Problems solved by technology

Although the non-fired brick process can solve the problem of controlling the generation of smoke from the source, the selection of raw materials for brick-making is limited by the non-fired process, and the performance of the bricks produced is far from the level of fired bricks. Therefore, The application of non-fired bricks is also limited, and it is not suitable for large-scale promotion and application
Based on this, most of the existing brick and tile factories still use the traditional "blank-drying-roasting" process to produce standard bricks, and at the same time cooperate with the smoke and dust treatment system to control the emission of solid particle pollutants, and the pressure on environmental protection and economic pressure is huge.

Embodiment 1-3

[0047] Embodiment 1-3 all relates to a kind of standard brick preparation process, and concrete process step is as follows:

[0048] 1. Preparation of brick mixture

[0049] ⑴ Crushing of cinder, dry sludge and construction waste

[0050]First, crush cinders, dry sludge and construction waste, wherein the dry sludge is obtained from sewage treatment sludge after roasting at 500°C and cooling down. Construction waste can be waste concrete, waste mortar or a mixture of the two. Examples 1-3 All of them are waste concrete.

[0051] The crushing is divided into two stages. First, the jaw crusher is used for crushing, and the particle size after crushing is controlled at ≤20mm; then it is sent to the high-speed crusher for the second crushing, and after fine crushing, it passes through a 14-mesh sieve, and the particle size is controlled at ≤1.5mm .

[0052] ⑵ Mixing of raw materials

[0053] Weighing the crushed cinder, dry sludge and waste concrete according to the ratio, sen...

Embodiment 4-6

[0083] Embodiments 4-6 all relate to a standard brick preparation process, and are all based on Embodiment 2. The difference from Embodiment 2 is only in the specific process operation of the "spraying treatment liquid-drying" step, which is as follows:

[0084] Spray evenly the surface treatment solution accounting for 1-5wt% of the mass of the brick on the surface of the brick, and then send the brick to the drying room for drying at 70-90°C; again evenly spray the surface treatment of 1-2wt% on the surface of the brick liquid, and then dried at 70-90°C to obtain dried bricks.

[0085] The same surface treatment fluid was used for the two sprays. Specifically, the formula and spraying amount of the spray treatment liquid used in Examples 4-6 are shown in Table 3.

[0086] Table 3. Spray treatment liquid component distribution ratio and spray treatment liquid spray amount table in embodiment 4-6

[0087]

[0088] The inorganic mineral powder in Table 3 is made by mixing ...

Embodiment 7-10

[0091] Examples 7-8 all relate to a standard brick preparation process, all of which are based on Example 2, and differ from Example 2 only in that the raw material formula of the standard bricks is different, see Table 4 for details.

[0092] Examples 9-10 all relate to a standard brick preparation process, all of which are based on Example 5, and differ from Example 5 only in that the raw material formula of the standard bricks is different, see Table 4 for details.

[0093] Table 4. Standard brick raw material matching table in embodiment 7-10

[0094]

[0095] The glass fiber powders used in Examples 7-10 were all purchased from Sarn Chemical Technology (Shanghai) Co., Ltd., with a specification of 9-13 μM.

Abstract

The invention relates to a standard brick preparation process and a standard brick, and relates to the field of building bricks and preparation thereof. The process includes the steps of: 1. making agreen brick; 2, spraying a surface treatment liquid I accounting for 1-5wt% of the mass of the green brick to the surface of the green brick; wherein the surface treatment liquid I is prepared from the following components by mass percentage: A. 5-8% of inorganic mineral powder with a particle size of less than or equal to 1.5mm, B. 3-5% of a water-soluble polymer, C. 1.5-3.0% of fumed silica, andD. the balance water; the inorganic mineral powder is a mixture of nano aluminum oxide, cryolite powder and mica powder; and the water-soluble polymer is a mixture of polyvinyl alcohol and water-soluble chitosan; 3. under the condition of 70-90DEG C, drying the green brick sprayed with the treatment liquid I; and 4, performing roasting. The standard brick preparation process provided by the invention has the advantages that the content of solid particles in the brick making waste gas can be effectively reduced and the emission of solid particles is reduced from the source, and the prepared standard brick has the advantages of excellent physical and mechanical properties and good permeation resistance.

Description

technical field [0001] The invention relates to the technical field of building bricks and their preparation, in particular to a preparation process of standard bricks and standard bricks. Background technique [0002] The artificial drying of brick and tile enterprises and the discharge of particulate matter from roasting kilns are one of the man-made sources of particulate matter in the polluted atmosphere. Due to environmental protection requirements, the emission standards for air pollutants in the brick and tile industry are becoming increasingly strict. Taking the national standard "Emission Standard of Air Pollutants for Brick and Tile Industry" GB29630-2013 promulgated in 2013 and implemented in 2014 as an example, it clearly stipulates that the maximum allowable particulate matter in exhaust gas discharged into the atmosphere is 30mg / m 3 (The special emission limit in key areas is 20mg / m 3 ). [0003] For such a strict air pollution particle emission limit, brick...
