The production materials are basically the same: the pulp molding production and the paper and cardboard production can use the basic papermaking materials, such as reed, bagasse, wheat straw and other herbaceous plant fiber slurry or discard the paper product to recover the slurry. The chemical additives used in the production process are also basically the same, such as retention aids, filter aids, wet strength agents, dry strength agents, water repellents, oil repellents, dyes, brighteners, etc. There are also environmentally friendly materials. Made of environmentally friendly paper support.
The material processing technology and equipment are basically the same:
If the waste paper material is used to produce cardboard, it must be sorted by waste paper, broken up by a hydraulic pulper, pulped by a beating machine or a refiner, and pulp sizing. The pulping and other processes are then pumped to the paper machine for sheet forming, squeezing and dewatering, and drying cylinder drying processes to become paper products. Pulp molding production uses wheat straw pulp or waste paper materials, which must also be broken down by a hydraulic pulper, pulper or refiner, pulp sizing, pulping and other processes, and then transported to the paper plastic molding machine for molding, Processes such as kneading dehydration, drying and shaping, etc., become qualified pulp molded products. The material processing equipment in the two production processes can even be used universally, but they are different in terms of molding and drying equipment.
The forming principle is similar:
Although the forming principle of paper tray and cardboard is similar, the way of products is different. The production of paper trays and the production of paper and cardboard are all formed by wet forming, and then dehydrated and dried into products. The difference is that the paper or cardboard is "sprayed" or "fished" on the forming net (metal net or plastic net) in the wet part of the papermaking machine to dehydrate and form. The wet paper and dry products are all continuous flat ribbons. , And rolled into a roll-like way.
Differences: The forming and drying equipment used by the paper tray and the cardboard are different. The paper or cardboard papermaking machine is generally a relatively large, forming and boring equipment.
