POM(polyoxymethylene), yomwe imadziwikanso kuti polyacetal kapena acetal, ndi chinthu chosinthika cha thermoplastic chokhala ndi zinthu zambiri zofunika. Chimodzi mwazinthu zodziwika bwino za pepala la POM ndi luso lake lamakina. Ili ndi kuphatikiza kwapadera kwa mphamvu, kuuma ndi kulimba, zomwe zimapangitsa kuti zikhale zoyenera pa ntchito zosiyanasiyana.
Pankhani ya kukana kwa mankhwala, mapepala a POM amapambana. Ali ndi kukana kwakukulu kwa zosungunulira, mafuta, mafuta ndi mankhwala ena ambiri, zomwe zimapangitsa kuti zikhale zoyenera kwa zigawo zomwe zimagwirizana ndi zinthuzi. Tsamba la POM limakhalanso ndi kukhazikika kwapamwamba, zomwe zikutanthauza kuti limasunga mawonekedwe ake ndi miyeso ngakhale kutentha kwambiri.
Ubwino wina wa mapepala a POM ndi kutsika kwawo kwa chinyezi. Mosiyana ndi mapulasitiki ena ambiri, POM ili ndi chizolowezi chochepa kwambiri chotengera chinyezi, chomwe chimakhudza makina ake ndi magetsi. Izi zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'malo achinyezi pomwe hygroscopicity imadetsa nkhawa.
Chimodzi mwazinthu zodziwika bwino zaChithunzi cha POMndi zinthu zake zabwino kwambiri zotsetsereka. Ili ndi coefficient yotsika ya kukangana, zomwe zikutanthauza kuti imatsetsereka mosavuta pazida zina popanda kukana kwambiri. Izi zimapangitsa kukhala chisankho chodziwika bwino pamapulogalamu omwe amafunikira kuyenda kosalala, kopanda mikangano, monga magiya, ma bearings ndi magawo otsetsereka.
Chithunzi cha POMs alinso ndi kukana kwambiri kuvala, zomwe ndizofunikira kwambiri pamakina okhudzana ndi kusuntha kwamakina mobwerezabwereza. Ikhoza kupirira kuvala kwa nthawi yaitali ndi kukangana, kuzipangitsa kukhala zolimba. Kuonjezera apo, POM sichimakonda kukwawa, zomwe zikutanthauza kuti imasunga mawonekedwe ake ndi kukhazikika ngakhale pansi pa kupsinjika kwa nthawi yaitali.
Machinability ndi mwayi wina wa mapepala a POM. Itha kupangidwa mosavuta ndikupangidwa pogwiritsa ntchito njira zachikhalidwe monga mphero, kutembenuza ndi kubowola. Izi zimathandiza kupanga mosavuta magawo ovuta komanso olondola. Pepala la POM lilinso ndi zinthu zabwino zamagetsi ndi dielectric, zomwe zimapangitsa kuti likhale loyenera kugwiritsa ntchito magetsi.
At KUSINTHA, timapereka zosankha zambiri za POM. Mapepala athu a POM amapangidwa kuchokera ku zinthu zakuthupi zomwe zimatsimikizira kuti zili bwino komanso zimachita bwino. Amapezeka mu makulidwe osiyanasiyana kuchokera ku 0.5mm mpaka 200mm, ndi m'lifupi mwake 1000mm ndi kutalika kwa 2000mm. Timapereka mitundu yoyera ndi yakuda, kapena titha kusintha mitundu malinga ndi zomwe mukufuna.
Kaya mukufuna mapepala a POM azigawo zamakina, zotchingira magetsi kapena ntchito ina iliyonse, mapepala athu apamwamba a POM amatha kukwaniritsa zosowa zanu. Ndi mawonekedwe awo abwino amakina, kukana kwamphamvu kwamankhwala komanso kukhazikika kwapang'onopang'ono, mapepala athu a POM amapereka magwiridwe antchito komanso kudalirika. Lumikizanani nafe lero kuti mudziwe zambiri zamapepala athu a POM ndi momwe angapindulire polojekiti yanu.
