Mekhoa ea ntlafatso ea nakong e tlang ea ho roala phofo ea polyethylene

Polyethylene phofo ke ntho ea bohlokoa haholo ea maiketsetso, e leng motsoako oa polymer o entsoeng ho tloha ethylene monomer 'me o sebelisoa haholo ha ho etsoa lihlahisoa tsa polasetiki, likhoele, lijana, liphaephe, lithapo, lithapo le masimo a mang. Ka kenyelletso e tsoelang pele ea lisebelisoa tse ncha le theknoloji e ncha, tšebeliso ea phofo ea polyethylene e boetse e atoloha. Mekhoa ea ntlafatso ea nakong e tlang e tla ba ka tsela e latelang:

1. Mokhoa oa ts'ireletso ea botala le tikoloho: Ka tlhokomeliso e ntseng e eketseha ea ts'ireletso ea tikoloho, mokhoa oa nts'etsopele ea botala le ts'ireletso ea tikoloho e fetohile tataiso ea bohlokoa bakeng sa nts'etsopele ea nakong e tlang ea polyethylene. Ho laola ho tsoa le ho phekoloa ha lintho tse kotsi ka tlhahiso ea phofo ke e 'ngoe ea litsela tsa ho finyella tšireletso e tala le ea tikoloho ea polyethylene. Hona joale, tlhahiso ea extruded polyethylene phofo generally e sebelisa lisebelisoa tse tala tsa petrochemical, tse nang le mathata a hlahelletseng a tikoloho. Ho sebelisa lisebelisoa tsa polyethylene tse tsosolositsoeng ho hlahisa polyethylene e tla ba mokhoa o atlehang oa ho fokotsa litšenyehelo tsa tlhahiso ha u ntse u finyella tšireletso ea tikoloho.

2. Matla a phahameng le mokhoa o phahameng oa ho tiea: Matla le ho tiea ha phofo ea polyethylene ke matšoao a bohlokoa a ts'ebetso ea lihlahisoa. Nakong e tlang, likopo tse ngata le ho feta li tla hloka hore polyethylene e be le matla a phahameng le ho tiea. Likarolong tsa bohlokoa tse kang thepa ea kaho, tlhahiso ea likoloi, lisebelisoa tsa sefofane, lisebelisoa tsa elektronike le lintho tsa ho bapala, li-powders tsa polyethylene tse nang le tikoloho tse nang le matla a phahameng, boima bo phahameng, ho hanyetsa likhohlano le ho roala ho hanyetsa ho tla hlokahala. Ka hona, theknoloji ea ho itokisa le ts'ebetso ea tlhahiso ea phofo ea polyethylene e tla tsoela pele ho ntshetsa pele ho ea ho matla a phahameng le boima bo phahameng.

3. Mekhoa e mengata: Sepheo sa ho qetela sa nts'etsopele ea mekhoa e mengata ea polyethylene powders ke ho ntlafatsa 'mele, lik'hemik'hale, mechine, mocheso le lisebelisoa tse ling tse fapa-fapaneng. Nakong e tlang, ka ho hlaha ha liindasteri tse ncha le khōlo ea theknoloji e fapaneng, polyethylene e tla tsoela pele ho ntshetsa pele ho ea ho litsela tse ngata tse sebetsang. Polyethylene phofo e ka kopanngoa le ea karal li-fillers, li-fiber reinforcement systems le lisebelisoa tse ling, ka katleho li ntlafatsa ho hanyetsa mocheso, ho hanyetsa oxidation, botsitso ba lik'hemik'hale le ho hanyetsa kutu, 'me e na le menyetla e mengata ea ts'ebeliso.

4. Tloaelo e phahameng ea litšenyehelo: Nakong e tlang, polyethylene e tla phehella litšenyehelo tse phahameng tsa litšenyehelo, tse bonahalang haholo-holo ts'ebetsong ea tlhahiso. Le hoja ho fokotsa litšenyehelo, boleng le bona bo tlameha ho tiisetsoa, ​​e leng motheo oa ho ntlafatsa tlhōlisano. Liphoofolo tsa polyethylene li tla ba le taolo e ntle le theknoloji ea tlhahiso e ikemetseng nakong e tlang, e tla ntlafatsa katleho ea tlhahiso ha

5, mokhoa oa mefuta e fapaneng ea mefuta. Nakong e tlang, mefuta e sa tšoaneng ea phofo ea polyethylene e tla fetoha mefuta-futa, haholo-holo e bontšoa likarolong tsa sebopeho sa lik'hemik'hale, morphology le thepa ea rheological. Liaparo tsa phofo tsa Thermoplastic e tla hlahisa mefuta e fapaneng ho ea ka litlhoko tsa masimo a fapaneng a ts'ebetso, joalo ka polyethylene e phahameng haholo, polyethylene e tlase-tlase, polyethylene ea linear low-density, le mefuta e meng. Ka nako e ts'oanang, ho tla hlaha mefuta e mecha e kang lisebelisoa tse ncha tse kopantsoeng, li-polymer alloys le lisebelisoa tse entsoeng ka motsoako. Mefuta e fapaneng ea nako e tlang e tla khotsofatsa tlhoko ea 'maraka.

Ka bokhutšoanyane, mokhoa oa nts'etsopele ea phofo ea polyethylene nakong e tlang e tla tsoela pele ka potlako ho lebisa tlhokomelo ea tikoloho, matla a phahameng le ho tiea, ho sebetsa ka mekhoa e mengata, ho ba le litšenyehelo tse phahameng, le mefuta-futa ea mefuta e sa tšoaneng. Monyetla oa 'maraka oa phofo ea polyethylene o tla ba kholoanyane le ho feta,' me tebello ea indasteri e khanyang.
