Ultrasonic atomizing device and atomizing method for liquid-containing binder for glass cotton

Abstract

The invention relates to an ultrasonic atomizing device and an atomizing method thereof, in particular to an ultrasonic atomizing device and an atomizing method for a liquid-containing binder for glass cotton. According to the device, the coordinated function of air pressure atomizing and ultrasonic vibration atomizing is used, and a flow adjusting needle valve or an anti-blocking removing valve is selected to adjust the flow of the binder and prevent the binder from blocking. When the binder with a certain viscosity is sprayed out, a good atomizing effect is realized as the particle size of the liquid-containing binder is small, the usage rate of the binder is effectively improved, the production cost is reduced, meanwhile, the liquid-containing binder is more uniformly dispersed in glass fibers, the color difference of the glass cotton product is reduced and the tear strength of the glass cotton product is effectively improved.

Description

technical field

[0001] The invention relates to an ultrasonic atomization device and an atomization method thereof, in particular to an ultrasonic atomization device for liquid binder for glass wool and an atomization method thereof. Background technique

[0002] Glass wool is a glass fiber product made by fibrillating molten glass and adding an environmentally friendly formula binder based on thermosetting resin. The fibers inside the glass wool are fluffy and interlaced, and there are a large number of tiny pores. It has the characteristics of low thermal conductivity, good sound absorption performance, good electrical insulation performance, high elastic coefficient, low water absorption, chemical corrosion resistance and Class A non-combustibility, etc., and is widely used. In the fields of electromechanical, metallurgy, petroleum, chemical industry, construction and aerospace.

[0003] At present, the combination of glass fiber and resin binder is mainly based on mecha...
