Abstract
The invention provides a method for detecting the surface cleanliness of aluminum, aluminum alloy plates, strips and foils, wherein vegetable oil is uniformly painted on the surface of an aluminum plate; white tissue paper is pressed by a cylinder with certain weight and contact area, the aluminum plate is wiped within specified area, and aluminum powder impurities on the aluminum plate or residual oil are absorbed by the white paper; and the surface cleanliness of the aluminum plate is indirectly judged by comparison of the color of the white paper and a standard color card. The method is simple and easy, has low cost and accurate determination result, and is suitable to be used for judging the surface cleanliness in industrialized production.
Description
Technical field
The invention belongs to aluminium and aluminium alloy technical field, more specifically relate to the detection method of a kind of aluminium and aluminum alloy strip foil surface clearness.
Background technology
In aluminium and aluminum alloy strip foil production and transport process, the reason of each side all can make the surface of aluminium and aluminum alloy strip foil contain certain aluminium powder or dirt (being mainly aluminium powder) and residual wet goods, causes aluminium and aluminum alloy strip foil surface to pollute; Pollute weight to the follow-up various certain influences that are processed with, therefore various aluminium converted products, particularly plate, band, paper tinsel all require clean surface.And all relevant criterion all have only the ocular estimate of employing to qualitatively judge at present, the method for still do not have effectively, scientific quantitative being judged aluminium and aluminum alloy strip foil surface clearness degree.
Summary of the invention
The present invention provides the semi-quantitative detection method of a kind of aluminium and aluminum alloy strip foil surface clearness.Low, simple, the easy row of this method cost, quick and easy, measurement result is accurate, is applicable to very much suitability for industrialized production.
The detection method of aluminium of the present invention and aluminum alloy strip foil surface clearness, it is characterized in that: described method is: evenly be coated with in surface of aluminum plate and spread vegetable oil, utilize right cylinder to push down white thin paper again with constant weight and contact area, in the regulation area, carry out wiping, different and the dirt oil residues of aluminium powder on the aluminium sheet is adsorbed on the blank sheet of paper, the color of contrast blank sheet of paper and standard color card is come indirect judgement aluminium material surface cleanliness by judgement blank sheet of paper gray shade scale.
Remarkable advantage of the present invention is: the test articles for use instrument that method of the present invention adopts is simple, do not need specific apparatus, simply, easily row, to detect cost low, measurement result is accurate, is applicable to very much the judgement of suitability for industrialized production aluminium and aluminium alloy plate, band, foil surface clearness.
Embodiment
(1) aluminium and aluminum alloy strip foil sample are cut along the plate width direction, make the surface area of each sample be not less than 15*15cm; Sample must not directly touch with hand;
(2) aluminium foil surface that detects at needs drips and is no more than three vegetable oil, uses the plexiglas disc gently to press oil droplet, makes oil evenly spread all over aluminium foil surface, need guarantee that disc cleans before the use glass disc, please clear up disc before and after each test;
(3) with the folding 3-4 layer of blank sheet of paper, cover on the thin paper with applicator, be placed in the pipe, place on the surface that needs test, plastic tube is moved along spacing square frame edge at test surfaces, form the pattern of certain area, thin paper and applicator are arranged in the described plastic tube, at same local counteragent, applicator is not exerted oneself in the mobile process then;
4) with white thin paper and Kodak's standard color card contrast, judge sample cleanliness grade.
