In order to ensure that acid refractories are environmentally friendly, Kerui chooses harmless and renewable raw materials for production. In addition, Kerui takes into account the impact of each link on the environment and constantly evaluates it. Another reason why customers can buy with confidence is that Kerui acid refractories have international environmental management system certifications.
We can know from the name that acid refractories are used in environments with strong acid corrosion. When encountering various concentrations of organic acids or inorganic acids, acid resistant castable can always maintain stable performance. Especially when encountering dilute acid, industrial water, and neutral aqueous solution, the application of acid refractories will not produce crystal salts and has high impermeability.
When water is added and solidified, the mechanical strength of acid resistant castable is amazing. After testing by Kerui laboratory, the cured acid-resistant castable has excellent compression and bending resistance. In addition, acid refractories also have adhesive properties that cannot be ignored. The bonding strength of fire brick, masonry plates and acid resistant castable is great.
Acid resistant castable are suitable for high-temperature kilns with operating temperatures of about 950°C-1250°C (1742℉ to 2282℉). If you want to enhance the refractoriness of acid resistant castable, you can contact Kerui to modify the chemical composition during production or add other high-temperature-resistant products during use. For an accurate and effective solution, you can contact Kerui now.
The raw materials for configuring acid resistant castable are abundant and cheap, which also creates preferential acid resistant castable prices. If you want to achieve better protection in acid kiln, then acid resistant castable is the choice with the highest economic value. Especially when you consider buying refractories in bulk, Kerui will provide ex-factory acid resistance castable price.
The acid proof castable have the advantage of being easy to use. Just addding proper amount of water is and the curing effect is excellent. The curing of acid refractories has relatively low temperature requirements, and a good curing effect can be achieved at room temperature. Due to the simple operation, the construction efficiency will be improved accordingly. Kerui provides professional construction manuals.
The chimney is the place where various thermal equipment and kilns discharge gas. Acid proof castable is essential in chimney with silica fire brick. Because this product has strong plasticity, it is not limited to the shape and position of the chimney. Similar applications include flue ducts for acidic atmospheres, linings for nitric acid concentration towers, acidic containers, and so on.
Due to the fast curing time and excellent compressive strength, acidic refractories are ideal for kiln or other engineering repairs. During the operation of the kiln, it is inevitable that damage will occur. The main cause of damage may be chemical attack.Reasonable use of acidic refractories includes damaged parts of kilns, repairs of special buildings, etc.
The acid resistant castables can be used in various industrial sectors, including petroleum, chemical, metallurgy, electric power, pesticides, food, fermentation, hydrolysis, pickling, etc. The general parts suitable for this product include reaction kettles, storage tanks, tower pools, floors, trenches, electrolyzers and other anti-corrosion projects.
The manufacturing process of Kerui acid resistant castable roughly includes batching, molding, drying and baking. The energy-intensive sintering process is eliminated, and the energy consumption of the entire production process is only 5%-6% of that of other dense or soft refractory brick. This also results in lower production costs and lower product prices.
The production process of acid resistant castables is relatively simple. The production efficiency is 4-9 times that of refractory bricks. When you confirm the demand, the Kerui factory will immediately prepare for production and delivery for you. Compared with other types of refractory products, the production cycle of acid resistant castables is the shortest.
Kerui acid proof castable has lower requirements on the type of construction furnace. No matter what type or shape the furnace is, customers can use this product freely. What’s more, you can make acid resistant castables into precast blocks and use pre-cast blocks directly. The acidic refractories are ideal for quickly repairing and increasing service life. Here is more information on Kerui VK.
No matter Kerui acid resistant castable or its production process, it has ISO, SGS, CE and many other international certificates. These certificates confirm the quality, safety and reliability of Kerui castable. Therefore, customers can buy with strong confidence.
Kerui’s ability to provide responsible service is an important reason why we stand out in the market. The international business manager will follow up your order throughout the process and update you on the production and delivery status in time. Besides, Kerui supports customized service.
More than 20 experienced engineers provide timely and professional technical support to customers. From product selection to usage, kiln maintenance, etc., engineers provide all-round technical guidance. Today, Kerui supports online and offline guidance to efficiently solve problems for customers.
