Description
Technical field
The invention belongs to pulp technology for making paper, be specifically related to a kind of ITO electropane protective paper and preparation method.
Background technology
21 century is the information age, various types of flat panel display as Message Display Terminal has entered into each face of social life, thus the ITO electropane demand being used as to make flat-panel monitor is also increasing, just there is the production line more than 70 producing ITO electropane in current China, produces various ITO electropane about 3,000 ten thousand square metres per year.The major parameter of ITO electropane is sheet resistance and uniformity, light transmittance etc.; therefore; protective paper for ITO electropane can not affect the above-mentioned major parameter of ITO electropane; and ITO electropane protective paper protects use under ITO electropane is also in hot situation, so the particulate of any conduction on protective paper or dust is all as easy as rolling off a log is bonded at the sheet resistance and uniformity, light transmittance that affect ITO electropane above it.Though China has many to produce plate glass mildew-resistant interleaving paper, glass every lining paper, the plate glass mildew-resistant interleaving paper that they produce, glass are not suitable for the protective paper making ITO electropane every lining paper.
Summary of the invention
The object of the invention is the situation in order to change above-mentioned prior art; a kind of ITO electropane protective paper and preparation method are provided; the ITO electropane protective paper produced by the method; do not have the particulate of conduction or dust stick-down on ITO electropane; affect sheet resistance and the major parameter such as uniformity, light transmittance of ITO electropane; for packing, liner, good every the protection effect of lining ITO electropane, and low cost of manufacture.
Above-mentioned goal of the invention is achieved through the following technical solutions:
A kind of ITO electropane protective paper, comprise the hard copy body that string is made, its main points are, hard copy weight is in 100, then the content of iron is not more than 0.002%, and the content of manganese is not more than 0.00003%, and the content of chlorine is not more than 0.01%; Tightness is no less than 0.5g/cm3; Quantitative franchise+2 ~-2g/ ㎡; Tearability is on average no less than 40mN in length and breadth; Gas permeability be not less than 25 μm/(pa.s); The no more than 2 Ge/㎡ of dirt count.
A preparation method for ITO electropane protective paper, is characterized in that it comprises the following steps:
A, paper making water to be purified, removes the impurity in paper making water and metal ion:
First former water is entered tube settling, ventilative to permeability pool precipitation after reentering the filtration of smart yarn, then after activated carbon filtration, enter ventilative tower to mixed bed ventilative, finally enters negative and positive bed, put into clear water reserviors, namely reach deionized water after the ion-exchange of negative and positive bed; After testing in qualified rear feeding paper pulp and each process water; Effect is that the protective paper for making low ion and low conductivity is first from using control waterborne;
B, select coniferous tree or the fragmentation of wide leaf trees slurry pulper after send into broken after-bay, reenter regulating reservoir, mix up concentration and enter mill; Cut off with 1 group of mill, 2,3 groups of mill corase grind, 4,5 groups of mill fine grindings, grinding enters concentrated sieve after reaching the degree of beating needed for paper machine; Concentration reaches more than 5% and puts into machine chest, adds steam and carries out string expansion; Temperature reaches 30--60 DEG C, stores and within more than 48 hours, reaches string expansion; Enter husky device, pressurized screen after dilution, send into header box, then send into net cage, upper screen cloth is shaped; Enter drying cylinder again to dry, then enter reel cylinder and be shaped, then be cooled to hard copy body paper roll by reel cylinder.
As preferably, it is by respiratory dryer hood heating, drying that described drying cylinder is dried; Described respiratory dryer hood comprises the high master cylinder boot of temperature and the low secondary cylinder cover of temperature; Master cylinder boot is sent in master cylinder boot by two-way steam by hair-dryer, master cylinder boot temperature is increased, by air-introduced machine, cold wind is drawn again, make the flash baking of hard copy body, then hard copy body is transported to secondary cylinder low-temperature heat from master cylinder and enters reel cylinder shaping, then is cooled to hard copy body and ITO electropane protective paper paper roll by reel cylinder.
As preferably, described hard copy body paper roll is again through rewinding machine rewinding, and the hard copy body after rewinding is good enters ten thousand grades of dust-free workshops again to carry out cutting packaging.
The ITO electropane protective paper that the present invention produces; because reach above-described technical indicator; so do not have the particulate of conduction or dust stick-down on ITO electropane; affect sheet resistance and the major parameter such as uniformity, light transmittance of ITO electropane; for packing, liner, good every the protection effect of lining ITO electropane, and low cost of manufacture.So above-described technical indicator can be reached, because one is selected coniferous tree or wide leaf trees slurry; Two be add steam carry out coniferous tree or wide leaf trees slurry string fully expand, make to be mingled in any conduction in wood pulp string or nonconducting particulate obtains filling part separation with dust and string, and the content of the impurity such as self iron of the protective paper thus produced, manganese, chlorine, dust reaches the minimum of a value of prior art; Three be that drying cylinder dries is by respiratory dryer hood heating, drying, just can reach paper drying requirement without the need to high temperature, can not produce paper scrap, can not fiber adustion, thus effectively reduce the dirt content that paper can not be visual.
Detailed description of the invention
A kind of ITO electropane protective paper, comprise the hard copy body that string is made, hard copy weight is in 100, then the content of iron is not more than 0.0015%, and the content of manganese is not more than 0.000025%, and the content of chlorine is not more than 0.009%; Tightness is no less than 0.6g/cm3; Quantitative franchise+1 ~-1g/ ㎡; Tearability is on average no less than 41mN in length and breadth; Gas permeability be not less than 26 μm/(pa.s); The no more than 2 Ge/㎡ of dirt count.
A preparation method for ITO electropane protective paper, it comprises the following steps:
