Letlapa la pom la delrin la 1mm 5mm POM le atolositsoeng
Qaqiso ea Sehlahisoa:
Polyoxymethylene (POM) ke polymer e feto-fetohang e sebelisoang haholo indastering e fapaneng ka lebaka la thepa ea eona e ntle haholo. E 'ngoe ea lihlahisoa tse tsebahalang haholo tsa POM ke lakane ea POM, e tsejoang ka matla a eona a holimo, thepa e ntle ea ho thella le ho hanyetsa ho tsofala hantle. Empa ke eng hantle e etsang hore lakane ea POM e be e ikhethang hakaale?
Ntlha ea pele,Leqephe la POMLi tiile haholo ebile li tiile, e leng se etsang hore li be ntle bakeng sa lits'ebetso tse hlokang ho tiea haholo. Ka lebaka la matla a eona a phahameng a ho thula, esita le mochesong o tlase, maqephe a POM a ka mamella khatello e ngata ntle le ho petsoha kapa ho robeha, e leng se etsang hore a tšepahale haholo ebile a tšoarelle nako e telele.
Molemo o mong o moholo oa maqephe a POM ke ho monya ha ona mongobo o fokolang. Boemong bo tletseng, maqephe a POM a monya feela hoo e ka bang 0.8% ea mongobo, ho bolelang hore a hanela mongobo haholo le tšenyo e amanang le mongobo. Sena se etsa hore a be matle bakeng sa tšebeliso lits'ebetsong moo ho pepesehela mongobo e leng bothata bo ka bang teng.
Ho phaella moo, maqephe a POM a tsebahala ka ho hanyetsa ho tsofala ha ona hantle le thepa ea ho thella. Matla a phahameng le bokaholimo bo boreleli ba leqephe la POM bo etsa bonnete ba hore le hanela ho taboha le ho hohloka haholo, e leng se etsang hore e be ntle bakeng sa tšebeliso lits'ebetsong moo khohlano e leng bothata bo boholo.
Maqephe a POM le ona a ka sebelisoa ka mokhoa o rarahaneng haholo, ho bolelang hore a ka sehoa habonolo, a bōptjoa le ho bōptjoa hore a lumellane le mefuta e mengata ea lits'ebetso. Sena se etsa hore a be le mekhoa e mengata 'me a lokele libaka tse fapaneng tsa indasteri.
Ho phaella moo,Leqephe la POMLi na le khanyetso e ntle ea ho thekesela, e leng se bolelang hore li ke ke tsa fetoha kapa tsa fetoha ha nako e ntse e ea. Li boetse li na le botsitso bo boholo, bo netefatsang hore li boloka sebopeho le boholo ba tsona bo nepahetseng ka mor'a ho sehoa kapa ho etsoa ka mochini.
Maqephe a POM le ona a hanela haholo ho hasana ha metsi, ho bolelang hore a ka mamella ho pepesehela metsi nako e telele ntle le ho senyeha. Ha e le hantle, POM-C (copolymer) e na le botsitso bo phahameng ba mocheso le ho hanyetsa lik'hemik'hale haholo, ho kenyeletsoa le ha ho hasana ha metsi.
Qetellong, maqephe a POM a na le matla a ho mamella le ho tenyetseha ha ho hlaphoheloa, e leng se netefatsang hore a ka kgutlela morao ho tloha phetohong efe kapa efe kapa tshusumetsong ntle le ho lahlehelwa ke sebopeho kapa tshebetso ya ona.
Ka bokhutšoanyane, leqephe la POM ke polymer e feto-fetohang le e tšepahalang e ka sebelisoang lits'ebetsong tse fapaneng. Matla a tsona a ikhethang, ho hanyetsa ho tsofala, botsitso ba boholo le ho sebetsa habonolo li etsa hore li be ntle bakeng sa libaka tsa indasteri moo ho tiea le ho tšoarella e leng litaba tsa bohlokoa. Maqephe a POM a hanela mongobo le hydrolysis haholo, 'me a mamella haholo ebile aa tšoarella, e leng se etsang hore e be a bohlokoa bakeng sa projeke efe kapa efe e tebileng ea indasteri.
