Supply mews cutting disc polished pieces

 Mews cutting discs are widely used in electric power, petrochemical, metallurgy system piping and boiler-site field service repair work. Especially for power plants in the water wall tubes, boiler heat exchanger tubes, the provincial gas pipe field replacement effect is quite abrasive manufacture  good, especially for power plants, petrochemical, and other open flames contain flammable gas is not easy to move the on-site cutting tube replacement. Especially suitable for pipe spacing narrow, high-altitude site cutting corners and tube replacement. PFERD thin cutting discs lead the current application of the trend, widely praised by users. The thickness of 0.8,1.0,1.6 mm  standard abrasives cutting disc has the following characteristics: cutting force performance, manual control easy, straight cut, no jitter. Today kids on science activities "slow and fast paper paper" First, I let the children do the test with a white paper, take a look at pieces of paper fall look. Then use two different colors of paper, so that children comparison and also fall, which one is faster. Finally, let children make paper dragonflies, observe the whereabouts of the way, and then compare and paper which fall faster. Children in the cutting disc  experimental exploration of perception and the speed of paper fall to experience the fun of exploring, knowing the paper made of paper fall fastest dragonflies, children are scrambling to express their views. Activities and achieved good results. I think that scientific activity in the kindergarten activities can not be underestimated, so that children learn not only scientific knowledge, but also to stimulate the children's desire to explore.
