Redispersible latex hmoov
Sab hauv thiab sab nrauv phab ntsa putty hmoov, pobzeb nplaum, pobzeb taw tes tus neeg saib xyuas, cov hmoov qhuav interface tus neeg sawv cev, sab nraud thermal rwb thaiv tsev mortar rau sab nrauv phab ntsa, tus kheej-leveling mortar, kho mortar, hniav mortar, waterproof mortar sab nraud thermal rwb thaiv tsev qhuav-siv mortar.Nyob rau hauv lub mortar, nws yog los txhim kho lub brittleness, siab elastic modulus thiab lwm yam tsis muaj zog ntawm cov tsoos cement mortar, thiab muab cov cement mortar nrog kev yooj yim dua thiab tensile daim ntawv cog lus lub zog, thiaj li tiv thaiv thiab ncua sij hawm tsim ntawm cement mortar tawg.Txij li thaum lub polymer thiab cov mortar tsim ib qho kev sib txuas network qauv, ib tug nruam polymer zaj duab xis yog tsim nyob rau hauv lub pores, uas ntxiv dag zog rau cov kev sib raug zoo ntawm cov aggregates thiab blocks ib co pores nyob rau hauv lub mortar, yog li cov hloov mortar tom qab hardening yog zoo dua li cov cement mortar.Muaj kev txhim kho loj.
Ib qho: Lub luag haujlwm ntawm redispersible latex hmoov hauv putty yog cov hauv qab no
1. Txhim kho qhov adhesion thiab mechanical zog ntawm putty.Redispersible latex hmoov yog cov hmoov nplaum ua los ntawm ib qho tshwj xeeb emulsion (siab molecular polymer) tom qab tshuaj tsuag kom qhuav.Cov hmoov no tuaj yeem hloov pauv sai sai rau hauv emulsion tom qab sib cuag nrog dej, thiab muaj cov khoom zoo ib yam li thawj emulsion, uas yog, zaj duab xis tuaj yeem tsim tom qab dej evaporates.Cov yeeb yaj kiab no muaj qhov hloov tau yooj yim, huab cua tsis kam thiab ua haujlwm rau ntau yam High adhesion rau substrates.Tsis tas li ntawd, hydrophobic latex hmoov tuaj yeem ua rau cov tshuaj khib nyiab tsis zoo.
2. Txhim kho lub cohesion ntawm putty, zoo heev kuj, alkali tsis kam, hnav tsis kam, thiab txhim khu lub flexural zog.
3. Txhim kho cov dej tsis zoo thiab permeability ntawm putty.
4. Txhim kho cov dej tuav ntawm putty, nce lub sijhawm qhib, thiab txhim kho kev ua haujlwm
5. Txhim kho qhov cuam tshuam tsis kam ntawm putty thiab txhim khu lub durability ntawm putty.
Ob: Lub luag hauj lwm ntawm redispersible latex hmoov nyob rau hauv mortar yog cov nram qab no yam
1. Txhim kho lub zog compressive thiab flexural zog ntawm mortar.
2. Qhov sib ntxiv ntawm cov hmoov latex nce qhov elongation tus nqi ntawm cov tshuaj khib, yog li txhim kho qhov cuam tshuam toughness ntawm mortar, thiab kuj endows lub mortar nrog ib tug zoo kev nyuaj siab dispersion nyhuv.
3. Txhim kho qhov kev sib txuas ntawm mortar.Lub tshuab sib txuas yog ua raws li qhov adsorption thiab diffusion ntawm macromolecules ntawm cov nplaum nplaum.Nyob rau tib lub sijhawm, cov hmoov roj hmab muaj qee yam permeability thiab tag nrho infiltrates saum npoo ntawm cov khoom siv hauv paus nrog cellulose ether, kom cov khoom nto ntawm lub hauv paus thiab cov plaster tshiab nyob ze, yog li txhim kho Adsorption zoo heev ua rau nws cov kev ua tau zoo.
4. Txo cov elastic modulus ntawm mortar, txhim kho deformation muaj peev xwm thiab txo qhov tshwm sim tawg.
5. Txhim kho qhov hnav tsis kam ntawm mortar.Kev txhim kho ntawm kev hnav tsis kam yog feem ntau yog vim muaj qee yam ntawm cov kua nplaum rau ntawm qhov chaw ntawm lub mortar.Cov kua nplaum hmoov ua raws li daim ntawv cog lus, thiab cov qauv omentum tsim los ntawm cov kua nplaum hmoov tuaj yeem dhau los ntawm qhov thiab cov kab nrib pleb hauv cov cement mortar.Txhim kho kev sib raug zoo ntawm cov khoom siv hauv paus thiab cov khoom siv cement hydration, yog li ua kom hnav tsis kam.
6. Muab cov mortar zoo heev alkali tsis kam.
Peb: Lub luag hauj lwm ntawm redispersible latex hmoov nyob rau hauv pobzeb adhesives yog cov nram qab no yam
1. Raws li tus nqi ntawm cov cement nce, lub zog qub ntawm cov pobzeb nplaum ntxiv, thiab tib lub sijhawm, lub zog tensile nplaum tom qab muab tso rau hauv dej thiab lub zog tensile nplaum tom qab thermal aging kuj nce.Tus nqi ntawm cov cement yuav tsum siab dua 35%.
2. Nrog rau qhov nce ntawm cov nyiaj redispersible latex hmoov, lub tensile daim ntawv cog lus lub zog ntawm cov pobzeb nplaum tom qab immersion nyob rau hauv dej thiab lub tensile daim ntawv cog lus lub zog tom qab tshav kub aging nce raws li, tab sis qhov nce ntawm tensile daim ntawv cog lus zog tom qab tshav kub laus yog kuj tsawg.pom tseeb.
3. Nrog rau qhov nce ntawm cov cellulose ether, tensile nplaum lub zog ntawm cov nplais nplaum tom qab thermal aging nce, thiab tensile nplaum lub zog tom qab soaking hauv dej ua ntej nce thiab tom qab ntawd txo.Cov nyhuv yog qhov zoo tshaj plaws thaum cov ntsiab lus cellulose ether nyob ib ncig ntawm 0.3%.
Yog li ntawd, thaum siv redispersible latex hmoov, peb yuav tsum tau them sai sai rau cov nqi siv, yog li ntawd peb muaj peev xwm tiag tiag ua si nws lub luag hauj lwm.
