Lignin yog thib ob tsuas yog cellulose nyob rau hauv natural reserves, thiab yog regenerated ntawm tus nqi ntawm 50 billion tons txhua txhua xyoo. Kev lag luam pulp thiab ntawv sib cais txog 140 lab tons ntawm cellulose los ntawm cov nroj tsuag txhua xyoo, thiab tau txais txog 50 lab tons ntawm lignin los ntawm cov khoom, tab sis txog tam sim no, ntau dua 95% ntawm lignin tseem ncaj qha tawm mus rau hauv dej los yog dej ntws raws li " dej cawv dub". Tom qab tau concentrated, nws yog hlawv thiab tsis tshua siv tau zoo. Qhov nce ntxiv ntawm cov fossil zog, ntau reserves ntawm lignin, thiab kev loj hlob sai ntawm lignin science txiav txim siab kev loj hlob ntawm kev lag luam ntawm lignin.

Tus nqi ntawm lignin yog tsawg, thiab lignin thiab nws cov derivatives muaj ntau yam functionalities, uas yuav siv tau raws li dispersants, adsorbents / desorbers, roj av rov pab, thiab asphalt emulsifiers. Qhov tseem ceeb tshaj plaws ntawm lignin rau tib neeg kev txhim kho kom ruaj khov yog nyob rau hauv Muab qhov chaw ruaj khov thiab txuas ntxiv ntawm cov organic teeb meem, thiab nws daim ntawv thov kev cia siab yog dav heev. Kawm txog kev sib raug zoo ntawm lignin zog thiab cov qauv, thiab siv lignin los ua cov polymers degradable thiab tauj dua tshiab. Lub zog physicochemical, kev ua haujlwm thiab kev siv tshuab ntawm lignin tau dhau los ua teeb meem rau kev tshawb fawb tam sim no ntawm lignin.

Lignin sulfonate yog tsim los ntawm sulfite ntoo pulp lignin raw khoom los ntawm concentration, hloov, oxidation, pom thiab ziab. Chromium lignosulfonate tsis tsuas yog txo cov dej poob, tab sis kuj muaj cov nyhuv diluting. Nyob rau tib lub sij hawm, nws kuj muaj cov yam ntxwv ntawm ntsev tsis kam, siab kub kuj thiab zoo compatibility. Nws yog diluent nrog muaj zog ntsev tsis kam, calcium tsis kam thiab kub tsis kam. Cov khoom siv dav siv hauv cov dej tsis qab, dej hiav txwv, thiab cov ntsev ntsev cov cement slurries, ntau yam calcium-kho av nkos thiab ultra-dub zoo av nkos, uas tuaj yeem txhim kho cov phab ntsa zoo thiab txo cov viscosity thiab shear ntawm cov av nkos.

Lub cev thiab tshuaj ntsuas ntawm lignosulfonate:

1. Qhov kev ua tau zoo tseem tsis hloov pauv ntawm 150 ~ 160 ℃ rau 16 teev;

2. Kev ua tau zoo ntawm 2% ntsev cement slurry zoo dua li ntawm cov hlau-chromium lignosulfonate;

3. Nws muaj peev xwm tiv thaiv electrolyte thiab haum rau txhua yam av nkos.

Cov khoom no yog ntim rau hauv ib lub hnab woven lined nrog ib lub hnab yas, nrog lub ntim hnyav ntawm 25 kg, thiab lub hnab ntim tau cim nrog cov khoom npe, cov cim lag luam, cov khoom hnyav, cov chaw tsim khoom thiab lwm cov lus. Cov khoom yuav tsum tau muab cia rau hauv lub warehouse kom tsis txhob ya raws.
