Step 3 is 5KG/cm with above-mentioned glass fabric behind expanding through pressure
2-100KG/cm
2Continuous pressure roller roll processing, and through the body of heater fast shaping of 300 ℃-480 ℃ of excess temperatures;
Step 4 was carried out glass fabric that typing handles and is batched with the destarch wheel and put into debinding furnace above-mentioned, through 250 ℃-450 ℃, 20hrs-64hrs ungrease treatment;
Step 5, with above-mentioned glass fabric through ungrease treatment through excess pressure 5KG/cm
2-50KG/cm
2, the aperture is that 0.1-0.3mm, water temperature are that 10KG/cm is handled, passed through to 25 ℃-85 ℃, the high-pressure spray of vibration frequency 25Hz-50Hz
2-100KG/cm
2Backer roll typing, obtain surface roughness low, open the good glass fabric of fiber number;
Step 6, with above-mentioned glass fabric after the impregnation process of surface conditioning agent silane coupler, the electron gain grade fiberglass cloth.
The present invention brings new treatment process for the fibre of opening of glass cloth, and it is bigger to open fine degree before glass cloth is compared, and cloth cover is more flat, and for the better adaptability of various resins, the impregnation performance obviously promotes, and the flatness of cloth cover is better.
