Study Of Rubber Growth Under Constraint of Pyrite In Tidal Swampy Area

Journal of Wetlands Environmental Management, 2017
Muara Sugihan is one of the tidal swamp areas for rubber plant cultivation in South Sumatera. A preliminary survey of the land suitability in 2012 described that there are two main problems, the shallow groundwater problem and low pH (2,87-3,05) between ...

Rubber friction: role of the flash temperature [PDF]

, 2006
When a rubber block is sliding on a hard rough substrate, the substrate asperities will exert time-dependent deformations of the rubber surface resulting in viscoelastic energy dissipation in the rubber, which gives a contribution to the sliding friction.

The role of thermodynamics and kinetics in rubber–bitumen systems: a theoretical overview

International Journal of Pavement Engineering, 2020
Waste tire rubber has been incorporated into asphalt modification for decades due to its various benefits. There are two main mechanisms during bitumen–rubber interaction: rubber swelling and chemical degradation.

Rubber, rubber and rubber: How 75 years of successive rubber plantation rotations affect topsoil quality?

Land Degradation & Development, 2022
AbstractRubber tree plantations (Hevea brasiliensis) cover large areas in the tropics. In historical producing regions like South Thailand, rubber has been planted by smallholders for three successive rotations lasting a total of 75 years. Despite possible consequences on topsoil, the long‐term impacts of repeated rubber plantations on soil quality ...

Influence of Temperature on Scratch and Wear Properties of Technical Thermoplastics: Implications for Material Selection

Advanced Engineering Materials, EarlyView.
The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of
