Amaxabiso e-tungsten carbide scrap ase-US awele kwelona nqanaba lisezantsi kwisithuba esingaphezulu kweshumi leminyaka phakathi kokuhla kwamaxabiso e-ammonium paratungstate (APT) kunye nomthamo omkhulu ngokwembali we-inventory ye-tungsten carbide.

Ukwehla kwamaxabiso e-APT kwiiveki zamva nje kunciphisa ukuphinda kubuyiselwe izinto ezigxininisiweyo kwi-tungsten carbide scrap ngokubonelela ngexabiso eliphantsi lempahla yokutya kwimveliso ye-tungsten.

Imarike ye-carbide scrap yase-US iphuma kwixesha lokuveliswa kwe-scrap ephezulu kwaye ngelixa imfuno iyancipha izixhobo ze-carbide. Ukwanda okukhulu kokungeniswa kwekhabhide kumazwe angaphandle kukhulise uluhlu lwempahla yasekhaya, ngelixa inkuthazo yezoqoqosho yokusebenzisa ezi mveliso ihla.

Umyinge wamaxabiso athunyelwa ngenyanga ukusuka eChina kwi-APT ngoJulayi ufikelele kumanqanaba aphantsi kwiminyaka emibini kwi-197-207/mtu. Amaxabiso ehle nge-23pc ukusuka kwixabiso eliqhelekileyo lenyanga le-255-265/mtu ngoJanuwari ka-2019.

Iprosesa yase-US yokuthenga amaxabiso okufakwa kwe-tungsten carbide scrap kunye nemijikelezo yehla ukuya kwi-$ 5.00-6.00 / lb ngo-Agasti ukusuka kwi-$ 7.25-8.25 / lb ngenyanga ngaphambili. Ukuhla kwe-29pc kubonisa ixabiso eliphantsi le-carbide scrap rounds kunye nokufakwa ukususela ekupheleni kukaJanuwari 2009.

Abaprosesa bathi i-carbide scrap ayiphinda isetyenziswe kwi-APT kwimithamo efanayo kuneminyaka edlulileyo ngenxa yokungabikho kwemfuno evela kubathengi basekhaya nabangaphandle. izinto ezivela kwi-carbide scrap ukuze zithengiswe kwakhona. Ngaphandle koxinzelelo oluvela kwi-APT engabizi kakhulu, abathengi baphikisa ukuba i-carbide scrap recyclers ayiyi kumisa umveliso ukuthenga i-APT endaweni yokucoca i-scrap yezinto eziphathekayo.
