Acid resistant castables are not only plastic, but in many amorphous refractory materials, the production process of acid resistant castables is relatively simple. It can be produced without special equipment, and the degree of mechanization is high. It is simple to ensure that the quality is in uniform standards, so quality reliability Strong.
Since it can be directly used in engineering without special treatment, the construction is simple and does not require too much preparatory process. However, it is required that the acid-proof castable has a slightly poor anti-penetration function, so it should be laid a layer of waterproof before use. Excellent primer and then the construction of acid-resistant castables.
What is the Effect of Acid Resistant Refractory Castables?
Used as anti-corrosion flue and chimney lining, acid storage tank, pickling tank lining, nitric acid puncture tower lining, acid recovery furnace lining and other container linings corroded by acidic high temperature gas.
Acid resistant castables are widely used in industrial furnaces such as metallurgical occupation, petroleum, chemical, building materials, electric power and machinery industries. Compared with other amorphous castables, the acid resistant castables have better fluidity, making it easier to construct and simpler. The construction results of the ambition are reached, and at the same time, due to the high binder and moisture, the fire retardant is also outstanding, so the acid-resistant castable also has excellent high temperature resistance.
Acid Resistant Refractory Castables Product Material Ratio
The general composition of the acid-resistant castable is: 60%-70% of acid-resistant refractory aggregate, 30%-40% of powder, and 13%-16% of water glass solution with density of 1.38-1.42g/cm3, with fluorosilicic acid. When sodium is used as a hardening agent, the amount of participation is 10%-12% of the mass of the water glass solution.
Acid Resistant Refractory Castables Product Advantages
With regard to the use of acid-resistant castables, it can be useful to save on power, and often only requires boring and baking during the process of operation.
Then, after using the acid-resistant castable, it can make its production power higher. Because of the process of manufacturing it, its process is relatively simple, and its production power is several times that of ordinary fire-resistant brick.
Because of its existence, it is often possible to make its construction power progress in the process of construction, and it can be arbitrarily shaped.
At the time of manufacture, the acid-resistant refractory castables are mainly made of aluminate, high alumina, siliceous materials, and other unshaped refractories made of admixtures and binders; they have strong compressive strength and acid corrosion resistance. High, low water absorption and low heat preservation characteristics, chic construction of ambition material, simple construction, good workability, strong adhesion, long time of initial setting and operation, long term strength increase, strong impermeability, no acidification required. It is easy to ensure the compactness and fullness of the masonry ash joints, and can significantly improve the airtightness, integrity and corrosion resistance of the lining of the chimney.
