QB/T3635-1999
This standard extends the original professional standard ZBY28006-19886 polyvinyl chloride (2VC-U) skirting board, and is converted into standard number ×QB/3635-1999 through the publication of the State Light Industry Bureau No. 1993112, and the content remains unchanged. This standard is based on the Su Standard Factory 0 1911-77 "Technical Specifications for Polyvinyl Chloride Strip System 3". This standard was proposed by the Industry Management Department of the State Bureau of Light Industry: This standard was drafted by the National Plastic Products Chemical Technical Committee. This standard was drafted by Tianjin Material Research Institute. The main drafter of this standard is Wang Honghuang. From the date of implementation of this standard, it will replace the original light industry standard ZBY28006-98 Hard Polyethylene (PVC-U) Skirting Board, and the light industry standard of the People's Republic of China Hard Polyethylene (PVC-UJ) Skirting Board QB/T 3635-1999, which replaces QB/T 7.RY2200-18. This standard specifies the classification, technical requirements, test methods and inspection rules for hard polyvinyl chloride (PYL-U) skirting boards. This standard applies to ethylene-based panels (hereinafter referred to as ethylene-based panels) made of ethylene resin as the main raw material and molded by anti-aging.

Test method
5.1 Test method
QB/T3635—1999
The samples used should be prepared from the test tube. 5.2 Condition of the sample If there is no special provision for the standard environment of the test, the test sample should be placed at 23°C for more than 4 hours, and then the test should be carried out in this environment. 5.3 Determination of size difference between standard and standard sizes.
Use a special caliper with a diameter of 0.2mm to measure. 5.4 Determination of length and width
Use a steel tape measure with a diameter of 1m or a tool with equal accuracy to measure. 5.5 Determination of appearance
Under self-heating light, the sample is subjected to a drop at a distance of 400-509mm from the foot plate. 5.6 Determination of Vicat melting point
Perform according to CB1633. The heater is heated at a speed of A, and the sample is subjected to a static load center A. 5.7 Determination of longitudinal shrinkage
5.7.1 Trial
Use the method of cutting to cut a 20+0 device board. 5.7.2 Squeeze||t t||This number is the actual R5.7.3 Test procedure
Draw two lines along the length direction of the sample at 23+1mm, measure the maximum distance, guess D, mm, and place it flat on the powder plate. Then take the test plates out of the oven, cool to , measure the standard distance, and confirm. 5.7.4 Calculation and expression of the test potential
The longitudinal shrinkage is calculated by the following formula:bZxz.net
Longitudinal shrinkage standard, %:
The distance between the longitudinal line and the plate after the object moves,
The result is expressed as the arithmetic mean of the main samples. 5.8 Determination of the effectiveness of the test
Continue to 240:
5.9 Determination of the ball pressure
According to GR398.
5.10 Drop impact test (extended)
5.10.1 Sample
Mechanical method: Sample thickness equal to 2 times of sample thickness, but not less than 1mm, test number 10.

.10.2 Apparatus
QB/T3635—1999
Drop impact test machine; ball, mass 1 kg5.10.3 Test conditions
After the sample is placed at -101A for 4a, it is immediately tested at a temperature of 2±2°C within 10s.
5.10,4 Test procedure
Put the test piece on the test bench, and place it on the center of the test piece with a mass of 1k, 3m away from the guide rail
5.1.5 Evaluation of the test potential
The test piece will be considered unqualified if it has cracks after impact: 6 Inspection rules
