application

POLYVINYL CHLORIDE FILM, inogadzirwa nePVC resinuye mamwe ma modifiers kuburikidza necalendering process kana blow molding process.Ukobvu huzhinji ndeye 0.08 ~ 0.2mm, yakakura kupfuura 0.25mm inonzi PVC sheet.Plasticizer, stabilizer, lubricant uye mamwe maitiro ekugadzirisa AIDS anowedzerwa kuPVC resin, uye iyo firimu inoumbwa necalendering.

PVC Firimu rinogona kukamurwa kuita zvikamu zviviri, imwe iPlasticized PVC Firimu, inozivikanwawo sePVC Firimu yakapfava, imwe yacho Unplasticized PVC Firimu, inozivikanwawo seyakaoma PVC Firimu.

Pakati pazvo, yakaoma PVC accounts inosvika 2/3 yemusika, uye yakapfava PVC account ye1/3.PVC yakapfava inowanzo shandiswa pauriri, sirin'i uye pamusoro pematehwe, asi nekuti yakapfava PVC ine softener (uyu ndiwowo mutsauko pakati pePVC yakapfava uye yakaoma PVC), iri nyore kuita brittle, isiri nyore kuchengetedza, saka huwandu hwayo hwekushandisa hushoma. .Hard PVC haina softener, saka ine yakanaka kuchinjika, nyore kuumba, isiri nyore crisp, isiri-chepfu uye isina kusvibiswa-isina, yakareba kuchengetedza nguva, saka ine budiriro yakakura uye kukosha kwekushandisa.Iyo yakakosha yePVC firimu ivacuum blister firimu, rinoshandiswa kurongedza pamusoro pemarudzi ese emapaneru, saka inozivikanwa zvakare seyekushongedza firimu, inonamira firimu, inoshandiswa mukuvaka, kurongedza, mushonga uye mamwe maindasitiri mazhinji.Pakati pavo, indasitiri yezvivakwa zvekuvaka inoverengera chikamu chikuru che60%, ichiteverwa neindasitiri yekurongedza, kune akati wandei mamwe madiki mashandisirwo eindastiri.

⑴ Zvinoenderana neyakagadziriswa inoshandiswa kugadzira firimu: polyethylene firimu, polypropylene firimu, polyvinyl chloride firimu uye polyester firimu.

(2) Kurongeka nekushandiswa kwemafirimu: firimu rekurima (pano maererano nekushandiswa chaiko kwefirimu rekurima, rinogona kukamurwa kuita firimu repurasitiki uye greenhouse film);Packaging firimu (PACKAGING firimu maererano nemashandisirwo ayo chaiwo, uye inogona kukamurwa kuita chikafu chekurongedza firimu uye akasiyana maindasitiri zvigadzirwa zvekurongedza firimu, nezvimwewo) uye kune yakasarudzika nharaunda, nekushandiswa kwakakosha kwefirimu rinofema, firimu rinonyungudika nemvura uye piezoelectric zvimiro zvefirimu. .

(3) Maererano firimu kuumba nzira classification: extrusion plasticization, uye ipapo kuridza kuumbwa firimu, inonzi pfuti kuumba firimu;Mushure extrusion plasticization, uye ipapo zvakanyungudutswa zvinhu zvinoyerera kubva mold muromo kugadzira firimu, inonzi kuyerera firimu;Mumuchina wecalendering nemapumburu akati wandei akakungurutswa zvinhu zvepurasitiki zvakagadzirwa nefirimu, inonzi calendering firimu.

Kushandiswa kwePVC firimu
