Kupisa kwakadzika kwekutanga kupfekedza firimurinogona kunge riri izwi rekutanga rawanzwa.Iwe unogona pakarepo kuve nekusahadzika, icho chigadzirwa chitsva here?Ko yakaderera tembiricha pre-kuputira firimu zvakafanana neinotonhora lamination firimu?Chii chakasiyanapasi-tembiricha adhesive firimuuye high-temperature adhesive film?
Rega EKO ipindure mibvunzo yako imwe neimwe.
Yakadzika tembiricha pre-yakaputira firimu haisi firimu rinotonhora rinopisa, uye rakakwezva kutarisisa kwakawanda mumunda wekushandisa weinotonhora laminating firimu kubva payakatangwa.Zvimwe zvinhu mufirimu inotonhora yelamination zvinowanzoita oxidation nekufamba kwenguva, zvichitungamira kune yero yemuviri wefirimu.Kunyanya kana yakaratidzwa kune chiedza chezuva kana kushandiswa kwenguva refu, dambudziko re oxidation kana yellowing rinonyanya kukosha.Cold laminating firimu inogonawo kukonzera matambudziko nekunamira kusina kukwana, senge mabhuru emhepo.Zvisinei, kutonhora kwepasi-pre-coating mafirimu ane mukana mukuru maererano nehutano uye mutengo.
Kubatsira kukuru kwemafirimu ekudziya kwepasi-kupisa kwemafirimu ndiko kuderera kwavo kwemusanganiswa tembiricha uye maitiro akaderera.Kuenzaniswa nemafirimu echinyakare akavharidzirwa anoda tembiricha yakakwira yemubatanidzwa, tembiricha inoumbwa yeakadzika-tembiricha pre coated mafirimu ingangoita 85 ℃ ~ 90 ℃, nepo akajairwa akavharidzirwa mafirimu anoda tembiricha yakasanganiswa ye100 ℃ ~ 120 ℃.Iyo yakaderera composite tembiricha inogona kudzivirira deformation uye kunyungudika kwezvinhu.Kuenzaniswa nemafirimu akajairwa ekutanga-kuputira, yakaderera-yekupfeka pre-kupfeka mafirimu akakodzera kune tembiricha inodzivirira zvinhu.Semuyenzaniso, PP advertising printing materials, PVC materials, thermosensitive paper, etc., pamwe necurling and edge warping issues kana uchishandisa akajairwa precoating films for adhesive labels, kushandiswa kweakadzika-tembiricha pre coating films inodzivirira kukuvara kwezvinhu kana kuparara kwemhando. zvinokonzerwa nekupisa kwakanyanya.
Chechipiri, iyo yakaderera-yekupisa pre-yakaputira firimu ine yakanakisa adhesion kuita.Pamusana pekuti iyo yakaderera-kupisa pre coating firimu haikuvadzi chimiro chechinhu panguva yekunyunguduka kweiyo adhesive layer, inogona kuwana yakachengeteka yakachengeteka bonding effect.Uyezve, nzira yekubatanidza yefirimu yakaderera-yakadzika pre-coating inokurumidza, pasina kudiwa kwenguva refu yekumirira, iyo inovandudza kushanda zvakanaka.
Mukuwedzera, iyo yakaderera-yekushisa pre-coating firimu zvakare ine kuchengetedzwa kwezvakatipoteredza kuita.Kuenzaniswa neyechinyakare coating,kuderera-kupisa pre coatinghaisununguri magasi anokuvadza panguva yekushandiswa.Mukutaura, iyo yakaderera-yekushisa Hot-melt adhesive firimu, ine zvakanakira yakaderera composite tembiricha, yakakwirira mutengo kuita, zvakanaka kuchinjika uye kuchengetedzwa kwezvakatipoteredza, yava sarudzo itsva kune vakawanda vatengi vane composite zvinodiwa.Mumaindasitiri akasiyana-siyana, yakaderera-tembiricha inonamira mafirimu ari kutyaira maitiro ekuvandudza uye kunyatsoita kuvandudza.Sarudza yakaderera-tembiricha firimu kuti uone kunaka kwezvigadzirwa zvako.
