I-Global - Premier Sodium Sulfide: Ikhemikhali Ebalulekileyo KwiiNdawo Ezihlukeneyo Zemizi-mveliso
IiNdawo eziPhambili zeSicelo
Kwishishini lephepha, i-sodium sulfide yethu idlala indima ebalulekileyo kwinkqubo yokukhupha i-kraft. Inceda ekuqhekekeni kwe-lignin, i-polymer eyinkimbinkimbi yendalo ebopha imicu ye-cellulose emthini. Ngokunyibilikisa i-lignin, i-sodium sulfide ivumela ukwahlulwa kwe-cellulose, eyona nto iphambili esetyenziselwa ukwenza iphepha. Oku kuphumela kwi-pulp esemgangathweni ophezulu enamandla aphuculweyo kunye nokukhanya. Abavelisi bephepha banokuvelisa uluhlu olubanzi lweemveliso zephepha, ukusuka kwi-newsprint ukuya kumaphepha okuprinta aphezulu, besebenzisa i-sodium sulfide yethu ukuphucula ukusebenza kakuhle kwemveliso yabo kunye nomgangatho wemveliso.
Ishishini lempahla likwazuza kakhulu kwiGlobal - Premier Sodium Sulfide yethu. Isetyenziswa kwinkqubo yokususa i-sulfurization yoboya. Uboya budla ngokuba neekhompawundi ezine-sulfur ezinokuchaphazela umgangatho kunye nokucutshungulwa kwabo. I-Sodium sulfide isabela kunye nezi khompawundi, isusa i-sulfur kwaye iphucule ukuthamba, umbala, kunye nomgangatho uphela woboya. Ukongeza, isetyenziswa kwezinye iinkqubo zokudaya ukulungisa imeko-bume yeekhemikhali, iququzelela ukufunxwa ngcono kwedayi yilaphu, okukhokelela kwimibala eqaqambileyo nehlala ixesha elide.
Kwishishini lezemigodi, i-sodium sulfide sisixhobo esibalulekileyo sokwenza izinto zibe mdaka. Isetyenziswa kwinkqubo yokuqubha kweentsimbi ezithile zesinyithi, ingakumbi ezo ziqulethe ubhedu, i-lead, kunye ne-zinc. I-sodium sulfide ingenza umphezulu wezi ntsimbi usebenze, nto leyo eyenza ukuba zamkele ngakumbi izinto eziqokelelwayo ezisetyenziswa ekuqubha. Oku kuphucula kakhulu ukusebenza kakuhle kokwahlula iiminerali ezixabisekileyo kwi-gangue (ilitye lenkunkuma), kwandisa izinga lokubuyiselwa kweentsimbi ezixabisekileyo. Iinkampani zezemigodi zixhomekeke kwi-sodium sulfide yethu ukuze ziphucule imisebenzi yazo yokucubungula i-ore kwaye zikhulise inzuzo yazo.
Kwishishini lesikhumba, i-sodium sulfide yethu isetyenziswa kwinkqubo yokususa uboya. Inceda ekunyibilikiseni iiproteni ezinweleni nakwi-epidermis yezikhumba zezilwanyana, okwenza kube lula ukususa iinwele. Eli linyathelo elibalulekileyo kwimveliso yesikhumba njengoko ilungiselela uboya ukuba buqhubeke nokucutshungulwa. Ngokusebenzisa i-sodium sulfide yethu ekumgangatho ophezulu, abavelisi besikhumba banokuvelisa ulusu olunomphezulu ogudileyo kunye nobume obungcono, oluhlangabezana nemigangatho ephezulu yemarike yesikhumba yehlabathi.
