Lintlha tsa Sehlahisoa

Li-tag tsa Sehlahisoa

Sehlopha sa lifilimi tsa PVC,
PVC bakeng sa filimi, PVC resin bakeng sa Flexible Vinyl Film, Resin ea PVC bakeng sa Filimi e Rigid Vinyl,

Filimi ea PVC ntle le polasetiki e bitsoa filimi e thata ea vinyl, athe PVC e entsoeng ka polasetiki e bitsoa filimi ea vinyl e bonolo.
1.Flexible Vinyl Film

Filimi e feto-fetohang ea vinyl e na le thepa e ntle ea tšitiso ea oli le mafura empa e khona ho kenella ka oksijene.E boetse e na le ho khomarela hantle, ho hlaka ho hoholo le ho hanyetsa ho phunya.Lintho tsena li etsa hore PVC e tenyetsehang e loketse ho paka lijo ho boloka nama le lihlahisoa tse ling tse senyehang li le foreshe (ha FDA e amohela).Leha ho le joalo, PVC e entsoeng ka polasetiki e na le ntlha e tlaase ea ho qhibiliha, ha e hanyetsane le lik'hemik'hale, 'me e na le matla a tlaase a ho feta ho feta vinyl e thata.

Filimi ea 2.Rigid Vinyl

Rigid vinyl, e tsejoang hape e le unplasticized polyvinyl chloride (uPVC), ke filimi e matla le e bobebe.Ke e 'ngoe ea lifilimi tse tšoarellang ka ho fetisisa tse theko e tlaase 'me e hanyetsa lik'hemik'hale tse ngata.Ka kakaretso, uPVC e ka sebelisoa mochesong o fihlang ho 60°C.E na le matla a holimo le modulus ho feta PVC e tenyetsehang, empa e na le matla a fokolang, 'me e tlas'a khatello ea maikutlo ho latela tikoloho.

PVC e na le mefokolo le litšitiso tse 'maloa;plasticizer e ka thatafatsa maemong a batang 'me ea nolofatsa tlas'a maemo a chesang, e leng se lebisang phetohong ea thepa mme e ka senya matla a tiiso.PVC e boetse e ntša hydrogen chloride e nyenyane moeeng 'me e hlahisa carbon deposit holim'a thepa ea ho tiisa ha e futhumala.Ka lebaka lena, moea o motle oa hlokahala ha ho tiisa PVC shrink-wrap.

LIKOPO
Filimi ea PVC e sebelisoa e le sekoahelo sa ho honyela le ho otlolla thepa ea indasteri le ea bareki le joalo ka sephutheloana sa pallet, leha ho le joalo, ka tekanyo e nyane ho feta lifilimi tsa polyolefin.Litšebeliso tse ling li kenyelletsa mekotla, li-liner, seleeve sa botlolo, tšehetso ea theipi e khomarelang, li-labels, mekotla ea mali le mekotla ea IV.Hangata e koahetsoe ke PVDC ha ho hlokahala thepa e ntlafetseng ea thibelo ea mongobo.

PVC e amohetsweng ke FDA ke kgetho e ntle ya ho paka nama e kgubedu e foreshe hobane ha e dumellehe, ho bolelang hore ho na le oksijene e lekaneng ho boloka dihlahiswa tsa nama di le foreshe le ho boloka mmala wa yona o mokgubedu o kganyang.Ha ponaletso e le ea bohlokoa, hangata PVC e sebelisoa.

Polyvinyl Chloride, e bitsoang PVC, ke e 'ngoe ea mefuta ea polasetiki e tsoetseng pele ea indasteri, tlhahiso ea hona joale ke ea bobeli feela ho polyethylene.Polyvinyl chloride e sebelisitsoe haholo indastering, temong le bophelong ba letsatsi le letsatsi.Polyvinyl chloride ke motsoako oa polymer o entsoeng ka vinyl chloride.Ke thermoplastic.Phofo e tšoeu kapa e bobebe e mosehla. E qhibiliha ka har'a li-ketone, esters, tetrahydrofuran le li-hydrocarbon tse chlorine.E babatsehang khanyetso ea lik'hemik'hale.Botsitso bo fokolang ba mocheso le ho hanyetsa khanya, ho feta 100 ℃ kapa ho pepeseha ha nako e telele ho letsatsi ho ile ha qala ho bola hydrogen chloride, tlhahiso ea polasetiki e hloka ho eketsa stabilizer.Insulation ea motlakase e ntle, e ke ke ea chesa.

Grade S-700 e sebelisoa haholo-holo ho hlahisa li-flakes tse bonaletsang, 'me e ka hatelloa ho selae se thata kapa se thata-thata kapa lakane bakeng sa sephutheloana, thepa ea fatše, filimi e thata bakeng sa lesela (bakeng sa pampiri ea lipompong kapa filimi ea ho paka sakerete), joalo-joalo. hape e fetisetsoe selae se thata kapa se thata, lakane, kapa bareng e sa bōpehileng hantle bakeng sa sephutheloana.Kapa e ka enteloa ho etsa manonyeletso, li-valve, likarolo tsa motlakase, lisebelisoa tsa likoloi le likepe.
