(Changed edition, Amendment No. 4).

4.2. The dimensions of paronite are determined according to GOST 24039.

The dimensions of the gaskets are determined in accordance with the drawing.

4.3. From each selected sheet the following is cut out for testing:

By pi. 2.5 (Table 4, indicators 1, 3, 4, 5, 6), 2, 8 - one sample;

By i. 2.5 (Table 4, indicator 2) - two samples;

4.2, 4.3. (Changed edition, Amendment No. 3).

4.4. The density of paronite is determined according to GOST 24039, and deviations according to individual definitions are allowed by no more than 10% from the norm.

45. Determination of tensile strength conditions

Samples measuring 20x110 mm are cut out with a maximum deviation of +0.5 mm in the direction transverse to the rolling. The samples are kept for (60+5) minutes in a drying cabinet at a temperature of (110+5) °C, and the samples must be positioned in such a way as to ensure free access of air over their entire surface. Then the samples are cooled for at least 30 minutes in a desiccator according to GOST 25336, filled with calcium chloride according to TU 6-09-5077, at a temperature environment(23^) °С.

The thickness of the samples is measured.

The samples are clamped in a tensile testing machine with a distance between the clamps (50+2) mm and a moving clamp speed of (250+10) mm/min and they are broken.

The samples are broken no later than 10 minutes after removing them from the desiccator. If the sample ruptures at the point where it is clamped, the test result is not taken into account and tests are carried out on a new sample.

The error of changes should not exceed 1% of the measured load.

Conditional tensile strength (G) in megapascals (kgf/cm2) is calculated using the formula

where P is the load causing the sample to rupture, N (kgf);

S is the cross-sectional area of ​​the sample before testing, m 2 (cm 2).

The test result is taken as the arithmetic mean of the results of all determinations, rounded to the nearest whole number, while deviations from the norm for individual determinations are allowed by no more than 10%.

(Changed edition, Amendment No. 4).

4.6. The increase in the mass of paronite in liquid media is determined according to GOST 24037, while deviations according to individual definitions are allowed by no more than 10% from the norm.

(Changed edition, Amendment No. 4).

4.7. The reduction in mass in liquid media is determined according to GOST 24037 on samples measuring 20x20 mm with a maximum deviation of +0.5 mm.

(Changed edition, Amendment No. 5).

4.8. The compressibility and recoverability of paronite are determined according to GOST 24038, while deviations according to individual definitions are allowed by no more than 10% from the norm.

(Changed edition, Amendment No. 4).

4.9. Determination of sealing ability

4.9.1. Paronite grades PON and PA, PON-A, PON-B, PON-V are tested for compaction ability in a steam environment in a laboratory autoclave of the AP-1 type (Fig. 1).

Nine ring samples of paronite with outer diameter (120+1) mm and inner diameter (80+1) mm, coated with oil-graphite paste (composition: mineral oil with kinematic viscosity at 100 °C (6-11) m 2 /s 65-85% and graphite according to GOST 5420 or GOST 5279 15-35%) are clamped between the flanges (steel 40X according to GOST 4543) of the collector. The presence of lubricant on the end part of the samples is not allowed.

(Changed edition, Amendment No. 4).

Tests are carried out at a steam pressure in the collector (10+0.5) MPa [(100+5) kgf/cm 2 ], pressure on the samples (22.5+0.5) MPa [(225+5) kgf/cm 2 ], collector temperature (450+10) °C and test time (30+2) min.

The samples ensure the tightness of the sealed joints if there is no steam leakage during the test.

4.9.2. Paronite grades PON, PMB, PMB-1, PA, PON-A, PON-B, PON-V are tested for compaction ability in liquid media in a laboratory autoclave type AP-2 (Fig. 2).

Kerosene is used as a control liquid.

Nine ring samples of paronite with an outer diameter of (120+1) mm and an inner diameter of (80+1) mm, coated with oil-graphite paste, are clamped between the flanges of the manifold. The presence of lubricant on the end part of the samples is not allowed.

Tests are carried out at a pressure of the liquid medium in the reservoir (15+0.5) MPa [(150+5) kgf/cm2], while the pressure is gradually increased every 15 minutes by (2.5+0.5) MPa [( 25+5) kgf/cm 2 ], sample pressure (32.4+0.5) MPa [(324+5) kgf/cm 2 ], liquid temperature (20+5) °C and test time at the specified parameters (30+2) min.

The samples ensure the tightness of the sealed joints if there is no kerosene leakage during the test.

4.9.1, 4.9.2. (Changed edition, Amendment No. 1, 4).

4.10. (Deleted, Amendment No. 1).

General-purpose paronite brand PON (A) is manufactured in accordance with GOST 481-80 from a rubber mixture based on synthetic or natural rubber with the addition of chrysotile asbestos fibers and modifying additives.

Paronite PON (A) is used for the manufacture of gaskets that seal permanent flat connections mechanisms and apparatus. When the paronite gaskets are correctly installed in the sealed assembly, complete tightness of the sealed connection is ensured. The material is produced in the form of sheets with a thickness of 2.0 to 6.0 mm, with dimensions from 500x500 mm to 1500x3000 mm. By agreement between the consumer and the manufacturer, it is possible to produce gaskets according to approved regulatory documents customer.

Paronite PON (A) is the most common gasket and sealing material. It is easy to machine: cutting and chopping. The yield strength of paronite is 320 MPa. At this pressure level, the material begins to “flow”, filling all leaks, sealing the connection. When choosing a paronite sheet, you should correctly determine its required thickness. The thinner the sheet, the more effective the sealing. But on the other hand, the thickness of the paronite should be sufficient to fill the connecting lock - “tenon-groove”, “recess-protrusion”, etc.

Paronite and products made from it can be used in cold, temperate and tropical climates.
