The effects of bentonite on the pore structure of cement mortar were given It is evident from the comparison that the improvement in the water resistance can be attributed mainly to bentonite and how the bentonite inhibits the movement of water in cement mortar would be elaborated in the next section Effect of polymer modified
Compared with KH560 Bentonite and ODBA Bentonite DC5700 Bentonite could better enhance the thermal stability and high temperature deformation resistance of SMB as well as had less adverse effects on the low temperature ductility and low temperature cracking resistance of SMB which was due to the fact that synchronous surface grafting and
Porcelain enamel is an inorganic type coating which is applied to metals or glass for both decorative and functional purposes This coating is a silica based solidified glass mass obtained by
The results showed that the increase of cement content was negatively related to the thixotropy of epoxy coating but it promoted the tensile strength of the coating On the contrary bentonite had a positive effect on the thixotropy of the coating and a negative effect on the tensile strength of the coating
The clay mineral bentonite has received a lot of attention for its potential to reduce the harmful effects of drought on soil health and biological activity
Impedance modulus value reached × 10 8 Ω cm 2 of silica based so gel coating with 1/9 wt% of ZrO 2 and thickness of 25 μ Adding wt% corrosion inhibitor Ce 3 loaded in bentonite in the coating effectively delayed corrosion of carbon The hydrophobic top layer increased the water contact angle from 89° to 115°
The effect of water content normal stress and rough surface on the relationship between shear stress and shear displacement of clay concrete interface was analysed by Shakir and Zhu [8] For studying the effect of bentonite on frictional resistance at pile soil interface Effect of Bentonite Support Fluid on Pile Capacity 617 different
Bentonite is a kind of widely distributed clay that contains montmorillonite MMT mainly The typical chemical structure of montmorillonite consists of an edge shared octahedral sheet with aluminum or magnesium hydroxide and two tetrahedral silicate sheets with sodium or calcium cations which can be chemically replaced by a cationic exchange reaction
The effect of drying temperature on water vapor transmission rate WVTR and water contact angle of coated paper was further investigated using wt% chitosan and 96% beeswax solid content in
The utilized bentonite originated from the natural organic bentonite clay of the Al Azraq region in East Jordan The mass specific gravity for particles passing sieve No 200 size mm stood at accompanied by a total gross surface area of 420 m 2 /g and a water absorption rate of 190 To explore mineral characteristics X ray diffraction
The coated paper demonstrated excellent oil resistance with a kit rating of 11/12 and outstanding water resistance with a water contact angle of ° and water absorption of %
Superhydrophobic nanocomposite coatings prepared using adhesive and fillers offer advantages including ease of fabrication and suitability for large scale applications but compared with other types of artificial superhydrophobic surfaces poor durability still limits these surfaces from practical applications The utilization of micro/nanoscale particles with both
The coatings displayed desired transparency hydrophobicity water vapour permeability thermal resistance repulpability and compostability This highly stable surfactant free beeswax AELO emulsion could establish a safe green and sustainable water resistant coating for compostable paper packaging while supporting the circular economy

The effects of multiwalled carbon nanotubes MWCNTs on the adhesion strength and corrosion resistance of the acrylic nanocomposite coatings were evaluated on Q235 substrates via pull off tests
SiC particles various rate of bentonite powders and certain amount of water has been mixed to prepare ceramic slurry Bentonite consisting of a high calcium concentration has been mixed with SiC particles This is a non swelling bentonite that offers substantially lower dry and hot strengths by comparison to sodium bentonite
Crushed high density bentonite pellet mixtures have been proposed to fill the construction gaps of the high level radioactive nuclear waste repository Compared with compacted bentonite block the thermal conductivity of bentonite pellet mixture is relatively low which can cause a significant increase in the peak temperature of the buffer layer In this

The influence of parameters such as volumetric water content dry density void ratio bentonite content and temperature on electrical resistivity values are also studied View Show abstract
Nanoclay has proven to be an active anti corrosive additive due to the self repairing effect from nanoclay swelling and expansion except for its passive barrier effect due to the high aspect ratio But it is still uncertain how these effects of nanoclay are intertwined with the other components in a complex coating system in corrosive environments In this study we
Ultraviolet UV curable films find increasing applications in coating industries because of their rapid cure solvent free characteristics application versatility low energy requirements and low temperature operation [1] Depending on the final application it is desirable to formulate polymer film systems with low shrinkage high flexibility decreased viscosity
Presently about 200 million tons of urea fertilizer is produced worldwide to meet supply and demand However a quarter of the urea applied to soils is lost to the environment due to poor efficiency
