The mechanical properties of grass planting bricks are relatively sensitive to the process conditions. The compressive strength and flexural strength increase with the decrease of the particle size of the material, and are proportional to the firing temperature. The participation of bentonite can not only improve the dry strength of the green body, but also improve the mechanical properties of the product.
What is the performance of grass bricks, what are the water permeability and porosity related to?
The smaller the particle size of the material, the higher the firing temperature and the better the abrasion resistance; the participation of bentonite can improve the abrasion resistance of grass planting bricks; the greater the molding pressure, the better the abrasion resistance of planting grass bricks.
The change of the water permeability coefficient of grass bricks has a great relationship with the firing temperature, but it is not greatly affected by the particle size composition of the material. In the case of a narrow particle size distribution, the influence of the molding pressure on the water permeability coefficient is small.
The porosity of grass planting bricks decreases with the progress of firing temperature, and the influence of molding pressure on it is not obvious.
1. When the slurry is soiled by hands, it is strictly forbidden to scratch (or touch) the appearance of the brick with soiled hands to avoid adding cleaning costs.
2. If the slurry is dirty enough to crack the appearance of the brick, it cannot be wiped wet. When it is dry, it must be scraped off with a knife. Otherwise, it will become more and more dirty.
3. After pasting and splitting the bricks, if you need higher and better results, you can use a brush to dip the "MCM soft porcelain glaze" and evenly paint the MCM soft porcelain wall from top to bottom, the painting process is tight. Follow with a dry towel to dry the surface glaze. Do not allow the surface glaze to hang or become uneven. During the brushing and wiping process, you must frequently change new wipes to avoid more and more dirt and dust on the wall, causing secondary pollution.
