SU1436665A1 - Method of manufacturing surface light spectrum guides-mixtures based on polymethylmetacrylate - Google Patents

Abstract

The invention relates to the detection of ionized radiation, in particular, to the development of gasoscopic total absorption calorimeters and scintillation counters using optical spectrum shifters, it can also be used in solar power engineering. The aim of the invention is to increase the transparency of the displaced optical fiber. The essence of the method lies in the fact that at the extraction speed of the dyebath from the dyebath less than 3 cm / min, conditions are realized in which the coating film dries out before the light guide rises to a height at which the weakness of the surface tension affects and the coating film begins to drain into dyeing bath. After fabrication of the optical fibers, the coating film is annealed for 10–30 min at 11.0–12 {fc. The coloring of the light guides is carried out in a solution that consists of a dye (pyrozoline or coumarin row), alcohol (methanol, ethanol) and some impurities. The implementation of the proposed method allows to increase the transparency of the optical fibers of the spectrum by 10-20% compared to known methods. 1 ip., 2table. (L C iKWt 4 O5

Description

Illumination refers to T) Igni tation of ionizing and puchrie, in particular, to the work of a full calorimeter 7p full hg1l (m-tsi and scintillion counters using optical fibers, a spectrum that is displaceable, it can be used by 300 or so-and-ontherods). -Technicals where spectrum shifting fibers are used, for example in solar power engineering.

The aim of the invention is to increase the transparency of the blender mixer.

The drawing shows the installation of the CPU implementation of the method.

The installation contains a thermostat 1 with a heat carrier 2 and a thermostatting system 3, a tank (bath) 4 with a dye solution, a billet suspension system 5, an electric motor 6 with a gearbox for removing the light guide 7 from the bath.

With the extraction speed of the workpiece from the bath of 7–3 cm / min, drips are possible, but the medicament removal from the bath avoids the leakage, since the viscosity of the solution is almost equal to the viscosity of the solution and it does not steam from the surface of the extracted fiber. fast enough so that the squeeze film that is formed due to the surface tension during the slow extraction of the hardness film before the fiber rises to the height at which the weakness of the surface tension forces and the alcohol solution begins to drop into Annealing bath is introduced to prevent the appearance of peace cracks (silver) on the optical fiber surface. ;) experiments show that the annealing fiber is not silver after annealing, and while the unheated fiber is practically unbearable h “cut ,. 1-4 months, when extracting 1) zhki mpiae 10 min, silver plating is possible, and 30 min is obviously sufficient to prevent it, Kg) Tokh oh, it should be noted that wrists) - should be done directly: sinning after dyeing. If the annealing is observed after the occurrence of sulfur | mm and, on some optical fibers LM-O V «; M, it is impossible to eliminate the annealing 1 - and (- that is,

Comrade, on the other hand, the visible Cerare disappears, but in both cases the transparency of the optical fiber is lower than before the appearance of silver.

According to the proposed method B capacity 4 with a dye solution composition, wt%:

Ethanol 96.1%

10 Coumarin- 0.125%

Impurities The rest, when the solution temperature is 50 ° C and is kept in solution for t min by means of an electric motor 6 suspension system 5, extracted at a speed of 3 cm / min, followed by annealing of the light guide 7 while in a heat-treating furnace, optical fibers with the parameters specified in Table 1,

20 Under the same conditions, but with a phosphor 1,5-diphenyl-3-styrylpyrazoline, as the dye, optical fibers were made with the parameters indicated in Table 2

25 Fabricated fibers have a uniformly colored, without streaks, surface and are characterized by transparency, greater by 10–20% than spectrum shifting fibers, made from 30 using known methods.
