Description
Technical field
The present invention relates to a kind of preparation method of stainless steel lining paper, particularly relate to a kind of method of utilizing waste paper for the feedstock production stainless steel lining paper, belong to pulp technology for making paper.
Background technology
Stainless steel lining paper be the stainless-steel cold-rolling thin plate roll, in pickling, smooth, reconditioning, the effect operation process such as refining; Prevent to draw and other damages because of slippage, high-tension, high temperature, friction cause to wipe between sheet-metal layers, fill up a kind of extraordinary industrial paper that shields at its interlayer to improve the cold-reduced sheet surface quality.High temperature resistant stainless steel technology packing paper requires to have higher surface strength, tensile strength and other physical strengths; Certain smoothness is arranged, and the dirt count of paper is controlled minimum as far as possible; It is neutral that paper is, and CL-content is less than 100mg/kg, and SO42-content is less than 150mg/kg; The evenness of paper is better, and thickness is even.Higher surface strength can prevent the hair and powder dropping of paper in rolling process; Higher physical property can guarantee that in use paper is unlikely to damage or sticks to stainless steel surfaces, particularly paper through after the reuse repeatedly, if intensity is bad, just goes wrong in the use repeatedly more easily.The evenness of paper is better, thickness is even, and helping paper has intensity preferably, guarantees that also the stainless-steel roll thickness that batches is even.Simultaneously paper should have absorbability preferably to oil, residual oil when being absorbed in cooling and lubricating steel plate in the rolling process.Through supercooling, the high temperature resistant stainless steel lining paper is involved in steel plate after steel rolling, needs anti-160 ~ 180 ℃ high temperature.Owing to shorten cool time, raising rolling mill speed, minimizing cooling metal sheets can reduce cost with oil, therefore the high temperature resistant stainless steel packing paper are proposed
New requirement, modern steel rolling process requires the high temperature resistant paper should anti-190 ~ 200 ℃, paper can not stick to surface of steel plate because of intensity decreases behind experience high temperature, paper contains lower CL-and SO42-, to reduce the corrosion to steel plate.Because under this temperature, degradation of fiber is relatively more severe, paper sticks to surface of steel plate easily and pollutes.
Because stainless steel lining paper has very high specification requirement; Generally all selecting needlebush and the hardwood pulp that intensity is high, resistance to elevated temperatures is good and CL-content is little for use at present is raw material; The proportioning softwood pulp: hardwood pulp 60%:40%, the softwood pulp beating degree is 59oSR, the hardwood pulp beating degree is 45oSR.Adopting needlebush and leaf wood is in the production process of feedstock production stainless steel lining paper; At first need use the making beating disc mill to pull an oar; For surface strength and the heat resistance that improves stainless steel lining paper; In the paper machine making process, need top sizing (coating) machine starch in applying glue and top sizing (coating).Adopting existing general culture paper machine is the production that can't accomplish above-mentioned stainless steel lining paper, need carry out corresponding transformation to general culture paper machine, and increase equipment, has therefore increased production cost, and has been unfavorable for producing fast.And, utilize needlebush and leaf wood to process the log slurry, need a large amount of timber of felling, the destruction of causing the forest reserves is unfavorable for the natural environment of protecting the mankind to depend on for existence.
Summary of the invention
The object of the invention is exactly that the weak point that is directed against above-mentioned prior art provides a kind of method of utilizing waste paper for the feedstock production stainless steel lining paper; Adopting 100% stainless steel lining paper waste paper fully is raw material; And need not to transform existing equipment and increase equipment, can solve the defective of above-mentioned existing preparation method's existence fully.
The objective of the invention is to realize through following mode: a kind of method of utilizing waste paper for the feedstock production stainless steel lining paper may further comprise the steps:
Step 1, adopting stainless steel lining paper waste paper is raw material, batches at paper machine that size degradation is a slurry in the broken pond,
Be stored in the broken tower;
Step 2, slurry stores through being pumped in the broken pond after discongesting;
Step 3 adds dry strength agent and guar gum in proportion in blending chest, be pumped to paper machine stock tank after the mixing;
Step 4, the slurry concentration of adjustment paper machine stock tank is 4%-5%, is pumped to the outer white water chest of paper then and is diluted to 1% concentration;
Step 5 is removed the gas in the slurry in deaerator, remove light, heavy seeds in the slurry through scummer and pressurized screen again, adds fire retardant and retention and drainage aid agent in proportion in the pressurized screen outlet;
Step 6, mashing pump deliver to flow box and paper machine is manufactured paper with pulp, and gets semi-finished product paper;
Step 7, semi-finished product paper cut into the stainless steel lining paper product of different size through rewinding machine by customer requirements;
Step 8, finished product stainless steel lining paper are sent into finished room and are sent to the user after the packing machine packing.
Further, paper machine batches and adds 2/3rds the water yield in the broken pond in the step 1, drops into a certain amount of stainless steel lining paper waste paper and carries out size degradation, guarantees that the slurry concentration that obtains behind the size degradation is 4%-5%.
Further, the addition of dry strength agent is 0.18%-0.22% (percentage by weight) in the step 3, and the addition of guar gum is 0.08%-0.12% (percentage by weight).
As preferably, said dry strength agent addition is 0.20% (percentage by weight), and the guar gum addition is 0.10% (percentage by weight).
Further, the fire retardant addition is 0.18%-0.22% (percentage by weight) in the step 5.
As preferably, the fire retardant addition is 0.20% (percentage by weight).
Further, pH7.0-7.2 in the flow box, concentration 1.%, beating degree 65-75 ° of SR.
As preferably, the raw material that is adopted in the step 1 is 100% stainless steel lining paper waste paper.
Compared with prior art, beneficial effect of the present invention is:
1) help environmental protection: the stainless steel lining paper waste paper of employing 100% replaces log to prepare slurry, thereby avoids a large amount of forest reserves to be cut down, the human natural environment of depending on for existence of protection;
2) energy savings: need not use the making beating disc mill to pull an oar, only need that stainless steel lining paper waste paper is carried out size degradation and can satisfy production requirement, practice thrift a large amount of electric energy that making beating is consumed, cut down the consumption of energy;
3) simplify technology, enhance productivity: in slurry, add dry strength agent, guar gum and fire retardant just can accomplish replacement starch in applying glue and top sizing (coating); The surface strength and the heat resistance requirement of stainless steel lining paper have not only been satisfied; And improved the tensile strength and the tearability equal strength index of stainless steel lining paper, and simplified production technology; Cancel top sizing (coating) step of slurry, avoided installation surface applying glue (coating) machine and problem that the production efficiency that causes reduces;
4) reduce production costs: producing stainless steel lining paper with the method for log slurry and top sizing (coating) need increase beating equipment; And the paper machine carried out big transformation; Installation surface applying glue (coating) machine; The drying capacity of original paper machine also can descend 15%, influences the speed of manufacturing paper with pulp of paper machine, and needs 1 month shutdown to transform the time.And adopt this patent method, general culture paper machine can produce stainless steel lining paper without transforming, and convenient, fast, and do not need investment for trnasforming urban land.
