Kwizinto zanamhlanje zenzululwazi kunye nokuveliswa kwemizi-mveliso, i-tungsten kunye ne-alloys zayo zifunwa kakhulu ngemathiriyeli ngenxa yeempawu zazo ezizodwa. I-Tungsten, isinyithi esinqabileyo esinendawo yokunyibilika ephezulu kakhulu, ukuxinana okuphezulu, ubunzima obubalaseleyo kunye nokuhamba kombane okugqwesileyo, isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana ne-electronics, ukukhanya, i-aerospace, unyango kunye nomkhosi. Nangona kunjalo, kwiminyaka yakutshanje, siye sabona ukuba ixabiso le-tungsten liye laqhubeka linyuka, kwaye izizathu ezibangela oku zininzi, ezibandakanya inani lezinto ezifana nokutshintsha kwezinto eziguqukayo kwi-chain chain, ukukhula kwimfuno yezoshishino, kunye nokuguquguquka. kuqoqosho lwehlabathi.

Izithintelo zekhonkco lonikezelo
Eyona mithombo iphambili ye-tungsten igxile eTshayina, eRussia, eCanada nakwamanye amazwe, kwaye iTshayina ibalelwa kwisabelo esikhulu semithombo yetungsten yehlabathi. Le ngqwalasela yejografi yeempawu zemveliso yenza ukuba ikhonkco lonikezelo lwe-tungsten luchaphazeleke kakhulu kwimigaqo-nkqubo, imimiselo yokusingqongileyo, izithintelo zokuthumela ngaphandle kunye nezinye izinto. Kwiminyaka yakutshanje, ukuze kukhuselwe ubutyebi obunqabileyo kunye nokusingqongileyo, i-China kunye namanye amazwe amakhulu avelisayo abeke ulawulo olungqongqo kwimigodi ye-tungsten kunye nokulungiswa, okukhokelela ekuqinisweni kobonelelo lwe-tungsten yehlabathi kunye nokunyuka kwamaxabiso.

Ukukhula kwemfuno yemizi-mveliso
Ngophuhliso loqoqosho lwehlabathi, ngakumbi ukukhula okukhawulezayo kwamashishini aphezulu, imfuno ye-tungsten kunye ne-alloys yayo iyanda. Ukusuka kwimveliso yee-carbides ezinesamente kunye nokuveliswa kwezixhobo ze-aerospace kunye nezixhobo zasemkhosini ukuya kwimfuno yezixhobo zonyango kunye ne-elektroniki, i-tungsten iya isiba yinto eguquguqukayo kwaye imfuno iyaqhubeka ikhula. Oku kunyuka kwemfuno, ngakumbi xa unikezelo luthe gqolo, lukhokelela kumaxabiso aphezulu.

Utyalo-mali kunye nolindelo lwemarike
Njengemathiriyeli ekrwada yemizi-mveliso ebalulekileyo, i-tungsten iye yaba yinto ekugxilwe kuyo ingqalelo yabatyali-zimali. Ulindelo lweemarike lwamaxabiso e-tungsten, ukuziphatha okuqikelelwayo kwabatyali-mali, kunye nokuguquguquka kwiimarike zemali zonke zichaphazela ixabiso langempela le-tungsten. Kwezinye iimeko, ukulindela kweemarike zamaxabiso e-tungsten kwixesha elizayo kunokunyusa ukuguquguquka kwexabiso.

Impembelelo yokusingqongileyo koqoqosho lwehlabathi
Ukuguquguquka kuqoqosho lwehlabathi, njengotshintsho kumaxabiso otshintshiselwano kunye nohlengahlengiso kwimigaqo-nkqubo yorhwebo, kuya kuchaphazela neendleko kunye nexabiso le-tungsten. Uxinzelelo lwezorhwebo lwamazwe ngamazwe lunokukhokelela kwiindleko eziphezulu zokuthumela ngaphandle, nto leyo enokuthi ichaphazele amaxabiso e-tungsten. Ukongeza, ukucotha kokukhula koqoqosho lwehlabathi okanye ezinye izinto ze-macroeconomic nazo zinokuba nefuthe kwimfuno kunye nexabiso le-tungsten.

Ukuqukumbela
Ixabiso eliphezulu le-tungsten lisisiphumo sokudityaniswa kweempawu zayo ezizodwa ze-physicochemical, izithintelo zekhonkco lokubonelela, imfuno ekhulayo yemizi-mveliso, utyalo-mali lwemarike kunye nokusingqongileyo koqoqosho lwehlabathi. Njengoko imfuno yehlabathi ye-tungsten kunye ne-alloys yayo iqhubeka nokukhula, kunye nezixhobo ezinqongopheleyo, amaxabiso e-tungsten anokuhlala ephezulu kwikamva elibonakalayo. Nangona kunjalo, oku kubangele ishishini kunye nemibutho yophando ukuba igxininise ngakumbi ekusetyenzisweni kwakhona kwezixhobo ze-tungsten kunye nophando kunye nophuhliso lwezixhobo ezizezinye ukuhlangabezana nemingeni yexesha elizayo.
