Utoto wobalalitsa umakonda kukhala ndi zovuta monga utoto wosiyanasiyana, recrystallization, agglomeration ndi kuphika.Kodi kupewa iwo?Disperse Dyeing Supplier akudziwitsani za izi.
1. Kupaka utoto Mosiyana
Kufanana kwa kuyamwa kwa utoto kumayenderana ndi chiŵerengero cha pakati pa kuchuluka kwa zakumwa zoledzeretsa ndi kuyamwa.Mu gawo la kuyamwa kwamtundu, komwe kumayendera madzi kumasinthidwa mizere 8 iliyonse.Kuchepetsa chiŵerengero cha kusamba kuchokera ku 1:12 mpaka 1: 6 kungasinthe kufanana kwa gawo la kusamuka, ngakhale kuti kuchuluka kwa kusagwirizana kumayambiriro kwa utoto kumakhala koonekeratu.Mukasakaniza ndi utoto, sikokwanira kusankha utoto wokhala ndi mawonekedwe ofananirako kuti muwonetsetse kuti utoto umakhala wofanana.
Panthawiyi, chiŵerengero chosakanikirana chimagwira ntchito yofunikira.Ngati kuchuluka kwa mitundu itatu yomwe imagwiritsidwa ntchito pofananiza mitundu ndi yofanana, ndikoyenera kugwiritsa ntchito utoto womwe uli ndi mawonekedwe ofanana.Komabe, ngati gawo la mitundu iwiri ndilokulirapo, kutayika kwa utoto wachitatu kuyenera kukhala kocheperako, apo ayi kuyenera kutha mwachangu kuposa mitundu iwiriyo, yomwe imayambitsa utoto wosagwirizana.
2. Recrystallization
Obalalitsa Kupaka utoto nthawi zambiri kumapangitsanso tinthu tating'ono tokulirapo kuposa 1nm chifukwa cha kutentha ndi kuzizira mobwerezabwereza.Kuwonjezera dispersants owonjezera akhoza kuchepetsa recrystallization.Panthawi yopaka utoto, malo osambira opaka utoto akazizira kuchokera pa 130 ° C mpaka 90 ° C, utoto wina nthawi zambiri umakhala wosavuta kuyikanso, zomwe zimapangitsa kuti zinthu zopaka zikhale zosasunthika, komanso kutsekereza fyuluta pakutentha kwambiri komanso makina odaya othamanga kwambiri. .
Njira Zopewera
Pitirizani 100 ℃ kwa nthawi yaitali, utoto ndi zosavuta agglomerate, kusintha Kutentha liwiro 100 ℃ kuti 130 ℃;
Ngati utoto mumtsuko wa utoto umawonekeranso ukafika pamlingo wodaya, wothira mafuta ambiri ayenera kuwonjezeredwa;
Utoto wina wobalalitsa wofiyira umakonda kupangidwanso kumapeto kwa utoto, ngakhale mawonekedwe ake ndi otsika kwambiri kuposa kuchuluka kwa machulukitsidwe, makamaka akadaya mitundu yakuda.Makamaka popaka utoto ndi madzi olimba, ndikosavuta ku chelate ndi ayoni achitsulo.Chelate yomwe imachokera imakhala yosasungunuka bwino pansi pa utoto ndipo imasiya mawanga abuluu kapena mikwingwirima pansalu.
Zomwe zimayambitsa recrystallization
Zothandizira, zopota mafuta, zotsalira za alkaline, ndi zina zomwe zimawonjezedwa panthawi yopota.Mavutowa atha kupewedwa poyenga musanadaye kapena kuwonjezera ma chelating agents mu bafa la utoto.Kuthimbirira kukachitika, kumatha kuthetsedwa ndi kuyeretsa kuchepetsa zamchere kapena chithandizo cha asidi.
3. Agglomeration ndi Focus
Zomwe zikuthandizira
Imafooketsa kutha kwa dispersant, imachepetsa kuthamangitsidwa kwa electrostatic, ndikuwonjezera kugunda kwa tinthu ta utoto ndikuwonjezera mphamvu zawo zamakinetic.Nthawi zambiri, kuchuluka kwa kuchuluka kwa utoto ndi kutentha, komanso nthawi yayitali yodaya, m'pamenenso kuthekera kwa kuphatikizika ndi coke kumakulirakulira.Zothandizira zopaka utoto monga zonyamulira ndi ma leveling agents zitha kulowetsa mosavuta dispersant osakanikirana mu utoto, potero zimachepetsa kukhazikika kwa kubalalitsidwa.
Njira zowongolera bata panthawi yopaka utoto
Imwaza utoto pa 40 ° C ndikugwiritsa ntchito kubalalitsidwa kokhazikika;
Kuwongolera bwino kwa kutentha pamene chakumwa cha utoto chatenthedwa;
Kugwiritsa ntchito dispersant ndi zoteteza colloidal zotsatira;
Osagwiritsa ntchito zowonjezera ndi mtambo pa kutentha kwakukulu;
Tsukani utoto ndi zida zonse za ulusi kuphatikiza zopangira ma emulsifiers musanadaye;
Pa kutentha kwapamwamba, palibe chonyamulira ndi chopanda ma ionic chomwe chiyenera kuwonjezeredwa musanayambe kupakidwa utoto wambiri pansalu;
Palibe mchere, asidi acetic okha kuti asinthe mtengo wa PH;
Nsalu za ulusi kapena zopakidwa utoto ziyenera kupangidwa moyenerera, ndipo kuyezetsa kwa ma labotale kuyenera kuchitika kuti kuwonetsetsa kukhazikika kwa utoto wobalalitsa.
