Description

Фильтры из стеклоткани, получаемые пропиткой ее композицией на основе эпоксидной смолы с последующим отверждением, не обладают требуемой пористостью (скважностью ). Дл  достижени  этой цели предлагаетс  пропитанную композицией стеклоткань продувать гор чим сжатым воздухом.Fiberglass filters obtained by impregnating it with an epoxy resin composition followed by curing do not have the required porosity (porosity). To achieve this goal, it is suggested that the glass fiber soaked with the composition be blown with hot compressed air.

Пример. Берут стеклоткань, пропитывают ее композицией на основе эпоксидной смолы ПН-1, укладывают на перфорированнуюExample. Take fiberglass, impregnate it with a composition based on epoxy resin PN-1, placed on a perforated

оправку и продувают гор чим сжатым возду хом до отверждени  композиции.the mandrel and blown with hot compressed air until the composition is cured.

Предмет изобретени Subject invention

Способ получени  фильтра из стеклоткани путем пропитки ее композицией па основе эпоксидной смолы, отличающийс  тем, что, с целью получени  требуемой пористости (скважности) фильтра, пропитанную стеклоткань продувают гор чим сжатым воздухом до отверждени  композиции.A method of obtaining a fiberglass filter by impregnating it with an epoxy resin based composition, characterized in that, in order to obtain the required porosity (porosity) of the filter, the impregnated fiberglass is blown with hot compressed air before the composition is cured.
