Ukusetjenziswa kwe-sodium sulfide emabubulweni kufaka hlangana ubujamo obuyinkimbinkimbi. Ema-workshop wedayi, abasebenzi basebenza ngeengubo ezijamelana namakhemikhali ngombana i-sodium sulfide ikhupha amagesi anobuthi emazingeni womtjhiso aphezulu. Iintjalo zokuhlwengisa amanzi asilapheleko zivamise ukuyisebenzisa ukukhipha iinsimbi ezisindako, okutlhoga ukulawulwa okuqinileko kwezinga lokuphakela nokuhlomisa amapayipi wokuphakela ngamadivayisi wokulwisana nokukhiqiza amakristalu. Eendaweni zokugaya amaphepha, lapho isetjenziselwa ukuthambisa i-pulp yeplanka, indawo yokusebenza kufanele igcinwe yomile, ibe namamethi wokuvikela ukutjhelela phasi kanye namatshwayo wesiyeleliso afana nokuthi “Akuvunyelwa Iinkomitjhana zamanzi” afakwe emabodeni.

Ukuthunyelwa okunqophileko ukusuka e-Qingdao Port, e-Tianjin Port, kanye ne-Shanghai Port, ngokusebenza kuhle kwe-sodium sulfide ehlanganisa amachweba amakhulu ephasini loke. Tlika lapha ukuthola imisebenzi esezingeni eliphezulu.
