Cov txiaj ntsig ntawm cov ntawv graphite uas yoog tau ua cov khoom siv sib khi yog dab tsi?
Daim ntawv graphiteTam sim no siv ntau dua thiab ntau dua hauv kev lag luam hluav taws xob high-tech. Nrog rau kev txhim kho ntawm kev ua lag luam, daim ntawv graphite tau pom cov ntawv thov tshiab, ib yam lidaim ntawv graphite uas yoog tausiv tau ua cov ntaub ntawv kaw. Yog li ntawd, cov txiaj ntsig ntawm cov ntawv graphite uas yoog tau ua cov ntaub ntawv kaw yog dab tsi? Peb yuav muab kev tshuaj xyuas kom ntxaws rau koj:
Tam sim no, cov khoom siv graphite yooj ywm feem ntau suav nrog lub nplhaib ntim khoom,gasket, kev ntim khoom dav dav, cov phaj sib xyaw ua ke punched los ntawm cov phaj hlau, ntau yam gaskets ua los ntawm laminated (bonded) composite phaj, thiab lwm yam lawv tau siv dav hauv petrochemical, machinery, metallurgy, atomic zog, hluav taws xob thiab lwm yam haujlwm, nrog kev tiv thaiv corrosion zoo heev, kub kub tsis kam, shrinkage thiab rov qab zoo heev kev ntxhov siab mos siab muag thiab tus kheej lubricating zog.
Cov ntaub ntawv kaw ib txwm muaj feem ntau yog ua los ntawm asbestos, roj hmab, cellulose thiab lawv cov khoom sib xyaw. Txawm li cas los xij, nrog kev txhim kho ntawm kev lag luam, daim ntawv graphite yooj ywm ua cov ntaub ntawv kaw tau pib siv dav. Qhov ntsuas kub ntawm daim ntawv graphite yooj ywm muaj ntau, uas tuaj yeem ncav cuag 200 ~ 450 ℃ hauv huab cua thiab 3000 ℃ hauv lub tshuab nqus tsev lossis txo huab cua, thiab cov coefficient ntawm thermal nthuav dav yog me me. Nws tsis brittleness thiab tawg ntawm qhov kub qis thiab mos ntawm qhov kub siab. Cov no yog cov xwm txheej uas cov ntaub ntawv kaw ib txwm muaj tsis muaj. Yog li ntawd, daim ntawv graphite yooj ywm yog piav qhia tias yog "sealing king".
