This utility model relates to the field of lining production technology and discloses a warp beam dyeing vat anti-expansion clamp, including a fabric roll body, an anti-expansion clamp surrounding the end of the fabric roll body away from the center line, warp beam barrels at both ends of the fabric roll body, and the anti-expansion clamp consisting of side baffles, upper outer clamps, and lower outer clamps. An outer baffle and an inner baffle are fixedly installed on the end of the side baffle near the warp beam barrel. This warp beam dyeing vat anti-expansion clamp attaches four upper and lower outer clamps to the upper and lower sides of the fabric roll body, respectively. The stainless steel material ensures the clamps have sufficient strength to withstand the pressure generated during the dyeing process. The "arc" structure fits snugly against the fabric roll body, tightly wrapping the fabric roll. During the dyeing process, especially for elastic fabrics, it effectively limits the expansion of the fabric roll, preventing it from sagging due to expansion and avoiding loss of elasticity. It can also be adjusted according to the diameter and width of the dyed fabric roll.

The utility model provides a compression-resistant core model profile pipe, which relates to the technical field of lightweight walls, and comprises two groups of inner templates, the two groups of inner templates are spliced to form the compression-resistant core model profile pipe, and a plurality of groups of mutually independent cavities are arranged in the core model profile pipe; each inner template comprises a plurality of groups of convex parts which are transversely arranged, the convex parts of the two inner templates are spliced to form a cavity, lug plates are fixed on the two sides of each convex part, and the adjacent convex parts are fixedly connected through the lug plates. And a plurality of groups of cavities are formed in the shell. On one hand, concrete consumption can be reduced, self-weight is effectively reduced, and building load is reduced; on the other hand, the cavity forms an air layer, heat transfer can be remarkably reduced, and efficient heat preservation and heat insulation are achieved. Meanwhile, the effect of blocking sound wave conduction can also be achieved.

The invention belongs to the technical field of nickel-based wrought superalloy heat treatment, and particularly relates to a heat treatment method for improving the durability of a GH4169G alloy and application. A to-be-treated bar is pretreated at the temperature of 1000-1020 DEG C, heat preservation is conducted for 10-90 min, and then water cooling is conducted; the treated bar is further subjected to solution treatment at the temperature of 960-990 DEG C, and air cooling is carried out after heat preservation is carried out for 50-70 min; and the treated bar is further subjected to two-stage aging treatment, and then the required bar is obtained. Delta phases in crystal grains in the bar can be effectively reduced through pretreatment, and subsequent precipitation of sufficient gamma'strengthening phases after aging treatment is promoted; meanwhile, solid solution treatment promotes precipitation of a proper delta phase on the bar grain boundary, and it is guaranteed that the bar grain boundary has certain strength; in conclusion, after treatment through the heat treatment method, it is guaranteed that sufficient gamma'strengthening phases are separated out in bar crystals and appropriate delta phases are separated out in the grain boundary, and finally the excellent durability of the bar is guaranteed.

The invention discloses a modified epoxy curing agent based on KH-560 distillation residues as well as a preparation method and application of the modified epoxy curing agent. The preparation method comprises the following steps: A, putting a polyamine compound into a stirring kettle, and stirring; b, putting an accelerant into a stirring kettle, stirring the accelerant and the polyamine compound to obtain a mixed solution, uniformly mixing, introducing nitrogen into the stirring kettle, and replacing air in the kettle; c, the KH-560 distillation residues are put into a storage tank, nitrogen is introduced into the storage tank, and air in the storage tank is replaced; d, heating the mixed solution in the stirring kettle to a reaction temperature, and metering and dropwise adding the KH-560 distillation residue into the stirring kettle according to a theoretical equivalent to react; e, after dropwise adding is completed, liquid in the stirring kettle is subjected to heat preservation and continuous stirring at the reaction temperature, and the modified epoxy curing agent is obtained after discharging. According to the scheme, the KH-560 distillation residue can be safely and efficiently converted into the modified epoxy curing agent, the epoxy value in the KH-560 distillation residue is recycled, and meanwhile, the environment-friendly treatment cost is reduced.
