Polyvinyl chloride (PVC) Liaparo tsa Powder - Ntlafatsa, Kopo, Phepelo

Pampiri ena e bua ka nts'etsopele ea polyvinyl chloride (PVC) ho roala phofo lapeng le linaheng tse ling, ho hlahisa mokhoa oa motheo, theknoloji ea ho lokisetsa le index ea tshebetso ea PVC phofshoana ea phofshoana, 'me e etsa kenyelletso e hlokahalang ea ts'ebeliso ea eona ho thibela ho bola le ho khabisa liphaephe tsa tšepe.

Tlhaloso

Ho roala ka phofo ke mofuta oa phofo e tiileng ea 100%. E fapane le ho roala ka kakaretso ho thehiloeng ho solvent le ho roala ha metsi, eseng ho qhibiliha kapa metsi e le mokhoa oa ho qhalakanngoa, empa ka thuso ea moea e le mokhoa oa ho qhalakanngoa. Nakong e fetileng decade, mebuso ea lefats'e ho hlahisa lifeme tsa likoahelo le likhoebo tse bakoang ke tšilafalo ea tikoloho e ntseng e eketseha tlhokomelo, e matlafalitse lithibelo tsa tšebeliso ea solvents. Qetellong ea lilemo tse mashome a robeli ka Europe le United States ha ho etsoa litlolo, tlhahiso, ts'ebeliso ea kaho e thibetsoe ka thata ts'ebeliso ea lihlapolli le mesi, likarolo tse ling tsa United States le tsona ka mokhoa oa melao li phatlalalitse molao oa thibelo ea tšebeliso ea solvent, lipehelo tsa ba bangata joalo ka 66 lihlooho, le Europe le United States li hlahisitse sepheo sa "E tse tharo":

(1) Phetoho ea Ikholoji
(2) Ho Boloka Matla
(3) Molemo oa Moruo

Tabeng ena, liphahlo tsa phofo li bile le tsoelo-pele e potlakileng ka lebaka la tlhaho ea tsona e se nang tšilafalo, tšebeliso e phahameng ea thepa e tala, le melemo e mengata. Haholo-holo ka Bophirimela Europe le Amerika Leboea, sekhahla sa kholo ea selemo sa ho roala phofo se fihla ho 10%. Ho feta moo, lilemong tsa morao tjena, China e boetse e bone sekhahla se tsotehang sa kholo ea selemo sa 100% bakeng sa ho roala phofo.

Polyvinyl chloride (PVC) Liaparo tsa Powder li ratoa ka ho khetheha ke basebelisi ka lebaka la thepa ea tsona e ikhethang ea ho khabisa hammoho le boemo ba leholimo le ho hanyetsa ho bola. Hona joale, PVC liaparo tsa phofo li sebelisoa haholo mafapheng a fapaneng ho kenyeletsoa ts'ireletso ea cable ka pipe ea tšepe, phala ea lik'hemik'hale tse thibelang ho senyeha ha lik'hemik'hale, phala ea likhoerekhoere, liphaephe tsa indasteri ea peterole le lik'hemik'hale, matšoao a litsela, lipalo tsa mabone, terene ea litsela tse kholo joalo-joalo.

Ts'ebetso ea Nts'etsopele

1.Motheo oa mokhoa oa ho PVC ho apara ka phofo

PVC ho roala phofo ho entsoe ka PVC resin e le thepa ea motheo e nang le plasticizer, stabilizer, filler le li-additives tse ling. Foromo ea mantlha e bonts'itsoe ho Lethathamo (Mmala o Mosoeu).

2.Boitokisetso Theknoloji ea PVC ho apara ka phofo

Mokhoa oa ho lokisetsa oa PVC ho roala phofo, ts'ebetso ea eona e bontšoa ho Figure.

3.Liphetho tsa Tlhahlobo ea Ts'ebetso ea Sehlahisoa

Ka mor'a repeliphuputso tse hlophisitsoeng le nts'etsopele, liteko, le ho bapisoa le lihlahisoa tse tsoang kantle ho naha, tse ling tsa ts'ebetso ea PVC ho roala phofo qetellong ho fihlile kapa ho feta ts'ebetso ea lihlahisoa tse tsoang kantle ho naha tsa mofuta o tšoanang, bona tafole.

Ts'ebeliso ea PVC Pipe ea tšepe e koahetsoeng ka phofo

PVC Filimi ea ho roala phofo ke boemo bo thata ba thermoplastic. Ha ho bapisoa le polyethylene, mocheso oa ho qhibiliha le phapang ea mocheso oa ho bola o nyane, kahoo ha o sebelisoa o tlameha ho ela hloko mocheso oa ho baka le nako. Ka lebaka la ho khomarela ha eona hantle, pele e qoelisoa, hangata e lokela ho apesoa ka lera la primer ho eketsa ho khomarela ha seaparo.

1.Thepa e ka sehloohong ea ho roala

• PVC lihlahisoa tsa ho roala phofo li kenyelletsa: lisebelisoa tsa mokhabiso oa ka tlung le lesela le sa keneleng metsi, litanka tsa lik'hemik'hale, fatše, filimi e koahelang, hose ea jareteng le terata.
• Mekhoa ea ts'ebetso e amohela ho kopanya ho omileng, ho bopa ente, ho bopa ha sekoti sa extrusion hollow blowing, calendering, le bethe e nang le metsi qoela.
• E thibelang malakabe (e kenyellelitsoe se thibelang malakabe)
• Ho hanyetsa metsi le lik'hemik'hale, ho hanyetsa botsofali hantle.

2.Mokhoa o moholo oa ho haha ​​le mefuta e mengata ea kopo

PVC ho roala ha phofo ho sebelisoa haholo-holo ka letlooeng la tšepe, setšeng sa polokelo e batang, thepa ea ka tlung ea tšepe, phala ea tšepe joalo-joalo. Ts'ebetso ea ho roala ke haholo-holo ka tsela e latelang:

(1) Phekolo ea pele: phekolo ea phosphate - ho tlosa mafome, phosphating.
(2) Ho roala primer: Koahela primer, kamora ho omisa, botenya ba filimi ea primer ke 5-10μm,
(3) ho fafatsa ka electrostatic kapa ho qoelisoa ka bethe.
4. preheating mocheso :230-290 ℃,10min, filimi botenya: 500um;
Kapa 290 ℃, 5min ntle le preheating, filimi botenya 200um.

PVC Pipe ea tšepe e entsoeng ka tšepe e na le thuso ho petrochemical anti-corrosion, e sebetsang tseleng ea tšireletso ea litsela tse kholo, e sebetsang palo, ka mor'a lilemo tse ngata tsa liphetho tsa kopo li bontša hore PVC ho koaela metsi ho hanyetsa, ho hanyetsa botsofali ba sepakapaka ho lokile, hangata ho fumaneha ka lilemo tse fetang 15, ho felisa bothata ba pente ea borashe hangata, papiso e felletseng ea litšenyehelo tsa eona tse tlase, e sebelisoang lik'hemik'hale tse khahlanong le kutu, e ka sebelisoa hape ka lilemo tse fetang tse hlano, hore mosebelisi a rarolle bothata ba anti-corrosion.
