Description
Technical field
The invention belongs to pulp technology for making paper more particularly to a kind of paper technologies of single side Blue Engineering paper.
Background technology
In reconnaissance projecting trade, it is externally supplied to the drawing that engineering construction project uses and owner's unit is filed for a long time
It is single side Blue Engineering paper, the drawing of designing unit's filing is base map and blueprint.The main function of base map be archive backups and
Solarization master utilizes；The main function of blueprint is to construction and to file for access.Everybody gets used to this operation mode, so
And blueprint be not easy long-term preservation, will turn yellow over time, fade, get wet it is i.e. fuzzy；Discharge the smell pole of ammonia or developer solution
Its occupational health for polluting environment and seriously affecting practitioner；Working efficiency is low, densely populated place, cost excessively high drawback day
Benefit appears.Therefore, the substitute for finding blueprint has become project of people's attention.
It enters in the 1990s, whole world IT technologies obtain flourishing and at full speed development, CAD collaborative designs etc. are new to be set
Meter means are more applied with workflow management mode in survey and design industry, in terms of drawing, since people pursue higher life
Efficiency and more smooth design conception are produced, a kind of new drawing publishing way --- " white figure " is published and is come into being.It is " white
Figure " is concept for blueprint, but the difference of it and blueprint is not only with " blank sheet of paper " instead of traditional blue printing paper,
The essence that white figure is published is blueprint link to be got rid of, and realizes and electronic document printing is directly utilized to publish engineering drawing.Pass through printing
Mode and produce it is white figure gradually start replace blueprint status, become main design drawing and formed.
The white drawing of domestic production engineering can be divided into three classes at present now：Blue Engineering paper, single side Blue Engineering paper, white work
Journey paper.
Current double side blue, the technology of white engineering paper are relatively higher, but the technical merit of single side Blue Engineering paper
It is relatively lower.Main supply agent Hangzhou friendship ties, the suitable clients such as the peaks Bo Hui and Shanghai, Jiangsu at present, to single side blue work
Journey paper has carried out the market survey in the area such as north, upper, wide, and single side Blue Engineering paper application field is engineering printing drawing, market
Foreground is very huge.For domestic demand amount at 40,000 tons or so, which has higher added value, improves company's kind knot
Structure is participated in market competition for enterprise, is widened Sales Channel and is laid a good foundation, and the quality of production can replace import blue printing paper after stablizing,
It increases foreign exchange earnings from exports, improves competitiveness in the international market and occupation rate.
Single side Blue Engineering paper needs to carry out special coating process, and recto is white, and reverse side of paper is at client institute
It is required that blue, therefore blue figure layer is required relatively high, the coating and preparation process level of the prior art is relatively low, although having
Papery uniform ground, ink diffusion is serious, although the absorbency having is better, but figure layer is unstable, and warpage is serious, Er Qiexu
By matt step, required flatness and the uniformity are can be only achieved, good calender is expensive and is easily influenced by figure layer, damages
Hinder equipment.Therefore, without matt, reach single side indigo plant engineering paper is that those skilled in the art grind at paper requirement
The important topic studied carefully.
Patent 001108530 provides a kind of production method of high-grade featherweight coated paper, discloses a kind of coating paper
Production technology, paper-forming evenness, smoothness, printing ink absorption etc. are made that larger raising.But the product is suitable for low weight paper,
And ink absorption is relatively low, is not suitable for single side indigo plant engineering paper.
Single side indigo plant engineering paper is different from common coating paper, and single side indigo plant engineering paper is beaten with plotter in its blue face due to needing
Print is drawn, it is therefore desirable to the characteristics such as paper is smooth, and blue is not damaged in face of instrument, and absorbency is good, while made for engineering again
With, therefore the requirements such as rewinding, deflection, folding are also higher, in addition usage amount is big, cost is not easy excessively high.
Single side Blue Engineering paper has following defect at present：（1）Coating ink absorptivity is not high, ink diffusion after printing；
（2）Evenness is poor, poor air permeability, and paper shade differs after coating, and painting is spent serious；（3）Foldover, warpage when printing.
Invention content
A kind of single side Blue Engineering paper of present invention offer and its preparation process, to reach following purpose：
1, the coating ink absorptivity for improving single side indigo plant engineering paper, ink indiffusion when inkjet printing；
2, it improves the paper permeability of single side indigo plant engineering paper, reduce hygroscopicity value, improve formation of sheet, paper absorbs after coating
Uniformly, paper not floating.
3, it controls single side Blue Engineering paper moisture and web moisture profile is poor, paper not foldover, non-warpage after printing.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
A kind of paper technology of single side Blue Engineering paper, step include：Slurrying, prepares surface glue, applies mixing papermaking
