Описание продукта

Laurel supply several grades of insulating brick for use in applications from 1260℃ to 1550℃.Each grade of brick is formulated to meet specific thermal and physical requirements. После обжига каждый кирпич подвергается механической обработке с соблюдением допусков по размерам.. Insulating bricks are manufactured utilising exceptionally high purity clays and other ceramic materials.The carefully graded organics which are used during the manufacturing process burn out during firing to give a uniform pore structure.

Функции

1.High insulating properties 2.Strong compressive strength 3.Low heat storage 4.High purity 5.Tight dimensional tolerance 6.Energy saving
