At present, our country by the centralized management of the paints and pigments for Standardization Technical Committee of pigments standard a total of 62, 45 of which national standards, industry standard 17. The content includes standard for the basic, pigment products and test method for the field of pigment. These standards constitute the national and industry standards of the existing paint system, in guiding production, improve product quality, promote trade and promote the application and development of products and other aspects have played an important role.
At present, China's paint standards with international standards of the adoption rate is about 59%, higher levels of adopting most of the standard test method. The conversion rate of the international standard is 46%, which is not suitable for our country's standard.
China's existing pigment standards play an important role in the development of China's pigment industry and related fields, which is mainly reflected in: it is the technical basis for the production and development of enterprises, and the government regulate the market; promote the adjustment of product structure, promote the development and application of new technology and new products.
Pigment GB and international standards actively docking
China's national and industry standard system in addition to include testing methods and product standards, but also includes the classification of the pigment field, such as the basis of the standard, such as sampling, in which most of the method of testing method of the corresponding international standards.
China's pigment industry in the field of national and industry standards in addition to the basic standard of the number of total of 57, of which 34 Standard Test method, product standards 23, mainly by the inorganic pigment and organic pigment product standards. The international standard number is 80, of which the standard of test method 42 (which has 9 test method standard is transformed into the paint standard system, most of which have been transformed into national standard), product standard 38, by the inorganic pigment and physical pigment standard constitution, in which the body pigment standard has 22.
Organic pigment product adoption is still blank. Although inorganic pigment can be used, but because of the main characteristics of the two indicators - color and coloring power, in international standards are "agreed", therefore, the previously developed standards are usually based on domestic habits according to the actual level of selection. This practice is with the international usual practice has certain difference, pigment standards enacted in recent years has been gradually reverse the practice and keep in line with international standards, in 2003 as the completion of the approval of titanium dioxide (titanium dioxide pigment) standard in 2004, complete approval of chrome green standards.
The revision of the standard system of our country is in the process of
Organizing a national standard and industry standard formulation, revision is standardization work is one of the most important content, in 2002 so far, China completed the five national standard and standard formulation, revision: GB GB/T5211.1-1985 the pigment determination of matter soluble in water -- cold extraction method ", GB GB / T5211.2-1985 the pigment determination of matter soluble in water -- hot extraction method", GB GB1706-1993 the titanium dioxide pigment ", marking the mica pearlescent pigment," GB "chrome oxide green pigments." 2004 is the national standard of cleaning up and rectification, the National Committee of the national standard of the 7 experts invited to be familiar with the field of paint, the use of a focus on the evaluation of the way to clean up the standard. The 45 national standards for pigment are evaluated, there are 2 mandatory standards, 43 recommended standards, the evaluation conclusion is: to continue to effectively 29, 9 amendments, the integration of amendments 6, 1.
The main problems existing in the standardization of the pigment industry in china:
1, the standard age is too long. In the field of pigment, about 10 years of age, the majority of the standard is 80 years, the standard of the standard, the age of 5 years, about 90%, the standard age is too long.
2, substantive participation in international standardization work difficult. On the basis of funds, the exchange between the Secretariat and the ISO/TC35/SC2 is mainly rely on the network, letters. At present, the international standard of pigment is still in passive tracking, collection and transformation of the international standard, it can not be synchronized with the international standards, substantive participation in international standardization activities, there are many difficulties.
3, the enterprise to the substantive participation in the international standard drafting is still lack of understanding. After China's entry into WTO, some developed countries have the tendency to use the standard to set up non-tariff trade barriers.
The enterprises to actively participate in the international adoption of synchronization, the importance of standard drafting is not understanding.
Pigment standard "five eleven" planning
According to WTO/TBT regulations, the United States, Germany, Britain, Japan and other industrial countries are committed to adopt international standards in international trade as a technical basis for market access. At present, China's paint standards with international standards of the rate of adoption of international standards and the conversion rate while than to high some (such as standard in the field of coating) in some areas, but there is still a big gap compared with developed countries, so pigments for standardization work to continue to adhere to the international standards, improve the degree of adoption of international standards, and to improve the pigment product competitiveness in the international market to promote the export products and achieved good economic benefits; second, we must valued substantive in the revision of the international standard, through unremitting hard work, turn passive to active, to improve the ability of enterprises to actively respond to market demand at home and abroad.
According to the results of the 2004 national standards for cleaning up the "five eleven" period, China's pigment field to be revised and integrated revision of the standard has 13, of which 11 standard, product standard 2, according to the industry needs to be developed by the standard has 1, the transformation of dispersion assessment method and dispersion method series international standard 9.
The dispersion properties of pigment are
