FIELD: chemistry. ^ SUBSTANCE: present invention pertains to the method of depositing a suspension coating onto a carrier. The invention particularly relates to the method and device for coating catalyst carriers, for example, carriers of automobile catalytic converters. Description is given of a device which implements the method of coating a carrier with open pores with at least, one suspension coating. The coating contains solid substances and substances dissolved in a liquid medium, the amount of which, in wet conditions, always exceeds the required amount of coating and fluctuates from one carrier to another. Excess suspension is removed from carrier channels by pre-extraction. The difference between the actual amount of suspension deposited on the carrier and the given required amount of coating is then determined and that difference is reduced through repeated extraction of wet suspension. After stages (a) and (b), the coating deposited on the carrier is dried and burned. ^ EFFECT: perfection of the method of coating a carrier and design of the coating device. ^ 8 cl, 2 dwg |
