Abstract
The invention discloses a method for measuring the amount of oil applied on the surfaces of aluminum plates per unit area. The method comprises the steps that (1) at least one aluminum plate sample is taken, and the initial weight A of the aluminum plate samples is measured; (2) the oil applied on the surfaces of the aluminum plate samples is cleaned away, and the weight B of the cleaned aluminum plate samples is measured after the surfaces of the aluminum plate samples are dried; (3) the amount of the oil applied on the surfaces of the aluminum plate samples is calculated according to the formula that w=(A-B) rho h/B, wherein rho indicates the density of the aluminum plate samples, and h indicates the thickness of the aluminum plate samples. According to the method, in the process of calculating the amount of the oil applied on the surfaces of the aluminum plates per unit area, it is only needed to measure the initial weight of the aluminum plate samples and the weight of the cleaned aluminum plate samples, the shape of the aluminum plate samples is not limited, the multiple aluminum plate samples can be measured at the same time to directly obtain the average amount of the oil applied on the surfaces of the aluminum plate samples per unit area, more aluminum plate samples can be measured, measurement accuracy is higher, and the stability of measurement results is better.
Description
Technical field
The invention belongs to aluminium sheet manufacturing technology field, be specifically related to the measuring method that a kind of surface of aluminum plate unit area is coated with oil mass.
Background technology
Some aluminium sheets (as tank material processed etc.) need at its oil surface, and then need to control painting oil mass.Adopt weighing measuring method to measure the painting oil mass of surface of aluminum plate unit area in prior art, the operation steps of the method is:
(1) get oiling aluminium sheet sample to weigh, obtain its weight a;
(2) alcohol or other cleaning solvents is used the oiling of surface of aluminum plate to be cleaned up and dry;
(3) by dry after samples weighing and obtain its weight b;
(4) measure and calculate aluminium sheet area s;
(5) calculate surface of aluminum plate unit area and be coated with oil mass w:w=(a-b)/s.
Although prior art can meet request for utilization to a certain extent, still there is the problem that cannot ensure that measurement data is accurate and stable.The reason that is inaccurate and stable difference of measurement data in existing measuring method is caused to mainly contain:
(1) because needs calculate aluminium sheet area, require during sampling that aluminium sheet shape is regular, hand sampling is difficult to realize;
(2) by the accuracy limitations (survey instrument is generally the electronic balance that precision is 0.1mg) of survey instrument, sample size is restricted, causes the less measuring error of sample larger, thus needs to adopt more heavy weight measurement sample;
(3) artifical influence factor during cleaning surface of aluminum plate oiling, measurement result is unstable.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of surface of aluminum plate unit area to be coated with the measuring method of oil mass, this measuring method does not limit by the shape of aluminium sheet sample, and operating process man's activity is little, can not only measuring accuracy be improved, and multiple sample can be measured simultaneously.
For achieving the above object, the invention provides following technical scheme:
Surface of aluminum plate unit area is coated with a measuring method for oil mass, comprises the steps:
1) get at least one piece of aluminium sheet sample, measure the initial weight A of all aluminium sheet samples;
2) oiling of all aluminium sheet sample surfaces is cleaned up, after drying, measure the clean weight B of all aluminium sheet samples;
3) the surface unit area calculating aluminium sheet sample is coated with oil mass:
w= (A-B)ρh/B
Wherein, ρ is the density of aluminium sheet sample; H is the thickness of aluminium sheet sample.
Further, described step 2) in, be placed in clean container by all aluminium sheet samples, and add cleaning solvent in clean container, all aluminium sheet samples are all immersed in cleaning solvent, until the oiling of all aluminium sheet sample surfaces is all cleaned up.
Further, the soak time of described aluminium sheet sample in cleaning solvent is more than or equal to 8 minutes.
Further, when described aluminium sheet sample is immersed in cleaning solvent, stirring and washing solvent.
Further, described cleaning solvent adopts absolute ethyl alcohol or sherwood oil.
Beneficial effect of the present invention is:
Surface of aluminum plate unit area of the present invention is coated with the measuring method of oil mass, surface of aluminum plate unit area is coated with in the computation process of oil mass, only needs to measure the initial weight of aluminium sheet sample and clean weight, and need not measure the area of aluminium sheet sample again, so, the shape of aluminium sheet sample is unrestricted; In addition, due to the area of aluminium sheet sample need not be measured, therefore polylith aluminium sheet sample can be measured simultaneously, the surface unit area directly obtaining polylith aluminium sheet sample is coated with the mean value of oil mass, and need not as only can measured one piece of aluminium sheet sample in existing measuring method at every turn, aluminium sheet sample more, the precision of measurement is higher, and the stability of measurement result is also better.
