Product description
Sk34 firebrick have good fire resistance: clay firebricks have good high temperature resistance, usually can withstand high temperatures above 1000℃, and some can even reach high temperatures above 1500℃
Advantages of sk34 firebrick
Sk34 firebrick have strong corrosion resistance: clay and kaolin in clay refractory brick materials contain high silicate and aluminate, which can resist various acids, alkali, salt and other chemical corrosion, so it is widely used in chemical industry, metallurgy, electric power and other fields..
Sk34 firebrick have good thermal insulation performance: clay firebrick often contains some thermal insulation materials, such as expanded perlite, expanded vermiculite, etc. These materials can improve the thermal insulation performance of clay firebrick, so that it has excellent thermal insulation performance in high temperature environment.
