Redispersible polymer hmoov cov khoom yog cov dej-soluble redispersible hmoov, uas tau muab faib ua ethylene / vinyl acetate copolymer, vinyl acetate / tertiary ethylene carbonate copolymers, acrylic copolymer, thiab lwm yam, nrog polyvinyl cawv raws li kev tiv thaiv colloid. Cov hmoov no tuaj yeem hloov pauv sai sai rau hauv emulsion tom qab sib cuag nrog dej. Vim muaj peev xwm khi tau siab thiab cov khoom tshwj xeeb ntawm cov khoom siv rov ua dua tshiab polymer, xws li: dej tsis kam, kev tsim kho thiab rwb thaiv tsev kub, thiab lwm yam., lawv cov kev siv ntau yam yog dav heev.
Cov yam ntxwv ua haujlwm
Nws muaj qhov zoo tshaj plaws kev sib txuas lub zog, txhim kho qhov yooj yim ntawm cov tshuaj khib nyiab thiab muaj lub sijhawm qhib ntev dua, muab cov tshuaj khib nyiab nrog cov alkali tiv thaiv zoo, thiab txhim kho cov nplaum, flexural zog, dej tsis kam, plasticity thiab hnav tsis kam ntawm mortar. Ntxiv nrog rau cov cuab yeej tsim kho, nws muaj zog ua kom yooj yim dua nyob rau hauv qhov hloov tau yooj yim los tiv thaiv mortar.
Daim ntawv thov teb
1. Sab nrauv phab ntsa thermal rwb thaiv tsev: Bonding mortar: xyuas kom meej tias cov mortar ruaj khov rau phab ntsa thiab EPS board. Txhim kho daim ntawv cog lus zog. Plastering mortar: los xyuas kom meej lub zog txhua yam, tawg tsis kam thiab durability ntawm thermal rwb thaiv tsev system, thiab cuam tshuam tsis kam.
2. Pobzeb nplaum thiab tus neeg sawv cev ntawm cov pobzeb: Pobzeb nplaum: Muab cov khoom siv muaj zog rau cov tshuaj khib nyiab, thiab muab cov mortar txaus rau strain qhov sib txawv thermal expansion coefficients ntawm substrate thiab ceramic pobzeb. Filler: Ua kom cov mortar impermeable thiab tiv thaiv kev nkag ntawm dej. Nyob rau tib lub sijhawm, nws muaj qhov zoo adhesion nrog ntug ntawm cov pobzeb, tsis tshua muaj shrinkage thiab yooj.
3. Kev kho cov pobzeb thiab ntoo plastering putty: Txhim kho qhov adhesion thiab bonding zog ntawm putty rau tshwj xeeb substrates (xws li pobzeb nto, mosaics, plywood thiab lwm yam du nto), thiab xyuas kom meej tias lub putty muaj zoo yooj yooj yim rau strain lub expansion coefficient ntawm lub substrate. .
Plaub, sab hauv thiab sab nrauv phab ntsa putty: txhim kho lub zog sib txuas ntawm lub putty kom ntseeg tau tias cov putty muaj qee qhov kev hloov pauv kom tsis txhob cuam tshuam cov txiaj ntsig ntawm qhov sib txawv ntawm kev nthuav dav thiab kev ntxhov siab uas tsim los ntawm cov txheej txheem sib txawv. Xyuas kom meej tias lub putty muaj zoo aging kuj, impermeability thiab noo noo kuj.
5. Self-leveling pem teb mortar: xyuas kom meej qhov sib txuam ntawm elastic modulus ntawm lub mortar thiab kev tiv thaiv rau dabtsi yog khoov quab yuam thiab tawg. Txhim kho qhov hnav tsis kam, daim ntawv cog lus lub zog thiab cohesion ntawm mortar.
6. Interface mortar: txhim kho lub zog saum npoo ntawm lub substrate thiab xyuas kom muaj kev sib koom ua ke ntawm cov mortar.
7. Cement-based waterproof mortar: xyuas kom tsis muaj dej tsis zoo ntawm cov mortar txheej, thiab tib lub sij hawm muaj adhesion zoo nrog lub hauv paus nto los txhim kho cov compressive thiab flexural zog ntawm cov tshuaj khib.
8. Kho mortar: xyuas kom meej tias qhov nthuav dav coefficient ntawm mortar thiab cov khoom siv hauv paus sib tw, thiab txo cov elastic modulus ntawm mortar. Xyuas kom lub mortar muaj dej txaus, breathability thiab adhesion.
9. Masonry plastering mortar: txhim kho dej tuav. Txo cov dej poob mus rau qhov ntxeem tau substrate. Txhim kho qhov yooj yim ntawm kev tsim kho kev lag luam thiab txhim kho kev ua haujlwm zoo.
Qhov zoo
Nws tsis tas yuav khaws cia thiab thauj nrog dej, txo cov nqi tsheb thauj mus los; lub sij hawm cia ntev, antifreeze, yooj yim khaws cia; ntim me me, lub teeb yuag, yooj yim siv; tuaj yeem sib xyaw nrog hydraulic binders los ua hluavtaws cob hloov Lub premix tsuas yog siv los ntawm kev ntxiv dej, uas tsis tsuas yog zam kev ua yuam kev hauv kev sib xyaw ntawm qhov chaw tsim kho, tab sis kuj txhim kho kev nyab xeeb ntawm cov khoom tuav.
