Lignin yog thib ob tsuas yog rau cellulose hauv ntuj tshwj tseg, thiab yog tau tsim dua ntawm tus nqi ntawm 50 billion tons txhua xyoo. Lub pulp thiab daim ntawv kev lag luam cais tawm ntawm 140 lab tons ntawm cov nroj tsuag, thiab tau txais ntawm Lignin los yog tseem ncaj qha tawm mus rau hauv dej lossis dej ntws ib yam li " Dej cawv dub ". Tom qab tau mloog zoo, nws yog hlawv thiab tsis tshua muaj siv tau zoo. Qhov nce zuj zus ntawm cov pob zeb hluav taws xob ntawm pob zeb lub zog, muaj ntau txoj kev loj hlob ntawm Lignin Science paub txog kev txhim kho kev lag luam ntawm cov txiaj ntsig kev lag luam ntawm Lignin.

Tus nqi ntawm Lignin yog tsawg, thiab nws lub derivatives muaj ntau yam kev ua haujlwm tsis zoo, uas tuaj yeem siv ntau yam kev pab cuam, thiab asphalt emulsifiers. Qhov tseem ceeb tshaj plaws ntawm Lignin rau tib neeg kev txhim kho kev loj hlob nyob hauv muab cov teeb meem ruaj khov thiab txuas ntxiv ntawm cov organic teeb meem, thiab nws cov ntawv thov kev cia siab yog qhov dav heev. Kawm cov kev sib raug zoo ntawm Lignin Proderties thiab cov qauv, thiab siv Lignin los ua kom cov tsis ncaj ncees thiab cov neeg ua haujlwm polymers. Cov khoom siv dag zog, ua cov khoom thiab thev naus laus zis ntawm lignin tau ua cov teeb meem rau cov kev tshawb fawb tam sim no ntawm Lignin.

Lignin sulfonate yog tsim los ntawm sulfite ntoo pulp lamping cov ntaub ntawv los ntawm cov khoom siv, hloov, oxidation, pom thiab ziab. Chromium Lignosulfonate tsis tsuas muaj cov nyhuv ntawm txo cov dej poob, tab sis kuj tau diluting nyhuv. Nyob rau tib lub sijhawm, nws kuj tseem muaj cov yam ntxwv ntawm ntsev tsis kam, muaj kub ua tsis kam thiab muaj kev sib haum zoo. Nws yog deetrent nrog muaj zog ntsev kuj, calcium ua rau thiab qhov kub kuj tsis kam. Cov khoom yog siv dav hauv dej tsis qab, dej hiav txwv, thiab cov av nkos zoo nkauj thiab txo cov av viscium thiab txo cov viscosity thiab shear ntawm cov av nkos.

Kev siv lub cev thiab tshuaj lom neeg ntawm Lignosulfonate:

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

2. Cov kev ua tau zoo ntawm 2% Ntsev Ntsoov Slurry yog zoo dua li ntawm Hlau-Chromium Lignosulfonate;

3. Nws muaj zog tiv thaiv hluav taws xob hauv electrolyte thiab haum rau txhua hom av.

Cov khoom no tau ntim rau hauv lub hnab ntim khoom siv nrog lub hnab yas, nrog lub hnab ntim khoom, cov cim lag luam, cov khoom lag luam thiab lwm yam lus. Cov khoom lag luam yuav tsum tau muab cia rau hauv lub tsev rau khoom kom tiv thaiv noo noo.
