Mumunda wezvigadzirwa zvemazuva ano zveindasitiri, firimu remuchinjika rave sarudzo yakakosha kune akawanda maindasitiri nekuda kweakanakisa zvimiro zvemuviri uye yakafara application mamiriro. Ingave iri kuvaka kusapinda kwemvura, kurongedza zvinhu kana zvemagetsi chikamu chekudzivirira, firimu remuchinjika rinofarirwa nekuda kwesimba rayo repamusoro, kuramba kwemamiriro ekunze uye kugadzikana. Ichi chinyorwa chichaongorora zvakadzama mafambiro emuchinjika firimu kubatsira vaverengi kuve nekunzwisisa kwakadzama kwemaitiro ekugadzirwa kwechinhu chakakosha ichi.
Kugadzirwa kwemuchinjika firimu kunotanga nekusarudzwa uye kuenzanirana kwezvinhu zvakabikwa. Kazhinji, high molecular polymers anoshandiswa sezvigadziko zvekushandisa, zvakadai se polyethylene (PE), polypropylene (PP) kana polyester (PET), uye zvinowedzera zvakadai seUV inhibitors, antioxidants kana plasticizers zvinowedzerwa maererano nezvinodiwa zvekushandisa kuvandudza kushanda kwefirimu. Mushure mekuita metering chaiyo, zvigadzirwa zvinopinda muchina wekusanganisa kuti ive nechokwadi chekugovera yunifomu yezvigadzirwa, nekuisa hwaro hwekuzotevera kugadzirisa.
Nhanho inotevera ndeye extrusion molding. Mishonga yakavhenganiswa inodziiswa kuti inyunguduke neextruder yoiswa mumashizha matete kuburikidza neT-die. Mukuita uku, kutonga kwekushisa uye kumanikidza kwakakosha, izvo zvinokanganisa zvakananga kukora uye kupfava kwepamusoro kwefirimu. Iyo firimu yakanyungudutswa yakanyungudutswa inobva yapinda muboka rekutonhodza roller, inokurumidza kuumba, uye inoita yekutanga firimu chimiro.
Mushure mekutonhora, iyo firimu inopinda munhanho yekutambanudza, inova nhanho yepakati yemuchinjikwa firimu process. Iyo firimu inotanga kutambanudzwa kureba, ndiko kuti, kushushikana kunoshandiswa munzira imwe chete kurongedza cheni dzemamorekuru munzira yekutambanudza, nekudaro ichivandudza kusimba uye kugadzikana kwechidimbu chefirimu. Mushure meizvozvo, iyo firimu inotambanudzwa yakachinjika, kazhinji pakupisa kwepamusoro, kurongazve maketani emokuru mune imwe nzira, ichigadzira biaxially yakatambanudzwa chimiro. Iyi biaxial kutambanudza maitiro inopa iyo muchinjiko firimu yakanakisa michina zvivakwa uye kupisa kuramba.
Iyo firimu yakatambanudzwa inodawo kurapwa pamusoro, senge corona kurapwa kana coating, kuti iwedzere kudhinda kwayo kana kunamatira kune zvimwe zvinhu. Chekupedzisira, iyo firimu inotsemurwa, yakakungurutswa uye mhando yakaedzwa kuti ive nechokwadi chekuti imwe neimwe roll yechigadzirwa inosangana nezvinodiwa.
Maitiro ekugadzira emuchinjika firimu anosanganisa polymer zvinhu sainzi, mechanic engineering uye mhando yekudzora tekinoroji, uye kuoma kwayo uye nemazvo zvinotaridza kuita kwechigadzirwa chekupedzisira. Nekuenderera mberi kwekufambira mberi kwetekinoroji, iyo ndima yekushandisa yemuchinjikwa firimu ichawedzerwazve kuti ipe mhinduro dzakasimba kumaindasitiri akasiyana.
