    ?PLA Degradable Sheet/Rolls Sheet Extrusion Production  Line Equipment

       PLA主要成分乳酸大多通過淀粉等發酵制備得到,工藝和技術已經成熟。是無色、光滑的硬塑料,高強度、高模量,其力學性能與PS相似,拉伸以及彎曲模量高于HDPE,但是本身韌性較差。適宜注塑、吹塑、熱成型、擠出、流延、熔融紡絲和靜電紡絲等多種加工工藝。主要用于包裝和纖維。

        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,結晶率低,分子鏈有柔性的脂肪鏈和剛性的芳環,具有優良的力學性能,可自然降解。廣泛用于地膜、膜袋包裝等領域,是目前發展快、應用廣泛的降解塑料品種之一。

       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),具有較高的熔點,略作改性就能夠承受100℃的高溫,降解性能優異,可在自然條件下進行生物降解。且加工方便、耐熱性好、綜合力學性能優異、用途廣泛,既可以用于可降解包裝(食品袋、瓶子、餐盒餐具)、農業領域(農用薄膜、化肥緩釋材料),還可以用于醫用領域(如人造軟骨、縫合線、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.
