The degradable copolymer of disposable cornstarch tableware, in any small part, the better spatial structure is as follows: When the degraded material is degraded, the whole material is divided into individual broken geometric bodies, and the molecular weight of these geometric bodies is greatly reduced , It is easily absorbed by nature. It is important to solve in the actual operation process:
One is the force between the degradable substance and the overall substance.
Since it is not the covalent bond force or ionic bond force in chemical changes, Newton's universal gravitation is far from reaching the requirements of product strength. Therefore, the problem of making it possible to have intermolecular forces in the microscopic space is solved. This is the first crux of the difficulty of degradable copolymer formation.
The second is to solve the disintegration between degradable substances and overall substances.
Take starch and PE as examples. The former is a strong polar molecule, and the latter is a non-polar molecule. The two are not fused and compatible, but dissociated from each other. The force between the molecules is in a single form 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 crux of the difficulty of degradable copolymer formation.
Of course, when entering the actual mass production of disposable corn starch tableware, it must be supplemented with specific initiators, self-oxidizing agents, etc., so that the synthetic resin system structure will be autonomous under the chemical action of light, heat, oxygen and microorganisms. The chain reaction of the radicals greatly reduces its molecular weight to achieve deep degradation.
Undoubtedly, in the new degradable resin blend, traditional resins such as plastics are not a single continuous structure. The new blend should be a dissimilar multi-particle body that is approximately uniform everywhere and continuous everywhere. In addition, in order to be close to a good space, the particles of each component should also be sufficiently small.
The one-time corn starch meal is of great significance to save wood, protect forest resources, and protect the natural environment. It can also guide the original plastic products industry to switch to new products on its solid production basis.
