Isingeniso se-Polyoxymethylene (POM)

I-Polyoxymethylene (POM), eyaziwa nangokuthi i-acetal, i-polyacetal, noma i-polyformaldehyde, i-thermoplastic yobunjiniyela esebenza kahle kakhulu edume ngezici zayo ezihlukile zokumaka kanye nokuzinza kwe-dimensional. Isetshenziswa kakhulu ezimbonini ezidinga ukunemba nokuqina, njengezezimoto, izinto zikagesi, izisetshenziswa zezokwelapha, nezimpahla zabathengi.

II-POM Technology yakamuva: AmaBanga Aqinisiwe We-Cellulose Fiber

I-Polyplastics isanda kwethula uhla olusha lwamabanga e-DURACON® POM aqiniswe ngemicu emifushane ye-cellulose. Lokhu kusungula kubhekana nesidingo esikhulayo sezinto ezisimeme ngaphandle kokuyekethisa ukusebenza. Ngokungafani ne-POM evamile egcwele ingilazi, lawa mabanga amafushane e-cellulose fiber-reinforced amamaki akhulisa kakhulu imodulus eguquguqukayo kuyilapho egcina ukulula nokuqinile okuphezulu.

I-Cellulose, into engadliwayo, esekelwe ku-bio, inomthelela ekusimameni kwemvelo futhi ibonakala njengento engenayo i-carbon emunca i-CO2. Uma ibhangqwe ne-carbon steel (S45C), lawa mabanga amasha e-POM abonisa i-coefficient ephansi ye-dynamic friction kanye nokuguga okuncishisiwe, okuwenza alungele izinhlelo zokusebenza ezidinga kokubili ukuqina okuphezulu kanye nezakhiwo ezinhle kakhulu zokuslayida.

Singakuthuthukisa kanjani ukumelana nokugqokwa kwe-POM ngaphandle kokudela ukusebenza noma ukusimama?

Ukubhekana Nezinselelo Zokugqoka Nezingxabano ku-POM

Ngaphandle kwalokhu kuthuthuka, izinto eziningi ze-POM zisabhekene nezinselelo ezibalulekile ngokuguga nokungqubuzana, ikakhulukazi ezinhlelweni zokusebenza ezidingeka kakhulu njengezimoto, izinto zikagesi, nezimpahla zabathengi.

Okunye okuningiizindlela ezijwayelekile ezisetshenziselwa ukuthuthukisa ukumelana nokugqokwa kwe-POMzihlanganisa:

1. Izengezo ze-PTFE: I-Polytetrafluoroethylene (PTFE) inganciphisa kakhulu ukungqubuzana nokuguga ku-POM. Nokho, amanani eqile angenza buthaka amandla emishini, ngakho-ke umthamo olinganiselayo ubalulekile.

Ukwengeza, i-PTFE ingeyeqembu lezinto ezaziwa ngokuthi yi-per- kanye ne-polyfluoroalkyl substances (PFAS). Ngenxa yezingozi ezingaba khona zezempilo nezemvelo ezihlobene ne-PFAS, i-European Chemicals Agency ishicilele isiphakamiso esivela emazweni amahlanu angamalungu ukuze kuvinjelwe i-PFAS equkethe okungenani i-athomu yekhabhoni egcwele i-fluorified ngokugcwele - okulinganiselwa ukuthi ama-molecule ahlukene ayi-10,000, okuhlanganisa nama-fluoropolymer adumile. Amazwe angamalungu azovotela lokhu kuvinjelwa ngo-2025. Uma isiphakamiso sase-Europe sihlala singashintshiwe, Uma isiphakamiso siqhubeka ngaphandle kwezinguquko, singase siholele ekushintsheni okuphawulekayo ekusetshenzisweni kwama-fluoropolymer avamile afana ne-PTFE ne-PVDF, okusishukumisela ukuba sihlole ezinye izindlela eziphephile nezisombululo ezintsha.

2. Ama-Inorganic Lubricant: I-Molybdenum disulfide, i-boron nitride, nezinto ezifanayo ezingaphili zingakha ifilimu yokudlulisa endaweni ye-POM, inciphise ukungqubuzana futhi ithuthukise ukumelana nokugqokwa. Kodwa-ke, lezi zithasiselo kufanele zikhethwe ngokucophelela ukuze kugwenywe ukuphazamisa ukuzinza kokushisa kwe-POM.

Izixazululo Ezintsha Zokumelana Nokuqina Kwe-Superior Wear ku-POM

Kulabo abafuna ukuthuthukisa ukumelana nokugqokwa kwe-POM, i-SILIKE ihlinzeka ngohlu lwezithako ezikhethekile ze-eco-Friendly eziklanyelwe ukuthuthukisa ukuqina nokucubungula izakhiwo:

1. I-Silicone Masterbatch (Siloxane Masterbatch)I-LYSI-311: Lokhu kwakheka kwe-pelletized kuqukethe u-50% we-ultra-high molecular weight siloxane polymer, ehlakazwe ku-POM. Ithuthukisa izakhiwo zokucubungula kanye nekhwalithi ephezulu ye-POM, iyenze ibe isengezo sokuthuthukisa ukusebenza kwezinhlelo zokusebenza ezahlukahlukene.

 2. Isengezo se-Wear Resistance for POM compounds:Umndeni okhulayo ka-SILIKE wezithasiselo ze-silicone uthuthukisa kakhulu izakhiwo ezingaphezulu zezinhlanganisela ze-polyoxymethylene (POM).

Siyaziqhenya ukwethula ukwengeza kwethu kwakamuva emndenini wakwaizithasiselo ze-silicone,I-LYSI-701. Lesi sengezo se-silicone esisha senzelwe ngokukhethekile ukuthuthukisa ukumelana nokugqokwa kwezinhlanganisela ze-polyoxymethylene (POM). Ngesakhiwo sayo esiyingqayizivele se-poly-siloxane, i-LYSI-701 ihlakazeka ngokulinganayo kuyo yonke i-POM resin, yenze ngempumelelo isendlalelo sokuthambisa ngaphezulu. Lokhu kuthuthuka kunciphisa kakhulu i-coefficient of friction (CoF), kuyilapho futhi kuthuthukisa ukuhuzuka kanye nokumelana ne-mar. Ngenxa yalokhu, i-LYSI-701 inikela ekuqineni okuphelele nasekuphileni isikhathi eside kwezinto ze-POM, okuyenza ibe yisixazululo esibalulekile sezinhlelo zokusebenza ezahlukahlukene.

Izinzuzo Eziyinhloko zokusebenzisa leziizithasiselo ze-siliconezihlanganisa:

1. I-Friction Encishisiwe: Isakhiwo se-polysiloxane esiyingqayizivele sakha isendlalelo sokugcoba ku-POM, sehlisa ukungqubuzana nokuqinisa ukuguga kanye nokumelana ne-mar, kuyilapho sigcina izici ezinhle kakhulu zokusebenzisa.

2. Ikhwalithi Yobuhle Ethuthukisiwe: Iisithako se-siloxaneinika isiphetho esibushelelezi, ithuthukisa ukukhanga okubonakalayo kwemikhiqizo eqediwe.

3. Ukucubungula Okuthuthukisiwe: lokhuAnti-abrasion Masterbatchkuthuthukisa ukubumba nokukhulula izakhiwo, kukhuphule ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo.

4. I-Eco-friendly futhi Iphephile:izithasiselo ze-siliconeayinabo ubuthi, ayinaphunga, futhi ayihambisani nemvelo, iyahlangabezana nezindinganiso ze-ROHS kanye ne-REACH izimfuneko zokubhalisa ngaphambilini. 

Izicelo zezithasiselo ze-siloxane ku-High-Performance POM Components

LeziIzithasiselo zePlastiki nama-Polymer modifiersikakhulukazi i-LYSI-311 kanye ne-LYSI-701, zilungele izingxenye ze-POM ezisebenza kahle ezisetshenziswa ekukhiqizeni izicelo, njenge:

·Amagiya, ama-Bearings, nama-Conveyor Belts: Lapho ukumelana nokugqokwa nokuqina kubaluleke kakhulu.

·Izimoto: Kubandakanya amasistimu okuphakamisa amawindi nezinzwa zekholomu yokuqondisa.

·Izimpahla Zabathengi: Impahla yasendlini, okokusebenza kwezemidlalo, nezinye izinto ezidinga ukumelana nokugqokwa okuphezulu.

Ngokuhlanganisa lezi zithako ezisekelwe ku-silicone ekwakhiweni kwe-POM, abakhiqizi be-POM bangathuthukisa kakhulu izici zemishini nokuhlala isikhathi eside kwemikhiqizo yabo kuyilapho benciphisa ukungqubuzana, ukuguga, nomthelela wendawo.
