Proizvodstvo trotuarnoy tiles on technology vibropressovaniya
Pressed trotuarnaya the tile is applied in the Western Europe since 30th years of the XX-th century. For this time, the technology of its production was repeatedly improved and in the end of the XX-th century the German machine-building company “HESS Maschinenfabrik GmbH and Co. KG” has developed and has introduced technology volume moist vibropressovaniya. Analogues of the given technology and it has not been created till now. In the early nineties the last century the Russian company of Open Society "Factory" Red Presya ”» has started to run in the new production program on working out vibropressovogo the equipment for its realisation in the market of Russia and in other countries.
Conditionally production on technology vibropressovaniya can be divided into some stages:
- Preparation of a forming mix.
In betonosmesitelnuyu installation (BSU), namely, in the planetary amalgamator, the raw materials (cement, coarse-grained sand, water) act. Process of preparation of a mix is completely automated. Accuracy of performance of the set recipe, and also the set parametres and the mode of operation are supervised by the operator from the central control panel. The prepared mix acts in the basic bunker vibropressa. - Formation of the basic layer.
The portion of a mix acts on vibrostol where during time set by the computer program there is a process of preliminary consolidation. - Formation of an obverse layer.
During formation of the basic layer in BSU the raw materials for formation of an obverse layer (the cement, the enriched sand, water, a pigment) act. The received mix acts through the basic bunker vibropressa on being on vibrostole and previously condensed basic layer. After that there is a process of the basic consolidation of a mix, and then a mix once again douplotnyaetsya vibroudarom.
Use of hi-tech two-level system of formation allows to achieve first, the highest durability trotuarnoy tiles, and secondly to optimise expenses for dressing (painting) of a tile as the pigment is used only in an obverse layer. - SHtabelirovanie.
The formed items on pallets on a conveyor belt act on a post shtabelirovaniya. Here items are stored in stacks and on special transportno-technological pallets or transported in proparochnuyu the chamber, or maintained in natural conditions. - Steaming.
Trotuarnaya the tile acts in the special chamber with a waterproofing where there is a humidity — 95 % and temperature — 600°S. Finding time in the chamber — 12 hours. Use special proparochnoy the chamber allows to achieve 75 % of durability trotuarnoy a tile of all for 12 hours, in usual conditions on it it would be required not less than 15 days. Thus the technology vibropressovaniya allows to carry out finished goods shipment next day when issued. - Finished goods quality assurance.
Constant laboratory quality assurance manufactured trotuarnoy tiles on vibropressovom the Factory equipment «Red Presnya» STATE THAT allows to exclude delivery to customers of production mismatching requests, and guarantees more than 30 summer service life of items.

Trotuarnaya the tile made by a method vibropressovaniya from moist peskobetonnyih of mixes, at low cost, has clear advantages before traditional pouring of sidewalks by asphalt or moscheniem trotuarnoy a tile produced by a method vibrolitya. The Overwhelming majority trotuarnoy a tile manufactured all over the world, is produced on technology vibropressovaniya. The technology vibropressovaniya consists that vibrating...
