Abstract
The invention provides a process for applying a neutral sizing agent to surface coating, which is implemented by changing addition step and addition amount of the neutral sizing agent. The process comprises the following steps of: pumping the neutral sizing agent into a surface adhesive storage tank by use of a metering pump, mixing with an adhesive, and coating onto the surface of a paper product in a surface sizing machine under such conditions that the concentration percentage of the surface adhesive is 8% to 10%, the amount of the neutral sizing agent is 8 to 10 kg per ton of paper, the temperature is 55 DEG C to 65 DEG C, and the pressure is 0.3 MPa to 0.4 MPa. The invention has the advantages that: the retention rate of the neutral sizing agent is greatly increased, the curing speed is accelerated, the growth of bacteria and other microorganisms in the slurry is inhibited and the surface absorption of the paper product is greatly reduced. The consumption of the neutral sizing agent is reduced from 10 to 15 kg per ton of paper to 8 to 10 kg per ton of paper, and the sizing cost per ton of paper is reduced.
Description
Affiliated technical field
The present invention relates to a kind of paper-making pulping process, especially a kind of neutral sizing agent dose technology.
Background technology
Neutral sizing is to adapt to the glue-applying technique that neutral papermaking grows up, and neutral sizing has equipment corrosion little, and page is difficult for aging, reduces production costs, and pollutes advantages such as few, and the main now rubber polymer that uses of neutral sizing agent is like AKD, ASA etc.
General neutral sizing agent often is added in the slurry, and retention is low, and slaking is slow, and is easy to breed bacteria and microorganism, can not reach the purpose of hard-sized.
Summary of the invention
The objective of the invention is to avoid the deficiency of prior art and provide a kind of neutral sizing agent to be used for the technology that add on the surface.
Technical scheme involved in the present invention is: neutral sizing agent is used for the technology that add on the surface; Interpolation step and addition to change neutral sizing agent are realized, pump into neutral sizing agent in the surface glue holding vessel with measuring pump, mix the back is applied to into paper at the surface size press place surface with glue; The surface glue percentage is 8-10%; Neutral sizing agent is a 8-10kg/ ton paper, adds 55-65 ℃ of temperature, pressure 0.3-0.4MPa.
Compared with prior art, advantage of the present invention is: improve the retention of neutral sizing agent greatly, accelerated slaking speed, reduced owing to be added on growing of interior bacterium of slurry and microorganism, be lowered into the surface absorption of paper significantly; The neutral sizing consumption is reduced to a ton paper 8-10kg by original ton paper 10-15kg, has reduced ton paper applying glue cost.
The specific embodiment
Embodiment 1: neutral sizing agent is used for the technology that add on the surface; Interpolation step and addition to change neutral sizing agent are realized; It is characterized in that: pump into neutral sizing agent in the surface glue holding vessel with measuring pump; Mix the back is applied to into paper at the surface size press place surface with glue, the surface glue percentage is 8%, and neutral sizing agent is a 10kg/ ton paper.Through checking: the retention of neutral sizing agent is 85%, and the curing time is 6h, has improved 75%, has reduced bacterium and microorganism in the slurry.
Embodiment 2: neutral sizing agent is used for the technology that add on the surface; Interpolation step and addition to change neutral sizing agent are realized; It is characterized in that: pump into neutral sizing agent in the surface glue holding vessel with measuring pump; Mix the back is applied to into paper at the surface size press place surface with glue, the surface glue percentage is 10%, and neutral sizing agent is 8/ ton of paper.Through checking: the retention of neutral sizing agent is 82%, and the curing time is 6h, has improved 75%, has reduced bacterium and microorganism in the slurry.
Embodiment 3: neutral sizing agent is used for the technology that add on the surface; Interpolation step and addition to change neutral sizing agent are realized; It is characterized in that: pump into neutral sizing agent in the surface glue holding vessel with measuring pump; Mix the back is applied to into paper at the surface size press place surface with glue, the surface glue percentage is 9.5%, and neutral sizing agent is 9/ ton of paper.Through checking: the retention of neutral sizing agent is 83%, and the curing time is 6h, has improved 75%, has reduced bacterium and microorganism in the slurry.
