Dej iav

Lub modulus ntawm waterglass tov, tseem hu ua sodium silicate tov los yog sodium silicate, yog ib qho tseem ceeb parameter los piav txog cov yam ntxwv ntawm cov tshuaj. Modulus feem ntau txhais tau tias yog cov molar piv ntawm silicon dioxide (SiO₂) thiab alkali hlau oxides (xws li sodium oxide Na₂O lossis potassium oxide K₂O) hauv dej iav, uas yog, m (SiO₂) / m (M₂O), qhov twg M sawv cev rau alkali. hlau ntsiab (xws li Na, K, thiab lwm yam).

Ua ntej, cov modulus ntawm cov kua dej iav muaj qhov cuam tshuam loj rau nws cov khoom thiab kev siv. Waterglass daws nrog qis modulus feem ntau muaj cov dej solubility zoo dua thiab qis dua viscosity, thiab tsim nyog rau qee qhov kev thov uas xav tau kom muaj dej zoo. Waterglass daws nrog ntau dua modulus muaj ntau dua viscosity thiab muaj zog adhesion, thiab yog haum rau lub sij hawm uas yuav tsum tau ntau zog thiab hardness.
Qhov thib ob, lub modulus ntawm waterglass tov yog feem ntau ntawm 1.5 thiab 3.5. Lub modulus nyob rau hauv qhov ntau yog suav tias yog qhov tsim nyog tshaj plaws rau kev tsim khoom thiab kev siv, vim tias nws tuaj yeem ua kom ntseeg tau tias cov dej iav dej muaj qee yam solubility thiab fluidity, thiab tuaj yeem muab cov adhesion txaus thiab lub zog.
Thib peb, lub modulus ntawm cov iav dej tsis kho, nws tuaj yeem tswj tau los ntawm kev kho cov khoom siv raw thiab cov txheej txheem ntau lawm. Yog li ntawd, nyob rau hauv ntau daim ntawv thov scenarios, dej iav tov nrog tsim nyog modulus tuaj yeem xaiv raws li cov kev xav tau tshwj xeeb.
Plaub, lub modulus ntawm dej iav kua kuj yog ze ze rau nws cov concentration, kub thiab lwm yam. Feem ntau hais lus, nrog rau qhov nce ntawm concentration thiab qhov txo qis ntawm qhov kub thiab txias, lub modulus ntawm cov iav dej yuav kuj nce raws li. Txawm li cas los xij, qhov kev hloov pauv no tsis yog linear, tab sis cuam tshuam los ntawm ntau yam.
Thib tsib, lub modulus ntawm cov iav dej yog qhov tseem ceeb rau kev piav qhia nws cov yam ntxwv, uas muaj kev cuam tshuam loj rau nws cov khoom thiab kev siv. Hauv kev siv tswv yim, nws yog ib qho tsim nyog los xaiv cov iav dej nrog cov qauv tsim nyog raws li cov kev xav tau tshwj xeeb.
Qhov concentration ntawm cov iav dej yog ib qho tseem ceeb parameter uas cuam tshuam rau cov khoom thiab daim ntawv thov los ntawm cov iav dej. Qhov concentration ntawm cov iav dej feem ntau yog qhia raws li qhov loj ntawm sodium silicate (Na₂SiO₃).

1. Feem ntau ntawm cov iav dej concentration

1. General concentration: Qhov concentration ntawm cov iav dej yog feem ntau 40%. Qhov concentration ntawm cov iav dej no muaj ntau dua hauv engineering, thiab nws qhov ceev yog feem ntau 1.36 ~ 1.4g / cm³.
2. Lub teb chaws tus qauv concentration: Raws li "GB / T 4209-2014" tus qauv, lub teb chaws tus qauv concentration ntawm dej iav yog 10% ~ 12%. Qhov no txhais tau hais tias qhov loj feem ntawm cov iav dej yuav tsum tau tswj nyob rau hauv qhov ntau.

2. Yam cuam tshuam rau qhov concentration ntawm cov iav dej

Qhov concentration ntawm cov iav dej yog cuam tshuam los ntawm ntau yam, suav nrog tab sis tsis txwv rau cov hauv qab no:

1. Qhov zoo ntawm cov iav dej: Qhov zoo ntawm cov ntaub ntawv raw khoom txiav txim siab qhov zoo ntawm cov iav dej uas tsim. Qhov zoo ntawm cov iav dej zoo, qhov siab dua qhov concentration.

2. Dej kub: Dej kub muaj qhov cuam tshuam ncaj qha rau ntawm cov iav dej dilution. Feem ntau hais lus, qhov siab dua cov dej kub, qhov qis dua qhov concentration.

3. Tus nqi ntawm cov dej ntxiv: Cov dej ntxiv ncaj qha cuam tshuam rau qhov concentration ntawm cov iav dej.

4. Lub sij hawm stirring: Yog tias lub sij hawm stirring luv luv, lub khob dej yuav tsis muaj sij hawm txaus los sib tov sib npaug nrog cov dej, uas yuav ua rau cov concentration tsis raug.

3. Cov txheej txheem ntawm kev nthuav qhia dej iav concentration

Ntxiv nrog rau kev qhia nws hauv pawg loj, qhov concentration ntawm cov iav dej kuj tuaj yeem qhia hauv qib Baume (°Bé). Baume yog ib txoj hauv kev qhia txog qhov concentration ntawm cov tshuaj, uas yog ntsuas los ntawm Baume hydrometer. Qhov concentration ntawm cov iav dej hauv cov ntaub ntawv grouting feem ntau yog qhia raws li 40-45Be, uas txhais tau hais tias nws Baume nyob rau hauv qhov ntau.

4. Cov lus xaus

Qhov concentration ntawm cov iav dej yog ib qho tseem ceeb parameter uas yuav tsum tau txiav txim siab raws li ib tug tshwj xeeb daim ntawv thov scenarios thiab xav tau kev pab. Hauv engineering thiab kev tsim khoom lag luam, qhov concentration ntawm cov iav dej yuav tsum tau tswj hwm kom ntseeg tau qhov zoo thiab ruaj khov ntawm cov khoom. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau them sai sai rau qhov cuam tshuam ntawm kev hloov pauv hauv cov iav dej concentration ntawm nws cov khoom thiab kev siv cov teebmeem.
