Jiangdu acid refractory castable refractory castable professional wholesale supplier

Acid-resistant refractory castable is resistant to acid medium degree 800-1200 (nitric acid, etc.,,) said corrosive acid castable refractory castable refractories. It is based on water glass as binding agents, acidic or semi-acidic refractory as an aggregate and powder, plus a small amount of coagulant preparation. But do not refractory castable acid and alkali, hot phosphoric acid, and high fatty acid corrosion. Acid formulated refractory castable abundant sources of raw materials, low prices, so in metallurgy, chemical, petroleum, light industry and other sectors have been widely used in thermal equipment. General Ingredients acid refractory castable composition: acid refractory aggregate 60% -70%, 30% -40% powder, plus sodium silicate solution density 1.38g / cm3 of 13% -16%, with fluorine as sodium When the coagulant is added in an amount of 10% -12% by mass of sodium silicate solution. Combined water glass pouring acid refractory aggregate and powder acid acid resistance of related materials and their uses. Configuring acid refractory castable aggregate mainly silica, cast stone, alabaster, andesite, diabase. Several of raw materials into the acid degree (measured by weight method,%) as follows: cast stone 98%, greater than 97 percent silica, clay clinker 92% to 97%, 92 to 96 percent wax stone, andesite more than 94%. Selection of the raw materials in accordance with conditions of use. However, care must be taken when using silica quartz polycrystalline change when heated, the transition process will produce a volume change (expansion), it is preferable to use the waste material to replace part of silica brick materials as aggregate, configure this castable powder mainly silica powder 'cast stone, porcelain powder, high-silica clay clinker powder, which casting powder is used more acid powder. Acid-resistant refractory castable is mainly used for anti-corrosion of the flue and chimney lining, acid storage tank, pickling tank lining, pus nitrate reduction tower lining, acid recovery furnace linings and other high-temperature gas within the container by acidic corrosion lining.
