Kev siv ntau yam ntawm dispersible polymer hmoov

Cov hmoov roj hmab yog ua los ntawm qhov kub thiab txias, kev kub siab, tshuaj tsuag kom qhuav thiab homopolymerization nrog ntau hom active-txhim kho micropowders, uas tuaj yeem txhim kho lub peev xwm sib txuas thiab tensile lub zog ntawm cov mortar. , zoo heev thaum tshav kub kub kev laus kev ua tau zoo, cov khoom xyaw yooj yim, yooj yim rau siv, tso cai rau peb los tsim high-zoo qhuav-siv mortar. Kev siv ntau yam ntawm dispersible polymer hmoov yog:

Adhesives: pobzeb adhesives, adhesives rau kev tsim kho thiab rwb thaiv tsev panels;

Phab ntsa mortar: sab nraud thermal rwb thaiv tsev mortar, hniav mortar;

Pem teb mortar: self-leveling mortar, kho mortar, waterproof mortar, qhuav hmoov interface tus neeg sawv cev;

hmoov txheej: txiv qaub-cement plasters thiab coatings hloov nrog putty hmoov thiab latex hmoov rau sab hauv thiab sab nrauv phab ntsa thiab qab nthab;

Filler: pobzeb grout, sib koom mortar.

Redispersible latex hmoovtsis 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; me me ntim ntim, lub teeb yuag, yooj yim rau siv; Nws tuaj yeem siv los ua cov khoom sib xyaw ua ke nrog cov khoom siv hluavtaws, thiab tsuas yog yuav tsum tau ntxiv dej thaum siv, 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.

Nyob rau hauv lub mortar, nws yog los txhim kho qhov tsis muaj zog ntawm cov tsoos cement mortar xws li brittleness thiab siab elastic modulus, thiab muab cov cement mortar zoo dua elasticity thiab tensile daim ntawv cog lus lub zog los tiv thaiv thiab ncua lub tiam 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 kev sib raug zoo ntawm cov aggregates thiab blocks ib co ntawm cov pores nyob rau hauv lub mortar. Yog li ntawd, cov mortar hloov tom qab hardening muaj kev ua tau zoo dua li cement mortar. tau zoo lawm.

Dispersible polymer hmoov yog dispersed mus rau hauv ib 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 (cov zaj duab xis 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 nqa tau muab faib thoob plaws hauv mortar system, yog li ua kom cov cohesion ntawm cov tshuaj khib.
