LINE FOR PRODUCING SILICA WOVEN MATERIALS BY LEACHING METHOD Russian patent published in 2022 - IPC D06B21/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to equipment for production of fiberglass predominantly high-temperature-resistant silica fabrics by leaching method. The line for the production of silica woven materials by the leaching method includes a device for unwinding a roll, a pre-wetting bath, successively located acid leaching baths, compensators, a fabric pre-sizing unit, devices for intermediate and final washing of fabric from acid, wringer rolls, a drying chamber and a device for winding the finished product. material. At the same time, non-driven arc and driven screw expanders, rotating in the direction opposite to the movement of the fabric, are installed on the tissue sample from each bath with compensators. In front of the entrance to the first and subsequent baths with compensators, tissue guides and non-driven screw spreaders are installed, which ensure uniform sampling from the baths and wiring along the nodes of the processed tissue line at a speed of more than 100 m/h without sagging, displacement and damage.

EFFECT: invention makes it possible to increase the speed of guiding and productivity of the line, to exclude deformations and damages of the fabric in the process of guiding through the nodes of the line and to expand the range and width of the processed fabric.
