Abstract

A method of making sleeve inhibited polyethylene film consists in extruding the melt of polyethylene plasticized by the mineral oil at the ratio of the polyethylene and the mineral oil equal to 75-85:25-15, correspondingly, with subsequent bulging of the thus produced plasticized polyethylene sleeve with the air and feeding inside the sleeve a volatile oil-solvable corrosion inhibitor.

Larger disruption of the product due to inhibition of bathtubs resulted in the preparation of methods that were incurred due to the incurrence of incidents. The method for the manufacture of a manual inhibition of a polystyrene film containing a volatile inhibitor of ores is known: a mixture of non-organic salt: silamine, β> -cyclohexylammonium nitrite, nitrosodicyclohexylamine.

DETAILED DESCRIPTION OF THE INVENTION The basic task of the invention is to develop such a method of manufacturing a manual inverted, inert, inverted.

The essence of the proposed method could be clarified by proceeding from the following. The industrial plastic film makes it possible to use the most convenient day, the main part of which is available

25 industrial-grade matrix filled with liquid-filled plastic. Particle sizes are reported and are 10-30 microns in size. Аче On the other hand, in order to get the most out of the day, on the basis of polyethylene, mineral oils are used, with which they are combined with oil

After the film and the formation of a commercial matrix, the inhibitor is released at the same time as the plastic.

As it was said above, in the case of industrial processing, plastic films are used in polietilen and mineral oil in a mass ratio of 75-85: 25-15. The oil content in the tank should not be less than 15 wt.%; . An increase in oil content of more than 25 wt. inappropriately, in general, physical and mechanical ones are reduced, in particular, ordinary films, and the properties of plastic films.

When spraying a liquid inhibition in an electric power, it is recommended that you use the following modes: a pressure of 2-10 kP / cm, an acceleration of 15 to 40 minutes.

Β The result of an inhibition of the film in the film is found to be disadvantageous, which in ^χ improves the film’s film properties. Increase the voltage for a value higher than 10 Β / cm for a different, simpler way, and thus the degree of saturation of the inhibition is not increased. From the analogous systems, the upper and lower parts of the range of spraying of inhibitors were selected. At a spray rate of less than 5 g / min, an increase in inhibitory concentration is not sufficient to increase the incidence of pearls and high respiratory distress, and - b -

The best variant of the invention The proposed method for the manufacture of manual inhibited film is carried out by the following 5 devices. Plastered with mineral oil, it is polystyrene which is ejected in the form of a sleeve through a slotted head. A heated outlet with an oil-resistant volatile inhibitor connects a hose (pipe) to the central outlet, but it can be vented

10 for blowing, the hose will be delivered through the receptacle with steams of flying injector. The exhaust Wengil air is disposed of with an inhibitor, which is caused by the ingress of exhaust air through the vehicle.

15 voua with the inhibitor must communicate with the internal cavity of the inflated hose. The inhibitor is supported at 80- Ι00 ° C, which ensures its intensive evaporation and decentralization of the internal charge. .

25 discrete or needle-operated), which are supplied with a high potential for accessibility. An externally-minded head is reluctant. Due to the widespread availability of electrified parts, it is possible to charge a large amount of electricity, to reduce the risk of dust from the particles

In general, the inhibited dietary film obtained by the present service is the same as the case

25 physical and mechanical properties, as well as in the case of an external relation, meet the requirements of the manufacturer, which are subject to qualification. It provides long-term protection of products made of black and non-ferrous metals from the atmosphere, and the values of the speed of the movement

30 (2-5) .10 g / (m ² .hour) means the lack of practical metal at the end of the film. Otherwise, the proposed method of use in the process and the apparatus is sprayed.

Intended use

35 Dummy inverted polyethylene tape, manufactured by the proposed service, may be used - 14 - it is used in the form of a β-consumer-friendly material for industrial protection of metal products from the United States and the United States.
