Tianjin announced the sampling results of 49 products: the pass rate is 97.77%

January 2015 and a large plastic deformation occurred at the thinnest place. On January 14,

[China paint information] the official of Tianjin market and quality supervision and Administration Commission informed Tianjin on the 12th of the third batch of product quality supervision and random inspection in 2014, and a total of 627 batches of products produced by 601 production enterprises were selected, 613 batches are qualified, and the qualified rate is 97.77%

according to the report, 49 products were supervised and spot checked in 2014. Among them, the qualified rate of 41 products such as LED light sources, lamps and electric water heaters is 100%. In addition, the qualified rate of customized glasses is 98.28%, the qualified rate of wires and cables is 96%, the qualified rate of interior wall coating is 94.74%, the qualified rate of diapers is 92.31%, the qualified rate of engine coolant is 87.5%, the qualified rate of lubricating oil is 83.33%, the qualified rate of battery is 83.33%, and the qualified rate of exterior wall coating is 81.48%, which is an expansion from 2017

in this sampling inspection, it was found that five batches of exterior wall coating materials produced by five enterprises, including Tianjin jifuzhi coating Co., Ltd., Tianjin dorite coating Co., Ltd., Tianjin Ninghe fengyongmao coating factory, Tianjin meibaili coating products factory, Tianjin Yueyue Shuangyan coating manufacturing Co., Ltd., and one batch of interior wall coating produced by Tianjin Jiayi Coating Factory (general partnership), were detected with unqualified contrast rate items

the contrast rate item is a test item for white and light colored paint. It refers to the ratio of reflectivity of the same paint film applied to the black and white substrates with specified reflectivity, which can reflect the ability of white and light colored paint to eliminate the color or color difference on the substrate, and can also indirectly reflect the amount of paint used to cover the same area of substrate. If the project is unqualified, the covering effect of emulsion paint will be poor, and the paint will lack due protection and decorative functions. The main reason for the unqualified contrast rate project is that the quality control of raw materials is not strict enough. Unqualified raw materials may lead to the unqualified contrast rate of laminated materials, fiber-reinforced thermosetting and thermoplastic composites. At the same time, if the product formula is unreasonable and the raw material ratio is improper, the project will also be unqualified

two batches of lubricating oil products are unqualified. A batch of Zhongfu Samsung lubricating oil from Tianjin Zhongfu Petrochemical Products Co., Ltd. was found to be unqualified in the low-temperature dynamic viscosity (-25 ℃); A batch of Shengdi lubricating oil from Tianjin Shengdi Petroleum Products Co., Ltd. was found to be unqualified in terms of kinematic viscosity (100 ℃). Low temperature dynamic viscosity is a measure of the internal friction force of lubricating oil measured at low temperature and high shear rate, and can be used as a viscosity index to judge whether the engine can start smoothly at low temperature. The kinematic viscosity (100 ℃) is the indication of the operation of lubricating oil under the condition of 100 ℃. Too viscous or too thin will directly affect the service performance of lubricating oil. The kinematic viscosity should be within the range of standard requirements to ensure the normal use of lubricating oil

two batches of customized glasses products are unqualified. Tianjin Ninghe Hongxuan glasses store detected that a batch of customized glasses were unqualified in terms of lens transmittance performance; Tianjin Binjiang Commercial Building Co., Ltd. detected that a batch of fixed glasses were unqualified in the vertex power deviation project

in addition, one batch of products of wire and cable, diapers, engine coolant and battery are unqualified. A batch of houshengtang baby care urine pads from Tianjin Yinghua maternal and child products Co., Ltd. were found to be unqualified in terms of permeability. The pH value and glassware corrosion of a batch of laotefoss engine coolant of Tianjin Zhongde laotefoss Petroleum Products Co., Ltd. were detected to be unqualified; A batch of Jiangbei wires and cables of Tianjin Jiangbei wire and cable Co., Ltd. were found to be unqualified in terms of conductor resistance, tensile strength before insulation aging, tensile strength after insulation aging, change rate of tensile strength before and after insulation air bomb aging, change rate of elongation at break before and after insulation air bomb aging, ozone resistance test of insulation, and tensile strength before sheath aging; A batch of batteries of BIC International (Tianjin) Co., Ltd. were detected to be unqualified in the -20 ℃ discharge capacity project

Tianjin municipal market and quality supervision and Administration Commission said that it would carry out post-treatment work for unqualified product manufacturers, issue a rectification notice to unqualified product manufacturers, and require enterprises to rectify within a time limit. Urge the enterprise to rectify and recheck, and do not continue to produce and sell products of the same specification and model until they are qualified
