UAA Expansion Agent

UAE nthuav dav tus neeg sawv cev yog cov khoom siv dav siv hauv kev tsim kho vaj tse thiab kev tsim kho kev lag luam. Nws ua los ntawm reacting nrog hydrating cement paste, thiab tuaj yeem muab ntxiv rau ntau yam pob zeb thiab mortar compositions los txhim kho lawv cov khoom. Cov hauv qab no yog qee qhov ntawm daim ntawv thov loj thiab kev tsim kho lub hom phiaj ntawm UAA nthuav dav tus neeg sawv cev:

1. Pob zeb thiab mortar mixtures

UEA feem ntau yog siv rau hauv cov pob zeb thiab mortar sib tov los txhim kho lawv cov khoom xws li kev ua haujlwm, ntom ntom, porosity, thiab compressive zog. Nws tau raug pov thawj tias qhov sib ntxiv ntawm qhov tsim nyog ntawm UEA tuaj yeem txhim kho kev ua tau zoo ntawm Portland cement pob zeb, kev ua haujlwm siab pob zeb, pavement pob zeb thiab lwm yam. Tsis tas li ntawd, nws tseem tuaj yeem txo qhov shrinkage ntawm pob zeb thiab txo qhov tawg los ntawm kev hloov kub.

2. Kev kho thiab kho cov vaj tse pob zeb

UEA tuaj yeem siv rau hauv kev kho vaj tse thiab kev kho kom zoo dua qub los txhim kho cov kav ntev thiab lub zog ntawm cov pob zeb puas. Cov khoom siv kho kom zoo yuav muaj cov cuab yeej zoo thiab ua haujlwm siab rau tshuaj lom neeg thiab ib puag ncig degradation. Tsis tas li ntawd, nws tuaj yeem siv los tsim cov khoom siv kho kom zoo, cov neeg ua haujlwm sib txuas thiab cov grouts, uas tuaj yeem ua kom lub sijhawm ntev ntawm cov qauv.

3. Tswj Shrinkage thiab nthuav dav ntawm pob zeb

UEA tuaj yeem tswj tau qhov shrinkage thiab nthuav dav ntawm cov pob zeb los ntawm kev tswj cov dej hauv qhov sib tov. Raws li cov dej evaporates, UEA yuav hnov ​​​​mob nrog cov cement paste thiab tsim cov roj, uas tsim cov voids me me hauv cov pob zeb loj thiab txo kev ntxhov siab. Qhov no yuav pab txo qhov tawg thiab distortion los ntawm shrinkage thiab expansion.

4. andmine Filling thiab Grouting

UEA tuaj yeem siv rau hauv kev ua haujlwm hauv av xws li tunneling, shaft sinking thiab thee mining. Nws tuaj yeem muab ntxiv rau cov sib tov sib xyaw kom tswj tau lub sijhawm teeb tsa thiab tiv thaiv kev sib cais ntawm cov khoom sau. Nws tuaj yeem txhim kho lub zog compressive thiab tiv thaiv dej nkag.

5. Av Stabilization

UEA tuaj yeem siv los txhim kho cov av hauv lub hauv paus engineering thiab kev tsim kho. Nws tuaj yeem ntxiv rau cov av-cement sib tov kom txo cov plasticity Performance index ntawm cov av thiab ua kom lawv lub zog. Qhov no yuav pab kom txo tau cov av yaig thiab txhim kho kev ruaj ntseg ntawm txoj kab nqes.

Hauv kev xaus, UEA yog cov khoom siv ntau yam uas tuaj yeem txhim kho cov khoom ntawm pob zeb thiab mortar hauv ntau daim ntawv thov kev tsim kho. Nws daim ntawv thov ntau suav nrog kev sib xyaw ua ke tsim, kho thiab kho dua tshiab, tswj kev shrinkage thiab nthuav dav, mine filling thiab grouting, thiab av stabilization. Nws cov kev ua tau zoo heev tuaj yeem txhim kho cov kav ntev thiab lub zog ntawm cov qauv.
