Velcro disc is an abbreviation of sandpaper, a customary name. Velcro disc is also sandpaper. It is a conversion product of sandpaper. Its shape is a positive circle. It is flocked with sandpaper roll , and then put it on the stamping machine for stamping with *** circular die. The stamped product is velcro disc.
Sanding disc can be divided into two types according to the lamination: back glue disc sand and back velvet disc sand (also known as self-adhesive disc sand and brushed disc sand). The fluffed disc sandpaper can be non hole fluffed disc sand paper or hole fluffed disc sand paper. The velcro disc with holes is convenient to discharge waste chips from the holes when grinding objects, so as to improve the grinding efficiency. There are other classification methods. For example, according to the size, the common disc sands are 100mm, 115mm, 125mm, 150mm, 180mm and 215mm in diameter, and the diameter area of disc sands that can be used is 23mm --- 235mm.
According to the sand surface of disc sand, the common ones are white sand disc sand, red sand disc sand, yellow sand disc sand, black sand flocking disc sand, blue sand disc sand, green sand disc sand, grid flocking sand. And classified from the raw materials of disc sand paper, velcro discs can be divided into aluminum oxide velcro disc, silicon carbide velcro disc and zorconia velcro disc. Aluminum oxide velcro disc can be divided into ordinary aluminum oxide velcro disc, calcined aluminum velcro disc and so on. The particle size of disc sand is usually divided into 40# 60# 80# 100# 120# 150# 180# 220# 240# 320# 360# 400# 600# 800# 1000# 1200# 1500# 2000#.
And the application of disc sandpaper is extensive. From the space shuttle to the mobile phones and computers we use, disc sandpaper is used in the production process. Some parts of the space shuttle need to be finely polished with disc sandpaper, and the fuselage needs to be polished with disc sandpaper before spraying paint, so that there will be no paint peeling. Take our common notebook computers for example. If they can have such a mysterious appearance color, they can't lose the fine grinding of disc sand. It is mainly used for polishing, furniture, hardware, electronic accessories. At the same time, the efficiency of disc sandpaper grinding products is very high, which is faster, more convenient and less loss than conventional hand sandpaper grinding; However, the round sand disc also has some shortcomings. At present, with the gradual improvement of the requirements for the surface finish of the ground workpiece, the requirements for the base of the round sand are also higher and higher.

Yugan Jinshi New Material Technology Co., Ltd. is a high alumina ball project of alumina ceramics new material invested by Shandong Enamel Group in Yugan County with a total investment of 80 million yuan. The first phase of the project is 20 million yuan, covering an area of ​​40 mu. After that, it can realize an annual industrial output value of 50 million yuan and directly provide more than 300 jobs for the society. With the official completion and production of Shandong Fuzhou Group's building ceramics new material production project, the cooperation between Shandong Zibo and Jiangxi Yugan has taken a substantial step. This has promoted the cooperation between the two sides to achieve complementary advantages, resource sharing and mutual benefit. effect.
Wang Xingnong, Chairman of Shandong Enamel Group, introduced that the high alumina ball of alumina ceramics is an emerging energy-saving and consumption-reducing industry in the future. It adopts advanced industrial production mode, high degree of automation, stable and reliable product performance, and the current products are already in steel, It is widely used in industrial fields such as building ceramics, petrochemicals, and cement thermal power, and has strong vitality and development potential. High alumina balls are a class of alumina balls that are referred to as high alumina balls due to their high alumina content. High aluminum ball is widely used in different types of ceramics, enamel, glass, chemical industry because of its high strength, high hardness, high wear resistance, excellent specific gravity, small volume, high temperature resistance, corrosion resistance and pollution-free. And so on the factory's thick and hard materials finishing and deep processing. The users of high-aluminum balls are mainly ceramic factories. At present, there are data showing that grinding mud with pebbles (natural stones) + 10% high-aluminum balls (φ35MM) can reduce the grinding time by 15% compared with pebbles alone. Medium aluminum ball + 30% high aluminum ball (φ35MM) grinding mud, compared with only the aluminum ball, can shorten the grinding time by about 30%, simply by saving the electricity cost, about 2 years can be used because of the use of high aluminum The cost of the ball is higher than the "province". In addition to the ceramic industry, quartz, chemical and other industries are also trying to use high-aluminum balls for production. Among them, the quartz factory is mainly used to produce silicon micropowder. It has been proved that, for example, the production of 325 mesh silicon micropowder and the replacement of quartz ball grinding with high aluminum balls can significantly improve the yield and product quality, such as whiteness, uniformity, etc., and due to the loss rate. Without the quartz ball, the manpower and time cost of adding ball stones is saved. At present, the main problem encountered with high-aluminum balls is that high-aluminum balls have high hardness and high brittleness. Dry grinding is easy to cause cracking of the ball stones and pits on the surface of the ball stones, resulting in very high wear. Now it can only be used before leaving the factory. For the method of polishing the ball, pick out the cracked or worn stone to minimize the loss of the customer. Zibo City is one of the important ceramic producing areas in the country, and its advantages in ceramic new materials are very obvious.
In order to better undertake the transfer of ceramic industry in other provinces, Yugan Industrial Park actively builds a ceramic industry cluster in the golden enamel power characteristic base, and its products can radiate to Jiangxi, Fujian, Zhejiang, Anhui and other provinces. In addition, Yugan County has been the home of high-quality ceramic raw materials since ancient times. In addition to the city, Yugan County is an important ceramic material base. There are clay, porcelain stone, clay and other resources in Yugan County. Among them, Yugan County has many kinds of clay and excellent quality. There are many varieties of purple mud, nail mud, white mud and black mud.
On October 19th, the ceremony of the completion and commissioning ceremony of Yugan Jinshi New Material Technology Co., Ltd., a new alumina alumina ceramics production enterprise, was held here in the Golden and Electric Power Characteristic Base of Yugan Industrial Park in Jiangxi Province.
