Abstract
The invention discloses a paper web gluing process based on membrane transfer, which mainly comprises the following processing steps of: pretreating raw paper, preparing a glue solution, accurately metering by using a metering roll, coating a glue film or paint thin film on the surface of a loading roll, transferring the glue film on the paper web at a roll pressing region, and drying. As the process disclosed by the invention adopts an advanced membrane transfer gluing method to glue a white board, which is improved on the basis of the traditional two-roll gluing and squeezing, the spinning and glue leakage are avoided, interrupted paper feed, crumples and other problems can be solved, the streamer of glue consumption is consistent, the gluing quality is greatly improved, the operation method is simple, safe and reliable, the production efficiency is high and the cost is low, and the process is applicable to the gluing process link which has high quality requirement on paper printing performance at a high speed.
Description
Technical field
The present invention relates to pulp technology for making paper, be specifically related to a kind of paper web coating technique that shifts based on film.
Background technology
The paper surface coating technique is the pith of sheet processing arrangement, directly influences the quality of paper printing characteristic, as: falling hair, dry linting, distortion, banner glue-spread inequality, soft durometer etc. all is the quality problems that very easily cause in photoresist coating process.
Traditional glue spreading method mainly is to adopt two roller size press, and namely the roller of common two diagonals layout forces together, and glue forms a Jiao Chi above nip, when paper passes through nip, adsorb certain sizing material, finishes the applying glue process.But this mode only limits the use of in low speed, can not satisfy under the high speed of a motor vehicle trend of paper machine in recent years the demand to the high-quality sized paper.Because paper machine speed is more high, whirl coating, to leak the glue phenomenon just more serious, splashes for reducing the roller glue that forms that runs up, and the roller footpath of application roll must be strengthened, and the increasing in roller footpath causes transmission to consume also to be increased accordingly.Secondly, because that roller runs up is excessive to the disturbance of glue, cause resin added skewness in the horizontal, for increasing the flowability of glue, guarantee the even of resin added, along with the raising of the speed of a motor vehicle, the concentration of glue reduces, and then has increased the steam cost of back oven dry portion.In addition, be easy to generate disconnected paper and fold phenomenon before and after the two roller size press.Therefore, size press more and more can not satisfy client's demand.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of paper web coating technique that shifts based on film is provided.
The step of the paper web coating technique that shifts based on film is as follows:
1) carry out the press polish preliminary treatment for body paper before the gluing, rolling condition is: 23 ℃, and 600KPa, speed is 20m/min;
2) under normal pressure, configuration sizing material concentration is 20%～40% glue, and the temperature control of glue is in 35～55 ℃ of scopes;
3) under 35～55 ℃ of working conditions of temperature, the glue conveyance conduit is delivered to glue in the groove between metering roll and the last material roller, accurate measurement spread after rough segmentation and segmentation;
4) under 35～55 ℃ of temperature, pressure 20KN/m process conditions, the glue after the metering forms one deck glued membrane or paint film on last material roller surface, and the glue solid content is 8%～20%;
5) be under the condition of 30KN/m in 35～55 ℃ of temperature, roller nip pressure, material roller in the rotation, the glued membrane that has generated on the roll surface are transferred on the paper web that is in two material loading roll nip, and resin added is 0.5～2g/m
2
6) the paper injection system will be the cardboard of gluing deliver to next link and carry out high efficiency drying and handle.
Described a kind of paper web coating technique that shifts based on film, it is characterized in that: the accurate measurement described in the step 3) realizes by the groove metering device, this groove metering device comprises described metering roll 1, steel wire rope 2, described upward material roller 3, pressure-regulating device 4, connects adhesive dispenser 5, the two ends of described metering roll 1 and described two ends of going up material roller 3 are separately fixed on the pressure-regulating device 4, steel wire rope 2 described metering roll 1 and described between the material roller 3, connect the downside that adhesive dispenser 5 is installed in described metering roll 1.
Described a kind of paper web coating technique that shifts based on film is characterized in that: control glue-spread by changing wirerope diameter and pressure adjusting channel slot space.
Technology of the present invention is compared with traditional handicraft, and its advantage is:
1) because the present invention adopts is that film shifts the coating technique method, can guarantee good runnability, good precision and the processing safety of applying obtains the higher paper product of surface strength and flatness;
2) adopt film generation technique improvement roll surface, make roll surface can generate glued membrane, with the mode gluing that film shifts, whirl coating, the leakage glue phenomenon of just having avoided traditional size press to be easy to generate can satisfy speed of a motor vehicle stable operation in 200～2000m/min scope;
3) adopt unique groove metering method, twined import stainless steel steel wire at last metering roll and following metering roll roll surface, control what of resin added by changing steel wire diameter and pressure, and because steel wire forms the uniformity in space, make horizontal resin added reach consistent;
4) can be to paper two sides while gluing, coating weight can be independently adjustable, can reduce two sides difference and the morphotropism of paper, increases counter-bending ability;
5) film shifts and can realize the high solids content applying glue, gelatin concentration can reach 16%～20%, doubles than common size press, and moisture reduces in the colloid, same resin added makes the steam consumption of back oven dry portion reduce 15%-20%, has directly reduced the energy consumption of paper product oven dry.
The film that the present invention uses shifts coating technique, and in traditional size press, energy-saving consumption-reducing reduces cost, and is simple to operation, and the gluing effect is better, improves quality and the production efficiency of product.
