The invention discloses a breathable film type lithium ion battery electrolyte standard leakage device, and relates to the field of lithium ion batteries. The leakage mark comprises a leakage mark body and a breathable film, and a liquid storage cavity is formed in the leakage mark body; a vent hole is formed in the leakage mark body, and the liquid storage cavity is communicated with the outside of the leakage mark body through the vent hole; the breathable film is mounted in the breathable opening; the gas-permeable membrane is of a layered structure and comprises a high-strength supporting layer and an organic gas diffusion layer; the organic gas diffusion layer permeates into the high-strength supporting layer to form a permeation composite layer, and the thickness of the permeation composite layer accounts for 0%-100% of the thickness of the high-strength supporting layer. The device is simple and reliable in structure, electrolyte can be adopted as a calibration object, the current stabilization effect is achieved through the breathable film, electrolyte gas can overflow at a stable rate, and the accuracy and reliability of calibration, calibration and spot inspection of existing liquid leakage detection equipment are improved.

The utility model discloses a volatilization structure for an electric mosquito-repellent incense liquid bottle, which comprises a core rod and a lantern ring, the lantern ring is sleeved on the lower portion of the core rod, a fixing part is arranged at the lower end of the lantern ring, a soft absorption sheet is fixedly arranged on the inner side of the fixing part, and the upper portion of the soft absorption sheet is tightly attached to the lower surface of the core rod. And the lower part of the soft absorption sheet is freely attached to the bottom of the inner side of the mosquito-repellent incense liquid bottle. The soft absorption piece is fixedly arranged on the inner side of the fixing part, the upper portion of the soft absorption piece is tightly attached to the surface of the lower portion of the core rod, the lower portion of the soft absorption piece is freely attached to the bottom of the inner side of the mosquito-repellent incense liquid bottle, under the condition that the amount of the mosquito-repellent incense liquid is small, the mosquito-repellent incense liquid can make full contact with the mosquito-repellent incense liquid, and then the mosquito-repellent incense liquid is transmitted to the core rod. The mosquito-repellent incense liquid can be stably volatilized, and the stable and good mosquito killing effect is guaranteed.

The invention relates to the technical field of electronic cigarettes, and discloses an electronic cigarette essence sheet based on efficient environment-friendly low-temperature polymer volatilization and a manufacturing process thereof.The essence sheet comprises a composite material with polylactic acid as a matrix, and modification of the polylactic acid comprises compounding with aluminum oxide nanoparticles so as to improve the thermal stability of the polylactic acid; the composite material further comprises essential oil in a certain proportion, and the essential oil is used for volatilizing at a controlled rate and under a low-temperature condition in the heating process by being combined with a specific chemical bond of polylactic acid; the volume fraction of the aluminum oxide nanoparticles is accurately controlled to be 5%, and more uniform heat distribution is realized by enhancing the heat conductivity of the composite material, so that the volatile performance of the essence is optimized. The aluminum oxide nanoparticles are introduced into a polylactic acid matrix, so that compared with a pure polylactic acid material, the heat conductivity coefficient is increased by about 3 times, and the problem of local overheating or non-uniform essence volatilization caused by poor heat conduction of a traditional essence tablet is solved.

This invention relates to a salt spray resistant and anti-aging curing coating and its preparation method, belonging to the field of coating technology. The coating includes modified epoxy resin, ternary nanocomposite filler, composite light stabilizer, hydrophobic eutectic solvent, polysiloxane-modified aromatic amine curing agent, and bio-based polyurethane curing agent. The modified epoxy resin is prepared by reacting bisphenol F epoxy resin, KH-560 silane coupling agent, and tetrabutylammonium bromide, followed by the addition of bi-terminated epoxy silicone oil, 3,3'-dithiodipropionic acid, and p-toluenesulfonic acid, and then by adding pentaerythritol phosphate and antioxidant 1010. The polysiloxane-modified aromatic amine curing agent is prepared by reacting m-phenylenediamine as a matrix, KH-560 silane coupling agent, diphenylsilanediol, and dibutyltin dilaurate. The bio-based polyurethane curing agent is prepared by reacting castor oil-modified polyol, isophorone diisocyanate, dibutyltin dilaurate, dimethylolpropionic acid, and trimethylolpropane.
