Product details
Introduction
GPF (Gasoline Particulate Filter) gasoline engine particulate filter is evolved from a flow-through three-way catalyst. It is a ceramic filter installed in the gasoline engine exhaust system. The appearance is generally cylindrical.
Feature
Thin pore wall
High compressive strength
Good thermal shock resistance

Working principle
GPF uses wall-flow honeycomb ceramics as the carrier. There are many parallel axial honeycomb channels in the carrier body. One of the two adjacent channels has only the inlet open, and the other has only the outlet. Exhaust gas flows in from the open inlet channels and exits through the porous walls of the GPF carrier to adjacent channels.
PM particles are trapped in and on the wall of the carrier by means of interception, collision, diffusion, and gravity sedimentation, so as to capture particulate emissions before they enter the atmosphere.
Application
GPF ceramic honeycomb carrier, coated with catalyst, is used in the catalytic converter of gasoline vehicle exhaust gas purification treatment, to catalytically convert and purify the harmful substances in the exhaust gas of automobiles, and meet the requirements of emission regulations.
Production process
(1) Inspection, screening and preparation of raw materials;
(2) After mixing the powder materials evenly, add additives for kneading, roughing, primary aging, refining and secondary aging and then sieving;
(3) The sieved mud is extruded into an extruder to obtain a green honeycomb ceramic carrier;
(4) The green body is subjected to microwave drying and shaping, deep drying and hot air deep drying in sequence;
(5) The dried carrier is cut and fired to obtain a cordierite honeycomb ceramic carrier;
(6) The obtained cordierite honeycomb ceramic carrier was trimmed and edged to obtain the final product.
Quality control
1. Production is strictly in accordance with IATF16949 and IS09001 quality management system.
2. Incoming material inspection.
3. Sampling inspection in the production process.
4. Sampling inspection records before delivery.
