Silicon carbide sic bushing yog ib hom tshiab ntawm cov khoom siv high-tech thiab hnav-resistant hauv ntiaj teb. Nws tau ua los ntawm cov hmoov silicon carbide purity, high-purity high-temperature carbon dub thiab binders, los ntawm kev nchuav, blanking, sintering, thiab cov txheej txheem tshem tawm xuab zeb, ua los ntawm cov khoom sib xyaw ua ke siab hnav.
Tam sim no nws siv ua lub bushing hauv cov khoom siv tsuas, xws li tooj liab, kub, hlau ore, nickel ore thiab lwm yam hauv cov hlau tsis yog ferrous. Nws ua lub luag haujlwm ntawm kev tiv thaiv kev hnav siab, lub neej hnav yog ntau dua 10 npaug ntawm cov hlau bushings thiab alumina bushing.
1. Daim ntawv thov ntawm sic bushing hauv kev lag luam mining
Rau kev sau kuv li, cov hmoov av thiab cov khoom siv thauj khoom muaj kev hnav hnyav rau ntawm cov kav dej. Lub neej ua haujlwm ntawm cov kav dej xa khoom siv yav dhau los tsawg dua ib xyoos, thiab tam sim no xaiv silicon carbide bushings tuaj yeem ua rau lub neej ua haujlwm ntau dua 10 zaug.
2. Vim li cas cov ntaub ntawv silicon carbide thiaj siv dav hauv kev lag luam mining?
Vim yog qhov hnav tsis kam ntawm cov kav dej ceramic, hauv qab no yog kev sib piv ntawm kev hnav tsis kam ntawm cov kav dej ceramic thiab lwm yam khoom siv.
Kev sib piv ntawm kev hnav tsis kam ntawm silicon carbide bushings
