Test method of a continuous mist spray bottle
(1) The first is the appearance of the plastic spray bottle: refer to the visual inspection at a distance of about 40 cm under standard light sources, or for 3 seconds at a distance of 50 cm under natural light sources.
(2) Specifications and dimensions: use a general measuring tool or a special measuring tool with an accuracy of 0.02mm for inspection.
(3) Weight and pump output: check with an electronic balance with a precision of 0.01g.
(4) Pump output of small plastic spray bottles: use water as the test content, first, start the spray head/foam pump more than 5 times to ensure that the spray/pump output is stable, then start to press the spray head/pump head 10 times continuously, Weigh the average of the total weight of the 10 times of spray/pump water.
(5) Number of air pressures/number of first sprays: use water as the test content, test at a pressing frequency of once per second, and calculate the number of pressings from the start of pressing to the start of spraying (including the first time of spraying).
(6) Down pressure: the maximum pressure when the pressure head is pressed to the screw threading position or the position reached by normal use at a constant speed.
(7) Unscrewing force of the indenter: the maximum torque for unscrewing the indenter at a constant speed.
(8) Adhesion of decorative fastness of electroplating, spraying, sandblasting layer, etc.: The decorative fastness is divided into 25 small squares of 1mmX1mm with a blade, and 3M tape is used to stick it on the cut-out part, and one minute later, in the direction of 45 degrees Quickly tear off the tape and check the degree of peeling (if it is in a grid, only partially torn off the paint surface, record it as 1/2 grid if the entire surface of a grid is torn off, count as 1 grid).
