Chii chinonzi Polyphenylene Sulfide (PPS)?

Polyphenylene Sulfide (PPS) ipolymer yethermoplastic yakaita semi-crystalline ine chitarisiko cheyero yakachenuruka. Ine poindi yekunyunguduka inosvika 290°C uye density inosvika 1.35 g/cm³. Musana wayo wemolecular—une rings dzebenzene dzinochinjana uye maatomu esulfur—unoita kuti ive yakasimba uye yakagadzikana.

PPS inozivikanwa nekuoma kwayo kwakanyanya, kugadzikana kwakanyanya pakupisa, kuramba makemikari, uye simba remakanika. Nekuda kwekushanda kwayo kwakanaka, PPS inozivikanwa zvakanyanya seimwe yemapurasitiki matanhatu makuru einjiniya, pamwe chete nepolyethylene terephthalate (PET), nylon (PA), polycarbonate (PC), polyoxymethylene (POM), uye polyphenylene ether (PPO).

Mafomu uye Mashandisirwo ePPS

Zvigadzirwa zvePolyphenylene Sulfide (PPS) zvinowanikwa mumhando dzakasiyana-siyana uye mamakisi, zvakaita semaresini, fibers, filaments, mafirimu, uye coatings, zvichiita kuti zvive zvakasiyana-siyana. Nzvimbo huru dzekushandisa dzePPS dzinosanganisira indasitiri yemotokari, magetsi nemagetsi, indasitiri yemakemikari, mauto nekudzivirira, chikamu chemachira, uye kuchengetedzwa kwezvakatipoteredza.

Matambudziko Akajairika muPPSemapurasitiki ekugadzira zvinhu zveinjiniyauye Maitiro Ekugadzirisa

Pasinei nehunyanzvi hwayo hwakanaka, mapurasitiki ekugadzira ePPS achiri kusangana nematambudziko akati wandei ekugadzirisa uye mashandiro awo mukushandiswa kwawo. Heano matatu ematambudziko akajairika uye mhinduro dzawo dzinoenderana:

1. Kupfava muPPS Isina Kuzadzwa

Dambudziko: PPS isina kuzadzwa inopfava, zvichideredza kushandiswa kwayo mumashandisirwo ayo anoda kuramba kusimba kana kuchinjika zvakanyanya (semuenzaniso, zvikamu zvinogona kuvhunduka kana kudedera).

Zvinokonzera:

Kureba kwakaderera pakuputsika nekuda kwechimiro chayo chakasimba chemamorekuru.

Kushaikwa kwezvinowedzera simba rekuwedzera kusimba.

Mhinduro:

Shandisa maPPS akasimbiswa ane fiber yegirazi (semuenzaniso, 40% yakazadzwa negirazi) kana mamineral fillers kuti uwedzere simba rekusimba uye kusimba kwechinhu chacho.

Sanganisa ne elastomers kana impact modifiers kune mamwe mashandisirwo.

2. Kubata zvisina kunaka pakuputira kana kubatana

Dambudziko: Kusashanda zvakanaka kwemakemikari kwePPS kunoita kuti zviomere kunamira zvinonamira, zvinoputira, kana pendi, zvichiita kuti pave nekuoma kwekubatanidza kana kupedzisa pamusoro (semuenzaniso, mumakamuri emagetsi kana zvikamu zvemaindasitiri zvakaputirwa).

Zvinokonzera:

Simba repamusoro rakaderera nekuda kwechimiro chemakemikari chePPS chisiri chepolar.

Kusabatanidzwa nemakemikari kana kunyoroveswa pamusoro.

Mhinduro:

Isa mishonga yekurapa pamusoro pevhu senge plasma etching, corona discharge, kana chemical priming kuti uwedzere simba pamusoro pevhu.

Shandisa manamatiro akagadzirwa nehunyanzvi (semuenzaniso, epoxy kana polyurethane) akagadzirirwa PPS.

3. Kusashanda uye Kukweshana muDynamic Applications

Dambudziko: Magiredhi ePPS asina kuzadzwa kana akajairwa anoratidza mwero wekupfekwa kwakanyanya kana kukweshana muzvikamu zvinofamba zvakaita semabheyaringi, magiya, kana zvisimbiso, zvichikonzera kutadza kushanda zvakanaka panguva yekushandiswa kwazvinoita.

Cmagwaro:

Kukwikwidzana kwakanyanya muPPS isina kuzadzwa.

Mafuta mashoma kana zvinhu zvakawanda zvichishandiswa kana zvichifamba-famba.

Mhinduro:

Sarudzamagiredhi ePPS akanyoroveswa ane zvinowedzerazvakaita sePTFE, graphite, kana molybdenum disulfide kuderedza kukweshana uye kuwedzera kuramba kupfeka.

Shandisa magiredhi akasimbiswa (semuenzaniso, akazadzwa nefiber yekabhoni) kuti ukwanise kutakura mutoro wakawanda.

Tinounza zvinhu zvinowedzerwa zvesilicone SILIKE LYSI-530A neSILIMER 0110

LYSI-530A naSILIMER 0110 zvinhu zvitsva zvinobatsira pakugadzirisa mafuta uye zvinogadzirisa pamusoro pe polyphenylene sulfide (PPS), zvakaburitswa neSILIKE nguva pfupi yadarika. Izvi zvinowedzerwa zvesilicone zvinoshanda zvakafanana ne polytetrafluoroethylene (PTFE), inozivikanwa nesimba rayo shoma pamusoro. Nekuda kweizvozvo, zvinoderedza zvakanyanya mwero wekupfeka uye coefficient yekukweshana kwePPS composites.

Izvi zvinowedzera zvine mwero wakaderera wekukweshana uye zvinoshanda semafuta emukati. Zvinogadzira firimu rakatetepa pamusoro pePPS kana zvichinge zvachekwa, nokudaro zvichideredza kukweshana pakati pePPS nenzvimbo dzinosangana, zvisinei nekuti dzakaita sesimbi kana kuti dzepurasitiki.

Nekushandisa 3% chete yeLYSI-530A, dynamic friction coefficient inogona kuderedzwa kusvika pa0.158, zvichiita kuti pamusoro payo pave pakanaka.

Pamusoro pezvo, kuwedzerwa kwe3% SILIMER 0110 kunogona kuwana kukwirirana kwakaderera kweinenge 0.191 ukuwo kuchipa kudzivirira kwakaenzana ne10% PTFE. Izvi zvinoratidza kushanda uye kugona kwezvinowedzera izvi mukuvandudza mashandiro uye kugara kwenguva refu muzvishandiso zvakasiyana-siyana, Zvakanakira zvikamu zvePPS zvinotsvedza, zvinotenderera, kana zvinotakura simba.

SILIKE inopa mashandiro epamusoromafuta ekushandisa silicone uye zvinhu zvinobatsira pakugadzirisayemhando dzakasiyana dzemapurasitiki. Zvekuwedzera zvedu zvakagadzirirwa kuvandudza mashandiro ekugadzira uye kuwedzera hunhu hwepamusoro mumapurasitiki akagadziriswa uye macompounds.

Uri kutsvaga chinhu chakakodzera mushonga wako here? Sarudza SILIKE — mhinduro dzedu dzakavakirwa pasilicone dzinogona kukushamisa nekushanda kwadzo.
Wedzera kushanda kwePPS nezvinhu zvinowedzerwa zvakagadzirwa nesilicone zvinoderedza kukweshana uye kupera — hapana PTFE inodiwa.
