Abstract

The invention relates to vacuum technology and can be used for the technological cleaning of polymer products With simultaneous diffusion stabilization of their surface. The aim of the invention is to improve the processing quality of polymer products. For this purpose, the installation contains a chamber connected to a vacuum pump, the branch pipe of which is mounted in its upper part and placed above the level of a stabilizing liquid. A tube is placed at the bottom of the chamber, one end of which is made with slits. The other end is curved to be placed above the level of a stabilizing fluid and provided with a throttle valve for communication with the atmosphere. When the installation is in operation, vacuuming is performed with simultaneous leakage of atmospheric air through the slots into the layer of stabilizing liquid. At the same time, the entire mass of the stabilizing liquid is filled with air and moves it to the discharge zone, which makes it possible to improve the quality of stabilization of polymer products. 4 il.

Description

The invention relates to vacuum technology and can be used for the technological cleaning of polymer products With simultaneous diffusion stabilization of their surface.

The purpose of the invention is to improve the quality of processing of polymer products.

FIG. 1 shows the installation, general view; in fig. 2 — node I in FIG. one; in fig. 3 - container for products in a perspective view; in fig. 4-node II in FIG. one,

Ustnozawak contains chamber 1, with pipe 2. Sed .. on the gear pump 3 through a magnetic vacuum valve 4 with a tank 5. 5 is equipped with a magnetic vacuum valve 6 with a pipe for draining the stabilizing fluid. On the side wall of chamber 1, a pipe is mounted with a magnetic vacuum valve 7 connected to a vacuum pump 8, the branch pipe 9 of which is mounted in the upper suit of chamber 1 to be placed above the level of a stabilizing liquid. Chamber 1 is provided with a tube 10. One end of which is made with slots 11 for leakage of atmospheric air into a stabilizing liquid and is located at the bottom of the chamber 1 /

The free end of the tube 10 is curved to accommodate a higher level of stabilizing fluid and is provided with a throttle valve 12 for communication with the atmosphere. On the side wall of chamber 1, on the upper side

but a stabilizing fluid is mounted a guizo device 13. Kamsre 1 is equipped with a drive with a sealed cover 14, which is equipped with a drive (not shown). Camera 1 is also equipped with a drive (not a peak, - - h). Samara 1 is also connected to fan ii, g.1.rsdst 1m valve 16. Fan 15 is equipped with heating elements 17 for heating the air entering chamber 1, into which are placed polymeric products 18. located about container 19c shelves and holes 20. The container 19 is loaded into the chamber and closed with a lid 14 having seals 21 to ensure tightness.

The installation works as follows.

After loading the container 19 with polymer products 18 and closing the cover 14, the chamber 1 is filled with gear pump 3 with stabilizing fluid to the level of the visual device 13. Thereafter, the composition is evacuated for 5-7 minutes. at the same time, the temperature of the stabilizing fluid is 90 ° C, and atmospheric air flows through the throttle valve 12 and the slots 11 of the tube 10, saturating the stabilizing fluid and moving into the rarefaction zone above its surface. The groups of molecules of the stabilizing fluid, moving, affect the product 18, improving the process of their stabilization. Then, the composition of the stabilizing liquid is drank through the magnetic vacuum valve 6 in ba 5. After that, the valve 16 is opened and the air heated by the heating elements 17 is injected to 160 ° C. The heat setting is carried out for about 30 minutes. After that, additional evacuation of parts 18 is performed, lid 14 is opened and container 19 with parts 18 is removed. To adjust the intensity of additional evacuation, throttle valve 12 is opened. Modes of cleaning polymer products 18 and simultaneous diffusion stabilization are selected on the basis of experimental studies.

The composition of the liquid includes an aqueous emulsion, wt.%:

Freon oil9-20 Oleic acid h 10-11 A mixture of poly-styrene-glycine esters of dead fatty

alcohols 0,5-2.0 25% raspor

ammonia 0, 1-05 Water Else Else The following ratio of the components, wt.%:

Hydroquinone 3-7 Water emulsion 93-97 The use of a plant for production conditions improves the quality of stabilization of polymer products by evacuating the stabilizing liquid followed by air flowing into it, each molecule of stabilizing liquid absorbing air particles, i.e. air and immediately give it to the following molecules that need it. The whole mass of the stabilizing fluid is filled with air and moves it at the level of molecules to the vacuum zone until it reaches atmospheric pressure.

During the evacuation and leakage of a stabilizing liquid, the energy of its molecules is used to perform the work of cleaning products.
