Qiimaha qashinka tungsten kaarbide ee Maraykanka ayaa hoos u dhacay heerkii ugu hooseeyay in ka badan toban sano iyada oo ay jirto hoos u dhac ku yimid qiimaha ammonium paratungstate (APT) iyo taariikh ahaan tiro aad u badan oo bikrad ah iyo alaabada qashinka tungsten carbide.

Hoos u dhaca qiimaha APT toddobaadyadii dhawaa waxay niyad jabinaysaa dib u soo celinta walxaha xoogga leh ee tungsten carbide qashinka iyada oo la siinayo agab quudin qiimo jaban oo loogu talagalay alaabta tungsten.

Suuqa qashinka kaarbiide-ka ee Mareykanka ayaa ka soo baxaya xilli jiil sare oo qashinka ah iyo iyadoo baahida loo qabo ay sii yaraaneyso qalabka karbide-ka. Korodhka weyn ee soo dejinta carbide waxay kortay alaabada gudaha, halka dhiirigelinta dhaqaale ee ka faa'iidaysiga alaabtan ay hoos u dhacayso.

Celceliska qiimaha dhoofinta bishiiba Shiinaha ee APT bishii Luulyo ayaa gaadhay heerarkii ugu hooseeyay muddo laba sano ah $197-207/mtu. Qiimaha ayaa hoos u dhacay 23pc celcelis ahaan qiimaha bishii ee $255-265/mtu ee Janaayo 2019.

Qiimaha iibka Processor-ka Mareykanka ee xirmooyinka qashinka tungsten carbide iyo wareegyada ayaa hoos ugu dhacay $5.00-6.00/lb bishii Agoosto laga bilaabo $7.25-8.25/lb bil ka hor. Hoos u dhaca 29pc ayaa calaamad u ah qiimaha ugu hooseeya ee wareegyada qashinka karbidhida iyo gelinta tan iyo dhamaadkii Janaayo 2009.

Processors ayaa sheegay in qashinka karbide aan dib loogu warshadayn APT tiro la mid ah sanadihii hore taas oo ay ugu wacan tahay baahida ka imanaysa macaamiisha gudaha iyo kuwa baddaba. Walxaha ka soo baxa qashinka carbide ee dib u iibinta. In kasta oo cadaadiska APT raqiis ah ka yimid, macaamiishu waxay ku doodayaan in dib-u-warshadaynta qashinka carbide aysan joojin doonin wax soo saarka si ay u iibsadaan APT beddelka qashinka sifaynta alaabta.
