4results about How to "Maintain bond strength" patented technology

The application belongs to the technical field of sand consolidation agent preparation, and particularly relates to a sand consolidation agent and a preparation method thereof. The sand consolidation agent is composed of component A and component B. The component A is composed of the following raw materials: a diphenyl phenolic epoxy resin, hexakis(4-hydroxymethylphenoxy)cyclotriphosphazene, modified nano calcium zirconate, cage octakis(aminophenyl)silsesquioxane, n-butyl glycidyl ether, KH-550 silane coupling agent, polyether amine, fumed silica and defoaming agent. The component B is composed of the following raw materials: polyborosilazane and 2-ethyl-4-methyl imidazole. The cage octakis(aminophenyl)silsesquioxane in the raw material of the sand consolidation agent strengthens the network structure stability through chemical bonding, the hexakis(4-hydroxymethylphenoxy)cyclotriphosphazene realizes thermal stabilization through chemical bonding and physical dispersion, and the modified nano calcium zirconate provides physical support. The three components synergistically improve the heat resistance of the system.

The application relates to the technical field of chemical raw material storage and mixing, and discloses a kaolin stirring and storing system for producing paper tube glue, which comprises a tank body, a multi-channel self-adaptive jet flow module, an acoustic sensing and suspension dual-mode array module and an intelligent collaborative control module. The acoustic module uses the ultrasonic principle to detect the concentration distribution and the velocity field of the kaolin in the tank in real time and non-destructively. The intelligent collaborative control module analyzes and identifies potential settlement areas based on the detection data, and cooperatively controls the multi-channel self-adaptive jet flow module to perform targeted jet flow and controls the acoustic sensing and suspension dual-mode array module to perform non-contact suspension intervention by using focused acoustic energy according to the severity of the settlement. The application forms a closed-loop adaptive control of sensing decision hierarchical execution, effectively prevents hard cake formation, guarantees long-term uniformity and stability of the glue solution, and improves product quality and automation level.

The invention belongs to the technical field of sand consolidation agent preparation, and particularly relates to a sand consolidation agent and a preparation method thereof. The sand consolidation agent is composed of a component A and a component B, the component A is prepared from the following raw materials: biphenyl novolac epoxy resin, hexa (4-hydroxymethyl phenoxy) cyclotriphosphazene, modified nano calcium zirconate, cage-shaped octa (aminophenyl) silsesquioxane, n-butyl glycidyl ether, a KH-550 silane coupling agent, polyether amine, fumed silica and a de-foaming agent; the component B is prepared from the following raw materials: polyborosilazane and 2-ethyl-4-methylimidazole. Cage-shaped octa (aminophenyl) silsesquioxane in raw materials of the sand consolidation agent strengthens the stability of a network structure through chemical bonding, hexa (4-hydroxymethylphenoxy) cyclotriphosphazene achieves thermal stabilization through chemical bonding and physical dispersion, and modified nano calcium zirconate plays a physical support role. The three synergistically improve the heat resistance of the system.

The application discloses a cutting and welding integrated device and method for a building steel decorative plate; the application sprays active alloy powder to a welding edge position to strip burr surface oxide scales and embed the powder to form a to-be-welded active layer; the active alloy powder is used to remove the burr surface oxide scales by using powder spraying kinetic energy to expose pure metal and embed the powder in the welding edge position to form a to-be-welded active layer with gradient distribution; in arc discharge, the burr tip forms a stable arc striking channel to avoid arc running away and cause the thin decorative plate to be burnt through; the embedded powder absorbs excess heat energy by phase change latent heat in the molten pool formed by layer-by-layer melting, thereby reducing the polishing process, and the burrs originally belonging to processing waste are converted into self-melting filler; meanwhile, the internal slag inclusion and opening layering defects in the splicing of dissimilar metal composite plates are radically solved, and the welding firmness between the steel decorative plates is improved.
