Preparation and characteristic of self-regulation water-transmitting coating fiber

Abstract

Common clay, Kaolin and Bentonite were used as additives to prepare water-transmitting coating fiber, respectively, and the water-transmitting characteristic of coating fiber was studied. Different water-transmitting coating fibers were prepared by coating fiber using coating material with different mass proportions of additives to adhesive. And the coating materials were made from three kinds of inorganic clays as additives respectively and polyvinyl alcohol (PVA) as adhesive. Furthermore, the surface morphology and water-transmitting capacity of coating fiber were studied by SEM, Perkin Elmer Diamond SⅡthermal multi-analyzer and instrument for quick measurement moisture M30. The experimental results indicate that water-transmitting coating fibers made from three kinds of clays all have water-transmitting capacity. The surface of water-transmitting coating fiber prepared by common clay T is continuous and compact, and the water-transmitting effect is better than coating fibers made from other clays.

Toluene adsorption on porous Cu–BDC@OAC composite at various operating conditions: optimization by response surface methodology

“…The presence of the upli curve at diameter < 2.5 nm for Cu-BDC@OAC proves the existence of micropore structure. 48 Also, the BET surface areas and different textural parameters of the samples are listed in Table 2. From this table, it can be found that introducing Cu-BDC MOF to OAC caused a signicant effect on the textural features (Cu-BDC@OAC).…”

“…The current results showed that the volume of micropores was an important factor for the removal of VOCs and are consistent with those reported in the literature. 48,51,52 Based on the theory of volume lling of micropores, adsorption is increased because of the overlap of dispersion forces from adjacent pore walls. 51 The effects of different operational parameters for adsorption of toluene on the composite were studied separately.…”

Experimental study on interaction between wettability configuration and dewing efficiency of surfaces with a cavity array

“…Relative humidities provided for both the previous and current studies are no match for those in desertification areas. According to the data collected in Northwest China by our research group, although the ambient temperature (annual 293 K) is close to the temperature in our dewing chamber, the annual relative humidity in those regions is below 10%, 6–8 which is very different to test chambers.…”

“…With the help of this irrigation system, we have implemented large-scale planting of Haloxylon ammodendron and Nitraria tangutorum in Minqin County (Northwest China) and Abu Dhabi desert (Western United Arab Emirates). Between 2005 to 2015, particularly in Minqin, a high survival rate of plants and a minimal amount of offsite water input has been achieved 6–8 (Fig. 1(b)–(d)).…”

Enhanced toluene adsorption/desorption dynamic performances over modified USY zeolites after an aqueous ammonia treatment

“…[9][10][11] Taking into consideration both the functionality and the cost, USY (ultra-stable Y) zeolites are highly dealuminated with a stable siliceous 12-membered ring framework, which has been proved to have a great affinity towards various VOCs. 12 However, the complete desorption temperature of Y zeolites was reported over 350 C for toluene, 13 which could be attributed to the diffusion limitation due to the high proportion of microspores. This would result in the inhibition of its real application.…”
