Viscosity is the ability of anti-position change in liquid. It is one of measurement of inner flow resistance. Measurement of Viscosity plays an important role in petroleum, chemistry, weaving, national defense, machine and electric power. It has great influence of product's performance of fiber-reinforced plastic, such as thickness, intension, gas closeness and cutting intensity etc. The higher resin viscosity is, the poorer its ability of moving and the worse proportioned of resin on the surface of raw and processed materials. On the contrary if resin's viscosity is very low, the capacity of resin in soiled thing become lower. Both this two conditions can lead to decrease product's performance. This article focuses on measurement and control of resin viscosity in Microcomputer control fiber winding machine or dipping glue machine. The purpose of this system is to change resin viscosity real time in accordance to actual needs, and then to improve product's performance.
Now there are some special apparatuses to measure viscosity of liquid, but generally they just have function of measurement and most of them can't communicate with and be controlled by computer. This article brings forward a way of computer control system. It can not only control resin viscosity online and display control curve, but also change target value through friendly control interface. It can be operated easily and it will greatly improve control effect.
