         day front, new 疆维吾尔自治区 market tube/pipe 理局网站公布2019 year 自治区 polyethylene (PE) blow molding use cover/cap film product quality 监督抽查结果, polyethylene (PE) blow molding use cover/cap film product combined 格检出 rate is 27.78%.

        本次抽查12 州市54家 enterprise production 54 batch product, 检出15 batch combined product. combined project main/primary is: thick degree, toward tensile negative 荷(人工 gas aging front), toward 直角撕裂 negative 荷, toward tensile negative 荷(人工 gas aging rear), toward fracture 标称应变(人工 gas aging rear), ash content.

        不 combined project for product effect/influence: 1.纵 toward 直角撕裂 negative 荷达不 to standards requirements, make use film accelerated expand large or 延伸, 导致农 use film easy loss, to temperature, wet function. 2.人工 gas aging rear tensile negative 荷达不 to standards requirements, 会导致农 use film front aging, cracking, shrink short its use lifespan.

        不 combined causes analysis: is equipment 陈旧. due to separation film enterprise production 规模不 large, large separation processing equipment 陈旧落 rear, processing degree decline, processing process unstable. is Raw Materials quality can has control. is reduce cost, a large amount of add recycled material, anti-aging and other property can combined 格. is for raw materials ratio control to 位. Raw Materials according to experience ratio, product quality unstable.
