一次性玉米淀粉餐具降解共聚物的结构分析

　　The degradable disposable corn starch tableware copolymers, in any small part, have better spatial structure as follows: when the degradable material degenerates, the whole material is divided into single geometric fragments, and the molecular weight geometry is greatly reduced, which is easy to absorb. Important solutions in practical operation:

　　，降解材料和整个材料之间的力。

　　First, the forces between the degradation material and the whole material.

　　由于化学变化不是共价键合力或离子键合力，牛顿引力远远不能满足产品强度的要求。因此，使其在微观空间下具有尽可能多的分子间作用力的问题得到了解决。这是形成可降解共聚物的更初难点所在。

　　Because chemical changes are not covalent or ionic bond forces, Newtonian gravity is far from meeting the requirements of product strength. Therefore, the problem of having as many intermolecular forces as possible in micro space has been solved. This is the initial difficulty in the formation of degradable copolymers.

　　二是解决降解物质与整体物质的不整合问题。

　　The second is to solve the problem of the unconformity between the degradation substance and the whole substance.

　　以淀粉和PE为例，前者是强极性分子，后者是非极性分子，两者并不协调、相容，而是相互仇恨，分子间力的形式单一，力小。解决办法是在两者之间加入交联剂、偶联剂、表面活性剂等物质。这是形成可降解共聚物的第二个难点。

　　Take starch and PE for example. The former is a strong polar molecule, while the latter is a nonpolar molecule. They are not compatible and harmonious, but hate each other. The form of intermolecular force is single and the force is small. The solution is to add cross-linking agent, coupling agent, surfactant and other substances between the two. This is the second difficulty in the formation of degradable copolymers.

　　当然,在可支配的实际批量生产玉米淀粉餐具,还辅以具体的发起者,self-oxidant等等,合成树脂系统结构的光,热,氧和微生物化学作用,独立基础的连锁反应,因此其分子量是大大减少实现深度降解。

　　Of course, in the actual batch production of corn starch tableware, supplemented by the specific initiator, self oxident, etc., the light, heat, oxygen and Microbial Chemistry of the synthetic resin system structure, independent and basic chain reaction, so its molecular weight is greatly reduced to achieve deep degradation.

　　毫无疑问，传统的树脂，如塑料，在新的组合中不是单一的连续结构。整个新的共混物应该是一个几乎处处均匀、处处几乎连续的多相粒子体。此外，每个组成部分的粒子都应该是小的，以便接近一个良好的空间。

　　There is no doubt that traditional resins, such as plastics, are not a single continuous structure in the new combination. The whole new blend should be a homogeneous and continuous multiphase particle. In addition, the particles of each component should be small so as to approach a good space.

　　一次性玉米淀粉餐具具有节约木材、保护森林资源和保护自然环境的重要意义，可以指导原塑料制品行业在其坚实的生产基础上生产新产品。

　　Disposable corn starch tableware is of great significance in saving wood, protecting forest resources and protecting natural environment. It can guide the original plastic products industry to produce new products on its solid production basis.
