With the continuous improvement of technology and continuous innovation of brown corundum , the scope of application of corundum products has gradually expanded. In addition to the traditional refractories, abrasives, ceramics and other industries, the application in the beauty and chemical industries has also gradually increased, plus the production of corundum Bauxite resources have been decreasing year by year, and the limited production capacity has made the already strong corundum prices continue to rise to a high level.
In addition to the ore factor, the energy issue is also critical. OPEC prices of international crude oil fell slightly on Tuesday, but Asian fuel oil prices rebounded on Wednesday. Now that the weather is getting warmer, people are travelling more and more, and hibernation in tourism and transportation has passed, and it may be difficult for oil prices to return for a period of time. The production and transportation costs of brown corundum companies are still increasing.
This year is the first year since the new labor law was enacted. Coupled with the continuous rise in prices in the recent period of time, the employment costs of enterprises have increased the expenses of enterprises. The ever-decreasing profits of manufacturing companies also make it necessary for companies to break through by rising prices.
In terms of exports, the continuous appreciation of the renminbi over the past two years has also brought considerable pressure on production enterprises. It is predicted that by the end of this year, the appreciation of the renminbi will reach about 6.9 yuan per dollar, and the export of brown corundum will gradually reduce corporate profits because of foreign exchange.
The declining ore resources and the continuous increase in production and transportation costs make it reasonable for brown corundum prices to continue to rise.
1. Brown corundum is generally composed of a complete suction dry blasting machine generally composed of six systems, namely the structural system, the medium power system, the piping system, the dust removal system, the control system and the auxiliary system.
2. Working principle
Brown corundum is driven by compressed air, and the negative pressure formed in the spray gun by the high-speed movement of the airflow. The abrasive is sucked into the spray gun through the sand conveying pipe and ejected through the nozzle, and is sprayed onto the processed surface to achieve the desired processing purpose. In the suction-type dry blasting machine, compressed air is both the supply power and the acceleration power of the jet.
