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:
First, the forces between the degradation material and the whole material.
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.
The second is to solve the problem of the unconformity between the degradation substance and the whole substance.
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.
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.
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.
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.
