Izendlalelo ezintathu ze-PVC  Plastic Material

Isendlalelo esiphezulu se-PVC yi-lacquer, isakhi esiyinhloko esiphakathi yi-polyvinyl chloride, futhi ungqimba olungaphansi luyi-adhesive yokuhlanganisa emuva.

Ukusetshenziswa kwe-PVC Global

Izinto ze-PVC ziyinto ethandwa kakhulu, ethandwayo, esetshenziswa kabanzi kokwenziwa emhlabeni namuhla. Ukusetshenziswa kwalo komhlaba wonke kungokwesibili phakathi kwazo zonke izinto zokwenziwa. Ngokusho kwezibalo, ngo-1995 kuphela, ukukhiqizwa kwePVC eYurophu kwakungamathani ayizigidi ezi-5, kanti ukusetshenziswa kwawo kwakungamathani ayizigidi ezingama-5.3. EJalimane, ukukhiqizwa kwe-PVC kanye nokusetshenziswa kwamathani ayizigidi eziyi-1,4. I-PVC iyakhiqizwa futhi yasetshenziswa emhlabeni wonke ngezinga lokukhula le-4%. Ukukhula kwe-PVC eSoutheast Asia kuyaphawuleka ikakhulukazi, ngenxa yezidingo eziphuthumayo zokwakhiwa kwengqalasizinda emazweni aseNingizimu mpumalanga ye-Asia ase-Asia. Phakathi kwezinto zokwakha ezingakhiqiza amafilimu aphezulu aphezulu, i-PVC yizinto ezifanele kakhulu.

Izinhlobo ezahlukahlukene ze-PVC Plastic Material

I-PVC ingahlukaniswa ngefilimu le-PVC elithambile neshidi le-PVC eliqinile. Phakathi kwazo, ama-akhawunti aqinile we-PVC amaphepha acishe abe ngu-2/3 wemakethe, nama-akhawunti we-PVC athambile we-1/3. Ifilimu le-SOFT PVC livame ukusetshenziswa ebusweni bezitezi, ophahleni, nesikhumba. Kepha ngoba i-PVC ethambile iqukethe amathanga, kulula ukuba yi-brittle futhi kunzima ukuyigcina, ngakho-ke ubukhulu bawo bunqunyelwe. Lokhu futhi umehluko phakathi kwefilimu le-PVC elithambile neshidi le-PVC eliqinile. Ishidi le-PVC eliqinile alinawo ama-loofters, ngakho-ke linokuguquguquka okuhle, okulula ukuwathola, alikho lula ukuba yi-brittle, okungelona ubuthi kanye nokungcola, futhi linesikhathi eside sokugcina. Ngenxa yezinzuzo zayo ezisobala, inenani elikhulu kakhulu nenani lesicelo.
