwibidukikije imbere yubushyuhe, mugihe PMT nubushyuhe ntarengwa bwageze kuri aluminium foil ubwayo. Kuberako ihererekanyabubasha riterwa numuvuduko wumurongo, uburebure bwa fayili, n umuvuduko wumwuka wumuyaga, PMT igomba gupimwa ukoresheje thermocouples ikurikirana cyangwa pyrometrike ya IR.

Q3: Nigute impagarike ya aluminiyumu (urwego rwa dyne) igira izihe ngaruka ku gukiza ubushyuhe?

. Igisubizo Kuvomera neza bituma igipfundikizo gitemba muri topide ya oxyde mbere yo gukira, bigabanya imiti n’imashini bimaze gukira.

Q4: Gukiza ubushyuhe birashobora kugira ingaruka kumbaraga cyangwa ubushyuhe bwa feri ya aluminiyumu?

Igisubizo: Yego. Kugaragaza ifu ya aluminiyumu ikonje (urugero, ubushyuhe bwa H18) kuri profili ndende ya PMT (> 200 ° C) mugihe kirekire gishobora gutera annealing igice cyangwa gukira, bikagabanya gato imbaraga zingana mugihe byongera kuramba. Gukiza inzinguzingo bigomba kubarwa kugirango bibungabunge ibikoresho bya substrate bikenewe.

Q5: Nigute Changzhou Dingang Metal Material Co., Ltd. (Ubushinwa) yemeza ko lacquer imwe ihuza ibishishwa byinshi?

Igisubizo: Dingang Metal Material Co., Ltd ikoresha imashini ifunze-ifunguye PMT yerekana ubugari bwumugozi wose, iherekejwe nubutaka bwa corona mbere yo kuvurwa hamwe na sisitemu yo kugenzura uburemere bwamakoti kugirango harebwe imikorere ihamye kuva kumpande kugera hagati.

Umwanzuro

Gutezimbere ubushyuhe bukiza ningirakamaro kubyara umusaruro imikorere-yimikorere ya lacquered aluminium ipakira . Mugutondekanya neza Ubushyuhe bwa Peak Metal, igihe cyo gutura mu ziko, hamwe nogukora ibintu bigenda byangirika, abahindura hamwe nabapakira ibicuruzwa birashobora kwemeza ko lacquer ihambiriye, gukurura cyane, hamwe no gukumira inzitizi zikomeye zo kwirinda ibicuruzwa byuzuyemo ibintu hamwe nuburyo bwo kuboneza urubyaro.
