Sour caesium, through experimental results demonstrate add a certain proportion of Schweinfurt green in ink and cesium acetate can to improve ink anti-to light
Penetrate ability, when Schweinfurt green is higher than 0.8%, ink occurs Topical Dispersion phenomenon, increasing with concentration, and the local of ink is divided
Scattered phenomenon can gradually be aggravated, and when Schweinfurt green is less than 0.8%, does not then have well to the effect improving ink luminous reflectanc,
When the concentration of Schweinfurt green is 0.8% about, not only can improve ink luminous reflectanc but also will not make ink that Topical Dispersion occurs
Phenomenon.And the effect of ink raising ink luminous reflectanc has its limit merely, calculate big to the reflectance of light through instrument
About highest brings up to 3% about it has been found that when being simultaneously introduced cesium acetate, the luminous reflectanc of ink is greatly improved, by original
3% bring up to 7.5% about, and simple only add a cesium acetate to be added without Schweinfurt green, the luminous reflectanc of ink has no and substantially carries
High.Because water conservancy diversion ball, liquid-collecting cover, h1, h2 and h3 are with reference to the approximate isosceles trapezoid in section making figure line, make the reflective area of figure line big
Big raising, in conjunction with the collective effect of cesium acetate and Schweinfurt green, can bring up to the luminous reflectanc of ink close to 10%.Xy work
Station makes paper move, and draws out geometric figure.The exhaust pump of the present invention can be firm by paper by pore and main through hole
Absorption is on ventilation seat, it is to avoid drawing is drawn inaccurate.The supporting plate of the present invention can balance paper in being tried hard to avoid that pore goes out
Exempt from paper excessive tensile, gas can be facilitated simultaneously to pass through.The present invention also has simple for structure compact, cheap for manufacturing cost and makes
With easy advantage.

A kind of mathematical education geometry paints instrument, as shown in Figure 1, Figure 2, Figure 3 and Figure 4, including fixed seat 9, fixed seat 9 upper
Xy workbench 8 and support 18 are installed by portion, and the fixed part of xy workbench 8 is coordinated with fixed seat 9, and the move portion of xy workbench 8 is installed
Ventilation seat 5 and exhaust pump 7, the inside of ventilation seat 5 opens up main through hole 6 and several pore 4, the lower end of several pores 4 all with
Main through hole 6 communicates, and the gas delivery port of exhaust pump 7 is connected with main through hole 6, and the upper end of several pores 4 is all upper with ventilation seat 5
Surface engagement, the upper end of pore 4 is communicated with the external world, the top setting paper 15 of ventilation seat 5, and pigment is installed on the top of support 18
Bucket 1 and electric putter 12, the push-pull bar of electric putter 12 is in vertical state, and the push-and-pull boom end of electric putter 12 installs liquid storing barrel 10, storage
Liquid-collecting cover 11 is installed in the bottom of liquid bucket 10, and liquid-collecting cover 11 is in inverted truncated cone-shaped structure, the upper interior of liquid-collecting cover 11 and liquid storage
The inside of bucket 10 communicates, and the bottom of liquid-collecting cover 11 opens up opening 14, and water conservancy diversion ball 13,13, water conservancy diversion ball are installed in the inside of liquid-collecting cover 11
Supporting plate 16 is installed in the top of opening 14, described pore 4, the upper surface of supporting plate 16 keeps phase with the upper surface of ventilation seat 5
Level state, has gap between supporting plate 16 and pore 4 inwall, described liquid-collecting cover 11 liquid-collecting cover 11 lower end and paper when being drawn
The distance opening 15 is h1, h1=0.097 millimeter, and the internal diameter of opening 14 is h3, h3=0.083 millimeter, the center of water conservancy diversion ball 13 and collection
The center overlapping of axles of liquid cover 11, water conservancy diversion ball 13 distance nearest with liquid-collecting cover 11 inwall is h2, h2=0.05 millimeter, liquid storing barrel 10
Interior splendid attire high definition ink.
High definition ink is grouped into by the group of following weight percentage:
Epoxy resin, 4%；
Polyester resin, 9%；
Defoamer, 2.1%；
Wearproof emulsion, 31%；
Solvent, 34%.
Pigment, 15%；

10%.Xy workbench 8, makes paper move, draws out geometric figure.The exhaust pump 7 of the present embodiment can be by pore 4 and master
Through hole 6 firmly adsorbs paper 15 on ventilation seat 5, it is to avoid drawing is drawn inaccurate.The supporting plate 16 of the present invention can be with balance paper
Open the stress going out in pore 4 and avoid paper excessive tensile, gas can be facilitated simultaneously to pass through.The sodium silicate of the present embodiment is permissible
Improve the adhesive force of ink, the phenomenon of ink Topical Dispersion can be avoided simultaneously further.
In the present embodiment, each component of ink can directly be buied from commercial channels.Epoxy resin and polyester resin are adopted
With hard resin, as such, it is possible to dissolve by using suitable solvent, such as adopt more environmentally friendly solvent.In addition, in choosing
When selecting solvent, printing type can be taken into account to select, can more easily control dry speed, if using bag
Include the liquid resin of quick-dry type solvent, then might have bad printing, for silk-screen or bat printing when constructing.
So the selection of both hard resins can avoid this shortcoming.In addition, epoxy resin and polyester resin use cooperatively and can make
The adhesive force obtaining ink is stronger, and more preferably, ink is also finer and smoother for wearability, can save ink in (in construction) practice.This
Outward, the copolymer with pigment affinity groups for the dispersant employing is so that dispersion effect is more preferable.Nano wearproof emulsion further enhances
The anti-wear performance of ink.The invention provides a kind of ink, it uses the epoxy resin of solid, polyester resin and wear-resisting
The components such as emulsion are so that the adhesive force of ink and wearability all greatly improve, and chemical resistance is also more preferable, paint also more refinement
Greasy, can significantly save ink in use.In the present invention, select more environmentally-friendly solvent so that ink is also more environmentally-friendly.Tree
Fat and solvent, all compared with environmental protection, meet European Union rohs and fda standard, and ink toasts after 1 ~ 2h through 70 ~ 90 DEG C, in elastic body surface
Face has excellent adhesive force, the excellent performance such as abrasion-resistant, ethanol-tolerant.Additionally, each composition of the ink of the present embodiment can be easy
Buy, preparation is also very convenient, has good application prospect.
