“…According to Ohta [72], PE has the strongest ultimate strength among polymers, pointing the way for developing PE material properties, as shown in Table 1. Compared to conventional high-density polyethylene (HDPE), UHMWPE exhibits higher crystallinity and molecular weight, resulting in a highly oriented and nearly straight-chain crystal structure [74,75]. These characteristics contribute to its superior mechanical properties.…”

This review explores the use of Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber cloth as an innovative solution for the repair and reinforcement of concrete structures. UHMWPE is a polymer formed from a very large number of repeated ethylene (C2H4) units with higher molecular weight and long-chain crystallization than normal high-density polyethylene. With its superior tensile strength, elongation, and energy absorption capabilities, UHMWPE emerges as a promising alternative to traditional reinforcement materials like glass and carbon fibers. The paper reviews existing literature on fiber-reinforced polymer (FRP) applications in concrete repair in general, highlighting the unique benefits and potential of UHMWPE fiber cloth compared to other commonly used methods of strengthening concrete structures, such as enlarging concrete sections, near-surface embedded reinforcement, and externally bonded steel plate or other FRPs. Despite the scarcity of experimental data on UHMWPE for concrete repair, this review underscores its feasibility and calls for further research to fully harness its capabilities in civil engineering applications.

“…This nding is consistent with previous studies. 28,29,32 The main reason for this issue is the extremely slow diffusion of UHMWPE molecular chains. According to the reptation theory of de Gennes 33 and the tube model of Edwards, 34 the terminal relaxation time for a UHMWPE molecular chain (weighing about 10 6 g mol −1 ) is approximately 15 hours at 180 °C.…”

“…Therefore, HDPE is commonly used as a plasticizer and binder when blended with UHMWPE to improve its processability. Sui et al 28 melt blended UHMWPE with 50 wt% HDPE to promote the owability of UHMWPE melt. Yang et al 29 blended UHMWPE with 5 wt% HDPE and successfully pelletized the blends with a standard twin-screw extruded with a tapered die.…”

Polyolefins play a role in industries and are typically manufactured using two types of reactors: high-pressure tubular reactors and fluidized bed reactors. An innovative technology called the Multizone Circulating reactor (MZCR) has emerged, which introduces an innovative approach with interconnected polymerization zones creating a continuous loop of polymer flow. This study focuses on modeling and simulating ethylene gas phase polymerization within the MZCR in the presence of internal cooling to gain insights into its behavior. To achieve this, a comprehensive computational fluid dynamics (CFD) simulation was developed. It considered momentum, material, and energy balance aspects. The model equations were solved using the finite difference method in COMSOL Multiphysics version 6.1. The investigation primarily focused on studying the impact of incorporating a cooler into the riser section on the temperature profile within the reactor and ethylene conversion. The presence of this cooler resulted in a reduction in temperature change along the riser from approximately 8.0 °C to 4.0 °C. Moreover, it led to an increase of 7%, in ethylene single-pass conversion.
