27SiMn Alloy Ipayipi Lensimbi Elingenamthungo

Incazelo emfushane:

Amapayipi ensimbi angama-27SiMn asetshenziswa kakhulu ezimbonini zezimoto, zikaphethiloli, zamakhemikhali nezokuthutha.27Ipayipi lensimbi le-SiMn lijwayelekile futhi liyashiswa, futhi limbozwe nge-phosphate ngaphakathi nangaphandle.Leli payipi lensimbi lisetshenziswa kakhulu esimweni esicishiwe nesifuthekile ukwenza izingxenye ezishisayo zokugxiviza (izingxenye ze-hydraulic) ezidinga ukuqina okuphezulu nokumelana nokugqoka, kanye nezingxenye ezishisayo zokugxiviza ezidinga ukuqina okuphezulu nokumelana nokugqoka.

Ipayipi lensimbi elingenamthungo le-27SiMn linokuqina okuphezulu, ububanzi obubucayi bokuqina emanzini bungu-8 ~ 22mm, ukusebenziseka kahle, ukuguquguquka kwepulasitiki okubandayo okuphakathi kanye nokushisela;Ngaphezu kwalokho, ukuqina kwepayipi lensimbi akunciphisi kakhulu ngesikhathi sokwelashwa kokushisa, kodwa kunamandla aphezulu kakhulu nokumelana nokugqoka, ikakhulukazi ekucimeni kwamanzi.
