Tshuaj additives rau thee dej slurry yeej muaj xws li dispersants, stabilizers, defoamers thiab corrosion inhibitors, tab sis feem ntau xa mus rau dispersants thiab stabilizers.Sodium lignosulfonateyog ib qho ntawm cov additives rau cov dej slurry.

Daim ntawv thov zoo ntawmsodium lignosulfonateNyob rau hauv coal dej slurry additives yog raws li nram no:

1. Sodium lignosulphonate muaj cov nyhuv dispersion zoo dua li magnesium lignosulphonate thiab lignamine, thiab cov thee npaj cov dej slurry muaj fluidity zoo dua. Qhov ntau npaum lignin nyob rau hauv cov thee dej slurry yog nruab nrab ntawm 1% - 1.5% (raws li tag nrho qhov hnyav ntawm cov dej slurry), kom cov thee dej slurry nrog ib tug concentration ntawm 65% tuaj yeem npaj tau, ncav cuag tus qauv siab. coal dej slurry.

2. Sodium lignosulfonatetuaj yeem ncav cuag 50% ntawm lub peev xwm dispersant ntawm naphthalene system, yog li cov naphthalene system xav tau 0.5%. Xav txog tus nqi, nws raug nqi ntau dua rau kev sivsodium lignosulfonateraws li cov dispersant ntawm thee dej slurry.

3. Qhov zoo ntawm cov dej slurry ua los ntawm dispersant yog tias nws muaj kev ruaj ntseg zoo thiab yuav tsis tsim cov nag lossis daus hauv 3 hnub, tab sis cov dej coal slurry ua los ntawm naphthalene dispersant yuav ua rau nag lossis daus nyuaj hauv 3 hnub.

4. Sodium lignosulfonatedispersant kuj tuaj yeem siv ua ke nrog naphthalene lossis aliphatic dispersant. Qhov sib piv ntawm lignin rau naphthalene dispersant yog 4: 1, thiab qhov sib piv ntawm lignin rau aliphatic dispersant yog 3: 1. Qhov tshwj xeeb ntawm kev siv yuav raug txiav txim raws li qhov tshwj xeeb thee hom thiab lub sijhawm xav tau.

5. Cov nyhuv dispersion ntawm lignin dispersant muaj feem xyuam rau qhov zoo ntawm cov thee. Qhov siab dua ntawm cov thee metamorphism, qhov kub ntawm cov thee ntau dua, qhov zoo dua qhov cuam tshuam. Qhov qis dua tus nqi calorific ntawm cov thee, cov av nkos ntau, humic acid thiab lwm yam impurities, qhov cuam tshuam loj dua.
