Lub luag haujlwm ntawm polycarboxylate superplasticizer hauv grouting mortars

Polycarboxylate superplasticizers (pces) yog cov dej ntws siab-txo cov neeg sawv cev siv hauv kev tsim kho. Lawv cov qauv tshuaj tshwj xeeb ua rau lawv ua tau zoo hauv kev txhim kho lub zog ua haujlwm thiab kev ua haujlwm ntawm cov ntaub ntawv grouting. Ntawm no yog tus cwj pwm tseem ceeb ntawm polycarboxylate superplasticizers nyob rau hauv grouting mortars:

1. Dej txo:

• Lub luag haujlwm: Cov haujlwm tseem ceeb ntawm polycarboxylate superplasticizers superplasticizers yog dej txo. Lawv muaj lub peev xwm los disperse Maas hais, cia kom muaj kev txo qis hauv dej cov ntsiab lus ntawm cov grout tsis muaj kev ua haujlwm. Qhov no ua rau muaj lub zog siab dua thiab cov kav dej ruaj khov ntawm cov khoom siv.

2. Txhim Kho Cov Haujlwm:

• Lub luag haujlwm: CCES txhim kho kev ua haujlwm ntawm cov txiv ntoo mortars los ntawm kev muab cov hluav taws kub siab thiab yooj yim ntawm kev tso chaw. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov uas cov grout yuav tsum nkag mus thiab sau qhov chaw nqaim lossis voids.

3. Cov ntshav sib cais thiab los ntshav:

• Lub luag haujlwm: Polycarboxylate superplasticizers pab txhawb kom txo qis cov kab mob cais thiab los ntshav ntau yam ntawm cov ntaub ntawv cog lus. Qhov no yog qhov tseem ceeb rau kev ua tiav cov kev xa tawm ntawm cov khib nyiab, tiv thaiv kev sib haum xeeb, thiab ua kom muaj kev sib hais haum zoo ib yam.

4. Txhim kho rhuaology:

• Lub luag haujlwm: pces tau hloov lub rheological cov khoom ntawm grouting mortars, cuam tshuam lawv ntws thiab viscosity. Qhov no tso cai rau kev tswj cov khoom zoo dua qub, kom ua raws li cov duab uas xav tau thiab ua rau muaj txiaj ntsig zoo.

5. Txhim Kho Cov Khoom Zoo:

• Lub luag haujlwm: Polycarboxylate superplasticizers superplasticizers pab txhawb kom cov khoom nplaum ntawm cov grout thiab lub substrate. Qhov no yog qhov tseem ceeb rau kev ua kom muaj kev sib cog lus zoo thiab tiv thaiv cov teeb meem xws li debonding lossis delamination.

6. Kev txhim kho lub zog ntxov:

• Lub luag haujlwm: Khij voj voog tuaj yeem txhawb kev txhim kho lub zog thaum ntxov lub zog hauv cov zaub tsib. Qhov no tau txais txiaj ntsig hauv cov ntawv thov uas tau txais kev teeb tsa nrawm thiab muaj zog, xws li nyob rau hauv prefast qhob ntsiab lus lossis cov txheej txheem kev txhim kho.

7. Sib txuas nrog cov quav ntxiv:

• Lub luag haujlwm: Polycarboxylate superplasticizers superplasticizers feem ntau tau tshaj lwm cov tshuaj ntxiv, xws li teeb tsa nrawm, rov ua haujlwm, thiab cov neeg sawv cev ua kom muaj huab cua. Qhov no tso cai rau kev yoog raws li cov khoom ntawm cov grout rau cov kev cai tshwj xeeb.

8. Kev cuam tshuam thiab cov kev cuam tshuam tsawg ib puag ncig:

• Lub luag haujlwm: pces paub rau lawv cov kev ua tau zoo hauv kev txo cov ntsiab lus hauv dej thaum khaws cov haujlwm ua haujlwm. Qhov no pab kom muaj kev nyab xeeb ntau dua thiab ib puag ncig kev tsim kho cov hlua khi tag nrho cuam tshuam nrog kev tsim khoom thiab kev thauj mus los ntawm xis mas.

9. High Flowility nyob rau hauv tus kheej-level grouts:

• Lub luag haujlwm: hauv kev siv nyiaj Grouts Level, Polycarboxylate superplasticizers yog qhov tseem ceeb rau kev ua tiav qhov kev xav tau zoo uas tsis muaj kev sib cais. Qhov no ua kom ntseeg tau tias cov grout tus kheej-qib thiab muab kev du, txawm tias saum npoo.

10. Txhim Kho Kom Raug:

Txiav txim siab:

• Kev siv tshuaj thiab kev sib xyaw ua ke: kev tsim kho ntawm polycarboxylate superplasticizer yog nyob ntawm kev tsim qauv, cov homas, thiab hom kev xav tau. Nws yog ib qho tseem ceeb kom ua raws cov lus pom zoo.
• Kev Kuaj Xyuas Kev Ntsuas: Ua kev sib raug zoo kom paub meej tias tus superplasticizer yog sib xws nrog lwm cov grout sib xyaw, suav nrog cov cement, ntxiv, thiab accixtures.
• Qhov zoo ntawm cov cement: qhov zoo ntawm cov xis mas siv nyob rau hauv cov ntaub pua chaw ua ke tuaj yeem cuam tshuam rau kev ua tau zoo ntawm superplasticer. Siv cov cement zoo yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig kev ua tau zoo.
• Daim ntawv thov cov xwm txheej: Xav txog qhov kub thiab txias, av noo, thiab lwm cov neeg ib puag ncig thaum lub sij hawm ntawm cov zaub mov tsis zoo los ua kom ntseeg tau tias yog kev ua tau zoo.

Hauv cov ntsiab lus, polycarboxylate superplasticizers ua haujlwm tseem ceeb hauv kev txhim kho cov kev ua haujlwm ntawm kev ua haujlwm tsis zoo, thiab txhawb kev ua kom zoo dua qub thiab kev txhim kho lub zog zoo dua qub. Lawv siv ua ke rau cov kev ua tau zoo thiab kev ruaj khov ntawm kev ua haujlwm.
