Qhov yooj yim tivthaiv ntawmSodium Lignosulfonateyog benzyl propane derivative. Cov pab pawg sulfonic acid txiav txim siab tias nws muaj cov dej solubility zoo, tab sis nws yog insoluble hauv ethanol, acetone thiab lwm yam kuab tshuaj organic. Raug Soundwood Lignosulfonate tuaj yeem qhia tawm los ntawm cov tshuaj lom neeg hauv qab no C9H8.5o2.5 (OC3) 0.55 (li3h) 0.4.
Cov qauv kev coj ua thiab cov roj ntsha hnyav ntawm Lignosulfonate txiav txim siab tias nws txawv ntawm lwm cov hluavtaws surfactants hauv ntau yam. Nws muaj cov khoom hauv lub cev hauv qab no thiab tshuaj lom neeg:
1.Qhov Degive Stortosulfonate Molecule muaj ntau pab pawg hydrophilic muaj zog heev, thiab nws tsis tuaj yeem muaj cov theem zoo nkauj sib txuas lus zoo li qub Tsawg molecular surfactants. Yog li ntawd, txawm tias nws tuaj yeem txo cov nro hauv kev daws, nws muaj kev tswj me me rau saum npoo nro thiab yuav tsis ua Micelles.
2.Qhov viscosity ntawm cov slurry tuaj yeem txo los ntawm kev ntxiv ib qho me me ntawm Lignosulfonate rau hauv viscous slurry los ntawm adsorption thiab dispersion; Thaum ntxiv rau kev ncua kev ncua rov qab, kev nrawm nrawm ntawm cov khoom raug tshem tawm tuaj yeem raug txo kom tsawg. Qhov no yog vim tias Lignosulfonate tau muaj zog hydrophilicity thiab electronegativity. Nws tsim cov pawg anionic hauv cov tshuaj aqueous. Thaum nws yog adsorbed ntawm ntau cov organic lossis inorganic cov lus, cov hais kom ruaj khov rau lub xeev ruaj khov vim yog kev sib nrig sib cais ntawm cov pab pawg anionic. Qee qhov kev tshawb fawb kuj qhia tau tias cov adsorption thiab lubrication ntawm microscuptatic yog qhov sib txawv ntawm cov kab mob me me nrog nws cov roj ntsha sib txawv thiab raug ncua System. Feem ntau, cov leb feem nrog molecular hnyav li 5000 txog 40,000 muaj cov nyhuv zoo dua.
3.Qhia Lignosulfonate muaj ntau dua phenol hydroxyl, cov pab pawg carbonyl thiab carboryl thiab carbon chelates ntawm ligrin, yog li muaj cov yam ntxwv tshiab Cov. Piv txwv li, chelation ntawm lignosulfonate nrog hlau ion, chromium ion, thiab lwm yam tseem yuav ua rau nws muaj qee yam kev cuam tshuam thiab txwv tsis pub ua tus neeg saib xyuas dej.
4.Qhov muaj nuj nqi nyob hauv cov nroj tsuag ntuj. Zoo li cov nplaum, cov npe tau faib nyob ib ncig ntawm cov fiber ntau thiab nruab nrab ntawm cov fiber, inlaid nrog cov fibers thiab cov qauv me, ua rau nws muaj zog pob txha pob txha pob txha muaj zog. Qhov laj thawj yog vim li cas cov ntoo tsis tuaj yeem poob rau kaum tawm ntawm metres lossis ntau pua ntawm meters yog vim tias cov nplaum ntawm lignin. Lignosulfonate sib cais los ntawm cov cawv dub tuaj yeem hloov kho kom rov qab ua cov dej cawv thawj, thiab nws cov piam thaj hauv cov dej cawv uas tuaj yeem pab txhim kho lawv cov txiaj ntsig adhesive los ntawm kev sib nrig sib kho.
5.Foaming kev ua npuas ncauj ua yeeb yam ntawm Lignosulfonate yog qhov zoo sib xws, tab sis kev ua npuas ncauj ntawm cov khoom siv ua npuas dej tsis muaj txiaj ntsig, thiab ua npuas dej zoo ntawm lub chaw ua npuas dej yuav muaj qee yam cuam tshuam rau nws daim ntawv thov kev ua tau zoo. Piv txwv li, thaum nws tau siv los ua cov pob zeb ua vaj tse, ntawm ib sab ntawm cov pob zeb tsim los ntawm pob zeb ua kom muaj zog ntxiv thiab ua haujlwm yuav ua tau zoo dua qub; Ntawm qhov tod tes, cov cuab yeej ua npuas ncauj yuav nce ntxiv huab cua nkag thiab txo lub zog ntawm cov pob zeb. Thaum siv los ua huab cua entraining dej txo tus neeg sawv cev, nws tau txais txiaj ntsig zoo los txhim kho lub zog ua kom tsis kam thiab ruaj khov ntawm cov pob zeb.
