Yuav ua li cas los ntsuam xyuas cov hmoov polymer redispersible RDP?

Txoj kev sim rau cov khoom thiab viscosity ntawm redispersible polymer hmoov RDP, Thoob ntiaj teb tau siv dav los disperse polymer hmoov RDP nrog vinyl acetate thiab ethylene copolymerized emulsion hmoov, ethylene thiab vinyl chloride thiab lauric acid vinyl ester ternary copolymer hmoov, vinyl acetate thiab ethylene thiab cov rog fatty acid vinyl ester ternary copolymer hmoov, peb yam no los disperse polymer hmoov RDP hauv tag nrho kev lag luam, tshwj xeeb tshaj yog vinyl acetate thiab ethylene copolymer hmoov VAC / E, Nws nyob hauv txoj haujlwm ua tus thawj coj hauv ntiaj teb thiab sawv cev rau cov yam ntxwv ntawm redispersible polymer hmoov RDP.

Cov hmoov polymer uas yaj tau dua tshiabRDP muaj lub zog sib txuas zoo heev, txhim kho qhov yooj ywm ntawm cov mortar thiab muaj lub sijhawm qhib ntev dua, muab cov mortar zoo heev alkaline tsis kam, txhim kho qhov adhesion ntawm mortar adhesion, flexural zog, waterproof, plasticity, hnav tsis kam thiab kev tsim kho, hauv cov mortar tiv thaiv kab nrib pleb muaj zog dua.

Los ntawm kev paub txog kev siv polymer hloov kho los ntawm mortar, nws tseem yog qhov kev daws teeb meem zoo dua:

1, RDP yog ib qho ntawm cov polymers siv dav tshaj plaws hauv ntiaj teb.
2, Kev paub txog kev siv dav hauv thaj chaw ntawm architecture;

3, tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv rheological ntawm cov mortar (uas yog, qhov kev tsim kho uas xav tau);

4, nrog rau lwm cov monomer polymer resin muaj cov organic volatile matter tsawg (VOC) thiab cov yam ntxwv roj tsawg;

5, nrog kev tiv thaiv uv zoo heev thiab kev tiv thaiv cua sov zoo thiab kev ruaj khov mus sij hawm ntev;

6, nrog kev tiv thaiv saponification siab;

7, nrog rau qhov kub thiab txias dav dav (Tg);

8, nrog rau kev sib txuas zoo heev, kev yooj ywm thiab cov khoom siv kho tshuab;

9, yooj yim thiab zoo sib xws ntawm kev tiv thaiv colloid (polyvinyl cawv) ua ke.

Txoj kev nrhiav kom paub txog lub zog nplaum ntawm cov hmoov polymer redispersible RDP yog tus cwj pwm los ntawm cov txheej txheem txiav txim siab hauv qab no:

1, ua ntej, coj cov hmoov polymer redispersible RDP 5g rau hauv lub khob ntsuas iav, ntxiv 10g dej ntshiab thiab do rau 2 feeb, ua kom nws sib xyaw kom sib npaug;

2. Teem lub khob ntsuas sib xyaw rau 3 feeb thiab do dua rau 2 feeb;

3. Siv txhuam tag nrho cov tshuaj hauv lub khob ntsuas rau ntawm lub phaj iav huv kab rov tav;

4, muab lub phaj iav tso rau hauv DW100 qhov kub qis ib puag ncig simulation lub thawv simulation;

5, thaum kawg muab tso rau hauv 0 ° C ib puag ncig simulation tej yam kev mob rau 1 teev, tshem tawm lub phaj iav, sim qhov kev tsim zaj duab xis, raws li qhov kev hloov pauv ntawm cov polymer hmoov RDP redispersible siv lub zog sib txuas tus qauv.
