The construction technology of polymer mortar

Fujian polymer mortar is emerging in engineering in recent years a new type of building materials, and it is made of cement materials can be dispersed in the water of organic polymer. Simply put: refers to adding polymer adhesive mortar, so that the mortar and highly improve the performance of a kind of building materials. Pay attention to the differences and polymer concrete and polymer mortar aggregate. 1, the basic requirements and processing: basic level surface should be smooth, rough, clean, no oil, no float ash, dusting, empty drum, there should be no cracks. Construction before application of high-pressure spray on them and keep wet state, but can not have water. Interface bonding, can besmear brushs NingHeng brand polymer mortar interface treatment grout in advance. 2, material preparation, specifications according to water than the water mix, with a good ceramic tile seam filling grout should be confirmed at 0. 5 - Finished in 1 hour. 3, construction: in damp concrete base surface evenly over the first coating at the end of the nanjing polymer mortar ( Powder: water by weight ratio of 3:1) , coating and polymer cement mortar. TD - JS shoulds not be too great a construction area of high strength polymer mortar, article should be partitioned staggered construction, each area should not be greater than 10 m2, the interval of staggered construction should not be less than 24 hours. Layered construction, seam location should be staggered to each other. 4,TD - JS high-strength polymer mortar paving should immediately after hydraulic pressure and a smooth, should not be repeatedly put pressure. In case of bubbles should be punctured, the surface should be compacted. Facade or on the surface of the roof should be layered construction layer thickness is greater than 10 mm. The appropriate thickness of each layer of plaster for 5 - Before 10 mm, with a layer of touch when may lower the construction be carried out. 5 and maintenance: TD - JS high-strength polymer mortar after construction, the surface touch after drying should be spray curing careless or override, keep wet sacks, etc. The curing temperature is not below 5 ℃. TD - JS high-strength polymer mortar construction after 24 hours, covering plastic and wet curing 7 days, conditional can be timing sprinkling water on the surface.
