ʻO Lignin ka lua wale nō i ka cellulose i loko o nā mālama kūlohelohe, a ua hana hou ʻia ma ka helu o 50 biliona tons i kēlā me kēia makahiki. Hoʻokaʻawale ka ʻoihana pulp a me ka pepa ma kahi o 140 miliona tons cellulose mai nā mea kanu i kēlā me kēia makahiki, a loaʻa ma kahi o 50 miliona tons o nā huahana lignin, akā i kēia manawa, ʻoi aku ka nui o ka 95% o ka lignin i hoʻokuʻu pololei ʻia i loko o nā muliwai a i ʻole nā ​​muliwai e like me " waiʻona ʻeleʻele”. Ma hope o ka hoʻopaʻa ʻia ʻana, puhi ʻia a ʻaʻole hoʻohana maikaʻi ʻia. ʻO ka piʻi ʻana o ka ikehu mōʻalihaku, ka nui o ka lignin, a me ka ulu wikiwiki ʻana o ka ʻepekema lignin e hoʻoholo i ka hoʻomohala mau ʻana o nā pono waiwai o ka lignin.

He haʻahaʻa ke kumukūʻai o ka lignin, a he mau hana like ʻole ka lignin a me kāna mau derivatives, hiki ke hoʻohana ʻia e like me nā dispersants, adsorbents/desorbers, petroleum recovery aid, a me asphalt emulsifiers. ʻO ka haʻawina koʻikoʻi o ka lignin i ka hoʻomohala hoʻomau ʻana o ke kanaka aia ma ka hoʻolako ʻana i kahi kumu paʻa a hoʻomau o ka mea olaola, a ākea loa kāna noi. E aʻo i ka pilina ma waena o nā waiwai lignin a me ka hana, a hoʻohana i ka lignin e hana i nā polymers hiki ke hoʻohaʻahaʻa a hiki ke hoʻololi ʻia. ʻO nā waiwai physicochemical, nā waiwai hana a me nā ʻenehana o ka lignin ua lilo i mea pale i ka noiʻi o kēia manawa e pili ana i ka lignin.

Hana ʻia ʻo Lignin sulfonate mai ka lāʻau sulfite pulp lignin maka ma o ka hoʻopaʻa ʻana, ka hoʻololi ʻana, ka oxidation, ka kānana a me ka maloʻo. ʻAʻole ʻo Chromium lignosulfonate wale nō ka hopena o ka hoʻohaʻahaʻa ʻana i ka wai, akā loaʻa pū kekahi hopena diluting. I ka manawa like, loaʻa iā ia nā hiʻohiʻona o ka paʻakai paʻakai, ke kiʻekiʻe o ka mahana a me ka hoʻohālikelike maikaʻi. He mea hoʻoheheʻe ia me ka paʻakai paʻakai ikaika, ka pale calcium a me ka pale wela. Hoʻohana nui ʻia nā huahana i loko o ka wai maʻemaʻe, ka wai kai, a me nā slurries sima paʻakai paʻakai, nā ʻōpala i mālama ʻia i ka calcium a me nā ʻōpala hohonu hohonu, hiki ke hoʻopaʻa pono i ka pā punawai a hoʻemi i ka viscosity a me ka shear o ka lepo.

Nā hōʻailona kino a me nā kemika o ka lignosulfonate:

1. ʻAʻole i loli ka hana ma 150 ~ 160 ℃ no nā hola 16;

2. ʻOi aku ka maikaʻi o ka hana o ka 2% paʻakai sima slurry ma mua o ka hao-chromium lignosulfonate;

3. Loaʻa iā ia ka mana anti-electrolyte ikaika a kūpono i nā ʻano lepo āpau.

Hoʻopili ʻia kēia huahana i loko o kahi ʻeke i ulana ʻia me kahi ʻeke plastik, me kahi paona paona o 25 kg, a ua hōʻailona ʻia ka ʻeke ʻeke me ka inoa huahana, hōʻailona kūʻai, kaumaha huahana, mea hana a me nā huaʻōlelo ʻē aʻe. Pono e mālama ʻia nā huahana i loko o ka hale kūʻai e pale ai i ka makū.
