3. Technical structure of air conditioning hose:
?
? ? For regular A/C hose has four layers, we call this A/C hose as type E air conditioner hose. Inside tube ? ? ? is nylon (PA), middle layer is EPDM or IIR (Isobutylene-Isoprene Rubber), the reinforced layer is PET or ? ? single high strengthen weaving fiber braided. Outer tube is EPDM with black and smooth cover.
? ? Here is another type of A/C hose with five layers. The inside tube is EPDM not PA. We call type C air ? ? ? ? conditioner hose.
?
?
4. Production technology of air conditioning hose:
?
? ? When making A/C hose,?mandrel process is used here. That means there will be a mandel when ? ? ? ? ? ? ? making inner tube in order to make the inner diameter sizes more precise. For the cover, it is mill finish ? ? ? and shining, a layer of PVC is added when making the cover, then??we will do some vulcanization for the ? ? cover and?remove the PVC layer finally. And there are some very small holes on the cover?for gas ? ? ? ? ? ? evacuation not to let the outer tube burst. All the production skill will guarantee our A/C hose to have ? ? ? ? good performance.
?
?
5. Application of air conditioning hose:
?
? ?A/C hose is mainly used to convey the medium of refrigerant such as R134a, R12, R22 etc. Applied ? ? ? ? ?widely to auto refrigeration in automoblie air conditioning system like?bus transit system.?
