Description
Technical field
The present invention relates to a kind of mechanical cleaning technical field, the cleaning of specifically a kind of polyurethane foaming machine material feeding rifle is set
It is standby.
Background technique
High-presure polyurethane foaming machine is mainly for the production of semi-hard polyurethane product, and such as foamed heat insulating pipeline, foam poly- ammonia
Ester plate, foamed heat insulating plate etc..Polyurethane foams is then sufficiently mixed in the mixing head on high-presure polyurethane foaming machine.Isocyanide
Acid esters and polyalcohol be all in mixing head mix after, casting chamber in, shut down when should be as early as possible by the residual in mixing chamber
Object washes, and otherwise, these residues will constantly cure generating polyurethane, it is very strong to mixing chamber adhesive force, if not in time
It washes, will affect foaming machine everything goes well with your work and carry out.In foaming machine foaming work, residue is cleaned as early as possible and thoroughly
