Carton packing factory will meet a headache problem in the production process, is the collapse of a box and carton carton box machine stick glue rickety, day into the summary given solution is to improve the mechanical board material, improve the carton compressive strength and moisture resistance, thereby reducing the rate of collapse. In addition, the carton factory needs to increase the adhesive strength of the carton, increase the solid content of the starch paste, and increase the hardness of the paperboard by reducing the amount of glue on it.
Carton packing factory how to deal with sticky machine sticky, carton collapse box production, use should pay attention to the following points:
1, to control the use of base paper
Check the sizing of corrugated paper, the surface water absorption index, efficacy. If the base surface sizing is bad, water absorption will be on the high side, it is easy to hand cold storage, low temperature, wet environment impact, leading to carton resurgence, softening, finishing compression strength lower.
2, the production of cardboard to control the moisture content of cardboard
The moisture content of the cardboard should not be excessive, because the moisture content is large, the hardness of the cardboard is low, affecting the edge pressure index of the paperboard. In the process of paperboard processing, the single machine and double-sided machine process can not be too large amount of glue. Once the amount of glue is large, the shape of the paperboard will be deformed, and the shape of corrugated is directly affected by the edge pressure of the paperboard, while the edge pressure is reduced, and the compressive strength of the carton is also reduced.
3, the adhesive strength of cardboard is big
Adhesion strength is the adhesive force between corrugated paper and inner paper and facial paper. If there is a false stick in the carton, the carton is pressed, the paper or the paper will be separated from the corrugated paper, then the carton's compressive strength will plummet.
4, the production process of gap pressure control to moderate
Pay particular attention to the gap pressure cannot paste box machine paste is too small, double-sided machine, a sun wheel gap pressure die-cutting machine should be controlled in a reasonable range, to avoid the corrugated crushing effect of compressive strength of cardboard cartons.
5, the use of water repellent, waterproof varnish, etc., to solve the waterproof and moisture-proof carton surface.
