I-Reactive Dyeing inemeko entle kakhulu yonyibiliko emanzini.Idayi ezisebenzayo ikakhulu zixhomekeke kwiqela le-sulfonic acid kwimolekyuli yedayi ukuze inyibilike emanzini.Kwi-meso-temperature reactive dyes equlethe amaqela e-vinylsulfone, ngaphandle kwamaqela e-sulfonic acid Ukongeza, i-β-ethylsulfone sulfate yayo ikwayiqela elihle kakhulu lokunyibilika.Kwisisombululo esinamanzi, i-ion zesodium kwiqela le-sulfonic acid kunye neqela le-ethylsulfone sulfate lifumana impendulo ye-hydration ukuze idale ukuba idayi yenze i-anion kwaye inyibilike emanzini.Ukudaywa kweedayi ezisebenzayo kuxhomekeke kwii-ion ezingalunganga zedayi eziza kudaywa kwifiber.Ukunyibilika kwedayi ezisebenzayo kudlula i-100 g/L.
I-solubility yeedayi ezininzi yi-200-400 g / l, kwaye ezinye iidayi zinokufikelela kwi-450 g / l.
Kodwa kwinkqubo yokudaya, i-solubility yedayi iya kuncipha ngenxa yezizathu ezahlukeneyo (okanye i-insoluble ngokupheleleyo).
Xa i-solubility yedayi iyancipha, inxalenye yedayi iya kutshintsha ukusuka kwiyoni enye yamahhala ukuya kwiincinci, kwaye ukuchithwa kwentlawulo phakathi kweengqungquthela kuncitshiswe kakhulu.
Amasuntswana kunye namasuntswana aya kutsalana ukuze enze iagglomeration
Kolu hlobo lokudibanisa, amasuntswana edayi adityaniswa abe yi-aggregates, emva koko abe yi-aggregates, kwaye ekugqibeleni abe yiflocs.Nangona i-floc yingqokelela ekhululekileyo, ngenxa yombane ophindwe kabini owenziwe ngeentlawulo ezilungileyo nezingalunganga ezijikelezayo, kunzima ukuba i-shear force yotywala bedayi jikelele ukuyichitha, kwaye i-floc ilula kwilaphu.Imvula phezu komhlaba, okukhokelela ekungcoleni komhlaba okanye ekungcoleni.
Yakuba idayi inxulunyaniswe ngolo hlobo, ngokucacileyo iya kuphunguka umbala wayo, yaye iya kubangela amabala ahlukeneyo, amabala namabala.Kwezinye iidayi, i-flocs iya kukhawulezisa ngakumbi indibano phantsi kwe-shear force yotywala bedayi, ebangela ukuphelelwa ngamanzi emzimbeni kunye ne-salting ngaphandle.Emva kokuba i-salting iphume, umbala odayiweyo uya kuba lula kakhulu, okanye ungadayi, nokuba udayiwe, uya kuba ngumbala obomvu kunye namabala.
Ukudaya okuSebenzayo
Iimbangela zokudityaniswa kwedayi
Esona sizathu siphambili yi-electrolyte.Kwinkqubo yokudaya, i-electrolyte ephambili yidayi ekhawulezayo (i-sodium sulphate powder kunye netyuwa).I-accelerant yedayi iqulethe i-ion zesodium, kwaye i-ion yesodium elinganayo kwi-molecule yedayi iphantsi kakhulu kune-accelerant yedayi.Inani elilinganayo le-sodium ion kunye ne-concentration yesiqhelo ye-accelerator ngexesha lenkqubo eqhelekileyo yokudaya ayiyi kuba nefuthe elikhulu kwi-solubility yedayi kwindawo yokuhlamba idayi.
Nangona kunjalo, xa inani le-ejenti yokukhuthaza idayi inyuka, ukuxinwa kwee-ion ze-sodium kwisisombululo kwandisa.I-ion ye-sodium eyongeziweyo iya kuthintela i-ionization ye-sodium ion kumaqela anyibilikayo e-molecule yedayi, ngaloo ndlela inciphisa ukunyibilika kwedayi.
Xa i-concentration ye-accelerator yedayi idlula i-200 g / L, ezininzi iidayi ziya kuba needigri ezahlukeneyo zokuhlanganisa.
Xa i-concentration ye-accelerator yedayi idlula i-200 g / L, ezininzi iidayi ziya kuba needigri ezahlukeneyo zokuhlanganisa.
Xa ukuxinwa kwe-agent yokukhuthaza idayi kudlula i-250 g / L, iqondo le-agglomeration liya kuqinisa, kuqala ukwenza i-agglomerates, kwaye ngokukhawuleza yenze i-agglomerates kunye ne-floccules phantsi kwe-shear force yesisombululo sedayi.Kwezinye iidayi ezinokunyibilika okuphantsi, Inxalenye yayo igalelwe ityuwa kwaye ide iphelelwe ngamanzi.
Iidayi ezinezakhiwo ezahlukeneyo zeemolekyuli zineendlela ezahlukeneyo zokuchasana kunye nokumelana netyuwa.I-solubility esezantsi, kokukhona i-anti-aggregation imbi kunye nokumelana ne-salting-out.
I-solubility yedayi inqunywe ngokukodwa ngamanani e-sulfonic acid amaqela kwi-molecule yedayi kunye nenani le-β-ethylsulfone sulfates.
Kwangaxeshanye, okukhona i-hydrophilicity ye-molecule yedayi, iphezulu ukunyibilika, kwaye isezantsi i-hydrophilicity, isezantsi ukunyibilika.(Umzekelo, iidayi ezine-azo structure zingaphezulu kwe-hydrophilic kunedayi ezinesakhiwo se-heterocyclic.) Ukongezelela, i-molecular structure yedayi inkulu, i-solubility ephantsi, kunye nencinci ye-molecular structure, i-solubility ephezulu.
