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 degradation copolymer of disposable corn starch tableware has the optimal spatial structure in any small area as follows: when the degradation material is degraded, the overall material is divided into individual fragmented geometric bodies, and the molecular weight of these geometric bodies is greatly reduced, making them easily absorbed by nature. In the actual operation process, it is important to address:

其一,降解物質(zhì)和整體物質(zhì)之間的作用力。

One is the interaction force between the degrading substance and the overall 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 covalent bonding force or ionic bonding force in chemical changes, and Newton's universal gravitation is far from meeting the requirements of product strength. Therefore, it is necessary to address the issue of maximizing the intermolecular forces in the microscopic space. This is the first crux of the difficulty in generating biodegradable copolymers.

其二,解決降解物質(zhì)和整體物質(zhì)之間的不融合性。

Secondly, address the non fusion between degradable substances and overall substances.

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 examples, the former is a strongly polar molecule, while the latter is a non-polar molecule. The two are not compatible or compatible, but rather mutually exclusive. The form of intermolecular forces is single, and the forces are relatively small. The solution is to add crosslinking agents, coupling agents, surfactants, and other substances between the two. This is the second crux of the difficulty in generating 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 entering the actual mass production of disposable corn starch tableware, specific initiators, self oxidizers, etc. need to be supplemented to make the synthetic resin system structure undergo a chain reaction of self radicals under the chemical action of light, heat, oxygen, and microorganisms, resulting in a significant reduction in its molecular weight and 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。

Undoubtedly, in the new degradation resin blend, traditional resins such as plastic are not individually continuous structures. The new type of blending should be a heterogeneous multi particle body that is approximately uniform and continuous everywhere. In addition, in order to approach the optimal space, the particles of each component should also be carefully small.
