The analysis of thermal properties according to TGA/DTA data as well as the results of studying the composition of volatile products, and the molecular weight characteristics of individual components and blends are presented. The conducted studies have shown that the introduction of high-viscosity unimodal HDPE into bimodal PE100 makes it possible to control the rheological characteristics of the material, shifting the “melt breakdown” to the area of high shear rates, i.e. to increase the processability of the original PE 100, and expand the processing range, which may be useful in the production of extruded sheets and profile products. At the same time, the strength characteristics of the finished product will remain at the level of PE100.","PeriodicalId":20254,"journal":{"name":"Plasticheskie massy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90557384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been established that during the processing of DFPCM with the DS, LFS, and MFS-1 structure types by traditional methods (extrusion, injection molding, etc.), there are practically no technological difficulties. Systems with the type of structure MFS-2 and HFS have an increased viscosity (~7–15 times) in comparison with unfilled EVA; therefore, they cannot be processed.The results of the experiments and the approach developed in this work makes it possible to design DFPCM compositions with adjustable structural parameters and a set of properties, as well as to choose methods and technological parameters for processing them into products with a given shape, configuration, and dimensions.","PeriodicalId":20254,"journal":{"name":"Plasticheskie massy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76591043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Motor oil, vacuum oil, household lubricating oil and polymethyl-siloxane fluid were used as antifriction additives.

The influence of oils on the complex of physico-mechanical, thermal and operational properties has also been studied. It was found that the use of oils at the synthesis stage helps to reduce the coefficient of friction of the samples compared with the control sample. The best effect is observed when using 5 7 wt.% of petroleum oils (a decrease of 50 66% compared to the control sample). The water absorption of oil-filled polycaproamide samples containing petroleum oils is also reduced (by 37% compared to the control sample).

The main assumptions in the task definition were made on the basis of the high viscosity of the liquid and its low thermal diffusivity. The Brinkman equation is used as a motion equation. The flow is accompanied by a chemical reaction, resulting in a sharp increase in viscosity. The viscosity is considered to depend on the temperature and the degree of conversion. This, in turn, led to the inclusion of the kinetic equation of a chemical reaction in the mathematical model. The energy equation is denoted using a single-temperature model and includes dissipative heat emissions. The problem is solved for temperature first-order boundary conditions. The calculations are given for the Nusselt number distribution and the velocity profile transformation. The task was solved numerically by the finite difference method using iterations.","PeriodicalId":20254,"journal":{"name":"Plasticheskie massy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90955575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
