Puas yog Sodium Lignosulfonate Soluble hauv dej?
Sodium lignosulfonate yog daj xim av hmoov tag nrho cov dej soluble, nws yog ib txwm anionic surfactant ntawm siab molecular polymer, nplua nuj nyob rau hauv sulfo thiab carboxyl pawg muaj dej-solubility, surf-activity thiab dispersion muaj peev xwm.
Cov kev siv ntawm Sodium Lignosulfonates:
1.Dispersant rau qhob additives
2.Plastifying additive rau cib thiab ceramics
3. Tanning tus neeg sawv cev
4.Deflocculant
5.Bonding tus neeg sawv cev rau fiberboards
6.Binding tus neeg sawv cev rau molding pellets, carbon dub, chiv, activated carbon, foundry pwm
7.Dust txo tus neeg sawv cev thaum lub sij hawm txau rau txoj kev uas tsis yog asphalted thiab dispersion nyob rau hauv kev ua liaj ua teb.
Lignin thiab Environment:
Lignins tau siv ntau xyoo rau ntawm txoj kev, hauv kev tsim tshuaj tua kab, hauv tsiaj pub tsiaj, thiab lwm yam khoom uas tiv tauj cov zaub mov.Raws li qhov tshwm sim, cov tuam txhab lag luam lignin tau ua ntau yam kev tshawb fawb los kuaj lignin qhov cuam tshuam rau ib puag ncig.Cov txiaj ntsig tau pom tias lignins muaj kev nyab xeeb rau ib puag ncig thiab tsis muaj teeb meem rau cov nroj tsuag, tsiaj txhu, thiab dej hauv dej thaum tsim khoom thiab siv tau zoo.
Nyob rau hauv cov txheej txheem ntawm pulp mills, cellulose yog cais los ntawm lignin thiab rov qab los siv rau ntau yam khoom sib txawv.Lignosulfonate, ib qho khoom lag luam lignin rov qab los ntawm cov txheej txheem sulfite pulping, yog qhov txaus siab tshwj xeeb los txiav txim siab txog teeb meem ib puag ncig.Nws tau siv los ua kev kho mob rau txoj kev av hauv Tebchaws Europe thiab North America txij li xyoo 1920.Kev tshawb fawb dav dav thiab kev siv keeb kwm ntawm cov khoom no yam tsis tau tshaj tawm cov lus tsis txaus siab ntawm cov nroj tsuag puas lossis teeb meem loj txhawb qhov kev txiav txim siab tias lignosulfonates yog ib puag ncig zoo thiab tsis muaj tshuaj lom.
Hais txog peb:
Peb lub tuam txhab yog cov chaw tsim khoom tshwj xeeb hauv kev tsim khoom thiab muag khoom ntawm sodium lignosulfonate, nrog tus nqi tsim nyog thiab txhim khu kev qha zoo;lub tuam txhab muaj cov cuab yeej zoo tshaj plaws thiab cov qauv kev tswj hwm qib siab, thiab tau tsim kom muaj kev ruaj ntseg thiab kev sib raug zoo nrog ntau tus neeg muas zaub hauv tsev thiab txawv teb chaws.
