UziSebenzisa njani kwakhona izixhobo zeTungsten Carbide

I-Tungsten carbide ikwabizwa ngokuba yi-tungsten alloy, i-carbide enesamente, i-alloy eqinile, kunye nesinyithi esinzima. Izixhobo ze-tungsten carbide ziye zanda kakhulu kwishishini langoku ukusukela ngo-1920s. Ngokusingqongileyo, ukurisayikilisha kweemveliso ze-tungsten carbide kuvela okunokuthi kubangele iindleko kunye nokuchithwa kwamandla. Kunokubakho indlela yomzimba okanye indlela yekhemikhali. Indlela yomzimba ngokuqhelekileyo kukudiliza izixhobo ze-tungsten carbide ezichithiweyo zibe ziingcezu, okunzima ukuyiqonda kwaye ixabisa kakhulu ngenxa yobunzima obukhulu bezixhobo ze-tungsten carbide. Ke, ukuphinda kusetyenziselwe izixhobo zokusika i-tungsten carbide zihlala ziqondwa kwiindlela zeekhemikhali. Kwaye iindlela ezintathu zeekhemikhali ziya kuqaliswa---ukubuyisela i-zinc, ukubuyiswa kwe-electrolytic, kunye nokukhutshwa nge-oxidation.

Ukubuyiselwa kweZinc

IZinc luhlobo oluthile lwekhemikhali enenombolo ye-athomu engu-30, enamanqaku okunyibilika angama-419.5℃ kunye namanqaku abilayo angama-907℃. Kwinkqubo yokubuyisela i-zinc, izixhobo zokusika i-tungsten carbide zifakwe kwi-zinc etyhidiweyo phantsi kwendawo ye-650 ukuya kwi-800 ℃ kuqala. Le nkqubo yenzeka ngegesi engasebenziyo kwiziko lombane. Emva kokubuyiselwa kwe-zinc, i-zinc iyakuchithwa phantsi kobushushu obungama-700 ukuya kuma-950 ℃. Njengomphumo wokubuyisela i-zinc, i-powder efunyenweyo iphantse ifane ne-powder enyulu ngokulinganayo.

UkuBuyiswa kwe-Electrolytic

Kule nkqubo, i-cobalt binder inokuchithwa nge-electrolyzing scrap yezixhobo zokusika i-tungsten carbide ukubuyisela i-tungsten carbide. Ngokubuyiswa kwe-electrolytic, akuyi kubakho ukungcola kwi-tungsten carbide ebuyiselweyo.

Ukutsalwa nge-Oxidation

1. I-Tungsten carbide scrap kufuneka igaywe ngokuxutywa kunye ne-oxidizing agents ukuze ufumane i-sodium tungsten;

2. I-sodium tungsten inokunyangwa ngamanzi kunye namava okucoca kunye nemvula yokususa ukungcola ukufumana i-sodium tungsten ecocekileyo;

3. I-tungsten ye-sodium ecocekileyo inokuphendulwa nge-reagent, enokuthi ichithwe kwi-solvent ye-organic, ukufumana iintlobo ze-tungsten;

4. Yongeza isisombululo se-ammonia samanzi kwaye uphinde ukhuphe kwakhona, sinokufumana isisombululo se-ammonium poly-tungstate;

5. Kulula ukufumana i-ammonium para-tungstate crystal ngokukhupha isisombululo se-ammonium poly-tungstate;

6. I-ammonium para-tungstate ingabalwa kwaye iyancipha nge-hydrogen ukufumana isinyithi se-tungsten;

7. Emva kokungcwaba isinyithi se-tungsten, sinokufumana i-tungsten carbide, enokuthi yenziwe kwiimveliso ezahlukeneyo ze-tungsten carbide.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
