I-resin ye-PVC yefilimu
I-resin ye-PVC yefilimu,
I-resin ye-PVC yefilimu eqinile, pvc resin yefilimu yePVC ethambileyo,
Ukuveliswa kwefilimu yePVC
Kukho ikakhulu iindlela ezimbini zokuvelisa ifilimu ye-pvc: i-extrusion calendering kunye ne-casting.I-Calendering ye-Extrusion yeyona ndlela.
Ifilimu ye-PVC inokwahlulwa ibe ngamaqela amabini aphambili: ithambile kwaye i-semi-rigid.Imfuno yentengiso yefilimu yePVC engqongqo ifikelela phantse kwisibini esithathwini.
Iphepha elithambileyo lePVC lisetyenziswa ngokubanzi kumalaphu etafile, iimethi ezingatyibilikiyo, kunye neengxowa.Ngenxa yokuba ishidi elithambileyo le-PVC okanye ifilimu iqulethe izinto ezithambileyo, kulula ukuba brittle kwaye kunzima ukuzigcina.Oku kunciphisa umda wosetyenziso.
I-PVC eqinile ayinazo izinto zokuthambisa.Iyabhetyebhetye, kulula ukuyibumba, akukho lula ukuba yibrittle, ayinayo ityhefu kwaye ayinangcoliseko.Inexesha elide lokugcina, ukumelana nobushushu obuphezulu, akulula ukunyibilika.Iyaprintwa, kwaye inesiphumo esihle seinki.Inexabiso elikhulu kunye nezicelo ezinkulu.Isakhiwo kunye ne-electronics zisebenzisa i-60% ye-PVC ifilimu yeplastiki kunye namaphepha.Imizi-mveliso emininzi yokupakisha ikwasebenzisa izinto ezininzi zePVC.Kukwakho nezicelo ezimbalwa, ezinje ngebhokisi yokubhala, ukusika i-laser, kunye neebhodi zokwahlula, njalo njalo.
