Description
Technical field
The invention belongs to pulp technology for making paper, more particularly to a kind of paper technology of one side Blue Engineering paper.
Background technology
In reconnaissance projecting trade, the drawing that engineering construction project is used and owner's unit is filed externally is supplied to for a long time
It is one 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
Dry in the sun master is utilized；The Main Function of blueprint is to construction and files for consulting.Everybody gets used to this operator scheme, so
And, blueprint be difficult long-term preservation, it is of long duration will turn yellow, fade, getting wet obscure；The abnormal smells from the patient pole of discharge ammonia or developer solution
It pollutes environment and has a strong impact on the occupational health of practitioner；Work efficiency is low, densely populated place, day the drawbacks of high cost
Benefit appears.Therefore, the substitute for finding blueprint has become problem of concern.
Enter into the nineties in 20th century, global IT technologies obtain that flourishing and at full speed development, CAD collaborative designs etc. are new to be set
Meter means are more applied in survey and design industry with workflow management mode, in terms of drawing, because people pursue higher life
Efficiency and more smooth design conception are produced, a kind of new drawing publishing way --- " white figure " is published and arisen at the historic moment.It is " white
Figure " is the concept for blueprint, but it not exclusively instead of traditional blue printing paper with the difference of blueprint with " blank sheet of paper ",
The essence that white figure is published is to get rid of blueprint link, realizes directly printing using e-file and publishes engineering drawing.By printing
Mode and the white figure that produces gradually starts to replace blueprint status, the design drawing for becoming main to be formed.
Now the white drawing of the engineering of domestic production at present can be divided three classes：Blue Engineering paper, one side Blue Engineering paper, white work
Journey paper.
Current double side blue, white engineering paper technology it is relatively higher, but the technical merit of one side Blue Engineering paper
It is relatively lower.It is main at present to supply agent Hangzhou friendship ties, the suitable client such as Bo Hui peaks and Shanghai, Jiangsu, to one side blueness work
Journey paper has carried out the market survey in the area such as north, upper, wide, and one side Blue Engineering paper application is that engineering prints drawing, market
Prospect is very huge.At 40,000 tons or so, the product has higher added value to domestic demand amount, improves company's kind knot
Structure, is that enterprise participates in market competition, and widens Sales Channel and lays a good foundation, and after the quality of production is stable import blue printing paper can be replaced,
Increase foreign exchange earnings from exports, improve competitiveness in the international market and occupation rate.
One side Blue Engineering paper needs to carry out special coating process, and recto is white, and reverse side of paper is into client institute
The blueness of requirement, thus it is higher to the requirement of blue figure layer, and the coating and preparation technology level of prior art is relatively low, although have
Papery uniform ground, ink diffusion is serious, although the absorbency having is better, but figure layer is unstable, and warpage is serious, Er Qiexu
Through sub- light step, required flatness and the uniformity is can be only achieved, good calender is expensive and is easily affected by figure layer, damages
Hinder equipment.Therefore, in the case of without sub- light, reach one side indigo plant engineering paper is that those skilled in the art grind into 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 applied to low weight paper,
And ink absorbs relatively low, one side indigo plant engineering paper is not suitable for.
One side indigo plant engineering paper is different from common coating paper, and one side indigo plant engineering paper is beaten with drawing apparatuss due to needing in its blue face
Print is drawn, it is therefore desirable to paper is smooth, blueness faces instrument not damaged, the characteristic such as absorbency is good, while and being made for engineering
With, therefore rewinding, deflection, folding etc. require also higher, add that usage amount is big, cost is difficult too high.
At present one side Blue Engineering paper has following defect：（1）Coating ink absorbance 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 during printing.
The content of the invention
The present invention provides a kind of one side Blue Engineering paper and its preparation technology, to reach following purpose：
1st, the coating ink absorbance of one side indigo plant engineering paper, ink indiffusion during inkjet printing are improved；
2nd, improve the paper permeability of one side indigo plant engineering paper, reduce hygroscopicity value, improve formation of sheet, paper absorbs equal after coating
Even, paper does not grow dim.
3rd, control one side Blue Engineering paper moisture and web moisture profile is poor, paper not foldover, non-warpage after printing.
