| 摘要 | The invention provides a method and apparatus for optimally feeding an ASA emulsion into a papermaking process. An intense transmission of ultrasonic energy rapidly and efficiently forms an ASA emulsion. Nearly simultaneous to forming the emulsion, the emulsion is fed into a high-speed dual conduit feeding apparatus (12), which quickly mixes the ASA emulsion with other chemicals and feeds the mixture directly into a papermaking process. The invention operates so fast that virtually no hydrolysis of the ASA occurs. This both prevents damage to the papermaking machinery and improves the quality of the produced paper. The invention operates 10-20 times faster than mechanical based emulsion methods and requires 1/7 as much energy to operate. The invention also self-monitors the process and can automatically correct any detected problems with the fed ASA emulsion. | ||||||
