Magnesium aluminum silicate thixotropic lubricant for mortar
Premixed mortar refers to the wet mixed mortar or dry powder mortar produced by a professional manufacturer. It realizes industrial production, ensures the stability of quality from the source, and has many advantages such as good operability, less pollution on site, and effective improvement of project progress. The ready mixed (wet mixed) mortar is transported from the production point to the site for use, just like the commercial concrete, it has higher requirements on its working performance. It is necessary to ensure a certain operational time. After mixing with water, before the initial setting, the ready mixed (wet mixed) mortar should have sufficient workability and be able to carry out normal construction and operation. In order to make the performance of ready mixed mortar meet the requirements of specifications and construction, mortar admixture is an essential component. Magnesium aluminum silicate thixotropic lubricant and cellulose ether are common water retention thickeners in mortar. Cellulose ether has good water retention property, but there are some problems, such as high price, high content, serious air entrainment, which greatly reduces the strength of mortar; the price of magnesium aluminum silicate thixotropic lubricant is low, but the water retention property is lower than that of cellulose ether, and the drying shrinkage value of the prepared mortar is larger, The adhesiveness decreased.
1.Adding magnesium aluminum thixotropic lubricant into mortar can significantly improve the workability and workability of mortar, and can better improve the overall quality and characteristics of all kinds of mortar. The good performance of magnesium aluminum silicate is mainly reflected in the following aspects: 1. Good suspension. It has good wrapping property for sand and gravel (especially for machine-made sand suspension effect is remarkable), prevent mortar bleeding and segregation, prevent machine spraying mortar from settling and blocking pipe, which can significantly improve the overall homogeneity of mortar.
2.Excellent thixotropy. It has remarkable anti sagging performance. It can improve the thixotropy and rheology of the system. This product is dispersed in all kinds of mortar when it meets water, and forms grid structure rapidly by hydration. When the mortar is still, it can effectively improve the foundation viscosity of mortar system and form the yield value with anti sagging effect.
3.Excellent lubricity. It can effectively reduce the friction resistance between the materials in the mortar, and make the mortar form the overall smooth effect. The construction is light, and it is even more powerful for the pumping and mechanical spraying mortar.
4. Excellent synergetic thickening and water retention. When used with cellulose, the workability of mortar can be improved, the mortar can be sticky but not thick, round and smooth, and the amount of cellulose can be partially reduced in some systems.
5. Magnesium aluminum silicate can kill starch ether in machine sand blasting slurry, and has its own advantages with starch ether in special mortar products such as tile glue. However, magnesium aluminum silicate has better material and environment tolerance, and its mortar saturation and anti bleeding effect are better than starch ether.
