一次性玉米淀粉餐具的降解共聚物,在任一细微局部里,其空间较佳结构如下:当降解物质被降解之后,整体物质就被分割成一个个单独碎末几何体,而这些几何体分子量大幅度减低,很容易被自然界所消纳。在实际运作过程中重要解决:

In any tiny part of the degradable copolymer of disposable corn starch tableware, its better spatial structure is as follows: after the degradation material is degraded, the whole material is divided into separate pieces of geometry, and the molecular weight of these geometry is greatly reduced, which is easy to be absorbed by nature. In the actual operation process, it is important to solve the following problems:
其一,降解物质和整体物质之间的作用力。
One is the interaction between the degradation material and the whole material.
既然不是化学变化中的共价键力或离子键力,而牛顿万有引力又远远达不到产品强度的要求。因此,解决使其尽可能具有微观空间下的分子间作用力的问题。这是能降解共聚物生成难度的初个症结。
Since it is not covalent bond force or ionic bond force in chemical change, Newton's gravitation is far from meeting the requirements of product strength. Therefore, it is necessary to solve the problem of intermolecular force in micro space. This is the initial crux of the difficulty in the formation of degradable copolymers.
其二,解决降解物质和整体物质之间的不融合性。
Second, to solve the problem of non fusion between the degradation material and the whole material.
以淀粉和PE为例,前者为强极性分子,后者为非极性分子,两者不是相融、兼容,而是相憎相离,分子间作用力的形式单一,作用力较小。解决的办法,是在两者之间加入交联剂、偶联剂、表面活性剂等物质。这是能降解共聚物生成难度的第2个症结。

Taking starch and PE as an example, the former is a strong polar molecule, the latter is a non-polar molecule, the two are not compatible, but hate each other, the form of intermolecular force is single, the force is small. The solution is to add crosslinking agent, coupling agent, surfactant and other substances between them. This is the second difficulty in the formation of degradable copolymers.
当然,在进入到一次性玉米淀粉餐具实际批量生产时,还要辅之以特定的引发剂、自氧化剂等等,使合成树脂体系结构在光、热、氧以及微生物的化学作用下,发生自主基的连锁反应而使其分子量大幅度减低从而达到深部降解。
Of course, in the actual mass production of disposable corn starch tableware, special initiators, self oxidants and so on should be supplemented to make the structure of synthetic resin undergo chain reaction of self radical under the chemical action of light, heat, oxygen and microorganism, so as to greatly reduce its molecular weight and achieve deep degradation.
勿容置疑,在新的降解树脂共混合体中,塑料等传统树脂不是单独连续的结构。新式共混整体应该是处处近似均匀,处处近似连续的相异多粒子体。另外,为了接近优良空间,每种组份的颗粒还应该周全地小。
There is no doubt that traditional resins such as plastics are not isolated and continuous structures in the new degradable resin blends. The new blends should be homogeneous and continuous. In addition, in order to get close to the excellent space, the particles of each component should be small.
一次性玉米淀粉餐具有节约木材、保护森林资源、保护自然环境的重要意义,又能引导原塑料制品行业在其坚实的生产基础上转产新的产品。。
One time corn starch meal is of great significance in saving wood, protecting forest resources and protecting the natural environment. It can also guide the original plastic products industry to transfer to new products on the basis of its solid production..
