The application discloses an environment-friendly and efficient degreasing process for a photovoltaic aluminum profile frame, and belongs to the technical field of aluminum degreasing, and specifically comprises the following steps: adding sodium carbonate and sodium bicarbonate into deionized water, and adding alkyl polyglycoside, low-foam surfactant, tetrasodium glutamate diacetate, sodium gluconate, reversible bridged polyamino acid salt, CO2 reversible interface migration microgel powder, tannic acid and defoaming agent into a reaction system. The application realizes efficient and environment-friendly degreasing of the photovoltaic aluminum profile frame through cooperation of weak alkali system, CO2 response functional components and reversible bridged polyamino acid salt, and maintains the oil removal rate and water contact angle after continuous operation for 100 hours, so that the stable degreasing effect is maintained, and the phosphorus-free environment-friendly performance is also possessed.

The invention provides high-permeability slurry for knitted fabric, a preparation method and a jet printing process. The high-permeability slurry of the knitted fabric comprises the following raw materials in parts by mass: 2-5 parts of sodium alginate; 1-5 parts of baking soda; 1 to 10 parts of urea; 2-10 parts of an alcohol ether modified penetrant; 1-5 parts of a film-forming agent; 0.1 to 2 parts of an antibacterial agent; 40 to 70 parts of deionized water; the alcohol ether modified penetrant with a ternary amphiphilic synergistic structure is designed, so that the alcohol ether modified penetrant has sulfonamide and siloxane chain segments which are equivalent to siloxane type permeable molecules with polar grippers, interface guide adsorption is formed, and slurry is helped to permeate inwards along fiber capillaries. The permeation, wetting and adhesion effects of a slurry system are improved.

This invention belongs to the technical field of thermal management and insulation materials for electronic and power equipment. Specifically, it discloses a controllable dense gradient boron nitride semi-cured thermally conductive and insulating film and its preparation method. This invention adopts a formulation-structure-process synergistic approach, in which multi-morphological hexagonal boron nitride (microspheres / sheets / nanotubes) after plasma activation and silane coupling treatment are hierarchically filled into a resin matrix, and then a multi-layer gradient structure film material is formed through controllable densification. This results in a film material that simultaneously possesses high thermal conductivity in the thickness direction, excellent electrical insulation, structural adhesion, and mass production processability. It is suitable for photovoltaic inverters, traction / auxiliary inverters for new energy vehicles, IGBT / SiC / GaN power modules, and interface thermal management and structural adhesion between PCBs and heat sinks.
