Iarhente yokusasaza iMF(ekwabizwa ngokuba yi-diffuser MF) yi-formaldehyde condensation ye-sodium methylate. Nangona kunjalo, kuyaziwa ukuba ukusetyenziswa kwayo kuncinci. Namhlanje ndiza kudwelisa ukusetyenziswa kwe-disperant MF.
Iarhente yokusasaza iMFisetyenziswa ngolu hlobo lulandelayo:
I-1 ye-disperant MF ingasetyenziselwa ukunciphisa, i-disperse yedayi ingasetyenziselwa ukugaya i-dispersant kunye nomgangatho wokuzaliswa, ingasetyenziselwa ukuveliswa kwe-arhente yokusabalalisa iqela lombala.
2. Kushicilelo kunye neshishini lokudaya,Iarhente yokusasaza iMFsisicinezeli sedayi ye-VAT, esetyenziselwa ukudaya ngechromoacid ezinzileyo kunye nokudaya kwe-disperse kunye nedayi ye-VAT enyibilikayo.
3. I-Disperant MF isetyenziswa njengesongezo kwishishini lesikhumba kwaye njengesizinziso se-latex kwishishini lerabha.
4. I-Disperant MF inokunyibilikisa ikhonkrithi kwi-arhente yokunciphisa amanzi anamandla, inciphise ixesha lokwakha, igcine isamente, igcine amanzi kunye nokuphucula amandla e-samente.
I-Disperant MF isetyenziswa ikakhulu njenge-dispersant kunye ne-filler kwiidayi ze-VAT kunye nedayi yokusasaza, kwaye isetyenziswa ikakhulu njenge-ejenti yokucubungula kunye ne-disperant yokupholisha iidayi ezisasazwayo kunye nedayi ye-VAT, ngokusebenza okungcono kune-disperant N.
Iindlela zokusetyenziswa
I-diffusivity enhle kunye ne-colloid ekhuselayo, akukho ukungena kunye ne-foam.
I-Dispersants zi-surfactants eziyi-hydrophilic kunye ne-hydrophilic kwaye siye sathetha ngale nto amaxesha amaninzi, i-dipersants inokusasaza ngokulinganayo amasuntswana aqinileyo kunye nolwelo lwezixhobo kunye ne-organic pigments ekunzima ukuyinyibilikisa kulwelo, ukuthintela amasuntswana ukuba angazinzi kwaye aqokelele, enze iiarhente. efunekayo ukuzinzisa ukumiswa. Indima ye-dispersant kukusebenzisa i-wetting dispersant ukunciphisa ixesha kunye namandla afunekayo ukugqiba inkqubo yokusabalalisa, ukuzinzisa ukusabalalisa kwe-pigment, ukuguqula iimpawu zomphezulu we-pigment particles, ukulungelelanisa ukuhamba kwee-pigment particles.
Iimpawu ze-carbon black dispersant esekwe emanzini:
1. I-Organic kunye ne-inorganic pigments ine-dispersion yokumanzisa elungileyo kunye nezinzileyo, ngakumbi ilungele ukusasaza i-carbon black pigments.
2. Ukubonelela ngokwandisa umbala kunye nokuzinza;
3. Ngaphantsi komxholo we-pigment ephezulu, inkqubo ye-pigment dispersion ephantsi ye-viscosity inokufumaneka.
Ububanzi besicelo: intlama yombala esekelwe kumanzi ngokusingqongileyo, i-inki esekwe emanzini.
Isicelo: okokuqala ukusabalalisa i-dispersant kwi-medium-based medium, kwaye emva koko ungeze i-coating yokugaya ngesantya esiphezulu.
