Semi-rigid foam? It is mainly used to make automobile dashboard, handrail core, sunshade, gearbox top cover, roof lining, door interior panel, bumper core, thrust pad and so on. Because this kind of polyurethane foam has high pressure load capacity, outstanding shock resistance and impact resistance, it can effectively eliminate vibration noise.
When installing the rubber soft joint, the screw of the bolt should protrude the outside of the joint and tighten the bolts on the end face of each flange repeatedly and uniformly according to the method of diagonal pressure to prevent pressure deviation. Tighten the threaded joint evenly using a standard wrench. Do not use an afterburner to slide, slide or break the movable joint. In addition, it should be checked regularly to avoid loosening and causing the disc to fall off or seep. After the rubber soft joint is under pressure for the first time (such as installation, pressure testing) or before it is put back into use after long-term shutdown, it should be re-pressurized and tightened bolts before it can be put into use. When using or storing rubber flexible joints, high temperature, ozone, oil and acid-base environments should be avoided. Sunny outdoor or windward pipes should be set up sunshade. Sun, rain and wind erosion are strictly prohibited. It is forbidden to brush paint and wrap thermal insulation materials on the surface of rubber soft joints. Due to the aging of rubber products, it should be inspected and replaced in time. Return to Sohu to see more
Guancheng toilet aluminum alloy doors and windows company, rain-proof shutters are used in computer rooms or other public places that need ventilation and rain protection, heat insulation and air flow regulation, and it is composed of rain-proof blades with water collecting ditch, side frame with dripping frame and streamlined adjusting blades, which not only has the advantages of single-layer rain-proof blinds, but also allows staff to adjust the opening of rain-proof shutters according to indoor temperature or ventilation demand. Single-layer rain shutters are divided into vertical and horizontal, mainly used for large shopping malls, exhibition halls, garages and other places of the facade and top sunshade, also has the role of anti-theft insurance. 4. keep the surface of the curtain dry.
McDonnell Douglas 001 is equipped with a suspended McDonnell Douglas 001LED display dashboard and a small solar panel on the front sunshade, which can power the dashboard and body lighting parts or batteries. This greatly improves the durability of the car.
Do a good job in repairing and consolidating the damaged greenhouse of Dendrobium candidum. First of all, repair the damaged greenhouse film and close the greenhouse film to prevent cold air from entering the greenhouse. Generally adopt the form of “greenhouse + middle shed + small shed” or “greenhouse + sunshade + middle shed” to carry on the greenhouse multi-layer covering heat preservation treatment. Then reinforce the Dendrobium candidum greenhouse. Along the longitudinal axis of the large (medium) shed, a support such as bamboo is used to support and strengthen the roof every 2-3 meters, so as to improve the compression resistance of the shed and prevent the shed from falling under snow pressure. If there is external shading equipment on the scaffolding, the shading net on the external shading should be tightened to prevent damage caused by snow pressure. Special snow sweeps should be provided.
First, thermal insulation performance. Good thermal insulation and thermal insulation performance means that the heat preservation time is long, the working time of the refrigerator at the same temperature is short, and the fuel consumption is also followed, which plays the role of energy saving and emission reduction. Second, light weight and strong structure. The body weight of the box consumes more fuel in the process of transportation; on the contrary, if the body of the box is light, it consumes less fuel in the process of transportation. The right outer plate and the right side of the roof are hydraulically lifted to a position perpendicular to the table to form a sunshade, rain shield, lighting-fixed ceiling and advertising load-bearing surface. The right inner plate (stage board) is folded into two folds, which is used as a stage after being flipped by hydraulic pressure. An extension plate is installed on the left and right side of the stage, and a T-shaped platform is installed in front. The hydraulic system is controlled by DCV battery power supply.
