Chief engineer OF [F].[I]. Of [afanasev]
Deputy of [gl].[inzhenera] on KS and repair Of [a].[G].[Yusupov]
Master mechanic [S].[E].[Podtsepnyak]
Deputy of [gl].[mekhanika] [V].[V]. Of [vorfolomeev]
Deputy of [gl].[mekhanika] [I].[A]. Of [gavrilin]
General foreman of №34 [M].[YU]. Of [brailyan]
Chief engineer OF [A].[V]. Of [kirzhakov]

Agenda: the prospect of applying the anticorrosive priming enamels “Of [unipol]” of the production privately held company [NPO] “Of [korrzashchita]” on joint stock company “caustic”

They came out: the general foreman Of [brailyan] [M].[YU].

Joint stock company “caustic” as far as the agreement about the collaboration of №108/32 from 8.02.2006 s privately held company “[NPO] Of [korrzashchita]” ([g].[Moskva]) was obtained for conducting the experimental-industrial tests priming enamel [UNIPOL] of stamps [o], of B and explosive a quantity of 2 kgf (commodity additional №89 t of 16.02.2006[g].)

Priming enamel was transmitted for checking the technological effectiveness of putting, time of drying and fulfilling the complex of tests before the aggressive media beside the laboratory of the shop of №34.

Models after sand blasting were covered for the sake of priming enamel beside 5 layers by brush with the observance of the requirements of the instructions beyond the putting, developed as far as privately held company “[NPO] Of [korrzashchita]”.

with the application of coating beyond the models is revealed [sledushchee]:

• enamel is brought without the inflows;
• enamel is brought well down the moist surface;
• models after coloring have the short time of drying, which corresponds to declared technical specifications;
• the color of coating corresponds to that declared;
• surface after coloring flat, does not have cracks, scalings, inflations.

Models in accordance with the recommendations of producer were left around the complete set of physicomechanical properties at room temperature with the purpose of further tests before the aggressive media, t to the complete set of hardness in accordance with technical specifications is accomplished during 10-20 days.

Models were placed before the following media:

• solution and the pair of the alkali Of naOH 40%;
• solution and vapors of acid HCl 27%

The models of stamps B and before tested during 80 days at room temperature with normal [uloviyakh].

Results of the tests:

Stamp of the enamel	Medium	% the swelling	Durability across the 4-[khballnoy] system	Note
Before	Solution of the alkali Of naOH 40%	1,82794	the completely steadfast	Models outwardly did not change
Before	Pairs of the alkali Of naOH 40%	0,8146	the completely steadfast	Models outwardly did not change
Before	Solution of acid HCl 40%	more than 20	not steadfast	Models of [nabukhli], in the phials the acid
Before	Vapors of acid HCl 40%	1,99407	steadfast	Models decolorized
B	Solution of the alkali Of naOH 40%	3,1568	steadfast	Without the changes
B	Pairs of the alkali Of naOH 40%	0,7541	the completely steadfast	Without the changes
B	Solution of acid HCl 40%	more than 25	not steadfast	The models of [nabukhli], appeared the bubbles
B	Vapors of acid HCl 40%	2,6689	steadfast	Without the changes

The enamel “OF [UNIPOL]” of stamps B and before possesses high chemical stability to the action of solutions and vapors Of naOH, vapors of hydrochloric acid is not, however, steadfast before the solutions HCl. Enamel is maintainable, simple before the application relative to other paints, [yuolee] it is technologically effective. It has the lowered requirements at the point of the surface preparation under the coloring, it possesses the possibility of putting on the old coatings.

The fire-retardant paint “OF [UNIPOL]” of stamp [o] has limited application on joint stock company “caustic” and the complex of tests at the point of moment of technical conference it did not undergo.

They solved: About the results of experimental-industrial tests to recommend priming enamel [UNIPOL] of stamps B and [v] for the anticorrosive protection of equipment and conduits of joint stock company “caustic” with exception of the action of the solutions of hydrochloric acid.
