St. Petersburg Mica Factory

Factory Organization

A mica factory was established in Leningrad in 1925 under the name Mica Factory No. 2 for the manufacture of micanite and products from micanite at 12 Prylukskaya Street . In 1930, at the address of Rimsky-Korsakov Ave., 7 , another factory was organized, Mica Factory No. 1, for the production of plucked mica. Factories were created to meet the needs of radio engineering in the years of the post-revolutionary industrial boom and laid the foundation for the mica industry in Russia .

War years

During the war years from 1941 to 1944, both factories were partially evacuated to the city of Asbest, Sverdlovsk Region , where they continued to produce mica products. In the besieged Leningrad in the reduced size of the factory worked all the years of the war. The order of the factory director M.K. Galaktionova from June 1, 1943 on the unification of the 1st and 2nd Mica factories into one with the location of the department at Rimsky-Korsakov Ave., 7, has been preserved . After the evacuation in 1944, the factories were again divided into the 1st and 2nd Mica factories. In the archival documents ^{[1] [ specify the link (already 580 days) ]} , preserved from those years, the whole history of the blockade is reflected: withdrawals to the front, deaths in the besieged city, food distribution, protection against looting, fire brigades, bomb shelters, hard work, the work of children in the workshops, and closer to the year 1944 of their return, the celebration of the anniversary of the October Revolution, the assessment of destruction and loss, and restoration work. Factories shared the fate of their hometown and worked heroically throughout the war years.

Post-war Soviet period

In the postwar years, the need for factory production increased even more. At the end of the 40s, the number of both enterprises was about 500 people, and by 1956 reached 1000 people.

In 1953, both enterprises were finally merged into one under the name Leningrad Mica Factory. Mica factory No. 2 was continued in workshop No. 5, producing mica paper, mica tapes and mica, and Mica factory No. 1, now workshop No. 2, specializing in natural mica products and electric heating elements. Premises in the city center did not meet the needs of enterprises. The archive documents and letters to the leadership, which state the need to expand production facilities. In the early 60s, a decision was made to move to the city of Kolpino, where a site of 12.5 hectares was allocated for the Mica Factory near Izhora factories. The construction of the Mica Factory in the city of Kolpino began in 1963 and continued until 1976 . At this place, the Mica Factory is located now. The factory was awarded the Order of the Badge of Honor in 1975 .

Modernity

In 1993, the Mica Factory was corporatized and turned into CJSC Mica Factory. In difficult times of economic decline during the years of perestroika , the St. Petersburg Mica Factory continued to produce insulated mica products in a reduced volume.

After 2008, the company's products are again in demand and meets the requirements of the Russian electrical market . At the enterprise, reconstruction and modernization of equipment was carried out, new products are being developed. One of the leading areas of activity is the production of dry building mixes based on expanded vermiculite, which has heat-insulating and sound - insulating properties.

Electrical Insulation Products

Mica papers, mica tapes, mica, stamped products from mica, heat-resistant and arc - resistant materials are used for electrical insulation of electrical machines.

Natural Mica Products

Sheet mica, stamped products from natural mica, hydrothermal mica SMOG for high pressure boilers .

Mica-based electrical heating elements

They are used for electrical insulation of industrial and household electrical appliances and machines.

Crushed mica phlogopite

It is used as a filler:

• drilling mud while drilling wells;
• mixture applied to welding electrodes ;
• slag-forming mixtures in metallurgy;
• asphalt mixes;
• rubbers, plastics, varnishes, paints, primers, glues, ceramics, wallpaper;
• plasters and putties .

Expanded Vermiculite

Expanded vermiculite is an expanded hydrated mica, is a loose granular light porous material with a particle size of from 0.5 to 10 mm. It has heat-insulating, sound-insulating properties, fireproof , inert , harmless.

Scopes of Expanded Vermiculite

• In construction, for thermal insulation, sound insulation and ensuring fire resistance of the surface as a part of various building mixtures: concrete, masonry mixtures, plasters, floor leveling agents ^[2] ; as part of building boards; as a bulk heat insulator .
   

  Expanded Vermiculite
• In metallurgy for thermal insulation of the profitable part of ingots and equipment
• In agriculture , crop production , floriculture is called agroermiculite. Regulates moisture and ion exchange in the soil, is a carrier of fertilizers and nutrients . It is used to improve the properties of soils , hydroponics , the environment for storage and transportation of seeds , flower bulbs , vegetables and fruits. It is added to the composition of ready-mixes for industrial and amateur floriculture .
• In livestock and poultry as an additive in feed and bedding material.
• In ecology for collecting oil from water bodies and soils
• In the chemical industry as a filler in plastics , rubber , varnishes and paints, sorbent of organic and petroleum products , environment for storage and transportation of active chemicals.
• For storage, packaging and transportation of glass, appliances, liquids, active chemicals, vegetables and fruits.
• In the automotive industry as part of brake pads and other friction products .
