How much does water reducing agent equipment cost? Lets come look

With the continuous development of the construction industry, many places require not only construction but also renovation. Therefore, the demand for water-reducing agents, one of the key processing raw materials, is very large, and the profits of water-reducing agents are also good. So how much does water-reducing agent equipment cost? Many people who have begun to pay attention to this industry don’t know much about it.

Due to the high efficiency and low dosage of high-performance water-reducing admixtures, their sensitivity to raw materials and environmental conditions is greatly increased. Therefore, on-site technical support for this type of products is very important. For the construction party: due to differences in the selection, formula, synthesis process, additives, quality control, compounding technology, etc. of water-reducing agent production raw materials from different companies, the performance, quality and stability of the high-performance water-reducing agent products produced They are not the same, so product after-sales service is particularly important to the construction company.

How much does water-reducing agent equipment cost?

1. Water-reducing agent synthesis equipment generally requires: naphthalene melting tank, centrifugal pump; sulfuric acid storage tank, formaldehyde storage tank; liquid alkali storage tank; Enamel reactor; neutralization tank with stirring; storage tank; powder making also requires spray drying equipment, etc. There are many types of water-reducing agents, including naphthalene-based water-reducing agents, carboxylic acid water-reducing agents, aliphatic water-reducing agents, etc.

2. In addition, there are many operating specifications of water-reducing agent equipment, such as 10 vertical positions, 15 vertical positions, 20 vertical positions, 30 vertical positions, 1 vertical position, 2 vertical positions, etc. Therefore, the price of purchasing water-reducing agent equipment ranges from 40,000 yuan to 100,000 yuan.

3. At present, modern concrete mixing stations must be equipped with high-performance pumping concrete. Without concrete admixtures, that is, water-reducing agents, various troubles may occur. In addition to water reducing agents, there are also retarders, air entraining agents, etc., which can affect safety issues such as slump.

On-site technical support for product after-sales should be organically combined with the compounding process. The raw materials and compounding formulas used in compounding are not subjectively imagined by technicians. The specific process is based on the preliminary compounding formula. , after on-site trial preparation, improved compound formula, on-site trial preparation, and then improved compound formula, repeated many times until the compound product fully meets the on-site construction requirements. Specifically, during the on-site trial preparation process, the following issues will be mainly involved:

(1) The test shows that the fluidity test results of certain cement varieties have little correlation with their concrete, and sometimes even appear completely different. Opposite test results. Therefore, it is not enough to do a pure slurry test, and further concrete tests should be done to confirm. Compared with pure mortar, the test results of mortar water reduction rate are consistent with its concrete.

(2) Regardless of the trial mixing or preparation of concrete, the air content of concrete cannot be applied to the air content of naphthalene series concrete. When high-performance water-reducing agent concrete has a higher air content (4% to 5% ) is safe to use, and the strength of the concrete will not decline in the later stage. However, if the naphthalene series gas content is high, the strength of the concrete will decrease in the later stage. At the same time, attention should also be paid to the stability of the air content of high-performance water-reducing agent concrete.

(3) The mix ratio of high-performance water-reducing agent concrete is the key factor affecting the performance of concrete. The benchmark concrete mix ratio used in the test has little correlation with the mix ratio used on the construction site, because the cement selected for the project is quite different from the benchmark cement, and the engineering concrete also contains a large amount of mineral admixtures.

(4) Since the variety and quality of cement in my country are generally complex and changeable, with significant differences, especially when encountering cement with extremely poor compatibility, water-reducing agent concrete may still suffer from mixing logistics Poor mobility and large slump loss of concrete.

　(5) When preparing concrete with water-reducing agent, the measurement should be carried out strictly in accordance with the optimal dosage and water consumption after trial preparation, and the measurement equipment and measurement accuracy must be accurate and sensitive. Otherwise, when the amount of high-efficiency superplasticizer is exceeded, adverse phenomena such as segregation, bleeding, hardening or excessive air content will occur.

(6) When the cement fineness is large, the mud content of sand and gravel, the stone powder content, and the needle flake content are large, it will have an adverse effect on the performance of high-performance water-reducing agent concrete and should be taken seriously. If the conditions are good, you can use a stone washing machine to clean the stones. In addition, sand rate, gradation, particle shape, texture, etc. also have a certain impact on it and cannot be ignored. </p
