Cov Qauv Grout Pobzeb yog dab tsi?

Cov pob zeb grout yog ib yam khoom siv hauv kev teeb tsa pobzeb los sau cov qhov sib txawv lossis cov pob qij txha ntawm cov pobzeb ib leeg.

Feem ntau cov grout pobzeb yuav tsum sib xyaw nrog dej kom ua ib yam li nplaum thiab siv cov roj hmab ntab los nplaum rau cov pob qij txha ntawm cov pobzeb. Tom qab siv cov grout lawm, cov grout seem yuav raug so tawm ntawm cov pobzeb, thiab ntxuav qhov chaw kom huv si thiab sib npaug ntawm cov pobzeb.

Cov mis mos rau cov vuas pobzeb uas muaj HPMC (Hydroxypropyl Methylcellulose) thiab RDP (Redispersible Polymer Hmoov) yuav xav tau kev piav qhia ntxiv txog cov tshuaj ntxiv no, lawv cov haujlwm, thiab lawv cov kev sib cuam tshuam hauv cov mis mos. Hauv qab no yog cov mis mos rau cov vuas pobzeb nrog rau cov lus piav qhia thiab cov ntaub ntawv ntxiv.

Cov Qauv Qhia Txog Pobzeb Grout yog raws li hauv qab no

Cov Lus Piav Qhia Txog Cov Qauv Pobzeb Grout

1. Cov cement Portland:

- Qhov ntau: 1 feem los ntawm qhov ntim

- Kev Ua Haujlwm: Portland cement ua haujlwm ua tus thawj coj hauv cov grout sib tov, muab cov qauv muaj zog thiab ruaj khov.

2. Xuab zeb zoo:

- Qhov ntau: 2 feem los ntawm qhov ntim

- Kev Ua Haujlwm: Cov xuab zeb zoo ua haujlwm ua cov khoom ntim, pab txhawb rau cov grout sib xyaw, txhim kho kev sib xws, thiab tiv thaiv kev ntsws thaum lub sijhawm ziab.

3. Dej:

- Qhov ntau: 0.5 txog 0.6 feem los ntawm qhov ntim

- Kev Ua Haujlwm: Dej ua rau cov cement ua haujlwm thiab ua rau cov grout sib xyaw ua haujlwm tau. Qhov ntau npaum li cas ntawm cov dej xav tau nyob ntawm seb qhov chaw ib puag ncig zoo li cas thiab qhov sib xws xav tau.

4. HPMC (Hydroxypropyl Methylcellulose):

- Qhov ntau: Txawv

- Kev Ua Haujlwm: HPMC yog cov polymer ua los ntawm cellulose uas siv rau hauv cov grout kom khaws dej. Nws ua rau kev ua haujlwm yooj yim dua los ntawm kev ua kom qeeb qeeb ntawm cov txheej txheem ziab, ua rau kev siv tau zoo dua thiab txo qhov tawg.

5. RDP (Hmoov Polymer Uas Rov Qab Faib Tau):

- Qhov ntau: Txawv

- Kev Ua Haujlwm: RDP yog hmoov polymer uas ua rau cov grout yooj ywm, lo rau cov vuas, thiab ua kom ruaj khov. Nws kuj tseem ua rau nws tiv taus dej, txo qhov muaj feem yuav dej nkag mus.

6. Cov Xim Xim (xaiv tau):

- Qhov ntau: Txawv

- Kev Ua Haujlwm: Cov xim pigments raug ntxiv rau lub hom phiaj zoo nkauj thaum tsim cov grout xim, muab ntau yam kev xaiv rau kev sib phim lossis sib piv nrog cov vuas.

# Cov Lus Qhia Ntxiv

- Cov Lus Qhia Sib Tov: Thaum tsim cov grout nrog HPMC thiab RDP, sib tov cov Portland cement thiab cov xuab zeb zoo ua ntej. Maj mam ntxiv dej thaum do. Tom qab ua tiav qhov sib tov sib xws, ntxiv HPMC thiab RDP, kom ntseeg tau tias muaj kev faib sib npaug. Qhov ntau npaum li cas ntawm HPMC thiab RDP yuav txawv raws li cov khoom thiab cov lus pom zoo ntawm cov chaw tsim khoom.

Cov txiaj ntsig ntawm HPMC thiab RDP:

- HPMC txhim kho qhov sib xws thiab ua haujlwm tau ntawm cov grout, ua rau nws yooj yim dua rau kev thov thiab txo qhov kev pheej hmoo ntawm kev tawg.

- RDP ua rau muaj kev ywj pheej, kev nplaum, thiab kev ruaj khov tag nrho. Nws muaj txiaj ntsig zoo rau cov grout hauv thaj chaw muaj neeg coob lossis cov chaw uas raug dej noo.

- Kev Kho Cov Qauv Grout: Cov qauv grout yuav xav tau kev kho raws li cov yam xws li av noo, kub, thiab cov kev cai siv tshwj xeeb. Kev kho cov qauv kom haum rau qhov xav tau ntawm qhov project yog qhov tseem ceeb.

- Kev Kho thiab Ziab: Tom qab siv cov grout, cia nws kho rau lub sijhawm pom zoo kom ua tiav qhov muaj zog thiab ua tau zoo tshaj plaws. Lub sijhawm kho yuav txawv nyob ntawm qhov xwm txheej ib puag ncig.

- Kev Ceev Faj Txog Kev Nyab Xeeb: Thaum ua haujlwm nrog cov khoom siv cement thiab cov khoom ntxiv xws li HPMC thiab RDP, ib txwm ua raws li cov lus qhia kev nyab xeeb, suav nrog kev hnav cov khoom siv tiv thaiv xws li hnab looj tes thiab lub ntsej muag kom tsis txhob ua pa plua plav thiab kov daim tawv nqaij.

- Sab lajChaw Tsim Khoom HPMCCov Lus Qhia: Nws yog ib qho tseem ceeb kom ua raws li cov lus qhia ntawm cov chaw tsim khoom rau cov khoom siv grout tshwj xeeb uas koj siv, vim tias cov qauv, cov piv sib tov, thiab cov txheej txheem thov tuaj yeem sib txawv ntawm cov hom.
