Yintoni iCaustic Soda Liquid?
Ulwelo lwesoda oluyiCaustic luyisisombululo samanzi se-sodium hydroxide (NaOH), esihlala sinikezelwa kumanqanaba angama-32% (udidi lwe-membrane, olusetyenziswa ekucoceni amanzi) okanye ama-46–50% (udidi oluqhelekileyo lwemizi-mveliso). Lususa inyathelo lokunyibilika elifunekayo ngeefom eziqinileyo kwaye luhlanganiswe ngokuthe ngqo kwiinkqubo zokulinganisa eziqhubekayo ngeempompo kunye neemitha zokuhamba. Njengenye yeekhemikhali zolwelo ezinomthamo ophezulu ezithunyelwayo, lunikezelwa yiTerracore Chemicals kwiikhonteyina ze-IBC, iilori zeetanki ezinkulu, okanye ii-isotainers kuxhomekeke kwindawo yomthengi kunye nomthamo.
Umlinganiselo weNkqubo eQhubekekayo
Isoda eyomileyo eyomileyo yeyona ikhethwayo apho kutyiwa khona umthamo omkhulu noqhubekayo weNaOH kwaye ukunyibilika okuqinileyo kuya kudala ingxaki. Iifektri zephepha ezithatha idosi yotywala obumhlophe, izityalo ze-chlor-alkali, izibonelelo zonyango lwamanzi, iindawo zelaphu ze-mercerising, kunye nee-reactor ezinkulu zeekhemikhali zonke zisebenza nge-caustic yolwelo enikezelwa kwiitanki zokugcina izinto ezityalwa ngqo yipompo. Ukuphepha ulawulo lobushushu bokunyibilika kunye nokukwazi ukulinganisa ngokuchanekileyo ngeepompo zokulinganisa iikhemikhali kwenza i-caustic yolwelo ibe yeyona ndlela isebenzayo yokusebenza kwizicelo eziphezulu.
Amashishini ePulp & Paper kunye neLaphu
Kwinkqubo ye-kraft pulp, i-caustic soda engamanzi yinxalenye ephambili yotywala obumhlophe kunye ne-sodium sulfide, esetyenziselwa ukupheka iitships zomthi kunye nokunyibilikisa i-lignin kwi-digester. I-make-up caustic yongezwa rhoqo ukuhlawula ilahleko zeekhemikhali kumjikelo we-pulping. Kwi-mercerisation yelaphu, isisombululo se-NaOH kwi-concentration ye-18-25% (i-mercerising lye) sisetyenziswa kwi-cotton warn okanye kwilaphu eliphantsi koxinzelelo ukuze kuvuvuke iifayibha, kuphuculwe i-dye affinity, amandla okutsalwa, kunye nokukhazimla - inkqubo eqhubekayo ekugqityweni kwelaphu elilukiweyo nelilukiweyo.
Unyango lwamanzi kunye nezicelo zokusingqongileyo
Amagunya amanzi kamasipala asebenzisa i-32% yesoda eyomileyo (umgangatho we-membrane) ukulungisa i-pH yamanzi okusela acociweyo ukulawula ukugqwala kwiinethiwekhi zokusasazwa. Izityalo zonyango lwenkunkuma yemizi-mveliso zithatha i-NaOH yolwelo ukuze zithomalalise ii-asidi kwaye zibangele iintsimbi ezinzima ngaphambi kokuba zikhutshwe. Kwiinkqubo zokuhlafuna igesi engcolileyo, i-caustic yolwelo isetyenziselwa ukufunxa i-SO₂ kunye ne-HCl kwiigesi ezivuthayo kwizityalo zeekhemikhali, kwiindawo zokutshisa, nakwizikhululo zamandla. I-Terracore inikezela nge-caustic yolwelo ngamaxwebhu okuhambisa, i-MSDS, kunye neSatifikethi soHlalutyo kuyo yonke impahla ethunyelweyo.
