What is the difference between a shot blasting machine and sand blasting machine?

Image
  Shot blasting machine is generally used for regular shapes, etc., several blasting heads are up and down, left and right, high efficiency and low pollution. In the shipbuilding industry, shot blasting and sand blasting machines are commonly used. However, both the shot blasting machine and the sand blasting machine uses compressed air. Of course, it is not the floor shot blasting machine that has to use a high-speed rotating impeller. In shipbuilding and shipbuilding industries, floor shot blasters are generally used for steel plate pretreatment (removal of rust before painting); shot blasting equipment (ores used in repairing and shipbuilding industries) are mostly used for shaped ships or sub-parts. The function is to remove the old paint and rust on the steel plate and repaint it. In the shipbuilding and shipbuilding industry, the main function of shot blasting equipment and automatic sandblasting machine is to increase the adhesion of steel plate coating paint. In fact, t...

  water well drilling rigs Water well drilling rigs are easy to move, small in size, and high in work efficiency. They are fully hydraulically controlled for lifting, outriggers, lifting, and other processes. Drill pipes can be replaced without stopping the machine. It can meet various geological conditions such as soil, well-drilling sand, and rock pebble layers. Structure, equipped with high-power hydraulic motor, high torque, fast drilling speed. Water well drilling machine is suitable for complex formations such as soil layer, rock layer, pebble layer, cemented pebble layer, etc. Water well drilling rigs are widely used in foundation engineering construction of high-rise buildings, large bridge projects, water conservancy construction, farmland engineering, and other fields. Small water well drilling rigs are suitable for building pile foundations, high-tension line tower pile foundations, dam foundation drilling, drilling water wells, agricultural irrigation wells, and engin...

How are nitrile gloves produced?

Image
Nitrile gloves are mainly made by dipping nitrile latex, molding, vulcanizing, surface treatment, dust-free cleaning, and other processes. The specific production process is as follows: First of all, the material for making nitrile gloves is nitrile rubber, which is formed by the emulsion polymerization of butadiene and acrylonitrile. Then, the hand-washing mold: the hand-washing mold needs to be pickled first, washed first, alkali washed, and then washed. After washing the hand mold, it should be dried or dried before entering the next process. The third step is to impregnate the nitrile latex to shape the glove. That is, the hand mold is immersed in a container filled with nitrile, heated at a high temperature, and dried after forming the glove. Next, we need to prepare the gloves to curl to facilitate putting on and taking off the gloves. After the above steps, the nitrile glove has been formed, but it has not been successful. A key step is needed: chlorine washing. Chlorine cleani...
