          一次性玉米淀粉餐具的降解共聚物,在任一細微局部里,其空間較佳結構如下:當降解物質被降解之后,整體物質就被分割成一個個單獨碎末幾何體,而這些幾何體分子量大幅度減低,很容易被自然界所消納。在實際運作過程中重要解決:

          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,降解物質和整體物質之間的作用力。
          One is the interaction between the degradation material and the whole material.
          既然不是化學變化中的共價鍵力或離子鍵力,而牛頓萬有引力又遠遠達不到產品強度的要求。因此,解決使其盡可能具有微觀空間下的分子間作用力的問題。這是能降解共聚物生成難度的初個癥結。
          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,解決降解物質和整體物質之間的不融合性。
          Second, to solve the problem of non fusion between the degradation material and the whole material.
          以淀粉和PE為例,前者為強極性分子,后者為非極性分子,兩者不是相融、兼容,而是相憎相離,分子間作用力的形式單一,作用力較小。解決的辦法,是在兩者之間加入交聯劑、偶聯劑、表面活性劑等物質。這是能降解共聚物生成難度的第2個癥結。
          一次性環保餐具
          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.
          當然,在進入到一次性玉米淀粉餐具實際批量生產時,還要輔之以特定的引發劑、自氧化劑等等,使合成樹脂體系結構在光、熱、氧以及微生物的化學作用下,發生自主基的連鎖反應而使其分子量大幅度減低從而達到深部降解。
          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,在新的降解樹脂共混合體中,塑料等傳統樹脂不是單獨連續的結構。新式共混整體應該是處處近似均勻,處處近似連續的相異多粒子體。另外,為了接近優良空間,每種組份的顆粒還應該周全地小。
          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節約木材、保護森林資源、保護自然環境的重要意義,又能引導原塑料制品行業在其堅實的生產基礎上轉產新的產品。。
          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..
