Dyeing pulp nrogDirect Yellow R.txhais tau hais tias muab cov dye rau hauv lub pulp thaum lub sij hawm papermaking txheej txheem.Qhov no ua kom ntseeg tau tias tag nrho qhov loj ntawm lub pulp yog uniformly xim los ntawmdirect Yellow Rdyes.

Cov lus qhia dav dav rau dyeing pulp los ntawm kev sivDirect Yellow Rraws li nram no:

1. Kev Npaj Dye Solution:

Npaj ib tug concentrated tov ntawmDirect Yellow Rdye los ntawm dissolving cov dye nyob rau hauv dej kub.Qhov concentration yuav txawv raws li qhov xav tau xim siv thiab qhov ntau ntawm cov tawv nqaij yuav dyed.

2. Kev npaj ntawm Pulp:

Xaiv lub pulp haum rau cov txheej txheem papermaking.Qhov no tuaj yeem yog ntoo pulp, paj rwb pulp, lossis lwm yam cellulose-based pulps.

Kho qhov sib xws ntawm lub pulp mus rau theem tsim nyog rau dyeing.Qhov no tej zaum yuav muaj kev diluting los yog kho lub pulp slurry mus rau qhov xav tau sib xws rau cov xim zoo nkag mus.

3. Kev koom ua ke ntawmDirect Yellow RXim:

Muab cov npaj Direct Yellow Rdye tov rau hauv lub pulp.Qhov no tuaj yeem ua tau ntau yam:

Nruam Cov Txheej Txheem: Ntxiv cov tshuaj zas xim rau lub pulp tsis tu ncua thaum lub sij hawm ua ntawv.

Batch txheej txheem: Sib tov covDirect Yellow Rdye tov nrog ib qho tshwj xeeb batch ntawm pulp nyob rau hauv ib lub thawv cais ua ntej qhia nws mus rau hauv cov txheej txheem papermaking.

4. Kev sib xyaw thiab homogenization:

Xyuas kom meej sib tov thiab homogenization ntawm Direct Yellow R dye tov nrog lub pulp.Qhov no tuaj yeem cuam tshuam los yog nplawm cov pulp-dye sib tov kom ua tiav cov xim tsis sib xws.

5. Papermaking txheej txheem:

Txuas ntxiv nrog cov txheej txheem papermaking li niaj zaus, sib txuas cov dyed pulp rau hauv lub tshuab papermaking.

Ua daim ntawv ntawv los ntawm cov dyed pulp los ntawm cov khoom tsim nyog papermaking, xws li cov txheej txheem, nias, thiab ziab theem.

6. Kev ziab thiab ua tiav:

Qhuav daim ntawv ntawv raws li tus txheej txheem papermaking.Xyuas kom qhuav kom tsim cov dye nyob rau hauv daim ntawv fibers.

Nyob ntawm cov kev cai tshwj xeeb, kev kho mob ntxiv lossis kev ua tiav yuav raug siv rau cov ntawv dyed los txhim kho nws cov khoom lossis kev ruaj ntseg.

7. Kev Tswj Xyuas Zoo thiab Kev Ntsuas:

Ua cov kev tswj xyuas zoo ntawm daim ntawv dyed kom paub meej cov xim sib xws, ceev ceev, thiab lwm yam khoom uas xav tau.

Ua cov kev ntsuam xyuas rau xim ceev, lightfastness, thiab lwm yam khoom muaj feem xyuam rau kev ntsuam xyuas cov xim ntawm cov ntawv.
