Iyini i-Polyphenylene Sulfidi (PPS)?

I-Polyphenylene Sulfide (PPS) i-semi-crystalline thermoplastic polymer enokubukeka okuphuzi okuphaphathekile. Inephuzu lokuncibilika elicishe libe ngu-290°C kanye nokuminyana okungaba ngu-1.35 g/cm³. Umgogodla wayo wamangqamuzana—owenziwe izindandatho ze-benzene ezishintshanayo nama-athomu esibabule—uwenza ube nesakhiwo esiqinile nesizinze kakhulu.

I-PPS yaziwa ngobulukhuni bayo obuphezulu, ukuzinza okuhle kakhulu kokushisa, ukumelana namakhemikhali, namandla emishini. Ngenxa yokusebenza kwayo okuvelele, i-PPS yaziwa kabanzi njengenye yepulasitiki enkulu yobunjiniyela eyisithupha, eduze kwe-polyethylene terephthalate (PET), inayiloni (PA), i-polycarbonate (PC), i-polyoxymethylene (POM), ne-polyphenylene ether (PPO).

Amafomu kanye Nezicelo ze-PPS

Imikhiqizo ye-Polyphenylene Sulfide (PPS) itholakala ngezinhlobo namabanga ahlukahlukene, njengama-resin, amafayibha, imicu, amafilimu, kanye nama-coatings, okwenza kube nezinto ezihlukahlukene kakhulu. Izindawo ezisetshenziswa kakhulu ze-PPS zifaka imboni yezimoto, imboni kagesi neye-elekthronikhi, imboni yamakhemikhali, ezempi nezokuvikela, imboni yendwangu, kanye nokuvikelwa kwemvelo.

Izinselelo Ezijwayelekile ku-PPSeubunjiniyela bepulasitiki akanye Nendlela Yokuzixazulula

Naphezu kwezakhiwo zayo ezinhle kakhulu, amapulasitiki obunjiniyela be-PPS asabhekene nezinselelo ezimbalwa zokucubungula nokusebenza ekusebenzeni okusebenzayo. Nazi izinto ezintathu ezivame kakhulu nezisombululo zazo ezihambisanayo:

1. Ukuqina ku-PPS Engagcwalisiwe

Inselele: I-PPS engagcwalisiwe i-brittle ngokwemvelo, ikhawulela ukusetshenziswa kwayo ezinhlelweni ezidinga ukumelana nomthelela ophezulu noma ukuguquguquka (isb., izingxenye ezingaphansi kokushaqeka noma ukudlidliza).

Izimbangela:

Ubude obuphansi ngesikhathi sekhefu ngenxa yesakhiwo sayo samangqamuzana aqinile.

Ukuntuleka kwezithasiselo zokuthuthukisa ukuqina.

Izixazululo:

Sebenzisa amamaki e-PPS aqinisiwe ane-fiber yengilazi (isb., u-40% ogcwele ingilazi) noma izigcwalisi zamaminerali ukuze uthuthukise amandla okuthinta kanye nokuqina.

Hlanganisa nama-elastomer noma izishintshi zomthelela zezinhlelo zokusebenza ezithile.

2. Ukunamathela Okungalungile Kwezingubo Zokunamathela noma Ukubopha

Inselele: Ukungangeni kwamakhemikhali kwe-PPS kwenza kube nzima ukuthi izinto ezinamathelayo, okokunamathelayo, noma upende ukunamathela, ukuhlanganisa okuyinkimbinkimbi noma ukuqedwa kwangaphezulu (isb., ezindlini zikagesi noma izingxenye zezimboni ezimboziwe).

Izimbangela:

Amandla aphansi angaphezulu ngenxa yesakhiwo samakhemikhali esingeyona indawo ye-PPS.

Ukumelana nokuhlangana kwamakhemikhali noma ukumanziswa kwendawo.

Izixazululo:

Sebenzisa ukwelapha okungaphezulu okufana ne-plasma etching, ukukhishwa kwe-corona, noma i-chemical priming ukuze ukhulise amandla angaphezulu.

Sebenzisa izinto ezinamathelayo ezikhethekile (isb., i-epoxy noma i-polyurethane-based) eyenzelwe i-PPS.

3 . I-Wear and Friction in Dynamic Applications

Inselele: Amamaki e-PPS angagcwalisiwe noma ajwayelekile abonisa ukuguga okuphezulu noma ukungqubuzana ezingxenyeni ezihambayo njengama-bheringi, amagiya, noma ama-seal, okuholela ekwehlulekeni ngaphambi kwesikhathi ezinhlelweni zokusebenza eziguqukayo.

Csebenzisa:

I-coefficient ephezulu ngokuqhathaniswa yokungqubuzana ku-PPS engagcwalisiwe.

I-lubricity enomkhawulo ngaphansi kwemithwalo ephezulu noma ukunyakaza okuqhubekayo.

Izixazululo:

Khethaamamaki e-PPS agcotshiwe anezithasiselonjenge-PTFE, i-graphite, noma i-molybdenum disulfide ukunciphisa ukungqubuzana nokuthuthukisa ukumelana nokugqokwa.

Sebenzisa amamaki aqinisiwe (isb, agcwaliswe i-carbon fibre) ukuze uthole umthamo ophezulu wokuthwala.

I-SILIKE Izinsiza Zokucubungula I-Lubricant kanye Nezimodifitha Zaphezulu zePPS Engineering Plastics

Izixazululo Ezintsha Zokuthuthukisa I-Wear Resistance ye-PPS Sliding Components

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

I-LYSI-530A kanye ne-SILIMER 0110 ziyizinsiza ezintsha zokucubungula amafutha kanye nezilungisi zangaphezulu ze-polyphenylene sulfide (PPS), ezisanda kwethulwa yi-SILIKE. Lezi zithako ezisekelwe ku-silicone zisebenza ngokufana ne-polytetrafluoroethylene (PTFE), ezibonakala ngamandla azo angaphezulu aphansi. Ngenxa yalokho, banciphisa kakhulu kokubili izinga lokuguga kanye ne-coefficient yokungqubuzana kwezinhlanganisela ze-PPS.

Lezi zengezo zibonisa i-coefficient ephansi kakhulu yokungqubuzana futhi zisebenza njengezithambisi zangaphakathi. Bakha ifilimu elincanyana ebusweni be-PPS lapho bebhekene namandla okugunda, ngaleyo ndlela banciphise ukungqubuzana phakathi kwe-PPS nezindawo zokukhwelana, kungakhathaliseki ukuthi ziyinsimbi noma zepulasitiki.

Ngokusebenzisa nje u-3% LYSI-530A, i-dynamic coefficient ingancishiswa ibe cishe ku-0.158, okuholela endaweni ebushelelezi.

Ukwengeza, okungeziwe okungu-3% SILIMER 0110 kungathola i-coefficient ephansi yokungqubuzana okungaba ngu-0.191 kuyilapho inikeza ukumelana okufanayo kokuhuzuka kulokho okunikezwa ngu-10% PTFE. Lokhu kubonisa ukusebenza kahle namandla alezi zengezo ekuthuthukiseni ukusebenza nokuqina kuzo zonke izinhlelo zokusebenza ezihlukahlukene, Ilungele ukuslayida, ukuzungezisa, noma izingxenye ze-PPS ezilayishwe ngamandla.

I-SILIKE inikeza ukusebenza okuphezuluama-lubricant asekelwe ku-silicone kanye nezinsiza zokucubungulakwezinhlobonhlobo zezicelo zepulasitiki. Izithasiselo zethu zenzelwe ukuthuthukisa ukusebenza kahle kokucubungula kanye nokuthuthukisa izakhiwo ezingaphezulu kumapulasitiki aguquliwe nezinhlanganisela.

Ingabe ufuna isithasiselo esifanele ekwenziweni kwakho? Khetha i-SILIKE - izixazululo zethu ezisekelwe ku-silicone zingase zikumangaze ngokusebenza kwazo.
Thuthukisa ukusebenza kwe-PPS ngezithasiselo ezisekelwe ku-silicone ezinciphisa ukungqubuzana nokuguga — ayikho i-PTFE edingekayo.
