Dicyandiamide formaldehyde resin decoloring agent

Phakathi kokucocwa kwamanzi amdaka kwimizi-mveliso, ukuprinta kunye nokudaya amanzi amdaka yenye yezona zinto zinzima ukucocwa amanzi amdaka. Inokwakheka okuntsokothileyo, ixabiso eliphezulu le-chroma, uxinzelelo oluphezulu, kwaye kunzima ukuthoba. Lelinye lawona manzi amdaka emizi-mveliso anobuzaza kwaye kunzima ukuwaphatha angcolisa okusingqongileyo. Ukususwa kwechroma kunzima ngakumbi phakathi kobunzima.

Phakathi kweendlela ezininzi zokuprinta kunye nokudaya ukucocwa kwamanzi amdaka, ukusetyenziswa kwe-coagulation yeyona ndlela isetyenziswa kakhulu kumashishini. Okwangoku, iiflocculants eziqhelekileyo ezisetyenziselwa ukuprinta i-textile kunye nokudaya amashishini kwilizwe lam ziyi-aluminium-based and iron-based flocculants. Umphumo we-decolorization umbi, kwaye ukuba idayi esebenzayo i-decolorized, akukho phantse i-decolorization effect, kwaye kusekho ii-ion zetsimbi kumanzi acociweyo, okuseyingozi kakhulu kumzimba womntu kunye nokusingqongileyo.

I-Dicyandiamide formaldehyde resin decoloring agent yi-organic polymer flocculant, uhlobo lwetyuwa lwe-quaternary ammonium. Xa kuthelekiswa neeflocculants eziqhelekileyo ze-decolorizing, inesantya esikhawulezayo sokuhamba, idosi encinci, kwaye ichatshazelwa yityuwa ekhoyo, i-PH kunye ne-Advantages njengempembelelo encinci yobushushu.

I-dicyandiamide formaldehyde resin decoloring agent yiflocculant ikakhulu esetyenziselwa ukususwa kombala kunye nokususwa kweCOD. Xa uyisebenzisa, kucetyiswa ukuba ulungelelanise ixabiso le-pH lamanzi amdaka ukungathathi hlangothi. Nceda unxibelelane namagcisa ngeendlela ezithile zokusetyenziswa. Ngokwentsebenziswano emininzi Ingxelo evela kubavelisi bokushicilela kunye nokudaya yeyokuba i-dicyandiamide formaldehyde resin decolorizer inefuthe elibalulekileyo ekwenziweni kombala wokuprinta kunye nokudaya amanzi amdaka. Izinga lokususa i-chroma linokufikelela ngaphezu kwe-96%, kwaye izinga lokususa i-COD nalo lifikelele ngaphezu kwe-70%.

Organic polymer flocculants zaqala ukusetyenziswa kwiminyaka yoo-1950, ikakhulu polyacrylamide flocculants unyango lwamanzi, kunye polyacrylamide inokohlulwa ibe non-ionic, anionic, kunye cationic. Kweli nqaku, siya kuqonda i-acrylamide polymer dicyandiamide formaldehyde resin decolorizing flocculant enetyuwa nge-quaternary amine phakathi kwe-cationic organic polymer flocculants.

I-dicyandiamide formaldehyde resin decolorizing flocculant iqala ukusabela nge-acrylamide kunye ne-formaldehyde isisombululo samanzi phantsi kweemeko ze-alkaline, emva koko iphendule nge-dimethylamine, emva koko ipholile kwaye ifakwe i-quaternized nge-hydrochloric acid. Imveliso igxininiswe ngumphunga kwaye ihluzwe ukufumana i-quaternized acrylamide monoma.

I-dicyandiamide-formaldehyde condensation polymer decolorizing flocculant yaziswa ngo-1990. Inomphumo obalaseleyo obalaseleyo wokususa umbala wamanzi amdaka edayi. Kunyango lwamanzi amdaka aphezulu kunye noxinzelelo oluphezulu, kuphela i-polyacrylamide okanye i-polyacrylamide isetyenziswa. I-Polyaluminium chloride flocculant ayikwazi ukususa ngokupheleleyo i-pigment, kwaye emva kokufaka i-flocculant decolorizing, iyancipha intlawulo engafanelekanga efakwe kwi-molecule yedayi emanzini amdaka ngokubonelela ngobuninzi bee-cations kwaye ngaloo ndlela iphazamisekile ekugqibeleni, inani elikhulu le-floccules lenziwa, elinokuthi lifunxe i-molecule yedayi, i-deflobiculation kunye ne-deflobiculation. ukususwa kombala.

Uyisebenzisa njani i-decolorizer:

Indlela yokusebenzisa i-flocculant decolorizing iyafana naleyo ye-polyacrylamide. Nangona eyokuqala ikulwelo, kufuneka ixutywe phambi kokuba isetyenziswe. Umenzi uncoma ukuba ihlanjululwe nge-10% -50%, kwaye ifakwe kumanzi amdaka kwaye ixutywe ngokupheleleyo. Yenza iintyatyambo ze-alum. Umba onemibala kumanzi amdaka anemibala uyagxothwa kwaye aphume emanzini, kwaye axhotyiswe ngentlenga okanye i-air flotation ukuphumeza ukwahlukana.

Kwiindawo zokuprinta kunye nokudaya, i-textile kunye namanye amashishini, ukusetyenziswa kwamanzi kukhulu kakhulu kwaye izinga lokuphinda lisetyenziswe liphantsi. Ngoko ke, inkcitho yobutyebi bamanzi ixhaphake kakhulu. Ukuba inkqubo isetyenziselwa ukwenza unyango oluphezulu kunye nokuphinda kusetyenziswe lo manzi amdaka anombala ophezulu kunye noxinaniso oluphezulu lwemizi-mveliso, Ayinako nje ukugcina amanzi amaninzi asematsha akwimizi-mveliso, kodwa inokunciphisa ngokuthe ngqo ukukhutshwa kwamanzi amdaka kwimizi-mveliso, eyona nto ibaluleke kakhulu kwaye ibaluleke kakhulu ekukhuthazeni uphuhliso oluzinzileyo lokuprinta, ukudaya kunye nemizi-mveliso yelaphu.
