27SiMn Alloy Umbhobho wentsimbi ongenamthungo

27SiMn Ingxubevange yombhobho wentsimbi ongenamthungo oFakelweyo

Inkcazelo emfutshane:

Iipayipi zensimbi ze-27SiMn zisetyenziswa kakhulu kwiimoto, i-petroleum, iikhemikhali kunye namashishini okuthutha.27IsiMn umbhobho wentsimbi uqhelekile kwaye ushushu, kwaye uqatywe ngephosphate ngaphakathi nangaphandle.Lo mbhobho wentsimbi usetyenziswa ikakhulu kwimeko ecinyiweyo kunye nenomsindo ukwenza iindawo ezishushu zokutsibela (iindawo zehydraulic) ezifuna ubunzima obuphezulu kunye nokumelana nokunxiba, kunye neendawo ezishushu zokutsibela ezifuna ubunzima obuphezulu kunye nokumelana nokunxiba.

I-27SiMn umbhobho wentsimbi ongenamthungo unokuqina okuphezulu, ukuqina okubalulekileyo kwedayamitha emanzini yi-8 ~ 22mm, ukucwangciswa kakuhle, ukuguqulwa kweplastiki epholileyo ephakathi kunye ne-weldability;Ukongeza, ukuqina kombhobho wentsimbi akuncitshiswanga kakhulu ngexesha lonyango lobushushu, kodwa unamandla aphezulu kunye nokumelana nokunxiba, ngakumbi ekucimeni kwamanzi.
