Irangi ryiza rifite imiterere myiza yo gusesa mumazi.Irangi rikora cyane cyane rishingiye kumatsinda ya acide sulfonique kuri molekile y'irangi kugirango ishonga mumazi.Kubirangi bya meso-ubushyuhe burimo amatsinda ya vinylsulfone, usibye amatsinda ya acide sulfonike Byongeye, β-etylsulfone sulfate nayo nitsinda ryiza cyane.Mu gisubizo cy’amazi, ion ya sodium yo mumatsinda ya acide sulfonique hamwe nitsinda rya -ethylsulfone sulfate ihura na hydratiya itera irangi gukora anion hanyuma igashonga mumazi.Irangi ryirangi ryirangi rishingiye kuri ion mbi yamabara kugirango irangi fibre.Amashanyarazi yamabara arenze 100 g / L.
Amashanyarazi menshi yamabara ni 200-400 g / l, kandi amarangi amwe arashobora no kugera kuri 450 g / l.
Ariko mugikorwa cyo gusiga irangi, ububobere bwirangi buzagabanuka kubera impamvu zitandukanye (cyangwa zidashobora gukemuka rwose).
Iyo ibishishwa by'irangi bigabanutse, igice cy'irangi kizahinduka kuva ion imwe yubusa itagabanijwe, kandi kwanga kwishyurwa hagati yibice bigabanuka cyane.
Ibice nuduce bizakururana kugirango bibe agglomeration
Muri ubu bwoko bwo kwegeranya, ibice by'irangi bikusanyiriza hamwe, hanyuma bigateranya, hanyuma bikarangira.Nubwo floc ari icyegeranyo kidakabije, kubera amashanyarazi abiri yakozwe namashanyarazi meza kandi mabi hirya no hino, biragoye ko imbaraga zogosha zinzoga zisanzwe zisize irangi, kandi floc byoroshye kumyenda.Imvura igwa hejuru, bikavamo kwanduza cyangwa kwanduza.
Irangi rimaze kugira agglomeration, ibara ryihuta rizagabanuka, kandi bizatera impamyabumenyi zitandukanye, irangi, nibara.Ku marangi amwe, flocs izakomeza kwihutisha inteko munsi yimbaraga zinzoga zisize irangi, bitera umwuma no gusohora.Iyo umunyu umaze kugaragara, ibara ryirangi rizahinduka urumuri rwinshi, cyangwa ntirisige irangi, kabone niyo ryaba risize irangi, ruzaba rufite amabara akomeye.
Gusiga irangi
Impamvu zo guteranya irangi
Impamvu nyamukuru ni electrolyte.Muburyo bwo gusiga irangi, electrolyte nyamukuru ni umuvuduko wihuta (ifu ya sodium sulfate n'umunyu).Ihuta ryirangi ririmo ion ya sodium, kandi ion ya sodium ihwanye na molekile y'irangi iri munsi cyane ugereranije niyihuta ryirangi.Umubare uhwanye na sodium ion hamwe nubusanzwe busanzwe bwihuta mugihe gisanzwe cyo gusiga amarangi ntabwo bizagira uruhare runini mugukemura kw'irangi mu bwogero bw'irangi.
Ariko, mugihe ubwinshi bwibikoresho bitera amarangi byiyongera, kwibumbira hamwe kwa sodium ion mubisubizo nabyo biriyongera.Iyoni nyinshi ya sodiumi izabuza ionisiyon ya sodium ion kumatsinda yashonze ya molekile irangi, bityo bigabanye imbaraga zo gusiga irangi.
Iyo kwibumbira hamwe kwihuta kurangi irangi 200 g / L, amarangi menshi azanyura murwego rutandukanye rwo kwegeranya.
Iyo kwibumbira hamwe kwihuta kurangi irangi 200 g / L, amarangi menshi azanyura murwego rutandukanye rwo kwegeranya.
Iyo kwibumbira hamwe kwa agent itera amarangi birenze 250 g / L, urwego rwa agglomeration ruzagenda rwiyongera, ubanze ugire agglomerate, hanyuma uhite ukora agglomerate na floccules munsi yimbaraga zogukemura igisubizo.Ku marangi amwe afite imbaraga nke, Igice cyacyo cyumunyu ndetse kikanagira umwuma.
Irangi rifite imiterere itandukanye ifite anti-agregation hamwe no kurwanya umunyu.Hasi yo kwikuramo, niko kurwanya anti-agregation hamwe no kurwanya umunyu.
Ihinduka ry'irangi rigenwa ahanini n'umubare w'amatsinda ya acide sulfonique muri molekile y'irangi n'umubare wa β-Ethylsulfone sulfate.
Muri icyo gihe, uko hydrophilicity ya molekile irangi irangi, niko bigenda byiyongera, kandi bikagabanuka hydrophilicity, niko bigabanuka..
Turi abatanga amarangi meza.Niba hari icyo ukeneye kubicuruzwa byacu, nyamuneka twandikire.
