Daaweynta biyaha wasakhda ah ee warshadaha, daabacaadda iyo rinjiyeynta biyaha wasakhda ah waa mid ka mid ah biyaha wasakhda ah ee ugu adag in la daweeyo. Waxay leedahay qaab-dhismeed adag, qiimo sare oo chroma ah, xoog badan, waana ay adag tahay in la burburiyo. Waa mid ka mid ah biyaha wasakhda ah ee warshadaha ugu daran uguna adag in la daweeyo ee wasakheeya deegaanka. Ka saarista chroma-ga ayaa ka sii adag dhibaatooyinka.
Hababka badan ee daaweynta biyaha wasakhda ah ee daabacaadda iyo rinjiyeynta, isticmaalka xinjirowga dhiigga ayaa ah habka ugu badan ee shirkadaha loo isticmaalo. Waqtigan xaadirka ah, xinjirowga dhiigga ee caadiga ah ee loo isticmaalo daabacaadda dharka iyo warshadaha rinjiyeynta ee dalkayga waa xinjirowga birta ku salaysan ee aluminiumka iyo xinjirowga birta ku salaysan. Saamaynta midabaynta waa mid liidata, haddii midabaynta falceliska ah la beddelo, ma jirto wax saameyn midabayn ah, waxaana weli jiri doona ion-yada birta ah ee biyaha la daweeyay, kuwaas oo weli aad u waxyeello u leh jirka aadanaha iyo deegaanka ku xeeran.
Wakiilka qurxinta resin-ka ee Dicyandiamide formaldehyde waa nooc ka mid ah polymer flocculant-ka dabiiciga ah, nooca cusbada ammonium-ka ee quaternary. Marka la barbardhigo flocculants-ka caadiga ah ee qurxinta midabka, waxay leedahay xawaare flocculation oo degdeg ah, qiyaas yar, waxaana saameeya milixda isku dhafan, PH iyo Faa'iidooyinka sida saameynta heerkulka oo yar.
Wakiilka qurxinta resin-ka ee dicyandiamide formaldehyde waa flocculant oo inta badan loo isticmaalo qurxinta midabka iyo ka saarista COD-ga. Marka la isticmaalayo, waxaa lagu talinayaa in qiimaha pH-ga ee biyaha wasakhda ah loo hagaajiyo si dhexdhexaad ah. Fadlan la xiriir farsamoyaqaannada si aad u hesho habab gaar ah oo loo isticmaalo. Sida laga soo xigtay iskaashi badan, jawaab celinta soo saarayaasha daabacaadda iyo rinjiyeynta resin-ka ayaa ah in decoration resin-ka dicyandiamide formaldehyde uu saameyn weyn ku leeyahay qurxinta midabka daabacaadda iyo rinjiyeynta biyaha wasakhda ah. Heerka ka saarista chroma wuxuu gaari karaa in ka badan 96%, heerka ka saarista COD-na wuxuu sidoo kale gaaray in ka badan 70%.
Daloollada polymer-ka ee dabiiciga ah ayaa markii ugu horreysay la isticmaalay sannadihii 1950-meeyadii, gaar ahaan daloollada daaweynta biyaha ee polyacrylamide, polyacrylamide-na waxaa loo qaybin karaa kuwa aan ionic ahayn, anionic, iyo cationic. Maqaalkan, waxaan ku fahmi doonnaa daloollada polymer-ka ee acrylamide ee dicyandiamide formaldehyde resin decolorizing flocculant kaas oo lagu cusbeeyo amine quaternary oo ka mid ah daloollada polymer-ka ee dabiiciga ah ee cationic.
Dareeraha dicyandiamide formaldehyde resin decolizing flocculant waxaa marka hore lagu falgalaa xalka biyaha ee acrylamide iyo formaldehyde marka xaalad alkaline ah jirto, ka dibna waxaa lagu falgalaa dimethylamine, ka dibna waxaa lagu qaboojiyaa oo lagu qasbaa hydrochloric acid. Badeecada waxaa lagu ururiyaa uumi-baxa waxaana la sifeeyaa si loo helo monomer acrylamide ah oo quternized ah.
Dareeraha isku-dhafka ah ee dicyandiamide-formaldehyde-ka ah ee polymer-ka ah ee decoration polymer-ka ayaa la soo bandhigay 1990-meeyadii. Waxay leedahay saameyn gaar ah oo aad u fiican oo ah ka saarista midabka biyaha wasakhda ah ee dheeha. Daaweynta biyaha wasakhda ah ee midabka sare leh iyo kuwa xoogga badan, waxaa la isticmaalaa oo keliya polyacrylamide ama polyacrylamide. Dareeraha polyaluminum chloride si buuxda uma saari karo midabka, ka dib marka lagu daro dareeraha midab-beddelka ah, waxay dhexdhexaadisaa lacagta taban ee ku xiran molecules-ka dheeha ee biyaha wasakhda ah iyadoo bixinaysa tiro badan oo cations ah sidaas darteedna way khalkhal gelisaa Ugu dambeyntii, tiro badan oo dareeraha ah ayaa la sameeyaa, kuwaas oo nuugi kara molecules-ka dheeha ka dib dareeraha iyo xasilloonida, si loo gaaro ujeeddada dareeraha.
Sida loo isticmaalo decolorizer:
Habka loo isticmaalo flocculant-ka midabaynta ayaa la mid ah kan polyacrylamide. In kasta oo kan hore uu yahay mid dareere ah, haddana waa in la qaso ka hor inta aan la isticmaalin. Soo-saaruhu wuxuu ku talinayaa in lagu qaso 10%-50%, ka dibna lagu daro biyaha qashinka ah oo si buuxda loo walaaqo. Samee ubaxyo alum ah. Walxaha midabka leh ee ku jira biyaha wasakhda ah ee midabka leh ayaa la isku shubaa oo laga soo saaraa biyaha, waxaana lagu qalabeeyaa wasakh ama sabbeyn hawo si loo gaaro kala-goyn.
Warshadaha daabacaadda iyo rinjiyeynta, dharka iyo warshadaha kale, isticmaalka biyuhu aad buu u badan yahay heerka dib-u-isticmaalkana waa hooseeyaa. Sidaa darteed, qashinka kheyraadka biyuhu aad buu u badan yahay. Haddii habka loo isticmaalo in lagu sameeyo daaweyn heer sare ah iyo dib-u-warshadayn biyaha wasakhda warshadaha ee midabka sare leh iyo kuwa aadka u badan, kaliya ma badbaadin karo kheyraad badan oo biyo warshadeed oo cusub, laakiin sidoo kale waxay si toos ah u yareyn kartaa daadinta biyaha wasakhda warshadaha, taas oo muhiimad weyn iyo mid ballaaran u leh kor u qaadista horumarka waara ee warshadaha daabacaadda, rinjiyeynta iyo dharka.
