A, 2004 years ago in the domestic market situation of electroplating intermediates industry

1 in imports, domestic electroplating intermediates industry market monopoly

Electroplating intermediates, it is a kind of fine chemicals for compound with electroplating additive. For different application requirements of electroplating additives, electroplating intermediates used in different. Some electroplating intermediates purposes are very special, except for electroplating additive compound with almost no other purposes; And some electroplating intermediates not only can be used to compound with electroplating additives, and other widely used, many domestic manufacturers. Here, we call the former special electroplating intermediates, the latter for generalized electroplating intermediates. Here, we mainly to special electroplating intermediates market is analyzed and discussed.

Electroplating intermediates main products are made from galvanized intermediates, intermediates and copper plating nickel plating intermediates of three series products. Galvanized intermediates market development earlier, relatively simple production process and technology. And galvanized intermediates market by the intermediates of domestic enterprises, in this will not be too much to discuss. But, in nickel plating and copper plating on the main intermediate products, almost monopolized the whole market for imported products. In the electroplating industry before 2004, electroplating intermediates and additives, electroplating are imported products occupying most of the market share.

The nickel plating intermediates in the domestic sales of about 200 million yuan, and PPS is main products, intermediates in nickel products plays an absolutely important position. PPS chemical called propane sulfonic acid pyridine salt om, its products are high purity, at high current density area excellent leveling performance. Its sale price is higher compared to the same; In compound with adding of electroplating brightener is high, the output value estimation can achieve about 30% of the total nickel intermediates series, the sales of a product can reach 60 million yuan, visible PPS production economies of scale in the important position of the nickel plating intermediates series products.

Before 2004, domestic imports of PPS suppliers mainly in Germany, in terms of the international market, is dominated by a few companies. Because there is no too much problem such as the production technology and equipment, the company produces the product, the products on the market caused by production difficulty is big, less competitive. Scale of domestic production of PPS supplier there is only a little one or two companies, as there were not enough product quantity and quality guarantee, the customer not much choice. In terms of domestic market at that time, PPS by imports almost monopolized the market share of 90%.

In the copper plating intermediates, the main products are SPS. In the acid copper brightener, on the market demand for this product is very big, good application effect. In the domestic market, acid copper brightener products are mainly in the form of finished product imports, monopoly not only most of the domestic market, and the price is expensive. Domestic acid copper brightener, import SPS customers generally preferable to add, its content can reach 80-90%, less impurity, but due to the product price is higher, to the customer competition. And some domestic manufacturers, technology, and many other factors, produce the SPS content in 50-60%, the purity is not enough, more impurities, limits the application in the domestic market.

2, domestic electroplating intermediates enterprise production process, quality and compatibility of obvious lag behind

For domestic electroplating processing industry, and strive to to guarantee the quality of products at the same time, hope that the domestic enterprises to provide high-quality additives; As a domestic electroplating additive producers also hope to be able to find high quality electroplating intermediates, reduce production cost, meet the market demand.

Before 2004, according to the electroplating intermediates market research and analysis, in the electroplating intermediates supplier in China can be divided into two camps: one is the electroplating intermediates of imported products supplier, another is the domestic production supplier electroplating intermediates. In the intermediate market at that time most of the high end customers in the use of imported intermediates, such quantity accounts for the vast majority of customers, and supplier of imported products in the industry brand strength, popularity is bigger, strength is abundant. In the intermediate demand for low-end customers, most products using local suppliers.

Due to domestic intermediates production enterprise r&d strength is insufficient at that time, a lot of electroplating intermediates production or used in the 80 s and 90 s technology, led directly to the poor quality of products, there are some more intermediate due to reasons such as raw materials, process, equipment, the domestic enterprise can't production, also need to form a complete set with imported products. Quality of domestic products and imported products have obvious difference, the product not update in time, the product is not complete, poor compatibility.

Second, the domestic electroplating intermediates industry in recent years the development of the status quo

Electroplating intermediates 1 and domestic enterprises are gradually breaking monopoly, products occupy industry commanding heights

Domestic electroplating intermediates manufacturers to develop, with the development of metal surface treatment. In order to satisfy the demand of the market, production, the development of competitive products, with the foreign similar products of domestic and international market competition, the development of national industries, and set up the national brand. If you can produce similar products, the products and imported products belong to the same class, and in domestic production, the most advantage on the price. Not only can the high side to win the majority of the users, the market opened at the same time, also can set up your company's brand.

Nickel electroplating intermediates is made up of more than 30 different structure and function of the chemical composition of a group of products. Every product has its special purpose, only the multiple intermediates with different performance together, to compound with the different function of electroplating additives.

As an associated with other intermediate height, height matching products, PPS no matter from the perspective of enterprise itself or from the perspective of market customers matching purchase, other intermediates are inseparable. Due to imports of PPS products are expensive, the domestic production enterprises intermediates for other intermediates series product sales is affected by the serious. While all other major intermediates have localization, localization of PPS is the only choice and its market demands. PPS import product is priced at 160 yuan per kg and localization can enable customers to reduce procurement costs, improve product competitiveness, but also can expand the domestic market share intermediates, to break the monopoly, to seize the commanding heights of the intermediates industry!

Because PPS production line of devices and equipment requirement is high, need one-time investment amount is larger. Moreover, the product life cycle on the market more and more short, the timing of market entry is very important. Before 2004, PPS bigger market, competition is relatively small, it is good time to aggressively market promotion, PPS production line planning an eyebrow. In September 2004, in hubei YingCheng, 200 tons/year PPS production line put into operation, one-time successful commissioning. Compared with imported products, product performance is close to, the sales price of 120 yuan per kg, 30% cheaper than similar imported products, comprehensive cost-effective products, highly competitive advantage.

PPS after localization, breaking the monopoly situation of imported products in China, the market share of the product was increased from 10% to 30%. PPS localization for the international market also provides more a way of choice, for the domestic enterprise itself into the international market.

In April 2008, SPS and industrialize production in wuhan. Wuhan city technology bureau presided by the assessments of acidic copper plating additive SPS synthesis technology. The experts listened to the team's work report, technical reports, reviewed the project team to provide the related information, through expert appraisal committee discuss carefully, form the following opinions:

To sum up, prove the product process both technical level and product quality standards, both in mature stage. With the basis of the scale production of mature and reliable technical support.

The domestic production of SPS, filled the domestic electroplating intermediates industry in blank of main products, copper plating intermediates greatly improved the product in the competitiveness of the domestic and foreign markets, to the development of domestic acid copper brightener market laid a solid foundation. The market price of imported SPS in more than 500 yuan per kilogram, price of homebred SPS below 300 yuan per kilogram. Invention and use of this new process, not only save resources, reduce the energy consumption and improve the quality of the products at the same time; Due to significantly reduce the product cost, to a certain extent also promoted the development of the acid copper electroplating intermediates industry in China, make China's copper plating intermediates acid copper plating and electroplating industry has a certain status in the world.

2, large-scale production of high quality electroplating intermediates, to improve the quality of our products

PPS and mass production of SPS have not only brought considerable benefit, the more valuable is that it is successful to electroplating intermediates industry provides a long-term sustainable development direction. It is based on surface treatment industry, vigorously develop large-scale high-quality fine chemical products.

In research on the construction of infrastructure, the domestic enterprises inject money imported from abroad a number of intermediates including high performance liquid chromatograph, gas chromatograph, uv-vis spectrophotometer, electrochemical analyzer and other advanced equipment, to ensure that for developers to provide accurate, fast test data. PPS and SPS for our country independent research and development of two kinds of new products, filled in the electroplating intermediates in our country main products in the blank. For the domestic electroplating intermediates laid a solid foundation of technical innovation. Then the domestic intermediate enterprise continuous improvement on the product:

(1), allyl sulfonate (ALS). Nickel plating auxiliary brightener, can effectively improve the ability of metal distribution and range of motion. Product appearance is colorless to light yellow transparent liquid, is nickel plating and additive primary brightener. ALS are important in the role of the brightener, determines the brightener light and fill up the basis of performance.

After many experiments, changing the catalyst. After improvement process, the yield of product, by-products. Products can be placed for a long time at room temperature and do not change color, content, pH stability within the prescribed scope.

2, propiolic sulfonic acid sodium (PS). Low area of nickel plating brightener, leveling agent, can effectively improve the low area light and bridge, obvious effect, brittle small. Product appearance is colorless to light yellow transparent liquid, pH value of 4 to 6, the content of 20% or higher.

New technology of production strictly control the content of raw material. Control the content of the material being refined, a stable and high content of the above, ensure the product of the by-products in a very low level. The improved PS product performance is stable.

(3), c oxygen radicals propiolic alcohol ether (PAP). Nickel plating brightener, leveling agent, can quickly out of the light, the effect of the coating can play a raven. Product appearance is light yellow to yellow transparent liquid. Quality detection using gas chromatography, the secondary ingredients for propiolic alcohol and double c oxygen radicals propiolic alcohol ether. Improved process before using general product synthesis process in the industry, because of the low conversion rate, low content of products, only about 50%. The same condition test import product content is about 76%.

New production process using the high efficient catalyst, significantly higher catalytic efficiency, yield increased significantly, the secondary ingredients relatively reduced a lot. Product content can be as high as 85% above, it is more than foreign level, and the product performance is stable.

Three, to explore the developing direction of domestic electroplating intermediates industry

1, electroplating intermediates product innovation to meet industry demand for higher quality

DEP, chemical name of N, N - diethyl propiolic amine, nickel plating brightener, leveling agent. Improved process before DEP existence appearance is not stable, and the impurity is more, the highest levels of only 95%. New technology of domestic enterprises producing high-effective catalyst, the yield increased significantly, content can be as high as 98% above, and stable product appearance, less impurity. The DEP synthesis process had applied for national patent, patent number: 200810197269.8. New technology of DEP has reached the international quality, the present market share has exceeded imports of similar products.

New technology DEP, through gas chromatography detection (GC), product quality has improved significantly. Below is DEP gas chromatography (GC) map, in the same conditions. Products are: the original sample and the improved samples.

2, conquer electroplating intermediates technical barriers, leading the industry development direction

In terms of the current electroplating intermediates market, nickel and zinc plating intermediates market has by domestic electroplating intermediates enterprises occupy a larger market share, domestic electroplating intermediates no matter from the quality of the product, production process and are close to the import of sex of electroplating intermediates, and the extensive customers electroplating additive also accepted the domestically produced intermediate products and services. But in acid copper plating intermediates series products, domestic intermediates overall is still in the backward position.

Investigate its reason, and in intermediates acid copper core product - acid copper plating used dye unable to realize large-scale production; The quality of the products is difficult to comparable with imported products. As the dye chemical synthesis process, is a series of chemical reactions in a row, must have a fine chemical enterprise specialized in research and development and production experience to synthesis. Every step of the synthesis conditions and process are complex, difficult to control. The whole reaction steps, each unit reaction determines the next cell reaction and the result of the final product quality and yield. Because the production of technical barriers, there are no electroplating intermediates in domestic enterprises to research and development process to produce acid copper with dye. This led directly to the foreign enterprise not only controls the acid copper plating with dye market, high-end acid copper brightener also monopolized the domestic market.

After the successful localization of SPS, the domestic enterprises with the demand of the market as the guidance, the research for tissue using innovative synthesis process, in June 2009, high purity solid acid copper plating with dye also implements localization. The product for phenazine kind of dye, for dark blue dye and purple dye. This series of products to fill the gaps in acid copper localization with dyes, greatly improve the acid copper intermediates. Outstanding, break through the foreign enterprises with technical barriers, for domestic high-end acid copper brightener provided the impetus the development of the market.

Four, domestic electroplating intermediates industry outlook for the future

Reviewed the development of nearly 10 years of electroplating intermediates industry, domestic intermediates production enterprises have made great progress. They constantly through product innovation, make the enterprise got rapid growth. On some key electroplating intermediates products, the realization of the localization, the quality has reached the international level. In 2004, domestic companies in the nickel plating intermediates the market share of about 30% of the industry, through five years of efforts, now the market share of up to about 60%, the market's annual sales is about 120 million yuan. By creating brand, some enterprises have made continuous development, in the domestic electroplating intermediates industry has achieved good reputation, has a strong brand appeal. As these enterprises bigger and stronger, electroplating intermediates market share will be expanded, and in the broader international market to obtain the harvest.

To explore the development direction of domestic electroplating intermediates industry, electroplating intermediates production enterprises must begin from the following three points, and to push the domestic electroplating intermediates industry more sustainable development direction: first, the production enterprise must adhere to product innovation, new technology, new products go hand in hand; Second, the management of the production enterprises to be more perfect, scientific and improve efficiency; Third, production enterprises to expand exports, improve electroplating intermediates domestic enterprises on the international brand appeal.
