imikhiqizo

Ibanga lefilimu le-PVC,
I-PVC yefilimu, PVC resin for Flexible Vinyl Film, I-PVC resin ye-Rigid Vinyl Film,

Ifilimu ye-PVC ngaphandle kwe-plasticizer ibizwa ngokuthi ifilimu ye-vinyl eqinile, kanti i-PVC eyenziwe ngepulasitiki ibizwa ngokuthi ifilimu ye-vinyl eguquguqukayo.
1.Flexible Vinyl Film

Ifilimu ye-vinyl eguquguqukayo inezindawo ezinhle zokuvimbela uwoyela namafutha kodwa iyakwazi ukungena komoyampilo.Futhi inokunamathela okuhle, ukucaca okuhle kakhulu kanye nokumelana nokubhoboza.Lezi zakhiwo zenza i-PVC eguquguqukayo ifanele ukupakishwa kokudla ukuze kugcinwe inyama nokunye okubolayo kusha (uma i-FDA ivuma).Kodwa-ke, i-PVC eyenziwe ngepulasitiki inendawo encibilikayo ephansi, ayizweli kancane kumakhemikhali, futhi inamandla aphansi okuqina kune-vinyl eqinile.

2.Ifilimu yeVinyl Eqinile

I-vinyl eqinile, eyaziwa nangokuthi i-polyvinyl chloride engafakwanga epulasitiki (i-uPVC), iyifilimu eqinile futhi engasindi.Ingenye yamafilimu ahlala isikhathi eside anezindleko eziphansi futhi amelana namakhemikhali amaningi.Ngokuvamile, i-UPVC ingasetshenziswa emazingeni okushisa afinyelela ku-60°C.Inamandla aphezulu okuqinile kanye ne-modulus kune-PVC eguquguqukayo, kodwa inomthelela omncane wokuqina, futhi ingaphansi kokuqhekeka kwengcindezi kuye ngendawo ezungezile.

I-PVC inemikhawulo eminingana kanye nezithiyo;i-plasticizer ingakwazi ukuqina ezimweni ezibandayo futhi ithambe ngaphansi kwezimo ezishisayo, okuholela ekushintsheni kwezakhiwo futhi ingaphazamisa amandla ophawu.I-PVC iphinde ikhiphe amanani amancane e-hydrogen chloride emoyeni futhi ikhiqize idiphozithi ye-carbon emshinini wokuvala uma ishisiwe.Ngenxa yalesi sizathu, umoya omuhle uyadingeka lapho uvala i-PVC shrink-wrap.

IZICELO
Ifilimu ye-PVC isetshenziswa njengokugoqa nokwelula kwezimpahla zezimboni nezabathengi nanjengokugoqa i-pallet, nokho, ngesilinganiso esincane kakhulu kunamafilimu e-polyolefin.Okunye ukusetshenziswa kuhlanganisa izikhwama, omalayini, imikhono yamabhodlela, i-adhesive tape backing, amalebula, izikhwama zegazi kanye nezikhwama ze-IV.Ivamise ukugqunywa nge-PVDC lapho izakhiwo zokuvimbela umswakama ezithuthukisiwe zidingeka.

I-PVC egunyazwe yi-FDA iyisinqumo esihle sokupakisha inyama ebomvu entsha ngoba ingeneka kancane, okusho ukuthi kungena umoya-mpilo owanele ukugcina imikhiqizo yenyama iyintsha kanye nokugcina umbala wayo obomvu ogqamile.Uma ukukhanya kubalulekile, i-PVC ivame ukusetshenziswa.

I-Polyvinyl Chloride, ebizwa ngokuthi i-PVC, ingenye yezinhlobo zepulasitiki ezithuthukisiwe, okukhiphayo okwamanje kungokwesibili ngemuva kwe-polyethylene.I-Polyvinyl chloride isetshenziswe kabanzi embonini, ezolimo kanye nempilo yansuku zonke.I-Polyvinyl chloride iyinhlanganisela ye-polymer eyenziwe nge-vinyl chloride.I-thermoplastic.Impushana emhlophe noma ekhanyayo ephuzi.Incibilika kuma-ketone, esters, tetrahydrofuran kanye nama-hydrocarbon ane-chlorine.Ukumelana kwamakhemikhali okuhle kakhulu.Ukungaqini kahle kokushisa nokumelana nokukhanya, ukukhanya kwelanga okungaphezu kuka-100 ℃ noma isikhathi eside kwaqala ukubola i-hydrogen chloride, ukukhiqizwa kwepulasitiki kudinga ukwengeza isizinzi.Ukufakwa kukagesi kuhle, ngeke kushise.

IBanga S-700 lisetshenziselwa ikakhulukazi ukukhiqiza ama-flakes akhanyayo, futhi lingacindezelwa ocekeni oluqinile noma oluqinile noma ishidi ukuze lifakwe iphakheji, impahla yaphansi, ifilimu eqinile yokugqoka (iphepha likaswidi lokugoqa noma ifilimu yokupakisha ugwayi), njll. futhi idluliselwe kusicezu esiqinile noma esiqinile, ishidi, noma ibha emise ngendlela engavamile yephakheji.Noma ingajovwa ukwenza amalunga, ama-valve, izingxenye zikagesi, izesekeli ezizenzakalelayo kanye nemikhumbi.
