Abstract

The recovery method of photosensitive material of the present invention, directly use any part of plant, added water logging 1～15 day, add more bubble number minute again, filtering the back steeps waste sensitive material in the filtrate, normal temperature is placed a few hours down and is taken off from the sheet base fully with regard to the light-sensitive surface that easily will give up, and silver and plate substrate material are all recycled.The water that embathed the bean sprouts in also can directly producing with the bean sprouts soaks waste sensitive material.The present invention does not need insulation and ventilates, and does not need chemical reagent or biological reagent yet, and the cost that reclaims one ton of scrap rubber sheet is reduced to below 50 yuan.

Description

The recovery method of waste sensitive material

The present invention adopts biological method that waste sensitive material is carried out comprehensive utilization method at chemical field.

Unavoidable scrap rubber sheet, useless printing paper, the useless wet version etc. of doing of producing in processes such as the test of photosensitive material, production, storing, use, silver in its light-sensitive surface and plate substrate material all are worth recycling.But reclaiming silver-colored commercial run from scrap rubber sheet and useless printing paper now, generally is that useless sheet is incinerated, and refines silver again from ash.This method has been burnt the plate substrate material, is the waste to resource, and the flue dust of being discharged has severe contamination to environment.Original light-sensitive surface that will give up is taken off the method that silver and plate substrate material are reclaimed respectively (to be had one piece of article to report as " chemistry world " 1987 the 4th phases and uses chemical reagent, there is an article introduction finished product proteinase " scientific and technical information " 1989 the 5th phases), all need with expensive material and facility, cost recovery is higher.

The objective of the invention is to make the method cost that removes useless light-sensitive surface to reduce, and be convenient to implement with industrial scale.

Concrete grammar of the present invention is, the any part (root, stem, leaf, skin, seed and young shoot) of plant is soaked number with suitable quantity of water, add suitable quantity of water again and soak filtration after several minutes, in filtrate, immerse waste sensitive material, leave standstill just visible useless light-sensitive surface local shedding of a few hours under the normal temperature, is stirred again or brushing just can make the light-sensitive surface that gives up separate fully with the sheet base.The sheet base is cleaned and is dried, and the useless light-sensitive surface in the aqueous solution after the immersion is smelted into silver again after precipitation, filtration, drying.

Used plant is bright in this way, and outer amount of water is 1～100%(weight); If plant is done, then amount of water is 100～600%(weight), immersion through 1～15 day, the bubble 1～5 minute that adds 5～50 times of weight again, filter back with this aqueous solution soaking waste sensitive material, waste sensitive material by below the complete immersed in liquid level of original shape, was left standstill 2～100 hours.Handle waste sensitive material with the aqueous solution after the dry bean immersion, the beans after using or the bean sprouts of generation be edible still.Also available aqueous solution of embathing plant plumule is handled waste sensitive material.

The recovery method of waste sensitive material of the present invention, technology is easy, does not need insulation and ventilation, do not need chemical reagent or biopreparate yet, silver and plate substrate material are all recycled, and the plate substrate material needn't shred, but full wafer reclaims, and the cost that reclaims one ton of scrap rubber sheet is reduced to below 50 yuan.To handle one ton of useless black and white film is example: consume 500～1000 kilograms in hay, or 100～300 kilograms of dry beans (also can eat as usual with beans later or the bean sprouts of being given birth to), can get 650～800 kilograms in plate substrate material, 10～30 kilograms of silver.Only reclaim the plate substrate material for the scrap rubber sheet of argentiferous not remarkable economic efficiency is also arranged.

Be the most preferred embodiment of the inventive method below:

Embodiment 1:30 gram extra dry white wine Poplar leaves adds 50 gram water loggings 3 days, add 60 gram bubbles 5 minutes again, filter, in filtrate, immerse the useless K mating plate of 60 grams, put and saw that some position film had come off in one day, all the other position waters have come off once washing, and the sheet base is cleaned dried to such an extent that mylar 32 restrains, supernatant liquor is removed in washing lotion sedimentation hypsokinesis, with the precipitum evaporate to dryness smelt silver-colored 1.3 the gram.

Embodiment 2:10 restrains dried mung bean and adds 600 gram water loggings bubbles 1 day, and it is filtered in another basin, and each 40 gram of useless black and white film and useless black-and-white photograph are easy to just the sheet base cleaned next day bubble on, get cellulose acetate film 29 after drying and restrain, and blank sheet of paper 34 restrains.Continue thing through separation, dry, molten refining, get silver-colored 0.8 gram.It is edible that mung bean continues to generate the tall scrawny person.The aqueous solution of soaking the bean sprouts in the process of living bean sprouts still can be used for soaking waste sensitive material makes its demoulding.

Claims

1, the recovery method of waste sensitive material, the light-sensitive surface that will give up comes off silver and plate substrate material is recycled respectively, feature of the present invention is directly to utilize any part and the water effect of plant, use the aqueous solution soaking waste sensitive material of gained again, after useless light-sensitive surface comes off fully, the plate substrate material is cleaned and is dried, and the aqueous solution after the immersion can smelt silver after precipitation, filtration, drying;

2, the method for claim 1, outer amount of water is 1～100%(weight when it is characterized in that with the fresh plant body), outer amount of water is 100～600%(weight during with dried plant), the bubble 1～5 minute that adds 5～50 times of weight again, filter the back and in filtrate, the original shape of waste sensitive material is immersed fully, left standstill 2～100 hours;

3, the method for claim 1 is characterized in that handling waste sensitive material with the aqueous solution after the dry bean immersion, and the beans after using or the bean sprouts of generation be edible still, and also available aqueous solution of embathing plant plumule is handled waste sensitive material.
