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(zhì)和整體物質(zhì)之間的作用力。

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(jià)鍵力或離子鍵力，而牛頓萬(wàn)有引力又遠(yuǎn)遠(yuǎn)達(dá)不到產(chǎn)品強(qiáng)度的要求。因此，解決使其盡可能具有微觀(guān)空間下的分子間作用力的問(wèn)題。這是能降解共聚物生成難度的初個(gè)癥結(jié)。

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(zhì)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.

以淀粉和PE為例，前者為強(qiáng)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(lián)劑、偶聯(lián)劑、表面活性劑等物質(zhì)。這是能降解共聚物生成難度的第2個(gè)癥結(jié)。

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(dāng)然，在進(jìn)入到一次性玉米淀粉餐具實(shí)際批量生產(chǎn)時(shí)，還要輔之以特定的引發(fā)劑、自氧化劑等等，使合成樹(shù)脂體系結(jié)構(gòu)在光、熱、氧以及微生物的化學(xué)作用下，發(fā)生自主基的連鎖反應(yīng)而使其分子量大幅度減低從而達(dá)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(shù)脂共混合體中，塑料等傳統(tǒng)樹(shù)脂不是單獨(dú)連續(xù)的結(jié)構(gòu)。新式共混整體應(yīng)該是處處近似均勻，處處近似連續(xù)的相異多粒子體。另外，為了接近優(yōu)良空間，每種組份的顆粒還應(yīng)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(jié)約木材、保護(hù)森林資源、保護(hù)自然環(huán)境的重要意義，又能引導(dǎo)原塑料制品行業(yè)在其堅(jiān)實(shí)的生產(chǎn)基礎(chǔ)上轉(zhuǎn)產(chǎn)新的產(chǎn)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..
