Cov Khoom Paub meej
Nqe lus piav qhia: Saj zawg zog graphite ntawv yog tsim nrog ntshiab nthuav graphite. "Sungraf" hom saj zawg zog graphite ntawv muaj siab purity ntawm 99% cov ntsiab lus carbon
Qhov zoo
Cov tshuaj tiv thaiv zoo dua, zoo dua thermal conductivity, thiab zoo sealability.
Kev siv
- 01 Raws li cov khoom siv gasket, nws feem ntau yog tsim rau hauv Graphite Laminate, cov ntaub ntawv graphite ntxiv
- 02 dav siv nyob rau hauv cov kua sealing daim ntaub ntawv: flange gasket, kauv qhov txhab gasket, tshav kub exchanger gasket, thiab lwm yam.
- 03 Nws kuj tseem tuaj yeem siv los ua cov roj nplua nyeem hauv cov hlau stamping thiab tsim cov ntawv thov, lossis ua cov cua sov hauv cov cua sov hauv kev lag luam thiab lwm yam khoom siv cua sov.
