What are the properties of the rubber diaphragm

Rubber diaphragm properties: also known as rubber film sealing products, rubber diaphragm. It is a sheet rubber product. It is composed of single layer or multi-layer fabric coated with glue on both sides, or pure glue without fabric. According to the structure, it can be divided into planar diaphragm, corrugated diaphragm, disc diaphragm and rolling diaphragm. According to the principle of action, it can be divided into diaphragm, permeable diaphragm and moving diaphragm. According to the use conditions, different fabrics and adhesives can be selected. Commonly used are nitrile rubber, polyurethane rubber, nitrile / polysulfide compound, but also silicone rubber, fluororubber and chlorohydrin rubber. The diaphragm should have the advantages of heat resistance, medium resistance, pressure resistance, flexure resistance and high sensitivity. The manufacturing method is to vulcanized the fabric and the rubber, and then use the model to make the mold vulcanized. The flat diaphragm can also be washed after continuous vulcanization by the drum vulcanizing machine. Rubber diaphragm is widely used in industry, transportation and other departments to transfer pressure or isolate two kinds of liquid. It can be used as sensitive element of instrument, regulator and other automatic control system. The working temperature is generally - 50 ~ 100 ℃, and the working pressure is 0 ~ 0.2MPa.
