Industry) and coal, oil, natural gas, air, water, etc. In addition, many by-products and wastes of industrial sectors are also raw materials for inorganic chemicals. For example: coke oven gas in the coking production process in the iron and steel industry. The ammonia contained in it can be recycled with sulfuric acid to make ammonium sulfate, chalcopyrite, and galena. Sulfur dioxide in the smelting waste gas of ore and sphalerite can be used to produce sulfuric acid and so on. How long is the shelf life of chemical raw materials? No chemical raw materials. The global dyestuffs are rising simultaneously, which will have a greater impact on the later dye market and even the entire printing and dyeing industry. At present, dye production enterprises and printing and dyeing factories are facing huge environmental pressure, production capacity cannot be fully released, production costs continue to rise, and prices are raised again and again. In May or even in the second half of the year, the effect of environmental protection + the contradiction between supply and demand may help the printing and dyeing industry continue to operate at a high level. Waste chemical dyes recycling service, rest assured and reliable recycling downstream textile, grey cloth, printing and dyeing factories how to deal with the background of rising oil prices, labor shortage, environmental protection and safety supervision, etc., in the downstream of the polyester industry chain without the right to speak and bargaining power textiles , Grey cloth, printing and dyeing and other manufacturers have been struggling with the sound of "rising". Many factory leaders said that compared with last year, production and operation costs have risen by more than 10%, and profits are getting less and less. ↙ハけ〓△□

After biological treatment, significant changes have taken place in terms of volume, shape, composition, etc., which is convenient for transportation, storage, utilization and disposal. Biological treatment methods include aerobic treatment, anaerobic treatment, and facultative anaerobic treatment. Compared with chemical treatment methods, biological treatment is generally cheaper in terms of economy and its application is quite common, but the treatment process takes a long time and the treatment efficiency is sometimes not stable enough. For the chemical industry with a backlog. Chemical recycling is a supplementary program. Chemical raw material recycling is recognized. When the physical recycling is excessively degraded, there are too many impurities, and the mixing is serious, which makes it unsuitable to use the physical recycling method, chemical recycling is a supplementary program to the physical recycling. In addition, the production of fuel can also bring huge returns. The person in charge of chemical raw material recycling said: "The concept of chemical recycling should not divert people’s attention from the real solution to plastic pollution. The way to really solve plastic pollution is to replace disposable plastic products, simplify new plastic products, and remove toxicity. Design New business models to effectively use plastics."
And environmental pollution is of great significance. Automobile three-way catalysts are mainly used to purify automobile exhaust. With the improvement of automobile exhaust emission standards in various countries, the application of three-way catalysts in automobiles has been very common. It is mainly composed of porous ceramic materials and catalysts. The catalyst The composition is platinum group metals such as platinum palladium and rhodium, high temperature. Yangzhou Recycling Sebacic Acid Recycling Resin made the following recommendations: 1. Define chemical recycling, and any situation that hinders the production of new plastics will be excluded. dmvlnq

At present, only manufacturers and related inspection agencies can distinguish the authenticity of engine oil. Some of the fake engine oil on the market is shoddy and some are directly converted from waste engine oil. It is more difficult to distinguish the true nature of lubricating oil. The method is to smell the smell and look at the oil. How to calculate the price of recycled ink? Regarding the smell of recycled chemical materials, normal gasoline smells very mild. If there is a pungent smell, it may be recycled oil. In appearance, the real engine oil is transparent, free of impurities, no suspended matter, and no sediment. The opposite is engine oil. , Inject into the mold while mixing instantaneously, and react quickly in the mold cavity, the molecular weight of the material increases rapidly, and a new polymer containing new characteristic group structure is generated at an extremely fast speed. 11. Foaming index: the number of parts equivalent to water used in 100 parts of polyether is defined as the foaming index (IF). 12. Foaming reaction: generally refers to a reaction in which water reacts with iso-ester to generate substituted urea and release CO2. 13. Condensation. Zhuang Di
