POMChipepala cha -C ndi thermoplastic yopangidwa ndi semicrystalline ndipo imadziwika ndi kusakanikirana kochepa komanso mawonekedwe abwino ogwiritsidwa ntchito, komanso mawonekedwe abwino ogwiritsidwa ntchito, osakhudzidwa ndi malo onyowa. Chipepala cha POM chimapereka kukana bwino kwa mankhwala osiyanasiyana kuphatikiza zosungunulira zambiri. Chipepala cha Delrin chimapereka mphamvu zambiri komanso kuuma bwino komanso kusavuta kugwiritsa ntchito makina. AHD imadziwikanso ndi mphamvu zake zapamwamba, kukana kutentha komanso mawonekedwe abwino oletsa kugwedezeka. A Pazigawo zomwe zimafunika kukhala zokhazikika ngakhale zitakumana ndi chinyezi kapena malo onyowa, POM-C imapereka kukana bwino kwa madzi otentha, kutentha ndi mankhwala kuposa POM-H.
Ponena za kukana mankhwala, mapepala a POM ndi abwino kwambiri. Ali ndi kukana kwambiri zinthu zosungunulira, mafuta, mafuta ndi mankhwala ena ambiri, zomwe zimapangitsa kuti akhale abwino kwambiri pazinthu zomwe zimakumana ndi zinthuzi. Mapepala a POM alinso ndi kukhazikika kwakukulu, zomwe zikutanthauza kuti amasunga mawonekedwe ake ndi kukula kwake ngakhale kutentha kwambiri.
Ubwino wina wa mapepala a POM ndi wakuti sayamwa chinyezi kwambiri. Mosiyana ndi mapulasitiki ena ambiri, POM ili ndi chizolowezi chochepa kwambiri choyamwa chinyezi, zomwe zimakhudza mphamvu zake zamakanika ndi zamagetsi. Izi zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo ozizira komwe kulibe vuto la hygroscopicity.

Chimodzi mwa zinthu zabwino kwambiri zaPepala la POMndi mphamvu zake zabwino kwambiri zotsetsereka. Ili ndi mphamvu yochepa yotsetsereka, zomwe zikutanthauza kuti imatsetsereka mosavuta pamwamba pa malo ena popanda kukana kwambiri. Izi zimapangitsa kuti ikhale chisankho chodziwika bwino pa ntchito zomwe zimafuna kuyenda kosalala, kopanda kutsetsereka, monga magiya, mabearing ndi zinthu zina zotsetsereka.
Pepala la POMZimakhalanso ndi kukana kuvala kwambiri, zomwe ndizofunikira kwambiri pakugwiritsa ntchito makina obwerezabwereza. Zitha kupirira kuwonongeka kwa nthawi yayitali komanso kukangana, zomwe zimapangitsa kuti zikhale zolimba. Kuphatikiza apo, POM siimakonda kugwedezeka, zomwe zikutanthauza kuti imasunga mawonekedwe ake komanso kukhazikika ngakhale ikapanikizika kwa nthawi yayitali.
Kutha kugwira ntchito ndi chinthu china chabwino cha mapepala a POM. Angathe kupangidwa mosavuta pogwiritsa ntchito njira zachikhalidwe zopangira monga kugaya, kutembenuza ndi kuboola. Izi zimathandiza kuti pakhale kupanga zinthu zovuta komanso zolondola mosavuta. Mapepala a POM ali ndi mphamvu zamagetsi komanso zamagetsi, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito poteteza magetsi.
At KUPITA KUMENE, timapereka mitundu yosiyanasiyana ya POM. Mapepala athu a POM amapangidwa kuchokera ku zinthu zomwe sizili bwino zomwe zimatsimikizira kuti ndi zapamwamba komanso zogwira ntchito bwino. Amapezeka m'makulidwe osiyanasiyana kuyambira 0.5mm mpaka 200mm, okhala ndi mulifupi wokhazikika wa 1000mm ndi kutalika kwa 2000mm. Timapereka mitundu yoyera ndi yakuda, kapena tikhoza kusintha mitundu malinga ndi zomwe mukufuna.
Kaya mukufuna mapepala a POM a zida zamakanika, zotetezera magetsi kapena ntchito ina iliyonse, mapepala athu apamwamba a POM angakwaniritse zosowa zanu. Ndi makhalidwe awo abwino kwambiri a makina, kukana mankhwala komanso kukhazikika kwa miyeso, mapepala athu a POM amapereka magwiridwe antchito abwino komanso kudalirika. Lumikizanani nafe lero kuti mudziwe zambiri za zinthu zathu za mapepala a POM ndi momwe angathandizire polojekiti yanu.
