Kuyini i-Polyphenylene Sulfide (PPS)?

I-Polyphenylene Sulfide (PPS) iyi-polymer ye-thermoplastic e-semi-crystalline ebonakala iphuzi elikhanyayo. Inephuzu lokuncibilika elingaba ngu-290°C kanye nobuningi obungaba ngu-1.35 g/cm³. Umgogodla wayo wama-molecule—owakhiwe ngamasongo e-benzene ashintshanayo nama-athomu esibabule—uyenza ibe nesakhiwo esiqinile nesizinzile kakhulu.

I-PPS yaziwa ngobulukhuni bayo obuphezulu, ukuzinza okuhle kakhulu kokushisa, ukumelana namakhemikhali, kanye namandla omshini. Ngenxa yokusebenza kwayo okuvelele, i-PPS yaziwa kabanzi njengenye yepulasitiki eziyisithupha ezinkulu zobunjiniyela, kanye ne-polyethylene terephthalate (PET), i-nylon (PA), i-polycarbonate (PC), i-polyoxymethylene (POM), kanye ne-polyphenylene ether (PPO).

Amafomu kanye nokusetshenziswa kwe-PPS

Imikhiqizo ye-Polyphenylene Sulfide (PPS) itholakala ngezindlela ezahlukene kanye namazinga, njenge-resin, imicu, ama-filament, amafilimu, kanye nokwemboza, okwenza kube nokuguquguquka okukhulu. Izindawo ezisetshenziswa kakhulu ze-PPS zifaka phakathi imboni yezimoto, kagesi kanye ne-elekthronikhi, imboni yamakhemikhali, ezempi kanye nezokuvikela, imboni yezindwangu, kanye nokuvikelwa kwemvelo.

Izinselele Ezivamile ku-PPSeamapulasitiki obunjiniyelaIndlela Yokuzixazulula

Naphezu kwezakhiwo zayo ezinhle kakhulu, amapulasitiki obunjiniyela be-PPS asabhekene nezinselele eziningana zokucubungula nokusebenza kahle ekusetshenzisweni okungokoqobo. Nazi izinkinga ezintathu ezivame kakhulu kanye nezixazululo zazo ezihambisanayo:

1. Ukungabi nalutho ku-Unfilled PPS

Inselele: I-PPS engagcwalisiwe ibuthakathaka ngokwemvelo, inciphisa ukusetshenziswa kwayo ezicelweni ezidinga ukumelana okukhulu noma ukuguquguquka (isb., izingxenye ezithintekayo ukushaqeka noma ukudlidliza).

Izimbangela:

Ukwelulwa okuphansi lapho iphuka ngenxa yesakhiwo sayo sama-molecule esiqinile.

Ukuntuleka kwezithasiselo zokuthuthukisa ukuqina.

Izixazululo:

Sebenzisa amazinga e-PPS aqinisiwe nge-fiber yengilazi (isb., egcwele ingilazi engu-40%) noma izigcwalisi zamaminerali ukuze uthuthukise amandla okushaya kanye nokuqina.

Hlanganisa nama-elastomer noma ama-impact modifiers ezinhlelweni ezithile.

2. Ukunamathela Okubi Kwezimbozo Noma Ukubopha

Inselele: Ukungangeni kwamakhemikhali kwe-PPS kwenza kube nzima ukuthi izinto zokunamathisela, izinto zokumboza, noma upende zinamathele, okwenza kube nzima ukuhlanganisa noma ukuqeda indawo (isb., ezindaweni zikagesi noma ezingxenyeni zezimboni ezimbozwe nge-coated).

Izimbangela:

Amandla aphansi omhlaba ngenxa yesakhiwo samakhemikhali esingeyona i-polar se-PPS.

Ukumelana nokubopha kwamakhemikhali noma ukumanziswa komhlaba.

Izixazululo:

Sebenzisa izindlela zokwelapha ubuso njengokugqwala nge-plasma, ukukhishwa kwe-corona, noma ukufakelwa kwamakhemikhali ukuze wandise amandla obuso.

Sebenzisa izinamathiseli ezikhethekile (isib., ezisekelwe ku-epoxy noma ku-polyurethane) ezenzelwe i-PPS.

3. Ukuguga Nokungqubuzana Ezinhlelweni Zokusebenza Ezishintshayo

Inselele: Amabanga e-PPS angagcwalisiwe noma ajwayelekile abonisa amazinga aphezulu okuguguleka noma ukungqubuzana ezingxenyeni ezihambayo ezifana nama-bearings, amagiya, noma izivalo, okuholela ekuhlulekeni kwangaphambi kwesikhathi ekusetshenzisweni okuguquguqukayo.

Cizithasiselo:

I-coefficient ephezulu kakhulu yokungqubuzana ku-PPS engagcwalisiwe.

Ukuthambisa okulinganiselwe ngaphansi kwemithwalo ephezulu noma ukunyakaza okuqhubekayo.

Izixazululo:

Khethaamazinga e-PPS agcotshwe ngezithasiselonjenge-PTFE, i-graphite, noma i-molybdenum disulfide ukunciphisa ukungqubuzana nokuthuthukisa ukumelana nokuguguleka.

Sebenzisa amazinga aqinisiwe (isb., agcwele i-carbon fiber) ukuze uthole amandla aphezulu okuthwala umthwalo.

Izinsiza Zokucubungula Ama-Lubricant e-SILIKE kanye Neziguquli Zomphezulu Zepulasitiki Yobunjiniyela be-PPS

Izixazululo Ezintsha Zokuthuthukisa Ukumelana Nokuguguleka Kwezingxenye Ezishelelayo ze-PPS

Sethula izithasiselo ezisekelwe ku-silicone i-SILIKE LYSI-530A kanye ne-SILIMER 0110

I-LYSI-530A kanye ne-SILIMER 0110 ziyizinsiza ezintsha zokucubungula amafutha kanye neziguquli zomphezulu ze-polyphenylene sulfide (PPS), ezisanda kwethulwa yi-SILIKE. Lezi zithasiselo ezisekelwe ku-silicone zisebenza ngendlela efanayo ne-polytetrafluoroethylene (PTFE), ebonakala ngamandla azo aphansi omphezulu. Ngenxa yalokho, zinciphisa kakhulu izinga lokuguguleka kanye ne-coefficient yokungqubuzana kwama-composites e-PPS.

Lezi zithasiselo zibonisa i-coefficient ephansi kakhulu yokungqubuzana futhi zisebenza njengezithambisi zangaphakathi. Zikhiqiza ifilimu elincane ebusweni be-PPS uma zibhekene namandla okunqunywa, ngaleyo ndlela zinciphisa ukungqubuzana phakathi kwe-PPS nezindawo zokuhlangana, kungakhathaliseki ukuthi ziyinsimbi noma ipulasitiki.

Ngokusebenzisa i-3% LYSI-530A kuphela, i-dynamic friction coefficient ingancishiswa ibe cishe ngu-0.158, okuholela endaweni ebushelelezi.

Ngaphezu kwalokho, ukwengezwa kwe-3% SILIMER 0110 kungathola i-coefficient ephansi yokungqubuzana engaba ngu-0.191 ngenkathi kunikeza ukumelana okulinganayo kokuguguleka nalokho okunikezwa yi-10% PTFE. Lokhu kubonisa ukusebenza kahle kanye nekhono lalezi zithasiselo ekuthuthukiseni ukusebenza kanye nokuqina kuzo zonke izinhlelo zokusebenza ezahlukahlukene, Kuhle kakhulu ezingxenyeni ze-PPS ezishelelayo, ezijikelezayo, noma ezilayishwe ngokuguquguqukayo.

I-SILIKE inikeza ukusebenza okuphezuluamafutha okugcoba asekelwe ku-silicone kanye nezinsiza zokucubungulaukuze kusetshenziswe izinhlobo eziningi zepulasitiki. Izithasiselo zethu zenzelwe ukuthuthukisa ukusebenza kahle kokucubungula nokuthuthukisa izakhiwo zomphezulu kumapulasitiki aguquliwe kanye nama-compound.

Ufuna isithasiselo esifanele sefomula yakho? Khetha i-SILIKE — izixazululo zethu ezisekelwe ku-silicone zingase zikumangaze ngokusebenza kwazo.
Thuthukisa ukusebenza kwe-PPS ngezithasiselo ezisekelwe ku-silicone ezinciphisa ukungqubuzana nokuguguleka — akudingeki i-PTFE.
