Harbin Municipal Market Supervision Bureau sampled seven products such as benzene plates and plastic pipes

recently, Harbin Municipal Market Supervision Bureau issued a "notice on the quality supervision and spot check of seven products such as benzene plates and plastic pipes (shapes)", which said that in the second quarter of 2017, the Municipal Bureau, in accordance with the relevant arrangements of the "Harbin 2017 annual product quality supervision and spot check plan", conducted a survey of benzene plates, wires and cables Seven kinds of products, such as plastic pipes (types) and toilet paper (towels), have carried out product quality supervision and random inspection

a total of 20 batches of plastic pipe (profile) products from 13 manufacturing enterprises in Harbin were randomly selected, and 19 batches were qualified. The unqualified item of the product causing the unqualified problem is that the wall thickness does not meet the standard requirements. National standard gb/5836 The specified minimum wall thickness is ≥ 2.0 mm, while the measured value is only 1.7 mm. The reason for the unqualified products is that the enterprise sells them in pieces during the sales process. In the production process, the main reason for the unqualified wall thickness of pipes is to deliberately thin the pipes in order to increase the number of pieces per ton of raw materials

a total of 50 batches of plastic steel window products from 31 manufacturing enterprises in Harbin were randomly selected, and 48 batches were qualified, with a batch qualification rate of 96%. According to the supervision and random inspection, the unqualified items of unqualified products are mainly the wall thickness of visible surface and the wall thickness of reinforced steel, which do not meet the standard requirements. Unqualified profile wall thickness is easy to cause fillet cracking and decline in the impact resistance of plastic profiles, which is easy to cause unqualified drop hammer impact performance and tensile impact strength. After being impacted by external forces, it is easy to crack and deform, which will seriously affect the overall performance of doors and windows. The unqualified wall thickness of reinforced steel is easy to cause the warpage and deformation of doors and windows in the process of use, and the physical properties of wind pressure resistance, rain resistance, air tightness, thermal insulation and so on will also be seriously reduced

a total of 28 batches of wire and cable products produced by 12 enterprises in the jurisdiction of Harbin were randomly selected, and 28 batches passed the inspection. According to the results of the random inspection, the production enterprises of the products inspected pay more attention to the product quality, the production systems are relatively sound and perfect, the raw materials and production processes are strictly controlled, and the product quality is relatively stable. Experts remind that according to the spot check in recent years, there are still certain quality risks in wire and cable products. It is mainly caused by the weak quality awareness of individual enterprises, the reduction of production costs in order to obtain economic benefits, the failure to organize production according to the process, the illegal use of copper conductors whose cross-sectional area of conductors does not meet the standard requirements, and even the use of recycled copper containing impurities, which is prone to overheating and even fire hazards in the process of use

a total of 20 batches of toilet paper (towels) products produced by 11 enterprises in the jurisdiction of Harbin were spot checked, and 18 batches were qualified. According to the supervision and random inspection, the unqualified products are mainly due to the obvious dead fold defects and damage on the paper surface and the implementation of standard errors. The main reasons for the unqualified items are as follows: first, the raw material pulp of papermaking is not qualified, the pulp fiber structure is too short, and the distribution is uneven. A certain amount of recycled paper is added, resulting in the decline of paper tensile capacity; Second, the equipment of the production enterprise is old and aging, the production process is not qualified, and the thickness of the paper is uneven; Third, the cord fabric of the paper production machine is not clean and has impurities, which is also an important reason for the unqualified products

a total of 60 batches of film and bag products for food packaging produced by 36 enterprises in the jurisdiction of Harbin were randomly selected by the material testing machine for impact test this time, and 59 batches were qualified after inspection, with a batch qualification rate of 98%. From the spot check, the unqualified products and unqualified items are mainly the thickness that does not meet the standard requirements. National designers must understand that the minimum thickness specified in the "plastic limit order" and relevant standards should be ≥ 0.025 mm. The measured value is only 0.02 global recycled plastic information: now many new material construction products need to be improved and upgraded, and the old ones need to be introduced. The main reason for the unqualified products is that the enterprise sells in units during the sales process. During the production process, the raw materials are increased by the number of bags, deliberately thinning the thickness of the bags

a total of 70 batches of benzene board (including extruded board) and color steel plate products produced by 31 Enterprises in Harbin urban area were spot checked, of which 17 were 30 batches of benzene board, 30 batches were qualified, and the batch qualification rate was 100%; There are 14 color steel plates with 40 batches, 39 of which are qualified, and the batch qualification rate is 97.5%. The unqualified items of unqualified products are mainly that the thickness of color steel plate fails to meet the standard requirements. Compared with traditional materials, the national standard gb/stipulates that the thickness of steel plate should be ≥ 0.5 mm, while the measured value is 0.4 mm. The main reason for unqualified products is that individual enterprises unilaterally pursue profits and purchase raw materials with poor quality for processing and production

a total of 10 batches of tableware detergent products produced by 6 enterprises in the jurisdiction of Harbin were sampled, and 10 batches passed the inspection, with a batch pass rate of 100%. From the perspective of supervision and random inspection, although the qualified rate of this random inspection is 100%, experts remind that there are still certain hidden risks. Unqualified tableware detergent mainly has the problems of unqualified indicators such as total active substances, formaldehyde, total bacterial count, etc., among which total active substances are important indicators to determine the decontamination effect of tableware detergent when washing tableware. Some manufacturers reduced the content of surfactant in order to reduce production costs, resulting in the unqualified index

the Bureau will deal with the production enterprises of unqualified products in this supervision and random inspection according to the relevant laws and regulations
