Dicyandiamide formaldehyde resin decoloring agent

Mu gutunganya amazi y’inganda mu nganda, gucapa no gusiga irangi amazi y’amazi ni kimwe mu bigoye gutunganya amazi y’amazi.Ifite ibice bigoye, chroma ndende, agaciro gakomeye, kandi biragoye kuyitesha agaciro.Nimwe mubikomeye kandi bigoye gutunganya amazi mabi yinganda yangiza ibidukikije.Gukuraho chroma biragoye cyane mubibazo.

Muburyo bwinshi bwo gucapa no gusiga amarangi uburyo bwo gutunganya amazi mabi, gukoresha coagulation nuburyo bukoreshwa cyane mubigo.Kugeza ubu, flocculants isanzwe ikoreshwa mu bucuruzi bwo gucapa no gusiga amarangi mu gihugu cyanjye ni aluminiyumu kandi ishingiye ku byuma.Ingaruka ya decolorisation ni mibi, kandi niba irangi ryirangi ryarimbishijwe amabara, nta nkurikizi ihari, kandi hazakomeza kubaho ioni yicyuma mumazi yatunganijwe, aracyangiza cyane umubiri wumuntu nibidukikije.

Dicyandiamide formaldehyde resin decoloring agent ni organic organic polymer flocculant, ubwoko bwumunyu wa kane.Ugereranije na gakondo isanzwe ya decolorizing flocculants, ifite umuvuduko wihuta wa flocculation, dosiye nkeya, kandi ihindurwa numunyu ubana, PH hamwe nibyiza nko kutagira ubushyuhe buke.

Dicyandiamide formaldehyde resin decoloring agent ni flocculant ikoreshwa cyane muri decolorisation no gukuraho COD.Iyo uyikoresheje, birasabwa guhindura pH agaciro k'amazi mabi atabogamye.Nyamuneka vugana nabatekinisiye kuburyo bwihariye bwo gukoresha.Dukurikije ubufatanye bwinshi Igitekerezo kiva mu icapiro no gusiga amarangi ni uko dicyandiamide formaldehyde resin decolorizer igira ingaruka zikomeye kuri decolorisation yo gucapa no gusiga amazi mabi.Igipimo cyo gukuraho chroma gishobora kugera kuri 96%, kandi igipimo cyo gukuraho COD nacyo kigeze hejuru ya 70%.

Organic polymer flocculants yakoreshejwe bwa mbere mu myaka ya za 1950, cyane cyane amazi yo gutunganya amazi ya polyacrylamide, kandi polyacrylamide irashobora kugabanywamo ibice bitari ionic, anionic, na cationic.Muri iki kiganiro, tuzasobanukirwa na acrylamide polymer dicyandiamide formaldehyde resin decolorizing flocculant irimo umunyu wa amine ya quaternary amine muri cationic organic polymer polymer flocculants.

Dicyandiamide formaldehyde resin decolorizing flocculant ibanza gukorerwa hamwe na acrylamide hamwe na fordeque deque de l'hideque mu mazi ya alkaline, hanyuma igakorwa na dimethylamine, hanyuma ikonjeshwa ikanashyirwa hamwe na aside hydrochloric.Ibicuruzwa byibanda kumyuka no kuyungurura kugirango ubone monry acrylamide monater.

Dicyandiamide-formaldehyde condensation polymer decolorizing flocculant yatangijwe mu myaka ya za 90.Ifite ingaruka nziza cyane zo gukuraho ibara ryamazi yanduye.Mugutunganya amazi mabi menshi kandi yibanda cyane, hakoreshwa gusa polyacrylamide cyangwa polyacrylamide.Polyaluminium chloride flocculant ntishobora gukuraho burundu pigment, kandi nyuma yo kongeramo flokculant ya decolorizing, itesha agaciro amafaranga mabi yometse kuri molekile yamabara mumazi mabi atanga cations nyinshi bityo bigahungabanya Amaherezo, hashyizweho umubare munini wibimera, Irashobora gukuramo molekile y'irangi nyuma ya flocculation no guhungabana, kugirango ugere ku ntego ya decolorisation.

Uburyo bwo gukoresha decolorizer:

Uburyo bwo gukoresha decolorizing flocculant busa nubwa polyacrylamide.Nubwo iyambere iri muburyo bwamazi, igomba guhindurwa mbere yuko ikoreshwa.Uruganda arasaba ko rwongerwaho 10% -50%, hanyuma rukongerwamo amazi yimyanda hanyuma rukabyutsa neza.Kora indabyo za alum.Ikintu cyamabara mumazi mabi yamabara arazunguruka kandi agwa mumazi, kandi afite ibikoresho byo gutembera cyangwa guhinduranya ikirere kugirango bigere gutandukana.

Mu icapiro no gusiga irangi, imyenda nizindi nganda, gukoresha amazi ni binini cyane kandi igipimo cyo kongera gukoresha ni gito.Kubwibyo, guta umutungo wamazi birasanzwe cyane.Niba inzira ikoreshwa mugutunganya uburyo bunoze bwo gutunganya no gutunganya aya mazi mabi y’inganda kandi yibanda cyane, Ntabwo ishobora kuzigama umutungo w’amazi meza y’inganda gusa, ahubwo irashobora no kugabanya mu buryo butaziguye isohoka ry’amazi mabi y’inganda, aribyo bifite akamaro kanini kandi bigera kure mugutezimbere iterambere rirambye ryinganda zo gucapa, gusiga amarangi n’imyenda.

Byakuwe mubiguzi byoroshye.
