  • Detail

Zhejiang 3 rubber and plastic top project has won the support of national innovation funds. Recently, the national science and Technology Innovation Fund announced the announcement of the second batch of projects approved by the technology innovation fund for scientific and technological small and medium-sized enterprises in 2011. Three projects in the rubber and plastic industry of Zhejiang Province have received free support from the national technological innovation fund of 3million yuan

it is understood that these three projects are the high wear-resistant in-situ chemical grafting polar elastomer and its special V-belt for automobiles of Zhejiang Zijingang tape Co., Ltd., which have received 1.4 million yuan of financial support; The laser surface strengthening and three-dimensional remanufacturing of plastic machine screws by Zhejiang Dongbin rubber machine screw Co., Ltd. was supported by RMB 800000; Hangzhou zhongbing environmental protection Co., Ltd.'s technology and equipment for the prevention and control of dry oxidation of rubber odor waste gas have won a financial support of 800000 yuan

high wear-resistant in-situ chemical grafting polar elastomer is an industry university research cooperation project jointly developed by Zhejiang Zijingang tape Co., Ltd. and Qingdao University of science and technology. In this project, in-situ chemical blends of random vinyl polybutadiene, syndiotactic polybutadiene blends or random styrene butadiene copolymers with high main chain saturation, containing vinyl side groups and good comprehensive properties are prepared by chemical blending method. With this as the basic material, through the further polar monomer modification of the double bond contained in the molecular chain, good oil resistance and temperature resistance of wire rod (Shagang Yongxing, Yaxin, etc.) deep processing (Xieli cold rolling, Longteng special steel) construction reinforcement (Yuanda Kejian, construction site) are obtained. The material has the characteristics of good oil resistance, wear resistance, long service life and low cost. Its performance is superior to that of imported neoprene and close to that of imported hydrogenated nitrile rubber. It can replace imported neoprene and hydrogenated nitrile rubber, but its price is lower than that of imported neoprene (the new material is about 35000 yuan/ton, and the imported neoprene is about 56000 yuan/ton). At present, the project has built a pilot production line with an annual output of 300 tons, which has entered into small batch production. The elastomer parts of the transmission belt of high-performance vehicles prepared by the pilot products were appraised by the Department of science and technology of Zhejiang Province in September 2002, and their technology reached the international advanced level. They were recognized as high-tech products of Zhejiang Province, and won the advantage product award in the China International High Tech fair

the project of laser surface strengthening and three-dimensional remanufacturing technology for plastic machine screw barrel undertaken by Zhejiang Dongbin rubber machine screw Co., Ltd. adopts the joint research method of industry, University and research, and uses the laser surface strengthening and three-dimensional remanufacturing technology to change the currently commonly used double 2010 local enterprise R & D funds to an average of only 1.77% of the enterprise's sales revenue. The surfacing surface treatment process for metal screw barrel has been changed into a metallurgical combination under the condition of laser, It also realizes the quick and efficient repair of the damaged screw barrel, greatly improves the service life and extrusion performance of the screw barrel, reduces the production cost, and has a certain positive significance for improving the technical level of the plastic machine industry

Hangzhou zhongbing environmental protection Co., Ltd. is a high-tech enterprise specializing in environmental pollution control. Many people of the company do not know the self-developed dry oxidation prevention technology and equipment for rubber odor exhaust gas, including bag type dust collector, ozone generator, oxidation reaction tank and gas adsorption oxidation device. The bottom of the bag type dust collector is provided with a rubber mixing waste gas inlet. The bag type dust collector is connected to the air inlet of the oxidation reaction tank through a fan. The ozone generator is connected to the air inlet of the oxidation reaction tank. The air outlet of the oxidation reaction tank is connected to the gas adsorption oxidation device through a pipe. The gas adsorption oxidation device is provided with a purified gas discharge outlet. The device mainly solves the problems of low purification efficiency, high cost, insufficient reaction between rubber waste gas and ozone, and secondary pollution in waste gas treatment. The dry-type oxidation equipment of rubber odor waste gas developed by the enterprise has been successively installed in the internal mixing center of Hangzhou Zhongce and Hangzhou Yokohama, and the collection and purification effect of rubber mixing waste gas is good
