Cov nyhuv ntawm pore degree ntawm qhov zoo

Tungsten carbidepores feem ntau tshwm sim los ntawm impurities nyob rau hauv lub dawb paug thaiv ua ntej sintering.Vim qhov tsis sib xws ntawm cov pores hauv cov qauv, yuav tsum tau soj ntsuam ob peb lub teb ntxiv.Thaum kuaj pom, koj tuaj yeem soj ntsuam ib qho los ntawm ib qho (los ntawm ntug ntawm cov qauv ntu mus rau qhov chaw).Xaiv qhov pom pom ntau tshaj plaws nrog cov pores feem ntau piv nrog GB / T 3489-1983 porosity standard duab.GB / T3489-1983 pore degree daim duab muab faib ua 11 theem, thiab nws cov pores account rau 0.1%, 0.2%, 0.4%, 0.6%, 0.8%, 1.0%, 1.2%, 1.4%,

Tungstencarbide blockstom qab polishing cov qauv raug pom ntawm 100 zaus, thiab qhov loj dua los yog sib npaug li 25 μm.Lub qhov dub nrog cov duab tsis sib xws tab sis cov npoo ntshiab yog hu ua av.Nws yog cov hmoov av los yog lwm yam av ntawm cov neeg nyob rau hauv qhov sib tov ntawmtungsten carbidehmoov thiab cov txheej txheem sintering, thiab qhov shrinking qhov tshuav los ntawm shrinking tom qab sintering.Tag nrho ntev ntawm tag nrho cov av ntawm tus qauv polishing nto yog hu ua av.
