Ukwakheka Kwamakhemikhali
I-Q275 steel plate iwuhlobo lwensimbi yesakhiwo sekhabhoni, amandla aphezulu, ipulasitiki enhle nokusebenza kahle kokusika, ukusebenza kahle kokushisela, izingxenye ezincane zingacinywa futhi ziqiniswe, ikakhulukazi ezisetshenziselwa ukwenza izingxenye ezinezidingo eziphezulu, njengamagiya namashafti. , ama-sprockets, okhiye, amabhawodi, amantongomane, izinsimbi zesigaba semishini yezolimo, amaketanga okuthutha kanye nezixhumanisi.
