Product Introduction
1.Product Introduction
Propylene emulsion mortar is a polymer modified mortar configured with acrylate copolymer emulsion and cement mortar according to a certain ratio. It can improve the internal stress state of cement mortar, can withstand deformation to reduce the stress of cement stone, limit and reduce the generation and expansion of micro-cracks.

3. Construction Process
Propylactic mortar construction is convenient, simple preparation, can be used manually and mechanical spraying two construction methods, the specific steps are as follows:
Propylactic mortar construction is convenient, simple preparation, can be used manually and mechanical spraying two construction methods, the specific steps are as follows:
Base surface treatment:
chiseling away the old concrete surface spalling layer, rinsed with water, to ensure that the base surface is clean and solid; if there is corrosion of steel reinforcement on the base surface, the reinforcement must be descaling and rust inhibition treatment.
Mixing of propylene emulsion mortar:
Mixing of propylene emulsion mortar:
according to the proportion provided by the manufacturer, mix well, weigh accurately, do not arbitrarily increase the amount of water used, and the finished material should be used as soon as possible.
Construction:
Construction:
Generally use acrylate emulsion to moisten the base surface, not too much, so as not to form a polymer film affecting the construction effect; the construction process should be wiped in layers, the thickness of each layer should not be more than 5mm, compaction, should be wiped in one direction, not back and forth for many times.
Maintenance:
Maintenance:
After 4h, the propylene emulsion mortar should be maintained by sprinkling water or covering film; in direct sunlight or windy location, attention should be paid to shading and moisturising.
4.Usage
Packing: Each group contains 2 bags of mortar (50kg / bag) and 1 barrel of emulsion (16kg / barrel).
