Lub formulation ntawm qhuav mix mortar yog dab tsi?

Qhuav mix mortar yog ib hom kev tsim khoom siv los khi ua ke ntau yam xws li cement, xuab zeb, thiab lwm yam khoom ntxiv. Nws yog feem ntau siv rau hauv kev tsim cov phab ntsa, pem teb, thiab lwm yam qauv. Qhuav mix mortar yog ib qho yooj yim thiab siv tau zoo rau ntau qhov kev tsim kho.

Lub formulation ntawm qhuav mix mortar yog ib tug complex txheej txheem uas muaj xws li kev xaiv ntawm cov khoom xyaw uas yog, kev sib xyaw kom zoo ntawm cov khoom, thiab kev siv ntawm cov tshuaj khib. Lub formulation ntawm qhuav mix mortar pib nrog kev xaiv ntawm cov khoom xyaw tsim nyog. Cov khoom xyaw feem ntau siv hauv cov khoom sib xyaw qhuav yog cov cement, xuab zeb, thiab lwm yam khoom ntxiv. Kev xaiv ntawm cov khoom xyaw no nyob ntawm hom phiaj xwm thiab cov khoom xav tau ntawm cov tshuaj khib.

Formulation of Dry mixed Mortar raws li hauv qab no:

HPMC (300 viscosity), tsawg viscosity thiab siab dej tuav hom, tshauv cov ntsiab lus tsawg dua 5, dej tuav 95% +

 

5. Heavy gypsum mortar formulation
Gypsum hmoov (thaum pib 6 feeb): 300kg

Dej ntxuav xuab zeb: 650kg

Talc hmoov: 50kg

Gypsum retarder: 0.8kg

HPMC8-100,000 nplaum: 1.5kg

Thixotropic lubricant: 0.5kg

Lub sijhawm ua haujlwm yog 50-60 feeb, tus nqi tuav dej yog 96%, thiab lub teb chaws tus qauv dej tuav tus nqi yog 75%

 

6. High-strength pobzeb grout formulation
42.5 cement: 450 kg

Tus neeg sawv cev nthuav dav: 32kg

Quartz xuab zeb 20-60 mesh: 450kg

Ntxuav xuab zeb 70-130 mesh: 100kg

Polyxiang acid alkali dej tus neeg sawv cev: 2.5kg

HPMC (tsis tshua muaj viscosity): 0.5kg

Antifoaming tus neeg sawv cev: 1kg

nruj me ntsis tswj cov dej ntxiv, 12-13%, ntau dua yuav cuam tshuam rau hardness

 

7. Polymer rwb thaiv tsev mortar formulation
42.5 Cement: 400 Kg

Ntxuav xuab zeb 60-120 mesh: 600kg

Latex hmoov: 12-15kg

Qhov hnyav: 2-3 kg

Ntoo fiber ntau: 2-3kg

 

Thaum cov khoom xyaw tau raug xaiv, lawv yuav tsum tau muab sib xyaw kom zoo. Qhov no yog ua los ntawm thawj combining cov khoom xyaw qhuav nyob rau hauv ib tug tov khoom. Tom qab ntawd cov khoom xyaw yog tov kom txog thaum lawv tsim ib homogeneous sib tov. Tom qab ntawd cov sib tov yog poured rau hauv ib lub thawv thiab sab laug mus teem.

Thaum sib tov tau teem, nws yog npaj txhij mus thov rau saum npoo. Qhov no yog ua los ntawm kev siv lub trowel los yog lwm yam cuab yeej los kis tus mortar sib npaug ntawm qhov chaw. Lub mortar yuav tsum tau siv rau hauv cov txheej nyias nyias thiab tso cai kom qhuav ua ntej txheej tom ntej yog siv.

Cov kauj ruam kawg nyob rau hauv formulation ntawm qhuav mix mortar yog cov txheej txheem curing. Qhov no yog ua los ntawm kev cia lub mortar kom qhuav tag ua ntej nws yuav raug ya raws. Qhov no yuav pab kom ntseeg tau tias lub mortar muaj qhov xav tau lub zog thiab kav ntev.

Lub formulation ntawm qhuav mix mortar yog ib qho tseem ceeb ntawm txhua qhov kev tsim kho. Nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom xyaw kom raug, sib tov kom raug, thiab siv lub mortar kom raug thiaj li yuav ua tiav qhov project. Los ntawm kev ua raws li cov kauj ruam uas tau teev tseg saum toj no, koj tuaj yeem xyuas kom meej tias koj qhov project yuav ua tiav thiab cov mortar yuav kav ntev mus rau xyoo tom ntej.
