Cov teeb meem zoo sib xws thiab kev txheeb xyuas cov txheej txheem ntawm redispersible latex hmoov

Nrog rau txoj kev loj hlob sai ntawm kev lag luam hauv tsev hluav taws xob txuag hluav taws xob, ntau thiab ntau R & D thiab cov tuam txhab tsim khoom tau nkag mus rau hauv R & D thiab tsim cov khoom siv hluav taws xob rov ua dua tshiab, thiab cov neeg siv khoom muaj ntau thiab ntau chav rau kev xaiv, tab sis tib lub sijhawm, zoo ntawm redispersible polymer hmoov tau ua tsis ncaj. , sib xyaw ntses thiab zaj. Txhawm rau txo cov nqi, qee cov tuam txhab lag luam tsis quav ntsej txog cov qauv zoo, tsis zoo li cov khoom zoo, thiab qee tus txawm siv cov hmoov nplej zoo tib yam li cov hmoov latex redispersible los muag ntawm tus nqi qis raws li kev qhia ntawm redispersible latex hmoov, uas tsis tsuas yog cuam tshuam kev lag luam tab sis kuj. deceives neeg siv khoom. Tab sis nyob rau hauv kev lag luam kev lag luam uas qhov zoo tshaj plaws muaj sia nyob, qhov zoo yog lub hauv paus ntawm kev txhim kho kom ruaj khov, thiab tsis muaj lub ntsej muag cuav tuaj yeem npog nws. Nyob rau hauv ib lo lus: zoo yog lub yardstick ntawm tus nqi, hom yog daim ntawv lo ntawm zoo, thiab kev ua lag luam yog qhov kawg xeem tus qauv.

◆ Ua ntej ntawm tag nrho cov, cia peb tsom xam cov teeb meem zoo ntawm redispersible latex hmoov, nrog rau cov txheej txheem thiab kev puas tsuaj ntawm unscrupulous manufacturers kom txo nqi:

◆ Yuav ua li cas kom paub qhov txawv los yog txheeb xyuas qhov zoo ntawm redispersible latex hmoov? Txhawm rau nrhiav txoj hauv kev, pib nrog kev txheeb xyuas:

1. Kev soj ntsuam ntawm cov ntsuas kev tsim khoom

Qhov taw qhia yog lub hauv paus rau kev ntsuas qhov zoo ntawm redispersible latex hmoov. Tus qauv index yog tus naj npawb embodiment ntawm qhov kev ua tau zoo ntawm cov hmoov polymer redispersible. Yog tias qhov ntsuas qhov ntsuas ntawm cov khoom siv hluav taws xob hloov pauv tau ntau dua lossis ua tsis tau raws li tus qauv, nws yuav muaj kev cuam tshuam ncaj qha rau nws qhov kev ua tau zoo. Cov laj thawj tseem ceeb rau qhov ntsuas qhov txawv txav yog cov teeb meem kev tsim khoom, xws li cov cuab yeej siv rov qab, cov khoom siv tsis tu ncua lossis kev laus, kev siv cov khoom pheej yig thiab cov khoom tsis zoo, thiab cov khoom lag luam lax tshuaj xyuas cov khoom tiav. Dab tsi ntxiv, qee cov tuam txhab tsim khoom siv sijhawm los txo cov nqi, tsis hais qhov zoo, thiab tsis zoo. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv tus kws tshaj lij thiab txhim khu kev qha cov chaw tsim khoom.

2. Kev txheeb xyuas qhov ua tau zoo

1. Redispersibility: latex hmoov nrog zoo redispersibility yuav yaj nyob rau hauv dej los tsim ib tug ruaj khov emulsion, thiab particle loj tis yog zoo ib yam li cov thawj emulsion. Roj hmab hmoov nrog tsis zoo redispersibility, uas tsis tuaj yeem hloov kho zoo ib yam, thiab tej zaum yuav muaj cov polymers uas tsis yog redispersible.

2. Zaj duab xis-forming zog ntawm roj hmab hmoov: Zaj duab xis-forming zog yog lub hauv paus ntawm mortar hloov khoom xws li adhesion. Cov khoom ua yeeb yaj kiab tsis zoo yog feem ntau tshwm sim los ntawm kev sib ntxiv ntawm cov khoom siv tsis zoo lossis cov khoom siv tsis zoo. Cov hmoov zoo redispersible latex hmoov muaj cov yeeb yaj kiab zoo nyob rau hauv chav tsev kub, thiab cov neeg uas muaj cov yeeb yaj kiab tsis zoo hauv chav sov feem ntau muaj teeb meem zoo ntawm cov ntsiab lus ntawm cov polymer lossis cov hmoov tshauv.

3. Dej tsis kam ntawm zaj duab xis: Redispersible latex hmoov muaj cov yeeb yaj kiab zoo tsim thiab kuj muaj cov dej tsis zoo. Cov hmoov latex nrog cov dej tsis zoo feem ntau muaj ntau cov dej-soluble polymers.

3. Kev soj ntsuam cov txiaj ntsig ntawm daim ntawv thov

Txiav txim siab raws li tus qauv siv tau:

1. Qhuav daim ntawv cog lus muaj zog thiab dej-resistant bond zog: daim ntawv cog lus tsis zoo, thiab muaj teeb meem zoo nyob rau hauv cov nqe lus ntawm polymer los yog tshauv.

2. Flexibility thiab cuam tshuam tsis kam: Qhov kev hloov pauv tsis zoo, muaj cov teeb meem zoo hauv cov khoom siv polymer, thiab kev hloov pauv tau txo qis thaum siv, uas yuav muaj cov yas yas.

3. Hydrophobic thiab non-hydrophobic: Qhov saum npoo yog hydrophobic heev, uas tuaj yeem txo qhov kev ua haujlwm thiab kev sib khi lub zog ntawm cov mortar.

4. Flow thiab rheology: Lub rheology tsis zoo, thiab muaj teeb meem zoo hauv cov khoom siv polymers lossis cov khoom ntxiv.

5. Ua npuas ncauj thiab defoaming: ua npuas ncauj tsis zoo, teeb meem zoo nrog cov khoom siv polymers, tshauv lossis cov khoom ntxiv.

◆ Ntau txoj hauv kev yooj yim los txheeb xyuas cov hmoov latex redispersible:

1. Cov txheej txheem tshwm sim: npog me me ntawm redispersible latex hmoov thinly thiab tusyees ntawm qhov chaw ntawm lub khob huv si nrog lub iav pas nrig, tso lub iav phaj rau ntawm daim ntawv dawb, thiab pom qhov pom ntawm qhov pom ntawm cov khoom, cov khoom txawv teb chaws thiab coagulation.

2. Txoj kev sib cais: Siv ib qho me me ntawm cov hmoov latex redispersible thiab muab tso rau hauv 5 zaug hauv dej, do ua ntej thiab tos 5 feeb kom pom. Nyob rau hauv txoj cai, qhov tsawg insoluble teeb meem uas precipitates rau hauv qab txheej, qhov zoo dua qhov zoo ntawm redispersible latex hmoov.

3. Txoj kev tshauv: Siv ib qho nyiaj ntawm redispersible latex hmoov, hnyav, muab tso rau hauv ib lub thawv hlau, kub rau li 600 degrees, kub kub rau li 30 feeb, txias rau chav tsev kub, thiab hnyav nws. dua. Zoo zoo rau lub teeb yuag.

4. Zaj duab xis-forming txoj kev: Siv ib tug npaum li cas ntawm redispersible latex hmoov, muab tso rau hauv 2 lub sij hawm ntawm dej, do tusyees, cia nws sawv ntsug rau 2 feeb, do dua, ua ntej ncuav cov tshuaj rau ntawm ib tug ca iav, ces lub khob muab tso rau. nws nyob rau hauv ib tug ventilated ntxoov ntxoo. Tom qab ziab, saib xyuas tias qhov zoo nrog lub siab transparency yog qhov zoo.
