Modern papermaking procedures can be divided into pulping, modulation, ChaoZao, processing and other major steps.

1, slurry-making process: the first step for paper pulp, in lumber into a pulp methods include mechanical pulp method, chemical method and half pulping chemical pulp method 3 kinds.

2, modulation process: paper feeding of modulation of another emphasis for paper, paper after completing the intensity, tonal, printing, paper preservation sex the superiority of the maturity of a direct about it.

General common modulation process can be roughly divided into three steps: scattered pulp, beating, adding glue and filling.

3And ChaoZao process: the department's main job is to will dilute paper feeding, make its uniform interweave and dehydration, then after drying, pressure light, paper roll, cutting, sorting, packaging, so general common process is as follows:

Paper material selection: modulation paper feeding again into the lower concentration dilution and through the screening equipment, again screening sundry and not disintegrate fiber bundles, in order to maintain quality and protection of equipment.

Nets department: the paper material from the copper wire in circulation box outflow net, or plastic online and evenly distributed and textures.

Squeezing department: will net surface move wet paper leads to a rolling roll with two headwear by rolling roll between the squeezing and headwear salt-resistant of role, will wet paper further dehydration, and to make paper relatively close to improve paper, increase the intensity.

Press polishing: because pass de-stemmed wet paper, its moisture content is still up52-70And now can't reuse mechanical force to remove water pressure, so to make wet paper after many a general hot steam cylinder within the paper dry surface.

Paper: because pass de-stemmed wet paper, its moisture content is still up52-70And now can't reuse mechanical force to remove water pressure, so to make wet paper after many a general hot steam cylinder within the paper dry surface.

Cutting, sorting, packing: take front has rolled into tubular paper roll multivessel, with sheet slitter slit cropped to a covering of paper, then after artificially or mechanical and sorting, remove damaged or stains of paper, will ultimately every 500 packets into a pack of (usually called a enabled).
