Isingeniso ku-Polyoxymethylene (POM)

I-Polyoxymethylene (POM), eyaziwa nangokuthi i-acetal, i-polyacetal, noma i-polyformaldehyde, iyi-thermoplastic yobunjiniyela esebenza kahle kakhulu eyaziwa ngezakhiwo zayo ezihlukile zemishini kanye nokuqina kobukhulu. Isetshenziswa kabanzi ezimbonini ezidinga ukunemba nokuqina, njengezimoto, izinto zikagesi, amadivayisi ezokwelapha, kanye nezimpahla zabathengi.

IUbuchwepheshe be-POM obuqhubekayo bamuva: Amabanga Amafushane E-Cellulose Fiber Aqinisiwe

I-Polyplastics isanda kwembula uhla olusha lwe-DURACON® POM grades oluqiniswe ngemicu ye-cellulose emifushane. Lokhu kusungula izinto ezintsha kulungisa isidingo esikhulayo sezinto ezihlala isikhathi eside ngaphandle kokuphazamisa ukusebenza kahle. Ngokungafani ne-POM yendabuko egcwele ingilazi, lawa mazinga amafushane aqiniswe nge-cellulose fiber-reinforced akhulisa kakhulu i-flexural modulus ngenkathi egcina ukuqina okulula nokuqinile.

I-Cellulose, into engadliwayo, esekelwe ku-bio, inegalelo ekusimeni kwemvelo futhi ibhekwa njengento engenawo u-carbon emunca i-CO2. Uma ihlanganiswe nensimbi ye-carbon (S45C), lawa ma-POM grade amasha abonisa i-dynamic friction coefficient ephansi kanye nokuguguleka okuncishisiwe, okwenza kube kuhle kakhulu ekusetshenzisweni okudinga ukuqina okuphezulu kanye nezakhiwo ezinhle kakhulu zokushelela.

Singakuthuthukisa kanjani ukumelana nokuguguleka kwe-POM ngaphandle kokunciphisa ukusebenza noma ukusimama?

Ukubhekana Nezinselele Zokuguguleka Nokungqubuzana Ku-POM

Naphezu kwalokhu kuthuthuka, izinto eziningi ze-POM zisabhekene nezinselele ezinkulu zokuguga nokungqubuzana, ikakhulukazi ezicelweni ezifunwa kakhulu njengezimoto, izinto zikagesi, kanye nezimpahla zabathengi.

Ezinye zezinto ezibaluleke kakhuluizindlela ezivamile ezisetshenziswa ukuthuthukisa ukumelana nokuguguleka kwe-POMfaka:

1. Izithasiselo ze-PTFE: I-Polytetrafluoroethylene (PTFE) inganciphisa kakhulu ukungqubuzana nokuguguleka kwe-POM. Kodwa-ke, inani eliningi kakhulu lingenza buthaka amandla emishini yento, ngakho-ke umthamo olinganiselayo ubalulekile.

Ngaphezu kwalokho, i-PTFE ingeyeqembu lezinto ezaziwa ngokuthi izinto ze-per- kanye ne-polyfluoroalkyl (PFAS). Ngenxa yezingozi ezingaba khona zempilo kanye nezemvelo ezihlobene ne-PFAS, i-European Chemicals Agency ishicilele isiphakamiso esivela emazweni amahlanu angamalungu sokuvimbela i-PFAS equkethe okungenani i-athomu eyodwa yekhabhoni egcwele i-fluorine - ama-molecule ahlukene angaba ngu-10,000, kufaka phakathi ama-fluoropolymer athandwayo. Amazwe angamalungu azimisele ukuvota kulokhu kuvinjelwa ngo-2025. Uma isiphakamiso saseYurophu singashintshi, Uma isiphakamiso siqhubeka ngaphandle kwezinguquko, singaholela ezinguqukweni ezibalulekile ekusetshenzisweni kwama-fluoropolymer avamile njenge-PTFE kanye ne-PVDF, okusishukumisela ukuthi sihlole ezinye izindlela eziphephile kanye nezixazululo ezintsha.

2. Izithambisi Ezingaphili: I-Molybdenum disulfide, i-boron nitride, nezinto ezifanayo ezingaphili zingakha ifilimu yokudlulisa ebusweni be-POM, zinciphise ukungqubuzana futhi zithuthukise ukumelana nokuguguleka. Kodwa-ke, lezi zithambisi kumele zikhethwe ngokucophelela ukuze kugwenywe ukwehlisa ukuzinza kokushisa kwe-POM.

Izixazululo Ezintsha Zokumelana Nokugqokwa Okuphezulu ku-POM

Kulabo abafuna ukuthuthukisa ukumelana nokuguguleka kwe-POM, i-SILIKE inikeza uhla lwezithasiselo ezikhethekile ezinobungani nemvelo ezenzelwe ukuthuthukisa ukuqina kanye nezakhiwo zokucubungula:

1. I-Silicone Masterbatch (i-Siloxane Masterbatch)I-LYSI-311: Le fomula efakwe i-pellet iqukethe i-polymer ye-siloxane enesisindo sama-molecule esingu-50% esiphezulu kakhulu, esatshalaliswa ku-POM. Ithuthukisa izakhiwo zokucubungula kanye nekhwalithi yobuso be-POM, okwenza kube yinto esetshenziswa kakhulu ekuthuthukiseni ukusebenza kwezicelo ezahlukahlukene.

 2. Isengezo Sokumelana Nokugqoka sama-POM compounds:Umndeni okhulayo we-SILIKE wezithasiselo ze-silicone uthuthukisa kakhulu izakhiwo zangaphandle zama-compound e-polyoxymethylene (POM).

Siyaziqhenya ngokwethula umngane wethu wakamuva emndenini kaizithasiselo ze-silicone,I-LYSI-701. Lesi sithako se-silicone esisha senzelwe ngqo ukuthuthukisa ukumelana nokuguguleka kwamakhemikhali e-polyoxymethylene (POM). Ngesakhiwo sayo esiyingqayizivele se-poly-siloxane, i-LYSI-701 isakazeka ngokulinganayo kuyo yonke i-POM resin, yakha ngempumelelo ungqimba lokuthambisa ebusweni. Lokhu kuthuthuka kunciphisa kakhulu i-coefficient of friction (CoF), ngenkathi futhi kuthuthukisa ukumelana nokuklwebheka kanye nokonakala. Ngenxa yalokho, i-LYSI-701 inegalelo ekuqineni nasekuphileni isikhathi eside kwezinto ze-POM, okwenza kube yisisombululo esiwusizo sezinhlelo zokusebenza ezahlukahlukene.

Izinzuzo Eziyinhloko Zokusebenzisa Leziizithasiselo ze-siliconefaka:

1. Ukungqubuzana Okuncishisiwe: Isakhiwo se-polysiloxane esiyingqayizivele sakha ungqimba lokugcoba ku-POM, kunciphisa ukungqubuzana futhi kukhulisa ukumelana nokuguguleka kanye nokonakala, ngenkathi kugcinwa izakhiwo ezinhle kakhulu zemishini.

2. Ikhwalithi Yobuhle Ethuthukisiwe: Iisithasiselo se-siloxaneinikeza ukuqeda okubushelelezi kobuso, okuthuthukisa ukubukeka kwemikhiqizo eqediwe.

3. Ukucubungula Okulungiselelwe: lokhuI-Masterbatch yokulwa nokugugulekakuthuthukisa ukubumbeka kanye nezakhiwo zokukhulula, kuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo.

4. Iphephile futhi inobungani nemvelo:izithasiselo ze-siliconeayinobuthi, ayinaphunga, futhi inobungani nemvelo, ihlangabezana nezindinganiso ze-ROHS kanye nezimfuneko zokubhalisa kusengaphambili ze-REACH. 

Ukusetshenziswa kwezithasiselo ze-siloxane ku-High-Performance POM Components

LokhuIzithasiselo zepulasitiki kanye nezilungisi ze-polymerikakhulukazi i-LYSI-311 kanye ne-LYSI-701, zilungele izingxenye ze-POM ezisebenza kahle kakhulu ezisetshenziswa ekukhiqizeni, njenge:

·Amagiya, Amabheringi, Namabhande Okuthutha: Lapho ukumelana nokuguguleka nokuqina kubaluleke kakhulu.

·Izimoto: Kufaka phakathi izinhlelo zokuphakamisa amafasitela kanye nezinzwa zekholomu yokuqondisa.

·Izimpahla Zabathengi: Izinto zasendlini, imishini yezemidlalo, nezinye izinto ezidinga ukumelana nokuguguleka okukhulu.

Ngokufaka lezi zithasiselo ezisekelwe ku-silicone ekwakhiweni kwe-POM, abakhiqizi be-POM bangathuthukisa kakhulu izakhiwo zemishini kanye nobude bemikhiqizo yabo ngenkathi benciphisa ukungqubuzana, ukuguguleka, kanye nomthelela emvelweni.
