Prerequisite work for the construction and laying of plastic track in track and field fields

The ambient temperature of the plastic track
The construction site should be controlled at ℃~℃. Avoid operating at ambient temperatures below ℃ or above ℃. The relative humidity should be controlled below %. The foundation must be smooth and clean. The amount of catalyst should be adjusted according to the temperature and relative humidity. Control the curing speed appropriately. When storing color paste and prepolymer, the lid of the bucket should be tightened, and the water content should be tested before use. Use it after passing the test. The water content in the foundation should also be controlled to avoid bubbles after gelling. All this is to ensure The runway is laid on a qualified foundation.

Test before paving construction: First, sort the two-component slurry and prepolymer used in the polyurethane plastic track
according to the production batch number. Then samples were taken for gel-forming tests and wire-drawing gel-forming tests according to the on-site environmental conditions. If it is found that the gelling speed of a certain batch of slurry is too slow, adjust the amount of catalyst to adjust the gelling speed to achieve a suitable gelling speed. If it is found that a certain batch of slurry does not form gel, adjust the amount of prepolymer to improve it to achieve gel formation. If it is found that foaming occurs in a certain batch of slurry or a certain barrel of slurry during the gelling process, the batch of slurry or this barrel of slurry will be stacked separately and returned to the factory for rework.

Nailing the molding strips: Nail the wooden molding strips wrapped with polyethylene film along the drawn bottom line according to the pre-arranged area. The mold strips must be flat and nailed to the foundation to prevent material leakage during the construction of the plastic track.

Bottom line of measurement and mapping: In order to reasonably arrange the daily paving workload, we must first measure and draw the dividing lines according to the set plan, divide the entire track and field into strips, and then press the strips and blocks. Carry out paving. In order to ensure smooth drainage and few joints, plastic track construction generally adopts the construction procedure of first inner ring and then outer ring.

Preparation of finished products: Calculate the required semi-finished products based on the pavement area of the plastic track
project, hoist the required slurry and prepolymers to the operating table respectively, and arrange them neatly according to the batch number. Place the required black colloidal particles and catalyst in appropriate locations on the operating table.
