Qhov zoo ntawm Graphite Rods tshaj Impregnated Graphite
Dec 13, 2022
Nias graphite raj thiab graphite rods yog raws li kev sib xyaw graphite hmoov (ntshiab ntuj graphite los yog hluavtaws graphite) thiab ntau yam binders nyob rau hauv ib qho kev faib ua feem, thiab tom qab ntawd ua ntej molding, nias (kub extrusion los yog txias forming) los yog high-temperature tshav kub kho khoom siv tes ua. . Txoj kev no tuaj yeem siv los tsim cov kav dej, daim hlau, cov kav dej, lub qhov rooj, lub twj tso kua mis, thiab lwm yam, thiab tseem tuaj yeem siv los ua cov hlau sib xyaw, couplings, mechanical sealing rings, cylinder pistons, thiab lwm yam. Piv nrog impregnated graphite, nws muaj cov hauv qab no. yam ntxwv:
1. Txoj kev tsim khoom yog qhov yooj yim, thiab cov khoom siv raw tuaj yeem ua los ntawm crushed graphite los tsim cov khoom graphite los tswj tus nqi.
2. Lub porosity yog me me, cov qauv txheej txheem yog ib yam, thiab cov dej permeability zoo.
3. Tom qab kev sib sau, cov duab yog qhov tseem ceeb thiab ci, thiab tsis muaj kev ua yog tias yuav tsum muaj tshwj tsis yog rau kev sib txuas xaus.
4. Lub tshav kub hloov coefficient yog me dua li ntawm impregnated graphite, thiab thermal expansion coefficient yog loj heev.
5. Nws muaj tshuaj lom neeg kev ntseeg tau zoo heev, hloov hluav taws xob, hluav taws xob conductivity, kub tsis kam, kub tsis kam thiab siab cuam tshuam toughness.
Tam sim no, ntau yam resin graphite siab raj, 300 degree nruab nrab kub kho graphite siab hlab thiab epoxy impregnated impregnated graphite hlab yog tag nrho cov siab hom impermeable graphite hlab.
