Ihe mgbakwunye kemịkalụ maka coal mmiri slurry n'ezie gụnyere dispersants, stabilizers, defoamers na corrosion inhibitors, ma n'ozuzu na-ezo aka dispersants na stabilizers.Sodium lignosulfonatebụ otu n'ime ihe mgbakwunye maka coal water slurry.

The ngwa uru nkesodium lignosulfonatena coal water slurry mgbakwunye bụ ndị a:

1. Sodium lignosulphonate nwere mma dispersion mmetụta karịa magnesium lignosulphonate na lignamine, na njikere coal mmiri slurry nwere mma fluidity. Usoro onunu ogwu nke lignin na coal mmiri slurry dị n'etiti 1% - 1.5% (dị ka ngụkọta arọ nke coal mmiri slurry), nke mere na coal mmiri slurry na a ịta nke 65% nwere ike kwadebere, na-eru ọkọlọtọ nke elu ịta. coal mmiri slurry.

2. Sodium lignosulfonatenwere ike iru 50% nke dispersant ike nke naphthalene usoro, otú naphthalene usoro chọrọ 0,5%. N'ịtụle ọnụahịa ahụ, ọ na-akwụ ụgwọ karịa ijisodium lignosulfonatedị ka dispersant nke coal mmiri slurry.

3. Uru nke coal water slurry mere site na dispersant bụ na ọ nwere ezigbo nkwụsi ike na ọ gaghị emepụta mmiri ozuzo siri ike n'ime ụbọchị 3, ma mmiri ọkụ nke naphthalene na-ekesa ga-emepụta mmiri ozuzo siri ike na ụbọchị 3.

4. Sodium lignosulfonateA pụkwara iji ihe nkesa na-ejikọta ya na naphthalene ma ọ bụ aliphatic dispersant. Oke kwesịrị ekwesị nke lignin na naphthalene dispersant bụ 4: 1, na nha kwesịrị ekwesị nke lignin na aliphatic dispersant bụ 3: 1. A ga-ekpebi ego ole a ga-eji eme ihe dị ka ụdị coal akọwapụtara na oge achọrọ.

5. Mmetụta mgbasa nke lignin dispersant metụtara àgwà nke coal. N'ịdị elu nke coal metamorphism, ka okpomọkụ nke coal dị elu, mmetụta mgbasawanye ka mma. Na ala calorific uru nke coal, ka apịtị, humic acid na ndị ọzọ adịghị ọcha, ka njọ mgbasa mmetụta.
