Cement tile manufacturing process 1. Ingredients:
Raw materials for the production of cement tiles must be stirred by a roll-roll forced mixer. The mixing time is 5 to 10 minutes. The 350-type mixer provided by this production line can meet the above requirements. Generally, each mix is ​​based on cement 5050 (one pack). With the following:
Ratio of raw materials to plastic sheet ratio: (cement: aggregate) in 1:1.5 to 2.0 (weight ratio)
Water-cement ratio: (water: cement) Master 1: 0.25 to 0.35, depending on the specific additive species. The water should not be too much, otherwise it will cause the tile blank to die, loose, etc. If the water content is too low, the material has less fluidity and the appearance quality of the blanks is reduced.
The mud content of the raw materials used shall not exceed 1%, otherwise it will affect the product quality.
2. Molding:
In production, molding is extremely important. After stirring, the material must be filtered and filtered out in the form of water to form a rigid, hard billet. Requirements:Pressure pressure more than 100 tons (more than 13Mpa pressure gauge), pressurization time not less than 3.0 seconds.
The filter used in the lower mold must be replaced in time, usually two or three times per shift. According to the water content determined by pressure filtration, if the filter oil is damaged, the filtered water will become cloudy, and the cement in the material will be lost along with it, and the quality will decline. Therefore, it must be replaced in time.
Three. Appearance:
The formed green billet must be sharp and angular, the surface smooth, delicate, obviously dry and hard, and the oil body strength of a certain, will not break in the Valto board.
4. Conservation:
Wafer blanks are naturally cured on pallets for 24 hours after molding, and moisture and heat preservation should be observed. On the second day, the preliminarily solidified marbles can be removed from the pallets and placed on the yard for natural conservation. The first day of the week should be taken care of by watering, and sunny and dry weather should be sprinkled more.
Wayi stands upside down, 3-4 floors. 28 days after delivery.
5. Spray:
The color cement tiles are prepared by coating various special color tile coatings according to the customer's needs on the ordinary cement tiles after curing and hardening.
The key to spraying: The tile coating used must be of reliable quality and durable in color. Tiles must have sufficient strength after curing.
The billet must be dried before spraying (the moisture content is not more than 2.0%), and the floor must be dusted. Spray the primer for the first time and then dry it. After the tile blanks are spray dried, they become colored cement tiles and can be shipped from the factory.
