Description
Technical field
The present invention relates to make the fluoroscopic method of X-ray, the x-ray image that is mainly used in the electrovacuum container shows.
Background technology
The phosphor screen manufacture method of using is in a vacuum all used the whole bag of tricks processing such as the precipitation method, spraying process, centrifugal process now.The large tracts of land phosphor screen all has the phosphor powder layer air spots, and the uniformity of image display brightness is had certain influence, and when the image display requirement was higher, influence is obviously aggravation also.
Summary of the invention
The purpose of this invention is to provide the fluoroscopic manufacture method of a kind of piezo-optical x-ray, to solve phosphor powder layer surface roughness and the unevenness problem of higher that existing large tracts of land phosphor screen exists.
It comprises the following steps the present invention,
A), mixed fluorescent powder, with granularity be the sulfide of 3～10 μ m or gadolinium oxysulfide terbium as fluorescent material, as adhesive, add 5～10 ‰ adhesive with KBr or potassium silicate in fluorescent material, the back that stirs is standby;
B), processing phosphor screen end liner, phosphor screen end liner 4 materials adopt metal or nonmetallic substance, can can process the phosphor screen end liner of the size geometry that varies in size according to the actual needs, make phosphor screen end liner two plane parallel degree error＜0.01mm up and down, bottom substrate plane surface roughness is 0.8-1.6, unevenness≤0.03mm;
C), decontamination handles, and adhesive is coated on the phosphor screen end liner that the surface cleaned up uniformly, carries out the decontamination processing with the surface that absolute ethyl alcohol and oxidant contact with phosphor powder layer the phosphor screen end liner; To guarantee the reliable firmly contact of following fluoresent coating;
D), with the tiling or spraying process the mixed fluorescent powder in a step is put into the phosphor screen end liner, fluorescent material thickness is 0.4-0.8mm; So that can guarantee that when press forming the thickness of phosphor powder layer is 0.1-0.4mm;
E), make compacting tool set, plane compacting drift is corresponding with phosphor screen end liner size, plane compacting punch head surface roughness is 0.4-0.8, unevenness≤0.03mm, two plane parallel degree error＜0.01mm about the plane compacting drift;
F), punching press, the phosphor screen end liner is heated to 40～60 ℃, press plane compacting drift, put into slowly pressurization on the hydraulic press table top, pressure is 10～150kg/cm
2, keep-uped pressure 3-4 hour, progressively reduce pressure then to normal pressure.To reduce the internal stress that metal material and fluorescent material work in-process produce, prevent the fluorescence coating fracture; Pressure is relevant with the area of phosphor screen end liner, and the area of phosphor screen end liner is little, and pressure is just little.
The present invention makes simply, process stabilizing, and control is convenient, can improve X light image quality under vacuum.This method has no effect to environment.
