Description

2. The method according to p. I, about tl and h a yu shch and with the fact that sodium fluoride is used as a disinfectant.

one

The invention relates to gardening and forest park management, urban plantings, memorial plantings and can be used in all cases where the clogging of the hollows of trees is needed.

The purpose of the invention is to reduce the embedding time, improving its quality and appearance.

The drawing shows a scheme for filling the hollow with a filling mass and at the same time decorating it.

The filling of the hollows with decoding is carried out as follows.

From the cylinder 1 polyester with pigment and from the cylinder 2 isocyanate with disinfectant through hoses 3 by pump 4 is fed to the spray gun 5. At the exit from the nozzle 6 of the gun, all these components are mixed into a common Jet, after which the spray of aerosols is directed to the hollow 7 8. As a result of the mixing of the initial components, the resulting filling mass (polyurethane foam) 9 fills the entire hollow cavity. Then, continuing the spraying, create a bulge from the sealing mass that extends beyond the hollow plane. For non-hardened polyurethane foam, the template 10 is pressed into the embossed decorative image 11 or the elastic template 10 (5-10 mm thick) with anti-adhesive lubricant 12 on the inner surface attached to the tree. The space remaining between the sealing mass and the template is filled with polyurethane foam through special places 13 (holes) in the template. After the filling mass has set, the template is removed for further multiple use.

PRI m, e r. Polyester with a pigment in a ratio of 1: 0.02 is mixed in one cylinder, and isocia3 in the other. The method according to claim 2, wherein sodium fluoride is used in the form of a 4% aqueous solution.

nat with a disinfectant in a ratio of 0.85: 0.015 (the volume of polyester in all cases is taken as 1). Iron minium is used as a pigment, and disinfectant substance is sodium fluoride of 4% concentration.

Polyester P-7 and Laramol 294 are used to seal the gill, and polyisocyanate B is the isocyanate.

The hollow is completely filled with quick-hardening; the substance is a mixture of these components. The sealing mass is sprayed further to form a bulge extending beyond the plane of the hollow. Then a mask is fastened to the tree trunk - a template that seals the sealing mask. Next, the sprayed mass fills the space between the mask and the bulge on the hollow. After the mass has set, the template is removed. The mass filling the hollow has a uniform composition, a tight fit to

the walls of the hollow, its adhesion to wood is 1.10 MPa. The surface f of the decorative image is smooth, the color is uniform, there are no cracks. The mass of materials used for spraying is 6 kg, and the curing time of the filling mixture is 4 minutes.

B table shows examples characterizing the filling mass at

different ratios of the original components and the quality of decoration of the snipe.

The use of isoretienie allows shortening the duration of the hollow snipe and improving its quality, creating adhesion of the filling mass to wood (as compared with hollow fillings, a clay mixture), as a result of which the hollowing of the hollows is conserved as an environmental protection measure.

volumetric expansion (filling mass increases in volume by 3–20 times in relation to the mass of the initial components) and good adhesion to wood (0.2–1.1 MPa with no adhesion and volume increase in a traditional mud – bitumen mixture); the entire hollow cavity, regardless of its configuration. It gains final strength within 3-5 minutes after mixing the initial components, and a clay mixture for 18- 52 h (at relative humidity: exposure 60 + 5% and temperature 20 + 2 C), filling capacity of the hollow with the proposed tool 12- 21 min., With a mixture of clay, sand and rubble, followed by cement putty 65-92 m (for a hollow of 0.05 m), i.e.
