isicelo

Eyaziwa ngokuba yi-POLYVINYL CHLORIDE FILM, yenziwePVC intlakakunye nezinye izilungisi ngenkqubo yekhalenda okanye inkqubo yokubumba isivuthelo.Ubukhulu ngokubanzi yi-0.08~ 0.2mm, inkulu kune-0.25mm ebizwa ngokuba yi-PVC sheet.I-resin ye-PVC yongeza i-plasticizer, i-stabilizer, i-lubricant kunye nezinye i-AIDS ezisebenzayo, i-calendering film.

Olu hlobo lokugcinwa kobushushu befilimu, ukuhanjiswa kokukhanya kulungile, kuthambile kwaye kulula ukumila, kufanelekile kwi-greenhouse, i-greenhouse kunye nezinto ezincinci zokugquma zangaphandle.

Ukungalungi: umlinganiselo ophantsi wefilimu, ixabiso eliphezulu;Ukumelana nemozulu embi, ilukhuni kunye ne-brittle kwiqondo lokushisa eliphantsi, kulula ukuthambisa kunye nokukhululeka kwiqondo lokushisa eliphezulu;Emva kwemvula yezongezo, ifilimu yokucoca ifilimu, ichaphazela ukuhanjiswa kokukhanya;Ifilimu eshiyekileyo ayinakonakala kunye nonyango lokutsha.

Ifilimu yePVC inokwahlulwa ngokweendidi ezimbini, enye yiFilimu yePVC yePlastiki, eyaziwa ngokuba yiFilimu yePVC ethambileyo (iPlasticized PVC Film), enye ingeyiyo iPlasticized PVC Film, eyaziwa ngokuba yiPVC Film enzima (Unplasticized PVC Film) Phakathi kwabo, Iiakhawunti ze-PVC eziqinileyo malunga ne-2/3 yemarike, kunye nee-akhawunti ze-PVC eziguquguqukayo ze-1/3.

I-PVC ethambileyo isetyenziswa ngokubanzi emgangathweni, isilingi kunye nesikhumba, kodwa ngenxa yokuba i-PVC ethambileyo iqulethe isithambisi (oku ikwangumahluko phakathi kwe-PVC ethambileyo kunye ne-PVC enzima), kulula ukuba yi-brittle, akukho lula ukuyigcina, ngoko ukusetyenziswa kwayo kulinganiselwe. I-PVC ayinayo i-ejenti yokuthambisa, ngoko ke ukuguquguquka, ukubumba okulula, ukungabonakali, ukungcoliseka okungeyona ityhefu, ixesha lokulondoloza lide, ngoko uphuhliso kunye nokusetyenziswa kwexabiso elikhulu lefilimu ye-PVC ngundoqo wefilimu ye-vacuum blister, esetyenziselwa zonke iintlobo zepaneli yomgangatho wokupakisha, eyaziwa ngokuba yifilimu yokuhombisa Qhoboshela ifilimu, esetyenziswa kwizixhobo zokwakha ukupakisha amayeza, kunye namanye amashishini amaninzi Ishishini lezinto zokwakha libalwa njengelona candelo likhulu, i-60%, lilandelwa lishishini lokupakisha, kukho inani lezinye izicelo ezincinci zeshishini ngokwefilimu eyenza ukuhlelwa kwezinto eziluhlaza: ifilimu ye-polyethylene, ifilimu ye-polypropylene, ifilimu ye-PVC kunye nefilimu ye-polyester Ngokokuhlelwa kokusetyenziswa kwefilimu: ifilimu yezolimo (apha ngokubhekiselele kusetyenziso oluthile lwefilimu yezolimo, ingaba yahlulwe ibe yifilim ye-mulching kunye nefilimu ye-greenhouse);Ifilimu yokupakisha (ifilimu yokupakisha ngokweenjongo zabo ezithile, kwaye inokwahlulwa ibe yifilimu yokupakisha ukutya kunye nazo zonke iintlobo zeemveliso zoshishino kunye nefilimu yokupakisha, njl.njl.) kwaye isetyenziswa kwindawo ekhethekileyo ifilimu ephefumulayo ene-USES ekhethekileyo, ifilimu enyibilikayo yamanzi kwaye inefilimu yokupakisha. ukusebenza kwefilimu ebhityileyo ye-piezoelectric njalo njalo Ngokweendlela zokwenza ukuhlelwa kwefilimu: i-extrusion plasticizing Emva koko vuthela ukubunjwa kwefilimu ebhityileyo, ebizwa ngokuba yifilimu evuthelweyo;Emva plasticizing extrusion, kwaye ke imathiriyeli etyhidiweyo evela emlonyeni ukungunda flow ulwandiso lokubumba ifilimu, ebizwa ngokuba flow extension film;Ifilimu eyenziwe ngezinto zeplastiki ezigqitywe ngama-roller amaninzi kwi-calender ibizwa ngokuba yifilimu ye-calendered.
