Inspection and analysis of six characteristics of silicon PU court materials

,
Silica ball court
Material water resistance inspection
Apply the paint on the cement block in multiple times to form a film thickness of 1 mm, leave it for a few days, then soak it in alkaline water for a few days. It is qualified if there is no delamination or hollowing.

Silicon court
Material adhesion check
Mix the molded paint into a sesame paste shape, apply the mixed paint to the two half-word mortar blocks, and leave it for a while. Bonding test, type ratio (high elastic powder glue medium elastic powder glue type is greater than or equal to the bonding index is qualified.

Material low temperature flexibility inspection
Wax the glass plate. Apply the paint mixed at the construction site on the glass plate in multiple batches to form a film thickness of 1 mm. After drying, remove it from the glass plate and place it indoors for (℃℃) days, and then cut it out. A strip of millimeters long and millimeters wide. Adjust the refrigerator temperature to ℃. Place the test piece in the refrigerator for 1 minute. Wrap the front and back of a round rod with a diameter of 1.5 millimeters. If there are no cracks, it is qualified. If there are cracks, it means that the emulsion is not soft enough at low temperature. .

Material thickness inspection
The paint film thickness inspection should use the needle puncture method to puncture three points per square meter, and use a ruler to measure the thickness of the paint film. Height, take the average value, and the film thickness should be greater than millimeters. Use a colored pen to mark the puncture for easy repair.

Material impermeability inspection
If If the conditions are not met, you can use visual inspection to check the waterproofing effect. The method is to apply the paint to the non-woven fabric in batches. After drying, the film thickness is (approximately) mm, and it is made into a slow box shape and suspended, but no dead corners are allowed , and then add alkaline water into the box. If there is no leakage, it is qualified.
Under certain conditions, use instrument testing. The method is to mix the paint in proportion and apply it on the glass plate in multiple times (glass The board is first waxed to a thickness of meters and left to stand for a day, then placed in an oven to bake at ℃ for an hour. After taking it out, place it for an hour and do a water-impermeable test. The water-impermeability is qualified if it remains for 10 minutes without leakage.

Inspection of material fracture elongation
During waterproofing construction, supervisors can go to the construction site to apply the mixed materials on the flat glass plate in multiple batches (the glass plate should be First, wax the film to a thickness of 1 mm, leave it for days, soak it in alkaline water for days, and then bake it in an oven at ℃ ± ℃ for an hour. Do a dumbbell-shaped tensile test, and the required extension retention rate reaches (without treatment). If it cannot be reached Standard, indicating that the proportion of emulsion added during construction is insufficient.
