In the hot summer, the “wading†toys began to sell well, especially the toy water guns were more popular among children. However, some netizens broke the news recently. In Shaanxi and Shandong, children were hit by the water from the toy water gun, causing retinal contusion. How big is the power of the water gun? The reporter found that the pressurized water gun is dangerous, and the sprayed water can arbitrarily break through the printing paper within 1 meter. If the distance is closer, it can even penetrate 0.2 cm thick cardboard. Ophthalmologists suggest that a close-up shot of the pressurized water gun may cause eye damage or even decreased vision in the child. Parents should not buy a pressurized water gun for their child. Market visits, great range, far-pressed water guns sell best A few days ago, the reporter saw in the two wholesale markets of Hongqiao and Tianyi that the water guns sold on the market mainly consisted of pressurized and non-pressurized. The pressurized water pistol has a water storage tank at the end, which can pressurize the gun body through the front end of the inflator to compress the air in the water gun, and pull the trigger to spray the water column with pressure, generally can spray water to 10 The meter is even 20 meters away. The ordinary non-pressurized water gun only relies on the compression of the small gas tank at the trigger, and the general distance will not exceed 5 meters. According to the business introduction, the pressurized water pistol is “stronger†and is most popular among children and sells best. These best-selling water gun toys are generally priced between 15 and 60 yuan. The reporter found that except for a medium-sized pressurized water gun marked with the production of the company, almost no other brands. The foreman of a toy factory told reporters that because the profits of water guns are not high, many companies except for individual manufacturers are produced in a short period of six months or a year according to the materials or market conditions, so there are few special brands. Experimental preparation 6 water guns: two large, medium and small (for the convenience of recording, the following are marked with a 1-6 gun). Other equipment: To verify its destructive power, the reporter prepared A4 printing paper, cling film and cardboard with a thickness of 0.2 cm. Jet test large pressurized water gun sprayed nearly 30 meters at the farthest When buying water guns, parents and merchants told reporters that how far they can spray is an important criterion for children to “measure†the quality of water guns. To this end, the reporter measured the jet distance of six water guns. As a large pressurized water gun, the final drop point of the water column sprayed by the No. 1 gun and the No. 2 gun is more than 25 meters away from the reporter, and the final distance of the two small non-pressurized water guns is less than 10 meters. Destruction experiment The reporter filled six water guns with water and pressurized the pressurized water gun. After pressing for 50 times, a spray break test was performed on four sheets of printing paper, wrap film, and cardboard, respectively. It was found that the pressurized water gun can instantly break the A4 paper like an arrow within 1 meter. When moving to 5 meters, it takes more than 5 seconds for the No. 1 water gun and the No. 2 water gun to penetrate the paper. At this time, the paper has been saturated and the texture is very soft. It can be seen that the water column has been significantly reduced. The No. 3 water gun is slightly weaker than the large water gun, and can damage the A4 paper within 1.2 meters. However, the water flow of the No. 4 water gun is relatively dispersed and the penetration is not strong, so it has little effect on the cardboard and the cling film. The No. 5 and No. 6 water guns are subject to the volume of their own gas tanks and have less power. The No. 5 water gun has a large gas tank and can penetrate the A4 paper at a distance of 0.2 meters. Zhejiang Shengfa Textiles Printing&Dyeing.,ltd , https://www.chzjsf.com
