The Effect of a Zinc-Containing Additive on the Properties of PVC Compounds

Abstract

Polymeric materials that undergo degradation under the influence of biological media have attracted widespread attention in recent decades. This is due to the ability to eliminate the negative impact on the environment, gradually reducing the scale of plastic waste pollution. At the same time, it remains relevant to ensure the necessary performance characteristics of products for a certain period of use. An important direction in the field of biodegradable composite compositions is the development of nontoxic additives in order to ensure their safe interaction with biological media. In this regard, a method has been developed for the joint production of a new nontoxic plasticizer decyl phenoxyethyl adipate and a biocidal additive of zinc decyl adipate. The effect of the obtained additives on the biodegradation of PVC film samples under natural conditions was studied. The period of biocidal action of zinc compound formed in situ in an amount of 0.3% in the composition of PVC films using the developed plasticizer was determined.

Application of Rhino Modeling Software in Product Fading Surface Modeling Design from the Perspective of Computer

“…It mainly studies the representation, design, analysis, and speci cation processing of curves and surfaces. With the development of computer graphics, a new technology focuses more on curve and surface design, splicing, modeling, display, and morphological analysis [1]. As people have higher and higher requirements for product shape, product modeling has become more complex, and practical problems such as product design and manufacturing have a deeper connection with curve and surface modeling optimization.…”
