Kufotokozera Kwachidule:

CRM imagwiritsidwa ntchito poyang'anira khalidwe ndi kuwongolera zida zowunikira powunika ferrosilicon.Amagwiritsidwanso ntchito poyesa ndi kutsimikizira kulondola kwa njira zowunikira.CRM ingagwiritsidwe ntchito kusamutsa mtengo woyezedwa.

Kulongedza ndi Kusunga

Zolemba zotsimikizika zimayikidwa m'mabotolo agalasi okhala ndi zovundikira zapulasitiki.Kulemera kwa Net ndi 50 g aliyense.Zimalangizidwa kuti zisunge zowuma zikasungidwa.
