The main causes of accidents caused by accidental curing of two-component coatings in barrels or equipment include:
Reason A: The viscosity of materials A and B is inconsistent
Solution: Add thinner on the slow side to adjust slowly, add 100-200 grams each time to try slowly, the balance is good, and the maximum of 1 group of ingredients does not exceed 1 kg
Reason B: The moisture of the paste curing agent is too high, which affects the viscosity of B paint and cannot be atomized
Solution: Consult the coating manufacturer and replace the curing agent
Reason C: The wear of pump maintenance kits A and B is inconsistent and the work is not synchronized
Solution: The maintenance kit should be replaced at the same time as much as possible to avoid inconsistent wear on both sides and cause off-market materials
Reason D: The repair kit does not match the ceramic pump rod, there is pulsation, retraction
Solution: Replace the repair kit and tighten it as much as possible to avoid pump pressure leakage
Reason E: The pressure of pumps A and B is out of sync
Solution: It is recommended to install a hydraulic distributor to distribute the pressure of the two pumps 1:1
Reason F: Inconsistent nozzle flow
Solution: Change the nozzle with a larger flow rate on the slow side
Reason G: The pipeline is not cleaned, the pipe wall is thick, the inner diameter is small, and the material is slow
Solution: Replace the pipe, clean the equipment thoroughly at the end of each construction (the internal mixing gun must be cleaned for 2 minutes in the middle of the work)
Reason H: Gun curing
Solution: Replace the needle repair kit
Cause I: Clogged filter
Solution: Check the suction tube and filter screen, replace the filter with a new one
