The monopoly of foreign companies in the field of high-grade dispersants for pesticides has come to an end. On May 27th, the industrialization project for the special auxiliaries for pesticide carboxylate pesticides undertaken by Sinochem Chemical Science and Technology Research Institute passed the expert appraisal organized by China National Chemical Corporation. The GY-D01~D04 series of products developed by this project have formed a production capacity of 500 tons/year and have been promoted for use in a number of environmentally friendly pesticide products. The successful development of polymer carboxylates means that the development of special pesticides for pesticides in China is beginning to accelerate. At present, the results of this project have applied for two national invention patents. Now it has developed and produced a series of carboxylic acid salt dispersants, two liquid products and two solid products. In addition to the establishment of a 500-ton/year carboxylate dispersant production facility, the researchers also conducted research on the application of new special additives in pesticide environmental protection formulations, and developed a number of environmentally friendly pesticide product formulations and special additives. Compared with similar foreign products, the newly developed carboxylic acid salt dispersant has obvious cost-effectiveness, its performance is comparable to that of foreign products, and its selling price is 30% lower than similar foreign products. At present, the price of imported solid carboxylate dispersants exceeds 85,000 yuan/ton, and the newly-developed carboxylate salt price is only 60,000 yuan/ton, which can reduce the production costs of related domestic pesticides. According to Dr. Zhang Zongqi of the China Chemical Industry Research Institute, researchers have solved a number of problems in the R&D process. They have achieved the goal of accurately controlling the molecular weight range of the product through the selection of initiators and dosages; Hydrophobic polymer surface treatment of carboxylic acid salt dispersant effectively solves the problem of moisture absorption of the product; using cis-type spray drying technology, the combination of tube dryer and solid material conveying equipment not only reduces the drying temperature, Solve the problem of product sintering, but also improve the drying efficiency. Dr. Zhang Zongyi introduced that the economic benefits of the project are very significant. At present, the new dispersant GY-D series products have sold more than 70 tons, and they also provide technical services for more than 10 domestic processing companies, and realize sales and technical service income of more than 12 million yuan. After the project is expected to reach production capacity, it can increase sales revenue by 50 million yuan each year. Bitumen Heating Storage Equipment Asphalt heating storage equipment is an important road construction equipment, mainly used to heat and store asphalt in order to carry out road construction and maintenance when needed. The equipment has the characteristics of high efficiency, safety and environmental protection, and can provide stable asphalt supply for road construction.

Asphalt heating storage equipment is mainly composed of heating device, storage tank and control system. The heating unit uses oil or gas burners to transfer heat to the asphalt to heat it to the proper temperature. Storage tanks are large containers used to store heated asphalt, generally made of high-temperature resistant materials. The control system is responsible for monitoring the operating status of the equipment and the temperature of the asphalt to ensure the safe and stable operation of the equipment.
The heating principle of asphalt heating storage equipment is to transfer heat to asphalt through thermal conduction, so that it is heated. Heating devices are generally divided into direct heating and indirect heating in two ways. Direct heating is the use of the burner directly into the storage tank, hot air through the contact of hot air with the asphalt to heat it. Indirect heating is the use of heat exchangers to heat the asphalt in the storage tank without direct contact with the air. The two heating methods have advantages and disadvantages, and need to be selected according to the actual situation.
Asphalt heating storage equipment heating speed, can quickly heat asphalt to the use of temperature, improve production efficiency. At the same time, the equipment also has environmental protection characteristics, reducing exhaust gas and smoke emissions, reducing the impact on the environment. In addition, the operation of asphalt heating storage equipment is simple and easy to maintain, which can meet the needs of various road construction and maintenance projects.
In short, asphalt heating storage equipment is an important road construction equipment, with high efficiency, safety, environmental protection and other characteristics. It can provide a stable supply of asphalt for road construction, improve construction efficiency, reduce the impact on the environment and waste of resources. The equipment has a wide application prospect in the field of road construction.
