The present invention provides a chinlon spinning additive. The additive consists of the following components in parts by weight: 5 to 10 parts of zinc oxide, 3 to 5 parts of titanium dioxide, 2 to 6 parts of montmorillonite, 3 to 6 parts of vermiculite, and 1 to 3 parts of dispersing agent. The additive prepared in the present invention has a small grain size and good dispersing performance, and can improve the stability of spinning oil, ultraviolet prevention and antibacterial performance of the spinning oil after the additive is added into the spinning oil.

The invention discloses a sorting device realizing concentrated treatment of dismantling and draining for a dry powder can. The device comprises a bottom plate, four supporting legs, a first side plate, a second side plate, a front cover plate, a rear cover plate, a driving turnover unit, a dismantling and draining unit, a separating plate and a collecting hopper, wherein the four supporting legsare fixedly mounted at four corners of the bottom of the bottom plate in a symmetrically mode, and the first side plate and the second side plate are fixedly mounted on the two sides of the upper portion of the bottom plate correspondingly. According to the sorting device, the used dry power can can be treated without using manual operation, the working efficiency is effectively improved, and thethe working intensity is effectively reduced; the dismantled dry power can, dry power and water can be classified and collected for facilitating subsequent unified treatment; the residual quantity ofthe dry powder and water on the inner wall of the dry powder can can be effectively reduced, and the good treatment effect for the used dry power is achieved; and meanwhile, a prepared protective layer can prevent a large amount of residual dry powder and water being adhered to the inner surface of the collecting hopper, so that internal cleaning of the dry powder can is convenient, and cleaning can be carried out only by flushing with water.

The present invention relates to one kind of water-base lotus paint for inner and outer wall of building and its preparation process. The water-base lotus paint consists of dispersant, wetting agent, thickener, filming assistant, styrene-acrylic emulsion, antifreezing agent glycol, defoamer, bactericide, leveling agent, whitening agent and other ingredients. It is prepared through preparing pigment slurry, grinding and blending. It has the advantages of environment friendship, high adhesion, high wear resistance, etc.

Provided are a modified nanometer bamboo charcoal mask and a manufacturing method thereof. The modified nanometer bamboo charcoal mask comprises an inner mask and an outer mask, wherein the inner mask is provided with a dismounting opening, and a filer layer is arranged in the dismounting opening. The inner mask and the outer mask of the mask and a filer layer base plate are made of an electrets melt-blowing polypropylene fiber non-woven fabrics, the filer layer uses chitosan as a capsule wall material, microcapsules are made from modified nanometer bamboo charcoal powder, beewax is used as an adhesive for arranging the microcapsules on the non-woven fabrics. The modified nanometer bamboo charcoal powder are modified by adopting nanometer titanium dioxide. The modified nanometer bamboo charcoal mask is green, environment-friendly, safe and efficient, has the broad-spectrum antibacterial effect and has good washability due to the fact that the beewax is used as the adhesive to arrange the microcapsules on the non-woven fabrics.

The invention discloses a method for preparing moisture-absorbing, heat-generating and anti-bacteria yarn, which belongs to the technical field of yarn preparation. Firstly, polyacrylonitrile is modified by alkaline solution and soybean protein. The alkaline solution contains a large number of hydroxyl groups, so that water vapor molecules are adsorbed on the surface of the substrate, thereby improving the moisture absorption and heat generation performance of the yarn. In addition, these hydrophilic groups can make The polar force between polyacrylonitrile molecules is weakened, which is conducive to the improvement of the moisture absorption and heat generation performance of the yarn; the present invention utilizes the chitin in the crab shell to prepare chitosan through a fermentation method, thereby improving the solubility of chitosan, and in addition Adding chitosan in the matrix is ​​beneficial to improve the antibacterial properties of the yarn. In addition, the self-made chitosan is further modified with silver nitrate solution, and the generated hydroxyl radicals and active oxygen ions can destroy bacterial proliferation and achieve antibacterial. After the bacterial cell loses its activity, the silver ions are freed from the bacterial cell to achieve long-lasting antibacterial, thereby improving the antibacterial property of the yarn, and has a wide application prospect.
