Rally Detection Video
Tensile Resistance
In a test environment of 20 degrees, put multiple cut shingles into a tensile testing machine, and stretch at a limited moving speed of 100mm/min until the shingles break, showing that the transverse tensile force is above 500N
Sticky Video
Adhesive Glue
Cut 3 samples from the self-adhesive part of the shingles, clamp the samples with iron clamps, hang them vertically in an electric heating thermostat, set a temperature of 75℃, and take out the samples after one hour, showing that the adhesive glue slip position is not up to 2 mm
Color Sand Fading Detection Video
Discoloration
Put out 20g of colored granules for SEETON and other brands of colored granules into a glass container, respectively pour 5% dilute hydrochloric acid until the colored granules is immersed, and stir, heat them together for one hour, then wash the colored granules and dry it , Inferior colored granules has faded seriously, SEETON colored granules has almost no fading
Waterproof Detection Video
Waterproof
Cut 3 round samples from the shingles, mix white sugar and methylene blue and dry, match with filter paper glass to simulate rainwater environment, experiment for 12 hours, change the color of the filter paper to reflect the waterproofness of the shingles
Color Sand Adhesion Video
Adhesion
Cut 3 samples at the bottom end of the asphalt shingles, place them in an experimental environment at 20°C for 24 hours, and fix the samples on the scrubbing machine. Use the load brush to brush back and forth 50 times to observe the sand removal.
Nail Pullout Resistance Video
Nails Resistance
Cut 10 samples at the position of the asphalt shingle nails, insert the nails and place a special clamping device, set a constant speed at 100mm/min to pull until the nails are pulled out, collect 10 sets of data for analysis
High Temperature Resistance Video
Pressure Resistance
Cut 3 samples at the place where the asphalt shingles overlap each other, put them in an electric heating thermostat, press the iron ingot, adjust the temperature to 50℃, open and take out after 12 hours, the three samples are not bonded
