Kodi Polyphenylene Sulfidi (PPS) ndi chiyani?

Polyphenylene Sulfide (PPS) ndi polima wa thermoplastic semi-crystalline wokhala ndi mawonekedwe achikasu. Ili ndi malo osungunuka pafupifupi 290 ° C ndi kachulukidwe kozungulira 1.35 g/cm³. Msana wake wa mamolekyulu—wopangidwa ndi mphete zosinthasintha za benzene ndi maatomu a sulfure—umapangitsa kuti ikhale yolimba komanso yokhazikika kwambiri.

PPS imadziwika ndi kuuma kwake kwakukulu, kukhazikika kwamafuta, kukana kwamankhwala, komanso mphamvu zamakina. Chifukwa cha ntchito zake zabwino kwambiri, PPS imadziwika kuti ndi imodzi mwa mapulasitiki akuluakulu asanu ndi limodzi, pamodzi ndi polyethylene terephthalate (PET), nayiloni (PA), polycarbonate (PC), polyoxymethylene (POM), ndi polyphenylene ether (PPO).

Mafomu ndi Kugwiritsa Ntchito PPS

Zogulitsa za Polyphenylene Sulfide (PPS) zimapezeka m'mitundu ndi magiredi osiyanasiyana, monga ma resin, ulusi, filaments, mafilimu, ndi zokutira, zomwe zimapangitsa kuti zikhale zosunthika kwambiri. Magawo akuluakulu ogwiritsira ntchito PPS akuphatikiza makampani opanga magalimoto, zamagetsi ndi zamagetsi, makampani opanga mankhwala, asitikali ndi chitetezo, gawo la nsalu, komanso kuteteza chilengedwe.

Mavuto Odziwika mu PPSemapulasitiki a injiniya andi Momwe Mungathetsere

Ngakhale zili ndi zinthu zabwino kwambiri, mapulasitiki aukadaulo a PPS amakumanabe ndi zovuta zingapo zogwirira ntchito komanso magwiridwe antchito. Nazi zinthu zitatu zomwe zimakonda kwambiri komanso mayankho ake ofanana:

1. Kukhumudwa mu PPS Yosadzaza

Chovuta: PPS yosadzazidwa ndi yolimba, imalepheretsa kugwiritsidwa ntchito kwake pamapulogalamu omwe amafunikira kukana kapena kusinthasintha (mwachitsanzo, zigawo zomwe zimagwedezeka kapena kugwedezeka).

Zoyambitsa:

Kutalikira pang'ono panthawi yopuma chifukwa cha mawonekedwe ake olimba a ma cell.

Kupanda zowonjezera kuti muwonjezere kulimba.

Zothetsera:

Gwiritsani ntchito magiredi olimbikitsidwa a PPS okhala ndi magalasi (monga 40% odzazidwa ndi magalasi) kapena zodzaza mchere kuti muwonjezere mphamvu ndi kulimba.

Phatikizani ndi ma elastomers kapena zosintha zamphamvu pazogwiritsa ntchito zina.

2. Kusakhazikika kwa Zopaka kapena Kumangirira

Chovuta: Kusakhazikika kwamankhwala kwa PPS kumapangitsa kuti zikhale zovuta kuti zomatira, zokutira, kapena utoto kumamatira, kuphatikiza kusokoneza kapena kumaliza pamwamba (mwachitsanzo, m'nyumba zamagetsi kapena zida zokutira zamafakitale).

Zoyambitsa:

Mphamvu zochepa zapamtunda chifukwa cha mawonekedwe a PPS omwe si a polar.

Kukaniza kulumikizana ndi mankhwala kapena kunyowetsa pamwamba.

Zothetsera:

Ikani mankhwala ochizira pamwamba monga plasma etching, corona discharge, kapena chemical priming kuti muwonjezere mphamvu pamwamba.

Gwiritsani ntchito zomatira zapadera (mwachitsanzo, epoxy kapena polyurethane-based) zopangidwira PPS.

3 . Wear and Friction in Dynamic Applications

Chovuta: Magiredi osadzaza kapena okhazikika a PPS amawonetsa mavalidwe okwera kapena kukangana m'zigawo zosuntha monga ma fani, magiya, kapena zosindikizira, zomwe zimatsogolera kulephera msanga pakugwiritsa ntchito mphamvu.

Camachitira:

Kulimbana kwakukulu kokwanira mu PPS yosadzazidwa.

Mafuta ochepa pansi pa katundu wambiri kapena kuyenda kosalekeza.

Zothetsera:

Sankhanimafuta PPS amakalasi ndi zowonjezeramonga PTFE, graphite, kapena molybdenum disulfide kuti muchepetse mikangano ndikuwonjezera kukana kuvala.

Gwiritsani ntchito magiredi olimbikitsidwa (mwachitsanzo, odzaza kaboni fiber) kuti muthe kunyamula katundu wambiri.

SILIKE Lubricant Processing Aids ndi Zosintha Zapamwamba za PPS Engineering Plastics

Mayankho Atsopano Othandizira Kulimbana ndi Wear Resistance ya PPS Sliding Components

Kuyambitsa zowonjezera zowonjezera za silicone SILIKE LYSI-530A ndi SILIMER 0110

LYSI-530A ndi SILIMER 0110 ndi zida zatsopano zopangira mafuta komanso zosintha zaposachedwa za polyphenylene sulfide (PPS), zomwe zakhazikitsidwa posachedwa ndi SILIKE. Zowonjezera za silicone zimagwira ntchito mofanana ndi polytetrafluoroethylene (PTFE), zomwe zimadziwika ndi mphamvu zawo zochepa. Zotsatira zake, amachepetsa kwambiri kuchuluka kwa mavalidwe komanso kugundana kwamagulu a PPS.

Zowonjezera izi zimawonetsa kugundana kotsika kwambiri ndipo zimagwira ntchito ngati zothira mkati. Amapanga filimu yopyapyala pamwamba pa PPS akamameta ubweya, potero amachepetsa kukangana pakati pa PPS ndi malo okwerera, mosasamala kanthu kuti ndi zitsulo kapena pulasitiki.

Pogwiritsa ntchito 3% LYSI-530A yokha, kugunda kwamphamvu kumatha kuchepetsedwa mpaka 0.158, zomwe zimapangitsa kuti pakhale malo osalala.

Kuphatikiza apo, kuwonjezera kwa 3% SILIMER 0110 kutha kupeza koyambira kocheperako kozungulira 0.191 pomwe kumapereka kukana kofanana kwa abrasion ndi komwe kumaperekedwa ndi 10% PTFE. Izi zikuwonetsa mphamvu ndi kuthekera kwa zowonjezera izi pakuwongolera magwiridwe antchito ndi kulimba pamapulogalamu osiyanasiyana, Zoyenera kusuntha, kuzungulira, kapena kudzaza magawo a PPS.

SILIKE imapereka magwiridwe antchito apamwambamafuta opangira silicon ndi othandizira pokonzakwa ntchito zosiyanasiyana zamapulasitiki. Zowonjezera zathu zidapangidwa kuti zithandizire kukonza bwino komanso kupititsa patsogolo zinthu zam'mwamba mu mapulasitiki osinthidwa ndi mankhwala.

Mukuyang'ana chowonjezera choyenera pamapangidwe anu? Sankhani SILIKE - mayankho athu ozikidwa pa silikoni angakudabwitseni ndi momwe amagwirira ntchito.
Limbikitsani magwiridwe antchito a PPS ndi zowonjezera za silikoni zomwe zimachepetsa kukangana ndi kuvala - palibe PTFE yofunikira.
