Patent ID: 7264757

Claim:
A controllable microscopic bubble nucleation in fluid polymer material production method and its apparatus consisting of an injection or extraction forming mechanism, utilizing gas as a foaming agent, and the said gas originates from a gaseous state source capable of precipitating foam to provide for the microbubble nucleation of polymer material, the microbubble nucleation methods of which are: a. high pressure gas passes through a gas pipe in a conveyance screw shaft which is indirectly heated utilizing a heater at the outer periphery of a materials pipe; b. the said high pressure gas enters a microbubble generating component at the front extremity of the said conveyance screw shaft, enabling the gas to be evenly outputted as microscopic bubbles from inside irregularly arranged microscopic perforations; c. the said microscopic bubbles and the polymer material are blended and transferred by the said conveyance screw shaft to form a uniform, microbubble permeated polymer material; and, the injected or extracted microbubble permeated polymer material results from simultaneous microscopic bubble generation, blending, and transferring, providing for the rapid and even amalgamation of microscopic bubbles into the polymer material such that when the polymer material is shaped, it is a uniform, microbubble nucleated polymer material.
