ʻO nā mea hoʻohui kemika no ka slurry wai lanahu, ʻo ia nō nā dispersants, stabilizers, defoamers a me ka corrosion inhibitors, akā e pili ana i nā dispersants a me nā stabilizers.ʻO ka sodium lignosulfonateʻO ia kekahi o nā mea hoʻohui no ka slurry wai lanahu.

ʻO nā pono o ka noisodium lignosulfonatei loko o ka wai lanahu slurry additives penei:

1. ʻOi aku ka maikaʻi o ka dispersion sodium ma mua o ka magnesium lignosulphonate a me ka lignamine, a ʻoi aku ka maikaʻi o ka slurry wai lanahu i hoʻomākaukau ʻia. ʻO ka nui o ka lignin i loko o ka slurry wai lanahu aia ma waena o 1% - 1.5% (e like me ka nui o ke kaumaha o ka slurry wai lanahu), i hiki ke hoʻomākaukau ʻia ka slurry wai lanahu me 65%, a hiki i ke kūlana kiʻekiʻe. slurry wai lanahu.

2. ʻO ka sodium lignosulfonatehiki ke hiki i ka 50% o ka mana dispersant o ka naphthalene system, no laila, pono ka naphthalene system 0.5%. Ke noʻonoʻo nei i ke kumukūʻai, ʻoi aku ka maikaʻi o ka hoʻohanasodium lignosulfonatee like me ka dispersant o ka slurry wai lanahu.

3. ʻO ka maikaʻi o ka slurry wai lanahu i hana ʻia e ka dispersant ʻo ia ke kūpaʻa maikaʻi a ʻaʻole e hoʻopuka i ka ua paʻakikī i nā lā 3, akā ʻo ka slurry wai lanahu i hana ʻia e naphthalene dispersant e hoʻohua i ka ua paʻakikī i nā lā 3.

4. ʻO ka sodium lignosulfonateHiki ke hoʻohana pū ʻia ka dispersant me ka naphthalene a i ʻole aliphatic dispersant. ʻO ka ratio kūpono o ka lignin me ka dispersant naphthalene he 4:1, a ʻo ka ratio kūpono o ka lignin me ka dispersant aliphatic he 3:1. E hoʻoholo ʻia ka nui kikoʻī o ka hoʻohana e like me ke ʻano o ka lanahu a me nā koi manawa.

5. ʻO ka hopena dispersion o ka lignin dispersant e pili ana i ka maikaʻi o ka lanahu. ʻO ke kiʻekiʻe o ke kiʻekiʻe o ka metamorphism lanahu, ʻoi aku ka kiʻekiʻe o ka wela o ka lanahu, ʻoi aku ka maikaʻi o ka hopena dispersion. ʻO ka haʻahaʻa o ka calorific waiwai o ka lanahu, ʻoi aku ka nui o ka lepo, humic acid a me nā mea haumia ʻē aʻe, ʻoi aku ka maikaʻi o ka hopena.
