Polyethylene (PE) firimu chinhu chakatetepa, chinochinjika chakagadzirwa kubva ku polyethylene polymer chinoshandiswa zvakanyanya kurongedza, kudzivirira, uye zvimwe zvikumbiro.Iyo nzira yekugadzira ye polyethylene firimu inogona kukamurwa zvakafara mumatanho akati wandei:
- Kugadzirwa kweresin: Danho rekutanga mukugadzira kugadzirwa kweiyo mbishi, inova mhando yepolyethylene resin.Izvi zvinoitwa kuburikidza nepolymerization, chimiro chemakemikari chinogadzira cheni refu dzepolymer mamorekuru kubva kumamonomers senge ethylene.Resin yacho inobva yaiswa pellet, yakaomeswa, uye inochengetwa kuti iwedzere kugadziriswa.
- Extrusion: Nhanho inotevera ndeyekushandura resin kuita firimu.Izvi zvinoitwa nokupfuudza resin kuburikidza neextruder, muchina unonyungudisa resin woimanikidza nepaburi duku rinonzi die.Iyo yakanyungudutswa resin inotonhora pasi uye inoomesa sezvainowedzerwa, ichigadzira pepa rinoenderera refirimu.
- Kutonhodza uye mhepo: Mushure mekunge firimu rawedzerwa, rinotonhodzwa kusvika kune tembiricha yekamuri uye kukuvadzwa pamupumburu.Iyo firimu inogona kutambanudzwa uye inotungamirwa panguva iyi, iyo inovandudza maitiro ayo emagetsi uye inoita kuti ive yakafanana.
- Calendering: Iyo firimu inogona kufambiswazve kuburikidza nenzira inonzi calendering, iyo inopfuudzwa nepakati peseti yeanodziya rollers kugadzira nzvimbo yakatsetseka uye inopenya.
- Lamination: Iyo firimu inogona kusanganiswa nezvimwe zvinhu kuti iite laminated chimiro.Izvi zvinowanzoitwa nekushandisa adhesive layer pakati pezvikamu zviviri kana kupfuura zvefirimu, izvo zvinopa zvakagadziridzwa zvipingamupinyi zvinhu uye zvinowedzera kushanda kwechigadzirwa chekupedzisira.
- Kudhinda nekucheka: Chigadzirwa chekupedzisira chemufirimu chinogona kudhindwa nemaitiro anodiwa kana magirafu, uye wozocheka muhukuru hunodiwa uye chimiro chekushandisa chaiko.
Aya matanho anogona kusiyana zvichienderana nezvinodiwa zvivakwa uye magumo-ekushandisa mashandisirwo emufirimu wepolyethylene, asi maitiro ekutanga anoramba akafanana.
