Preparation method of low-backpressure diesel engine tail gas particulate filter (DPF)
The invention discloses a preparation method of a low-back-pressure diesel engine tail gas particulate filter (DPF). The preparation method comprises the following steps: step 1, preparing materials; step 2, mixing; step 3, kneading: kneading the mixed raw materials to form pug; step 4, forming; step 5, drying; step 6, firing; step 7, porcelainizing: putting the green body into a kiln furnace, heating to 1400-1500 DEG C, firing, and porcelainizing the fired green body to form a cordierite finished product; 8, dust removal; according to the method, the aluminum oxide with the particle size of 12 +/-1 microns, D10 larger than or equal to 5 microns and D97 smaller than or equal to 25 microns is used for manufacturing the cordierite needed by the DPF product, the production process is simple, actual operation is convenient, large-scale production is easy to achieve, and the production efficiency of the product is improved.
本发明公开了一种低背压柴油机尾气颗粒捕集器(DPF)的制备方法，包括以下步骤：步骤一，配料；步骤二，混合；步骤三，捏合：将混合原料进行捏合，形成泥料；步骤四，成型；步骤五，干燥；步骤六，烧制；步骤七，瓷化：将胚体放置于窖炉中升温至1400～1500℃之间进行烧成，烧成后胚体进行瓷化形成堇青石成品；步骤八，除尘；步骤九，检查，本发明利用粒径为12±1um、D10≥5um，D97≤25um的氧化铝制造DPF产品所需的堇青石，生产过程简单，实际操作方便，容易实现大规模生产，提高了产品的生产效率。
