Redispersible latex hmoov yog lub ntsiab organic binder nyob rau hauv mortar ntawm sab nraud phab ntsa thermal rwb thaiv tsev system, uas ua kom lub zog thiab kev ua tau zoo ntawm cov txheej txheem tom qab, thiab ua rau tag nrho thermal rwb thaiv tsev system sib xyaw ua ke. Nws kuj yog siv dav hauv lwm cov khoom siv hauv tsev xws li qib high-grade putty hmoov rau sab nrauv phab ntsa. Kev txhim kho kev tsim kho thiab txhim kho kev hloov pauv kuj tseem ceeb heev rau qhov zoo ntawm cov hmoov putty. Txawm li cas los xij, raws li kev lag luam dhau los ua kev sib tw, muaj ntau cov khoom sib xyaw ntawm cov khoom siv rov ua dua tshiab latex hmoov, uas muaj peev xwm ua rau muaj kev pheej hmoo rau cov neeg siv khoom hauv qab mortar putty hmoov. Raws li peb cov kev nkag siab ntawm cov khoom thiab kev soj ntsuam, cov hauv qab no yuav siv tau los pib qhov zoo thiab phem, FYI:
1. Txoj kev sib cais
Raws li qhov sib piv ntawm latex hmoov: dej = 1: 4, dissolve lub redispersible latex hmoov nyob rau hauv dej. Tom qab stirring zoo, cia nws sawv ntsug rau 10 feeb. Yog tias cov av hauv qab qis dua, qhov zoo ntawm qhov kev soj ntsuam ua ntej ntawm cov tshuaj redispersible latex hmoov zoo dua, thiab txoj kev no yog qhov yooj yim rau kev khiav lag luam.
2. Tshauv txoj kev
Siv ib qho nyiaj ntawm cov kua roj hmab rov qab, ntsuas nws, muab tso rau hauv lub thawv hlau, kub txog li 800 degrees, tom qab kub hnyiab ntawm 800 degrees, txias rau chav tsev kub, thiab hnyav dua. Qhov ntau dua qhov hnyav, qhov zoo dua; Txoj kev no yuav tsum tau siv cov cuab yeej sim xws li crucibles, uas tsim nyog rau kev ua haujlwm hauv chav kuaj.
3. Zaj duab xis txheej txheem
Raws li qhov sib piv ntawm cov hmoov latex: dej = 1: 2, dissolve lub redispersible latex hmoov hauv dej. Tom qab nplawm tusyees, cia nws sawv ntsug rau 5 feeb, do dua, ncuav cov tshuaj rau ntawm ib daim ntawm lub khob huv si, thiab muab lub khob tso rau hauv qhov chaw cua thiab qhov chaw ntxoov ntxoo. Tom qab cov dej noo tau evaporated thiab qhuav, tev nws tawm ntawm lub khob. Ua tib zoo saib cov yeeb yaj kiab polymer uas tau muab tshem tawm, qhov siab dua qhov pom, qhov zoo dua qhov zoo. Koj tuaj yeem txiav cov zaj duab xis rau hauv ib daim hlab, tsau rau hauv dej, thiab saib nws tom qab 1 hnub. Qhov tsawg yaj hauv dej, qhov zoo dua qhov zoo; txoj kev no kuj yooj yim rau kev khiav lag luam.
