Now in order with the needs of the community, most kindergartens have begun laying artificial turf, let us look at the laying of artificial turf nursery precautions and requirements:
Common ground-based artificial turf nursery has two categories: asphalt base, cement foundation, gravel base, using the type which is mainly used by the local climate and environment and budget decision time, especially for large temperature difference between the north and low winter temperatures in the climatic environment , but also because of its high cost, for the warm and humid environment is not the most appropriate basis for the type of gravel base because of its simple construction, low cost, rapid drainage, more common in the South, but because of the difference between its rigidity and stability after prolonged use of prone foundation loose, resulting in uneven basis; therefore, in most regions of the country, cement concrete foundation became economical and practical, very high cost of artificial turf nursery base type.
The first step: to be bonded shall kindergarten artificial turf artificial turf nursery floor clean, dry and free of moisture and the surface should be selected ambient temperature above 5 ℃ construction is appropriate, moreover, not construction in the rain and Meiyu weather. otherwise it will lead to long time or even cause the adhesive stick phenomenon.
Step Two: Glue: Requires brushing the surface with the applicator in uniform thickness, can not be repeated kindergarten artificial turf adhesive, otherwise there will be blistering, or even fall. Strictly control the thickness of the glue, attention should be appropriate speed glue, glue were applied when the two bonding surfaces to be bonded.
Sticky and: According to the actual impact of the prevailing temperature, humidity, air pressure and other conditions, the reasonable control of air-curing time. Generally within 10-30 minutes after the glue, mortar reach eight or nine into a dry non-stick hand touch is appropriate. When the cement bonding alignment requires a one-time, must not stick and later moved back in the bonded objects.
Pressure: After re-bonding, remove the surface debris from the adhesive force at the real hammer to both sides, so that full contact dense surface bonding stronger.
Curing: Kindergarten artificial turf curing time is generally three days, testing the ultimate strength is generally ten days. It should be noted during curing maintenance, avoid exposure, flooding and movement, have to achieve the best bonding.
During the construction of artificial turf nursery when needed attention; construction, not the adhesive glue exposed for too long, due to solvent evaporation will cause the adhesive too large to construction. If the temperature is too low, the available hot water heating to the 15--20 ℃, you can restore the original state, and the same performance.
