Dispersible polymer hmoov (RDP) yog ib qho kev ua tau zoo ntawm cov tshuaj polymer siv hauv kev tsim kho thiab kev lag luam. Nws yog cov khoom siv hmoov uas tau los ntawm cov tshuaj tsuag kom qhuav cov emulsion polymer, thiab muaj cov cuab yeej ntawm redispersing hauv dej los tsim ib qho emulsion ruaj khov. RDP yog dav siv nyob rau hauv ntau yam ntaub ntawv hauv tsev, tshwj xeeb tshaj yog nyob rau hauv qhuav mortar, pobzeb nplaum, sab nrauv phab ntsa rwb thaiv tsev system (ETICS), thiab waterproof coatings.
1. Qhuav mortar
Ib qho ntawm feem ntau siv ntawm RDP yog nyob rau hauv qhuav mortar. Nws tuaj yeem txhim kho qhov adhesion, yooj thiab tawg tsis kam ntawm mortar, ua kom yooj yim rau kev tsim thiab txhim kho kev tsim kho kom zoo. Tshwj xeeb, lub luag haujlwm ntawm RDP hauv mortar qhuav suav nrog:
Txhim kho daim ntawv cog lus muaj zog: RDP tuaj yeem tsim cov yeeb yaj kiab elastic tom qab cov tshuaj khib tau kho. Cov yeeb yaj kiab no muaj lub zog siab, uas tuaj yeem txhim kho qhov adhesion ntawm mortar thiab substrate thiab txo qhov kev pheej hmoo ntawm kev tawg thiab poob.
Txhim kho qhov yooj yim: Txij li cov yeeb yaj kiab tsim los ntawm RDP yog hloov tau, nws tuaj yeem tswj tau qhov kev ncaj ncees ntawm mortar thiab tiv thaiv kev tawg thaum lub tsev qauv txav los yog deforms me ntsis.
Txhim kho kev tsim kho: RDP tuaj yeem txhim kho cov dej ntws thiab lubricity ntawm cov mortar, ua kom kev tsim kho yooj yim dua, tshwj xeeb tshaj yog txo kev siv zog thiab kev txhim kho kev tsim kho thaum tsim kho thaj tsam loj.
2. Cov nplaum nplaum
Hauv cov pobzeb nplaum, qhov sib ntxiv ntawm RDP tuaj yeem txhim kho kev ua haujlwm ntawm cov pobzeb nplaum, nrog rau kev sib txuas ntawm lub zog, cov khoom tiv thaiv plam thiab yooj yim ntawm kev tsim kho.
Txhim kho adhesion: RDP tuaj yeem tsim cov txheej txheem kev sib raug zoo tom qab cov pobzeb nplaum dries, kom ntseeg tau tias cov vuas tuaj yeem txuas mus rau phab ntsa lossis hauv pem teb.
Txhim kho cov khoom tiv thaiv plam: RDP tuaj yeem tiv thaiv cov vuas los ntawm kev ntog thaum lub sij hawm tsim kho thiab xyuas kom meej tias cov vuas tuaj yeem nyob hauv qhov kev txiav txim siab ua ntej thaum paving.
Txhim kho kev yooj yim ntawm kev tsim kho: Tom qab ntxiv RDP rau pobzeb nplaum, nws qhov sib xws yog yooj yim rau kev tswj, cov nplaum txheej yog sib xws thaum paving, thiab qhov nyuaj ntawm kev tsim kho yog txo.
3. Sab nrauv phab ntsa rwb thaiv tsev (ETICS)
Daim ntawv thov ntawm RDP nyob rau hauv sab nrauv phab ntsa rwb thaiv tsev yog feem ntau xav txog nyob rau hauv kev txhim kho lub sib raug zoo lub zog thiab durability ntawm rwb thaiv tsev txheej. Cov txheej rwb thaiv tsev feem ntau siv cov khoom siv hnyav xws li nthuav dav polystyrene (EPS) lossis extruded polystyrene (XPS), uas yuav tsum tau ua kom ruaj khov rau sab nrauv phab ntsa ntawm lub tsev, thiab qhov sib ntxiv ntawm RDP tuaj yeem txhim kho kev sib raug zoo ntawm cov ntaub ntawv no.
Txhim kho kev sib raug zoo zog: RDP ua rau lub rwb thaiv tsev board ntau ruaj khov rau ntawm phab ntsa sab nrauv, tiv thaiv cov txheej rwb thaiv tsev los ntawm kev poob vim qhov kub thiab txias los yog sab nraud quab yuam.
Txhim kho durability: RDP kuj tuaj yeem txhim kho qhov kev tiv thaiv kev laus ntawm cov txheej txheem rwb thaiv tsev thiab txuas ntxiv lub neej kev pab cuam ntawm lub tsev, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav.
4. Waterproof txheej
Daim ntawv thov ntawm RDP nyob rau hauv waterproof txheej yog tsuas yog los txhim kho cov waterproofness, yooj thiab tawg tsis kam ntawm txheej. Cov yeeb yaj kiab polymer tsim los ntawm RDP hauv txheej txheej tuaj yeem tiv thaiv kev nkag mus ntawm dej, yog li txhim kho cov dej tsis zoo.
Txhim kho cov dej tsis zoo: Cov qauv duab ntom ntom tsim los ntawm RDP tuaj yeem thaiv cov dej nkag mus tau zoo, tshwj xeeb tshaj yog rau thaj chaw uas muaj dej tsis zoo xws li lub ru tsev, hauv qab daus thiab chav dej.
Ua kom yooj yim dua: RDP hauv cov txheej txheem dej tsis muaj dej tuaj yeem muab cov txheej txheem yooj yim, hloov mus rau me ntsis deformation ntawm substrate, thiab tiv thaiv cov txheej los ntawm kev tawg.
Txhim kho kev tsim kho ntawm cov txheej txheem: Kev sib ntxiv ntawm RDP ua rau kev tsim kho cov txheej txheem dej tsis zoo, cov txheej txheej tsis sib xws thiab tsis tshua muaj npuas thiab tawg.
5. Lwm yam kev siv
Ntxiv nrog rau cov ntawv thov tseem ceeb saum toj no, RDP kuj tuaj yeem siv rau hauv cov plag tsev tus kheej, cov ntaub ntawv kho phab ntsa, cov khoom siv gypsum thiab cov khoom siv hluav taws xob thermal. Hauv cov ntawv thov no, RDP kuj tseem ua lub luag haujlwm hauv kev txhim kho cov adhesion ntawm cov ntaub ntawv, txhim kho kev tsim kho kom yooj yim, thiab ua kom tawg tsis kam thiab kav ntev.
Raws li cov tshuaj siv tau zoo heev, dispersed latex hmoov (RDP) yog siv dav hauv ntau qhov chaw vim nws cov khoom siv tshuaj lom neeg tshwj xeeb. Nws tsis tsuas yog txhim kho kev ua haujlwm ntawm cov khoom siv hauv tsev, tab sis kuj txhim kho qhov yooj yim ntawm kev tsim kho thiab kev ua haujlwm ntev ntawm lub tsev kawg. Nrog rau kev txhim kho txuas ntxiv ntawm kev tsim kho thev naus laus zis, daim ntawv thov kev lag luam ntawm RDP yuav txuas ntxiv mus ntxiv, thiab nws xav tias yuav ua lub luag haujlwm tseem ceeb hauv kev siv dav hauv kev lag luam thiab kev tsim kho yav tom ntej.
