    ?PLA Degradable Sheet/Rolls Sheet Extrusion Production  Line Equipment

       PLA主要成分乳酸大多通过淀粉等发酵制备得到,工艺和技术已经成熟。是无色、光滑的硬塑料,高强度、高模量,其力学性能与PS相似,拉伸以及弯曲模量高于HDPE,但是本身韧性较差。适宜注塑、吹塑、热成型、挤出、流延、熔融纺丝和静电纺丝等多种加工工艺。主要用于包装和纤维。

        Lactic acid, the main component of PLA, is mostly prepared by fermentation of starch, and the process and technology are mature. It is a colorless, smooth hard plastic with high strength and high modulus. Its mechanical properties are similar to PS, and its tensile and flexural modulus are higher than HDPE, but its toughness is poor. It is suitable for various processing processes such as injection molding, blow molding, thermoforming, extrusion, casting, melt spinning and electrospinning. Mainly used for packaging and fibers. also be used as engineering plastics in machinery, chemical and other equipment, and is widely used in drainage boards.

        PBAT是脂肪族-芳香族共聚酯,结晶率低,分子链有柔性的脂肪链和刚性的芳环,具有优良的力学性能,可自然降解。广泛用于地膜、膜袋包装等领域,是目前发展快、应用广泛的降解塑料品种之一。

       PBAT is an aliphatic-aromatic copolyester with low crystallization rate, flexible aliphatic chain and rigid aromatic ring in the molecular chain, excellent mechanical properties and can be naturally degraded. Widely used in plastic film, film bag packaging and other fields, it is one of the fastest growing and most widely used degradable plastic varieties.

         PBS(直接酯化法),具有较高的熔点,略作改性就能够承受100℃的高温,降解性能优异,可在自然条件下进行生物降解。且加工方便、耐热性好、综合力学性能优异、用途广泛,既可以用于可降解包装(食品袋、瓶子、餐盒餐具)、农业领域(农用薄膜、化肥缓释材料),还可以用于医用领域(如人造软骨、缝合线、支架)等。

         PBS (direct esterification method) has a high melting point, can withstand a high temperature of 100 ° C with a little modification, has excellent degradation performance, and can be biodegraded under natural conditions. Moreover, it is easy to process, has good heat resistance, excellent comprehensive mechanical properties, and has a wide range of uses. In the medical field (such as artificial cartilage, sutures, stents), etc.
