What are the different effects of the use of rubber soft joints and difficult problems in use
Rubber soft fittings reduce vibration and noise and compensate for thermal expansion and contraction caused by temperature changes and are widely used in various piping system software. Good shock absorption. Single spherical rubber soft joint structure is divided into the inner surface layer, inner layer and surface layer, the inner layer is polyester cord cloth frame layer, the original plastic layer of the inner layer is suitable for the first molding of the single 0 round ball rubber soft joint and its bearing basis is not the same substance, the middle is the hard rigid wire layer, the key to bear the high working pressure in the pipeline to avoid bendable rubber soft joints are torn, the surface layer is generally neoprene rubber, suitable for the anti-aging of rubber soft joints and their aging resistance. The plastic materials of the single spherical rubber soft joint are made of raw plastic and crude styrene-butadiene rubber.
Working temperature: -40 degrees to 80 degrees Operation method: first match the connecting head flange plate with the position of the matching flange disc hole, and then pass the fixed screw through the flange disc hole, and use a wrench to clamp the screw cap. So how much noise can be reduced, I think everyone is more vague about this, the pipeline equipment factory professionally did a test, test the rubber soft joint can reduce the noise of how much sound shell, in the vibration machinery and metal material pipeline in the middle of the reasonable installation can reduce the structure transmission noise 15 ~ 25 sound shells, in the housing pipeline many use of rubber soft joints to reduce noise, improve the daily life of the comfortable natural environment. Rubber soft joints should be protected from sun exposure during the application process, and all plastic products are like that.
Rubber joints subjected to severe direct sunlight, rubber soft joints have an index value for the provisions of additives in the production process; Divided into four levels - eight levels, in the case of shading application of four or five sufficient, but if the rubber soft joint in the outdoor sun is very strong application, it is stipulated that the lightfastness level to achieve eight levels, in the injection mold processing raw materials plus ultraviolet absorbers and other tackifiers, that can prevent the rubber soft joints in the bright light application is very easy to fade the problem. The reliability of the dyes used in the manufacture of rubber soft joints determines the level of product fading. The active ingredients of the dye are hydroxides, phosphates, etc., which have good heat resistance and high temperature resistance. The specific raw materials for the production and manufacture of rubber soft joints are: HDPP and HDPE, and the injection molding temperature needs to be above 280 °C, so the heat resistance characteristics of the dye must be taken into account when selecting additives.
