一次性玉米淀粉餐具的降解共聚物，在任一細(xì)微局部里，其空間較佳結(jié)構(gòu)如下:當(dāng)降解物質(zhì)被降解之后，整體物質(zhì)就被分割成一個(gè)個(gè)單獨(dú)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(shí)際運(yùn)作過程中重要解決：

The degradable copolymer of disposable corn starch tableware, in any small part, has a better spatial structure as follows: when the degradable material is degraded, the whole material is divided into separate fragments of geometry, and the molecular weight of these geometries is greatly reduced, which is easily absorbed by nature. Important solutions in the actual operation process:

其一，降解物質(zhì)和整體物質(zhì)之間的作用力。

First, the force between the degradable substance and the whole substance.

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(gè)癥結(jié)。

Since it is not the covalent bond force or ionic bond force in chemical changes, Newton's gravity is far from meeting the requirements of product strength. Therefore, the problem of making it have intermolecular force in microcosmic space as much as possible is solved. This is the first crux of the difficulty in the formation of biodegradable copolymers.

其二，解決降解物質(zhì)和整體物質(zhì)之間的不融合性。

The second is to solve the incompatibility between degradable substances and the whole substance.

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)。

Take starch and PE for example. The former is a strong polar molecule, and the latter is a non-polar molecule. The two are not compatible and compatible, but are mutually exclusive. The form of intermolecular force is single, and the force is small. The solution is to add crosslinking agent, coupling agent, surfactant and other substances between the two. This is the second crux of the difficulty in the formation of biodegradable 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, when it comes to the actual batch production of disposable corn starch tableware, it should be supplemented with specific initiators, autoxidants, etc., so that the synthetic resin system structure will undergo the chain reaction of autogenous radicals under the chemical action of light, heat, oxygen and microorganisms, which will 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(tǒng)樹脂不是單獨(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 in the new degradable resin blend, traditional resins such as plastics are not separate and continuous structures. The whole of the new blend should be a heterogeneous multi-particle body which is nearly uniform and continuous everywhere. In addition, in order to approach the excellent space, the particles of each component should also be small.
