President of the China Chlorine Dioxide Society and former chief engineer of CNOOC Tianjin Chemical Research & Design Institute Yan Yanqiang introduced that in September 2009, Chengdu Jinxing Lvyuan Company's 6 tons/day chlorine dioxide preparation system was successfully launched. This was the first in China. The large-scale local production device for chlorine dioxide that has achieved import substitution has now been successfully operated for 8 months. The second set of 3 tons/day chlorine dioxide production equipment was successfully put into production on May 27 this year.
At present, Shanda Walter, Chengdu Jinxing Luyuanhe, Guangxi Bosch Branch and Zhongke Kaiwo are all engaged in the development and research of domestic large-scale chlorine dioxide preparation devices. They have applied for more than 10 patents and now have 3 sets of domestic production. The equipment is under construction. There is also a set of equipment that has just been contracted and another set of equipment to be signed. This indicates that the large-scale production of chlorine dioxide in China has been successfully implemented in China.
The first set of domestic chlorine dioxide equipment running for 8 months showed that the main technical and economic indicators have reached the advanced level of foreign devices, generator reaction rate of more than 0.53 mol per liter per hour, the direct cost of chlorine dioxide per ton of about 8,200 yuan. These data indicate that China has not only achieved a breakthrough in the preparation of chlorine dioxide, but also that large domestically produced devices are expected to fully capture the market in the future.
It is understood that 18 sets of chlorine dioxide production facilities constructed in China using foreign technology have been put into production. There are currently 4 sets of equipment under construction. The total chlorine dioxide production capacity has reached 387 tons/day, and the domestic chlorine dioxide equipment manufacturing industry has been abroad for a long time. Monopolized by technology.
In addition, according to Prof. Huang Junli, director of the National Chlorine Dioxide Specialty Committee of the National Chemical Reference Materials Committee, the State promulgated and implemented a new “Pollution and Paper Industry Water Pollutant Emission Standard†in 2008, which will allow the adsorption of organic halogens and two odors As a mandatory standard, the currently used chlorine bleaching process cannot meet the requirements of the new standard. The existing papermaking companies must meet this emission standard. The replacement of chlorine dioxide with chlorine dioxide bleaching method is a top priority.
China 47mm Split Set Stabilizer,Friction Bolt,Split Set Bolt supplier & manufacturer, offer low price, high quality Mining Bolt,Split Set Rock Bolts, etc.
47mm Split set bolt is also called "split set stabilizer". It was successfully developed by American Professor Scott in the early 1970s. It was used as a patented product by Ingersoll Rand for mining support. In the early 1980s, the Beijing Institute of Well Construction conducted exploratory tests on slotted pipe anchors in the laboratory and achieved good results. Later, it was gradually promoted and applied in the coal system.
47mm Split set bolt is a underground mining support product. It has simple installation process and convenient use. It has strong anchoring force and tensile strength in underground mining and shotcrete support. It has Large force, strong expansion force.
47mm Split set bolt has good supporting effect. Bolt support conforms to modern rock mechanics and surrounding rock control theory in terms of support principles, and belongs to active support. After the bolt is installed, the stability of the surrounding rock can be mobilized and utilized, and the bearing capacity of the surrounding rock can be fully utilized, and controls the deformation of the surrounding rock of the roadway effectively.so split set bolt can protect the stability of the surrounding rock of the roadway and improve the maintenance of the roadway.
