CNC Machining mu POM
Pulasitiki ndi zinthu zina zomwe zimagwiritsidwa ntchito potembenuza CNC chifukwa zimapezeka muzosankha zambiri, ndizotsika mtengo, ndipo zimakhala ndi nthawi yothamanga mwachangu.Mapulasitiki omwe amagwiritsidwa ntchito kwambiri ndi ABS, acrylic, polycarbonate ndi nayiloni.
POM (Polyoxymethylene) Kufotokozera
POM, yomwe imadziwikanso kuti acetal kapena Delrin, ndi chinthu cha thermoplastic chokhala ndi semi-crystalline properties.Amayamikiridwa kwambiri chifukwa cha mphamvu zake zapadera, kuuma kwake komanso kutsika kwamphamvu.POM imagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe amafunikira kulondola komanso kutsika kochepa.
Kugwiritsa ntchito
POM, yomwe imadziwikanso kuti acetal kapena Delrin, ndi chinthu chosunthika cha thermoplastic chomwe chimagwiritsidwa ntchito pazinthu zosiyanasiyana.Makhalidwe ake apadera amachititsa kuti akhale abwino popanga magiya ndi ma bere mu makina amakina.Zida zamagalimoto, monga zida zamafuta ndi mkati, zimapindulanso ndi kulimba kwa POM komanso kukana.Kuphatikiza apo, POM yabwino kwambiri yotsekera magetsi imapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazolumikizira zamagetsi.Pomaliza, mphamvu ya POM ndi moyo wautali zimapangitsa kuti ikhale chisankho chokonda kupanga zinthu zogula monga zipi, zoseweretsa ndi ziwiya zakukhitchini.
Mphamvu
Zinthuzo zimakhala ndi mphamvu zochititsa chidwi ndipo zimatha kupirira mphamvu zazikulu zamakina.Amapereka kuyenda kosalala ndi kukangana kochepa komanso kugonjetsedwa kuvala.Imasunga mawonekedwe ake ndi miyeso muzochitika zonse, kuonetsetsa bata.Kuphatikiza apo, imalimbana ndi zotsatira za mankhwala ndipo imatha kupirira kukhudzana ndi zinthu zosiyanasiyana popanda kuwonongeka.
Zofooka
Zinthuzo zimakhala ndi zotsutsana zochepa ndi ma radiation a UV motero zimatha kuwonongeka pakapita nthawi yayitali ku dzuwa.Komanso, sachedwa kupsinjika ming'alu pamikhalidwe ina.

Zambiri zasayansi zodziwika bwino za POM
POM (Polyoxymethylene), yomwe imadziwikanso kuti acetal, ndi pulasitiki yogwira ntchito kwambiri.Ndi semi-crystalline thermoplastic yomwe imapereka mphamvu zamakina, kuuma, komanso kukhazikika kwa mawonekedwe.POM imagwiritsidwa ntchito kwambiri m'zigawo zolondola, monga magiya, ma bearing, ndi zida zamagalimoto.
POM ili ndi coefficient yotsika ya kukangana, yomwe imapangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafuna kuvala kochepa komanso kukangana.Imalimbana bwino ndi mankhwala, zosungunulira, ndi mafuta, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mafakitale amagalimoto ndi mankhwala.POM ilinso ndi zida zabwino zotchinjiriza magetsi ndipo imatha kupirira kutentha kwambiri.
POM imapezeka m'mitundu iwiri ikuluikulu: homopolymer ndi copolymer.Homopolymer POM imapereka mphamvu zamakina apamwamba komanso kuuma, pomwe copolymer POM imapereka kukana bwino pakuwonongeka kwamafuta ndi kuwukira kwamankhwala.
