ʻO ka hoʻohana ʻana i ka sodium sulfide ma ka ʻoihana e pili ana i nā hiʻohiʻona paʻakikī. Ma nā hale hana hoʻoluʻu, hana nā limahana i nā lole pale kemika no ka mea hoʻokuʻu ka sodium sulfide i nā kinoea ʻawahia i nā mahana kiʻekiʻe. Hoʻohana pinepine nā hale hana mālama wai ʻino iā ia e hoʻoheheʻe i nā metala kaumaha, e koi ana i ka kaohi paʻa o ka nui o ka hānai ʻana a me ka hoʻolako ʻana i nā paipu hānai me nā mea anti-crystallization. Ma nā hale wili pepa, kahi e hoʻohana ʻia ai e palupalu i ka pulp lāʻau, pono e mālama ʻia kahi hana i maloʻo, me nā moena anti-slip ma ka papahele a me nā hōʻailona hoʻomaopopo e like me "ʻAʻole ʻae ʻia nā kīʻaha wai" i kau ʻia ma nā paia.

Hoʻouna pololei ʻia mai ke awa ʻo Qingdao, ke awa ʻo Tianjin, a me ke awa ʻo Shanghai, me ka logistics kūpono o ka sodium sulfide e uhi ana i nā awa nui o ka honua holoʻokoʻa. Kaomi ma aneʻi e kiʻi i nā lawelawe kiʻekiʻe.
