step four: transporting the aerosol can through a conveyer belt of the equipment, filling the materials in the third step into the aerosol can while transporting, wherein the filling amount is 0-450 ml, the repeated filling measurement is +/-0.5%, and the filling speed is 800-1200 cans/hour;
step five: and C, filling a certain amount of dimethyl ether as a foaming agent in the container obtained in the step four, then filling a certain amount of propane and butane as a propellant in the aerosol can, sealing the aerosol can, and then repeatedly shaking the aerosol can by using a shaking machine until the materials in the aerosol can be sufficiently and uniformly mixed.
Through mixing and compressing polyether polyol and diisocyanate in this embodiment, make the foamed rubber spray the ejection of compact through the aerosol can, reached and conveniently carried and take up an area of less advantage, still there are many sound absorbing holes through the foamed rubber that sprays the ejection of compact, can realize carrying out syllable-dividing effect in the car, pollution and the influence of external noise in to the car have been reduced, still through adding dimethyl ether and propane butane in manufacturing process, make dimethyl ether and propane butane enter into the inside of aerosol can as foamer and propellant, make the foam state in the aerosol can more stable, the bottle hanging phenomenon can not take place, the waste of raw materials has been reduced, make the use value of foamer big.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
