How to detect the pattern water belt?

The pattern water belt production line is made of high-strength polyester and PVC synthetic materials. It is the ideal water-saving irrigation tool in China. The quality of the patterned water belts on the market is uneven, mainly by the view of our buyers. Below Hengxiang Plastic Machine Xiaobian to share with you a few test pattern water belt rules:

1. Sample sampling work, the length of the sample is not shorter than 1.20 meters. The number of samples is three.

2. Check the inner diameter of the sample and measure the inner diameter of the water belt with a plug gauge. Fire hose test method When measuring the inner diameter, first cut the ends of the sample, and then measure the two ends with a plug gauge.

3. Weigh the weight of the sample per unit length. The ratio of the weight to the length of the sample is the weight per unit length of the water belt.

4. Water consumption test water is urban tap water. The water temperature is 15 to 30 °C.

5. Folding blasting pressure, after measuring the water seepage volume, the sample is folded from the center, so that the samples are close together and fixed. The pressure is raised evenly to the specified folding burst pressure, and the sample is kept for 5 seconds, and the sample must not be broken. The boost time is 30 to 60 seconds.

6. The blasting pressure of the curved state. After the pressure of the water seepage is measured, the sample is bent into an arc with an inner radius of 700 mm. A flange of the specimen should be placed outside the arc. The pressure is raised evenly to the specified tortuous burst pressure and the specimen must not be broken. The boost time is 30 to 60 seconds.
