  • Publication number: 20220305703
    Abstract: A foaming and dyeing integrated production method for a polymer material product includes steps of putting a polymer material preform into a foaming and dyeing kettle, and loading dye into a dyeing circulation module; gasifying CO2 and injecting the CO2 into the foaming and dyeing kettle, stopping pressurization when the CO2 reaches a supercritical state; performing a dyeing circulation process in which the CO2 in the supercritical state enters the dyeing circulation module and dissolves the dye in the dyeing circulation module, when the dyeing process is finished, injecting CO2 and/or N2 pressurized in the fluid pressurization delivery module and heated in the fluid heating module into the foaming and dyeing kettle, stopping pressurization and starting foaming operation when requirements of a foaming process are met; and when the foaming process is finished, taking out a foamed and dyed polymer material product in the foaming and dyeing kettle.

  • Patent number: 11413592
    Abstract: The invention discloses a horizontal supercritical fluid foaming autoclave with an internal stirring device, comprising a horizontal autoclave body, an end cover, a stirring driver and a stirring paddle, wherein a stirring shaft of the stirring driver passes through the autoclave body and is connected with the stirring paddle positioned inside the autoclave body. The stirring driver of the invention can drive the stirring paddle to rotate, drive the fluid in the autoclave body to generate convection circulation, increase convection heat transfer, improve a uniform distribution degree of the temperature in the autoclave, enable the temperature in each position in the autoclave body to be consistent, ensure the consistency of the shape and parameters of foamed products, and improve the yield of the products.

  • Publication number: 20220252936
    Abstract: A display panel, a display module, and a display device are provided. The display panel includes a total reflection display unit and a frame enclosing the reflective display unit. The frame includes a light-shielding portion and a reflective layer. The light-shielding portion has a first surface parallel to a first direction and a second surface oppositely located to the first surface. The reflective layer covers the first surface or the second surface. The reflective layer can reflect the light irradiated on the surface of the light shielding portion or entering the light shielding portion back to the total reflection display unit again, avoiding the waste caused by the scattered light caused by the propagation path of the light, thereby improving the utilization rate of light.
