Ifilimu ye-Polyvinyl chloride yenziwe nge-polyvinyl chloride resin nezinye izilungisi ngenqubo ye-calendering noma inqubo yokubumba igalelo. Ubukhulu obujwayelekile bungu-0.08~0.2mm, futhi noma yini enkulu kuno-0.25mm ibizwa ngeshidi le-PVC. Izinsiza zokucubungula ezisebenzayo ezifana namaplasitiki, iziqinisi, nezinto zokugcoba zengezwa kunhlaka ye-PVC futhi zigoqwe zibe ifilimu.
I-PVC Film Classification
Amafilimu e-Polyvinyl chloride (Ifilimu ye-PVC) angahlukaniswa cishe abe izigaba ezimbili, eyodwa iyifilimu ye-PVC eyenziwe ngepulasitiki, kanti enye ifilimu ye-PVC engafakwanga ipulasitiki.
Phakathi kwazo, i-PVC eqinile ibalelwa ku-2/3 wemakethe, kanye nama-akhawunti athambile e-PVC angu-1/3. I-PVC ethambile ngokuvamile isetshenziselwa phansi, uphahla kanye nobuso besikhumba. Kodwa-ke, ngenxa yokuthi i-PVC ethambile iqukethe izinto ezithambile (lokhu futhi umehluko phakathi kwe-PVC ethambile ne-PVC eqinile), iba kalula futhi kube nzima ukuyilondoloza, ngakho ububanzi bayo bokusetshenziswa bulinganiselwe. I-PVC eqinile ayinazo izinto ezithambisayo, ngakho-ke inokuguquguquka okuhle, kulula ukubumba, ayi-brittle, ayinabuthi futhi ayingcolisi, futhi inesikhathi eside sokugcina, ngakho-ke inokuthuthukiswa okukhulu kanye nenani lesicelo. Ingqikithi yefilimu ye-PVC iyifilimu emunca ipulasitiki evacuum, esetshenziselwa ukupakishwa okungaphezulu kwezinhlobo ezahlukahlukene zamaphaneli. Ngakho-ke, kubizwa nangokuthi ifilimu yokuhlobisa nefilimu yokunamathisela. Isetshenziswa ezimbonini eziningi ezifana nezinto zokwakha, ukupakisha, imithi, njll. Phakathi kwazo, imboni yezinto zokwakha ibamba ingxenye enkulu, ilandelwa yimboni yokupakisha, kanye nezinye izimboni ezimbalwa zokufaka izicelo.
⑴ Ukuhlelwa ngokuya ngezinto zokusetshenziswa ezisetshenziselwa ukwenza ifilimu: ifilimu ye-polyethylene, ifilimu ye-polypropylene, ifilimu ye-polyvinyl chloride nefilimu ye-polyester, njll.
⑵ Ukuhlelwa ngokusetshenziswa kwefilimu: Kunamafilimu ezolimo (amafilimu ezolimo angahlukaniswa abe amafilimu e-mulch namafilimu abamba ukushisa ngokuya ngokusetshenziswa kwawo okuthile); amafilimu okupakisha (amafilimu okupakisha angahlukaniswa abe amafilimu okufaka ukudla kanye nemikhiqizo ehlukahlukene yezimboni ngokuya ngokusetshenziswa kwawo okuthile). ifilimu yokupakisha, njll.) namafilimu aphefumulayo ezindawo ezikhethekile nezinjongo ezikhethekile, amafilimu namafilimu ancibilika emanzini anezakhiwo ze-piezoelectric, njll.
⑶ Ahlukaniswa ngokwendlela yokwenza ifilimu: kukhona amafilimu enziwe ipulasitiki nge-extrusion abese ebunjwa ngokufutheka, abizwa ngokuthi amafilimu ashaywayo; amafilimu enziwe ipulasitiki nge-extrusion abese ejikijelwa ngezinto ezincibilikisiwe ezivela emlonyeni wesikhunta abizwa ngokuthi ama-cast film. ; Ifilimu eyenziwe ngezinto zokusetshenziswa zepulasitiki ezigoqwe ama-roller amaningana ku-calender ibizwa ngokuthi ifilimu ye-calendered.
Ukusetshenziswa kwefilimu ye-PVC
Ngokuvamile, inani elikhulu kakhulu le-tape lisetshenziswa emkhakheni kagesi. Kuye ngezici zayo, ingasetshenziselwa futhi i-tape yokuzivikela, i-tape yemithwalo, i-identification tape, izitika zokukhangisa, i-pipeline tape, njll. Ibuye isetshenziswe kabanzi ekuphileni kwansuku zonke, njengezicathulo, amathoyizi, ama-raincoat, izindwangu zetafula, izambulela, ezolimo. amafilimu, njll.
Ifilimu ye-PVC ye-greenhouse evamile: Azikho izithasiselo zokulwa nokuguga ezingeziwe ngesikhathi senqubo yokwenza ifilimu. Impilo yesevisi yizinyanga ezi-4 kuya kweziyisi-6. Ingakhiqiza isizini eyodwa yezitshalo. Njengamanje kuyaqedwa.
Ifilimu ye-PVC elwa nokuguga: Izithasiselo ezilwa nokuguga zengezwa ezintweni ezingavuthiwe futhi zigoqwe zibe ifilimu. Inesikhathi sokusebenzisa esisebenzayo sezinyanga eziyisi-8 kuya kweziyi-10 futhi inokudlulisa kahle ukukhanya, ukugcinwa kokushisa nokumelana nesimo sezulu.
Impahla yokuhlobisa ye-PVC: Inezici zokulwa nokuguga nokuconsa, ukukhanya okuhle kokukhanya kanye nokufakwa kwe-thermal. Ayikwazi ukugcina ingaconsi izinyanga ezi-4 kuya kweziyisi-6 futhi inempilo yesevisi ephephile yezinyanga eziyi-12 kuya kweziyi-18. Isetshenziswa kabanzi futhi njengamanje iyona esebenza kahle kakhulu. Izindlu zokugcina izithombo zelanga ezonga amandla kuqala zimbozwe ngezinto zokwakha.
Ifilimu ye-PVC engamelani nesimo sezulu engaconsi uthuli: Ngaphezu kokumelana nesimo sezulu kanye ne-drip-proof, indawo engaphezulu yefilimu ilashwe ukuze kuncishiswe imvula ye-plasticizer kanye nokumuncwa okuncane kothuli, okuthuthukisa ukudluliswa kokukhanya futhi kunenzuzo enkulu. ukulima ebusika nasentwasahlobo ezindaweni zokugcina izithombo zelanga.
I-PVC ingasetshenziswa futhi njengefilimu ye-mulch, futhi inani elithile le-masterbatch yombala lingangezwa ukukhiqiza amafilimu achithekile emibala ehlukahlukene.
Ucwecwe lwe-PVC: ipulasitiki, insimbi, ifilimu esobala, ukupakishwa okungelona iphepha, ukupakishwa kwepulasitiki, ukupakisha ngokhuni, ukupakishwa kwensimbi, njll.
