Redispersible looj hmoov (RDP) ua lub luag haujlwm tseem ceeb hauv cov khoom lag luam tshwj xeeb. Nws yog ib qho khoom siv los ntawm ziab thiab hmoov yas cov lus. Nws tuaj yeem raug muab rov qab rau hauv dej los ua ib qho emulsion nrog cov khoom nplaum. Nws yog dav siv nyob rau hauv ntau lub tsev thiab cov ntaub ntawv tsim kho, tshwj xeeb tshaj yog nyob rau hauv thaj teb qhuav-mixeded.
1. Txhim kho lub zog bonding
Cov polymer hais hauv cov redispersible looj hmoov tuaj yeem muab rov qab los tom qab cov khoom sib khi zoo nrog Caas hais tawm, Quahtz xuab zeb thiab lwm yam. Cov kev txhim kho no hauv kev sib khib tsuas yog tso cai rau lub zog ua kom zoo dua qub, thiab tuaj yeem txhim kho lub zog zoo dua qub, thiab tuaj yeem txhim kho lub zog ua kom zoo dua qub, thiab tuaj yeem txhim kho lub zog zoo, thiab muaj peev xwm txhim kho lub zog zoo, tab sis kuj tuaj yeem txhim kho lub zog zoo, tab sis kuj tuaj yeem txhim kho lub zog zoo, tab sis kuj tuaj yeem txhim kho lub zog zoo, tab sis kuj tuaj yeem txhim kho lub zog zoo, tab sis kuj muaj peev xwm txhim kho lub zog zoo, tab sis kuj tuaj yeem txhim kho cov tshuaj khib nyiab zoo siab, thiab muaj peev xwm txhim kho cov tshuaj khib siab, tab sis kuj tuaj yeem txhim kho lub zog zoo, tab sis kuj tuaj yeem txhim kho lub zog zoo, tab sis kuj muaj peev xwm txhim kho lub zog zoo, tab sis kuj tuaj yeem txhim kho lub zog zoo, tab sis kuj muaj peev xwm txhim kho lub zog zoo, tab sis kuj tuaj yeem txhim kho cov tshuaj khib nyiab zoo siab, thiab muaj peev xwm ua kom zoo dua qub, tab sis kuj tuaj yeem txhim kho lub zog zoo, tab sis kuj tuaj yeem txhim kho lub zog zoo, thiab muaj peev xwm ua kom zoo dua qub, thiab tuaj yeem txhim kho lub zog zoo, thiab muaj peev xwm txhim kho lub zog ua kom zoo dua qub
2. Txhim kho cov haujlwm ntawm cug
Cov hmoov sib xyaw qhuav nrog qhov sib ntxiv ntawm cov recispersible looj hmoov feem ntau qhia kev ua haujlwm zoo dua. Nws tuaj yeem txhim kho qhov kev ua haujlwm ntawm lub tshuaj khib, suav nrog nthuav tawm lub sijhawm ua haujlwm, txhim kho cov dej khaws cia thiab nce ntxiv. Qhov no txhais tau tias cov neeg ua haujlwm tsim kho muaj sijhawm ntau dua los sib xyaw thiab kev zam cov teeb meem kev ziab kom qhuav lossis dej tsis huv. Qhov kev txhim kho no yog qhov tshwj xeeb tshaj yog rau cov haujlwm loj lossis cov scenes ua kev ua haujlwm.
3. Txhim kho kev tawg
RDP tuaj yeem nce cov tawg tawm ntawm cug, tshwj xeeb tshaj yog nyob rau hauv cov kev mob ntawm kev ziab shrinkage thiab ntsuas kub. Cov qauv polymer ntawm cov hmoov yas tau zoo tuaj yeem tiv thaiv kev tsim ntawm microcacks tshwm sim los ntawm cov rog sab nraud. Thaum lub npoo hluav taws xob muaj kev cuam tshuam los ntawm cov chaw sab nraud, cov hmoov yas qab ntawm kev sib cav sib ceg thiab kev ntxhov siab, yog li txo cov cracks. Rau cov phiaj xwm xws li kev kho kom zoo nkauj phab ntsa thiab qhuav dai pob zeb, kev txhim kho cov kab nrib pleb muaj kev pab ntau kawg ntawm lub neej ntawm cov khoom siv.
4. Txhim kho dej tsis kam thiab kav ntev
Redispersible looj cov hmoov tuaj yeem txhim kho cov dej tsis kam ntawm cov tshuaj khib qhuav. Los ntawm kev ntxiv cov hmoov nplej rau lub tshuaj khib, cov qauv pore ntawm lub cug yuav hloov, txo cov kev nkag mus rau dej. Qhov kev txhim kho no ua rau lub tshuaj khib ntau cov dej-tiv taus thiab haum rau kev siv cov phiaj xwm noo, thaj chaw sab nrauv xws li chav dej thiab chav ua noj. Ntxiv rau, cov hmoov yas looj tau kuj tseem tuaj yeem txhim kho cov kev sib cav uas nws tau ua haujlwm thaum lub sijhawm siv sijhawm ntev thiab kev kho kom tsawg.
5. Txhim kho impermability thiab tshuaj lom corrosion tsis kam
Qhov sib ntxiv ntawm cov hmoov zoo tsis tsuas yog ua rau cov dej tsis kam ntawm tshuaj cug, tab sis kuj txhim kho nws cov impermability. Hauv qee qhov chaw tshwj xeeb, xws li cug rau hauv av tej nqis zog lossis cov tub sab ib puag ncig, impermabeability yog qhov tseem ceeb tshaj plaws taw qhia. Cov hmoov nplej puas tuaj yeem ua cov qauv denser, txo cov kev nkag mus rau dej thiab lwm yam tshuaj, thiab yog li nthuav tawm cov kev pabcuam lub neej ntawm cov khoom siv. Ntxiv rau, cov hmoov yas kuj tseem tuaj yeem txhim kho cov tshuaj corrosion tawm tsam ntawm cug, uas yog qhov tseem ceeb rau qee cov nroj tsuag tshwj xeeb, dej haus cov nroj tsuag, thiab lwm yam.
6. Txhim kho cov hluav taws xob ruaj khov
Redispersible looj cov hmoov kuj tseem tuaj yeem tswj hwm qee yam kev ruaj khov ntawm qhov kub, yog li ntawd lub tshuaj kho kom zoo dua nyob rau hauv cov kev kub siab ib puag ncig. Qhov no yog qhov tseem ceeb rau qee cov haujlwm tsim tshwj xeeb, xws li sab nrauv daim tawv nqaij daim tawv thiab hluav taws xob tso pa rau cov nroj tsuag muaj. Cov hmoov yas looj app tuaj yeem tswj tau lub cug cug hauv cov chaw ntsuas hluav taws xob thiab kev tshuaj khib tawg lossis kev hloov qhov sib txawv.
7. Txhim kho lub zog compressive thiab elasticity ntawm cug
Tom qab ntxiv recispersible looj cov hmoov kom qhuav-sib nphu cug, nws tuaj yeem txhim kho lub zog compressive thiab elasticity ntawm cug. Tshwj xeeb tshaj yog thaum nws yuav tsum tau tiv thaiv cov nra loj lossis tshee, elasticity cug yog qhov tseem ceeb tshwj xeeb. Los ntawm kev txhim kho elasticity ntawm cug, looj cov hmoov tau zoo dua rau cov txheej txheem me me ntawm cov txheej txheem sib tov thiab tsis txhob muaj kuab tawg los ntawm kev txav mus los ntawm substrate txav.
8. Muaj feem xyuam rau ntau qhov chaw tsim khoom
Muaj ntau hom kev sib xyaw tshwj xeeb uas muaj cov ntawv thov hluav taws xob ntau, thiab lwm yam kev ua tau zoo raws li cov kev xav tau sib txawv thiab hloov kho rau ntau qhov chaw tsim khoom. Los kho cov hom thiab ntau npaum li cas ntawm cov hmoov yas, cov kev ua tau zoo ntawm cov kev xav tau, tawg tsis kam, thiab lwm yam.
9. Kev txuag nqi
Txawm hais tias lub redispersible looj hmoov nws tus kheej yuav ua rau cov nqi kho mob thiab tshuaj khib nyiab thiab ntev ua tiav cov txiaj ntsig ntawm kev txuag nqi. Tshwj xeeb tshaj yog rau coll siv tau siv nyob rau qee qhov chaw tshwj xeeb, kev siv cov hmoov zoo dua tuaj yeem txo cov nqi kho tau los ntawm kev hloov ib puag ncig.
RDP plays Lub Luag Haujlwm Tseem Ceeb hauv kev sib xyaw qhuav-cug cug. Nws tsis tuaj yeem txhim kho cov nplaum, tawg, cov dej tshuaj khib, tab sis tseem txhim kho nws cov impetability, tshuaj lom neeg tsis kam, kev ruaj khov. Los ntawm kev siv cov hmoov liab redinpersible looj tshuaj tsw qab, ua kom zoo dua qub txhim kho, ua kom muaj cov khoom siv tshiab rau cov khoom siv, thiab muaj cov ntawv thov kom muaj txiaj ntsig zoo.
