Simbi billet zvinhu, mushure mekudhirowa chaiko, oxidation yemahara uye inopenya kupisa kurapwa (NBK nyika), isingaparadze kuyedza, yakanyanya-kudzvanywa kutsvaira uye kunhonga asidhi yemukati megomba resimbi pombi, anti rust mafuta kurapwa kwemukati nekunze madziro. yepombi yesimbi, uye kurapwa kwekudzivirira guruva kumativi ose evhavha.
1. Madziro emukati nekunze epombi yesimbi haana oxide layer;
2.Withstand high pressure, hapana kuvuza, high precision, high smoothness;
3. Cold kukotama pasina deformation, kuwedzera, flattening pasina makatsemuka;
4. The pamusoro ngura kudzivirira kurapwa.
