Polyoxymethylene (POM) ndi mtundu wa pulasitiki wauinjiniya womwe umagwira bwino ntchito, umadziwika kunja monga "Duracon" ndi "Super Steel". POM yapamwamba yosamva kuvala imakhala ndi kuuma, mphamvu ndi kulimba kofanana ndi chitsulo. Imakhala ndi mafuta odzipaka bwino, kukana kutopa komanso kusungunuka mumitundu yosiyanasiyana ya kutentha ndi chinyezi. Komanso, ali wabwino mankhwala kukana. Ruiyuan Engineering Plastics adayambitsa POM yosamva kuvala kwambiri pamtengo wotsika kuposa mapulasitiki ena ambiri auinjiniya. Ikulowa m'malo mwa misika ina yomwe nthawi zambiri imakhala ndi zitsulo, monga kusintha zinki, mkuwa, aluminiyamu ndi chitsulo kupanga magawo ambiri. Kuyambira maonekedwe ake, High kuvala zosagwira POM wakhala chimagwiritsidwa ntchito zamagetsi, makina, maonekedwe, tsiku makampani kuwala, magalimoto, zomangira, ulimi ndi zina. M'magawo ambiri atsopano ogwiritsira ntchito, monga luso lachipatala, zipangizo zamasewera, ndi zina zotero, POM yosamva kuvala kwambiri imasonyezanso kukula kwabwino.
Makhalidwe apamwamba a POM osamva kuvala:
1. POM yapamwamba yosamva kuvala ndi pulasitiki ya crystalline yokhala ndi malo osungunuka osungunuka. Pamene malo osungunuka afika, kusungunuka kwa viscosity kumachepa mofulumira.
2. POM yapamwamba yosamva kuvala imakhala ndi coefficient yotsika kwambiri yotsutsana ndi kukhazikika kwa geometric, ndipo imakhala yoyenera kwambiri popanga zida ndi ma bere.
3. POM yosamva kuvala yapamwamba imakhala ndi kutentha kwakukulu, choncho imagwiritsidwanso ntchito pazida zamapaipi (ma valves a mapaipi, nyumba zapampu), zipangizo za udzu, ndi zina zotero.
4. POM yapamwamba yosamva kuvala ndi zinthu zolimba komanso zotanuka, zomwe zimakhalabe ndi kukana kwabwino kwa kukwawa, kukhazikika kwa geometric ndi kukana kwamphamvu ngakhale kutentha kochepa.
5. Kuchuluka kwa crystallization ya POM yosamva kuvala kwambiri kumapangitsa kuti pakhale kuchepa kwakukulu, komwe kumatha kufika 2% mpaka 3.5%. Pali mitundu yofupikitsa yosiyanasiyana ya data yowonjezereka
Pankhani ya kukana mankhwala,Chithunzi cha POMndi bwino. 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 zake zabwino kwambiri kutsetsereka. 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 kwa mawonekedwe, mapepala athu a POM amapereka magwiridwe antchito komanso kudalirika. Lumikizanani nafe lero kuti mudziwe zambiri zamapepala athu a POM ndi momwe angapindulire polojekiti yanu.
