Analyses of paint materials by means of modern analytical methods

Induction. After independence a number of changes has been emerged not only in other fields, but also in the customs system. Today our country is extensively developing diplomatic, commodity and collaboration relations between the world countries. The volume of export in many economical areas, including varnish and pain materials is increasing. This state’s firstly that the foreign economical relations (FER) of our country are getting strong; secondly it imposes a deal of responsibility on authority organizations. In this field the state customs system has great importance. The state customs system implements the control and registration of export and import goods [1].

Issues of the subject . Proper determination of international code numbers on CN of FEA proceeding to the chemical structure of all the exporting and importing goods in international economical relations is considered one of the actual issues. Proper definition of a code of paint and varnish goods CN FEA is one of pressing problems. As a result of the analysis of the international codes of the paint and varnish goods by customs examination important data concerning a chemical compound, structures, and also other organoleptic, physical and chemical indicators connected with process of manufacture of the paint and varnish goods are obtained. To properly define a code of the paint and varnish goods affords the chance to warn possible crimes of economic character and to protect economic interests of consumers.

What are CN of FEA and customs cargo declaration . As it is known, each commodity as object of trade is represented in customs bodies together with the Cargo customs declaration, in which along with other columns, without fail there are columns with instructions of the international code article numbers under the Commodity nomenclature of foreign trade activities. The establishment of their cost depends on proper classification of the paint and varnish goods on the basis of objective criteria, and consequently, both well-founded charge and collection of customs payments. Proper classification of the paint and varnish goods is of great importance for increase of objectivity of customs statistics of foreign trade, at the development of a customs policy of the country and the acceptance of concrete measures on its realization in the course of customs registration, customs control of the goods [2,3].

Structure CN FEA: ХХ – group; ХХ ХХ – position; ХХХХ ХХ – subposition (HS); ХХХХХХ ХХ – under subposition (КНЕС); ХХХХХХ ХХ Х -under subposition CIS (Commonwealth of Independent States); ХХХХХХ ХХ Х Х - under subposition (National) [3,4]. National CN of FEA. At present National CN of FTA with 10 – value code number is used in our Customs System. But in this classifier strategic goods has not denoted its determination economically and cannot protect the economical interests of the Republic sufficiently. Vanish-and-pain materials haven’t been considered sufficiently in the scientific sources about the solution of theoretical and practical problems of the classification and certification of goods on the chemical structure [2,4].

Methods and objects: The purpose of this research: the identification of paints produced by “Uz Dong Ju Paint Co” Joint Stock Company possessing strategic importance for our country through up-to-date methods, including 1) IR-spectroscopy. Suggestion new code numbers of goods on the basis of chemical structure. More than 90 % of PM exported within 2012-2015 is appropriated to the share of “Uz Dong Ju Paint CO". Paint materials exported by the company to foreign countries. In 2012-2014 paints with code number 3208109000 on practical CN of FEA produced by “Uz Dong Ju Paint Co” were exported to Russia, Kazakhstan and Kyrgyzstan. We have studied two types of the characteristics of paint materials. 1. QD Primer. 2. BPR Gaz. QD Primer -It is included to the industrial pain group; its composition is alkyd resin; fast drying primer; used as a primer for machine parts and equipment in heavy engineering; also it is used to protect surfaces from corrosion.

BPR Gaz -Automobile paint. Its composition is alkyd resin; mixture of heat and environment stable pigments; used for bumpers of automobiles with transparent varnish; surface enamel padding providing higher and stable outward appearance.

Used instruments - Haz Mit ID 360, perkin Elmer Spectrum Version 10.4.3, Press form Grase by specac, Agilent Tech.7890BGCSystem, ShimadzuGC-2010 Plus.

The discussion of the results

Using infrared spectroscopic analysis to study the structure of two types of paint. Various organic compounds are defined coatings to establish the absorption bands in the IR spectrum. analysis findings are presented in Figure 1.

IR spectrums of QD Primer and BPR gaz paints

When the customs expert studies, in the IR spectrum of the sample coatings need to find a major, the most intense and well-resolved absorption bands. The table below shows the absorption region of paints.

Conclusions. IR–spectroscopy analyses allow the identification of PM; results of IR- spectroscopy analyses are appropriate to Gas-chromatography analyses; the presence of organic substances possessing polymer formation property in the composition of PM; absorption band of these substances in the proper phase has been defined; consequently the role of IR–spectroscopy and Gas-chromatography analyses in the identification of PM at Customs tests and FEA affairs of Customs authorities has been demonstrated practically. In conclusion, it should be noted that the study of the classification of paints on the chemical composition, may clarify some controversial issues HS Uzbekistan. A can also be noted that the investigated paints classified code 3208109000 for Commodity Code of the Republic of Uzbekistan. Development of new product codes makes it possible to protect the economic interests and security of the economy of Uzbekistan in international relations.
