Under the inspection methods and inspection conditions specified in this standard, A110 series (A110-1, A110-2, A110-3, 2113-1) are suitable for the following types of products: 1110-6) The product quality of the strong synthesis catalyst is recorded in terms of activity (volume percentage content at the reactor outlet), which is a technical indicator of the slight decline in the tax rate. Table 3 Index name (volume percentage content of ammonia at the outlet), % 4 Test method Technical index Heat-resistant front The activity, main physical properties and chemical composition of the A110 series ammonia synthesis catalyst are tested in accordance with ZBG 74002. 5 Inspection specification ZB G 75010-90
51 The quality of the products shall be inspected by the metrology inspection department of the manufacturer. Products are not allowed to leave the factory without inspection. Each batch of products leaving the factory shall have a product qualification certificate. Products are inspected in batches, and the representative quantity of the short batch shall not exceed 50t. How to sample the product: the inspection department will randomly sample the number of units according to the cubic root of the number of product packaging barrels, that is, ×. If the number is not large, the number of sampling units shall be increased to a larger number and shall not be less than 10. The total number of samples is 3: After separation, they are divided into mixed, prepared and excessive samples. The samples will be marked with the product name in the sealed bags. The samples will be accepted by the inspection station, and the sample number, etc., and the sample can be kept for one year for verification. When the product is not qualified, the inspection packing limit should be adjusted. 、The official chemical trial tube is registered and calibrated according to the light, inspection and fine shadow. If the label does not contain the sample, the batch of products is still determined to be unqualified.
The party who hired the insurance company has the right to reuse the product according to the inspection method shown in the label. If necessary, please contact the relevant Huaxin for quality assurance.
New logo and packaging Hanyou ili
6A1I0 series ammonia synthesis catalyst products should be packed in a sealed iron tree: Pay attention to the packaging, and be accompanied by a product quality certificate. The certificate should include: product name, model, label number, batch number, particle size, net weight, manufacturer name and other contents.
62 The packaging barrel is black and has obvious and firm markings. The contents include: manufacturer name, product name, model, batch number, particle size, net weight (kg), trademark and national standard GB-191 6.3 The packaged products should be stored in dry warehouses to prevent pollution and moisture. 6.4 It is strictly forbidden to drop and bump during transportation and loading and unloading. There should be protective facilities during transportation.
