During the drying process of sintered brick after absorbing water, the soluble salt content in the product will be brought to the product surface, forming the phenomenon commonly known as "whitening" or "alkali bleeding", which is the frost phenomenon of sintered brick. In order to ensure the construction quality of each construction unit, the following is a brief introduction to the frosting problem of sintered bricks: how to deal with the frosting phenomenon of sintered bricks: the frosted sintered bricks should be washed with water once a day, after a period of time, it will be better, and there is no need to deal with it again. Generally, brick masonry will appear. Four problems should be paid attention to in brick masonry: 1. Before bricklaying, the fired bricks must be watered; 2. The sand used for bricklaying shall be clean, saline and alkaline (white

The quality inspection of landscape fired brick is very important, which is related to the survival of enterprises. To do a good job in quality inspection is the key link that every enterprise must do well. For landscape fired brick, quality inspection is to check the performance defects of the product, mainly including strength, gauge difference, deformation, crack, corner drop, pitting, whitening, frosting, diagonal inequality, etc. The means adopted are mainly listening, watching, measuring and inspecting. Listen: Take two bricks of the same batch (same manufacturer) and knock them. If the sound is "puffing" or "all through" and very dull, it means that the strength of the bricks is not good; If the sound is "bang bang", it has a very clear porcelain texture

You may be familiar with sintered bricks, but you may not know the shale sintered bricks. Today, I will tell you about the use of shale materials. 1. Cultural fired brick is a classic material to express the style of classical culture. The natural color difference produced when it is calcined gives people a feeling of soft beauty. Therefore, each rock brick contains a new cultural concept that combines ancient civilization with modern science and technology. 2. The main components of environmental protection are mainly weathered rocks with pottery as a supplement, which are taken from all parts of the country. Rock and soil of different colors are burned into rock and soil bricks of different colors by modern technology. Thousand degrees

Sintered square brick is made from crushed shale by mixing, homogenizing, vacuum extrusion or pressing, waste heat drying and high-temperature sintering. The introduction of advantageous sintered brick technology, equipment and computer control system from Germany and the production of popular sintered bricks in Europe and the United States have filled the gap in the domestic market. The uniqueness of the product mainly includes the following points: 1. Sintered bricks are sintered products. High strength ≥ 40 mpa, excellent frost resistance, durability and weather resistance. The color is durable. 2. The "eight side chamfer" is suitable for the laying of various patterns * European and American popular style. 3. "Double rough surface

The strength of sintered brick is the concern of major construction units, and there are many technical measures to improve the strength of sintered brick. Here are a few simple introductions: 1. Improve the forming pressure of brick machine. Increase the forming pressure of brick machine to increase the density of bricks. Only increase the density of brick. Only by increasing the density of brick blanks can we burn high degree sintered bricks. Practice has proved that the compressive strength of fired brick is generally (13.9~15) MPa for brick blanks with forming pressure of (2.2~2.3) MPa, while the compressive strength of fired brick blanks with forming pressure of 3 MPa can easily reach 20 MPa. 2. Properly improve sintered brick

Shale full body brick has strong practicability and is widely used as ground paving and masonry materials. The main thing is that it is very practical and unique, which is not found in any other brick. Advanced scientific formula is used to add mixed raw materials in a certain proportion, so that particle size, temperature and mixing degree can be enhanced with advanced equipment and technology to achieve a better plastic state, After extrusion, the brick is hardened. The shorter the time is, the better the effect will be. The brick has good practicability and neat appearance. Here are a few points. 1. The surface of anti-skid shale brick is smooth and clean, but its moderately rough surface is enough to get up in rainy days

Although we often meet with each other in daily life, there are not many opportunities to buy sintered bricks. In fact, we still go through many detours when we actually buy sintered bricks. Some friends even buy ordinary sintered bricks at a high price. For our inexperienced friends, if they want to buy real things, today I will tell you some tips on purchasing. 1. Pick up two bricks and knock each other. If they make a clear sound, it means that the quality is good, and the hardness and density are relatively high. On the contrary, making any other sound is not as good as the previous one. 2. Take out a brick and drop a drop of water to measure its content

Disadvantages of cement tile: non slip, non compression resistance, easy to break, easy to fade, poor toughness, non alkali resistance, acid resistance, easy to weathering, poor freeze-thaw performance, high repair rate; Advantages: low cost. Disadvantages of marble floor tile: non slip, non compression, easy to break, poor toughness, strong radiation, high cost; Advantages: smooth and bright, it is a high-grade but not ideal floor decoration material in the domestic market. The unique quick drying performance of sintered brick makes its anti-skid performance good. The brick body is sintered at 1100 ℃, and the internal particles are melted, which greatly improves the wear resistance. There is no dust generated after rolling by vehicles, which will not pollute the environment

Introduction: sintered brick is also an indispensable important material in our construction. Bricks for building load-bearing and non load-bearing walls, which are made of clay, shale, coal gangue or fly ash through molding and high-temperature roasting, are collectively referred to as sintered bricks. 1、 Raw materials for making sintered bricks: the main raw materials of ordinary clay bricks are silty or sandy clay, whose main chemical components are SiO2, Al2O3, Fe2O3 and crystal water. Due to different geological generation conditions, it may also contain a small amount of alkali metals and alkaline earth metal oxides. The production process of clay brick mainly includes taking soil, refining mud, making bricks
