2020年2月20日，响应国家号召，允迪特立生产线制作医用防护服材料。鑫思创积极支持，并遣技术人员赴厂调试失重计量秤，确保生产顺利。允迪薄膜是国内规模最大的多色印刷定位切透气底膜供应商。 2020.02.20,In response to the national call, Yundi began to produce medical protective clothing materials. Thinkstron actively supports and dispatched engineers to the factory to debug the feeders to ensure the smooth production.Yundi is the largest breathable film supplier in China. 鑫思创HIM应用 PE透气料PE breathable film 医用防护服的要求是“三拒一抗”（即拒水、拒血液、拒酒精以及抗静电）的微纳米级别材料。这种复合材料中，透气薄膜尤为重要，通常以PE为载体制成，具备隔水、透气、导湿功能。 The requirements of medical protective clothing are micro nano materials with "three repellents and one anti-static" (water repellent, blood repellent, alcohol repellent and anti-static). In this kind of compound material, the breathable film is mportant, which is usually made of PE, and has the functions of water separation, air permeability and moisture conduction. 成膜原理Principle PE+CaCO3（母粒） --- 成膜Film forming--- 拉伸Stretch--- 透气膜Breathable film 粒料
PE透气膜是在LDPE/LLDPE聚乙烯树脂载体中，添加50%左右的特种碳酸钙进行共混，经挤出成膜后定向拉伸一定倍率而成。由于聚乙烯树脂为热塑性塑性材料，可在一定条件下进行拉伸和结晶，拉伸时聚合物与碳酸钙颗粒之间发生界面剥离，碳酸钙颗粒周围就形成了相互连通的蜿蜒曲折的孔隙或通道，正是这些孔隙和通道赋予了薄膜的透气（湿）功能，从而沟通了薄膜两面的环境。 PE breathable film is made by blending LDPE/LLDPE polyethylene resin with about 50% special calcium carbonate, extruding and forming the membrane, and then stretching at a certain rate. As polyethylene resin is a thermoplastic material, it can be stretched and crystallized under certain conditions. During stretching, polymer and calcium carbonate particles peels off, and there are connected zigzag pores around the calcium carbonate. These pores that endow the film with permeability (humidity) function. 透气原理breathable Principle 当薄膜一侧的水蒸气浓度在大于薄膜另一侧的环境时，形成了一种湿度梯度压力差，形成气体对流，这就是透气膜的基本原理。意味着PE透气膜的气孔类似一种单向阀，具备一定的阻拦功能。 When the concentration of water vapor on one side of the film is greater than the other side, a kind of pressure is formed, which forms gas convection. It means that the air hole of PE breathable film is similar to a one-way valve. 透气薄膜的孔径 允迪薄膜本身拥有数十条先进的透气膜生产线，对生产的每个环节都讲究精益求精。喂料环节中，因为对鑫思创的信任和认可，3条需要喂料的生产线均选择了鑫思创的计量秤，共12台，原料产能可达到1200kg/h。 Yundi film has dozens of advanced production lines, which with strict requirements. In the feeding process, because of the trust and recognition of Thinkstron, the three production lines that need feeders all choose Thinkstron,12 sets altogether, capacity 1200kg / h. 允迪生产线上的鑫思创计量秤 原料成品 鑫思创十分感谢客户的信赖，团队会继续深耕，打造更加精准、稳定、智能的计量秤。 Thinkstron is very grateful for the trust of customers, the team will continue to work hard to produce more accurate, stable and intelligent feeders.
