Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Foreign production is mainly of polyethylene (PE), mainly for the domestic production of polypropylene (PP), is a thermoplastic resin by polymerization of ethylene obtained. In the industry, but also copolymers of ethylene with small amounts of α- olefins. Polyethylene odorless, non-toxic color woven sack, feel like wax, with excellent low temperature performance (the lowest temperature up -70 ~ -100 ℃), good chemical stability, resistance to most acid-base erosion (not acid having an oxidation-resistant properties), at room temperature, insoluble in common solvents, low water absorption, excellent electrical insulation properties; however polyethylene environmental stress (chemical and mechanical action) is very sensitive, heat aging resistance is poor. Polyethylene nature because of different varieties, depending on the molecular structure and density. Using different production methods can be obtained with different densities (0.91 ~ 0.96g / cm3) of the product. Polyethylene generally available thermoplastics molding method (see plastics processing) processing. Uses a wide range of color bags, mainly used to manufacture film, containers, pipes, monofilament, wire and cable, and other daily necessities, and as television, radar and other high-frequency insulation. With the development of petrochemical industry, the rapid development of polyethylene production, production accounts for about 1 / 4.1983 world total production capacity of polyethylene plastic production is 24.65Mt, the construction unit capacity of 3.16Mt. Type test items for the technical requirements of all the items, under normal circumstances be inspected once a year color woven fertilizer bags, when one of the following circumstances, should be type tested: trial stereotypes identified a) new products or old products plant production; b) After the official production, such as structure, materials, technology has drastically changed, when that may affect product performance; c) the product after long-term shutdown, resume production; d) factory inspection results are quite different when the last type inspection; e) National Quality Supervision and institutions ask for inspection requirements. 6.4 Rule 6.4.1 determine the quality of the sample units determines the appearance of bags and deviations by 4.1, 4.2 can be tested, if all projects are qualified inspection, the sample unit is qualified. 6.4.2 Qualified batch quality determination 6.4.2.1 bag look and qualified to determine the deviation in accordance with GB / T2828 provisions, per hundred units represent the number of nonconforming product batch quality, general inspection level I Pingxiang color printing bags, acceptable quality level (AQL) of 6.5, specific provisions in Table 5. 6.4.2.2 If a tensile load test failed projects should be re-doubling in the original batch sampling for the project failed reinspection, Ruofu test results were satisfactory, it is determined that the batch is acceptable.
