Ngenxa yokunyuka kwexabiso le-tungsten carbide, into ebalulekileyo kwi-roller cone kunye nee-PDC bits, iindleko zemveliso zinyuke kakhulu. Amaxabiso ezinto eziluhlaza ayaqhubeka nokunyuka, nto leyo eyenza imeko ibe mandundu. Uluhlu lwethu luphantse lwaphela. Ukuze sijongane nale mingeni, siza kulungisa amaxabiso ee-bits zethu. Siyayixabisa indlela eniqonda ngayo njengoko sizama ukugcina umgangatho.
Ukunyuka kwamaxabiso e-tungsten carbide kutshanje kuvela kwizinto ezininzi ezidibeneyo. Imida yokubonelela iyalawula, njengoko iTshayina—evelisa i-82.7% ye-tungsten yehlabathi—ibeke ulawulo oluqinileyo lokuthumela ngaphandle kwiimveliso ze-tungsten ezingavuthwanga ezifana ne-ammonium paratungstate (APT) kunye ne-tungsten oxide ngoFebruwari 2025, inciphisa ukuthunyelwa kwamanye amazwe ngaphezulu kwe-80%. Kwangaxeshanye, iqela layo lokuqala lezabelo zemigodi ye-tungsten ka-2025 lehle nge-6.45% unyaka nonyaka, apho iPhondo laseJiangxi linciphisa imveliso nge-10%. Olu xinzelelo lwemigaqo-nkqubo lubini lushiye iimarike zehlabathi zixinezelekile, ngakumbi njengoko amazwe aseNtshona ezama ukutshintsha iimpahla zaseTshayina.
Uxinzelelo olukwicala lemfuno lubaluleke ngokulinganayo. Amacandelo amatsha amandla, kuquka iingcingo ze-tungsten ze-photovoltaic (ukungena okungaphezulu kwe-12%) kunye nee-reactors ze-nuclear fusion ezifuna iitoni ezingama-3,000 ze-tungsten, ziqhubele phambili ukusetyenziswa okungazange kubonwe ngaphambili. Imfuno yomkhosi nayo inyukile phakathi koxinzelelo lwezopolitiko, ngelixa ukuveliswa okuphezulu-njengezixhobo ze-carbide ezichanekileyo zee-EV kunye neerobhothi zoshishino-komeleza usetyenziso lwe-premium. Ukuqokelelwa kwezinto eziqikelelweyo ngababoneleli kwandisa ukunqongophala, kunye namaxabiso omgubo we-tungsten afikelela kwi-364 yuan/kg ngoJuni 2025. Nangona kukho ukulungiswa kwemarike kwexesha elifutshane, ukunqongophala kwexesha elide kunye nokugcinwa kwezicwangciso yi-EU kunye ne-US kubonisa ukuba kuqhubeke kunyukela phambili.
Ngenxa yezizathu zokunyuka kweendleko ze-tungsten carbide, ixabiso lee-drill bits lilungisiwe. Ukuba ubeka iodolo, nceda uqhagamshelane nexabiso lamva nje.
