A pneumatic polyurethane spraying machine belongs to the airless and high-pressure mixing type. It is mixed under the high-pressure impact, uniform mixing, fine atomization and flat surface after foaming.
Specific principle of pneumatic polyurethane spraying machine:
1. Two feed pumps are inserted into the industrial vats containing component A and B respectively, and the materials enter the host from the feed pump along with the supply pipe
2. The volume ratio is controlled by the precision metering pump in the host machine to be 1: 1, and at the same time it is heated and pressurized by the host machine.
3. The material flows out of the host, passes the insulation hose, and reaches the spray gun
4. After the trigger is pulled, high pressure impacts the mixing in the mixing chamber from the respective direction through the filter screen, and it sprays out at high speed and receives compressed air at the nozzle to form a uniform sector or circular material surface
5. Sprayed on the steel tube to solidify
