PROMSYSTEMS

Glass powder - homogeneous mass, white (gray or other color), approximately similar to flour, which is made by prolonged grinding of glass with the addition of auxiliary components. The main skill of our Private Enterprise "PROMSYSTEMS" - This is the production of electrovacuum glass powders, which are widely used in the electronics industry, we can produce Borosilicate, Soda-lime, Low or High temperature sealing glass powder. Areas of use: - Glass spy with various types of metals for instrument cases; - The need for increased isolation of products from external, aggressive environmental factors. - As a connecting substance; - As any kind of filler; - Modifiable additive;

Borosilicate glass - contains boric oxide as well as several other ingredients in specific proportions. The inclusion of boric oxide results in a glass material with excellent thermal properties. The material has a different coefficient of thermal expansion and very high resistance to thermal shock depending on the type of glass and customer requirements. As a result, it retains its dimensions across different temperatures and resists cracking and shattering when exposed to rapid temperature changes. Applications of borosilicate glass: - Thermal insulation. Borosilicate glass can be used to withstand high temperatures when compared to soda lime in severe applications. - Ceramic bond. Borosilicate glass is commonly used as an additive for the manufacture of high-strength workpieces that include mixing components with ceramics, abrasives, or other chemical compounds. - High-intensity lighting. Membranes used in high-intensity lighting systems are often made from borosilicate glass.

Private Enterprise "PROMSYSTEMS" manufactures glass to metal seal beads of different standard sizes and shapes to order. They are used for the production: sensors, tecs, power semiconductors (thyristors, diodes), feedthrought and other microelectonics. These are our standard based glasses with a coefficient of thermal expansions (Borosilicate, Soda-Lime, Titanium, etc): - 2.5-3.8 ppm/C; - 4.8-5.2 ppm/C; - 7.2-8.3 ppm/C; - 9.0-10.5 ppm/C;

Private Enterprise "PROMSYSTEMS" produce preforms glass to metal seal of different standard sizes and shapes to order. They are used for the production: hermetics or millitary connectors with different standards (working temperature, hermetics, waterproof. etc). These are our standard based glasses with a coefficient of thermal expansions (Borosilicate, Soda-Lime, Titanium, etc): - 2.5-3.8 ppm/C; - 4.8-5.2 ppm/C; - 7.2-8.3 ppm/C; - 9.0-10.5 ppm/C; - In the production of glass preforms, we use glass of exceptional quality, in accordance with the regulatory and technical documentation for each brand; - Drawing must be attached. It is necessary to indicate with limit: 1. Outside diameter; 2. Inner diameter; 3. Height; For example: Preform (materials what you need) D1 = 3.2 +- 0.2mm, d2 = 1.4 + 0.2mm, h = 2.2 +- 0.2mm. We are reasdasdady to take on the development of new standard sizes from any glass at the expense of the customer;

Glass rods (blocks) - a type of product made of pressed powder based on glass, designed for fastening and insulating the electron-optical systems of picture tubes and special cathode-ray tubes.

The method of preparation of glass-based press powder is the intellectual property of the enterprise since its inception. For its preparation, only high-quality components are selected from those offered on the market. The glass used for the preparation of the press powder meets the requirements of ISO:9001 in terms of chemical composition and physical and chemical properties . As part of the press powder, the content of iron oxide should be no more than: for glasses G0025, G0048-50 = 0.4%; G0052-54, G0074-76 and G0091-93 = 0.55%; The minium order for one supply is from 100-150kg. When ordering, describe the technical characteristics of the glass (CTE, temprature resist), glass grade or other technical spesification. An example: Granular powder (CTE=4.9, T=-70°..+550°C) 150kg or your other characteristics. The warranty period is established for one year from the date of dispath of the product to the consumer enterprise.

Glass cements are lead-containing glass powders that are used for soldering electrovacuum glasses, kinescopes, etc. They tend to crystallize during a certain heat treatment. Solder/sealing glass powders unlike glass cements, can be heated and cooled several times, as usual glass. PS is a composite powder that is intended for soldering electrical boards or for sealing cathodoluminescent indicators with Low Temperature Sealing (415-435C°). The warranty period is set for one year from the date of shipment of products to the consumer enterprise.
