The recycling process is the best way to manage waste polymers. From an economic standpoint, more investigation needed of whole enhance competitiveness in these systems. A first step improved interaction and interfacial adhesion blends. Polyethylene (PE) polyethylene terephthalate (PET) are incompatible polymers, so their blends general have poor properties. Compatibilization thus a necessary o...

Rations containing approximately 85% ground high-moisture, ensiled corn were fed to steers in such a way as to produce lactic acid acidosis, and three dietary buffers were evaluated in regard to their effect on ruminal and systemic acidosis. The buffers consisted of (1) 2% sodium bentonite, (2) 1% sodium bentonite plus 1% dolomitic limestone, and (3) 1% sodium bentonite plus 1% potassium bicarb...

Methylglucoside (MEG) has been used in the water-based mud with fine montmorillonite (MMT) swelling inhibition, but it still has such shortages as large concentration and low thermostability. In this work, carboxymethyl glucoside (CMG) was synthesized with glucose and sodium chloroacetate and used as swelling inhibitor. The inhibition of CMG against clay swelling was investigated by MMT linear ...

We assess the morphological stability of a non-equilibrium ice–colloidal suspension interface, and apply the theory to bentonite clay. An experimentally convenient scaling is employed that takes advantage of the vanishing segregation coefficient at low freezing velocities, and when anisotropic kinetic effects are included, the interface is shown to be unstable to travelling waves. The potential...

Bentonite mixed soil, which is a mixture of bentonite with sand and gravel, can be easily compacted by adjusting the blending degree, it difficult for water to pass through exhibits low permeability. It widely used at construction sites because on-site has good workability. Examples its use include impermeable layers waste disposal measures contain heavy metals from rocks generated sites. The m...

In this study, nanocomposite hydrogels of poly(methacrylic acid-co-acrylamide) (Poly(MAA-co-AAm)) containing different weight percent bentonite clay nanoparticles (0, 5, 10, and 15 wt. %) were used to remove methyl violet (MV) dye. FTIR, SEM, TGA, XRD analyze the properties adsorbents. Results showed that successfully distributed in hydrogel system. Bentonite at 10 % gave maximum MV dye adsorpt...

The performance assessment of a geological repository for radioactive waste requires quantifying the geochemical evolution of the bentonite engineered barrier. This barrier will be exposed to coupled thermal (T), hydrodynamic (H), mechanical (M) and chemical (C) processes. This paper presents a coupled THC model of the FEBEX (Full-scale Engineered Barrier EXperiment) in situ test which accounts...

Bentonite is a key barrier for the isolation of high-level radioactive waste within Deep Geological Repository. However, bentonite may be altered by contact with cementitious materials and their alkaline pore fluids. This study offers an extensive morphological semi-quantitative characterization surface exposed to three types fluids released different cement-based materials. The surfaces were s...
