Sodium bentonite raug faib raws li hom thiab cov ntsiab lus ntawm cov cations pauv tau ntawm cov txheej ntawm montmorillonite: ib qho nrog alkalinity coefficient ntau dua lossis sib npaug rau 1 yog sodium bentonite, thiab ib qho nrog alkalinity coefficient tsawg dua 1 yog calcium bentonite.

Qhov kub tsis ua haujlwm ntawm cov khoom siv sodium bentonite txawv vim muaj ntau yam sodium, tab sis lawv txhua tus qis dua li ntawm cov khoom siv sodium bentonite ntuj; lub zog nthuav dav ntawm cov khoom siv sodium bentonite ntuj yog loj dua li ntawm cov khoom siv sodium bentonite; qhov kev txiav txim c-axis ntawm cov khoom siv sodium bentonite ntuj yog siab dua li ntawm cov khoom siv sodium bentonite, nrog cov noob zoo dua thiab muaj zog dispersion. Cov khoom siv lub cev thiab tshuaj lom neeg thiab cov khoom siv thev naus laus zis ntawm Na bentonite zoo dua li ntawm Ca bentonite. Nws yog feem ntau pom tseeb hauv: kev nqus dej qeeb, kev nqus dej siab thiab qhov piv nthuav dav; muaj peev xwm pauv cation siab; kev sib kis zoo hauv dej nruab nrab, tus nqi colloidal siab; thixotropy zoo, viscosity, lubricity, pH tus nqi; thermal stability zoo; plasticity siab thiab adhesion muaj zog; kub kub ntub tensile zog thiab qhuav siab zog. Yog li ntawd, tus nqi siv thiab tus nqi kev lag luam ntawm sodium bentonite siab dua. Cov khoom siv lub cev thiab tshuaj lom neeg ntawm cov khoom siv sodium bentonite tsis yog nyob ntawm hom thiab cov ntsiab lus ntawm montmorillonite xwb, tab sis kuj nyob ntawm txoj kev thiab qib ntawm cov khoom siv sodium.

1. Thaum lub qhov dej khawb, cov av nkos uas muaj cov kua dej ntau thiab thixotropy raug teeb tsa.
2. Hauv kev tsim khoom siv tshuab, nws tuaj yeem siv ua xuab zeb molding thiab binder, uas tuaj yeem kov yeej qhov xwm txheej ntawm "xuab zeb suav nrog" thiab "peeling" ntawm castings, txo qhov seem ntawm castings, thiab xyuas kom meej qhov tseeb thiab du ntawm castings.
3. Siv ua cov ntawv sau rau hauv kev lag luam ntawv los txhim kho qhov ci ntawm cov ntawv ntawv.
4. Nws siv tau ua txheej tiv thaiv hluav taws xob es tsis txhob siv cov hmoov txhuv nplej siab thiab luam ntawv txheej hauv kev luam ntawv thiab kua zas xim.
5. Hauv kev lag luam hlau, bentonite yog siv los ua tus binder ntawm hlau ore pellet, uas ua rau qhov loj me ntawm cov hlau sib xws thiab kev txo qis kev ua tau zoo, uas yog kev siv bentonite loj tshaj plaws.
6. Hauv kev lag luam roj av, sodium bentonite yog siv los npaj cov dej emulsion.
7. Hauv kev lag luam zaub mov, sodium bentonite yog siv los tshem tawm thiab ntxuav cov roj tsiaj thiab zaub, ua kom cov cawv txiv hmab thiab kua txiv hmab txiv ntoo meej, tswj cov npias, thiab lwm yam.
8. Hauv kev lag luam luam ntawv thiab zas xim, sodium bentonite yog siv los ua cov khoom sau, cov tshuaj dawb, cov tshuaj tiv thaiv antistatic, uas tuaj yeem hloov cov hmoov txhuv nplej siab thiab ua cov tshuaj luam ntawv.
9. Nws kuj tseem tuaj yeem yog cov khoom noj khoom haus ntxiv.
