On August 10, it was learned from soft control Dalian Tiansheng General Machinery Co., Ltd. that China's first butyl rubber post-treatment equipment with independent intellectual property rights has successfully achieved continuous and stable operation for 110 hours. According to reports, compared with foreign products, this set of equipment can not only better protect the physical properties of rubber and reduce production energy consumption, but also the price is only one third of the imported equipment, and can save a lot of engineering investment

Qi Runtong, Secretary General of China Synthetic Rubber Industry Association, pointed out that the equipment filled the domestic gap, and the rubber treated by it reached various indicators of national standards in terms of output and quality

it is reported that this set of equipment includes nearly 30 sets/sets of equipment of gbt242 ⑴ 997 metal tube flaring test method. It adopts the "two machine" (extrusion dehydrator, expansion dryer) technology, which has obvious advantages over foreign equipment using the "three machine" technology (extrusion dehydrator, pre expansion dryer, twin-screw dryer). First of all, the "three machines" technical equipment has a large number of rubber shearing times, and the high-temperature heat transfer mode adopted has a great damage to the rubber polymer, which is not conducive to the protection of the physical properties of rubber raw materials; The equipment adopts the head reflux heating technology, which makes the friction in the rubber heat up, and can better protect the physical properties of the rubber. At the same time, the power and energy consumption of the equipment are also lower than those of foreign products

the price of this set of equipment is only one third of that of imported products. In addition, the production line of "two machine" technology has one floor less than that of "three machine" technology in plant layout, which also saves a lot of investment in civil engineering

the relevant person in charge of the company said that this set of equipment integrates a number of innovations. In the process of research and development, they have obtained eight innovative patented technologies, including the rapid opening and closing template mechanism, the free water separation device of the extruder, the straight cylinder of the extruder with supplementary dehydration, the self-cleaning ultra-fine dehydration screen, the clamping mechanism of 12 cutters, the hot box for supplementary drying, the suspended cutter mechanism, and the zero accumulation slow flushing groove

it is understood that for a long time, the domestic rate of synthetic rubber post-treatment equipment in China is very low, and almost all the post-treatment equipment of butyl rubber, the fourth largest rubber in the world, depends on imports. Butyl rubber has excellent air tightness and water tightness, and is widely used in tire inner tubes and medical rubber. However, because of this, the reaction of butyl rubber to heat has seriously affected the slow price trend of MEG in this region and even all Asia, and moisture is difficult to vaporize and volatilize. Therefore, dehydration and drying, two post-treatment technologies and equipment, are recognized as difficult problems in the industry, and have been monopolized by foreign companies. High prices, long supply cycles and sluggish services are beyond the endurance of ordinary enterprises

Dalian Tiansheng finally developed butyl rubber post-treatment technology and equipment with independent intellectual property rights in combination with rubber production technology and the support and cooperation of Zhejiang Xinhui company. This marks that the post-treatment equipment of synthetic rubber with non composite membrane in China has moved from "made in China" which was originally simply imitated to "made in China" which combines theory, process, technology and machining
