Lintho tse bonahalang tsa HDPE ke eng? Tlhahlobo e felletseng ea litšobotsi le ts'ebeliso ea polyethylene e phahameng haholo
Lefapheng la lik'hemik'hale, HDPE ke thepa ea bohlokoa ka ho fetisisa, lebitso la eona le feletseng ke Polyethylene e Phahameng-Density (High-Density Polyethylene). HDPE ke eng hantle? Sengoliloeng sena se tla u fa karabo e qaqileng le tlhahlobo e tebileng ea litšobotsi tsa HDPE, ts'ebetso ea eona ea tlhahiso le mefuta e mengata ea lits'ebetso.
Mehopolo ea Motheo le Sebopeho sa Lik'hemik'hale sa HDPE
HDPE ke eng? Ho latela pono ea lik'hemik'hale, HDPE ke polymer ea thermoplastic e entsoeng ke ho eketsoa ha polymerization ea ethylene monomers. Sebopeho sa eona sa limolek'hule se khetholloa ke liketane tse telele tsa polyethylene tse nang le boima bo phahameng ba molek'hule le liketane tse fokolang tsa makala pakeng tsa tsona, e leng se etsang hore ho be le tlhophiso e matla ea limolek'hule. Tokisetso ena e thata ea limolek'hule e fa HDPE letsoalo le phahameng lelapeng la polyethylene, hangata lipakeng tsa 0.940 g/cm³ le 0.970 g/cm³.
Lintho tse phahameng tsa 'mele tsa HDPE
Lisebelisoa tsa HDPE li bonts'a lisebelisoa tse ngata tse ntle tsa 'mele ka lebaka la sebopeho sa eona se ikhethang sa limolek'hule. E na le matla a phahameng le ho tiea 'me e khona ho mamella khatello e phahameng ea mechine, e leng se etsang hore e be e babatsehang ho likopo tse jereng mojaro.HDPE e na le lik'hemik'hale tse babatsehang tse hanyetsanang le lik'hemik'hale, tse etsang hore e be molemo bakeng sa ho boloka lik'hemik'hale.
HDPE e boetse e na le khanyetso e ntle ea mocheso o tlase, e khona ho boloka boima ba eona libakeng tse tlase ho -40 ° C ntle le ho senyeha. E boetse e na le litšobotsi tse ntle tsa ho koala motlakase, tse entseng hore e sebelisoe ho hokela lithapo le likhoele.
Mekhoa ea tlhahiso ea HDPE le mekhoa ea ho sebetsa
Ka mor'a ho utloisisa hore na HDPE ke ea mofuta ofe, a re shebeng mokhoa oa eona oa tlhahiso.HDPE hangata e hlahisoa ke mokhoa o tlaase oa khatello ea polymerisation, ke hore tlas'a maemo a tlaase a khatello, ka Ziegler-Natta catalyst kapa Phillips catalyst e le mohloli o ka sehloohong, ka khase ea khase, tharollo. kapa mekhoa ea slurry polymerization. Mekhoa ena e fella ka HDPE e nang le kristale e tlaase le litekanyetso tse phahameng tsa crystallization, tse hlahisang thepa e phahameng ea polyethylene.
Lisebelisoa tsa HDPE li na le ts'ebetso e ntle ea ts'ebetso 'me li ka bōptjoa ka mekhoa e fapaneng ea ho sebetsa, joalo ka ho bōptjoa ha ente, ho phunya le ho bōptjoa ha extrusion. Ka lebaka leo, HDPE e ka etsoa mefuta e mengata ea lihlahisoa tse kang liphaephe, lifilimi, libotlolo le lijana tsa polasetiki.
Libaka tse fapaneng tsa ts'ebeliso ea HDPE
Ka lebaka la lisebelisoa tse ngata tse ntle tsa HDPE, e sebelisoa haholo liindastering tse fapaneng. Ka indasteri ea liphutheloana, HDPE e atisa ho sebelisoa ha ho etsoa mefuta e sa tšoaneng ea libotlolo tsa polasetiki, libotlolo tsa botlolo, lifilimi tsa ho paka lijo, joalo-joalo Boima ba eona bo phahameng le ho fokotseha ha eona ho tiisa ho boloka nako e telele ea ho paka. Lefapheng la kaho, HDPE e sebelisetsoa ho etsa lipeipi tsa metsi le liphaephe tsa metsi le lipeipi tsa khase, 'me ho bola ha eona le ho hanyetsa tšusumetso ho etsa hore e tšepahale libakeng tse thata.
Lefapheng la temo, HDPE e sebelisetsoa ho etsa lifilimi tsa temo, matlooa a moriti le lihlahisoa tse ling, moo ho hanyetsa ha UV le ho tšoarella ho tiisang tšireletso ea lijalo le chai.HDPE e boetse e sebelisoa haholo ha ho etsoa li-insulation bakeng sa lithapo le likhoele, hammoho le ho mefuta e fapaneng ea litanka le lijana tse hananang le lik'hemik'hale.
Qetello
HDPE ke thepa ea polymer ea thermoplastic e nang le thepa e ntle haholo joalo ka matla a phahameng, khanyetso ea lik'hemik'hale, ho hanyetsa mocheso o tlase le ho sebetsa habonolo. E na le mefuta e mengata ea likopo tsa lik'hemik'hale, kaho, temo le masimo a mang. Haeba u ntse u nahana ka "lisebelisoa tsa HDPE ke eng", u tšepa hore ka sengoloa sena, u na le kutloisiso e felletseng ea litšobotsi le ts'ebeliso ea HDPE, ntle le pelaelo HDPE ke e 'ngoe ea lisebelisoa tsa bohlokoa indastering ea sejoale-joale.
