Izintengo ze-ferro tungsten ne-tungsten powder e-China zisesezingeni eliphansi ngokuqhathaniswa nomthelela we-coronavirus ekuqaleni kuka-Ephreli. Abathumeli bangaphandle be-Ammonium paratungstate (APT) bathole imakethe ehamba kancane, kuyilapho ukukhiqizwa kwe-downstream okungakatholakali, njengemboni yezimoto, e-China kuphinde kwehlise intengo yemakethe ye-tungsten yasekhaya.

Amakhasimende amaningi angaphandle akuhlehlise ukusayina izinkontileka zokuthenga ze-APT zesikhathi eside, mhlawumbe kuze kube sekupheleni kuka-April, futhi asebenzisa amasheya ukuze aqhubekisele phambili imisebenzi yawo yamanje. Isidingo esintengayo sabathengi baphesheya senze abakhiqizi babambe umbono oqaphile ekuthuthukisweni komnotho ngemuva kwegciwane kanye nesidingo semikhiqizo ekhuphuka nomfula.

Izinkampani zasekhaya manje zithembele ekutshalweni kwengqalasizinda entsha uhulumeni waseChina amemezele ukuthi kuzosheshisa. Esikhathini esifushane, abahlanganyeli bemakethe bazonaka izintengo ezintsha zomhlahlandlela ezivela ezikhungweni ze-tungsten nezinkampani ezisohlwini.
