However, the applications of this green material are limited due to the poor thermodynamic incompatibility between PPC and PP. In this paper, PP grafted with maleic anhydride (MAH) and styrene (St) (PP-g-(MAH-co-St)), prepared by a mechanochemical method and having a grafting percentage GMAH = 1.40 %, was used as a compatibilizer to prepare a biodegradable PPC/compatibilizer/PP composite-spunbond nonwoven slice by melt-blending. The effects of compatibilizer content on the tensile strength, elongation at break, melt flow rate, thermal properties, and micro-morphology of PPC/PP-g-(MAH-co-St)/PP were systematically studied. Furthermore, the mechanism of compatibilization of PP-g-(MAH-co-St) in the PPC/PP spunbond nonwoven composite slice is discussed. The results indicated that this green PP-g-(MAH-co-St) exhibited a clear reactive compatibilization effect. Therefore, it can be considered as a good compatibilizer for the biodegradable PPC/PP spunbond nonwoven slice.","PeriodicalId":14410,"journal":{"name":"International Polymer Processing","volume":"38 1","pages":"395 - 403"},"PeriodicalIF":1.3,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46292427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In comparison with shear flow field, extensional flow field has been shown to have unique advantages in improving dispersive mixing performance and reducing energy consumption. However, building an extensional flow field in a conventional single-screw extruder remains challenging. In this work, a new mound-shaped extensional mixing element (M-EME) was designed based on the geometric characteristics of a sine curve. To investigate the effect of this M-EME on the mixing properties of a conventional single-screw extruder, a numerical simulation analysis of this M-EME was performed. The results showed that the proportion of the region with a mixing index greater than 0.55 in the M-EME was higher than 43 %, and that the highest mixing index of the M-EME reached around 0.9, confirming the dominance of the extensional flow field in the M-EME. Moreover, it was observed that the changes in amplitude and period of the sine function have no significant effect on the distribution of the mixing index. The findings from this work provide a viable way to generate extensional flow fields in conventional screw extruders.","PeriodicalId":14410,"journal":{"name":"International Polymer Processing","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45519847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The snake grass and sisal fibers were initially treated with 5% sodium hydroxide (NaOH). Hybrid composite samples were fabricated using a compression moulding technique with a total fiber weight ratio of 30% and an epoxy resin weight ratio of 70%. The proportions of snake grass and sisal fibers in the hybrid composites were 70:30, 50:50, and 30:70. The fabricated hybrid composite samples were subjected to flexural, tensile, interlaminar shear strength, Shore D hardness, water absorption, and wear tests as per ASTM international standards, and the outcomes were compared with the results of snake grass and sisal mono fiber composites. The results disclosed that the 30:70 (SG:S) hybrid composite has higher mechanical characteristics than those of other hybrid and mono fiber composites. Also, the 30:70 hybrid sample performed at par with the sisal mono composite in wear and water absorption characteristics. Optical microscopy examination of alkali-treated natural hybrid and mono fiber composites displayed excellent results in terms of interfacial bonding between polymer and fiber.","PeriodicalId":14410,"journal":{"name":"International Polymer Processing","volume":"38 1","pages":"331 - 342"},"PeriodicalIF":1.3,"publicationDate":"2023-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41446587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Process monitoring and optimization systems are mostly based on processing data of injection molding machine control systems. These data consist of scalar data and time series. This paper introduces a novel approach to modelling injection molding processes using only time series data and evaluates the quantitative influences of varying sampling times on calculation of integral values and model quality. On the basis of the first experiment, it is shown that the sampling rates of these time series have a large influence on information which can be derived from this data (e.g. injection work). These findings provide an assessment of whether the effort is justified for the respective requirements on the accuracy of the injection work and other parameters derived from the time series. In the second experiment, a model is presented which uses only the injection flow and injection pressure profile as input and achieves high coefficients of determination for the prediction of the part weight, despite the absence of mold sensor data and scalar data. It is shown that higher sampling rates of time series results in higher prediction quality of these models. This improves the understanding of the data needed for high quality machine learning models of injection molding processes and enable users to estimate a lower bound for the sample rates of time series for their use cases.","PeriodicalId":14410,"journal":{"name":"International Polymer Processing","volume":"38 1","pages":"167 - 174"},"PeriodicalIF":1.3,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47238065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermal stability and combustion performance of the MnPa-modified PUF (MnPUF) were investigated by using thermogravimetric (TG), thermal decomposition kinetics, smoke density characterization, limiting oxygen index (LOI) and UL-94 horizontal combustion test. The results indicated that the addition of MnPa significantly improved the thermal stability and combustion performance of the modified PUF. On the basis of the thermogravimetric analysis, Flynn-Wall-Ozawa method, Kissinger method and Coats Redfern method, it could be concluded that PUF with 7.5 wt% MnPa (MnPUF3) had the highest activation energy and the best thermal stability. Smoke density analysis, LOI and horizontal combustion analysis also showed that the addition of MnPa was positively correlated with smoke suppression, LOI value and burning time. The current research results can provide a reference for the subsequent flame retardant modification of PUF.","PeriodicalId":14410,"journal":{"name":"International Polymer Processing","volume":"38 1","pages":"300 - 309"},"PeriodicalIF":1.3,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47166621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
