Chikafu Packaging Roll Firimu Roll Otomatiki Packaging Machine Plastic Packaging Firimu

Firimu remubatanidzwa rakaumbwa kubva kune maviri kana anopfuura akaturikidzana anofanira kunge asina kupatsanurwa sefirimu rimwechete. Izvi zvinosanganisira zvinopfuura kungonamira pakati pemafirimu maviri. Zvakare zvine chekuita nefirimu reinki. Zvokunamira zvinhu zvekugadzira Mazhinji anonamira ane maviri-component polyurethane (PU) adhesives. Iyo kemikari inopindirana yekuchera inorapa iyo inonamatira. Iyo inonamatira pamusoro peiyo substrate inonyanya kuita kwemuviri uye chikamu chidiki chete ikemikari process. Panguva ino, zvikamu zvekunamatira zvinodonhedzwa pamwe chete nezvikamu mufirimu yepurasitiki uye zvinowedzera kuporeswa.
Kana firimu rinoumbwa rakatodhindwa panguva yekubatanidza maitiro ipapo iyo yekunamatira neingi inofanira kusangana nezvimwe zvinodiwa. Chinhu chakakosha chinodiwa ndechekuti mukati memukati unofanirwa kuve nekunamira kwakanaka kwekutsanya uye kuoma pamberi pelamination. Izvi zvinoreva kuti hapana zvisaririra zvesolvent zvinotenderwa mumucheka wakadhindwa. Asi zvinonyungudutsa kana doro zvinowanzosiiwa mubhainda reinki. Nokuda kwechikonzero ichi, zvinhu zvekunamatira zvinofanira kukwanisa kusunga kune mahara radicals (-OH mapoka). Zvikasadaro, iyo inonamira uye inorapa mumiriri ichaita yega uye inorasikirwa neyayo yekutanga zvivakwa.
Pakati pezvinonamira, zvinomisikidza-based adhesives zvinosiyaniswa kubva kune yakanyungudika-isina adhesives senge UV adhesives. Solvent-based drill musanganiswa inoda mugero wekuomesa kuti uvhure munyungudusi. Kana zvinonamirwa neUV zvichishandiswa, mwenje weUV unofamba nepakati pefirimu remubatanidzwa kuenda kunamatidza kuti polymerize chinonamira pamwechete.
1. Dry compound
Inoreva nzira iyo iyo yakanamatira inosanganiswa mumamiriro akaoma. Kutanga, iyo yakanamatira inoputirwa pane substrate. Mushure mekuoma mumugero wekuomeswa, zvose zvinonyungudutsa mukunamatira zvakaomeswa. Iyo nzira yekunyungudutsa iyo inonamira, kubatanidza imwe substrate kwairi, kutonhora, uye kurapa kuti ibudise inoumbwa zvinhu zvine zvinhu zvakanaka.
2. Extrusion compound
Iyo inozivikanwawo sekukanda musanganiswa, inova imwe yenzira huru dzekugadzira dzemukomboni flexible packaging. Iyo inonyungudutsa thermoplastics yakadai se polyethylene uye polypropylene mumushini we extrusion compounding, uye inoyerera kunze zvakafanana mufirimu yakatetepa kubva kumusoro wakatsetseka, uye inoramba yakaputirwa Panheyo yezvinhu, iyo inoumbwa firimu yezvikamu zviviri kana kupfuura inoumbwa nekutsikirira ne. chidzitiro chekumanikidza uye kutonhora nemhepo inotonhora.
Extrusion lamination ine zvakanakira kukurumidza kugadzira kukurumidza, nyore kugadzira maitiro, yakachena kugadzirwa nharaunda, yakakwira kugadzirwa kwekuita, kushanda kuri nyore, kudhura kwakaderera, uye hakuna zvinonyungudutsa zvinosara. nzvimbo inokosha.
