Sensitive material is divided into black and white sensitive material and color sensitive material.Prepared by the Emulsion of color sensitive material include former breast
Preparation and oil breast preparation, preparations of former breast refer to the preparation of emulsion, and the newborn preparation of oil refers to the preparation of colour coupler.Sense
X-ray emulsion X production method is mainly comprised the following steps with liquid, emulsifying, physical ripening, desalination and chemical ripening.Desalination is emulsion life
An important step during product.Emulsion after emulsifying and physical ripening, in Emulsion containing substantial amounts of potassium nitrate and
Excessive halide salt, the presence of these salt will have a strong impact on the quality of chemical ripening and final photographic film, it is therefore necessary to by this
A little salt are removed, and the salt content per a collection of emulsion must be consistent.
Traditional desalinating process carries out desalination using cutting WATER-WASHING METHOD, i.e.,：Emulsion Jing after emulsifying and physical ripening is put
Enter in 0-5 DEG C of refrigerator tray and freeze 2 hours or so, make Emulsion be frozen into the jelly thin layer that thickness is 7-10cm, then by jelly
Emulsion carry out cutting and washing.This cutting WATER-WASHING METHOD requires that the Emulsion of manufacture must contain higher gelatin amount, if contained
Glue amount is not enough, generally requires a certain amount of gelatin is added after emulsifying and physical ripening, preferably could freeze in flakes.Using
This cutting WATER-WASHING METHOD carries out desalination, and which has the disadvantage unstable to the control of salt content, and water consumption is big, cumbersome,
High labor intensive, washing time are long, and the Emulsion gelatine content for obtaining is high, are not suitable for the requirement of the high speed thin-layer coating in modern times.
In view of traditional desalinating process has above-mentioned various shortcomings, people are improved to desalinating process.It is de- after improvement
Salt technique carries out desalination using sedimentation WATER-WASHING METHOD, specially：First the Emulsion Jing after emulsifying and physical ripening is lowered the temperature and adjusted
Its pH value is saved, then adds precipitant toward inside Emulsion, make Emulsion and gelatin coprecipitation get off, and water miscible salt in Emulsion
Then stay in supernatant liquid；Again by the liquor abstraction of upper strata salt concentration；Then add water and remaining Emulsion is washed, precipitate
After extract supernatant liquid out（Washing, precipitation, the process of extraction supernatant liquid can carry out one or many according to practical situation）, make breast
Salt content in agent is reduced in the range of regulation.Sedimentation WATER-WASHING METHOD is easily controlled with salt content compared with cutting WATER-WASHING METHOD
System, equipment are simple, operate the low advantage of simple, with short production cycle, labor intensity.
In sedimentation WATER-WASHING METHOD, supernatant liquid is extracted（Absorb water）It is an important step.When being absorbed water, should avoid suctioning out

Water pipe head connects the water inlet end of suction hose, and the water side of suction hose connects the water inlet of water pump.Suction head is put into during water suction
In supernatant liquid, supernatant liquid after starting water pump, can be extracted；As supernatant liquid is gradually sucked out, suction head is gradually reduced,
Until reaching solid-liquid interface.However, as suction hole is located at suction head bottom, when suction head absorbs water, liquid is flowed into from bottom to top
In suction head cavity, therefore, after most of supernatant liquid is sucked out, when suction head is close to solid-liquid interface, the breast of lower floor
Agent is easily sucked out with current, so, to thoroughly extract supernatant liquid, is then easy to simultaneously by the Emulsion sucking-off of lower floor, and
Emulsion to avoid lower floor is sucked out, then with a certain distance from suction head needs to have from solid-liquid interface, it is difficult to thoroughly by upper liquid
Body is suctioned out, so as to cannot take into account thoroughly by supernatant liquid suction out and while avoid suctioning out the Emulsion for being deposited in lower floor and gelatin this
Both sides is required.In addition, emulsion production at present is all carried out under safelight lamp, the safety that sedimentation washing desalination stage is used
Lamp is the red light of Weak-luminescence, and human eye is more difficult under such circumstances tells solid-liquid interface（Particularly demarcate in solid-liquid
When face is not fairly obvious）, it more difficult to grasp suction head position finally to be reached.
