  可降解的一次性玉米淀粉餐具類共聚物,在任何一小部分,有更好的空間結(jié)構(gòu)如下:可降解物質(zhì)退化時(shí),整個(gè)物質(zhì)分為單一幾何的碎片,和分子量的幾何是大大減少,這是容易吸收的性質(zhì)。實(shí)際操作過程中的重要解決方案:

  The degradable disposable corn starch tableware copolymers, in any small part, have better spatial structure as follows: when the degradable material degenerates, the whole material is divided into single geometric fragments, and the molecular weight geometry is greatly reduced, which is easy to absorb. Important solutions in practical operation:
  ,降解材料和整個(gè)材料之間的力。
  First, the forces between the degradation material and the whole material.
  由于化學(xué)變化不是共價(jià)鍵合力或離子鍵合力,牛頓引力遠(yuǎn)遠(yuǎn)不能滿足產(chǎn)品強(qiáng)度的要求。因此,使其在微觀空間下具有盡可能多的分子間作用力的問題得到了解決。這是形成可降解共聚物的更初難點(diǎn)所在。
一次性玉米淀粉餐具
  Because chemical changes are not covalent or ionic bond forces, Newtonian gravity is far from meeting the requirements of product strength. Therefore, the problem of having as many intermolecular forces as possible in micro space has been solved. This is the initial difficulty in the formation of degradable copolymers.
  二是解決降解物質(zhì)與整體物質(zhì)的不整合問題。
  The second is to solve the problem of the unconformity between the degradation substance and the whole substance.
  以淀粉和PE為例,前者是強(qiáng)極性分子,后者是非極性分子,兩者并不協(xié)調(diào)、相容,而是相互仇恨,分子間力的形式單一,力小。解決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)。這是形成可降解共聚物的第二個(gè)難點(diǎn)。
  Take starch and PE for example. The former is a strong polar molecule, while the latter is a nonpolar molecule. They are not compatible and harmonious, but hate each other. The form of intermolecular force is single and the force is small. The solution is to add cross-linking agent, coupling agent, surfactant and other substances between the two. This is the second difficulty in the formation of degradable copolymers.
  當(dāng)然,在可支配的實(shí)際批量生產(chǎn)玉米淀粉餐具,還輔以具體的發(fā)起者,self-oxidant等等,合成樹脂系統(tǒng)結(jié)構(gòu)的光,熱,氧和微生物化學(xué)作用,獨(dú)立基礎(chǔ)的連鎖反應(yīng),因此其分子量是大大減少實(shí)現(xiàn)深度降解。
  Of course, in the actual batch production of corn starch tableware, supplemented by the specific initiator, self oxident, etc., the light, heat, oxygen and Microbial Chemistry of the synthetic resin system structure, independent and basic chain reaction, so its molecular weight is greatly reduced to achieve deep degradation.
  毫無疑問,傳統(tǒng)的樹脂,如塑料,在新的組合中不是單一的連續(xù)結(jié)構(gòu)。整個(gè)新的共混物應(yīng)該是一個(gè)幾乎處處均勻、處處幾乎連續(xù)的多相粒子體。此外,每個(gè)組成部分的粒子都應(yīng)該是小的,以便接近一個(gè)良好的空間。
  There is no doubt that traditional resins, such as plastics, are not a single continuous structure in the new combination. The whole new blend should be a homogeneous and continuous multiphase particle. In addition, the particles of each component should be small so as to approach a good space.
  一次性玉米淀粉餐具具有節(jié)約木材、保護(hù)森林資源和保護(hù)自然環(huán)境的重要意義,可以指導(dǎo)原塑料制品行業(yè)在其堅(jiān)實(shí)的生產(chǎn)基礎(chǔ)上生產(chǎn)新產(chǎn)品。
  Disposable corn starch tableware is of great significance in saving wood, protecting forest resources and protecting natural environment. It can guide the original plastic products industry to produce new products on its solid production basis.
