| 多层复合技术利用具有中高阻隔性能的材料与其他包装材料复合，综合阻隔材料的高阻隔性与其他材料的廉价或特殊的力学、热学等其他性能，实现特定的功能需要。共挤出复合薄膜的结构设计逐步要求能系统地达到集功能、技术、成本、环保、安全、二次加工于一体的理想境界，从而实现复合层数最大化的可能性成为供应商追求的技术之一。 Multilayer composite technology utilizes materials with medium and high barrier properties to compound with other packaging materials. It integrates the high barrier properties of barrier materials with other guangdaon.37ix.com.cnchoushag.37ix.com.cntuoliutayq.37ix.com.cn zujuji.37ix.com.cnmaterials'cheap jiaoni.07858.netbuxiugang.37ix.com.cnor special mechanical and thermal properties to achieve specific functional needs. The structural design of co-extrusion composite film gradually requires that the ideal state of function, technology, cost, environmental protection, safety and secondary processing be systematically achieved, so that the possibility of maximizing the number of composite layers becomes one of the technologies pursued by suppliers. 该七层复合薄膜共挤吹塑机组采用的关键技术包括：两短一长及螺距变化的螺杆塑化挤出系统，工程分析软件对振动诱导塑化装置的优化设计，平面阀加成型模头和斜式阀加成型模头，内冷技术及双风口负压冷却技术，多组分失重式计量喂料，在线薄膜厚度精确控制系统，计算机集中自动控制系统和总线控制（CANOPEN）技术等。 The key technologies adopted by the seven-layer composite film co-extrusion blow-moulding unit include: screw plasticizing extrusion system with two short and one long and variable pitch, optimization design of vibration-induced plasticizing device by engineering analysis software, plain valve moulding die and inclined valve moulding die, internal cooling technology and double-tuyere negative pressure cooling technology, multi-component weightlessness metering feeding, on-line film thickness precise control. System, computer centralized automatic control system and bus control (CANOPEN) technology. |
