URecycle Tungsten Carbide

I-Tungsten carbide (WC) yikhemikhali i-binary compound ye-tungsten kunye nekhabhoni kwi-stoichiometric ratio ye-93.87% ye-tungsten kunye ne-6.13% yekhabhoni. Nangona kunjalo, kwishishini eli gama lihlala lithetha i-tungsten carbides; imveliso yesinyithi enyibilikisiweyo ephothiweyo equka iinkozo ezicolekileyo kakhulu zetungsten carbide ecocekileyo ebotshelelwe okanye edityaniswe kunye kwimatrix yecobalt. Ubungakanani beenkozo ze-tungsten carbide ukusuka kwi-½ ukuya kwi-10 microns. Umxholo we-cobalt unokuhluka ukusuka kwi-3 ukuya kwi-30%, kodwa ngokuqhelekileyo uya kuvela kwi-5 ukuya kwi-14%. Ubungakanani bengqolowa kunye nomxholo we-cobalt unquma ukusetyenziswa okanye ukuphela kokusetyenziswa kwemveliso egqityiweyo.

I-carbide enesamente yenye yezona zimbiwa zexabiso, iimveliso ze-tungsten ze-carbide zisetyenziselwa ukwenza izixhobo zokusika kunye nokwenza izixhobo, u-drill, i-abrasives, i-rock bits, i-dies, i-rolls, i-ordnance kunye nokunxiba izixhobo ezingaphezulu. I-tungsten carbide idlala indima ebalulekileyo kuphuhliso lweshishini. Sonke siyazi ukuba i-tungsten luhlobo lwezinto ezingenakuhlaziyeka. Ezi mpawu zenza i-tungsten carbide scrap ibe yenye yezona zinto zikhuphisanayo zokuphinda zisetyenziswe.

Indlela yokuphinda usebenzise i-tungsten kwi-tungsten carbide? Kukho iindlela ezintathu eTshayina.

Okwangoku, zininzi iintlobo ezintathu ze-carbide esetyenzisiweyo kunye neenkqubo zokuhlaziya ezisetyenziswa ngokuqhelekileyo kwihlabathi, yindlela yokunyibilika kwe-zinc, indlela yokuchithwa kwe-electro-dissolution, kunye ne-mechanical pulverization method.

1. Indlela yokunyibilikisa iZinc:

Indlela yokunyibilikisa i-zinc kukongeza i-zinc kwiqondo lobushushu le-900 °C ukwenza i-zinc-cobalt alloy phakathi kwe-cobalt kunye ne-zinc kwinkunkuma ye-carbide enesamente. Kubushushu obuthile, i-zinc isuswa nge-vacuum distillation ukuze yenze ibloko ye-alloy efana ne-sponge ize icunyuzwe, idityaniswe, igaywe ibe ngumgubo okrwada. Ekugqibeleni, iimveliso ze-carbide ze-cemented zilungiswa ngokwenkqubo yesiqhelo. Nangona kunjalo, le ndlela inotyalo-mali olukhulu lwezixhobo, iindleko eziphezulu zemveliso, kunye nokusetyenziswa kwamandla, kwaye kunzima ukususa ngokupheleleyo i-zinc, okubangela umgangatho wemveliso ongazinzanga (ukusebenza). Ukongeza, i-zinc esetyenzisiweyo ye-disperant iyingozi kumzimba womntu. Kukwakho nengxaki yokungcoliseka kwendalo kusetyenziswa le ndlela.

2. Indlela yokuphelisa:

Indlela yokuchithwa kwe-electro-dissolution kukusebenzisa i-agent ye-leaching efanelekileyo ukunyibilikisa i-cobalt yensimbi ye-binder kwi-carbide ene-cemented inkunkuma kwisisombululo se-leaching phantsi kwesenzo sentsimi yombane kwaye emva koko i-chemically process ibe yi-cobalt powder, eya kuthi ichithwe. Iibhloko ze-alloy ezilahliweyo ze-binder ziyacocwa.

Emva kokutyumza kunye nokugaya, i-tungsten carbide powder ifunyenwe, kwaye ekugqibeleni, imveliso entsha ye-carbide eyenziwe ngesamente yenziwe ngokwenkqubo eqhelekileyo. Nangona le ndlela ineempawu zomgangatho omhle wepowder kunye nomxholo ophantsi wokungcola, ineengxaki zokuhamba kwexesha elide, izixhobo ze-electrolysis eziyinkimbinkimbi, kunye nokucutshungulwa kwe-tungsten-cobalt inkunkuma ene-cemented carbide enomxholo we-cobalt omkhulu kune-8%.

3. Indlela yokutyumza yoomatshini yemveli:

Indlela yemveli yokucoca ngoomatshini yindibaniselwano ye-manual kunye ne-mechanical pulverization, kunye ne-carbide ene-cemented cemented egalelwe ngesandla ifakwe eludongeni lwangaphakathi kunye ne-cemented carbide lining plate kunye ne-crusher exhotyiswe ngeebhola ze-carbide ezinobungakanani obukhulu. Ityunyuzwa ibe ngumgubo ngokuqengqeleka kunye (i-rolling) impembelelo, kwaye emva koko i-wet-ground ibe ngumxube, kwaye ekugqibeleni yenziwe kwiimveliso ze-carbide ezenziwe ngesamente ngokwenkqubo yesiqhelo. Olu hlobo lwendlela luchazwe kwinqaku elithi "Ukuhlaziya, ukuHlaziya, kunye nokuSetyenziswa kweNkunkuma eneCemented Carbide". Nangona le ndlela ineenzuzo zenkqubo emfutshane kunye nokutyalomali oluncinci lwezixhobo, kulula ukuxuba ezinye izinto ezingcolileyo kwizinto eziphathekayo, kunye nomxholo we-oksijini wezinto ezixubeneyo eziphezulu, ezichaphazela kakhulu umgangatho weemveliso ze-alloy, kwaye ayikwazi ukuhlangabezana neemfuno zemigangatho yemveliso, kwaye ibisoloko injalo Ukongeza, ukusebenza kakuhle kokutyumza kuphantsi kakhulu, kwaye ngokuqhelekileyo kuthatha malunga neeyure ezingama-500 zokuqengqeleka nokugaya, kwaye kudla ngokuba nzima ukufezekisa ukucoleka okufunekayo. Ngoko ke, indlela yonyango yokuvuselela ayizange idume kwaye isetyenziswe.

Ukuba ufuna ukufunda ngakumbi malunga nokuqhushumba kwe-abrasive, wamkelekile ukuba uqhagamshelane nathi ngolwazi oluthe vetsheion.
