Honeycomb Glue Film and Dry Speed: Slow, Fast, Quick, or Instant

Dry speed on /products/honeycomb-line-glue is a choice, not a single setting for every honeycomb plant. The line grades are made as slow-dry, fast-dry, quick-dry, and instant-dry. The glue film can be elastic or rigid. Core-strip glue and facing glue are still separate grades. Picking “instant” does not merge them.

Choose dry speed from the stack, not from a wish to run faster. The board has to be dry enough to stack or cut on the time that section actually has. Instant dry on a coater that cannot lay an even film moves the defect from a wet board to a starved bond. Slow dry on a line that stacks immediately leaves the face wet into the pile. Name the stack time when you order.

Elastic film or rigid film is the other half of the same order line. Say which face the board needs: a film that stays able to move with the paper, or a film that sets hard. Do not leave it as “standard.” The two are both supplied. The trial should run the one that was named.

Water and dry speed, facing route A only

On the complete low-temperature facing powder, the plant adjusts inside 30–40 kg of room-temperature water per 25 kg of powder. Less water dries faster and raises viscosity. More water dries slower. The coat still has to lay evenly. A quantified formula below 30 kg of water has not been confirmed. Do not chase a faster dry by stepping under that floor.

That water band is not a dry-speed control for the other products. Route B, where the plant adds starch and filler, uses 40–60 kg of water and a two-tank mix. Core-strip glue does not use either band. Paper-tube glue and corrugator glue do not use them. Neutral adhesive on /products/neutral-adhesive has its own specification, including a 2–4 second set at operating temperature. That set time is not a license to cut water on the facing powder.

Heat sits beside dry speed. It does not replace it. A slow start can run with the heater off. Heat raises line speed when the plant needs it. Core making stays in about 10–200 m/min. Face laminating stays in about 4–30 m/min. Changing dry speed does not move a section from one window into the other.

What to write on the order

Core grade or facing grade, as two lines.

Dry speed: slow, fast, quick, or instant, and the stack time it has to meet.

Elastic film or rigid film.

Facing route, if this line is the facing grade: water only, or starch and filler added.

Heater on or off for the trial, and cold press or hot press.

The mixing steps for the two facing routes are in “Honeycomb Facing Glue: Floor Mixing for the Two Routes.” This page only decides how fast the film should dry and which film was asked for.
