Description
Technical field
The invention belongs to aluminium preparation technical fields, and in particular to a kind of aluminium rolled lubricating oil filter aid proportion is quickly determining
Method.
Background technique
During aluminium rolling, ROLLING OIL not only act as lubrication, cleaning, it is cooling the effects of, and oxide, the aluminium generated
The dust etc. that falls into can all be rolled oil and take away in bits and air, if ROLLING OIL cannot be filtered effectively, with rolling
The progress of system, oily pollution will be increasingly severe, and then seriously affect the quality of product, it is therefore necessary to have to ROLLING OIL
The filtering of effect.Currently, most of producer is all to be filtered with leaf filter to ROLLING OIL, this filter is by means of filtering
Medium and filter aid are completed.Filter medium is filter paper, and filter paper need to carry filter cake, so filter paper will not only have centainly
Voidage, also to have certain intensity.Certain voidage guarantee ROLLING OIL by that filter aid particles cannot be allowed to leak through, one
Fixed intensity guarantees that fracture phenomena does not occur in filtering and cleaning process.In filter operation, in order to reduce filtration resistance, increase
Add the rate of filtration or obtain a kind of complementary granular substance that the clear filtrate of height is added, referred to as filter aid.It is common
The active carclazyte of filter aid, diatomite, bentonite, activated carbon, activated alumina, sawdust or lignocellulosic.Aluminium rolling enterprise
Generally by above-mentioned substance, two or more substance (filtration and suction-operated) is composed the filter aid of industry.Filter cake
Mechanical filter effect and the suction-operated of active material can make ROLLING OIL keep cleaning, therefore, the additive amount of various filter aids
Proportional, different ratio is answered, filter effect is different.The ratio of active material is bigger, and filtration time is slower.It is actually added into
Amount will also according to the difference of used various quality filter aids different from.Furthermore, it is contemplated that required by different milling trains
Oily filtering accuracy (should meet production, save again) is different, and the proportion of filter aid is also answered different.Actual production
In, the type and proportion of filter aid can only be according to previous knowhow, produced on-site tests or by the experience of other producers
It determines, the time not only needed in this way is long, low efficiency, and is not necessarily optimal proportion.So lacking one in actual production
The method that kind effectively can quickly determine aluminium rolled lubricating oil filter aid proportion.
Summary of the invention
The purpose of the present invention is to provide a kind of aluminium rolled lubricating oil filter aids to match fast determination method；A variety of filter aids
Its content is selected by Orthogonal Experiment and Design, live aluminum cold-rolling oil filtration system is simulated, controls crucial filtration parameter, evaluation is answered
With test result, method and step is simple and easy, effectively can quickly determine filter aid proportion, determine filter aid to actual production
Proportion has important guiding effect.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of aluminium rolled lubricating oil filter aid proportion fast determination method, comprising the following steps: filter aid is pressed into different content group
Precoated shet is formed in Vacuum filtration device at filter medium, controls precoated shet thickness.The filter medium of same ratio is a little
Filter cup filtering is slowly poured into after mixing with dirty oil, filter process controls filtering pressure, record filtering time, and filtered absolute oil is used
Spectrophotometer detects light transmittance.Proportion is determined with filtration time and the height of light transmittance percent change.
Specific steps include:
(1) design experiment scheme: different filter aid and content range are selected, according to Orthogonal Experiment and Design testing program.
(2) it prepares: pressing above-mentioned testing program, weigh different filter aids respectively with electronic analytical balance, be stirred into not
With the filter medium of weight ratio column, pour into beaker respectively.
(3) precoated shet makes: nonwoven filtration cloth (size is determined according to practical vacuum Suction filtration device) is inserted in vacuum filtration
On the filter core of device filter cup, for use；The mixed filter medium of 3.8 ~ 4.2g is weighed, is rolled with 40 ~ 60ml light transmittance 100%
Oil mixing, stirs evenly, slowly pours into filter cup along glass bar, forms certain thickness precoating filter cake (according to actual production
Filtration system filter cake thickness determines).
(4) it filters: weighing the mixed filter medium of 0.5g and mixed with the dirty oil of 50ml, (according to reality after several minutes of stirring
Filtration system ROLLING OIL flowing time is produced to determine), 100 ~ 200ml/min is poured into filter cup along glass bar, after being all finished down,
Vacuum pump is opened, vacuum pressure control is aspirated in 200mmHg, the record suction deadline, to illustrate to filter speed.
(5) light transmittance of absolute oil after being filtered with the detection of 722 type spectrophotometers, and light transmittance percent change is calculated, come
Illustrate filter capacity.
(6) compare light transmittance percent change and filtration time to determine that filter aid matches.Filtration time of pumping is shorter, mistake
It is higher to filter efficiency；Light transmittance percent change is big, and filter capacity is bigger.
(7) the maximum filter aid proportion of selection light transmittance percent change；When light transmittance percent change maximum, filtering
Time but longest when, select light transmittance percent change take second place filter aid proportion.
Remarkable advantage of the invention is: the method for the present invention step is simple and easy, effectively can quickly determine that filter aid is matched
Than determining that filter aid proportion has important guiding effect to actual production.
Specific embodiment
Further to disclose rather than the present invention is limited, the present invention is described in further detail below in conjunction with example.
Embodiment 1
(1) different filter aid (aluminium slag fine powder, broken grass stalk, oxidation trough micro mist) and content range, root design experiment scheme: are selected
