It is estimated that the total output of European glass fiber reinforced plastics in 2014 will reach 1.04 million tons.
Although the economic vitality of Europe has not yet fully recovered, with the continuous breakthrough of production technology, the continuous introduction of new composite materials and the continuous replacement of processing technology, the European glass fiber reinforced plastics market is still growing steadily. Recently, Sima Jie, director of the China Representative Office of the German Reinforced Plastics Processing Association, expressed the view that in 2014, the total output of glass fiber reinforced plastics in Europe is expected to reach 1.04 million tons. Rockwell hardness tester is the world's first designed based on the principle of rockwell hardness test, need only unilateral contact sample can test the hardness of the metal rockwell hardness tester, rockwell hardness tester measuring depend on magnetic head adsorption on the steel surface, don't need to support of sample, test precision up to the standard GB/T230, ISO6508, no less than desktop rockwell hardness tester. The Rockwell hardness test was first developed by Americans S.P. rockwell and H.M. Rockwell in 1914. In 1919 and 1921, they improved the design of rockwell hardness tester twice, which established the prototype of modern Rockwell hardness tester. In 1930, Wilson (C.H Wilson) updated the design, so that rockwell Hardness Testing methods and equipment more perfect. Our country has produced touch screen control and numerical display as well as curve display and automatic printing test data rockwell hardness tester. Rockwell hardness testing method is characterized by simple operation, rapid measurement, and can be read directly from dial indicator or optical projection screen or display screen. Along with Brinell and Vickers hardness testing, it has become one of the three most commonly used hardness testing methods Rockwell Hardness Tester,Digital Rockwell Hardness Tester,Rockwell Hardness Test Scale,Rockwell C Hardness Tester TROJAN (Suzhou) Technology Co., Ltd. , https://www.trojanmaterials.com
