Nzira yekugadzirisa sei dambudziko rekusvibiswa kukuru uye maitiro asina kugadzikana ekudhaya dhayi nhema yesarufa?
Sei mamwe makambani achishandisa huwandu hwakawanda hwenhema yesarufa, asi mhedzisiro yekushandisa haina kunaka. Kuti tigadzirise kusvibiswa kwakanyanya uye kusagadzikana kwekudhaya kwesarufa nhema mumaitiro echinyakare ekudhaya sarufa nhema, mushonga wekuderedza zvinhu D wakashandiswa semushonga wekuderedza zvinhu wesarufa nhema weBR wekupenda shinda dzedonje, uye mashandiro ekudhaya uye kuchena kwesodium yetsika yealkali zvakaenzaniswa. Mhedzisiro yehuwandu hwesarufa nhema BR, sodium hydroxide, mushonga wekuderedza zvinhu weD, uye tembiricha yekudhaya pahunhu hwekudhaya zvakaongororwa. Mhedzisiro yekuedza inoratidza kuti pasi pemamiriro ezvinhu ehuwandu hwe sulphur black BR 60 g/L, sodium hydroxide 20 g/L, composite reducing agent D 19 g/L, uye dyeing tembiricha 95 ℃, kudzika kweruvara rwuri pachena (K/S) kweshinda ndeye 46.88, sipo inosimba inosvika 4-5, dry rubbing fastness ndeye 4 uye wet rubbing fastness ndeye 2. Composite reducing agent D se reducing agent inoenzaniswa ne sodium sulfide yechinyakare, uye K/S kukosha kweshinda yakadhayiwa ne composite reducing agent D kuri nani pane ne alkali sulfide process. Reducing sulfur element mu dyeing solution inodzikiswa ne78.0%, uye chemical oxygen demand mu machine waste solution inodzikiswa ne76.4%.
Saka, kuitira kuvandudza mhedzisiro yekudhaya uye kuchengetedza mari mukushandisanhema yesarufakudhaya, tinofanira kuziva mashandisirwo ezvinhu zvakaoma zvinoderedza ngura, zvinhu zvinoderedza ngura zvisingakuvadzi nharaunda uye mashandisirwo enzira dzinogona kufonerwa chero nguva kuti tibvunze, tinogona kupa mabasa ari nani.
Kambani yedu inonyanya kugadzira Sulfur nhema, Sulfur nhema yemvura, Perennial export kuBangladesh. India, Pakistan, Egypt, neIran. Zvese zviripo uye mhando zvakagadzikana zvakanyanya. Chinonyanya kukosha ipurofiti yemutengo.
