Cov ntawv thov dav dav ntawm cov hmoov polymer dispersible

Cov hmoov roj hmab yog ua los ntawm kev kub siab, siab siab, tshuaj tsuag kom qhuav thiab homopolymerization nrog ntau yam micropowders uas ua kom zoo dua qub, uas tuaj yeem txhim kho lub peev xwm sib txuas thiab lub zog tensile ntawm cov mortar. , kev ua haujlwm kub zoo heev, cov khoom xyaw yooj yim, yooj yim siv, tso cai rau peb tsim cov mortar qhuav sib xyaw zoo. Cov ntawv thov dav dav ntawm cov hmoov polymer dispersible yog:

Cov nplaum: cov nplaum rau pobzeb, cov nplaum rau kev tsim kho thiab cov vaj huam sib luag rwb thaiv tsev;

Cov tshuaj khib phab ntsa: cov tshuaj khib rwb thaiv tsev sab nraud, cov tshuaj khib kho kom zoo nkauj;

Cov tshuaj khib hauv pem teb: cov tshuaj khib uas nws tus kheej siv tau, cov tshuaj khib kho, cov tshuaj khib uas tsis ntub dej, cov neeg sawv cev rau cov hmoov qhuav;

Cov hmoov txheej: cov plasters lime-cement thiab cov txheej txheej hloov kho nrog cov hmoov putty thiab cov hmoov latex rau sab hauv thiab sab nraud phab ntsa thiab qab nthab;

Cov khoom siv: pobzeb grout, pob zeb sib koom ua ke.

Cov hmoov latex uas yaj tau dua tshiabtsis tas yuav khaws cia thiab thauj nrog dej, txo cov nqi thauj mus los; lub sijhawm khaws cia ntev, tshuaj tiv thaiv kev khov, yooj yim khaws cia; ntim me me, lub teeb yuag, yooj yim siv; Nws tuaj yeem siv ua premix hloov kho nrog cov khoom siv hluavtaws, thiab tsuas yog xav tau ntxiv dej thaum siv, uas tsis tsuas yog zam kev ua yuam kev hauv kev sib tov ntawm qhov chaw tsim kho, tab sis kuj txhim kho kev nyab xeeb ntawm kev tuav khoom.

Hauv cov tshuaj khib, nws yog los txhim kho qhov tsis muaj zog ntawm cov tshuaj khib cement ib txwm muaj xws li brittleness thiab siab elastic modulus, thiab muab cov tshuaj khib cement zoo dua thiab tensile bond zog los tiv thaiv thiab ncua lub cim ntawm cov kab nrib pleb cement. Txij li thaum cov polymer thiab cov tshuaj khib tsim cov qauv network interpenetrating, ib zaj duab xis polymer txuas ntxiv tau tsim nyob rau hauv cov pores, uas txhawb nqa qhov kev sib txuas ntawm cov aggregates thiab thaiv qee qhov pores hauv cov tshuaj khib. Yog li ntawd, cov tshuaj khib hloov kho tom qab hardening muaj kev ua tau zoo dua li cov tshuaj khib cement. tau zoo dua.

Cov hmoov polymer uas tawg tau raug faib mus rau hauv ib zaj duab xis thiab ua haujlwm ua ib qho kev txhawb nqa ua ib qho nplaum thib ob; cov colloid tiv thaiv raug nqus los ntawm lub kaw lus mortar (zaj duab xis yuav tsis raug rhuav tshem los ntawm dej tom qab tsim zaj duab xis, lossis "kev tawg thib ob"); cov tshuaj polymer ua zaj duab xis Raws li cov khoom siv txhawb nqa tau faib thoob plaws hauv lub kaw lus mortar, yog li ua rau kom muaj kev sib koom ua ke ntawm cov mortar.
