I-Polyoxymethylene (i-POM) iwuhlobo lwe-polymer eqondile ngaphandle kweketango laseceleni, elinokuminyana okuphezulu kanye nekristalu ephezulu, enezici ezinhle kakhulu ezihlanganisayo.Isici esivelele kakhulu sale nto i-modulus yayo ephezulu yokunwebeka, ubulukhuni obuphezulu kanye nokuqina.

I-POM iyipulasitiki ecwebezelayo ene-fluidity enhle esimweni esincibilikisiwe.I-viscosity yayo ebonakalayo ithinteka kakhulu izinga lokugunda.Kuyinto ebucayi be-shear,

Ngokusho kwezinhlaka zamakhemikhali ezihlukene zamaketanga wamangqamuzana, i-polyoxymethylene ingahlukaniswa ibe yi-homopolymerization kanye ne-copolymerization.I-homopolymer ine-high density, crystallinity namandla emishini, kuyilapho i-copolymer inokuqina okuhle kokushisa, ukuqhutshwa kokubumba kanye nokumelana ne-asidi ne-alkali.

Ukusetshenziswa kwe-POM

1. Igiya lokudlulisa elilula, umkhono womhlahlandlela, ithoyizi lezimoto, igiya lezinsimbi.

2. I-POM ifaneleka kakhulu ukukhiqiza amaphampu ezimoto, izingxenye ze-carburetor, amapayipi kawoyela, ama-valve kagesi, amabhere ayizinkulungwane eziyishumi aphezulu, amagiya ezimoto, ama-crank, izibambo, ideshibhodi, amadivaysi okuphakamisa amafasitela, ukushintshwa kukagesi, amabhande ebhande lokuphepha, njll. ezimotweni.Ukukhiqiza izingxenye ezingagugi njengomkhono we-shaft, igiya kanye nebhulokhi eshelelayo kungamandla e-POM eguquliwe.Lezi zingxenye zinokuguga okuncane ensimbi, zinciphisa inani lamafutha okugcoba, futhi zithuthukise impilo yesevisi yezingxenye.Ngakho-ke, bangashintsha kabanzi ithusi, i-zinc nezinye izinsimbi ukukhiqiza ama-bearings, amagiya, izinduku zokudonsa, njll.
