Khoom nta thiab qhov zoo
Cov qauv txheej txheem tshwj xeeb, cov qauv tsim kho kom zoo, cov khoom siv tau zoo heev thermal poob siab, corrosion tsis kam, creep kuj thiab lwm yam khoom.
Kev siv lub tshuab nqus tsev kub nias sintering thoob ntiaj teb, cov khoom siv yog qhov muag heev, qhov ceev yog siab, thiab nws muaj lub cev zoo heev.
Nws tsis hnov mob hauv ntub lossis stain nrog molten hlau ntawm qhov kub thiab txias, thiab siv dav hauv ntau daim ntawv thov hauv kev sib cuag nrog cov hlau molten.
Boron Nitride Composite Ceramics Ntim thiab Thauj Khoom
Cov khoom ntim yog ua raws li "Technical Specifications" lossis cov qauv kev lag luam;
Lub ntim ntawm Boron Nitride Composite Ceramics ua tau raws li cov yam ntxwv thiab kev ua tau zoo ntawm cov khoom nws tus kheej, suav nrog txaus los tiv thaiv cov khoom los ntawm ya raws, nag, xeb, corrosion, thiab poob siab, thiab lwm yam, thiab tuaj yeem txais ntau yam tuav, thauj khoom thiab tshem tawm, thiab kev thauj mus los. ;
Cov txheej txheem tsim khoom thiab txheej txheem tsim khoom
Cov txheej txheem tsim khoom ntawm Boron Nitride Composite Ceramics suav nrog cov kauj ruam tseem ceeb xws li kev xaiv cov khoom siv raw, boron nitride hmoov npaj, molding, sintering kev kho mob, thiab tom qab ua tiav thiab kuaj. Txhua kauj ruam yuav tsum muaj kev tswj xyuas nruj ntawm cov txheej txheem tsis ua haujlwm thiab kev ua haujlwm kom ntseeg tau qhov zoo thiab kev ua haujlwm ntawm cov khoom kawg. Nrog rau kev nce qib ntawm cov thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm cov txheej txheem, cov txheej txheem tsim khoom ntawm Boron Nitride Composite Ceramics yuav txuas ntxiv txhim kho thiab ua kom tiav los muab cov ntaub ntawv zoo dua rau kev txhim kho ntawm ntau yam kev lag luam.
