Ibakala lefilimu yePVC
Ibakala lefilimu yePVC,
I-PVC yefilimu, PVC resin for Flexible Vinyl Film, PVC resin for Rigid Vinyl Film,
Ifilimu ye-PVC ngaphandle kwe-plasticizer ibizwa ngokuba yifilimu ye-vinyl eqinile, ngelixa i-PVC eyenziwe ngeplastiki ibizwa ngokuba yifilimu yevinyl eguquguqukayo.
1.Flexible Vinyl Film
Ifilimu yeVinyl eguquguqukayo ineempawu ezintle zokuthintelwa kweoyile kunye negrisi kodwa iyakwazi ukungena ioksijini.Ikwanakho nokuncamathela okulungileyo, ukucaca okugqwesileyo kunye nokumelana nokugqabhuka.Ezi zakhiwo zenza i-PVC eguquguqukayo ilungele ukupakishwa kokutya ukugcina inyama kunye nezinye iimveliso ezitshabalalayo zintsha (xa i-FDA ivunyiwe).Nangona kunjalo, iPVC eyenziwe ngePlasitiki inendawo esezantsi yokunyibilika, ayixhathisi kangako kwiikhemikhali, kwaye inamandla asezantsi okuqina kunevinyl eqinile.
2.Ifilimu yeVinyl eRigid
I-Vinyl eqinile, ekwaziwa njenge-polyvinyl chloride engafakwanga (uPVC), yifilimu eyomeleleyo nekhaphukhaphu.Yenye yeefilimu ezihlala ixesha elide ezinexabiso eliphantsi kwaye ixhathisa kwiikhemikhali ezininzi.Ngokubanzi, iPVC ingasetyenziswa kumaqondo obushushu ukuya kuma 60°C.Inamandla aphezulu okuqina kunye nemodyuli kunePVC eguquguqukayo, kodwa inefuthe eliphantsi lokuqina, kwaye ixhomekeke kuxinzelelo lokuqhekeka ngokuxhomekeke kwimekobume.
I-PVC inezithintelo ezininzi kunye neengxaki;i-plasticizer ingakwazi ukuqina kwiimeko ezibandayo kwaye ithobe phantsi kweemeko ezishushu, ezikhokelela ekutshintsheni iipropati kwaye zingakwazi ukuphazamisa amandla esitywina.I-PVC ikwakhupha izixa ezincinci ze-hydrogen chloride emoyeni kwaye ivelise idiphozithi yekhabhoni kwisixhobo sokutywina xa ishushu.Ngesi sizathu, umoya olungileyo uyafuneka xa utywina iPVC shwabanisa-isonga.
IZICELO
Ifilimu yePVC isetyenziswa njengokuncipha kunye nokusonga kwempahla yeshishini kunye nabathengi nanjengokusonga ipallet, nangona kunjalo, kumlinganiselo omncinci kuneefilimu zepololefin.Olunye usetyenziso lubandakanya iingxowa, ii-liners, i-sleeving yebhotile, i-adhesive tape backing, iilebhile, iingxowa zegazi kunye ne-IV.Ihlala igqunywe ngePVDC xa kufuneka iipropathi eziphuculweyo zokuthintela ukufuma.
I-FDA evunyiweyo ye-PVC lukhetho olulungileyo lokupakisha inyama ebomvu entsha kuba i-semi-permeable, oku kuthetha ukuba, i-oksijini eyanele ngokwaneleyo ukugcina iimveliso zenyama zintsha kunye nokugcina umbala wayo obomvu oqaqambileyo.Xa ukucaca kubalulekile, iPVC isoloko isetyenziswa.
I-Polyvinyl Chloride, ebizwa ngokuba yi-PVC, yenye yeendidi zeplastiki eziphuculweyo, imveliso yangoku yesibini kuphela kwi-polyethylene.I-Polyvinyl chloride isetyenziswe ngokubanzi kwishishini, ezolimo kunye nobomi bemihla ngemihla.I-Polyvinyl chloride yikhompawundi yepolymer eyenziwe nge-vinyl chloride.Yi-thermoplastic.Umgubo omhlophe okanye okhanyayo ophuzi.Inyibilika kwiiketoni, ii-esters, i-tetrahydrofurans kunye ne-chlorinated hydrocarbons.Ukuchasana kweekhemikhali okugqwesileyo.Uzinzo olubi lwe-thermal kunye nokumelana nokukhanya, ngaphezu kwe-100 ℃ okanye ukukhanya kwelanga ixesha elide kwaqala ukubola i-hydrogen chloride, ukuveliswa kweplastiki kufuna ukongeza i-stabilizer.Ukufakelwa kombane kulungile, akusayi kutshisa.
IBanga le-S-700 lisetyenziswa ikakhulu ukuvelisa iiflakes ezicacileyo, kwaye zinokucinezelwa kwisilayi esiqinileyo okanye esingaqini-qini okanye ishidi ukuze iphakheji, imathiriyeli yomgangatho, ifilimu eqinileyo yokufakwa kwelineni (yephepha lokusonga iilekese okanye ifilimu yokupakisha icuba), njl. kwakhona ikhutshelwe kwisilayi esiqinileyo okanye esilukhuni, ishiti, okanye ibha enemilo engaqhelekanga yephakheji.Okanye inokutofwa ukwenza amajoyinti, iivalve, iinxalenye zombane, izixhobo zemoto kunye neenqanawa.
