The invention relates to abrasive pastes and can be used in the jewelry, machine tool and other industries where ordinary and decorative polishing of plastics and other non-metallic materials, mainly amber, is performed.

And pasta is used to polish plastic parts with tools, such as polishing: circles on which it is applied in a thin layer during rapid rotation, circle il.

However, the peculiarity of polishing around is that the parts are processed alternately, and the surface of the part is treated in parts. This explains the low productivity and hinders its growth during polishing operations. Recently, an increasing method has been found for polishing in drums by means of various fillers, in particular wood cubes, on which a polishing lip is held and fixed, and the pile must be held on the filler until the end of processing at least one batch of parts. Closest to the technical essence of the achieved effect to the proposed is a polishing paste containing abrasive (diamond powder), stearin tl wax C2.

The disadvantage of the paste is the uneven distribution between the filler granules, it is poorly retained on the filler - hardwood cubes, filling in n | During the polishing process, the drum, together with the products to be processed, is removed from the working area until the time when the required cleanliness of the surface of the processed products is reached. From the amber, the adhesion of the cubes into lumps is observed. The purpose of the invention is to increase the processing performance of ntar and improve working conditions.

This goal is achieved by the fact that polishing paste containing abrasive, stearin and wax contains, as an abrasive, a plaster paste

and additionally contains pine rosin and petrolatum technical in the following ratio of components, May.%:

Gypsum stonewall 36-57

Stearin25-30

Wax. 4-10

Rosin pine 3-6 Vaseline technical. . 11-18

0 The composition of the paste contains beeswax.

The manufacturing techniques of the proposed paste are as follows.

In a tank equipped with mechanical

5 with a garlic stirrer and thermostatically controlled, the calculated amount of stearin, technical petrolatum, beeswax, rosin is loaded successively. After all the components have been melted and the mixture is homogeneous, dry Ca - 1 / 2NO is added with continuous stirring. The homogeneous molten mass is poured into a container and, in order to avoid sedimentation of alabaster on the bottom, is continuously stirred, cooled until it acquires a greasy consistency, after which the stirring is stopped and the paste cools to a solid.

30 kg of filler - cubes of hardwood size (4-4-12) 1, 12 g-lm, pre-run-in until the elimination of burrs. A portion of the pass5 (You are heated to a liquid state, mixed thoroughly and poured onto the surface of the filler, the drum is immediately rotated and left for three hours. After that

0 another paste is added in the same way and rotated for another 6 hours, after which the test samples prepared for polishing are loaded into the drum, the beads are uncertain

from a natural amber mold, and rotate the drum for 36 hours at a speed of 28 rpm.

The polishing quality is determined by comparing the samples with ethanol, surface finish;

 which meets the requirements for jewelry m.

The initial surface finish of the samples processed in all experiments is the same and corresponds to

Sample 5 - the standard of semi-finished products, enters the polishing operation.

The adhesive ability of the paste is determined visually from Hc1 of the processing of parts to

0 the occurrence of particles with polishing products screened out through the perforated drum wall.
