Acid Resistant Castables Definition
 
The acid resistant castable is made up of 60%~70% of acid-resistant aggregate, 30%~40% of powder, and 13%-16% of sodium silicate solution with density of 1.38~1.42g/cm3. When the agent is added, the amount of the refractory material which is 10% to 12% of the mass of the sodium silicate solution and which is resistant to the corrosion of the acidic medium at 800 to 1200 ° C is called an acid-resistant castable. Acid resistant castable is made up of liquid instant powdered sodium silicate as binder, acid or plate acid refractory as aggregate and powder, and a small amount of accelerator.Acid castables are not resistant to alkali, hot phosphoric acid and high fat.

Acid Resistance Castable Feature
 
1.Acid Resistant Castable Have Energy Saving.
 
Eliminating the high-energy calcination process, only molding, drying and baking are required, and the energy consumption is 5 to 6% of the fired refractory bricks.
 
2.Acid Resistant Castable Have High Productivity.
 
The refractory castable is simple in production process and its production efficiency is 4~9 times that of refractory bricks.
 
3.The Construction Efficiency is High.
 
The construction efficiency of unshaped refractory materials is 6~15 times that of bricklaying.
Can be freely shaped.
 
Acid resistant castable can be made into a whole-kind lining and can be used to quickly repair the kiln to improve its life and operation rate.
 
4.Suitable for all kinds of Kiln Projects.
 
The use of special high-quality materials can be used to arrange masonry materials with good resistance to heat and earthquake resistance to harmful gases and slag erosion, flaking and heat insulation.

Acid Resistance Castable Application
 
1. Acid resistant castables are mainly used in metallurgical industrial furnaces and are also widely used in kiln and thermal equipment in petroleum, chemical, building materials, power and machinery industries.
 
2. Acid resistant castables can be widely used in various heating furnaces and other non-slag, acid-free corrosion-free thermal equipment.
 
3. Acid resistant castables is exposed to hot metal, molten steel and molten slag and has a high working temperature. Such as tapping trough, Shenggang trough and blast furnace body, tapping ditch, etc.
 
 
Acid Resistant Castables Technical Performance
 
1.The acid resistant castable has stable performance in various concentrations of organic and inorganic acids, especially in dilute acid, industrial water and neutral aqueous solution, castable acid resistant has high impermeability.
 
2.The acid resistant castable has good heat resistance, lining in titanium dioxide rotary kiln, the use temperature up to 950 ℃ - 1000 ℃.
 
3.Acid-proof castables use non-toxic curing agent, non-toxic to the operation and construction personnel, identified by the medical and health departments, can be used in food, medicine and other equipment anti-corrosion engineering.
 
4.Acid resistant castables are cheaper than organic acid-resistant materials. In addition to its organic and acid-resistant corrosion resistance, refractory castable acid resistant also has the unique properties of resistance to strong oxidizing media corrosion.
 
5.Castable acid resistant room temperature curing, simple construction, easy to use, easy to transport, moisture-proof storage.
 
Acid Resistant Castables Use Precautions
 
1.Acid resistant castables should not be used alone in particularly humid environments. Because the refractory castable acid resistant has excellent fire resistance but refractory castable acid resistant poor penetration resistance,acid-proof castable is not suitable for use in humid environments. If acid proof castable is necessary to use it, acid proof castable is necessary to lay a layer of waterproof material before use.
 
2.Acid proof castable is best not to use it as a separate refractory material. Acid-resistant castables have excellent fire resistance, but they are likely to break the bond of acid-resistant castables when used directly in high-temperature environments because of their own characteristics. Therefore, there should be a layer of insulating felt when used as a refractory.
 
3.Acid resistance refractory castable can not be used in an environment where the temperature difference is too large in a short time. We know that acid-resistant castables are similar in characteristics to cement materials and require a certain amount of time to solidify.
 
 Acid Resistant Castables Precautions for Storage
 
Acid resistant castables must be stored in a strict classification in the warehouse. Acid resistant castable is strictly forbidden to be placed in the open air, where it is blown by the wind, sunshine, and rain
 
 Acid Resistant Castables Other Precautions
 
The castables produced by Rongsheng Acid-Resistant Castings are mainly used in anti-corrosion flue and chimney lining, acid storage tanks, pickling tank linings, acid recovery furnace linings and other container linings which are corroded by acidic high temperature gases. Rongsheng refractory castables remind users that acid-resistant refractory castables are generally used for anti-corrosion.Acid proof castable is not the same as ordinary refractory castables, so acid-proof castable is best not to use acid-resistant castables as refractory castables. The fire resistance is not comparable to refractory castables, the main role is acid and corrosion resistance.
 
The acid resistant castable material is flexible and can be used as an amorphous refractory material. Castable acid resistant can also be used to make various irregular preforms. It is a versatile refractory product, but it also has the maximum performance of acid-resistant castables. It can be used reasonably. The acid-proof castable should be used in an environment with short time and large temperature difference during the use, and it should not be used in a humid environment, and the acid-resistant castable can not be used under high temperature. Destroy its performance, thereby reducing the temperature of the acid-resistant castable.
