Odayi abahlakazekayo bajwayele ukuba nezinkinga ezifana nokudaya okungalingani, ukuhlanganisa kabusha, i-agglomeration kanye nokupheka.Indlela yokuvimbela?I-Disperse Dyeing Supplier izokwethula ngakho.
1. Ukudaya Okungalingani
Ukufana kokumuncwa kodayi kuhlobene nesilinganiso phakathi kwezinga lokugeleza kotshwala kanye nokumunca.Esigabeni sokumuncwa kombala, isiqondiso sokugeleza koketshezi siyashintshwa njalo emijikelezweni engu-8.Ukunciphisa isilinganiso sokugeza kusuka ku-1:12 kuya ku-1:6 kungashintsha ukufana kwesiteji sokufuduka, nakuba izinga lokungalingani ekuqaleni kokudaya libonakala nakakhulu.Lapho uxuba futhi udaya, akwanele ukukhetha odayi abanezakhiwo ezifanayo zokusabalalisa ukuze kuqinisekiswe ukudaya kwezinga.
Ngalesi sikhathi, isilinganiso sokuxuba sidlala indima ebalulekile.Uma inani lamadayi amathathu asetshenziswe ekufaniseni umbala lifana, kulungile ukusebenzisa odayi abanezici ezifanayo zokusabalalisa.Kodwa-ke, uma isilinganiso samadayi amabili sikhulu, i-diffusability yedayi yesithathu kufanele ibe ngaphansi, ngaphandle kwalokho izophela ngokushesha kunamanye amadayi amabili, okuzokwenza kalula ukudaya okungalingani.
2. Ukwenziwa kabusha kwekristalu
I-Disperse Dayeing ngokuvamile ihlanganisa izinhlayiya ezinkulu kuno-1nm ngenxa yokushisa nokupholisa okuphindaphindiwe.Ukwengeza ama-dispersants engeziwe kunganciphisa ukubuyiswa kabusha.Ngesikhathi sokudaya, lapho ukugeza okudaywayo kupholile kusuka ku-130 ° C kuya ku-90 ° C, abanye odayi ngokuvamile kulula ukuphinda bacwebezelise, okubangela ukushesha okungekuhle kokuhlikihla komkhiqizo odayiwe, ngisho nokuvala isihlungi ekushiseni okuphezulu kanye nomshini wokudaya onengcindezi ephezulu. .
Izinyathelo Zokuvimbela
Gcina i-100 ℃ isikhathi eside, udayi kulula ukuhlanganisa, lungisa isivinini sokushisa sisuka ku-100 ℃ siye ku-130 ℃;
Uma udayi okugeza udayi uphinda ukristale ngemva kokufinyelela ibhalansi yokudaya, i-disperant eyengeziwe kufanele yengezwe;
Abanye odayi abasabalalisa ababomvu bajwayele ukwenziwa kabusha njengekristalu ekupheleni kokudaya, ngisho noma ukugxilisa kwabo kuphansi kakhulu kuneleveli yokugcwala, ikakhulukazi uma kudayiwe imibala emnyama.Ikakhulukazi uma udaya ngamanzi aqinile, kulula ukuchela ngama-ion ensimbi.I-chelate ewumphumela ine-solubility embi ngaphansi kwezimo zokudaya futhi izoshiya amabala aluhlaza okwesibhakabhaka noma imigqa yombala endwangu.
Izici ezibangela ukubuyiswa kabusha
Izinsiza, uwoyela osongwayo, izinsalela ze-alkaline, njll. zengezwe ngesikhathi sokuphothwa.Lezi zinkinga zingagwenywa ngokucwenga ngaphambi kokudaya noma ukufaka ama-chelating agents ekugezeni okudayi.Uma ibala selivele, lingaqedwa ngokuhlanza ukuncishiswa kwe-alkali noma ukwelashwa kwe-asidi.
3. Agglomeration and Focus
Izici ezinomthelela
Kwenza buthaka umphumela wokuncibilika we-disperant, kunciphisa ukuphindisela kwe-electrostatic, futhi kukhuphule izinga lokushayisana kwezinhlayiya zikadayi futhi kuthuthukise amandla azo e-kinetic.Ngokuvamile, ukuphakama kokugxila kokudaya kanye nezinga lokushisa, futhi isikhathi eside sokudaya, makhulu amathuba okuba i-agglomeration ne-coke.Izinsiza zokudaya njengabathwali kanye nama-ejenti okulinganisa zingangena kalula esikhundleni se-disperant ehlanganiswe kudayi, ngaleyo ndlela kwehlise ukuzinza kokuhlakazeka.
Izinyathelo zokuthuthukisa ukuzinza ngesikhathi sokudaya
Hlakaza idayi ku-40 ° C futhi usebenzise ukuhlakazeka okugxilile;
Ukulawula izinga lokushisa okungcono kakhulu lapho utshwala obudayi bufudumala;
Ukusebenzisa i-disperant enomphumela we-colloidal ovikelayo;
Ungasebenzisi izithasiselo ezinephuzu lefu ekushiseni okuphezulu;
Geza bonke odayi kanye nezinsiza zezintambo ezihlanganisa ama-emulsifiers ngaphambi kokudaya;
Ngesikhathi sokushisa okuphezulu kokudaya, akukho nkampani yenethiwekhi kanye ne-ejenti yokulinganisa engeyona i-ionic okufanele yengezwe ngaphambi kokuba amadayi amaningi adayiwe endwangu;
Awukho usawoti, i-acetic kuphela yokulungisa inani le-PH;
Indwangu noma izindwangu ezidaywe ngezicucu kufanele zime ngendlela efanele, futhi ukuhlolwa kwaselabhorethri kufanele kwenziwe ukuze kuqinisekiswe ukuzinza kokuhlakazeka kodayi abahlakazayo.
