一次性玉米澱粉餐具降（jiàng）解共聚物的分析

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（zuò）用力。

One is the interaction between the degradation material and the whole material.

既然不是化學（xué）變化中的共價鍵力或（huò）離子鍵力，而牛頓萬有引力又（yòu）遠遠達不到產品強度（dù）的要求。因此，解決使（shǐ）其盡可能（néng）具有微觀空間下的分（fèn）子間作用力的問題。這是能降解共聚物生成難度的初個症結。

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（wù）質和整體物質（zhì）之間的不融合性。

Second, to solve the problem of non fusion between the degradation material and the whole material.

以澱粉和PE為例，前者（zhě）為強極性分子（zǐ），後（hòu）者為非（fēi）極性分子，兩者不是相融、兼容，而是（shì）相憎相離，分子間作用力的形式單一，作用力較小。解（jiě）決的（de）辦法，是在兩者（zhě）之間加入交聯劑（jì）、偶聯劑、表麵活性劑（jì）等物質。這是（shì）能降解共聚物生成難度的第2個症結。

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（xìng）玉米澱粉餐（cān）具實際批量生產時（shí），還要輔之以特定的引發劑、自氧化劑（jì）等等，使合成樹脂體係結構在光、熱、氧以及微生物的化學作用下，發生自主基的連（lián）鎖反應而使其分子量大（dà）幅（fú）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（róng）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（xù）的相異多粒子體。另外，為（wéi）了接（jiē）近優良（liáng）空間，每種組份的顆粒還應該（gāi）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.

一次性玉米澱粉餐具有節約木材、保（bǎo）護森林資源、保護自然環境的重要意義，又能引導原（yuán）塑（sù）料製品行業在其堅實的生產（chǎn）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..
