Molamu oa POM

Tlhaloso ea tlhahiso

---

  Molamu oa POM ke mofuta oa ketane ea mahlakoreng e sa lefelloeng, e nang le sekhahla se phahameng, copolymer e phahameng ea kristale e nang le thepa e phethahetseng.

  POM board ke thepa e thata le e teteaneng e nang le bokaholimo bo boreleli le bo khanyang, bo ntšo kapa bo tšoeu, bo ka sebelisoang nako e telele mocheso oa mocheso oa - 40 - 106 ° C. Ho hanyetsa ha eona le ho itlotsa ka bohona ho boetse ho phahametse ba bangata. polasetiki ea boenjiniere, 'me e na le khanyetso e ntle ea oli le ho hanyetsa peroxide. E hanyetsana haholo le mahlaseli a acid, alkali le ultraviolet.

  POM ke polasetiki ea kristale e nang le ntlha e hlakileng ea ho qhibiliha. Hang ha e fihla sebakeng sa ho qhibiliha, viscosity ea qhibiliha e theoha ka potlako. Ha mocheso o feta moeli o itseng kapa ho qhibiliha ho futhumala nako e telele, ho tla baka ho bola.

  POM e na le thepa e ntle e felletseng. Ke eona e thata ka ho fetisisa har'a thermoplastics. Ke e 'ngoe ea mefuta e sa tšoaneng ea thepa ea polasetiki eo thepa ea eona ea mechine e leng haufi le tšepe. Matla a eona a tsitsitseng, matla a ho koba, matla a mokhathala, ho hanyetsa ho roala le thepa ea motlakase e ntle haholo. E ka sebelisoa nako e telele pakeng tsa -40 ° C le 100 ° C.

  Molamu oa polyoxymethylene e na le matla a phahameng a mochine, boima bo phahameng, boima bo phahameng, elasticity e babatsehang, ho thella le ho hanyetsa ho tsuba, ho hanyetsa ho tsuba, esita le ka mocheso o tlaase, matla a matla a matla, botsitso bo botle ba sebopeho, ts'ebetso e babatsehang ea mochine, inertia ea physiological, e loketseng ho kopana le lijo. Sekhomaretsi se tloaelehileng sa epoxy resin AB se ke ke sa sebelisoa bakeng sa ho kopanya.

  POM-C/H (e ntšo le e tšoeu): li emela POM copolymer le POM homopolymer ka ho latellana. POM copolymer e na le sebaka se tlase sa ho qhibiliha, botsitso ba mocheso, k'hemik'hale ea kutu ea lik'hemik'hale, litšobotsi tsa phallo, ho hanyetsa hydrolysis, khanyetso e matla ea alkali le ho senyeha ha oxidation ea mocheso, 'me ts'ebetso ea eona e molemo ho feta homoformaldehyde. Homopolymer ea POM e na le kristale e phahameng, e thellang, katoloso e tlase ea mocheso, ho hanyetsa ho roala, matla a mochini, ho tiea le mocheso oa mocheso ho feta copolymer formaldehyde. (Hajoale, POM-C copolymerization e sebelisoa haholo bakeng sa lihlahisoa tse felileng tsa POM 'marakeng)

 

kopo
