Izalathisi eziphambili ezilishumi zeDayi eziReactive

Iiparamitha ezilishumi zokudaya okusebenzayo ziquka: iimpawu zokudaya S, E, R, F amaxabiso.Isalathiso sokufuduka kwexabiso le-MI, inqanaba lokudaya ixabiso le-LDF, i-WF elula yokuhlamba ixabiso, ukuphakamisa isalathisi se-BDI ixabiso / ixabiso le-inorganic value, ixabiso le-organic (I / O) kunye ne-solubility, iiparitha ezilishumi eziphambili zentsebenzo ephambili yeedayi ezisebenzayo ezifana;Ukuthathwa kwedayi, ukuchaneka, ukusebenza kwakhona, izinga lokulungiswa, ukulinganisa, ukuveliswa kwakhona, ukuhambelana kwedayi ezixutywe kunye nokukhawuleza kombala zizikhokelo ezibalulekileyo.

1. Ukuthe ngqo

I-S imele ukuchaneka kwedayi kwifiber, ebonakaliswe yizinga le-adsorption xa i-adsorbed imizuzu engama-30 ngaphambi kokongeza i-alkali.

2. Ukuphinda usebenze

I-R imele i-reactivity yedayi, ebonakaliswe ngesantya sokulungiswa emva kwemizuzu emi-5 yokongeza i-alkali.

3. Isantya sokudinwa kwedayi

I-E imele izinga lokudinwa lokudaya, elibonakala ngobunzulu bombala bokugqibela kunye nomlinganiselo wedosi.

Ukudaya okuSebenzayo

Okwesine, izinga lokulungiswa

I-F imele izinga lokulungiswa kwedayi, isantya sokulungiswa kwedayi emva kokuba idayi ihlanjwe kumbala odadayo.Izinga lokulungiswa lihlala liphantsi kunomlinganiselo wokudinwa.

Amaxabiso e-S kunye no-R angachaza ireyithi yokudaya kunye nesantya sokusabela kwedayi ezisebenzayo.Zinxulumene nokufuduka kwedayi kunye neempawu zokulinganisa.I-E kunye ne-F inxulumene nokusetyenziswa kwedayi, ukuvasa ngokulula kunye nokukhawuleza.

5. Ukufuduka

I-MI: MI = C / B * 100%, apho i-B imele umlinganiselo wedayi oseleyo welaphu elidayiweyo emva kovavanyo lokufuduka, kwaye i-C yidayi yokuthatha ilaphu elimhlophe emva kovavanyo lokufuduka.Iphezulu ixabiso le-MI, ngcono umgangatho.Ixabiso le-MI elikhulu kune-90% yidayi eneempawu ezintle zokudaya.

Isithandathu, ukuhambelana

I-LDF: LDF=MI×S/ELDF ixabiso elikhulu kune-70 libonisa umgangatho ongcono wokudaya.

I-RCM: I-Reactive dayi ehambelanayo yento, equkethe izinto ezi-4, i-S, MI, i-LDF kunye nesiqingatha sedayi yexesha T yedayi esebenzayo phambi kwe-alkali.

Ukuze kuphunyezwe izinga eliphezulu lempumelelo yokuqala, ixabiso le-RCM ligqitywe ngokubanzi kuluhlu olulandelayo, i-S=70-80% kwi-electrolyte engathathi hlangothi, i-MI inkulu kune-90%, i-LDF inkulu kune-70%, kunye nexesha lokudaya isiqingatha sikhulu. ngaphezu kwemizuzu eli-10.

Zisixhenxe, kulula ukuzihlamba

WF: WF=1/S(EF), ngokuqhelekileyo izinga lokulungiswa kwedayi ezisebenzayo lingaphantsi kwe-70%, (EF) inkulu kune-15%, kwaye xa i-S ingaphezu kwe-75%, kukho imibala edadayo kwaye kunzima susa, ngoko abanakusetyenziswa njengemibala enzulu.ukudaya.

8. Amandla okuphakamisa

I-BDI: Isalathiso samandla okunyusa, ekwabizwa ngokuba yi-daying saturation value.Ukuba ufuna ukunyusa ubunzulu, inani ledayi liye landa ngokubanzi, kodwa idayi enamandla okunyusa aphantsi ayinyuki ngobunzulu njengoko inani ledayi linyuka ukuya kwinqanaba elithile.Indlela yovavanyo: ngokusekwe kwisivuno esibonakalayo sombala welaphu elidayiweyo elilinganiswe phantsi komgangatho wechromaticity (efana ne-2% njengomgangatho), isivuno esibonakalayo sombala wamalaphu adayiweyo echromaticity nganye kunye nomgangatho wechromaticity kunye nesixa esonyukayo sedayi. ubuninzi bombala.

Isithoba, ixabiso le-I/O

I/O ixabiso: Abantu babiza i-hydrophobic (engeyo-polar) inxalenye ye-organic substance i-organic base part, kunye ne-hydrophilic (polar) inxalenye ibizwa ngokuba yi-inorganic essential base part.Emva kokudibanisa amaxabiso amaqela ahlukeneyo Emva koko wahlule isixa seqela le-polar kunye neqela elingekho-polar ukufumana ixabiso.Ixabiso le-I / O limele ukuhanjiswa kwedayi kwifiber kunye nedayi yotywala.Oku kukwasisalathisi esibaluleke kakhulu sendlela yokukhetha imibala ephambili emithathu.

10. Ukunyibilika

I-solubility engcono yedayi, ibanzi uluhlu lwesicelo.Kukho iindlela ezimbini zokuphucula ukunyibilika: enye kukongeza ezinye iiarhente zokumanzisa ezinezakhiwo ezikhethekileyo ukwenza idayi zimanzi ngokukhawuleza emanzini, kwaye emva koko ngealkyl naphthalene sulfonic acid formaldehyde condensate series dispersants ukwenza iimolekyuli ezinxulumene nedayi ibe nye. Imolekyuli .Indlela yesibini kukudibanisa iisomers zedayi ezisebenzayo.

Singumthengisi we-Reactive Dyeing, ukuba unomdla kwiimveliso zethu, nceda uzive ukhululekile ukuqhagamshelana nathi.
