Rubber Dampers /bumpers/ shock absorbers / vibration reduction

图片
  Rubber Damper   Also called Rubber dampers , shock absorbers and vibration reduction, they  have wide applications . To select suitable rubber damper, firstly we need to know its property, and choose the one fit for the operation environment. The feature of rubber damper is that its shape and hardness can be designed according to specific demand, and it provides larger damping ratio than spring. Meanwhile, rubber damper has advantage of resisting shear, pull and pressure, also easy for assembly. Rubber dampers or  shock absorbers  are used to reduce the transmission of shock to the surrounding structure. Shock absorption is possible as the rubber absorber deflects under the applied shock load. Rubber damper also has its disadvantage such as relatively high inherent frequency, limited application environment. Normally the working  environment should be controlled between -30℃ --- 120℃, some environment with chemical corrosion asks for rubber damper wi...

How does the fire sleeve stop fire and metal splash

  In modern industry, Fire, high temperature and high voltage are the most harm elements to the safety production and human life. How to provide disaster happen,it is always the goal that human beings want to. ZBAO TECH High Temperature Fire sleeve  is made of braided e-grade glass fiber sleeve with silicone rubber coating, which designed as a kind of heavy duty jacket to protect different kinds of hoses, wires and cables from the hazards of high heat and occasional flame. Heavy duty design: 1.Much thicker silicon rubber coating,can resist 7kv--25 kv rated voltage. 2.The thicker silicon rubber coating will transform into a crust when meet metal splash,creating a protective sio2 refractory layer,stop metal splash inside. Continues working at 260℃ Extreme temperature resistance with Max. duration of: 15-20 minutes     +1000°C 15-30 seconds     +1600°C Inside glass fiber can resist 550°C high temperature, and thermal conductivity is just 0.035.T...
