Attentions of Putty Powder in Summer Construction
Into the June, the weather gradually hot, the sun also began to vicious up, walking on the road to the suburbs, roadside large golden fields of wheat, bursts of dry wind blowing over, wheat undulating rustling. Full of the ears of the spike son, as if bent waist respectful humility waiting to reap that moment, at this point in the distance has been faintly heard the roar of the Harvester, peasant friends on the scorching sun hard laborer. At this time, we as building materials industry to withstand the hot sun successfully through the summer putty powder construction. Hot and humid weather in summer.
Improper construction will bring about the influence of putty powder, how is the correct way of construction in summer?
First: Putty construction environment is the temperature in 5-35 ℃, air humidity is less than 85%, humidity is less than 10%.
Summer exposure, the temperature is too high, not only the substrate is easy to dry, water absorption fast, the strong solar light will also accelerate the putty powder evaporation speed. So that the surface of the putty after the construction of drying too fast, the emergence of skin, powder and the phenomenon of cracking after the batch.
High-temperature drying environment, you can use the Wall interface agent to close the substrate, or in the putty before the construction, two hours in advance with water moist wall, putty layer completely dry and then sprinkle water conservation.
1. according to the proposal to add water stirring, static 10 minutes after the ripening of stirring again;
2. has been allocated good putty powder in two hours of the proposal to run out;
3. avoid high-temperature environment and strong direct sunlight under the construction.
Secondly: the water content of the grassroots is 10%; no powder, no sand, no empty drums, no stripping, no lime burst point and no adhesion of the old coating, etc. surface no dust, no flotation, no oil, no rust, no mold point, no salts precipitate and moss and other miscellaneous.
