Metalized thermal lamination filminoumbwa inochinjika yekurongedza zvinhu inoumbwa nekushandisa yakakosha nzira yekupfekedza pamusoro pefirimu repurasitiki neakanyanya kutetepa simbi yealuminium, iyo inonyanya kushandiswa nzira yekugadzira vacuum aluminium plating nzira, kureva, simbi aluminium inonyungudika. uye inoputika pakupisa kwepamusoro munzvimbo yakakwirira yevacuum, kuitira kuti mhute inonaya yealuminium inoisa pamusoro pefirimu repurasitiki, kuitira kuti pamusoro pefirimu repurasitiki rive nesimbi inopenya.Nekuti ine ese maficha epurasitiki firimu nesimbi, yakachipa uye yakanaka, yakanakisa kuita uye inoshanda yekurongedza zvinhu.
Pazasi pane kuita kwayo:
1.Chitarisiko
The pamusoro pemetalized pre-coating filminofanira kuva yakadzikama uye yakatsetseka, isina makwinya kana kuti zvishoma chete zvipenyu zvipenyu;hapana zvakajeka zvisina kuenzana, tsvina uye zvidhinha zvakaoma;hapana mavanga, mabubbles, maburi nezvimwe zvirema;usabvumira kupenya kwakajeka, Yin uye Yang pamusoro uye zvimwe zviitiko.
2.Kukora kwefirimu yesimbi
Ukobvu hwealuminized kupisa laminating firimu kunofanira kuva yunifomu, ukobvu kutsauka kweinochinjika uye longitudinal kunofanira kuva diki, uye kutsauswa kuparadzirwa kwakawanda yunifomu.Hapana mbabvu inoonekera padhiramu, zvikasadaro zviri nyore kuunyana kana uchinge uchirasa.
3.Kukora kwealuminium coating
Ukobvu hweiyo aluminium coating yakanangana neiyo barriers pfuma yemetalized composite film.Nekuwedzera kwekukora kwealuminium coating, kufambiswa kweokisijeni, mhute yemvura, mwenje, nezvimwewo, zvishoma nezvishoma zvinodzikira, uye zvinoenderana, iyo inovharira pfuma yealuminium plating firimu inovandudzwa zvakare.Nokudaro, kukora kwealuminium coating kunofanira kusangana nezvinodiwa, uye kuvhara kunofanira kuva yunifomu, zvikasadaro hazvizokwanisi kuita zvinotarisirwa.
4.Kunamatira
Iyo aruminiyamu yekuputira inofanirwa kuve yakasimba adhesion uye yakanaka kusimba, zvikasadaro zviri nyore kuita dealuminize uye kukonzera matambudziko emhando.Mukuita kwemhando yepamusoro vacuumaluminium laminating firimu, imwe chiyero cheprimer glue inofanira kuiswa pamusoro pearuminiyamu pamusoro pealuminium base firimu kutanga kuvandudza simba rekubatanidza pakati pealuminium coating ne substrate film, kuitira kuti ive nechokwadi chekuti aluminium coating yakasimba uye haisi nyore kudonha. .Zvadaro, iyo aluminium plating layer inofanirawo kuputirwa ne-two-component polyurethane adhesive sechinhu chepamusoro kuchengetedza aluminium plating layer kuti isasakara.
5.Physical uye mechanical properties
Themetalized thermal laminating filminoiswa pasi pesimba remagetsi panguva yemubatanidzwa, saka zvinodikanwa kuve neimwe simba remuchina uye kuchinjika, uye inofanirwa kuve neyakagwinya simba, kureba, kubvarura simba, simba rekuita, yakanakisa kupeta kuramba uye kuoma uye zvimwe zvivakwa kuti ive nechokwadi chekuti. haisi nyore kukanya, kuputsika, kutsemuka uye zvimwe zviitiko panguva yekugadzira composite.
6.Moisture permeability
Moisture transmittance inoratidza kupera kwealuminium EVA adhesion firimukumhute yemvura pasi pemamwe mamiriro, ayo anoratidza kunyorova kwealuminium thermal laminating firimu kune imwe nhanho.Semuyenzaniso, mwando permeability ye12 um polyester metalized kupisa lamination firimu (VMPET) iri pakati 0.3g /㎡·24h ~ 0.6g /㎡·24h (tembiricha 30℃, hama mwando 90%);The mwando permeability yeCPP aluminized firimu (VMCPP) ine ukobvu hwe25 um iri pakati pe1.0g /㎡·24h uye 1.5g /㎡·24h (tembiricha 30℃, humidity 90%).
7.Oxygen permeability
Oxygen permeability inomiririra kuwanda kwekupinzwa kweokisijeni yealuminium thermal lamination film pasi pemamwe mamiriro ezvinhu, ayo anoratidza hukuru hwechivharo chemetalized thermal lamination film to oxygen, senge oxygen permeability yepolyester aluminium pre-coating film ine ukobvu. ye25 um ingangoita 1.24 ml/㎡·24h (tembiricha 23℃, hunyoro hunoenderana ne90%).
8.Ukuru hwekutambudzika kwepamusoro
Kuti uite inki uye inosanganiswa yekunamira kuve nekunyorova kwakanaka uye kunamatira pamusoro pearuminiyamu inoumbwa firimu, zvinodikanwa kuti kushushikana kwepamusoro kwesimbi yakavharwa firimu kunofanirwa kusvika kune imwe mwero, zvikasadaro ichakanganisa kunamatira uye. kunamatira kweinki uye kunamira pamusoro, zvichikanganisa kunaka kwechinhu chakadhindwa uye zvigadzirwa zvinosanganiswa.Semuenzaniso, kushushikana kwepamusoro kwepolyesteraluminium thermal lamination film(VMPET) inodiwa kuti isvike kupfuura 45 dynes, angangoita 42 dynes.
Kuti uwane rumwe ruzivo nezve thermal lamination firimu, ndapota ramba uine ziso pane yedu webhusaitihttps://www.ekolaminate.com/
