The specific embodiment
Below in conjunction with concrete embodiment the present invention is described in further detail.
The production method of high filler cultural paper provided by the invention can may further comprise the steps:
Step 1, the wood pulp size degradation of certain part by weight disperseed to mix with the calcium silicate filling material of certain part by weight obtain paper pulp; Described paper pulp thin up is obtained mixed slurry A;
Be specifically as follows: send into after the wood pulp of certain part by weight is disperseed with the hydrabrusher size degradation and kowtow preceding pulp storage tank, the calcium silicate filling material that adds certain part by weight this is kowtowed before in the pulp storage tank obtains paper pulp, adds the water adjusting in this paper pulp then and obtains mixed slurry A; Wherein, wood pulp can be bleached wood pulp.
Step 2, with after the mixed slurry A that obtains in the step 1 making beating, thin up obtains mixed slurry B;
Be specifically as follows: with disc mill the mixed slurry A that obtains in the step 1 is pulled an oar after certain beating degree, thin up obtains mixed slurry B, mixed slurry B is sent into kowtow the back pulp storage tank then.
Step 3, the mixed slurry B that obtains in the step 2 purified slagging-off after, add reinforcing agent, dispersant and retention and drainage aid agent, obtain mixed slurry C;
Be specifically as follows: the mixed slurry B that obtains in the step 2 is sent into the pond of sizing mixing after pulp screen and desander purification; In the pond of sizing mixing, add a certain amount of reinforcing agent then, stir and mix; In the pond of sizing mixing, add certain amount of dispersant again, stir and mix; Add a certain amount of retention and drainage aid agent as required again, obtain mixed slurry C.Wherein, the addition sequence of reinforcing agent, dispersant and retention and drainage aid agent can be decided according to the actual requirements, and the present invention does not limit.
Thin up obtains mixed slurry D among step 4, the mixed slurry C that obtains in the step 3, mixed slurry D can be sent into then and copy preceding stock tank.
Step 5, with paper machine with the mixed slurry D that obtains in the step 4 cultural paper of manufacturing paper with pulp out;
Concrete, can use the paper machine required quantitative cultural paper of manufacturing paper with pulp out as required, for example: can be by the speed of a motor vehicle of control head box flow velocity and the paper machine required quantitative cultural paper of manufacturing paper with pulp out; Behind the cultural paper of manufacturing paper with pulp out, can add a certain amount of latex coating again and carry out dip coated.
Wherein, reinforcing agent is water miscible PVA (polyvinyl alcohol) fiber, and reinforcing agent can directly add in the mixed slurry and mixes with paper pulp fiber, copies when dry behind the paper to be combined the generation humidification with paper pulp fiber.
Dispersant is polyethylene glycol oxide (PEO), and to become mass fraction be 0.5～6% solution to thin up during use, adds in the mixed slurry fiber is evenly disperseed, and guarantees the evenness of paper.
Retention and drainage aid agent is for example PAM (polyacrylamide) of high molecular polymer, and the purpose that adds retention and drainage aid agent is the drainage rate when accelerating the shaping of l Water Paper page or leaf.
The mixing material that latex coating is made up of starch, active silicic acid calcium micro mist, AKD (alkyl ketene dimer), latex etc. is attached to paper surface uniformly, forms level and smooth bright and clean surface; Perhaps, also available carboxylic styrene butadiene latex of latex coating; To be coated with latex is coated on can increase paper in the page surface strength with infusion process, and prevent the paper layering and give paper anti-water humidity resistance.
