Polyoxymethylene (POM) imhando yemutsara wepolymer isina padivi cheni, ine hupamhi hwepamusoro uye yakakwirira crystallinity, ine yakanakisa kunzwisisika zvivakwa.Chinonyanya kukosha chechinhu ichi ndechekukwira kwayo elastic modulus, kuoma kwakanyanya uye kusimba.
POM ipurasitiki yekristaro ine mvura yakanaka mumhepo yakanyungudutswa.Kuonekwa kwayo kunoratidzika kunonyanya kukanganiswa neshear rate.Icho chinhu chinocheka shear,
Zvinoenderana neakasiyana makemikari zvimiro zvemamorekuru cheni, polyoxymethylene inogona kukamurwa kuita homopolymerization uye copolymerization.Iyo homopolymer ine yakakwira density, crystallinity uye mechanical simba, nepo copolymer ine yakanaka yekudziya kugadzikana, kuumba processability uye asidhi uye alkaline kuramba.
Kushandisa POM
1. Nyore yekufambisa giya, kutungamira sleeve, toy mota giya, giya rekushandisa.
2. POM yakanyatsokodzera pakugadzira mapombi emotokari, zvikamu zve carburetor, pombi dzemafuta, mavharuvhu emagetsi, epamusoro pezviuru gumi mabheya, magiya emota, cranks, zvibato, dashboard, zvigadziriso zvekusimudza mahwindo, ma switch emagetsi, mabhandi ebhandi rekuchengetedza, nezvimwewo zvemotokari.Kugadzira zvipfeko zvinodzivirira kupfeka senge shaft sleeve, giya uye sliding block isimba reakagadziridzwa POM.Izvi zvikamu zvine kushomeka kwesimbi, kuderedza huwandu hwemafuta ekuzora, uye kuwedzera hupenyu hwebasa rezvikamu.Naizvozvo, ivo vanogona kutsiva zvakanyanya mhangura, zingi uye mamwe simbi kugadzira mabhengi, magiya, kudhonza tsvimbo, nezvimwe.
