Cov iav dej yog siv los ua ib qho kev sib khi rau cov khoom siv tsis zoo.Kuj tseem hu ua pyrophorine.Xws li alkali hlau silicates yog tsim los ntawm melting cov tshuaj tiv thaiv ntawm quartz xuab zeb nrog sodium, los yog poov tshuaj, los yog lithium carbonate (los yog sulfate).Nws cov qauv tshuaj yog R2O•nSiO2•mH2O, R2O hais txog alkali hlau oxides, xws li Na2O, K2O, Li2O;n hais txog tus naj npawb ntawm moles ntawm SiO2;m yog tus naj npawb ntawm moles ntawm H2O nws muaj.Cov alkali hlau silicates yaj nyob rau hauv dej thiab hydrolyze los ua sol.Lub sol muaj cov khoom zoo cementation.Yog li ntawd, nws yog dav siv raws li ib tug inorganic khoom binder nyob rau hauv kev lag luam, dav siv raws li ib tug daim ntawv cog lus nyob rau hauv lub refractory kev lag luam, thiab yog siv raws li ib tug cement pob zeb accelerator nyob rau hauv kev tsim kho, thiab kuj lug siv nyob rau hauv papermaking thiab textile industries.Kev txhim kho kev taw qhia thiab kev cia siab ntawm sodium silicate chemical grouting cov ntaub ntawv:
① Chemical grouting cov ntaub ntawv yog tsuas yog siv nyob rau hauv underground engineering, thiab underground ib puag ncig yog complex thiab hloov tau, uas yuav tsum tau kev tsim kho ntawm ntau hom dej iav slurry cov ntaub ntawv uas muaj kev ua tau zoo raws li qhov sib txawv underground ib puag ncig.
Ib qho ntawm cov ntsiab lus tseem ceeb ntawm txoj kev tshawb fawb tshiab ntawm sodium silicate slurry yog tias tus neeg sawv cev tseem ceeb ntawm sodium silicate slurry yuav tsis ua rau muaj teeb meem ib puag ncig ntxiv rau kev ua kom muaj kuab lom, yog li thaum xaiv cov khoom siv ntxiv, nws yog ib qho tsim nyog los txiav txim siab seb nws puas muaj kuab lom, tshuaj lom. ua ntej siv cov slurry, los yog tshuaj lom thaum siv, los yog tshuaj lom tom qab ua tiav ntawm qhov project.Nrhiav tsis muaj tshuaj lom sodium silicate additives yog txoj kev loj hlob ntawm tshiab sodium silicate slurry cov ntaub ntawv.
③ Cov khoom siv iav dej ua cov khoom siv tshuaj lom neeg muaj keeb kwm ntev ntawm kev siv, tab sis nws cov ntsiab lus ruaj khov txog tam sim no, tseem tsis tau muaj cov lus qhia zoo ib yam, los tsim cov khoom siv iav dej tshiab, nws yog ib qho tsim nyog yuav tsum tau ua qhov kev tshawb fawb tob. ntawm dej iav gel mechanism.
(4) Lub polymerization thiab curing txheej txheem ntawm sodium silicate slurry yog ib tug complex txheej txheem, thiab tsuas yog los ntawm thawj zaug nkag siab lub hauv paus ntsiab lus ntawm cement consolidation peb yuav muab lub hauv paus rau kev kawm lub sij hawm gelation ntawm sodium silicate slurry.
Piv nrog rau lwm cov tshuaj grouting cov ntaub ntawv, qhov zoo tshaj plaws ntawm sodium silicate slurry yog tus nqi qis, thiab qhov tsis zoo yog tias nws lub zog sib koom ua ke tsis zoo li qee cov tshuaj slurry, yog li lub zog ntawm sodium silicate slurry los tshawb txog lub peev xwm, kuj yog ib qho zoo heev. yav tom ntej kev taw qhia ntawm kev siv zog.
Daim ntawv thov ntawm sodium silicate slurry yog tam sim no feem ntau txwv rau cov haujlwm ib ntus lossis ib nrab mus tas li, vim tias kev tshawb fawb hauv kev ua haujlwm yuav tsum muaj qhov tob.
Cov txheej txheem kev txhim kho ntawm cov iav dej hloov pauv, los ntawm ib qho kev hloov pauv mus rau kev txhim kho kev sib xyaw ua ke, qhov kev sim ua pov thawj tias kev siv cov khoom siv sib xyaw ua ke ntau dua li ib qho kev hloov kho feem ntau muaj kev ua tau zoo dua.
