Chiyambi cha Polyoxymethylene (POM)

Polyoxymethylene (POM), yomwe imadziwikanso kuti acetal, polyacetal, kapena polyformaldehyde, ndi thermoplastic yopangidwa mwaukadaulo yodziwika bwino chifukwa cha mphamvu zake zapadera zamakanika komanso kukhazikika kwa mawonekedwe ake. Imagwiritsidwa ntchito kwambiri m'mafakitale omwe amafunikira kulondola komanso kulimba, monga magalimoto, zamagetsi, zida zamankhwala, ndi zinthu zogwiritsidwa ntchito ndi anthu.

TheUkadaulo Waposachedwa wa POM Wokhazikika: Magiredi Afupi a Cellulose Fiber Olimbikitsidwa

Posachedwapa, Polyplastics yavumbulutsa mitundu yatsopano ya DURACON® POM grade yolimbikitsidwa ndi ulusi wa cellulose waufupi. Lusoli likuthandizira kufunikira kwakukulu kwa zipangizo zokhazikika popanda kusokoneza magwiridwe antchito. Mosiyana ndi POM yachikhalidwe yodzazidwa ndi galasi, mitundu iyi ya ulusi wa cellulose-reinforced imawonjezera kwambiri flexural modulus pamene ikukhalabe yopepuka komanso yolimba kwambiri.

Cellulose, chinthu chosadyedwa, chochokera ku zamoyo, chimathandizira kukhazikika kwa chilengedwe ndipo chimadziwika kuti ndi chinthu chopanda kaboni chomwe chimayamwa CO2. Chikaphatikizidwa ndi chitsulo cha kaboni (S45C), mitundu yatsopano ya POM iyi imakhala ndi mphamvu yochepa yolimbana ndi kusweka komanso kuchepa kwa kuwonongeka, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito molimbika kwambiri komanso kutsetsereka bwino.

Kodi tingatani kuti tiwonjezere kukana kwa POM popanda kuwononga magwiridwe antchito kapena kukhazikika?

Kuthana ndi Mavuto Okhudzana ndi Kuvala ndi Kukangana mu POM

Ngakhale kupita patsogolo kumeneku, zipangizo zambiri za POM zikukumanabe ndi mavuto aakulu okhudzana ndi kuwonongeka ndi kukangana, makamaka pa ntchito zomwe zimafunidwa kwambiri monga magalimoto, zamagetsi, ndi zinthu zogwiritsidwa ntchito.

Zina mwa zodziwika kwambirinjira zodziwika bwino zomwe zimagwiritsidwa ntchito powonjezera kukana kwa POMkuphatikizapo:

1. Zowonjezera za PTFE: Polytetrafluoroethylene (PTFE) imatha kuchepetsa kwambiri kukangana ndi kuwonongeka kwa POM. Komabe, kuchuluka kwambiri kumatha kufooketsa mphamvu ya makina a chinthucho, kotero mlingo woyenera ndi wofunikira.

Kuphatikiza apo, PTFE ndi ya gulu la zinthu zomwe zimadziwika kuti per- ndi polyfluoroalkyl substances (PFAS). Chifukwa cha zoopsa zomwe zingachitike pa thanzi komanso chilengedwe zomwe zimagwirizana ndi PFAS, European Chemicals Agency yafalitsa lingaliro lochokera kumayiko asanu omwe ali mamembala kuti aletse PFAS yomwe ili ndi atomu imodzi ya kaboni yokhala ndi fluorine - mamolekyu osiyanasiyana okwana 10,000, kuphatikiza ma fluoropolymer otchuka. Mayiko omwe ali mamembala akukonzekera kuvota pa chiletsochi mu 2025. Ngati lingaliro la ku Europe silinasinthe, ngati lingaliroli lipitirirabe popanda kusintha, lingayambitse kusintha kwakukulu pakugwiritsa ntchito ma fluoropolymer wamba monga PTFE ndi PVDF, zomwe zikutipangitsa kufufuza njira zina zotetezeka komanso njira zatsopano zothetsera mavuto.

2. Mafuta Opangira Zinthu Zosapangidwa: Molybdenum disulfide, boron nitride, ndi zinthu zina zofanana zopanga zinthu zosapangidwa zimatha kupanga filimu yosamutsira pamwamba pa POM, zomwe zimachepetsa kukangana ndikuwongolera kukana kwa kuwonongeka. Komabe, zowonjezerazi ziyenera kusankhidwa mosamala kuti zisawononge kukhazikika kwa kutentha kwa POM.

Mayankho Atsopano Othana ndi Kutopa Kwambiri mu POM

Kwa iwo omwe akufuna kupititsa patsogolo kukana kwa POM, SILIKE imapereka zowonjezera zapadera zosamalira chilengedwe zomwe zimapangidwa kuti ziwongolere kulimba ndi kukonza zinthu:

1. Silikoni Masterbatch (Siloxane Masterbatch)LYSI-311: Fomula iyi yokhala ndi ma pellet ili ndi 50% ultra-high molecular weight siloxane polymer, yogawidwa mu POM. Imawonjezera mphamvu zogwirira ntchito komanso ubwino wa pamwamba pa POM, zomwe zimapangitsa kuti ikhale yowonjezera yothandiza kwambiri pakukweza magwiridwe antchito m'njira zosiyanasiyana.

 2. Chowonjezera Chotsutsana ndi Kuvala cha mankhwala a POM:Gulu la SILIKE lomwe likukula la zowonjezera za silicone limakulitsa kwambiri mawonekedwe a pamwamba a mankhwala a polyoxymethylene (POM).

Tikunyadira kudziwitsa banja lathu laposachedwa lazowonjezera za silicone,LYSI-701. Chowonjezera chatsopano cha silicone ichi chapangidwa makamaka kuti chiwonjezere kukana kwa polyoxymethylene (POM) kutopa. Ndi kapangidwe kake kapadera ka poly-siloxane, LYSI-701 imafalikira mofanana mu utomoni wa POM, ndikupanga bwino mafuta pamwamba. Kupita patsogolo kumeneku kumachepetsa kwambiri coefficient of friction (CoF), komanso kumawonjezera kukana kwa kukwawa ndi kuuma. Zotsatira zake, LYSI-701 imathandizira kulimba konse ndi moyo wautali wa zinthu za POM, zomwe zimapangitsa kuti ikhale yankho lothandiza pa ntchito zosiyanasiyana.

Ubwino Waukulu Wogwiritsa Ntchito Izizowonjezera za silikonikuphatikizapo:

1. Kuchepetsa Kukangana: Kapangidwe ka polysiloxane kapadera kamapanga mafuta opaka pa POM, kuchepetsa kukangana ndi kuwonjezera kutopa ndi kukana kwa mabala, pomwe kumasunga mawonekedwe abwino kwambiri a makina.

2. Ubwino Wokongoletsa:chowonjezera cha siloxaneZimapatsa mawonekedwe osalala pamwamba, zomwe zimapangitsa kuti zinthu zomalizidwa ziwoneke bwino.

3. Kukonza Koyenera: iziMasterbatch Yotsutsa Kutupakumawonjezera kuthekera kopanga zinthu molimba komanso kutulutsa zinthu, zomwe zimapangitsa kuti zinthu zizigwira bwino ntchito komanso kuti zinthu zizigwira bwino ntchito.

4. Yotetezeka komanso Yopanda Chilengedwe:zowonjezera za silikoniSili ndi poizoni, silinunkhiza, komanso siliwononga chilengedwe, likukwaniritsa miyezo ya ROHS ndi zofunikira za REACH zolembetsera pasadakhale. 

Kugwiritsa ntchito zowonjezera za siloxane mu High-Performance POM Components

IziZowonjezera za Plastiki ndi Zosintha za Polymermakamaka LYSI-311 ndi LYSI-701, ndi abwino kwambiri pazida za POM zomwe zimagwiritsidwa ntchito popanga zinthu, monga:

·Magiya, Mabearing, ndi Malamba Ogulitsira: Kumene kukana kuwonongeka ndi kulimba ndikofunikira kwambiri.

·Magalimoto: Kuphatikizapo makina okweza mawindo ndi masensa oyendetsera.

·Katundu wa Kagwiritsidwe Ntchito: Zipangizo zapakhomo, zida zamasewera, ndi zinthu zina zomwe zimafuna kulimba kwambiri.

Mwa kuphatikiza zowonjezera zopangidwa ndi silicone izi mu mapangidwe a POM, opanga POM amatha kusintha kwambiri mawonekedwe a makina ndi moyo wautali wa zinthu zawo pomwe akuchepetsa kukangana, kuvala, komanso kuwononga chilengedwe.

(Chengdu SILIKE Technology Co., Ltd imadziwika kwambiri popereka mitundu yonse ya zowonjezera za silicone ndi Non-PFAS Process Aids za mapulasitiki osinthidwa. Mayankho awo atsopano adapangidwa kuti awonjezere magwiridwe antchito ndi magwiridwe antchito a zinthu zapulasitiki, zomwe zimapangitsa kuti akhale mnzawo wofunika kwa iwo omwe akufuna kukonza zinthu zawo.)
