Preparation before bonding:
1. The bottom surface of the turf to be bonded, the non-woven fabric, the joint cloth, etc. must be cleaned, and the surface is dry and free of moisture.
2. the ambient temperature should be selected above 5 °C construction is appropriate, and it is not suitable to work under rain and wet weather, otherwise it will lead to too long bonding time or even non-stick phenomenon.
Specific construction process:
Gluing: It is required to use a brush to apply a thick and even surface on the surface. Do not apply glue repeatedly, otherwise blistering may occur or even fall. The base fabric is coated with glue, and the thickness of the glue is strictly controlled. Note that the speed of the glue should be appropriate. When applying the glue, it should be applied to the two bonding surfaces that are bonded.
Adhesive: According to the actual temperature, humidity, pressure and other conditions at the time, the effective control of the open time. Generally, within 10-30 minutes after the application of the glue, the glue reaches 80% to dry and the hand is not sticky. One-time alignment is required for bonding. Never move the bonded object back and forth after bonding.
Pressurization: After bonding, remove the surface debris, and use a special rubber hammer to hammer the two sides from the bonding point to make the surface fully contact with the compact and the bonding is firmer.
Curing: The curing time is generally three days, and the final strength of the test is generally ten days. Therefore, it is necessary to pay close attention to its maintenance during curing to avoid excessive exposure, flooding and movement to achieve the best bonding.
After the bonding, the turf cut pieces of the site are cleaned before the quartz sand and rubber particles are sprinkled.
