In recent years, super oleophobic-superhydrophilic materials have been favored in oil-water separation due to their special wettability. Because the surface tension of oil is much smaller than that of water, the superoleophobic-superhydrophilic surface is more difficult to prepare and the superoleophobic surface is mostly superhydrophobic, which limits its application in oil-water separation. In addition, the surfactant-stabilized emulsified oil droplets have a small particle size (<10 μm) and high stability, and require a complicated demulsification process to achieve oil-water separation. Therefore, there is an urgent need for a simple, efficient and environment-friendly oil-water separation material for the purification of oily wastewater.
Scientists Zeng Zhixiang, Wang Gang, and He Yi of the Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences prepared surface nanopores and matrix macroporous cellulose sponges for the separation of surface activity by means of the dissolution and regeneration of cellulose and the occupation of pore formers. A stable oil-water emulsion. This sponge does not need to be chemically modified to have the special wettability of oleophilic, hydrophilic, super-oleophobic underwater. In the acid, alkali, and salt solutions, the contact angles of various oils are all greater than 150° and the superoleophobic properties are stable. The nanopores in the surface layer of the sponge can effectively prevent the penetration of small-size emulsified oil particles. The macroporous structure of the matrix and its super-hydrophilicity can ensure that the aqueous phase quickly passes through the sponge matrix and achieve oil-water separation. The prepared cellulose sponge showed high oil-water separation efficiency (>99.94%), water flux (91 Lm −2 h −1 under gravity), oil penetration resistance (supported 22 cm) in separation of oil-water emulsions. Chlorine liquid column) and other characteristics. In addition, the cellulose sponge has a self-cleaning ability, can effectively prevent the contamination of oil contaminants, and has high reusability.

Aluminium and steel Clothes Rods
Modern people's home life pursues fashion and simplicity. Clothes are mostly stored by hanging, which can not only keep the clothes bright, flat and wrinkle free, but also be selected at will and convenient for storage. Therefore, the hanging area has become the most important part of modern wardrobe. The core component of the hanging area is the clothes hanging rod, but there are many mysteries in a small clothes hanging rod.walk in closet organizer systems,Aluminium Wardrobe Tube,large closet system,clothes hanging poles,Clothes Rods.
Many brands of wardrobes are now known as "freely adjustable laminate, heart DIY", but in fact, "freely adjustable laminate" can be realized, but "heart DIY" is difficult to achieve. Because most brands of clothes hanging rods are fixedly installed on the side plate of the wardrobe, after adjusting the laminate, the clothes hanging rod cannot be adjusted freely. If forced adjustment, there is no doubt that two ugly holes will be left on the side plates on both sides, affecting the beauty of the wardrobe.
Therefore, if you want to truly "follow DIY" without wasting space, you can only install the clothes hanging rod on the laminate. When adjusting the laminate, the clothes hanging rod will change with the height of the laminate, the height of the clothes hanging space can be controlled freely, and will not cause any damage to the side plate. You can really follow your inclinations.
The hanging rods of all wardrobe products are installed on the laminate, fully considering the practicability of the wardrobe. Users can adjust the height of the laminate according to their preferences, so as to set their favorite hanging space, and truly realize the humanized "DIY". Moreover, considering that the clothes hanging rod is used to hang clothes, the load-bearing capacity is very important. It is easy to customize. The high-quality and solid aluminum alloy is used as the material of the clothes hanging rod to ensure its load-bearing capacity, and the anti-skid treatment is made on the clothes hanging rod, which is considerate and thoughtful.
