Product introduction and characteristics
GH-302 Polymer anti crack mortar is also known as insulation covering mortar and plastering mortar. Our company has introduced German technology, combined with the current situation of thermal insulation in China, and adopted the selection of Olympic * * * cement , high quality Quartz sand Aggregates, added with polymer cement imported from Germany, combined with various additives, through biaxial gravity free particles Mixer Powdered building materials products mixed together. The quality of thermal insulation mortar directly affects the use effect and service life of the entire thermal insulation system. The thermal insulation system with thermal insulation overlay mortar effectively solves the problem of External wall insulation It has such problems as heat preservation, heat insulation, wind pressure resistance, fire prevention, freeze thaw resistance, water repellency, weather resistance, flame retardancy, air permeability, cracking, etc. It also has the advantages of good flexibility, high product bonding strength, good waterproof and crack resistance, convenient operation, easy control, etc., which can ensure long-term use performance, environmental protection and safety.
Scope of application
one Used for base plastering of polystyrene board and extruded board insulation system built in large formwork.
two It is used for the plastering of polystyrene insulation board and extruded board. It is used together with alkali resistant glass fiber gridding cloth to form a smooth surface layer.
Usage and precautions
one Base cleaning: firstly, the floating ash, floating soil and oil stain on the surface of polystyrene board shall be removed and polished.
two Preparation of mortar: polymer mortar and water 4:1 In a clean mixing bucket, put proper amount of clean water into the dry mortar slowly, and mix it evenly with a mechanical mixer after soaking. The mixed material shall be left standing 10min Then stir again to form a viscous slurry. The prepared materials shall be protected from the sun and wind, and the amount of materials allocated at a time shall be controlled to be used up within the operable time. After the operable time, no water (or glue) shall be added for use.
three Paste alkali resistant glass fiber gridding cloth: evenly scrape and coat the mixed mortar on the insulation board about 2-3mm Thick, and then press the glass fiber mesh into the mortar with a trowel. After hardening, the trowel can be used to conduct the second layer of facing mortar until the mesh cloth is completely covered. The overall thickness of mortar and fiberglass mesh outside the insulation board is 3-5mm 。 System drying twenty-four The next process can be started in hours.
four The ambient temperature and base temperature at the operation site shall not be lower than five ℃, wind force not greater than five Grade II, construction in summer should avoid direct sunlight, and construction cannot be carried out in rainy days to prevent rain from washing the wall under construction.
Technical indicators
Packaging and storage
one Package specification: 25kg/ Bags and 40kg/ Bags, plastic film paper bags lined with plastic bags, double-layer moisture-proof packaging.
two In the dry and clean warehouse, to avoid rain and moisture, the caked agent cannot be used, so as not to affect the use effect.
three Shelf life six Months.
