The external insulation of the external wall is to put a thermal insulation coat on the building. This thermal insulation coat should not only keep heat, but also be beautiful. At present, my country’s external wall insulation system mainly includes expanded polystyrene board insulation system, extruded polystyrene board insulation system, polyurethane insulation system, latex powder polystyrene particle insulation system, inorganic vitrified bead insulation system, etc. External thermal insulation is not only suitable for heating buildings in northern areas that need heat preservation in winter, but also for air-conditioned buildings in southern areas that need heat insulation in summer; it is suitable for both new buildings and energy-saving renovation of existing buildings; renovation of old houses.
① The effect of adding redispersible latex powder to the freshly mixed mortar of the external wall insulation system:
A. Extend the working hours;
B. Improve the water retention performance to ensure the hydration of cement;
C. Improve workability.
② The effect of adding redispersible latex powder on the hardened mortar of the external wall insulation system:
A. Good adhesion to polystyrene board and other substrates;
B. Excellent flexibility and impact resistance;
C. Excellent water vapor permeability;
D. Good hydrophobicity;
E. Good weather resistance.
The emergence of tile adhesives, to a certain extent, ensure the reliability of tile paste. Different construction habits and construction methods have different construction performance requirements for tile adhesives. In the current domestic tile paste construction, the thick paste method (traditional adhesive paste) is still the mainstream construction method. When this method is used, the requirements for the tile adhesive: easy to stir; easy to apply glue, non-stick knife ; Better viscosity; better anti-slip. With the development of tile adhesive technology and the improvement of construction technology, the trowel method (thin paste method) is also gradually adopted. Using this construction method, the requirements for tile adhesive: easy to stir; Sticky knife; better anti-slip performance; better wettability to tiles, longer open time.
① The effect of adding redispersible latex powder on the freshly mixed mortar of tile adhesive:
A. Extend the working time and adjustable time;
B. Improve the water retention performance to ensure the hydration of cement;
C. Improve sag resistance (special modified latex powder)
D. Improve workability (easy to construct on the substrate, easy to press the tile into the adhesive).
② Effect of adding redispersible latex powder on tile adhesive hardening mortar:
A. It has good adhesion to various substrates, including concrete, plaster, wood, old tiles, PVC;
B. Under various climatic conditions, it has good adaptability.
