From the beginning of the Chinese valve in the 1990s, the number of valve companies in China ranks first in the world, and there are about 6,000 valve companies of various sizes. Among them, 1,806 have annual sales income of more than 20 million yuan. The valve industry is developing very rapidly. Total assets of 194.8 billion yuan, an increase of 2.01%; production of 9,941,100 tons of valves, an increase of 1.32%; realized main business income of 256.6 billion yuan, an increase of -0.47%; total profit of 17.2 billion yuan, an increase of -5.78%; Profit of 6.7%; valve product price index of 98.5%; completed export delivery value of 34.4 billion yuan, an increase of -8.58%. Among them, Jiangsu Province produced 920,000 tons of valve products, with a main income of 54.401 billion yuan, an increase of 4.84% year-on-year, and a total profit of 4.094 billion yuan, a year-on-year increase of -2.55%. The indicators were better than the national average.
Many world-famous valve makers closed their factories in North America, Europe, and Japan to China, India, South Korea, and Central Europe to reduce the cost of valve production and increase sales profits. Following the increase in the development and use of oil and natural gas in China, China's valve shopping malls have increased significantly, which makes most valve manufacturers pay more attention to building factories in China. Therefore, there is an upsurge in the establishment of foreign valve companies in China. Some companies even have multiple factories in China to shorten the delivery distance and delivery time.
Except for some special valves, domestically produced valves can basically meet the needs of the national economy in various fields and infrastructure construction. In particular, in recent years, major breakthroughs have been made in the localization of millions of kilowatts of nuclear power station valves, represented by China Nuclear Su Valve Technology Industrial Co., Ltd., Dalian Dagao Valve Co., Ltd., Jiangsu Shentong Valve Co., Ltd. and Shanghai Valve Factory Co., Ltd. A number of key enterprises have developed important nuclear-level valve products, among which the nuclear-level shut-off valves, check valves, ball valves, butterfly valves and most of the gate valves have been domestically produced. The localization rate of nuclear power valves has increased from 6% 8 years ago to more than 75%. The valve companies represented by Chengdu Chengfeng Valve Group, Wuzhou Valve Group and Shanghai Nile Rice Co., Ltd. developed fully welded pipeline ball valves (PN5-15MPa, DN28′′-48′′) for long-distance natural gas transmission pipelines, and welded below 48′′ Pipeline ball valves can be fully domesticated, and the development of these new products has filled the domestic gap, and some products have reached or are close to the world's leading level.
No matter how the valve industry develops, the quality of products is the foundation of our development, and the core technology of science is the catalyst for our development. We believe that we must adhere to our own principles and find our own way before we can continue to make breakthroughs in our development.
Sodium Lauryl Ether Sulfate
Sodium Lauryl Ether Sulfate (SLES),white or yellowish paste, an anionic Detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste, etc.). SLES is an inexpensive and very effective foaming agent.SLES, sodium lauryl sulfate (SLS), ammonium lauryl sulfate (ALS), and sodium pareth sulfate are surfactants that are used in many cosmetic products for their cleaning and emulsifying properties. They behave similarly to soap. It is derived from palm kernel oil or coconut oil.
Its chemical formula is CH3(CH2)11(OCH2CH2)nOSO3Na. Sometimes the number represented by n is specified in the name, for example laureth-2 sulfate. The product is heterogeneous in the number of ethoxyl groups, where n is the mean. Laureth-3 sulfate is common in commercial products.
SLES is prepared by ethoxylation of dodecyl alcohol, which is produced industrially from palm kernel oil or coconut oil. The resulting ethoxylate is converted to a half ester of sulfuric ACID, which is neutralized by conversion to the sodium salt.[1] The related surfactant sodium lauryl sulfate (also known as sodium dodecyl sulfate or SDS) is produced similarly, but without the ethoxylation step. SLS and ammonium lauryl sulfate (ALS) are commonly used alternatives to SLES in consumer products.
SLES is a kind of anionic surfactant with excellent performance.
It has good cleaning, emulsifying, wetting, densifying and foaming performance,with good solvency, wide compatibility, strong resistance to hard water, high biodegradation, and low irritation to skin and eye.
1.SLES(Sodium Laureth Sulphate) widely used in liquid detergent.; e.g. Shampoo, dishwashing detergent, bubble bath liquid, hand washing etc.
2.If using SLES(Sodium Lauryl Ether Sulfate) to replace LABSA partially, phosphate can be saved or reduced, and general dosage of active matter may be reduced, in washing powder and detergent for heavy dirty.
3.SLES(Sodium Lauryl Ether Sulphate) can be used as lubricant, dyeing agent, cleanser, foaming agent and degreasing agent.; e.g. printing and dyeing industry, petroleum and leather industry.
