20130225458 | HYDROPHOBIC PROPPANT AND PREPARATION METHOD THEREOF - The invention discloses a hydrophobic proppant and a preparation method thereof. The aggregate particles of the hydrophobic proppant are coated with a coating resin which comprises a hydrophobic resin and nano-particles which are uniformly distributed in the coating resin and constitute 5-60% of the coating resin by weight. The contact angle labeled as θ between water and the hydrophobic proppant in which nano-particles are added is in the range of 120°≦θ≦180°. The proppant of the present invention is prepared by adding the nano-particles in the existing resin in which low-surface-energy substances with hydrophobic groups are added, and a rough surface with a micro-nano structure is constructed on the outer surface of the prepared resin film, so that the contact angle θ at the solid-liquid contact surface on the outer surface of the coating resin of the proppant is more than 120°. | 08-29-2013 |
20130283685 | ANTI-PENETRATION AND GAS PERMEABLE POTTING CONTAINER, PREPARATION METHOD THEREOF, POTTING PLANTING CONTAINER AND POTTING - An anti-penetration and gas permeable potting container and preparation method thereof are disclosed. The anti-penetration and gas permeable potting container is made by bonding aggregate particles with hydrophobic binder, and pores which allow gas molecules to penetrate and liquid water molecules not to penetrate are formed between adjacent aggregate particles. Further, a potting planting container applying said potting container is disclosed, wherein it includes a cultivating layer, and a base anti-penetration layer formed of waterproof and gas permeable particles which is provided between the potting container and the bottom of the cultivating layer. Pores which allow gas molecules to penetrate and liquid water molecules not to penetrate are formed between adjacent waterproof and gas permeable particles. Said pores are thoroughly distributed on the base anti-penetration layer. The container can prevent water from flowing from its bottom, and has gas permeable property. | 10-31-2013 |

20140014565 | OIL-WATER SEPARATING DEVICE AND FLOATING OIL COLLECTING SYSTEM COMPRISING SAME - The present invention provides an oil-water separating device and a floating oil collecting system. The device comprises an oil gathering chamber ( | 01-16-2014 |
20150108053 | Water Purification and Storage System, Water-Filtering Well and Polygonal Building Block - A water purification and storage system comprises a water storage container, a covering plate and an impermeable wall. The water storage container is formed by a plurality of tangentially connected polygonal water-filtering wells having well walls of a water-permeable structure, and an impermeable layer is arranged at the bottom of the well. At least one water-filtering well is a water output well. The covering plate is arranged at the upper portion of the water storage container, and comprises an impermeable covering plate arranged at the upper portion of the water output well and a water-permeable covering plates arranged at the upper portions of the remaining water-filtering wells. The impermeable wall is arranged around the water storage container. The system is suitable for the collection and purification of rain water. Also disclosed are a water-filtering well for use in the system, and a polygonal building block for the water-filtering well. | 04-23-2015 |
