Kusetjentiswa kwetimboni kwe-sodium sulfide kufaka ekhatsi tindzaba letiyinkimbinkimbi kakhulu. Ema workshop ekudaya, tisebenti tisebenta ngetimphahla letimelana nemakhemikhali ngobe i- sodium sulfide ikhipha igesi lenebuthi ngesikhatsi sekushisa lokusetulu. Titjalo tekuhlanta emanti langcolile tivame kuyisebentisa kufaka tinsimbi letisindzako, lokudzinga kulawulwa lokucinile kwelizinga lekudla kanye nekuhlomisa emaphayiphi ekudla ngetintfo tekulwa ne crystallization. Etindzaweni tekugaya emaphepha, lapho khona isetjentiselwa kutsambisa ipulp yetigodvo, indzawo yekusebenta kumele igcinwe yomile, ngemamati langasheleli phansi kanye netimphawu tekwecwayisa letifana nekutsi “Akuvunyelwe Tinkomishi Temanti” letifakwe etindvongeni.

Kutfumela ngalokucondzile kusuka eThekwini laseQingdao, eThekwini laseTianjin, naseThekwini laseShanghai, ngekusebenta kahle kwe-sodium sulfide lefaka ekhatsi emachweba lamakhulu emhlabeni wonkhe. Chafata lapha kute utfole tinsita letisezingeni lelisetulu.
