This invention discloses a single-component moisture-curing conductive and thermally conductive adhesive and its preparation process, comprising the following raw materials in parts by weight: 100 parts SMP adhesive; 15-30 parts flake silver powder; 500-900 parts spherical silver-coated copper powder; 0-400 parts dendritic silver-coated copper powder; 10-20 parts decamethyltetrasiloxane; 1-1.5 parts β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate isooctyl ester; 7.5-10 parts N-β-(aminoethyl)-γ-aminopropyltrimethoxysilane; and 1-1.5 parts vinyltrimethoxysilane. This invention allows the adhesive to cure at room temperature / low temperature using moisture in the air, eliminating the need for temperatures above 120°C. This completely avoids thermal stress damage to heat-sensitive substrates such as plastics, flexible circuit boards, and PET / PI films, making it perfectly suited for low-temperature processing scenarios such as flexible electronics manufacturing, wearable devices, and flexible sensors.

This application discloses a trough fermentation system for lignite fermentation, including a fermentation trough and a heating device for heating the fermentation trough. A floor heating coil is installed at the bottom of the fermentation trough. The heating device supplies heat to the fermentation trough through the floor heating coil, providing different amounts of heat to the fermentation trough in the early, middle, and late stages of fermentation, respectively, so that the fermentation trough is in the first, second, and third stages. The gradient temperature control of this application can accurately meet the temperature requirements of different stages in the fermentation process, significantly improving fermentation efficiency, accelerating the fermentation process, significantly shortening the fermentation cycle, and reducing greenhouse gas emissions, thus offering environmental advantages.

This invention relates to the field of building waterproofing materials technology, and discloses a composition for a non-asphalt-based waterproofing adhesive, a non-asphalt-based waterproofing adhesive and its preparation method, a waterproof membrane, and its application. The composition consists of a main agent and additives. The main agent includes a rubber compound, petroleum resin, plasticizer, silanizing agent, and filler. Based on the total mass of the composition, the content of the rubber compound is 15-25 wt%, the content of the petroleum resin is 35-45 wt%, the content of the plasticizer is 10-15 wt%, the content of the silanizing agent is 0.5-2 wt%, and the content of the filler is 15-20 wt%. The rubber compound is a combination of liquid polysulfide rubber and liquid butyl rubber in a mass ratio of 1:2-3. The waterproof membrane provided by this invention has excellent adhesion, weather resistance, and waterproofing performance.

This invention discloses a multi-colored artistic paint that does not require multiple color particles for tinting and its preparation method, comprising the following steps: adding 50-70 parts by weight of modified base paint and 10-20 parts by weight of continuous phase to 20-30 parts by weight of protective colloid solution, dispersing at high speed until a set fine particle state is achieved, then adding 1-5 parts by weight of pigment, stirring at low speed until uniform, and discharging. This invention simplifies the process of separate tinting and group granulation of color particles, requiring only the production of one white paint product. Tinting can be directly performed on the finished paint, and it can be applied directly after tinting, displaying the effect of multiple color particles, with a strong texture, good feel, certain thickness and toughness, good crack resistance and scratch resistance, achieving free tinting, and ready for immediate use.

The utility model discloses a renewable cashmere air yarn, which belongs to the technical field of renewable cashmere yarns and comprises crocheting yarns formed by crocheting first yarns and at least one lining yarn inserted into the crocheting yarns along the longitudinal direction and formed by second yarns, the first yarn comprises core yarn and a wrapping fiber layer, and the wrapping fiber layer is made of renewable cashmere fibers. And the second yarns are low-extension yarns. According to the renewable cashmere air yarn, renewable cashmere fibers are adopted, and the environment-friendly effect is achieved. The crocheting yarn formed by crocheting can provide good bulkiness, and the used low-extension yarn can enable the air yarn to have good size stability in the length direction.
