Chiyambi cha Polyoxymethylene (POM)

Polyoxymethylene (POM), yomwe imadziwikanso kuti acetal, polyacetal, kapena polyformaldehyde, ndiukadaulo wochita bwino kwambiri wa thermoplastic womwe umadziwika chifukwa cha makina ake apadera komanso kukhazikika kwake. Amagwiritsidwa ntchito kwambiri m'mafakitale omwe amafunikira kulondola komanso kukhazikika, monga zamagalimoto, zamagetsi, zida zamankhwala, ndi katundu wogula.

TheZaposachedwa Sustainable POM Technology: Makalasi Afupiafupi A Cellulose Fiber Reinforced

Posachedwapa polyplastics yawulula mitundu yatsopano ya magiredi a DURACON® POM olimbikitsidwa ndi ulusi wamfupi wa cellulose. Izi zatsopano zimakwaniritsa kufunikira kokulirapo kwa zida zokhazikika popanda kusokoneza magwiridwe antchito. Mosiyana ndi POM yodzaza ndi magalasi, magiredi afupikitsa a cellulose amawonjezera kwambiri ma flexural modulus pomwe amakhala opepuka komanso olimba kwambiri.

Cellulose, chinthu chosadyedwa, chochokera ku bio, chimathandizira kuti chilengedwe chikhale chokhazikika ndipo chimadziwika kuti ndi carbon-negative material yomwe imatenga CO2. Ikaphatikizidwa ndi chitsulo cha kaboni (S45C), magiredi atsopanowa a POM amawonetsa kugundana kocheperako komanso kuvala kocheperako, zomwe zimawapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira kulimba kwambiri komanso kutsetsereka kwabwino kwambiri.

Kodi tingalimbikitse bwanji kukana kwa POM popanda kusiya kuchita kapena kukhazikika?

Kuthana ndi Zovuta Zovala ndi Kukangana mu POM

Ngakhale izi zapita patsogolo, zida zambiri za POM zimakumanabe ndi zovuta zambiri pakuvala ndi kukangana, makamaka pazofunikira kwambiri monga magalimoto, zamagetsi, ndi zinthu zogula.

Ena mwa ambiriNjira zodziwika bwino zomwe zimagwiritsidwa ntchito kukulitsa kukana kwa POMzikuphatikizapo:

1. Zowonjezera za PTFE: Polytetrafluoroethylene (PTFE) ikhoza kuchepetsa kwambiri kukangana ndi kuvala mu POM. Komabe, kuchuluka kwambiri kumatha kufooketsa mphamvu zamakina azinthu, kotero kuti mulingo woyenera ndikofunikira.

Kuphatikiza apo, PTFE ndi gulu la zinthu zomwe zimadziwika kuti per- ndi polyfluoroalkyl substances (PFAS). Chifukwa cha ngozi zomwe zingachitike pazaumoyo komanso zachilengedwe zomwe zimakhudzidwa ndi PFAS, European Chemicals Agency yatulutsa lingaliro kuchokera kumayiko asanu omwe ali membala kuti aletse PFAS yomwe ili ndi atomu imodzi ya kaboni yopangidwa bwino - pafupifupi mamolekyu 10,000 osiyanasiyana, kuphatikiza ma fluoropolymers otchuka. Mayiko omwe ali mamembala akuyenera kuvotera chiletsochi mu 2025. Ngati lingaliro la ku Ulaya silinasinthe, Ngati ndondomekoyi ipitirire popanda kusintha, ingayambitse kusintha kwakukulu pakugwiritsa ntchito ma fluoropolymers wamba monga PTFE ndi PVDF, zomwe zimatipangitsa kufufuza njira zotetezeka komanso njira zatsopano zothetsera mavuto.

2. Mafuta Opangira Mafuta: Molybdenum disulfide, boron nitride, ndi zinthu zina zofananirako zimatha kupanga filimu yosamutsira pamwamba pa POM, kuchepetsa mikangano ndikuwongolera kukana kuvala. Komabe, zowonjezera izi ziyenera kusankhidwa mosamala kuti zipewe kusokoneza kukhazikika kwamafuta a POM.

Mayankho Atsopano a Superior Wear Resistance mu POM

Kwa iwo omwe akufuna kupititsa patsogolo kukana kwa POM, SILIKE imapereka zowonjezera zapadera za eco-Friendly zomwe zimapangidwa kuti zithandizire kulimba komanso kukonza katundu:

1. Silicone Masterbatch (Siloxane Masterbatch)LYSI-311: Mapangidwe a pelletized awa ali ndi 50% ultra-high molecular weight siloxane polima, omwazikana mu POM. Imakulitsa magwiridwe antchito ndi mawonekedwe apamwamba a POM, ndikupangitsa kuti ikhale yowonjezera kuti ipititse patsogolo magwiridwe antchito osiyanasiyana.

 2. Valani Resistance Additive kwa POM mankhwala:Banja la SILIKE lomwe likuchulukirachulukira la zowonjezera za silikoni zimakulitsa kwambiri mawonekedwe a polyoxymethylene (POM).

Ndife onyadira kuwonetsa zowonjezera zathu zaposachedwa kubanja lazowonjezera za silicone,LYSI-701. Silikoni yowonjezera iyi idapangidwa makamaka kuti ilimbikitse kukana kwamafuta a polyoxymethylene (POM). Ndi mawonekedwe ake apadera a poly-siloxane, LYSI-701 imabalalika mofanana mu utomoni wa POM, ndikupanga bwino gawo lopaka mafuta pamwamba. Kupita patsogolo kumeneku kumachepetsa kwambiri kukangana (CoF), komanso kumapangitsanso kuti abrasion ndi kukana kwa mar. Zotsatira zake, LYSI-701 imathandizira kukhazikika komanso moyo wautali wa zida za POM, ndikupangitsa kuti ikhale yankho lofunikira pamagwiritsidwe osiyanasiyana.

Ubwino waukulu wogwiritsa ntchito izizowonjezera za siliconezikuphatikizapo:

1. Kuchepetsa Kugundana: Kapangidwe kake ka polysiloxane kamapanga gawo lopaka mafuta pa POM, kutsitsa kukangana ndi kulimbikitsa kuvala ndi kukana kwa mar, kwinaku akusunga mawonekedwe abwino amakina.

2. Kupititsa patsogolo Ubwino Wokongola: Thezowonjezera za siloxaneimapangitsa kuti pakhale mawonekedwe osalala, kumapangitsa chidwi cha zinthu zomalizidwa.

3. Kukonzekera Kwambiri: iziAnti-abrasion Masterbatchimathandizira kuumbika ndi kumasula katundu, kupititsa patsogolo kupanga bwino komanso mtundu wazinthu.

4. Eco-ochezeka komanso Otetezeka:zowonjezera za siliconeilibe poizoni, yopanda fungo, komanso yokonda zachilengedwe, ikukwaniritsa miyezo ya ROHS ndi REACH zofunika zolembetsa. 

Kugwiritsa ntchito zowonjezera za siloxane mu High-Performance POM Components

IziZowonjezera Zapulasitiki ndi Zosintha za Polimamakamaka LYSI-311 ndi LYSI-701, ndi abwino kwa zigawo za POM zogwira ntchito kwambiri zomwe zimagwiritsidwa ntchito popanga, monga:

·Magiya, Ma Bearings, ndi Malamba Onyamula: Komwe kuvala kukana komanso kulimba ndikofunikira.

·Magalimoto: Kuphatikizira makina okweza mazenera ndi masensa owongolera.

·Katundu Wogula: Zida zapakhomo, zida zamasewera, ndi zinthu zina zomwe zimafuna kukana kuvala kwambiri.

Pophatikizira zowonjezera za silicone mu mapangidwe a POM, opanga POM amatha kusintha kwambiri makina awo komanso moyo wautali wazinthu zawo pomwe amachepetsa kukangana, kuvala, komanso kuwononga chilengedwe.
