Leqephe la Polyethylene PE1000 – Le hanela ho roaloa ke UHMWPE
Kakaretso
Leqephe la Polythylene PE 1000 leo hangata le tsejoang e le boima bo phahameng ba limolek'hule, UHMW, kapa UHMWPE, ke e 'ngoe ea polasetiki ea rona ea boenjiniere e tsebahalang haholo. E fana ka khanyetso e ntle khahlanong le ho khoptjoa, lik'hemik'hale, tšusumetso le ho tsofala, 'me e fana ka tšebelisano e fokolang haholo ea khohlano. UHMW hape ha e na chefo, ha e na monko, 'me e hanela mongobo haholo.
Letlapa la polasetiki la UHMW hangata le qaptjoa hore e be metjhini e tsofalang, ditataiso tsa ketane le dikarolo tsa phetoho mme ke polasetiki e tsebahalang ya boenjiniere mesebetsing ya ho lokisa dijo le ho kenya dibotlolong. Dikereiti tse ikgethang tsa PE1000 le tsona di sebediswa ditshebedisong tsa ho sebetsana le thepa e ngata ho kenya di-chute, di-hopper le diteraka tsa ho lahla, ho thusa ho ntlafatsa phallo ya sehlahiswa le ho thibela ho taboha le ho kobeha.

Likaroloana
1. Ntlafatsa ho hanyetsa ho tsofala. E 'ngoe ea litšobotsi tse ikhethang ka ho fetisisa tsa polyethylene ea UHMW ke ho hanyetsa ho tsofala ho hoholo haholo, e leng ntho ea bohlokoa haholo lits'ebetsong tse ngata tsa boenjiniere. Har'a polasetiki eohle, ho hanyetsa ho tsofala ha eona ke eona e ntle ka ho fetisisa, 'me esita le ho hanyetsa ho tsofala ho tloaelehileng ha thepa e mengata ea tšepe (joalo ka tšepe ea carbon, tšepe e sa hloekang, boronse, jj.) ha ho ntle joalo ka eona. Ha boima ba limolek'hule tsa polyethylene bo ntse bo eketseha, thepa e fetoha e sa tsofaleng haholoanyane.
2. Khanyetso e phahameng haholo ea tšusumetso. Matla a tšusumetso ea polyethylene e boima ba limolek'hule bo phahameng haholo a amana le boima ba eona ba limolek'hule. Ha boima ba limolek'hule bo le ka tlase ho limilione tse 2, matla a tšusumetso a eketseha ka keketseho ea boima ba limolek'hule, 'me a fihla sehlohlolong sa hoo e ka bang limilione tse 2. Kamora tlhōrō, matla a tšusumetso a eketseha ka boima ba limolek'hule. e tla fokotseha. Lebaka ke hobane ketane ea limolek'hule ha e tloaeleha 'me e sitisa photocrystallization ea eona, hoo ho nang le sebaka se seholo se se nang sebopeho ka har'a macromolecule, e ka monyang matla a maholo a tšusumetso.
3. Koefficient e tlase ea khohlano. UHMWPE e hanela ho tsofala haholo, e na le koefficient e tlase ea khohlano le ho itlotsa hantle, 'me ke thepa e loketseng bakeng sa li-bearing bushings, li-slider le li-lining.
Tšebeliso ea polyethylene e boima ba limolek'hule e phahameng haholo e le karolo ea khohlano ea lisebelisoa e ke ke ea ntlafatsa bophelo ba eona bo sa tsofaleng feela, empa hape e ka boloka matla.
4. Khanyetso e ntle ea lik'hemik'hale. Polyethylene e boima ba limolek'hule e phahameng haholo e na le khanyetso e ntle ea k'hemik'hale ea ho bola. Ntle le asiti e matla ea nitric le asiti e matla ea sulfuric, e ke ke ea bola litharollong tsohle tsa lye le asiti, 'me e ka sebelisoa ka har'a asiti e matla ea hydrochloric mochesong (80°C, E boetse e tsitsitse ka har'aAsiti ea nitric e ka tlase ho 20%,<75% sulfuric acid, 'me e boetse e tsitsitse ka metsing, ka ho hlatsuoa ka metsi.)
Leha ho le jwalo, polyethylene e boima ba dimolekhule e bonolo haholo ho ruruha ka metsoako e nkhang hamonate kapa e nang le halogenated (haholo-holo tlasa maemo a mocheso o phahameng), kahoo tlhokomelo e khethehileng e lokela ho lefshwa nakong ya tshebediso.
5. Ho monya metsi ho tlase haholo. UHMWPE e na le sekhahla se tlase haholo sa ho monya metsi, ha e monye metsi, ha e ruruhe ka metsing, 'me ha e monye metsi haholo joaloka nylon.
6. Thepa ea mocheso. Ho ea ka mokhoa oa ASTM (mojaro oa 4.6kg/cm2), mocheso oa ho sotha mocheso ke 85℃. Tlas'a mojaro o monyenyane, mocheso oa ts'ebeletso o ka fihla ho 90℃. Maemong a khethehileng, e lumelloa ho sebelisoa mochesong o phahameng. Polyethylene e boima ba limolek'hule ke thepa e nang le matla a maholo, kahoo khanyetso ea eona e tlase le eona e ntle haholo, 'me e ntse e na le tekanyo e itseng ea ho se sebetse mochesong o tlase oa -269 ° C, 'me ha ho na pontšo ea ho senyeha.
7. Thepa ea motlakase. UHMWPE e na le thepa e ntle ea motlakase maemong a fapaneng a mocheso, khanyetso ea eona ea bophahamo ke 10-18CM, motlakase oa eona oa ho senyeha ke 50KV/mm, 'me phetoho ea eona ea dielectric ke 2.3. Maemong a fapaneng a mocheso le maqhubu, thepa ea eona ea motlakase ha e fetohe haholo. Maemong a fapaneng a mocheso o hanelang mocheso, e loketse haholo ho sebelisoa e le thepa ea sebopeho boenjiniereng ba motlakase le thepa liindastering tsa pampiri.
8. Polyethylene e seng chefo e boima ba limolek'hule bo phahameng haholo ha e na tatso, ha e na chefo, ha e na monko, ha e senyehe, 'me e na le potoloho ea 'mele le ho ikamahanya le maemo a 'mele. Lefapha la Lijo le Lithethefatsi la United States (FDA) le Lefapha la Temo la United States (USDA) li lumella hore e sebelisoe ha e kopana le lijo le meriana.
Litšobotsi tsa eona, haholo-holo ho hanyetsa ho tsofala, ho hanyetsa tšusumetso, le thepa ea ho itlotsa, ke tse ntle ka ho fetisisa har'a polasetiki ea boenjiniere.
