Lub luag hauj lwm ntawm redispersible latex hmoov nyob rau hauv mortar khoom

1. Dab tsi yog lub luag haujlwm ntawm redispersible latex hmoov hauv mortar?

Teb: Lub redispersible latex hmoov yog molded tom qab dispersion thiab ua raws li ib tug thib ob nplaum los txhim kho daim ntawv cog lus; cov kev tiv thaiv colloid yog absorbed los ntawm lub mortar system (nws yuav tsis hais tias yuav tsum tau puas tom qab molded. Los yog dispersed ob zaug); molded polymerization Lub cev resin raug faib thoob plaws hauv lub mortar system raws li cov khoom siv txhawb zog, yog li ua kom cov cohesion ntawm cov mortar.

2. Dab tsi yog lub luag haujlwm ntawm redispersible latex hmoov nyob rau hauv ntub mortar?

Teb: Txhim kho kev tsim kho; txhim kho fluidity; nce thixotropy thiab sag kuj; txhim kho kev sib raug zoo; ncua sij hawm qhib; txhim khu kev tuav dej;

3. Dab tsi yog cov haujlwm ntawm redispersible latex hmoov tom qab mortar kho?

Teb: nce tensile zog; txhim kho khoov zog; txo elastic modulus; nce deformability; nce cov khoom ntom ntom; nce hnav tsis kam; nce cohesive zog; Nws muaj hydrophobicity zoo heev (ntxiv hydrophobic roj hmab hmoov).

4. Dab tsi yog lub luag haujlwm ntawm redispersible latex hmoov nyob rau hauv cov hmoov qhuav mortar sib txawv?
