可降解颗粒是使用植物(如玉米 木薯等)作为原料合成的全降解材料。具有良好的生物相容性,很容易被降解。也是目前应用范围比较广的热氧可降解塑料颗粒。可用于吹膜,挤出,注塑,纺丝等。可以用来制作包装膜,塑料袋,农膜,一次性餐具,口罩无纺布等等。PLA具有的高光泽度合透明度,可以在一些领域替代PET和PC制作的水杯,食品包装盒

Thermooxidative degradable plastic particles are fully degradable materials synthesized from plants (such as corn, cassava, etc.). It has good biocompatibility and is easy to be degraded. It is also a thermal oxygen degradable plastic particle with a wide range of applications. It can be used for film blowing, extrusion, injection molding, spinning, etc. Can be used to make packaging film, plastic bags, agricultural film, disposable tableware, masks, non-woven fabrics and so on. PLA has high gloss and transparency, which can replace pet and PC water cup and food packaging box in some fields
Degradable particles
热氧可降解塑料颗粒是由含糖、淀粉、纤维素等生物质材料为原料,经发酵制成乳酸,再由乳酸聚合制成聚乳酸高分子材料而成。因为热氧可降解塑料颗粒具有良好的生物相容性、可降解性和来源于生物原材料等特点,研究者认为 热氧可降解塑料颗粒是应用前景比较好的一种热氧可降解塑料颗粒。
Thermooxidative degradable plastic particles are made of sugar, starch, cellulose and other biomass materials as raw materials, fermented into lactic acid, and then polymerized by lactic acid to produce polylactic acid polymer materials. Due to the good biocompatibility, biodegradability and the characteristics of raw materials derived from biological materials, the thermal oxygen degradable plastic particles are considered to be a kind of thermal oxygen degradable plastic particles with good application prospects.
可降解颗粒
虽然热氧可降解塑料颗粒有很多优点,但是在现实应用中也存在很多不足: 如 热氧可降解塑料颗粒 的韧性比较差,缺少弹性以及柔性,质地硬而且脆性大,溶体强度相对较低,结晶速率过慢等,上述缺陷限制了其在很多方面的应用。热氧可降解塑料颗粒的化学结构中含有大量的酯键,导致其亲水性差,降解速率需要控制等。而且 热氧可降解塑料颗粒 价格较高,增加了原料成本,也限制了其在商业上的推广。因此,针对以上诸多缺点,对 热氧可降解塑料颗粒 进行改性成为近些年国内外相关科研人员主要研究的方向。以期改善材料性能和降解产品成本。
Although thermal oxygen degradable plastic particles have many advantages, they also have many disadvantages in practical application, such as poor toughness, lack of elasticity and flexibility, hard and brittle texture, relatively low strength of solution, slow crystallization rate, etc. these defects limit its application in many aspects. There are a lot of ester bonds in the chemical structure of thermo oxidative degradable plastic particles, which leads to poor hydrophilicity and the degradation rate needs to be controlled. Moreover, the high price of thermal oxygen degradable plastic particles increases the cost of raw materials and limits its commercial application. Therefore, in view of the above shortcomings, modification of thermal oxygen degradable plastic particles has become the main research direction of domestic and foreign researchers in recent years. In order to improve the material properties and degradation product cost.
热氧可降解塑料颗粒是基于材料共混改性完成的。共混改性是在保持聚合物原有的优良性能的前提下,有针对性地对其某些有缺陷的物理机械性能进行改进,同时使生产成本降低。因此是目前应用广泛的改性聚合物的方法。目前,根据共混组分的类型不同,热氧可降解塑料颗粒共混体系可大致分为增塑剂共混、成核剂共混、无机填料共混、天然纤维共混以及其他可降解材料共混等。
Thermooxidative degradable plastic particles are based on the blending modification of materials. Blending modification is to improve some defective physical and mechanical properties of the polymer while maintaining its original excellent properties, and reduce the production cost at the same time. Therefore, it is a widely used method to modify polymer. At present, according to the different types of blending components, the thermal oxygen degradable plastic particle blending system can be roughly divided into plasticizer blending, nucleating agent blending, inorganic filler blending, natural fiber blending and other degradable materials blending.
