Ibibazo Bisanzwe hamwe nuburyo bwo kwirinda bwo gusiga irangi

Irangi ritatanye rikunze guhura nibibazo nko gusiga irangi ridasa, kongera gukora, agglomeration hamwe na kokiya.Nigute wabirinda?Disperse Dyeing Supplier azakumenyesha kubyerekeye.

1. Irangi ridahwanye
Uburinganire bwo kwinjiza amarangi bufitanye isano nikigereranyo kiri hagati yumuvuduko wibinyobwa byinzoga.Mu cyiciro cyo kwinjiza amabara, icyerekezo cyamazi atemba gihinduka buri cyiciro 8.Kugabanya igipimo cyo kwiyuhagira kuva 1:12 kugeza 1: 6 birashobora guhindura uburinganire bwicyiciro cyimuka, nubwo urwego rwuburinganire mugitangira irangi rugaragara.Iyo kuvanga no gusiga irangi, ntibihagije guhitamo amarangi afite imiterere isa nogukwirakwiza kugirango irangi ryurwego.

Muri iki gihe, igipimo cyo kuvanga kigira uruhare runini.Niba ingano y'amabara atatu akoreshwa muguhuza amabara ni amwe, birakwiye gukoresha amarangi afite imiterere imwe yo gukwirakwiza.Ariko, niba igipimo cyamabara abiri ari kinini, ikwirakwizwa ryirangi rya gatatu rigomba kuba rito, naho ubundi rizananirwa vuba kurusha andi marangi abiri, bizatera byoroshye irangi ridasa.

2. Gusubiramo
Gusiga irangi akenshi usubiramo ibice binini birenze 1nm kubera gushyushya no gukonjesha.Ongeraho inyongeramusaruro zirashobora kugabanya kongera gukora.Mugihe cyo gusiga irangi, iyo ubwogero bwo gusiga bukonje kuva kuri 130 ° C kugeza kuri 90 ° C, amarangi amwe akunze koroha kongera kuyasubiramo, bikaviramo kwangirika nabi kubicuruzwa bisize irangi, ndetse no gufunga akayunguruzo mubushyuhe bwinshi hamwe nimashini isiga irangi ryinshi. .

Ingamba zo kwirinda
Gumana 100 ℃ umwanya muremure, irangi ryoroshye guhuriza hamwe, hindura umuvuduko wo gushyushya kuva 100 ℃ kugeza 130 ℃;

Niba irangi mu bwogero bwo gusiga irangi ryongeye guhinduka nyuma yo kugera ku gipimo cyo gusiga irangi, hagomba kongerwamo izindi dispers;

Amabara amwe atukura atukura akunda kongera guhindurwa nyuma yo gusiga irangi, nubwo kwibanda kwabo ari munsi cyane kurwego rwo kwiyuzuzamo, cyane cyane iyo usize amabara yijimye.Cyane cyane iyo usize irangi namazi akomeye, biroroshye gushiramo ioni yicyuma.Chelate yavuyemo ifite ubushobozi buke bwo gusiga irangi kandi izasiga ibibara byubururu cyangwa ibara ryamabara kumyenda.

Ibintu bitera kongera gukora

Abafasha, amavuta azunguruka, ibisigazwa bya alkaline, nibindi byongewe mugihe cyo kuzunguruka.Ibi bibazo birashobora kwirindwa mugutunganya mbere yo gusiga irangi cyangwa kongeramo imiti ya chelating mubwogero bwo gusiga irangi.Iyo ikizinga kimaze kugaragara, kirashobora gukurwaho no kugabanya alkaline yoza cyangwa kuvura aside.

3. Guhuriza hamwe no kwibanda

Impamvu zitanga umusanzu
Igabanya imbaraga zo gushonga kwa dispersant, igabanya kwanga electrostatike, kandi ikongera umuvuduko wo kugongana kwingirangingo yamabara kandi ikazamura ingufu za kinetic.Mubisanzwe, hejuru yo gusiga irangi hamwe nubushyuhe, hamwe nigihe kinini cyo gusiga, niko bishoboka ko agglomeration na kokiya.Abafasha gusiga amarangi nk'abatwara hamwe n'abashinzwe kuringaniza ibintu birashobora gusimbuza byoroshye ibitandukanya bivanze mu irangi, bityo bikagabanya ituze.

Ingamba zo kunoza ituze mugihe cyo gusiga irangi
Kurangi irangi kuri 40 ° C hanyuma ukoreshe gutatanya;

Kugenzura ubushyuhe bwiza iyo inzoga zisize irangi;

Gukoresha dispersant hamwe ningaruka zo gukingira;

Ntukoreshe inyongeramusaruro hamwe nigicu hejuru yubushyuhe bwinshi;

Koza amarangi yose hamwe nabafasha b'intambara harimo na emulisiferi mbere yo gusiga irangi;

Mugihe cyo gusiga irangi ryubushyuhe bwinshi, ntamutwara nu mutungo utari ionic ugomba kongerwaho mbere yuko amarangi menshi asiga irangi kumyenda;

Nta munyu, aside aside gusa kugirango ihindure agaciro ka PH;

Imyenda cyangwa imyenda irangi irangi igomba kuba yarateguwe neza, kandi hagomba gukorwa ibizamini bya laboratoire kugirango itandukanyirizo ryamabara atatanye.
