ʻO ka sodium lignosulfonatehe polimer maoli.He huahana ia o ka hana pulp, he polymer o 4-hydroxy-3-methoxybenzene.Loaʻa iā ia ka dispersibility ikaika.Ma muli o nā kaumaha molekala like ʻole a me nā pūʻulu hana, loaʻa iā ia nā degere like ʻole o ka dispersibility.He mea ʻeleu ili ia e hiki ke hoʻopili ʻia ma ka ʻili o nā ʻāpana paʻa like ʻole a hiki ke hana i ka hoʻololi ion metala.Loaʻa iā ia nā pūʻulu ikaika like ʻole i kona ʻano, no laila hiki iā ia ke hana i ka condensation a i ʻole ka hoʻopaʻa hydrogen me nā mea ʻē aʻe.
Ma muli o kona kūlana kūikawā,sodium lignosulfonateLoaʻa i nā waiwai physicochemical ili e like me ka dispersion, emulsification, solubilization a me adsorption.Hoʻohana ʻia kāna mau huahana i hoʻololi ʻia e like me ka mineral nutrient surfactant, a ua oʻo ke kaʻina hana.

Hoʻohana kumukānāwai osodium lignosulfonate:
ʻOkoʻa ka helu o nā kaulahao kalapona e like me nā mea like ʻole i lawe ʻia mai ka lignin.He kūpono kekahi no ka hoʻoulu ʻana i ka mea kanu a kūpono kekahi no nā mea hoʻohui pesticide.Loaʻa iā ia nā ʻano hana hana like ʻole, dispersibility a me ka chelation, maʻalahi e hui pū me nā mea metala e hana i ke kūlana chelate, hoʻomaikaʻi i ke kino a me nā waiwai o nā mea kanu metala, mālama i nā kumukūʻai a hoʻomaikaʻi i ka pono.ʻO nā waiwai adsorption a me ka hoʻokuʻu lohi o ka lignin hiki ke mālama maikaʻi i ka maikaʻi o ka mea kanu kemika a hoʻokuʻu mālie.He mea hoʻokuʻu lohi maikaʻi ia no ka mea hoʻohuihui organik.ʻO Lignin kahi ʻano polycyclic macromolecular organic compound i loaʻa nā pūʻulu maikaʻi ʻole, nona ka pilina ikaika no nā ion metala kiʻekiʻe i ka lepo.
ʻO ka sodium lignosulfonatehiki ke hoʻohana ʻia no ka hana pesticide.Loaʻa i ka Lignin kahi ʻāpana kikoʻī kikoʻī nui a loaʻa nā ʻano hui ikaika, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻokuʻu lohi pesticide.
Aia nā ʻokoʻa ma waena o ka lignin i nā mea kanu a me ka lignin ma hope o ka kaʻawale ʻana.ʻO ka paia pūnaewele hou i hanaʻia o ka māhele pūnaewele mea kanu he lahilahi a waiwai i nā polysaccharides acidic e like me pectin, e hoʻohua mālie i ka cellulose a me ka hemicellulose.Hoʻokaʻawale ʻia nā cell i nā ʻāpana xylem kūʻokoʻa (nā lāʻau fibers, tracheids a me nā moku, etc.).Ke hoʻokumu ʻia ka papa S1 o ka pā lua, hoʻomaka ka lignin e hana mai nā kihi o ka pā mua.Kapa ʻia kēia ʻano he lignification.Me ka oʻo ʻana o ka ʻiʻo mea kanu, ulu ka lignification i ka papa intercellular, ka pā mua a me ka pā lua.Hoʻokomo mālie ʻia ʻo Lignin i loko a ma waena o nā paia o ke kelepona, e hoʻopaʻa pū ana i nā cell a me nā cell.I ka wā o ka lignification o nā paia o nā mea kanu, komo ka lignin i loko o nā paia o ke kelepona, e hoʻonui ana i ka paʻakikī o nā paia o ke kelepona, e hoʻoikaika ana i ka hoʻokumu ʻana o nā ʻiʻo mechanical, a me ka hoʻonui ʻana i ka ikaika mechanical a me ka hiki ke halihali i nā mea kanu a me nā ʻiʻo;Hana ʻo Lignin i ka hydrophobic o ka pā hale a hoʻolilo i nā mea kanu i ʻike ʻole ʻia, e hāʻawi ana i kahi hōʻoia hilinaʻi no ka lawe lōʻihi ʻana o ka wai, nā minerala a me nā mea kūlohelohe i loko o ke kino mea kanu;ʻO ka hoʻokomo ʻana o ka lignin i loko o ka paia o ke kelepona e hana i kahi pale kino, e pale pono i ka hoʻouka ʻana o nā mea kanu like ʻole;Kāohi ia i nā molekole conduction i loko o ka xylem mai ke kahe ʻana o ka wai, a ma ka manawa like e hiki ai i nā mea kanu honua ke ola i kahi ʻano maloʻo, e hoʻonui ai i ka pale ʻana o ka mea kanu.He kuleana ko Lignin i ka hoʻopaʻa ʻana i ka cellulose, hemicellulose a me nā paʻakai inorganic (ka nui o ka silicate) i nā mea kanu.
ʻO nā kumu e pili ana i ka decomposition lignin e pili ana i ka pH lepo, ka maʻa a me nā kūlana climatic.ʻO nā kumu ʻē aʻe, e like me ka loaʻa ʻana o ka nitrogen a me ka mineralogy lepo, he hopena pū kekahi.Hiki i ka adsorption o Fe a me Al oxides ma ka lignin ke hoemi i ka decomposition o ka lignin.
