Inonyanya kuzivikanwa sePOLYVINYL CHLORIDE FILM, inogadzirwa nePVC resinuye mamwe ma modifiers necalendering process kana blow molding process.Ukobvu huzhinji ndeye 0.08~ 0.2mm, yakakura kupfuura 0.25mm inonzi PVC sheet.PVC resin yakawedzera plasticizer, stabilizer, lubricant uye mamwe anoshanda kugadzirisa AIDS, calendering firimu.

Rudzi urwu rwekudururwa firimu rekuchengetedza kupisa, mwenje transmittance yakanaka, yakapfava uye iri nyore kuumba, yakakodzera girinhi, greenhouse uye diki rakateurwa rekunze rekuvhara zvinhu.

Zvakaipa ndezvi: chikamu chefirimu chakaderera, mari yakakwirira;Kusagadzikana kwemamiriro ekunze, kuoma uye brittle pakupisa kwakadzika, nyore kupfava uye kusunungura pakupisa kukuru;Mushure mekunaya kwezvinowedzera, iyo firimu pamusoro pekutsvaira, inokanganisa kutapurirana kwechiedza;Residual firimu haisi degradable uye kupisa kurapwa.

PVC Firimu rinogona kukamurwa kuita zvikamu zviviri, imwe iPlasticized PVC Firimu, inozivikanwawo seyakapfava PVC Firimu (Plasticized PVC Firimu), imwe yacho isiri Plasticized PVC Firimu, inozivikanwawo seyakaoma PVC Firimu (Unplasticized PVC Firimu) Pakati pavo, yakaoma PVC maakaunzi anosvika 2/3 yemusika, uye anochinjika PVC maakaundi e1/3.

PVC yakapfava inowanzoshandiswa pasi, sirin'i uye nedehwe pamusoro, asi nekuti yakapfava PVC ine softener (uyu ndiwowo mutsauko pakati pePVC yakapfava uye yakaoma PVC), iri nyore kuita brittle, isiri nyore kuchengetedza, saka kushandiswa kwayo kunogumira Zvakaoma. PVC haina kunyorovesa agent, saka kuchinjika, kuumbwa kuri nyore, kwete brittle, isina-chepfu kusvibiswa-isina, kuchengetedza nguva yakareba, saka kusimudzira uye kushandiswa kwekukosha kukuru kwePVC firimu ndiko musimboti wevacuum blister film, inoshandiswa marudzi ese epanel surface layer yekurongedza, inozivikanwawo seyekushongedza firimu Natanidza firimu, rinoshandiswa mukuvaka zvinhu zvekurongedza mishonga, uye mamwe akawanda maindasitiri Indasitiri yezvivakwa zvekuvaka yakaverengera chikamu chikuru, 60%, ichiteverwa neindasitiri yekurongedza, kune akati wandei mamwe madiki mashandisirwo eindastiri maererano nefirimu rinogadzira raw materials classification: polyethylene film, polypropylene film, PVC film and polyester film Zvinoenderana nefirimu rekushandisa kupatsanura: firimu rekurima (pano maererano nekushandiswa chaiko kwefirimu rekurima, rinogona kukamurwa kuita mulching firimu uye greenhouse film);Kurongedza firimu (kurongedza firimu zvinoenderana nezvinangwa zvavo, uye rinogona kukamurwa kuita chikafu chekurongedza firimu uye marudzi ese ezvigadzirwa zvemaindasitiri zvine firimu rekurongedza, nezvimwewo) uye rinoshandiswa munzvimbo yakakosha Breathable firimu rine maUSES akakosha, firimu rinonyungudika nemvura uye rine. kuita kwepiezoelectric yakaonda firimu uye zvichingodaro Maererano nekugadzira nzira dzeiyo firimu classification: extrusion plasticizing Wobva wafuridza molding yefirimu yakaonda, inonzi firimu rinoputika;Mushure extrusion plasticizing, uye ipapo yakanyungudutswa zvinhu kubva chakuvhe muromo kuyerera kuwedzera kuumba firimu, inonzi kuyerera kuwedzera firimu;Firimu rakagadzirwa nemidziyo yepurasitiki yakakungurutswa nema roller akati wandei pacalender inonzi calendered film.
