Polyvinyl chloride firimu inogadzirwa nepolyvinyl chloride resin uye mamwe ma modifiers kuburikidza necalendering process kana blow molding process. Ukobvu huzhinji 0.08 ~ 0.2mm, uye chero chinhu chikuru kupfuura 0.25mm chinonzi PVC sheet. Zvishandiso zvekugadzirisa zvinoshandiswa senge plasticizers, stabilizers, uye lubricant zvinowedzerwa kuPVC resin uye yakakungurutswa kuita firimu.
PVC Film Classification
Mafirimu ePolyvinyl chloride (PVC Firimu) anogona kukamurwa kuita zvikamu zviviri, imwe ipurasitiki yePVC firimu, uye imwe yacho isina purasitiki yePVC firimu.
Pakati pazvo, yakaoma PVC accounts inosvika 2/3 yemusika, uye yakapfava PVC account ye1/3. Soft PVC inowanzo shandiswa pauriri, sirin'i uye pamusoro pematehwe. Zvisinei, nokuti PVC yakapfava ine zvinyoro-nyoro (uyu ndiwowo mutsauko pakati pePVC yakapfava uye yakaoma PVC), inova nyore kuita brittle uye yakaoma kuchengetedza, saka huwandu hwayo hwekushandisa hushoma. Hard PVC haina zvinyoro-nyoro, saka ine yakanaka kuchinjika, iri nyore kuumba, kwete brittle, isiri-chepfu uye isingasvibise, uye ine nguva yakareba yekuchengetedza, saka ine budiriro huru uye kukosha kwekushandisa. Iyo yakakosha yePVC firimu ivacuum yepurasitiki-inotora firimu, iyo inoshandiswa kurongedza pamusoro pemhando dzakasiyana dzemapaneru. Nokudaro, inonziwo firimu rekushongedza uye firimu rekunamatira. Inoshandiswa mumaindasitiri mazhinji akadai sezvivakwa zvekuvaka, kurongedza, mishonga, nezvimwe. Pakati pavo, iyo indasitiri yezvivakwa inoverengera chikamu chikuru, ichiteverwa neindasitiri yekurongedza, uye mamwe akati wandei madiki maindasitiri ekushandisa.
⑴ Kurongeka zvinoenderana nemidziyo inoshandiswa kugadzira firimu: polyethylene firimu, polypropylene firimu, polyvinyl chloride firimu uye polyester firimu, nezvimwe.
⑵ Kurongeka nekushandiswa kwemafirimu: Kune mafirimu ezvekurima (mafirimu ezvekurima anogona kupatsanurwa kuita mulch mafirimu uye magreenhouse mafirimu zvinoenderana nemashandisirwo awo chaiwo); kurongedza mafirimu (mafirimu ekurongedza anogona kukamurwa kuita mafirimu ekurongedza chikafu uye akasiyana zvigadzirwa zvemaindasitiri zvinoenderana nemashandisirwo azvo chaiwo). firimu rekurongedza, nezvimwewo) uye mafirimu anofema enzvimbo dzakakosha uye zvinangwa zvakakosha, mafirimu anonyungudika nemvura uye mafirimu ane piezoelectric properties, nezvimwe.
⑶ Yakarongedzerwa maererano nenzira yekugadzira firimu: kune mafirimu akaiswa epurasitiki neextrusion uye obva afuridza akaumbwa, anodaidzwa kupepetwa mafirimu; mafirimu akaiswa plasticized ne extrusion uye obva akandwa nezvinhu zvakanyungudutswa kubva mumuromo mould anonzi akakanda mafirimu. ; Iyo firimu yakagadzirwa nepurasitiki yakagadziriswa zvinhu zvakatenderedzwa nema roller akati wandei pane calender inonzi calendered film.
PVC Film Kushandisa
Kazhinji, huwandu hukuru hwematepi hunoshandiswa mumunda wemagetsi. Zvichienderana nehunhu hwayo, inogona zvakare kushandiswa tepi yekudzivirira, tepi yekutakura, tepi yekuzivikanwa, zvimiti zvekushambadzira, tepi yepipeline, nezvimwe. Inoshandiswawo zvakanyanya muhupenyu hwezuva nezuva, seshangu, matoyi, raincoats, tablecloths, maamburera, zvekurima. mafirimu, nezvimwewo.
Yakajairika PVC greenhouse firimu: Hapana anti-kuchembera additives inowedzerwa panguva yekugadzira firimu. Hupenyu hwesevhisi ndeye 4 kusvika kumwedzi mitanhatu. Inogona kubereka mwaka mumwe wezvirimwa. Parizvino iri kumiswa.
PVC anti-kuchembera firimu: Anti-aging additives inowedzerwa kune mbishi zvinhu uye yakakungurutswa kuita firimu. Iine nguva yekushandisa inoshanda ye8 kusvika kumwedzi gumi uye ine yakanaka transmittance yechiedza, kuchengetedza kupisa uye kuramba mamiriro ekunze.
PVC yekushongedza zvinhu: Iyo ine anti-kuchembera uye inodonha zvivakwa, yakanaka mwenje transmittance uye kupisa kwemafuta. Haikwanise kuramba ichidonha kwemwedzi mina kusvika kumitanhatu uye ine hupenyu hwesevhisi hwakachengeteka hwemwedzi gumi nemiviri kusvika gumi nemisere. Inoshandiswa zvakanyanya uye parizvino ndiyo inonyanya kushanda. Magetsi anochengetedza solar greenhouses anotanga akafukidzwa nezvinhu.
PVC inodzivirira mamiriro ekunze isingadonhedze guruva-inoratidza firimu: Pamusoro pekusagadzikana kwemamiriro ekunze uye kudonha-kudonha, pamusoro pefirimu yakarapwa kuderedza kunaya kweplasticizer uye kushomeka kweguruva, iyo inovandudza kufambiswa kwechiedza uye inobatsira zvakanyanya. kukurima kwechando uye muchirimo mu solar greenhouses.
PVC inogona zvakare kushandiswa semulch firimu, uye imwe huwandu hwemavara masterbatch inogona kuwedzerwa kuburitsa akadurura mafirimu emavara akasiyana.
PVC foil: mapurasitiki, simbi, läpinäkyvä firimu, asiri-bepa kurongedza, epurasitiki kurongedza, mapuranga kurongedza, simbi kurongedza, etc.
