Dispersible polymer powder performance of external wall insulation and decorative effects


tc anti-aging anti-aging wall to do the same experiment can prove it. Aging experiments were carried out according to EOTA draft,tory burch outlet, a total of 80 cycles, each cycle consists of the following three steps: 1) 70 ℃,######## oakley sunglasses, relative humidity 10%,knock off oakleys, 3h; 2) 15 ℃, rain,MBTシューズ 販売店, 1h; 3) 15 ℃, 2h. Visual comparison of test results and found that the use of powder B and C in the bottom of powder with good anti-aging, the results show that the use of hydrophobic dispersible polymer (fine cement), Tangshan Jidong Cement Co., Ltd. Sanhe production. Performance indicators in Table l. 1.2 Test methods produce size 40n1n1 × 40rnn1 × 401Tllql of slag cement paste specimens and specimens of pure cement paste, the mixture ratio shown in Table 2, the water-cement ratio of 0.3, forming curing were tested 16h after , 3d, 28d, 56d, 90d age compressive strength and chemical combination of water content and the XRD analysis. Table 2 The test cement ratio P. () 42.5RP1I425RPII525R name A1A2A3B1132133c1c2 (23 0510O51OO5102 slag cement 1o0959010095901OO9590 2.1 Compressive strength test results and discussion of the age of cement paste compressive strength test results are shown in Figure 1 to Figure 3.1) replaced in the ground slag amount of 5% and 10%, the compressive strength of hardened slurry increased early, higher than the control group is not mixed, and not mixed with the late strength close to the blank group. Ground slag has a high fineness, and its degree of polymerization of silicon-oxygen tetrahedron is low,ed hardy uk, its ...] ...] ...] ...] ...] ...] ..., ..., an] the importance of H powder as binder. 3 Conclusion bottom of the EIFS system has an important role in underlying the use of dispersible polymer powders can significantly improve the performance of all aspects of EIFS and quality. The results show that: a suitable hydrophobic dispersible polymer powder (powder B), can improve the protective layer and the adhesion between the EPS board, and greatly improve the mechanical stability of the system (flexible, no cracking); with hydrophobic low of dispersible polymer powders overall good performance. In addition, the dispersible polymer powder to make cement mortar modified hydrophobic evenly distributed, so that the bottom of the water absorption decreased. Experiments conducted in UEAtc wall that different redispersible powder underlying the mechanical stability vary widely.
