为了解决装饰砂浆普遍存在的泛碱难题,以可再分散乳胶粉(SWF-08)、羟丙基甲基纤维素醚(HPMC)、阻碱剂和憎水剂(SWR-100)为影响因素,以14 d拉伸强度和泛碱性为考核指标,采用单因素分析法优选出制备装饰砂浆的最佳配方。结果表明:各种物料对装饰砂浆抑制泛碱作用的大小依次为阻碱剂>HPMC>胶粉>憎水剂;当w(阻碱剂)=1.8%、w(HPMC)=0.4%、w(胶粉)=3.0%和w(憎水剂)=0.2%时,装饰砂浆的抑制泛碱作用最强,并且其拉伸强度较高。
In order to solve the ubiquitous problem of ubiquitous decorating mortar, the influencing factors were SWF-08, HPMC, SWR-100 , The 14 d tensile strength and ubiquitination as the assessment index, the best formula for the preparation of decorative mortar by single factor analysis. The results showed that: the inhibition of the efflorescence effect of various materials on the decorative mortar was followed by alkali-resistant agent> HPMC> powdered plasticizer> water-repellent agent. When w (alkali-resisting agent) = 1.8%, w (HPMC) = 0.4% (Powder) = 3.0% and w (water repellent) = 0.2%, decorative mortar inhibition of the role of the most outgassing, and its higher tensile strength.
