Abstract
The invention relates to a method for ameliorating stickies in repulped stocks for making household paper, comprises the steps of diluting a talcum powder, adding the diluted talcum powder on an entrance of a fan pump of a paper machine, and adding the diluted talcum powder into the repulped stocks by pumping and pulp grinding, the addition amount of the talcum powder into the repulped stock is 5-10Kg/t. The advantages of the method over the prior art are as follows: improving quality and reducing economic loss directly.
Description
Technical field
The present invention relates to the paper grade (stock) regeneration slurry, especially relate to the manufacture paper with pulp method of sicker in the regeneration slurry of paper for daily use of a kind of improvement.
Background technology
The raw material that at present paper industry is commonly used is that primary bleached wood pulp, primary bleaching non-wood pulp material, regeneration bleached wood pulp, regeneration true qualities wood pulp are raw material.Paper for daily use adopts the primary slurry high-grade paper for daily use of manufacturing paper with pulp; Because the slurry source is complicated, and impurity is more in the slurry, impurity removal process is complicated for regeneration slurry (regeneration bleaching slurry and regeneration true qualities slurry); So regeneration slurry generally is applicable in the low and middle-grade paper products; Especially the true qualities of regenerating slurry is used for the lower wrapping paper of production added value more, less being applicable in the high-grade paper for daily use.The subject matter that regeneration slurry exists aborning has: the many impurity in the slurry can form sicker; Because the viscosity of sicker; Make it in system, produce deposition on some fixture; Send part etc. like pipeline, stock tank inwall, paper machine stream, the deposition on moving component mainly contains forming net, felt, roll surface etc.When on forming net, adhering to, can influence the drainage of net, on paper, form thin curtain and hole thoroughly, can directly cause disconnected paper and produce underproof product.Especially the paper for daily use of manufacturing paper with pulp is quantitatively on the low side, and the hole that sicker causes is bigger to the paper influence.And paper machine can't normally be produced continuously, must clean veil and felt by frequent shutdown, directly causes the production production capacity to reduce, and production loss is bigger.Generally speaking, the sicker in the regeneration slurry not only causes product quality problem, and brings serious economy loss to production.
Along with the shortage of the forest reserves, the reinforcement of environmental requirement, the supply day of primary slurry is becoming tight.Those skilled in the art are studying the preparation technology of the paper for daily use raw material of alternative more environmental protection energetically at present.
Summary of the invention
The object of the invention is exactly the method that sicker in the regeneration slurry that a kind of improvement that improves quality, directly reduces economic loss manufactures paper with pulp paper for daily use is provided in order to overcome the defective that above-mentioned prior art exists.
The object of the invention can be realized through following technical scheme: the manufacture paper with pulp method of sicker in the regeneration slurry of paper for daily use of a kind of improvement; It is characterized in that; Talcum powder is diluted; Be added on paper machine fan pump porch, add in the regeneration slurry through the pumping defibrination, described talcous addition is 5～10Kg/t regeneration slurry.
Described talcous order number is 800 orders.
Described talcum powder is diluted to 3～10wt% through water.
Compared with prior art, the present invention has following advantage:
1, uses regeneration slurry production, guarantee to produce qualified product after improving sicker, promote than before and guarantee product quality.
2, guarantee the normal running continuously of paper machine, the paper machine is shut down wash number and is reduced greatly, has promoted the papermaking production capacity.
3, directly reduce economic loss.
The specific embodiment
Below in conjunction with specific embodiment the present invention is elaborated.
Embodiment 1
The manufacture paper with pulp method of sicker in the regeneration slurry of paper for daily use of a kind of improvement is diluted with water to 8wt% with 800 other talcum powder of order level, uses the talcum powder of high order number to be adsorbed onto the surface of sicker; Can reduce its viscosity; Thereby avoid the absorption of sicker on each parts of paper machine, talcum powder through after being diluted to finite concentration, is prone to be blended in the slurry; Be adsorbed on the sicker surface in the slurry; Be added on paper machine fan pump porch after the talcum powder dilution, add in the regeneration slurry, because the effect of shearing forces such as the pumping of paper machine operation process, defibrination through the pumping defibrination; And the talcum powder anti-shear ability on the sicker is poor, can cause bigger cohesion in case come off.
Described talcous addition is the 8Kg/t regeneration slurry, after present technique is implemented, produces in the identical product, and downtime, more former technology reduced by 10%, and promptly production capacity promotes 10%.Produce finished product and all reach the product quality requirement, no defective products copies back.
Implement board: the Zhijiang River, river BF-10 machine
Implement kind: the 17gsm toilet paper
Product proportioning: 20% regeneration natural color pulp+80% reclaimed white slurry
Embodiment 2
The manufacture paper with pulp method of sicker in the regeneration slurry of paper for daily use of a kind of improvement; 800 other talcum powder of order level are diluted with water to 3wt%; Be added on paper machine fan pump porch, add in the regeneration slurry through the pumping defibrination, described talcous addition is the 5Kg/t regeneration slurry.
Embodiment 3
The manufacture paper with pulp method of sicker in the regeneration slurry of paper for daily use of a kind of improvement; 800 other talcum powder of order level are diluted with water to 10wt%; Be added on paper machine fan pump porch, add in the regeneration slurry through the pumping defibrination, described talcous addition is the 10Kg/t regeneration slurry.
Claims (3)
1. the improvement method of sicker in the regeneration slurry of paper for daily use of manufacturing paper with pulp; It is characterized in that,, be added on paper machine fan pump porch the talcum powder dilution; Add in the regeneration slurry through the pumping defibrination, described talcous addition is 5～10Kg/t regeneration slurry.
2. the manufacture paper with pulp method of sicker in the regeneration slurry of paper for daily use of a kind of improvement according to claim 1 is characterized in that described talcous order number is 800 orders.
3. the manufacture paper with pulp method of sicker in the regeneration slurry of paper for daily use of a kind of improvement according to claim 1 is characterized in that described talcum powder is diluted to 3～10wt% through water.
