Resin ea PVC e sebelisetsoang ho hlahisa WPC, Lisebelisoa tse tala bakeng sa tlhahiso ea WPC.,
WPC ke mofuta o mocha oa thepa e baballang tikoloho, e kopantsoeng le lehong le polasetiki, e nang le sebopeho sa lehong le ho tšoarella ha polasetiki.Ts'ebetso ea tlhahiso ea WPC haholo-holo e kenyelletsa ho lokisoa ha thepa e tala, ho kopanya, extrusion, ho pholisa, ho itšeha le ho paka.
Tokiso ea thepa e tala ke mohato oa pele oa tlhahiso ea WPC.Lisebelisoa tse tala tsa WPC haholo-holo li kenyelletsa phofo ea lehong, polasetiki, li-additives joalo-joalo.Har'a tsona, phofo ea lehong e entsoe ka lehong ka mor'a ho senya, ho hlahloba le mekhoa e meng, 'me polasetiki e entsoe ka polyethylene, polypropylene le lisebelisoa tse ling tsa polasetiki.Li-additives li kenyelletsa li-preservative, li-antioxidants, li-pigments, joalo-joalo, tse sebelisetsoang ho ntlafatsa ts'ebetso le botle ba WPC.
Ho kopanya ke mokhoa oa ho kopanya phofo ea lehong, polasetiki le li-additives ka tekanyo e itseng.Sepheo sa ho kopanya ke ho etsa hore lisebelisoa tse sa tšoaneng tse tala li kopane ka ho feletseng ho etsa motsoako o ts'oanang, o itokiselitse mokhoa o latelang oa extrusion.
Joale, extrusion ke mokhoa oa ho pepeta lisebelisoa tse tala tse tsoakiloeng ka extruder.Extruder e futhumatsa thepa e tala e tsoakiloeng ho mocheso o itseng ho etsa hore e be bonolo, ebe e e ntša ka hlobo.Boto ea lehong-polasetiki e extruded e na le sebōpeho le boholo bo itseng, empa hape e hloka ho pholile le ho khaola.
Joale, ho pholisa ke mokhoa oa ho beha WPC e extruded holim'a sethala sa ho pholisa bakeng sa ho pholisa ka tlhaho.Sepheo sa ho pholisa ke ho pholisa WPC ka potlako, ho etsa hore sebopeho sa eona le boholo ba eona li tsitsitse, le ho qoba mathata a kang deformation le cracking.
Ho seha le ho paka ke mokhoa oa ho seha le ho paka WPC e pholileng.Ho khaola ke ho khaola boto ea lehong-polasetiki ho latela boholo bo itseng, e le hore e finyelle litlhoko tsa bareki.Packaging ke ho seha boto ea polasetiki ea lehong bakeng sa ho paka, molemong oa ho tsamaisa lipalangoang le thekiso.
Ts'ebetso ea tlhahiso ea WPC e kenyelletsa ho lokisa thepa e tala, ho kopanya, extrusion, pholiso, ho itšeha le ho paka.Lihokelo tsena li sebelisana 'moho ho phethela tšebetso ea tlhahiso ea WPC, ho fa batho thepa e ncha e se nang botsoalle, e ntle le e tšoarellang nako e telele.
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.
Sehlopha sa S-700e sebelisoa haholo ho hlahisa lipampiri tse bonaletsang, 'me e ka phuthoa ka har'a maqephe a thata-thata bakeng sa sephutheloana, thepa ea fatše, filimi e thata bakeng sa lesela (bakeng sa pampiri e phuthelang lipompong kapa filimi ea ho paka sakerete), joalo-joalo E ka boela ea fetisetsoa ho thata kapa filimi, lakane, kapa sebōpeho se sa tsitsang bakeng sa sephutheloana.Kapa e ka enteloa ho etsa manonyeletso, li-valve, likarolo tsa motlakase, lisebelisoa tsa likoloi le likepe.
