Feem ntau siv ntawm redispersible latex hmoov
1. Adhesives: pobzeb adhesives, adhesives rau kev tsim kho thiab rwb thaiv tsev boards;
2. Phab ntsa mortar: sab nrauv phab ntsa rwb thaiv tsev mortar, hniav mortar;
3. Pem teb mortar: self-leveling mortar, kho mortar, waterproof mortar, qhuav hmoov interface tus neeg sawv cev;
4. hmoov txheej: sab hauv thiab sab nrauv phab ntsa thiab qab nthab putty hmoov, latex hmoov hloov cov txiv qaub-cement plaster thiab txheej;
5. Joint muab tub lim: ceramic pobzeb taw tes tus neeg saib xyuas, sib koom mortar.
Redispersible latex hmoov tuaj yeem txhim kho lub peev xwm sib txuas thiab tensile lub zog ntawm cov tshuaj khib.Nws muaj qhov zoo tiv thaiv kev poob qis, dej khaws cia thiab ua kom tuab kev ua tau zoo, dej tsis kam, khov-thaw tsis kam, kub laus tiv thaiv, cov khoom xyaw yooj yim, thiab siv tau yooj yim.Xindadi roj hmab hmoov muaj kev sib raug zoo nrog cov cement, tuaj yeem ua tiav hauv cov cement-raws li cov khoom sib xyaw qhuav, tsis txo lub zog ntawm cov cement tom qab kho, tsis tsuas yog tswj cov adhesion zoo, zaj duab xis-tsim zog thiab yooj, tab sis kuj muaj qhov zoo. Huab cua tsis kam, ruaj khov, kev sib txuas ua haujlwm thiab tawg ua haujlwm.Tom qab ziab, nws tuaj yeem tiv thaiv kev yaig ntawm cov pa acidic ntawm phab ntsa, thiab nws tsis yooj yim rau pulverize thiab deliquesce tom qab ntub dej.Nws tuaj yeem txhim kho kev ua haujlwm ntawm mortar, nce lub zog ntawm mortar, txhim kho kev sib txuas ntawm cov mortar thiab ntau yam substrates, txhim kho qhov yooj thiab hloov pauv, compressive zog, flexural zog, hnav tsis kam, toughness, adhesion thiab dej tuav peev xwm, constructability.Tsis tas li ntawd, hydrophobic latex hmoov tuaj yeem ua rau cov tshuaj khib nyiab tsis zoo.
Redispersible latex hmoov tsis tas yuav khaws cia thiab thauj nrog dej, uas txo cov nqi tsheb thauj mus los;nws muaj lub sij hawm cia ntev, yog antifreeze, thiab yooj yim rau khaws cia;lub ntim yog me me, lub teeb hauv qhov hnyav, thiab siv tau yooj yim;nws tuaj yeem tov nrog hydraulic binders los tsim Cov khoom siv hluavtaws-hloov premix tsuas yog yuav tsum tau ntxiv nrog 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.
Redispersible latex hmoov yog siv rau hauv mortar los txhim kho lub brittleness thiab siab elastic modulus ntawm tsoos cement mortar, thiab muab cov cement mortar nrog kev yooj yim dua thiab tensile daim ntawv cog lus lub zog los tiv thaiv thiab ncua cov cement mortar.Qhov tshwm sim ntawm mortar tawg, vim hais tias cov polymer thiab mortar tsim ib tug interpenetrating network qauv, tsim ib tug nruam polymer zaj duab xis nyob rau hauv lub pores, ntxiv dag zog rau cov kev sib raug zoo ntawm aggregates, thiab blocks ib co pores nyob rau hauv lub mortar, yog li qhov kev hloov kho tom qab hardening kev ua tau zoo ntawm mortar yog zoo heev dua li cov cement mortar.
Lub redispersible latex hmoov yog dispersed los ua ib tug zaj duab xis thiab ua raws li ib tug reinforcement raws li ib tug thib ob nplaum nplaum;kev tiv thaiv colloid yog absorbed los ntawm lub mortar system (nws yuav tsis raug puas los ntawm dej tom qab tsim zaj duab xis, los yog "secondary dispersion");zaj duab xis-forming polymer resin Raws li cov khoom siv txhawb zog, nws raug faib thoob plaws hauv lub tshuab mortar, yog li ua kom cov cohesion ntawm cov mortar.
