How do you mold the rubber in to a shoe ,older?4 answersRubber shoe molding processes involve several steps. First, the raw material is processed to obtain primary male and female molds, which are then ground and drilled to create secondary molds. These secondary molds undergo trimming, deflashing, and paint spraying to obtain finished molds. The rubber is vulcanized to produce finished rubber. Finally, compression molding is performed using the finished molds to obtain the rubber shoe sole. Another method involves using a mold assembly with left and right mold boxes, which are locked using mechanisms. A shoe rubber foaming and molding machine consists of a pedestal, mold clamping device, last inversing device, and last, providing a simple and efficient structure. Additionally, rubber shoes can be molded using a process that involves mixing ingredients, heating, charging into a metal mold, cooling, and drying. Another method uses SBS as the main raw material and involves liquefaction, filling and pressing, cooling, finishing, and drying.
What are the implications of the global rubber industry for the global economy?4 answersThe global rubber industry has significant implications for the global economy. The increasing demand for natural rubber has led to the expansion of rubber plantations, often at the expense of agricultural land for staple crops. This competition between rubber production and food systems affects the livelihoods of rural communities and their access to natural resources such as water. Additionally, sector-specific policies in the rubber industry can have spill-over effects on other sectors and countries, impacting price relations and market dynamics. The economic life-cycle of rubber trees and the cost of production also play a role in the industry's impact on the global economy. Furthermore, the rise of the circular economy and digital transition in the plastics industry, which includes synthetic rubber, brings structural and workforce changes that require adaptation and skills hybridization. Overall, the global rubber industry has environmental, social, and economic implications that affect various aspects of the global economy.
What is the competitive landscape of the rubber industry?4 answersRubber exporting countries such as Thailand, Indonesia, and Malaysia have strong competitiveness in the global market for natural rubber commodities. Indonesia ranks second after Vietnam for competitiveness in the ASEAN market. The expansion of rubber plantations in Southeast Asia could lead to significant environmental consequences. Mexico's states of Tabasco, Veracruz, Chiapas, and Oaxaca have competitive advantages in natural rubber production. The rubber industry in Indonesia during 2009 had an oligopoly marketing structure.
What are the environmental impacts of the rubber industry?5 answersThe rubber industry has significant environmental impacts. Rubber production requires large amounts of fertile land and freshwater, leading to competition with food systems and affecting rural communities' livelihoods and water resources. Rubber plantations have been found to cause deforestation, with higher rates than previously estimated, resulting in biodiversity loss and impacts on ecosystem services. The use of water, energy, and chemicals in natural rubber processing also contributes to environmental pollution. Rubber plantations in Xishuangbanna Region have led to a decrease in biodiversity, weak soil and water conservation, reduction of soil nutrients, and increased pest and disease outbreaks. These negative impacts highlight the need for strategies such as material substitution, wastewater reuse, and good housekeeping to prevent pollution in the rubber industry. Overall, the rubber industry's environmental impacts include pollution, deforestation, biodiversity loss, and competition for resources.

Is silicone rubber soluble in deep eutectic solvent ?
4 answers
Silicone rubber can be soluble in certain solvents. While deep eutectic solvents (DESs) have been primarily studied for their interaction with silica-filled rubber composites, other solvents have also been explored for silicone rubber. For instance, an organic solvent with specific solubility parameters and boiling points has been used to reduce low-molecular siloxanes in silicone rubber products. Additionally, a solvent designed for dissolving silicone is described to contain specific solvents that enhance silicone solubility. Therefore, while deep eutectic solvents have shown promise in enhancing the properties of rubber composites, other solvents tailored for silicone dissolution may be more suitable for silicone rubber solubility.
What factors contribute to the increase in modulus but decrease in strength observed in fibre reinforced polymers?
4 answers
The increase in modulus but decrease in strength observed in fiber-reinforced polymers (FRP) can be attributed to various factors. Firstly, the arrangement, length, and orientation of fibers impact the modulus and strength. Additionally, interfacial debonding, poor adhesion between fibers and matrix, and the presence of voids can lead to a decrease in strength. Moreover, the thermal behavior of FRP under elevated temperatures can alter the failure mode from brittle to ductile, affecting both modulus and strength. Furthermore, the addition of reinforcing layers in elastomers can increase modulus but decrease strength due to reduced elongation and abrasion resistance. These factors collectively influence the mechanical properties of FRP, showcasing a complex interplay between reinforcement, matrix, and environmental conditions.
What is the compressiveness of rubber?
5 answers
The compressive behavior of rubber varies depending on its composition and context. Research indicates that incorporating rubber into concrete can enhance compressive strength, with improvements observed in rubberized concrete compared to traditional concrete due to better interfacial transition zones. Additionally, studies on granulated rubber-loess mixtures show increased compressibility with higher rubber content, making them suitable as lightweight fill materials in civil engineering applications. However, the compressive strength of rubber concrete tends to decrease as the rubber content increases, impacting its tenacity and resistance to cracking. Simulation studies also demonstrate a decrease in compressive strength with higher rubber percentages, leading to increased displacements and deformations due to stress concentration in the rubber components.

Additionally, a coupled fluid-poroelastic model was developed to study seismic attenuation induced by fluid pressure diffusion in porous rocks with mesoscopic voids, highlighting the importance of voids in modeling viscoelastic properties in geological materials.
What factors influence the ultimate tensile strength of rubber?
4 answers
The ultimate tensile strength of rubber is influenced by various factors. These include the tensile strength of individual polymer load-bearing chains according to Eyring's theory, an occupation number of load-bearing chain states using Fermi statistics, and an excluded volume factor due to filler particles or crosslinks between polymers. Additionally, the finite extensibility of chain segments between network points, strain-induced crystallization, and molecular flexibility play crucial roles in achieving high tensile strength at high strain at break. Furthermore, the interaction between active filler surfaces and macromolecules can lead to the transition of the rubber matrix to a pseudoglassy state, affecting the tensile strength and breaking elongation of rubber. These factors collectively contribute to determining the ultimate tensile strength of rubber.
