Abstract
The invention discloses a detection method for a coating volume ratio. The detection method comprises the following steps: (1) fetching one piece of clean aluminum sheet; (2) weighing the aluminum sheet in air and marking the weight as W1; putting the aluminum sheet into water, weighing by using a lifting hook and marking the weight as W2; (3) coating the aluminum sheet with coating by a coil bar and putting the aluminum sheet coated with the coating into a drying oven to be dried; (4) cooling the aluminum sheet in the air, weighing the aluminum sheet and marking the weight as W3; putting the aluminum sheet coated with the coating into the water, weighing by using the lifting hook and marking the weight as W4; and (5) calculating according to following formulas: the dry film specific gravity=(W3-W1)/[(W3-W4)-(W1-W2)] and the volume solid=D/the dry film specific gravity*NV%, wherein the D is a wet film specific gravity and the NV% is the weight solid of the coating. According to the method, the volume solid of the coating can be simply and rapidly detected and the method has the operability in laboratories of middle and small-sized enterprises; the detection errors are relatively small.
Description
Technical field
The present invention relates to technical field of coatings, especially relate to a kind of detection method of coating volume ratio.
Background technology
At present in liquid coating, the volumetric determination of non-volatile content is that measuring method based on national standard is measured, and this measuring method is comparatively complicated, and formality is loaded down with trivial details, and in large-scale coating Yuan He coating producer, as research, the method is comparatively rational.
But as Coil Coating Products producer in actual operating process, it is particularly complicated that the method seems, and be not professional coating experiment personnel, detects error larger, the data obtained reference value is little.
Summary of the invention
Not enough for prior art, technical matters to be solved by this invention is to provide a kind of detection method of coating volume ratio, to reach, detects object easy and simple to handle.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
The detection method of this coating volume ratio, described detection method comprises the following steps:
(1) get one of clean aluminium flake;
(2) aluminium flake is weighed and is designated as W1 in air, then aluminium flake is inserted in water to suspension hook and weigh and be designated as W2;
(3) with line rod, coating is applied on aluminium flake, the aluminium flake that scribbles coating is inserted to drying in oven;
(4) after cooling in air, weigh and be designated as W3, then the aluminium flake that scribbles coating is inserted in water to suspension hook and weigh and be designated as W4;
(5) calculate as follows: dry film proportion=(W3-W1)/[(W3-W4)-(W1-W2)], volume solid part=D/ dry film proportion * NV%, wherein, weight solid part of D-wet film proportion, NV%-coating.
Wherein, in described step (1), with butanone, clean aluminium flake.
In described step (2) and step (4), insert in water and weigh, on aluminium flake surface and the water surface, do not have the water section that enters of the suspension hook of contactless between the utensil of foaming, aluminium flake and placement water, aluminium flake to remove the peel zero clearing.
In described step (3), line rod is wiped clean by butanone.
In described step (3), on the surface of aluminium flake, there is no bubble.
The present invention compared with prior art, have the following advantages: fixing part of volume that the method can detect coating is quickly and easily coating volume ratio, in the laboratory of medium-sized and small enterprises, has operability, and detection time is short, be convenient to detect operation, detect error relatively little.
Embodiment
Description below by embodiment, is described in further detail the specific embodiment of the present invention.
The detection method of this coating volume ratio, comprises following concrete operation step:
(1) get one of clean aluminium flake, the specification of aluminium flake is thick 0.5mm * long 9mm * wide 6mm, with butanone, cleans aluminium flake;
(2) aluminium flake is weighed and is designated as W1 in air, aluminium flake being inserted in water to suspension hook weighs and is designated as W2 again, while wherein, weighing in water, first confirm: 1. on aluminium flake surface and the water surface, do not have to bubble, 2. between the utensil of aluminium flake and placement water, the water section that enters of suspension hook contactless, 3. aluminium flake has been removed the peel zero clearing;
(3) with butanone, 20# line rod is wiped clean, with 20# line rod spreader, coating is applied on aluminium flake again, the aluminium flake that scribbles coating is inserted to drying in oven to be solidified, baking oven is air blast constant temperature oven, baking temperature is 250 ℃, taking-up is cooling in air, and what wherein will confirm is, 1. on the surface of aluminium flake, do not have bubble, 2. must not soak cooling;
(4) after cooling in air, weigh and be designated as W3, the aluminium flake that scribbles coating being inserted in water to suspension hook weighs and is designated as W4 again, while wherein, weighing in water, first confirm: 1. on aluminium flake surface and the water surface, do not have to bubble, 2. between the utensil of aluminium flake and placement water, the water section that enters of suspension hook contactless, 3. aluminium flake has been removed the peel zero clearing;
(5) calculate as follows:
Dry film proportion=(W3-W1)/[(W3-W4)-(W1-W2)];
Volume solid part=D/ dry film proportion * NV%;
Coating rate=NV%*10/ dry film proportion;
Wherein,
W1-aluminium flake is weight in air;
W2-aluminium flake is weight in water;
W3-aluminium flake+dry-coated material weight in air;
W4-aluminium flake+dry-coated material weight in water;
D-wet film proportion, wet film proportion is the proportion of coating, and the manufacturer of coating provides, and also can utilize wet film picnometer directly to measure, and concrete measuring method is referring to GB/T1756, coating gravity test method;
Weight solid part of NV%-coating, weight solid part of coating is the solids content of coating, and the manufacturer of coating provides, and also can measure, and concrete measuring method is referring to GB/T1725, the assay method of solids coatings.
The method can detect fixing part of volume of coating quickly and easily, in the laboratory of medium-sized and small enterprises, has operability, detects error relatively little.
Obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present invention and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
