Lintho tse sa Bapisoeng tsa Barrier
EVOH, e tsejoang ka litšoaneleho tsa eona tse ikhethang tsa thibelo khahlano le likhase tse kang oksijene, naetrojene le carbon dioxide, e fetola papali ea ho paka lijo.Bokhoni ba eona ba ho thibela ho kenella ha oksijene bo boloka ho nchafala ha lijo, ho lelefatsa bophelo ba sethala, le ho boloka tatso e nepahetseng.Sena se etsa hore EVOH e be khetho e nepahetseng bakeng sa lihlahisoa tse hlokolosi joalo ka lebese, nama le lijo tse seng li loketse ho jeoa.
Bokamoso bo tsitsitseng
Ho MEIFENG, ha se feela ho fihlela litlhoko tsa hajoale;re mabapi le ho bopa bokamoso.Ho fallela ha rona ho lisebelisoa tsa EVOH tse nang le lithibelo tse phahameng ho bonahatsa boinehelo ba rona ho bobeli boqapi le tlhokomelo ea tikoloho.Ka ho fana ka liphutheloana tse sireletsang haholo le tse tšoarellang, re kenya letsoho indastering e tala, e tšoarellang haholoanyane.
Ka ho amohela ka pele-pele ea boqapi ba ho paka, mokhoa oa rona oa ho sebelisa EVOH o fetohile haholo.Ho e-na le ho sebelisa EVOH e le lesela le ikemetseng, hona joale re sebelisa mokhoa o rarahaneng oa co-extrusion o kopanyang EVOH le PE (Polyethylene).Mokhoa ona oa boqapi o theha thepa e kopaneng, e ka sebelisoang hape, e nolofatsang ts'ebetso ea ho e sebelisa hape le ho matlafatsa ts'ireletso ea tikoloho ea lihlahisoa tsa rona.Motsoako ona o kopantsoeng oa EVOH-PE ha o boloke feela litšobotsi tse ikhethang tsa lithibelo tsa EVOH empa hape o matlafatsa ho tšoarella le ho tenyetseha ha PE.Sephetho ke thepa ea ho paka e fanang ka tšireletso e phahameng bakeng sa lihlahisoa tsa lijo ha re ntse re tšehetsa boinehelo ba rona ho boikarabello ba tikoloho le botsitso indastering ea liphutheloana tsa polasetiki.
Lisebelisoa tse fapaneng
Litharollo tsa rona tsa liphutheloana tse ntlafalitsoeng tsa EVOH li sebetsa ka mokhoa o makatsang.Li fana ka mefuta e mengata ea lihlahisoa tsa lijo, ho tloha ho metsi ho isa ho tse tiileng, 'me li ikamahanya le mefuta e fapaneng ea ho paka - e ka ba mekotla, mekotla kapa liphutheloana.Ho feto-fetoha ha maemo ha EVOH ho kopantsoe le mekhoa ea rona ea tlhahiso ea morao-rao e re lumella ho finyella litlhoko tse sa tšoaneng tsa indasteri ea lijo.

Ha re ntse re tsoela pele ho hlahloba le ho kenya ts'ebetsong litharollo tsa motheo tsa ho paka lijo, re u mema hore u be le rona leetong lena le monate.Khetha MEIFENG bakeng sa sephutheloana se sirelletsang, se bolokang, le se sebetsang, ha se ntse se betla tsela bakeng sa bokamoso bo tsitsitseng.
