Dicyandiamide formaldehyde resin decoloring agent

Mu gutunganya amazi yanduye mu nganda, gucapa no gusiga irangi amazi yanduye ni kimwe mu bitoroshye gutunganya. Afite imiterere igoye, agaciro ka chroma kari hejuru, ubwinshi bwayo buri hejuru, kandi biragoye kuyangiza. Ni imwe mu mazi yanduye yo mu nganda akomeye kandi agoranye gutunganya yanduza ibidukikije. Gukuraho chroma biragoye cyane mu bindi bibazo.

Mu buryo bwinshi bwo gucapa no gusiga irangi amazi yanduye, gukoresha uburyo bwo gufunga ni bwo buryo bukoreshwa cyane mu bigo. Muri iki gihe, imiti isanzwe ikoreshwa mu gucapa no gusiga irangi mu gihugu cyanjye ni imiti ikoreshwa muri aluminiyumu n'icyuma. Ingaruka zo gukuraho ibara ni mbi, kandi iyo irangi rikoreshwa rihinduwe ibara, nta ngaruka zo gukuraho ibara, kandi hazaba hakiri iyoni z'icyuma mu mazi yavuwe, ibyo bikaba bigifite ingaruka mbi ku mubiri w'umuntu no ku bidukikije.

Dicyandiamide formaldehyde resin decorating agent ni organic polymer flocculant, quaternary ammonium salt. Ugereranyije n'udukoko dusanzwe dusanzwe duca ibara, ifite umuvuduko wo gucika vuba, ingano nto, kandi igirwaho ingaruka n'imyunyu isanzwe, PH n'Ibyiza nko kuba ubushyuhe buke bugira ingaruka ku bushyuhe.

Dicyandiamide formaldehyde resin decoloring agent ni flocculant ikoreshwa cyane cyane mu gukuraho ibara no gukuraho COD. Mu kuyikoresha, ni byiza guhindura pH y'amazi yanduye kugira ngo ibe iyoroshye. Nyamuneka vugana n'abatekinisiye kugira ngo umenye uburyo bwihariye bwo kuyikoresha. Dukurikije ubufatanye bwinshi, ibitekerezo bitangwa n'abakora imashini zicapa n'izisiga irangi ni uko dicyandiamide formaldehyde resin decolorizer igira ingaruka zikomeye ku gukuraho ibara ry'amazi yanduye acapwa kandi agasigwa irangi. Igipimo cyo gukuraho chroma gishobora kugera ku kigero kirenga 96%, kandi igipimo cyo gukuraho COD nacyo cyageze ku kigero kirenga 70%.

Uduce twa polymer tw’umwimerere twakoreshejwe bwa mbere mu myaka ya 1950, cyane cyane utwo duce twa polyacrylamide two gutunganya amazi, naho polyacrylamide ishobora kugabanywamo utundi tubiri tutari ionic, anionic, na cationic. Muri iyi nkuru, turasobanukirwa n’utundi duce twa acrylamide polymer dicyandiamide formaldehyde duhindura ibara ry’uturemangingo, dushyirwamo umunyu wa quaternary amine mu tundi duce twa cationic organic polymer.

Dicyandiamide formaldehyde resin decolorizing flocculant ibanza gukoreshwa na acrylamide na formaldehyde aqueous solution mu gihe cy’ubushyuhe, hanyuma igakoreshwa na dimethylamine, hanyuma igakonjeshwa igashyirwamo aside hydrochloric. Umusaruro ushyirwamo umwuka hanyuma ukayungururwa kugira ngo haboneke monomer ya acrylamide yashyizwemo quaternized.

Dicyandiamide-formaldehyde condensation polymer decolorizing flocculant yatangijwe mu myaka ya 1990. Ifite ingaruka nziza cyane yo gukuraho ibara ry'amazi yanduye akoresha irangi. Mu kuvura amazi yanduye afite amabara menshi kandi afite ubucucike bwinshi, hakoreshwa polyacrylamide cyangwa polyacrylamide gusa. Polyaluminum chloride flocculant ntishobora gukuraho burundu irangi, kandi nyuma yo kongeramo flocculant decolorizing, ikuraho charge mbi ifatanye na molekile z'irangi mu mazi yanduye itanga cation nyinshi bityo igatuma adahinduka. Amaherezo, hakorwa umubare munini wa floccules, zishobora kwinjiza molekile z'irangi nyuma yo guhindagurika no kudahinduka, kugira ngo zigere ku ntego yo gukuraho ibara.

Uburyo bwo gukoresha decolorizer:

Uburyo bwo gukoresha flocculant ihindura ibara busa n'ubwa polyacrylamide. Nubwo iya mbere iri mu ishusho y'amazi, igomba gukurwamo amazi mbere yo kuyikoresha. Uwayikoze asaba ko ivangwaho 10%-50%, hanyuma yongerwa mu mazi yanduye hanyuma ikavangwa neza. Ikora indabyo za alum. Ibara ry'amazi ari mu mazi yanduye aravangwa akava mu mazi, kandi afite ibikoresho byo gusenya cyangwa kuzenguruka umwuka kugira ngo atandukane.

Mu nganda zicapa n’izisiga amarangi, imyenda n’izindi, amazi akoreshwa ni menshi cyane kandi igipimo cyo kongera gukoreshwa kiri hasi. Kubwibyo, gusesagura umutungo w’amazi ni ikintu gikunze kugaragara. Iyo uburyo bukoreshejwe mu gutunganya no kongera gukoresha amazi yanduye yo mu nganda afite amabara menshi kandi afite ubucucike bwinshi, ntabwo bushobora gusa kuzigama umutungo w’amazi menshi meza yo mu nganda, ahubwo bushobora no kugabanya mu buryo butaziguye isohoka ry’amazi yanduye yo mu nganda, ibi bikaba bifite akamaro kanini kandi kanini mu guteza imbere iterambere rirambye ry’inganda zicapa, zisiga amarangi n’imyenda.
