Cloth cover foam eliminating device of electronic grade glass fiber cloth

Abstract

The invention provides a cloth cover foam eliminating device of an electronic grade glass fiber cloth. The device comprises symmetrically-arranged extrusion wheels comprising immersion troughs, dryingovens, ventilation pipes, a fan, a hot blast heater and a ventilating board. The drying ovens are symmetrically arranged and located above the extrusion wheels comprising the immersion troughs, the ventilation pipes are symmetrically arranged at the outer sides of the drying ovens, and the fan, the hot blast heater and the ventilating board are sequentially arranged at the upper sides of the ventilating pipes; the electronic grade glass fiber cloth penetrates through a gap between the extrusion wheels comprising the immersion troughs, hot-blast air inside the ventilating board preheats and dries the penetrated electronic grade glass fiber cloth, and therefore cloth cover foams on the surface are eliminated; the requirement for temperature and pressure of hot-blast air on the ventilating board is met, foams on the cloth cover are eliminated through hot-blast air, the uniform dispersion effect on a silane coupling agent hydrolysate is achieved, and therefore abnormity such as remainingwater stains, spots and cloth stains obtained after foams are eliminated is avoided, the cloth cover improving rate reaches 90% or above, and therefore the appearance quality of the cloth cover of theelectronic grade glass fiber cloth is improved.

Description

technical field [0001] The invention belongs to the post-processing technical field of glass fiber cloth, and in particular relates to a cloth surface foam elimination device for electronic grade glass fiber cloth. Background technique [0002] Due to the chemical characteristics of the treatment liquid in the post-treatment section of the electronic grade glass fiber cloth, in the production process of the glass fiber cloth, after the electronic grade glass fiber cloth is impregnated, a large amount of foam will be generated under the repeated extrusion of the extrusion wheel and adhere to the extrusion wheel. On the surface of the electronic grade glass fiber cloth, the thicker the glass fiber cloth is, the faster the production speed of the glass fiber cloth is, and the more foam is produced on the surface of the electronic grade glass fiber cloth. [0003] At present, the post-treatment of electronic grade glass fiber cloth is treated with silane coupling agent hydrolyza...

AI Technical Summary

Problems solved by technology

And the increase of foam will bring many problems. Firstly, the increase of foam reduces the recycling efficiency of silane coupling agent hydrolyzate, increases the cost, and the foam will accelerate the polymerization of silane coupling agent hydrolyzate, affecting its use effect; the most important The most important thing is that the large amount of foam attached to the cloth surface will make the electronic grade glass fiber cloth difficult to dry, and the cloth surface will easily leave abnormalities such as water stains, spots and cloth stains, which will seriously affect the appearance quality of the cloth surface, and easily cause poor use and complaints from customers. And other issues
