Comparison of development at home and abroad and corresponding countermeasures

Although the production and application of water treatment chemicals in China started relatively late, due to the different historical backgrounds of the development of different water treatment fields, it is impossible to generalize the gap between the domestic and foreign countries currently embodied
.

On the whole, since China's water treatment chemicals have been put into production after the 1970s, most of these products are analyzed, imitated, or developed based on foreign patents, with the exception of a few of these products developed by our country, plus China's water treatment The chemical industry has a short development history and limited scientific research funding, so it has the characteristics of weak foundation, relatively backward technology, and low overall level

(1) The output is small, and the scale benefit is not outstanding

Compared with advanced countries, the output of water treatment agents in China is very low
.

The total sales of various water treatment agents in the United States in 1997 was approximately 3.

(2) Incomplete varieties and insufficient serialization

At present, circulating cooling water treatment chemicals such as corrosion inhibitors, scale inhibitors, bactericides and supporting pre-filming agents, cleaning agents and defoamers are basically complete domestically.
They have been able to replace imports in large quantities and can partially Export
.

Through the timely digestion and development of three large-scale technology introductions in different years (13 large fertilizer plants in the 1970s, petrochemical plants in the 1980s, and supporting water treatment technology for Baosteel’s metallurgical plants in the late 1980s), China’s The gap with the advanced level of foreign countries has basically mastered the technology and formula characteristics of some famous foreign water treatment companies such as Nalco, Drew, Betz in the United States, Kurita and Katayama in Japan

(3) There is still a gap in quality

About 80% of China's water treatment chemicals are produced by township and village enterprises
.

After long-term development, a number of excellent companies have emerged that have reached a considerable level in production technology and equipment, production scale and management.

(4) Product technical advantages are not obvious

Compared with water treatment companies in the United States, Western Europe, and Japan, domestic water treatment companies in China lack superior professional chemical varieties and technologies
.

Many Chinese domestic water treatment companies produce more commercial water treatment chemicals than specialty chemicals

(5) The product standardization construction and quality certification system are not yet perfect

The water treatment agent standard is the basis for product quality inspection and product certification, and is an important technical support for promoting scientific and standardized management of the industry, guiding the healthy and orderly development of the water treatment industry, and promoting its efficient, environmentally friendly and safe use
.

At present, China has established a number of product and technical standards related to water treatment products, especially single-component water treatment chemicals.

As the market demand for water treatment chemicals grows year by year, the technical level of enterprises is uneven, and the quality of some water treatment products cannot be guaranteed, especially driven by profits, market competition is chaotic, and the water treatment chemicals market has not yet formed.
National and industry product quality supervision mechanism, product quality lacks supervision
.

On the other hand, the product inspection in the certification rules is based on China’s national standards and industry standards, rather than the internationally accepted NSF/ANSI, ISO and ASTM standards.

Taking a general view of the development differences of water treatment chemicals at home and abroad, according to the new characteristics of China's national economic operation, based on China's actual situation, for the future development and production of water treatment chemicals in China, the following suggestions are made
.

(1) Accelerate industrial mergers and reorganizations to form a professional industrial team

At present, China's water treatment chemicals industry does not have a big gap with foreign countries in terms of product variety, quality and technical level, but there is a big gap in the strength of individual enterprises, promotion efforts, business models and concepts
.

Through industrial mergers and reorganizations, small and scattered industrial teams can be merged, reorganized and strengthened to ensure stable product and service quality; in the process of mergers and reorganizations, professional production and service-oriented water will be formed according to the corporate market and professional advantages.

(2) Connect with the market and continuously innovate product categories

The development of water treatment chemicals should be fully in line with the market, and research topics should start from the market and improve product categories, especially the development of water treatment chemicals and hybrid water treatment chemicals produced using natural raw materials
.

(3) Improve production technology and improve product quality

The main research direction of water treatment chemicals should be to improve the process to reduce consumption, improve quality, and reduce the pollution of its own production; according to the needs of users, research on phosphorus-free or low-phosphorus water treatment formulations; research can be computer-controlled and online measurement Concentration of water treatment chemicals and their application technology; research on water treatment chemicals with special requirements under harsh conditions; research on the use of seawater as a water treatment agent for cooling water; research on natural or semi-natural and biological flocculants; in inorganic flocculants In terms of organic flocculants, the quality of products should be improved; in terms of organic flocculants, a single-series production scale should be achieved, and product quality should be improved (especially by increasing molecular weight, speeding up water solubility and reducing free monomer content); in terms of corrosion inhibitors, adding non-toxic, efficient and applicable For the varieties of different materials and media; in terms of fungicides, reduce user costs and increase varieties that are harmless to humans and fish and have low toxicity
.

(4) Strengthen industry guidance, expand application publicity and promotion

The main problem currently facing water treatment chemicals is that the speed of promotion cannot keep up with the demands of the situation
.
Regardless of the industry or the number of factories, it has not yet been fully promoted.
It is necessary to increase the promotion.
Efforts should be made in the formulation, improvement and implementation of laws and regulations, as well as administrative guidance and intervention
.
With regard to the use of economic levers, such as raising water prices and deadlines for governance, the state has already taken or will take measures, which I believe will have a certain effect
.
In every field and every industry, publicity and promotion should be strengthened vigorously
.

The focus of promotion at this stage should first continue to focus on the cooling water treatment chemicals, and it is best to increase the cooling water concentration ratio from 2 to 2.
5 or more to improve water saving; second, we should vigorously promote the reuse of sewage as cooling water Water treatment technology and chemicals, which have great benefits for saving water and reducing pollution; third, promote non-stop cleaning technology and chemicals to ensure the continuous, efficient and long-term operation of modern factories, which is conducive to energy saving and high production; Fourth, vigorously promote the use of flocculants to accelerate the speed of sewage treatment
.

(5) Improve the construction of relevant standard systems and standardize the development of the industry

The establishment and improvement of relevant standards for the water treatment product industry should fully consider the current development of the domestic market and the industry, be in line with international standards, guide and standardize the healthy development of the water treatment chemicals industry, and improve the international competitiveness of the industry
