The continuous optimization and upgrading of various sectors of the national economy has promoted the development of a number of emerging industries, such as environmental protection, new energy, and new materials, and has also led to the development of fine chemicals that serve the high-tech sector. While the oil and chemical industry is realizing its own structural adjustment, it is progressing from extensive to refined. It can be foreseen that the development of the fine chemical industry in China will take a new stage. Table 1 shows the major demand for refined and specialty chemicals in China in 2010.
Table 1. Demand for major fine and specialty chemicals in China in 2010, 10,000 tons Industry Demand Industry Demand Coating 400 Adhesive 480~500
Plastic additive 180~200 Water treatment agent 20~25
Paper Chemicals 100~120 Surfactants 150~170
Electronic Chemicals, RMB 260~280
China is the world's largest producer and consumer of adhesives. Its output reached 3.35 million tons in 2003, as shown in Table 2.
With the development of domestic construction, wood processing, packaging, footwear, and other industries, synthetic adhesives will continue to maintain a high growth rate in the future. It is expected that the demand for synthetic adhesives in China will reach 4.8 million to 5 million tons in 2010. Development priorities are: low formaldehyde emission urea-formaldehyde rubber; expanded use of polyurethane adhesives; high-performance construction sealants; electronic industrial adhesives; automotive industry adhesives; environmentally friendly hot melt adhesives and other solvent-free adhesives; The shoes use neoprene and construction 107 glue.

Test Weight Water Bags are also called water weights, load test water bags, lifting water bags, etc. A weighing water bag is mainly used in ship cranes, shipyard cranes, port cranes, offshore platform cranes, gantry cranes, driving cranes, davits, etc., lifting equipment for load detection. It is more efficient, safer and cheaper to detect than traditional solid weights.
â— High-frequency welding is used to make the DOING Load Testing Water Bags, and its outside is wrapped in high-strength fiber slings.
◠Crane Water Bags are made of high-density composite materials (PVC, TPU) with superior sealing and corrosion resistance. It can be used at -30°C to 70°C, and it will not be unable to use normally due to seasonal changes. The material is reinforced with anti-freezing, anti-oxidation, and anti-ultraviolet properties. It is not affected by seawater, chemicals, agents, oil stains, acid and alkali and aquatic organisms.
â— Water Bags for Weight can be folded during transportation, which greatly reduces space. Simple operation, light weight, small size, economical and practical, and long service life.
