POLYVINYL CHLORIDE FILM, yenziwePVC intlakakunye nezinye izilungisi ngenkqubo yekhalenda okanye inkqubo yokubumba ukuvuthela.Ubukhulu ngokubanzi yi-0.08~0.2mm, inkulu kune-0.25mm ebizwa ngokuba yi-PVC sheet.I-Plasticizer, i-stabilizer, i-lubricant kunye nezinye izinto ezisebenzayo ze-AIDS zongezwa kwi-resin ye-PVC, kwaye ifilimu yenziwe nge-calendering.
Ifilim yePVC inokwahlulwa ngokweendidi ezimbini, enye yiFilimu yePVC eyenziwe ngePlastiki, ekwaziwa ngokuba yiFilimu yePVC ethambileyo, enye yiFilimu yePVC engafakwanga iplastiki, eyaziwa ngokuba yiFilimu yePVC enzima.
Phakathi kwazo, i-akhawunti ye-PVC enzima malunga ne-2/3 yemarike, kunye ne-akhawunti ye-PVC ethambileyo ye-1/3.I-PVC ethambileyo isetyenziselwa ngokubanzi umgangatho, 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 uluhlu lwayo lokusetyenziswa lulinganiselwe. .I-PVC enzima ayiqulathanga isithambisi, ngoko ke sinokuguquguquka okuhle, ukubumba okulula, akukho lula ukukrazula, okungeyona ityhefu kunye nokungangcolisi, ixesha elide lokugcinwa, ngoko inophuhliso olukhulu kunye nexabiso lesicelo.Undoqo wefilimu ye-PVC yifilimu ye-vacuum blister, esetyenziselwa ukupakishwa komphezulu wazo zonke iintlobo zeepaneli, ngoko ke ikwabizwa ngokuba yifilimu yokuhombisa, ifilimu encamathelayo, esetyenziswa kwizinto zokwakha, ukupakisha, amayeza kunye namanye amashishini amaninzi.Phakathi kwabo, ishishini lezinto zokwakha zenza inxalenye enkulu ye-60%, ilandelwa yimboni yokupakisha, kukho inani lezinye izicelo ezincinci zeshishini.
⑴ Ngokwezinto ezisetyenziselwa ukwenza ifilimu: ifilimu ye-polyethylene, ifilimu ye-polypropylene, ifilimu ye-polyvinyl chloride kunye nefilimu ye-polyester.
(2) Ukuhlelwa ngokusetyenziswa kwefilimu: ifilimu yezolimo (apha ngokubhekiselele kusetyenziso oluthile lwefilimu yezolimo, inokwahlulwa ibe yifilimu yeplastiki kunye nefilimu eluhlaza);Ifilimu yokupakisha (ifilimu yokupakisha ngokusetyenziswa kwayo ethile, kwaye inokwahlulwa ibe yifilimu yokupakisha ukutya kunye nemveliso eyahlukeneyo yemveliso yokupakisha ifilimu, njl.njl.) kunye nendawo ekhethekileyo, ngokusetyenziswa okukhethekileyo kwefilimu ephefumlayo, ifilimu enyibilikayo yamanzi kunye neepropathi zepiezoelectric zefilimu. .
(3) Ngokwendlela yokubumba ifilimu yokuhlelwa: iplastiki ye-extrusion, kwaye emva koko ivuthele ifilimu yokubumba, ebizwa ngokuba yifilimu yokubumba ifilimu;Emva kweplastiki ye-extrusion, kwaye ke into etyhidiweyo iphuma emlonyeni wokubumba ifilimu eyenza ifilimu, ebizwa ngokuba yifilimu ehambayo;Kumatshini we-calendering yimiqulu emininzi ephothiweyo yeplastiki eyenziwe ngefilimu, ebizwa ngokuba yifilimu ye-calendering.
Ukusetyenziswa kwefilimu yePVC
Izinto zokuhombisa ze-PVC: Ikwanazo neempawu zokuchasana nokuguga kunye nokuthontsiza, ukuhanjiswa kokukhanya okulungileyo kunye nokugcinwa kobushushu, ngaphandle kokuchasana nokuthontsiza kangangeenyanga ezi-4 ukuya kwezi-6 kunye nobomi benkonzo obukhuselekileyo beenyanga ezili-12 ukuya kwezili-18.Isetyenziswa ngokubanzi njengeyona nto isebenzayo kwaye igcina amandla egqumayo kwi-solar greenhouse.
I-PVC inokwenza ifilimu yeplastiki, ukongeza inani elithile lezinto eziphathekayo kunokuvelisa imibala eyahlukeneyo yefilimu echithiweyo.
I-PVC FOIL: iplastiki, isinyithi, ifilimu ecacileyo, ukupakishwa kwephepha, ukupakishwa kweplastiki, ukupakishwa kweenkuni, ukupakishwa kwesinyithi, njl.
