1, 1050: Classification temperature, also called classification temperature.
According to GB/T17911-2006, the change of the heating permanent line of the refractory ceramic fiber product is determined, and the temperature at which the heating wire shrinks does not exceed the specified value is the classification temperature.
For soft products such as refractory ceramic fiber blankets, the heating line shrinks by no more than 4%.
It means that the ceramic fiber blanket has a line shrinkage of less than 4% during the heating time of 1050 ° C.
2, ordinary: ceramic fiber blanket material classification, according to the working temperature from low to high is divided into ordinary, standard, high purity, high aluminum, zirconium aluminum, containing zirconium 6 grades.
The common ceramic fiber blanket corresponds to an operating temperature of 1050 ° C.
The ceramic fiber blanket is made of high-temperature melting silk, such as pure inorganic material, such as aluminum silicate, or by blowing or collecting cotton.
