Dhowr jiho oo muhiim ah oo horumarinta graphite ah oo la ballaariyay

Graphite-ka la ballaariyay waa walax dabacsan oo daloolsan oo laga sameeyay jajabyada garaafiga iyada oo loo marayo hababka isku-dhafka, dhaqidda biyaha, qalajinta iyo ballaarinta heerkulka sare. Graphite-ka la ballaariyay ayaa isla markiiba ballaarin kara 150 ~ 300 jeer mugga marka la kulmo heerkul sare, isagoo ka beddelaya jajab una beddelaya sida dirxiga oo kale, si qaab-dhismeedku u dabacsan yahay, daloolo badan yahay oo qaloocsan yahay, aagga dusha sare la weyneeyo, tamarta dusha sare la hagaajiyo, iyo xoogga nuugista ee garaafiga la ballaariyo. oo la isku daray, taas oo kordhisa jilicsanaantiisa, adkeysigiisa iyo dabacsanaantiisa. Tifaftiraha soo socda ayaa kuu sharxi doona dhowr tilmaamood oo muhiim ah oo ku saabsan garaafiga la ballaariyay:

1. Graphite-ka la ballaariyay ee Granular: Graphite-ka yar ee la ballaariyay ee granular-ka ah wuxuu inta badan ka dhigan yahay graphite-ka la ballaarin karo ee 300 mesh, mugga ballaarintiisuna waa 100ml/g. Badeecadan waxaa inta badan loo isticmaalaa dahaarka dab-damiska, baahideeduna aad bay u badan tahay.

2. Graphite la ballaariyay oo leh heerkul sare oo ballaarin bilow ah: heerkulka ballaarinta bilowga ah waa 290-300 ° C, mugga ballaarintana waa ≥ 230 ml/g. Noocan garaafitka la ballaariyay waxaa inta badan loo isticmaalaa qalabka ka hortagga ololka ee balaastikada injineernimada iyo cinjirka.

3. Heerkulka ballaarinta bilowga ah oo hooseeya iyo garaafitka oo heerkulkiisu hooseeyo: heerkulka uu nooca garaafitka ee la ballaariyay uu ku bilaabmayo inuu ballaarto waa 80-150°C, mugga ballaarintuna wuxuu gaarayaa 250ml/g 600°C.

Soosaarayaasha graphite ee la ballaariyay waxay farsamayn karaan graphite-ka la ballaariyay una rogi karaan graphite dabacsan si loogu isticmaalo agab shaabadaysan. Marka la barbardhigo agabka shaabadaysan ee dhaqameed, graphite-ka dabacsan wuxuu leeyahay heerkul ballaaran oo la isticmaali karo, oo u dhexeeya -200°C ilaa 450°C hawada, wuxuuna leeyahay isku-darka ballaarinta kulaylka yar. Waxaa si weyn loogu isticmaalay batroolka kiimikada, mishiinnada, birta, tamarta atomiga iyo warshadaha kale.
