? PLA降解片材/卷材擠出生產(chǎn)線設(shè)備 
       ?PLA Degradable Sheet/Rolls Sheet Extrusion Production Line Equipment
       PLA主要成分乳酸大多通過淀粉等發(fā)酵制備得到，工藝和技術(shù)已經(jīng)成熟。是無色、光滑的硬塑料，高強(qiáng)度、高模量，其力學(xué)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 Degradable Sheet/Rolls Sheet Extrusion Production Line Equipment 
      PBAT是脂肪族-芳香族共聚酯，結(jié)晶率低，分子鏈有柔性的脂肪鏈和剛性的芳環(huán)，具有優(yōu)良的力學(xué)性能，可自然降解。廣泛用于地膜、膜袋包裝等領(lǐng)域，是目前發(fā)展最快、應(yīng)用最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 Degradable Sheet/Rolls Sheet Extrusion Production Line Equipment
      PBS（直接酯化法）,具有較高的熔點(diǎn)，略作改性就能夠承受100℃的高溫，降解性能優(yōu)異，可在自然條件下進(jìn)行生物降解。且加工方便、耐熱性好、綜合力學(xué)性能優(yōu)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(nóng)業(yè)領(lǐng)域（農(nóng)用薄膜、化肥緩釋材料），還可以用于醫(yī)用領(lǐng)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.
