Introduction of production technology of cement colored tile

Colored tiles include colored cement tiles and colored concrete tiles. We usually say colored tiles refer to cement colored tiles. Colored tiles are newly developed decorative materials in recent years. Its advantages are strong compression resistance and high bearing capacity. Colored tiles have reasonable structure, rich colors, bright surface, good waterproof and anti-corrosion effects and do not fade. Generally, luxury villas will choose to use colored tiles for roof decoration. So how are colored tiles made? Bian Xiao shows you the production technology of cement colored tiles.

The raw materials used in the production of colored cement tiles must be stirred for 5- 10 minutes with a wheel mill forced mixer. The 350 mixer provided by this production line can meet the above requirements. Generally, each stirring is based on 50㎏ (one package) cement, and the ratio is as follows:

A, raw material ratio table

Cement-bone ratio: (cement: aggregate) should be controlled at 1: 1.5 ~ 2.0 (weight ratio).

Water-cement ratio: (water: cement) 1: 0.25 ~ 0.35, depending on the specific admixture. The moisture should not be too much, otherwise it will cause the ceramic tile blank to stick to the mold and loosen. The amount of water is too small, the material fluidity is small, and the appearance quality of tile blank decreases.

The silt content in the raw materials used shall not be greater than 65438 0%, otherwise the product quality will be affected.

Two. Molding:

In production, molding is extremely important, and the stirred materials must be pressurized to filter out water during molding and become hard tiles. Requirements: the pressurization pressure is above100t (the pressure gauge is above 13Mpa), and the pressurization time is not less than 3.0 seconds.

The filter screen of the lower die must be replaced in time, generally 2-3 times per shift. According to the water content of the filter press, if the oil filter is damaged, the water of the filter press becomes turbid, the cement in the filter material loses and the quality drops, so it must be replaced in time.

Three. Appearance:

The formed tile blank must be angular, smooth and delicate, obviously hard, and the oil has a certain strength and will not break on the tile support plate.

Four. Maintenance:

The formed tile blank is naturally cured on the tray for 24 hours, and attention should be paid to moisturizing and heat preservation. On the second day, the preliminarily solidified tile blank can be removed from the tray and placed in the yard for natural curing, and attention should be paid to watering and curing every day in the previous week, especially in sunny, hot and dry weather. Tiles should stand vertically, which can be 3-4 layers. It left the factory after 28 days.

Verb (abbreviation for verb) spray:

Color cement tile is made by spraying various special color tile coatings on ordinary cement tile after curing, coagulation and hardening according to customer's needs.

The key to spraying: the color tile paint used must be reliable in quality and durable in color. Ceramic tile blanks must have sufficient strength after curing.

Before spraying, the ceramic tile blank must be dry (its moisture content is not more than 2.0%) and the surface of the ceramic tile must be dusted. Spray the primer for the first time and then dry it. After spraying and drying, the tile blank becomes colored cement tile, which can be delivered from the factory.

This paper introduces the production technology of cement colored tiles, which makes everyone know more about cement colored tiles. Whether it is colored concrete tile or colored cement tile, they are not only beautiful in appearance, but also much better in practicality than the traditional cement tile rolled with hard concrete. Colored tiles are mainly used in multi-storey or low-rise buildings, especially villas. If you want to know more about colored cement tiles, please continue to pay attention to Bian Xiao, who will do more sorting and introduction for you.
