Corrugated cardboard is made of at least one layer of corrugated paper and one layer of carton paper, which has good elasticity and extensibility. Corrugated board consists of face paper, tile paper, core paper and lining paper. It is often used to make cartons, sandwiches of cartons and packaging materials for fragile goods. When we use it, we will encounter the problem of deguming, which is troublesome. So how to solve it?
1. First, we should make paste strictly according to the requirements of mixing ratio and mixing time. Strict control of paste viscosity, generally speaking, the viscosity of single-sided machine paste is 50 seconds to 60 seconds; double-sided glue machine is usually controlled in about 100 seconds, and the paste prepared on the same day.
2. The clearance between the scraper roll and the rubber-coated roll should be adjusted properly. The clearance between the rubber-coated roll and the main corrugated roll is better between 0.10mm and 0.25mm. When adjusting, the gap should be measured with a plug ruler, and the gap between the left and right ends should be the same.
3. The adjustment of clearance should be based on the thickness of corrugated cardboard on each roll. The clearance between press roll and rubber roll is usually smaller than that of corrugated cardboard on one side, 0.05mm-0.10mm is better.
