Har'a lipatlisiso le nts'etsopele e ntseng e eketseha le boqapi ba polasetiki ea boenjiniere, lakane ea polyethylene e nang le sekgahla se phahameng (HDPE), ka lebaka la ts'ebetso ea eona e phahameng, e fetoha thepa e khethiloeng masimong a kaho, boenjiniere ba lik'hemik'hale, ts'ireletso ea tikoloho le mechini. Ka melemo ea eona e ikhethang joalo ka matla a phahameng, ho hanyetsa mafome, le bonolo ba ho e sebetsana,Leqephe la HDPEe hlalositse bocha ponahalo ea thepa ea boenjiniere.
I. Tshebetso e Phahameng
1. Matla a Phahameng le Khanyetso ea Ts'enyeho
Leqephe la HDPEE na le boima ba hoo e ka bang 0.94-0.98 g/cm³ le tekanyo e phahameng ea kristale ea 80%. Liketane tsa eona tse teteaneng tsa limolek'hule li e fa thepa e ntle ea mechine. Matla a eona a ho thaepa ke ≥20 MPa, matla a eona a ho teneha ≥24 MPa, 'me ho lelefala ha eona ha e robeha ho ka fihla ho 500%, ho e nolofalletsa ho mamella meroalo e phahameng le ho bontša khanyetso e ikhethang ea tšusumetso. Ho feta moo, leqephe la HDPE le hanela litharollo tsa asiti le alkaline tse kang hydrochloric acid le sodium hydroxide, hammoho le li-solvents tsa organic, mochesong oa kamore. ka 60°C, leqephe la HDPE le ke ke la fetoha, Sena se etsa hore e be khetho e phethahetseng bakeng sa lits'ebetso masimong a ts'ireletso ea lik'hemik'hale le tikoloho.
2. E sireletsa tikoloho le polokeho
HDPE ha e na chefo ebile ha e na monko, 'me e fetile mangolo a mangata a Eco-friendly le polokeho ea lijo, e leng se etsang hore e be thepa e eco-friendly. Ke khetho e ratoang bakeng sa ho seha maqephe lifekthering tsa ho sebetsana le lijo le lipolaong.
II. Likopo tse ngata
1. Meaho le Lehae
Leqephe la HDPE le sebelisa mokhoa oa "ho bopa extrusion + ho khabisa ka nepo", e leng se fellang ka sebopeho se se nang sekoli sa bokaholimo se kopanang hantle le leqephe ka bolona, se thibelang ho petsoha le ho petsoha. Ho eketsoa ha masterbatch e hananang le UV ho sireletsa khahlanong le tšenyo ea UV, ho eketsa nako ea ts'ebeletso ea eona ea kantle. E loketse meaho ea kantle le mekhabiso ea kahare.
Maqephe a sandwich a HDPE a nang le mekhahlelo e 'meli ke khetho e ratoang bakeng sa lisebelisoa tsa lebala la lipapali.
2. Indasteri le Thepa
Maqephe a HDPEli sebelisoa indastering ea lik'hemik'hale bakeng sa liphaephe le litanka.
Lefapheng la thepa, li sebelisoa e le li-shelf liner, li-pallet, li-truck liner, li-bunker liner tsa mashala, le li-chute liner. Litšobotsi tsa tsona tse bobebe, tse hanelang ho tsofala, tse hanelang ho thulana, le tse monyang metsi a fokolang li ntlafatsa haholo katleho ea tsona.
Limmate tsa tšireletso ea mobu tsa HDPE li bobebe ebile ha li mafome, e leng se etsang hore li sebelisoe haholo ho katong litsela, ho nosetsa temo le libakeng tsa kaho.
Ka tsoelo-pele theknolojing ea polasetiki ea boenjiniere, moralo le nts'etsopele ea maqephe a HDPE li ntse li ntlafatsoa khafetsa. Nakong e tlang, maqephe a HDPE a tla nts'etsapele ho ea ho bobebe, ts'ebetsong le ho iketsetsa lintho ho fihlela litlhoko tse fapaneng. Ka motsoako oa eona o phethahetseng oa ts'ebetso le ts'ebeliso, maqephe a HDPE a fetoha phetoho e kholo lefapheng la polasetiki e ncha ea boenjiniere.
Ka tsoelo-pele theknolojing ea boenjiniere ea polasetiki, moralo le nts'etsopele ea maqephe a HDPE li ntse li ntlafatsoa khafetsa. Nakong e tlang,Maqephe a HDPEe tla ntshetsa pele ho lebisa ho bobebe, ho sebetsa hantle, le ho iketsetsa dintho ho fihlela ditlhoko tse fapaneng. Ka motswako wa yona o phethahetseng wa tshebetso le tshebediso, maqephe a HDPE a fetoha phetoho e kgolo lefapheng la dipolasetiki tse ntjha tsa boenjiniere.
Ebang ke kahong, indastering, tshireletsong ya tikoloho, difofaneng, kapa mafapheng a mang, maqephe a HDPE, ka ho sebetsa ha ona, botsoalle ba tikoloho, le boqapi, a ntse a atolosa menyetla ya bophelo ba sejwalejwale. Ho kgetha maqephe a HDPE ho bolela ho kgetha bokamoso bo sebetsang hantle le bo tsitsitseng.
