Impregnation with J fat is divided into two stages: primary and secondary (2-pass method)
For example, in the first impregnation, a water-soluble phenol varnish is used, and in the second impregnation, the whole is impregnated with a thermosetting phenol varnish - in either case, drying after impregnation is carried out by hot air drying. The obtained dry resin-impregnated base material is laminated in a predetermined number and hot-pressed to form a laminate. However, when drying the resin-impregnated base material only by hot air drying in this way, V
In the Cl4,l pass method, the permeability of the resin into the crystal phase during drying is poor, so depending on the drying speed, the resin-impregnated base material may become sticky, and the punching workability and electrical properties of the laminate may be poor. In the two-pass method, the resin-impregnated base material breaks during drying, and a large amount of solvent is required to adjust the resin content during the primary impregnation.

In these figures, l is the base material, 2 is the resin liquid for primary impregnation, 3 is the tank, 4 is the coating roll, r is the base material after the primary impregnation, 5 is the radiant heat drying zone, and 6 is the secondary impregnation. A resin liquid for impregnation, 7 is a tank, 8 is a guide roll, 1 is a base material after secondary impregnation, and 9 is a hot air drying zone. The tunnel-shaped radiant heat drying zone 5 has oil pipes 51 and 52 through which hot oil flows, disposed near the ceiling and bottom of the zone, and a resin-impregnated base material R passing between the oil pipes 51 and 52 above and below. It moves in the direction of the arrow. The hot air drying zone 9 has the same structure as a known one. Okay, to explain in detail, the total length of both zones 5 and 9 is 1.
