7results about How to "Reduce water accumulation" patented technology

The application discloses a hydrophobized mouth mirror and a preparation method thereof. The mouth mirror comprises a mouth mirror base and a polysiloxane coating modified on the mouth mirror base. The application modifies the siloxane with a terminal group reaction group on the mouth mirror by a wiping method, rapidly hydrophobically modifies the mouth mirror surface, can make the mouth mirror surface have obvious dynamic repellency to blood drops, so that bloodstains can quickly and non-residually slide off the mouth mirror surface. Meanwhile, due to the lubricating effect of the liquid-like, water can easily slide on the hydrophobically modified mouth mirror surface with an inclined angle without any adhesion phenomenon; and compared with the unmodified mouth mirror, the application can realize the rapid removal of water drops by grafting the siloxane with a terminal group reaction group on the mouth mirror surface, so as to reduce the water accumulation on the mouth mirror surface.

The utility model discloses an air drying device for wire harness processing, which belongs to the technical field of wire harness processing and comprises a workbench, a first support frame fixedly mounted on the workbench and a guide wheel rotatably mounted in the first support frame. Through cooperative use of all the devices and arrangement of the wiping mechanism, a movable disc can drive a hinge base to move synchronously, a connecting rod in the hinge base further pushes a rotating rod to rotate, the rotating rod guides a wiping plate to move correspondingly, it is ensured that the wiping plate is tightly attached to the side surface of a wire harness, and after a guide wheel is started, the wire harness is moved; meanwhile, the wiping plate can effectively remove moisture on the side surface of the wire harness, the water accumulation phenomenon at the bottom of the wire harness is reduced, impurities and moisture on the surface of the wire harness are removed, and the wire harness processing quality and efficiency are improved.

This utility model relates to a special anti-slip polymer self-adhesive roll material for roof expansion joints, belonging to the field of roof construction technology. It includes a prefabricated roof panel, with a polymer roll material laid on top of the prefabricated roof panel, and an anti-aging board laid on top of the polymer roll material. The polymer roll material is fully bonded to the side of the prefabricated roof panel in contact with it. The beneficial effects of this utility model are that by setting the prefabricated roof panel with a structure that is higher in the middle and lower on both sides, rainwater on the surface of the anti-aging board can be quickly drained, thereby reducing water accumulation on the roof after the anti-aging board is laid around the perimeter. Furthermore, in humid environments, the active substances in the adhesive coating penetrate into the concrete casting and react chemically with calcium ions in the concrete casting to generate water-insoluble calcium silicate crystals. These crystals fill the capillary channels, making the concrete casting denser, thus achieving a better waterproof effect.

The utility model is applicable to the technical field of vegetable preservation, and provides a cold storage processing device convenient for vegetable preservation, which comprises a cold storage box, the partition plate is fixedly mounted in the refrigerating box and divides the refrigerating box into a refrigerating cavity and a mounting cavity; the refrigeration pipe is fixedly installed in the partition plate, and the refrigeration pipe and the refrigeration cavity are correspondingly arranged; the carbon dioxide bottle is arranged in the mounting cavity; the exhaust pipe is fixedly mounted at the top of the carbon dioxide bottle; the electromagnetic valve is arranged on the exhaust pipe; and the exhaust mechanism is arranged in the mounting cavity and used for guiding carbon dioxide into the refrigeration cavity. According to the cold storage processing device convenient for vegetable preservation provided by the scheme, a gas preservation technology is introduced, so that the concentration of carbon dioxide and oxygen is changed, the respiration rate of vegetables is reduced, the aging process is delayed, and the preservation time of the vegetables is remarkably prolonged.
