How to make bricks 5, how to make bricks

When firing, it is divided into anaerobic and aerobic.

In the aerobic state, because the soil contains iron, it reacts redox with oxygen at high temperatures to become ferric ions, which are red and crimson, so the bricks look like that.

In the case of anaerobic firing, the traditional practice is to close the brick kiln, fire at high temperature, and when it is almost successful, water is poured inside, and the water reacts with iron at high temperature.

This kind of brick is called green brick! Most of the palaces, temples, and stupas in ancient China ......It's all bricks like this, because it's more durable than red bricks.

The brick making process, the original production method, is the first time I have seen it, and I have seen it for a long time.

Step 1: Prepare the required materials:

1. Vermilion and brown advertising pigments; (Watercolor paint should also be available, in short, it can be colored, what is cheaper, what is used, and the pigment is the big head in the total cost).

2. Cooked gypsum powder. (Gypsum powder is sold in many decoration stores, and special attention should be paid to buying cooked gypsum powder, which cannot be watered and solidified.) Raw gypsum powder is crystalline, and cooked gypsum powder is powdered. ）

The second step is to find a piece of cardboard, cut it into long strips of the same width and length according to the size (the width of the strip is the height of the brick to be made, and the length is the length of the brick), and then superimpose the strips and intersperse them into a mesh brick skeleton The third step, adjust the color and add gypsum powder. The steps are first water, then color, then gypsum powder. It is important to note that:

1. The color should be darker than the color you want the finished product to be, because the gypsum powder is white, which will dilute the color; When adjusting the color, the ratio of red to brown is about 5:1, otherwise it will be too red and there will be no smell of brick and earth. 2. After adding gypsum powder, you can't add too much at one time, and you should continue to add it after the last complete stirring.

The ratio of gypsum powder and water is about 2:1, the larger the ratio, the faster the gypsum solidifies, the fourth step, the third step of the prepared gypsum is smeared on the cardboard skeleton, the thickness of the coating is determined according to the actual situation, scrape the surface with a blade but not too flat, the surface should be flat and rough, and finally wait for him to dry.

1.Take the clay and put it in a mixer to break it, before that, you need to dry the debris on the way, so as not to affect the quality of the bricks, and water will be added when mixing. Increase the adhesion of the soil.

2.Before the mixed clay is put into the extruder, there will be a special person to test the amount of moisture in the clay and the degree of polymerization by hand.

There will be a water pipe, and again, based on the real-time observation, the decision will be made whether to add water. This is a very important part.

3.The clay is extruded into rectangles by an extruder, conveyed through a conveyor belt, and cut into bricks like a cake. At that time, the machine cut about 15 bricks in a row.

Then it was pushed to the wooden board in front, and the two masters next to it lifted the wooden board and the bricks on it to the flat car waiting in front, and then the other masters pulled the flat car to the place where the bricks were stacked and stacked in a unified manner, and dried them

4.After the bricks are dried, they are more solid and hard, (it is not easy here, and the bricks should be covered with a straw curtain in case of rain, and the bricks that have been poured by the heavy rain are basically not usable), and the place where the bricks are stacked is called "hang" in our dialect at that time.

5.After a period of drying, the bricks are fired in a brick kiln at a temperature of about 950 to 1,100 degrees Celsius. Between.

The process flow is:

1. Soak the soil, pour water on the clay, and soak the clay thoroughly with water

2. And mud, through full mixing, so that the viscosity of the soil reaches the maximum, to achieve a moderate moisture content, (in the past, there was no mixer, all to manual operation);

3. Beat the blank, roll the outer ring of the mud ball with sand, and put it into the billet bucket, (the billet bucket is a mold for making bricks), and pour it out in the cool billet field;

4. On the shelf, it is a process of drying blanks;

5. Loading the kiln is to stack the dried adobe in the kiln;

6. Kiln firing, firing adobe into bricks;

7. Drinking kiln, the adobe has been fired into bricks, on the top of the kiln, sealed with soil, and surrounded by soil into a circle, and then, poured water into the soil circle, in order to achieve the method of water catalytic transformation to make the fired turn cyan.

1. The bricks are made of clay, and the clay can no longer be used if it is wet with rain, so the clay should be piled under the shed to avoid the rain after it is dug out. The process of making bricks is as follows: the clay blocks are broken up and the clay powder is left in a silo for 3 days.

Use a spiral mixer to mix the clay evenly, and at the same time let out the small air bubbles in the clay.

2. The next step is to soften the clay and put it into a mold to make long bricks, and then we cut the bricks into bricks according to the desired size.

3. Put the bricks in an environment of about 150 meters for drying to evaporate the water in the clay; It is then placed in a furnace and fired at a high temperature of about 950 °C. After cooling, the bricks are made.

1. Light capacity: The absolute dry capacity of lightweight bricks is only 500-700kg m*3, which is 1 4 of ordinary concrete and 1 3 of clay.

2. Thermal insulation and heat insulation: due to the manufacturing process of aerated concrete, tiny pores are formed inside, and these pores form an air layer in the material, which greatly improves the thermal insulation effect, so that the thermal conductivity of aerated concrete is 5 times that of clay bricks and 10 times that of ordinary concrete.

3. Sound absorption and sound insulation: The porous structure of aerated concrete makes it have good sound absorption and sound insulation performance, which can create a high airtightness indoor space for you. To provide you with a quiet and comfortable living environment.

4. Small shrinkage value: Due to the use of high-quality river sand and pulverized coal as siliceous materials, its shrinkage value is only, and the excellent materials with small shrinkage value ensure that your wall will not crack.

5. Impermeability: The pore structure of this product makes the capillary function poor, the water absorption and moisture conduction are slow, and the time required to absorb water to saturation in the same volume is 5 times that of clay bricks.

6. Environmental protection: no pollution in the process of manufacturing, transportation and use, protecting cultivated land, saving energy and reducing consumption, and is a green building material.

7. Earthquake resistance: The same building structure uses lightweight bricks to improve the seismic resistance level compared with clay bricks.

8. Durability: The long-term strength of aerated concrete is stable, and the strength is increased by 25% after one year of atmospheric exposure to the specimen, and it remains stable after ten years.

9. Machinability: This product is light in weight and has a variety of specifications and sizes, which is convenient for nailing, drilling, chopping, sawing, planing and laying pipelines, and using expansion pipes on the wall, which can directly fix hanging cabinets.

10. Fire resistance: the refractory degree is 700 degrees, which is a first-class refractory material, the fire resistance of 100mm thick blocks is up to 225 minutes, and the fire resistance of 200mm thick blocks is up to 480 minutes.

The bricks are made of clay by burning the trillions.

The soil used for burning bricks is commonly known as clay, which has good plasticity, and the excavated clay needs to be exposed to the wind and sun for up to half a year, and then decomposed and loosened by natural erosion, and then crushed and sieved by hand, leaving only fine pure soil. The pure soil is moistened with water to make a thick mud, which plays a vital role in the quality of the bricks. And the refined soil is molded by billet molding, and the bricks should be dried in the shade, and the bricks should not be exposed to the sun to make the bricks break out of the idea of cracks and deformation.

When the bricks are completely dry and fired in the kiln, the general bricks use coal as fuel, while the filter bricks with higher density are slowly burned with wheat straw, pine branches and other fuels. After dozens of days of firing, the green body is sintered. At this time, the fire is slowly extinguished, and the outside air enters the kiln, and the bricks are produced.

Types of bricks

The types of bricks include clay bricks, shale bricks, gangue bricks, fly ash bricks, lime sand bricks, concrete bricks, solid bricks, perforated bricks, unburned bricks, autoclaved bricks, etc. Clay bricks, also known as sintered bricks, are small artificial blocks used in construction, clay bricks are made of clay (including shale, gangue and other powders) as the main raw material, and are made of mud treatment, molding, drying and roasting, with solid and hollow differences.

Shale bricks refer to the use of shale and coal gangue as raw materials for high-temperature firing of bricks, including sintered shale porous bricks, shale hollow bricks, shale bricks, high thermal insulation modulus bricks, clear water wall bricks and other categories. It has the characteristics of high strength, heat preservation, heat insulation, sound insulation and so on.
