In China's traditional ceramics category, there are many categories, and there is a special category, that is, grass planting bricks , which is a type of traditional ceramic wall tiles. Because of the common texture and delicate texture, it has been widely favored for many years. This type of brick is actually a kind of homogeneous brick, facing brick, and exterior wall brick, but it is finally cut and has a certain groove. This cultivated grass brick looks very integrated and very Beautiful and simple construction, it has become a more popular product in the mall.
How does the development of grass planting bricks? The development of grass planting bricks is relatively late in China. It was first in Germany, followed by Europe, and then entered China. However, it has been favored by consumers since it entered domestic shopping malls. China ’s existing Beijing, Provincial cities such as Xiamen, Xiangfan and Taiwan introduced grass-brick production lines and have been put into production. In recent years, with the skill of the skin, the price of grass planting bricks has continued to decline, and has become a popular product in shopping malls.
What are the standards for grass bricks? The production of this type of brick is mainly to participate in clay and cut it, so the standard of grass planting bricks is not small, so it looks more specific and integrated. At present, the standard of this type of bricks in the mall are: 240mrn × 52mm × 11mm, 240mm × 115mm × 11mm, 194mm × 94mm × 11mm, 190mmx190mm × 13mm, 240mm × 115 / 52mm × 13mm, 194mm × 94 / 52mm × 13mm, etc. Several types.
What are the application areas of grass planting bricks? This type of brick is mainly used for exterior wall decoration of various types. Of course, some grass planting brick standards are also suitable for laying indoor floors in halls, stations, waiting rooms, restaurants, etc. Some thicker ones can also be used. For the laying of some public places, such as sidewalks, parking lots, etc. In general, grass-planting bricks have been widely used in China because of their unique advantages. In many places, the shadow of grass-planting bricks can be seen in public places. I believe it will be used more and more widely in the future.
At present, the grass-brick planting malls in China are relatively complicated, and there are not many large manufacturers, but more small manufacturers and workshops. The quality of the planted bricks produced by these manufacturers cannot be guaranteed. Therefore, when buying grass bricks, the first thing to look at is the brand. Select some large domestic manufacturers and trust the power of the brand.
2. Check the appearance of grass planting bricks:
At present, grass planting bricks in China are roughly divided into two types. One is to permeate through the pores on the outer surface of the brick, and the other is to permeate through the gap between the brick and the brick. When we see the grass planting brick, the first thing we see is It is the appearance of bricks. The more inferior grass-bricks on the market are rough in appearance and the pores are very large. The cultivated grass-bricks have a relatively low service life and short water-permeability moments. Why do you say that? Because of the large water-permeability characteristics It is simply blocked by dust. Once it is blocked, it loses the function and value of the grass planting brick. However, the cost of this large-pore grass planting brick is relatively low. We should choose the kind of very dense grass planting brick. This cultivated grass brick The long time of permeation and long service life. A grass planting brick made of sand is more popular on the market today.
3. View the permeation aging, service life, permeation speed and other data:
The criteria for inspecting the quality of grass planting bricks are: 1. See how long the water-permeable time of the cultivated grass bricks is; 2. See the comprehensive service life of the cultivated grass bricks; 3. See the water-permeable speed of the grass-planting bricks. These 3 standards are the litmus test for the comprehensive quality of grass planting bricks.
4, look at the price:
The price and cost have always been our concern. It is the so-called price and goods. It makes sense to be expensive and cheap. In fact, the price selection is also very simple. If you are interested in the immediate interests, you can choose ordinary grass planting bricks. If you are interested in long-term interests, then choose good quality grass planting bricks to ensure 10 years of water permeability and the quality is very good.
Do we know what to do when the grass planting bricks are hanging white? The following is a detailed introduction of Wanxin Cement Products. Poor paving simply occurs when the brick surface hangs white, which is collectively referred to as "pan-alkaline". Once this phenomenon occurs, you must first understand the true cause of pan-alkaline planting of grass-plant bricks in order to handle and prevent it.
I. Causes and principles of alkaloids caused by poor planting of grass planting bricks:
a. Reasons for construction materials:
1. The bottom plastering layer of the wall contains a higher content of free alkali.
2. The binder and the jointing agent have a higher content of free alkali.
b. Reasons for the construction process: When paving, the full coverage of the adhesive on the reverse side of the grass planting bricks is insufficient, forming voids; the joints are not full, and cracks occur, causing rain to seep in.
c. The principle of pan-alkali occurrence: due to the above-mentioned bottom layer, bonding data, jointing data, and paving joints are not full, after the rainwater enters the reverse side or gap of the brick, it is separated from the bonding data and jointing data. Alkali chemical reaction occurs, white flowers occur, soak out through the brick gap or brick surface, forming pan-alkali.
Second, the methods to effectively prevent the occurrence of pan-alkaline after the planting of bricks are:
a. The bottom layer is boring, it is better to spray the anti-seepage material first;
b. Select low alkalinity adhesive and jointing agent;
c. During the construction process, the adhesive is full and the joints are dense. After the paste, the joints should be cured after the adhesive is completely cured, usually no less than 48 hours, and the best is more than 7 days; prevent construction in rainy days. , Especially to prevent sew in rain.
3. The treatment method for alkalescence of grass planting bricks is as follows:
a. Sunny and clean, wash the brick surface with oxalic acid, and rinse with water;
b. After the brick surface is dried, spray a layer of colorless and transparent anti-seepage agent, so that the external water cannot enter the reverse side or groove of the brick, and the necessary ingredient to prevent the occurrence of pan-alkali: water. (Because the humidity of the air is high in rainy days, it is not suitable to operate in rainy days)
c. After spraying the anti-seepage agent, the effect of the brick surface will not be affected.
