Nrog rau kev nce cov muaj koob npe ntawm cov hmoov av, nyob rau hauv xyoo tsis ntev los no, cov neeg tau siv ntau hom thiab siv cov khoom lag luam graphite hmoov. Hauv kev tsim cov khoom sib xyaw ntawm cov khoom siv sib xyaw, cov hmoov ua si ib qho tseem ceeb tshaj plaws, ntawm cov hmoov molding yog ib qho ntawm lawv. Moulding graphite hmoov feem ntau yog compounded nrog lwm cov ntaub ntawv los ua ntau yam kev tshwj xeeb ntawm cov khoom lag luam. Cov hauv qab no ua plaub kab graphite editor qhia dab tsi yog pwm graphite hmoov thiab nws cov siv tseem ceeb:
Graphite sealing cov khoom ua los ntawm moulded graphite hmoov muaj lub hom phiaj tshwj xeeb. Moulding graphite hmoov muaj cov zoo huv, lubricity, qhov kub siab kuj, hnav tsis kam thiab corrosion tsis kam. Raws li graphite tub rog, mouled graphite hmoov yog ntxiv rau cov ntaub qhwv phenolite, thiab cov khoom siv tau ua rau cov ntaub ntawv graphite sib xyaw. Graphite Composite Sealing cov khoom yog hnav-resistant, kub-resistant thiab hloov ua cua, thiab tuaj yeem siv rau kev siv kub-resistant kub-nias cov hmoov raws li cov neeg siv khoom xav tau raws li cov neeg siv khoom siv.
Tseem muaj ntau cov kev siv ntawm cov tshuaj tua cov hmoov hauv kev lag luam. Moulding graphite hmoov muaj ib me thermal expectansion coefficienty thiab qhov kub siab tiv thaiv. Nws tuaj yeem ua rau hauv qhov kub kub tiv taus graphite crucible rau melting cov khoom siv muaj nqis. Lubricating cov khoom ntawm cov tshuaj ntsuab graphite tuaj yeem ua rau hauv cov roj nplua nyeem, thiab nws kuj tseem tuaj yeem sib txuas nrog roj hmab thiab cov yas ua kom tau thov hauv cov hluav taws xob. Kev siv cov hmoov uas cov hmoov uas tuaj yeem txuas ntxiv nthuav tawm yav tom ntej.
