Yintoni iPolyphenylene Sulfide (PPS)?

I-Polyphenylene Sulfide (PPS) yi-polymer ye-thermoplastic e-semi-crystalline enembonakalo emthubi okhanyayo. Inendawo yokunyibilika emalunga nama-290°C kunye noxinano olumalunga ne-1.35 g/cm³. Umqolo wayo we-molecular—owenziwe ngee-benzene rings ezitshintshanayo kunye nee-athomu zesulfure—uyenza ibe nesakhiwo esiqinileyo nesizinzileyo.

I-PPS yaziwa ngokuba lukhuni kwayo okuphezulu, uzinzo oluhle kakhulu kubushushu, ukumelana neekhemikhali, kunye namandla oomatshini. Ngenxa yokusebenza kwayo okugqwesileyo, i-PPS yaziwa ngokubanzi njengenye yeeplastiki ezintandathu eziphambili zobunjineli, kunye ne-polyethylene terephthalate (PET), i-nylon (PA), i-polycarbonate (PC), i-polyoxymethylene (POM), kunye ne-polyphenylene ether (PPO).

Iifom kunye nosetyenziso lwe-PPS

Iimveliso zePolyphenylene Sulfide (PPS) ziyafumaneka ngeendlela ezahlukeneyo kunye neendidi, ezifana neeresini, imicu, iifilaments, iifilimu, kunye neengubo, nto leyo eyenza ukuba zibe luncedo kakhulu. Iindawo eziphambili zokusetyenziswa kwePPS ziquka ishishini leemoto, umbane kunye ne-elektroniki, ishishini leekhemikhali, umkhosi kunye nokhuselo, icandelo leempahla, kunye nokukhuselwa kwendalo.

Imingeni eqhelekileyo kwi-PPSeiiplastiki zobunjineliIndlela Yokuzisombulula

Nangona ineempawu ezintle, iiplastiki zobunjineli bePPS zisajongene nemingeni emininzi yokucubungula kunye nokusebenza kwizicelo ezisebenzayo. Nazi ezintathu zezona ngxaki zixhaphakileyo kunye nezisombululo zazo ezifanelekileyo:

1. Uburhabaxa kwi-Unfilled PPS

Umngeni: I-PPS engazaliswanga ibuthathaka ngokwemvelo, nto leyo ethintela ukusetyenziswa kwayo kwizicelo ezifuna ukumelana nempembelelo ephezulu okanye ukuguquguquka (umz., izinto ezinokubangela ukothuka okanye ukungcangcazela).

Izizathu:

Ukwandiswa okuphantsi xa iqhekeka ngenxa yesakhiwo sayo esiqinileyo seemolekyuli.

Ukungabikho kwezongezo zokomeleza ukuqina.

Izisombululo:

Sebenzisa ii-PPS eziqinisiweyo ezinefayibha yeglasi (umz., i-40% yeglasi ezaliswe) okanye izizalisi zeminerali ukuphucula amandla kunye nokuqina kwempembelelo.

Hlanganisa ne-elastomers okanye ii-impact modifiers kwizicelo ezithile.

2. Ukuncamathela kakubi kwiingubo okanye kwiBonding

Umngeni: Ukungangeni kweekhemikhali zePPS kwenza kube nzima ukuba izinto zokuncamathelisa, iipeyinti, okanye iipeyinti zinamathele, nto leyo eyenza kube nzima ukuhlanganisa okanye ukugqiba umphezulu (umz., kwiindawo ze-elektroniki okanye kwiindawo zoshishino ezigqunyiweyo).

Izizathu:

Amandla aphantsi omphezulu ngenxa yesakhiwo seekhemikhali ezingezizo ezomhlaba zePPS.

Ukuchasana nokubopha kweekhemikhali okanye ukumanzisa umphezulu.

Izisombululo:

Faka unyango lomphezulu olufana nokugrumba kweplasma, ukukhupha icorona, okanye ukufakelwa kweekhemikhali ukuze wonyuse amandla omphezulu.

Sebenzisa izincamathelisi ezikhethekileyo (umz., ezisekwe kwi-epoxy okanye kwi-polyurethane) ezenzelwe i-PPS.

3. Ukuguguleka kunye nokungqubana kwizicelo ezitshintshayo

Umngeni: Amanqanaba e-PPS angazaliswanga okanye asemgangathweni abonisa amazinga aphezulu okuguguleka okanye ukungqubana kwiindawo ezihambayo ezifana neebheringi, iigiya, okanye izitywini, okukhokelela ekusileleni kwangethuba kwizicelo eziguqukayo.

Cii-aus:

I-coefficient ephezulu kakhulu yokungqubana kwi-PPS engazaliswanga.

Ukuthambisa okulinganiselweyo xa imithwalo ephezulu okanye intshukumo eqhubekayo.

Izisombululo:

Khethaiiklasi zePPS ezithanjiswe nge-additivesnjenge-PTFE, i-graphite, okanye i-molybdenum disulfide ukunciphisa ukungqubana nokuphucula ukumelana nokuguguleka.

Sebenzisa iigreyidi eziqinisiweyo (umz., ezizaliswe yi-carbon fiber) ukuze ufumane amandla aphezulu okuthwala umthwalo.

Izixhobo Zokulungisa I-SILIKE Lubricant kunye NeeModifiers Zomphezulu WeePlastics Zobunjineli bePPS

Izisombululo Ezintsha Zokuphucula Ukumelana Nokuguguleka Kweenxalenye ze-PPS Sliding

Ukwazisa izongezo ezisekelwe kwi-silicone i-SILIKE LYSI-530A kunye ne-SILIMER 0110

I-LYSI-530A kunye ne-SILIMER 0110 zizixhobo ezintsha zokulungisa i-lubricant kunye neziguquli zomphezulu we-polyphenylene sulfide (PPS), ezisandula ukuqaliswa yi-SILIKE. Ezi zongezo ezisekelwe kwi-silicone zisebenza ngendlela efanayo ne-polytetrafluoroethylene (PTFE), ezibonakaliswa ngamandla azo aphantsi omphezulu. Ngenxa yoko, zinciphisa kakhulu izinga lokuguguleka kunye ne-coefficient yokungqubana kwee-PPS composites.

Ezi zongezo zibonisa umlinganiselo ophantsi kakhulu wokungqubana kwaye zisebenza njengezinto zokuthambisa zangaphakathi. Zivelisa ifilimu encinci kumphezulu we-PPS xa ziphantsi kwamandla okucheba, ngaloo ndlela zinciphisa ukungqubana phakathi kwe-PPS kunye neendawo zokutshatisa, nokuba zezesinyithi okanye zeplastiki.

Ngokusebenzisa i-3% ye-LYSI-530A kuphela, i-dynamic friction coefficient ingancitshiswa ibe malunga ne-0.158, nto leyo ebangela ukuba umphezulu ube bushelelezi.

Ukongeza, ukongezwa kwe-3% SILIMER 0110 kunokufumana i-coefficient ephantsi yokungqubana emalunga ne-0.191 ngelixa kubonelela ngokumelana nokukrala okulinganayo noko kunikezelwa yi-10% PTFE. Oku kubonisa ukusebenza kakuhle kunye nokukwazi kwezi zongezo ekuphuculeni ukusebenza kunye nokuqina kuzo zonke iinkqubo ezahlukeneyo, Ilungele ukutyibilika, ukujikeleza, okanye ukulayishwa ngokuguquguqukayo kweendawo ze-PPS.
