isicelo

Ifilimu ye-PVC ye-calendering iwuhlobo lwepulasitiki evaliwe ye-foam ehlanganiswe nge-polyvinyl chloride resin njengento eyisisekelo, enezela i-ejenti egwebuzelayo, isigxivizo nezinye izinto ezisizayo, ngemva kokuxova, ukugaya ibhola, ukubumba nokugwaza.Ngaphezu kwezakhiwo ezithambile neziqinile zemikhiqizo yobuchwepheshe, kunezinhlobo ezintathu zekhwalithi ethambile, ikhwalithi ephukile yezinkomo kanye nekhwalithi.

Ifilimu ye-PVC ye-calendering yenziwa inqubo ye-calendering, i-calendering ukushisa kwepulasitiki ye-PVC ngokusebenzisa i-pair noma ngaphezulu kwegebe lokujikeleza kwe-roller evundlile, ukuze impahla ngaphansi kwe-extrusion, isandiso, futhi ibe umkhiqizo omncane nobukhulu obuthile, ububanzi kanye inqubo ebusweni bushelelezi.Ifilimu ye-Polyvinyl chloride rolling idlala indima ebalulekile efilimini yepulasitiki.Ngaphezu kwalokho, isetshenziswa kabanzi ku-salting sheet, ukupakishwa kwezimboni, ukufakwa kukagesi, imikhiqizo yefilimu e-inflatable, ukukhangisa kwebhokisi elikhanyayo, ubunjiniyela obungangeni manzi, ukupakishwa kwezidingo zansuku zonke nokunye.

Isizathu esenza ifilimu ye-PVC yekhalenda isetshenziswe kabanzi ukuthi inezici ezilandelayo.

Amandla okuqina aphezulu

Amandla aqinile wefilimu yekhalenda ye-PVC afika ku-29MPa.Esikhathini esidlule iziphepho zesihlabathi enyakatho-ntshonalanga ye-China, ifilimu ye-PE nefilimu ye-EVA yonakalisiwe, kodwa ifilimu yekhalenda ye-PVC yayiphelele.

Ukusebenza kahle kwe-thermal insulation

Njengesembozo sezindawo zokugcina izithombo zezolimo, ingilazi inokusebenza okuhle kakhulu kokufakwa kwe-thermal, ilandelwa yifilimu ye-PVC calenning (enamandla okumunca infrared eqinile), bese kuba yifilimu ye-PE.Ngaphezu kwalokho, ebusuku PVC calendered ifilimu insulation ukusebenza kanye ingilazi akuhlukile, okuzuzisa kakhulu ukukhuthaza ukukhula izitshalo.

Ukucaca okuhle

Ifilimu ye-PVC yekhalenda ekubunjweni ngemuva kokukhishwa kwe-mirror roller, isiphetho esingaphezulu siphezulu kakhulu, isimo sokufiphala kwamanzi sincane, ngakho-ke ukukhanya kuphezulu, okuzuzisa kakhulu ku-photosynthesis yezitshalo.

Ubukhulu be-homogeneous

Ngenxa yokuthi umqulu wefilimu yekhalenda ye-PVC usesimweni sesigubhu, i-middle roll iyaphambana, i-roll engezansi ine-pre-strain, futhi ingaphezulu le-roll ligaywe kahle, ngakho ukunemba kogqinsi kuphezulu.

Ukusebenza okuhle kokuhlangana

Ngokwezidingo zokusetshenziswa, ifilimu ye-PVC ye-calendering ingaba yi-high-frequency welding, i-hot bonding ne-adhesive bonding izindlela, kulula ukuyisebenzisa.

Ngaphezu kwalokho, ngokusho kokusetshenziswa okuhlukile kwefilimu ye-PVC ye-calendering, kungahlangatshezwana nayo ngokushintsha ifomula yokukhiqiza kanye nezimo zenqubo.
