In order to proceed with the manufacture of tiles need rubber or polymer forms. Of these forms, the tile is easily removed after the frozen. The most durable is rubber, since 500 molding cycles are maintained, plastic – 250. And polyuritanis – 100. Before filling the form, it is better to treat the OPL-1 pool. If the lubricant will contain petroleum products, then the form will collapse. It is worth noting that in the production of such products as ventilated facades, other materials are used.
Concrete for tiles is prepared in the usual way. It is better to use concrete mixer. Mix the pigment with sand, then add cement and crushed stone. Additives and water add last. In order to increase the strength of concrete, polypropylene, polyamide or glass fibers are added (1kg per 1m cubic).
Mold tile in vibrationtole. In order to save the pigment, only 30% of the front surface color. The rest of the shape is filled with an unpainted mixture.
Tile dried at a temperature of at least +20 degrees 24 hours. For uniform grazing, it is covered with polyethylene.
Tile remove from forms on a vibrating table (platform). Before promoting the form, it is better to warm up in water at a temperature of +50 degrees. This will increase the life of the forms and will reduce the marriage.
Then the tiles are laid out onto pallets, covered with polyethylene and dried. Fully tile enhances in 28 days.
