The difference between the static conductive hose and the anti-static hose, according to the specific working conditions, choose the corresponding static discharge hose
   Anti-static hoses generally require surface resistance to be at least less than 10 to the 9th power ohm, and conductive hoses to have a surface resistance of less than 10 to the 4th power ohm. Generally speaking, if it is a slight dust, conveying powder, due to the influence of the magnetic field in the environment, static electricity will be generated when the medium is in contact with friction. When the pipeline is used, the things flowing through the pipeline will generate friction, which will be static for a long time. Otherwise, it will cause a certain amount of wear and tear on the pipeline, which is not conducive to the long-term use of the pipeline. At this time, you have to use an anti-static hose.
   But if you transport some metal powder or some flammable and explosive media, then also in order to ensure the service life of the hose and from the perspective of safety, you must use a conductive hose.

   1. What kind of dust is explosive
  1, agricultural products. Cereals, flour, starch, milk powder, sugar, feed products
  2, agricultural and forestry products. Tobacco, wood dust, cotton fiber, flax fiber
  3, metal dust. Magnesium powder, aluminum powder, zinc powder
  4, mineral products. Coal powder, sulfur powder, phosphorus powder, coke dust, asphalt dust
   5. Petrochemical products. Plastics, resins, petroleum rubber powder, antioxidants
  6. Chemical dust. Pharmaceutical powders, pesticides.
   2. What kind of environment is needed for a dust explosion?
  1, a certain concentration
  2, sealed space
  3, detonate sparks
   Three, safety precautions
  1. Eliminate possible sources of fire and power
  2, up to standard dust removal measures to eliminate flammable and explosive environment
   Fourth, the choice of vacuum hose
  1, ordinary vacuum hose (Hangzhou Haikuo ordinary industrial hose also has anti-static function, anti-static through wire grounding)
  2, anti-static hose (special anti-static factor added to the hose, surface resistance <10 to the 9th power)
  3, conductive hose (surface resistance <10 to the 4th power)
   The specific choice of anti-static hose or conductive hose is determined according to specific working conditions. If you need any consultation, please feel free to contact Hangzhou Haikuo sales engineer!
