(4) setting the test duration is 2min;
(5) open pressurized air part flow arrangement, air diverter purges integer catalyzer automatically;
(6) purge after 2min, equipment is closed automatically, stops purging;
(6) take off the integer catalyzer of test, weigh the weight 518.21g of catalyzer;
(7) 1 calculate the coating fastness of integer catalyzer as follows
Formula 1: coating fastness (expulsion rate/%)=(520.4-518.21) * 100/520.4=0.42
The coating fastness (coating shedding rate) of the catalyzer of measuring is 0.42%, and the coating fastness of this catalyzer is better, can under the impact of vehicle exhaust, be attached to securely on ceramic monolith.
