Yuav ua li cas paub qhov zoo thiab qhov tsis zoo ntawm redispersible latex hmoov?

Redispersible latex hmoov yog lub ntsiab organic binder nyob rau hauv lub mortar ntawm sab nrauv phab ntsa rwb thaiv tsev system, uas ua kom lub zog thiab kev ua tau zoo ntawm lub system nyob rau hauv lub tom ntej theem, thiab ua rau tag nrho cov rwb thaiv tsev system sib xyaw ua ke.Nws kuj tau siv dav hauv lwm cov khoom siv hauv tsev xws li cov phab ntsa thaiv phab ntsa sab nrauv thiab qib high-grade putty hmoov rau cov phab ntsa sab nraud.Kev txhim kho kev tsim kho thiab txhim kho kev hloov pauv kuj tseem ceeb heev rau qhov zoo ntawm cov tshuaj khib thiab cov hmoov putty.

Txawm li cas los xij, raws li kev ua lag luam dhau los ua kev sib tw ntau dua, muaj ntau cov khoom sib xyaw, uas muaj peev xwm ua rau muaj kev pheej hmoo rau cov neeg siv khoom qis qis thiab cov hmoov putty.Raws li peb cov kev nkag siab ntawm cov khoom thiab kev soj ntsuam, peb tuaj yeem siv cov txheej txheem hauv qab no kom paub qhov txawv ntawm qhov zoo thiab qhov tsis zoo.Ua tsaug Thov xa mus rau.

1. Saib xyuas qhov tshwm sim

Xim txawv txav;impurities;tshwj xeeb yog coarse hais;tsis hnov ​​tsw.Qhov zoo li qub yuav tsum yog dawb rau lub teeb daj dawb-ntws cov hmoov tsis muaj ntxhiab tsw tsw.

2. Tshawb xyuas cov hmoov tshauv

Yog tias cov hmoov tshauv muaj siab, nws yuav muaj cov khoom tsis tsim nyog thiab cov ntsiab lus tsis zoo.

3. Tshawb xyuas cov dej noo

Muaj ob qhov xwm txheej ntawm qhov txawv txav ntawm cov dej noo ntau.Yog tias cov khoom tshiab yog siab, nws yuav yog vim tsis zoo siv tshuab thiab cov khoom siv raw;yog tias cov khoom khaws cia siab, nws yuav muaj cov khoom nqus dej.

4. Txheeb xyuas tus nqi pH

Yog tias tus nqi pH txawv txav, tej zaum yuav muaj cov txheej txheem lossis cov khoom siv txawv txav tshwj tsis yog muaj cov lus qhia tshwj xeeb.

5. Iodine kua xim kuaj

Thaum cov tshuaj iodine ntsib cov hmoov txhuv nplej siab, nws yuav tig mus rau hauv indigo xiav, thiab cov tshuaj iodine tov xim yog siv los xyuas seb cov roj hmab hmoov puas yog cov hmoov txhuv nplej siab.

txoj kev ua haujlwm

1) Siv me me ntawm redispersible latex hmoov thiab sib tov rau hauv cov dej ntawm lub raj mis yas, soj ntsuam cov dispersion ceev, seb puas muaj cov khoom tshem tawm thiab nag lossis daus.Nyob rau hauv cov ntaub ntawv ntawm cov dej tsawg thiab cov hmoov roj hmab ntau, nws yuav tsum tau dispersed sai sai thiab yuav tsum tsis txhob muab tshem tawm hais thiab sediment.

2) Ntxiv cov dej me me rau hauv cov hmoov latex redispersible thiab kis nws nrog koj cov ntiv tes.Nws yuav tsum xav tias zoo thiab grainy.

3) Tshaj tawm cov hmoov latex redispersible nrog me me ntawm dej, cia nws qhuav ib txwm ua ib zaj duab xis, thiab tom qab ntawd saib cov yeeb yaj kiab.Nws yuav tsum tsis muaj impurities, tawv thiab elastic.Cov zaj duab xis tsim los ntawm txoj kev no tsis tuaj yeem kuaj xyuas cov dej tsis zoo vim tias cov tshuaj tiv thaiv colloid tsis tau sib cais;Tom qab cov cement thiab quartz xuab zeb sib tov rau hauv zaj duab xis, cov tshuaj tiv thaiv colloid polyvinyl cawv yog saponified los ntawm alkali thiab yog adsorbed thiab sib cais los ntawm quartz xuab zeb.Cov dej yuav tsis tawg dua, thiab kev ntsuas dej tsis kam tuaj yeem ua tiav.

4) Ua cov khoom sim raws li cov qauv thiab ua raws li cov txiaj ntsig.

Lub redispersible latex hmoov nrog hais tej zaum yuav tov nrog hnyav calcium, thiab ib tug tsis muaj hais tsis tau txhais hais tias nws tsis yog tov nrog ib yam dab tsi, thiab ib tug tov nrog lub teeb calcium tsis pom thaum nws dissolves nyob rau hauv dej.
