Description
Technical field
This utility model relates to the triage techniques field of ammonium chloride anti-caking agent, especially relates to a kind of fast screening devices for ammonium chloride anti-caking agent.
Background technology
Ammonium chloride is that a kind of hygroscopicity is strong, the easily salt of caking.Caking is mainly due to the change of weather conditions, following two process is made constantly to carry out on ammonium chloride crystals surface and be formed: the moisture content during 1. ammonium chloride absorbs air, cause the dissolving of ammonium chloride, it is made to form saturated solution on the surface of ammonia chloride crystal (if wet ammonium chloride product, between its crystal, inherently with the presence of the saturated solution of ammonium chloride), 2. the evaporation of moisture content in the saturated solution of ammonium chloride surface, and owing to the decline of temperature makes the dissolubility of ammonium chloride reduce, all make ammonium chloride separate out from the saturated solution of crystal surface.Due to above-mentioned dissolving one crystallization process constantly on ammonia chloride crystal surface alternately, make constantly to occur on ammonia chloride crystal surface the process of ammonium chloride recrystallization, these newly-generated crystallizations have played the effect of " crystallization bridge " between the crystal grain of ammonium chloride, make between ammonia chloride crystal granule adhered to one another, eventually formed close bulk.
Carry out long-term research and practice for the problem of ammonium chloride from caking, domestic and international experts and scholars and manufacturer, proposed and used multiple anti-caking method, mainly having: seasoning, comminution granulation, waterproof bag method, medium crystallization agent method and anticaking agent method.And anticaking agent method is method the most simple and practical in all anti-caking methods, preventing blocking effect is best, and cost of investment is minimum, thus the most the most frequently used.
Anticaking agent method refers to use surface spraying in the production process of ammonium chloride (usually on belt conveyer or at centrifuge retaining ring) or be directly added into anticaking agent; fully it is mixed evenly through pneumatic conveying drying; and one layer of hydrophobic protecting film is formed on ammonia chloride crystal surface; it had both prevented ammonium chloride product and extraneous moisture exchange; there is again the generation hindering crystal " bridging " to act on during recrystallization process on ammonium chloride crystals surface, finally prevent ammonium chloride from caking.
At present, the method measuring preventing blocking effect is a lot, and applying more has cracking pressure method and stacking method.Cracking pressure method: sample is placed in particular manufacturing craft, the cylinder test block that forming under the pressure is Φ 30x60mm at 15MPa, it is subsequently placed in the calorstat that humidity is 80% 16h that quickly lumps, then move to the baking oven of 65 DEG C is dried 8h, the most in triplicate, put 16h then at ambient temperatare, measure the cracking pressure of test block with WE-10 type intensity measuring device.Cracking pressure is the lowest, and preventing blocking effect is the best.Stacking method: bag sample is stacked by 10 bag of one buttress, after certain time, sample is freely dropped into ground surface platform from 1m height level and falls bag, positive and negative each the most once, then with industrial screen (aperture 5mm), sample is sieved 1 minute, finally weighs the weight of residue on sieve.To sieve, mass percent number represents shatter value, and shatter value is the highest, and preventing blocking effect is the best.The cracking pressure method time is short, but actually used in due to operating process complex, experimental data error is relatively big, the less employing of general factory.Stacking method advantage is to be applicable to field application test, the data that preventing blocking effect can be described can be obtained, but shortcoming is the consuming time oversize (typically need at least stack more than 1 month), it is difficult to keep experimental condition (such as temperature, humidity etc.), and stack experiment every time and need a large amount of ammonium chloride and anticaking agent to test, Financial cost is higher.
Knowable to narration above, the equal Shortcomings of method of existing mensuration preventing blocking effect: as complex in cracking pressure method experimental implementation, data have certain error；Stacking method is the most oversize, and Financial cost is higher, and both approaches is all to be added in ammonium chloride by anticaking agent, then by measuring ammonium chloride relevant nature, thus indirectly draw anticaking agent using effect.For Formula Development worker, the formula adjustment cycle is oversize, is unfavorable for shortening the construction cycle.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is that offer one is simple to operate, with low cost, the consuming time is short, and directly can characterize the test device of anticaking agent usefulness.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
The technical program is a kind of fast screening devices for ammonium chloride anti-caking agent, including eyepiece, lens barrel, object lens, U-bracket and workbench；Described eyepiece is connected by lens barrel with object lens；Described lens barrel is fixedly mounted on U-bracket；Workbench is fixedly mounted on the described U-bracket relative with object lens；Coarse adjustment handwheel and trimming hand wheel it is fixedly installed on described U-bracket；The amplification of eyepiece is adjusted by coarse adjustment handwheel；The amplification of object lens is adjusted by trimming hand wheel.
As optimization, described workbench bottom is provided with leveling bolt, and leveling bolt is for adjusting the height of workbench.
As optimization, the external plexiglass tent of described workbench, plexiglass tent can effectively prevent wind to the interference of detection and preventing rocking of anticaking agent liquid.
Compared with prior art, the beneficial effects of the utility model are: this utility model is simple to operate, with low cost, it is short to expend the time, and directly can characterize anticaking agent usefulness.By measuring the ammonium chloride anti-caking agent wetness degree on ammonium chloride surface, reach the purpose of rapid screening anticaking agent, thus improve the ammonium chloride anti-caking agent Formula Development cycle.
