Abstract
The invention provides a kind of fingerprint acquisition instrument that improves and gather method and the Coating Materials of percent of pass.What the present invention provided improves the method for fingerprint acquisition instrument collection percent of pass is: with the block glue added with catalase, fingerprint collecting district being carried out plated film, the volume ratio of described block glue and catalase is 40 60: 0.01, and the thickness of plated film is 0.5 5mm.What the present invention provided improve fingerprint acquisition instrument gathers the Coating Materials of percent of pass, is in described method the used block glue added with catalase, or be described block glue the most unmixed with described catalase together with double-component combined material.The present invention can improve the fingerprint collecting percent of pass of fingerprint acquisition instrument, is particularly suited for dry environment.The method technique that the present invention provides is simple, easy and simple to handle, not only improves fingerprint collecting percent of pass, and product can be made to obtain splendid brightness, color and luster and wearability, and relative to similar products, cost performance is high.
Description
Technical field
The present invention relates to a kind of fingerprint acquisition instrument that improves and gather method and the Coating Materials of percent of pass.
Background technology
Live Fingerprint Collecting Instrument present stage expands application on a large scale the most throughout the country, but China accounts for
Ground area is wide, various places climate difference is bigger, causes fingerprint collecting to there are following 2 subject matters.
1) humid area: owing to humidity is relatively big in air, gathers in fingerprinting process and arise that streakline is overweight,
Obscure the problems such as a piece of.
2) Arid Area: due to dry, it is impossible to smoothly normal acquisition fingerprint, need to by washing one's hands,
The mode smearing hand oil is acquired.
The most above-mentioned the second, owing to air is dried, can not to gather the situation of fingerprint smoothly the most common, very
It is necessary to provide and can improve the method that fingerprint acquisition instrument gathers percent of pass.
Summary of the invention
It is an object of the invention to provide a kind of fingerprint acquisition instrument that improves and gather method and the plated film material of percent of pass
Material.
What the present invention provided improves the method for fingerprint acquisition instrument collection percent of pass is: with the block glue added with catalase
Fingerprint collecting district carries out plated film, and the volume ratio of described block glue and catalase is 40-60: 0.01.
The volume ratio of described block glue and catalase is preferably 45-55: 0.01, and more preferably 50: 0.01.
The thickness of described plated film can be 0.3-3mm, preferably 1-2mm.
The method dried after can using directly coating carries out plated film.
The main component of described block glue is preferably MTES oligomer.
Described block glue preferably Beijing China of state prosper together chemical products Co., Ltd produce camphane section glue
231-1。
The main component of described catalase is preferably dibutyl tin laurate.
Described catalase is preferably and is produced by Anhua, Beijing three chemical product Co., Ltd.
What the present invention provided improves the Coating Materials of fingerprint acquisition instrument collection percent of pass, is any of the above method
In the used block glue added with catalase, or be described block glue the most unmixed with described catalase together with
Double-component combined material.
Block glue for improve fingerprint acquisition instrument gather percent of pass purposes also within scope,
This purposes is described block glue for any of the above method.
The present invention can improve the fingerprint collecting percent of pass of fingerprint acquisition instrument, is particularly suited for dry environment.This
The method technique that invention provides is simple, easy and simple to handle, not only improves fingerprint collecting percent of pass, and can make product
Product obtain splendid brightness, color and luster and wearability, and relative to similar products, cost performance is high.
Detailed description of the invention
The present inventor is carried out by the proportioning to the transparent colloid of numerous species and with other reagent
Test, it is thus achieved that technical scheme.Below the preferred embodiment of the present invention is illustrated.
In following example, the fingerprint acquisition instrument used is Beijing Orient Jin Zhi Science and Technology Ltd.
A2000 type fingerprint acquisition instrument, the block glue used is that Beijing China of state prospers together chemical products Co., Ltd
The camphane section glue 231-2 (viscosity is 5000-10000) produced, described catalase is that Anhua, Beijing three chemical product is limited
The catalase that responsible company produces with dibutyl tin laurate for main component.
1) glass of fingerprint acquisition instrument acquisition window is carried out
2) camphane section glue and catalase are stirred about 2 minutes with the ratio of 50ML: 0.01ML, in stirring
During should be noted and do not drop any foreign matter in section glue.
3) after glass surface parches completely, the camphane section glue being stirred uniformly is filled glass surface about 1-2mm
4) glass having plated film is placed in dustless space, it is to avoid fall into dust
5) placement can use after section glue parches completely for 3-4 days.
The collection effect of the fingerprint acquisition instrument after utilizing said method to process is the best, and the production cycle closes the most very much
Suitable.Production cycle is: this process form of plated film before plated film to the production process after plated film and wait glass
The cycle of glass skin covering of the surface solidification.
Other similar colloids and all effects with said ratio method exist significant difference with the mixing of catalase
(percent of pass difference is generally between 5%-15%), prospers together the limited duty of chemical products even being all Beijing China of state
Other section of glue-type number [such as section glue 231-1 (viscosity is 1-5000), the camphane section glue that Ren company produces
232-3 (viscosity is 10000-50000)] in said method, effect is also had a greatly reduced quality.The side of the present invention
Method technique is simple, easy and simple to handle, not only improves fingerprint collecting percent of pass, and product can be made to obtain splendid light
Brightness, color and luster and wearability, relative to similar products, cost performance is high.
Fingerprint acquisition instrument after utilizing method described in above example to process carries out some experiments of fingerprint collecting
Data are as shown in the table:
As seen from the above table, gather the disposable percent of pass of fingerprint after plated film (after i.e. utilizing the method for the present invention) to obtain
Significantly improve.
