Abstract
The invention relates to a method for detecting a coating layer thickness of waterproof coatings, which belongs to the technical field of detection methods for coating layer thickness of waterproof coatings and aims to provide a detection method for coating layer thickness of waterproof coatings which is low in cost, excellent in detection effect and simple in operation. The technical scheme of the method is as follows: a detection card is used for detecting the waterproof layer thickness, wherein the bottom edge of the detection card forms an included angle with a straight line where are the supporting leg tips of supporting legs which are connected with the detection card. The method comprises the following steps: step 1, manufacturing the detection card; step 2, holding the upper part of the detection card by a hand; inserting all the supporting legs of the detection card into waterproof layer to a basic layer; enabling the plane of the detection card to be vertical with the plane of the waterproof layer; and viewing the corresponding scale mark of the intersection between the surface of the waterproof layer and the bottom edge, wherein the reading corresponding to the scale mark is the waterproof layer thickness of a detection point; and step 3, taking out the detection card and supplementing the waterproof coatings on the detecting point. The method provided by the invention is particularly suitable for detecting the coating waterproof layer thickness being scraped and the incompletely cured coating waterproof layer thickness which is scraped just.
Description
Technical field
Water-repellent paint of the present invention is coated with the thicknesses of layers detection method, belongs to water-repellent paint and is coated with thicknesses of layers detection method technical field.
Background technology
Water-repellent paint is widely used in the waterproof of roofing, kitchen, toilet, basement etc.Polyurethane water-proof paint is to use the widest a kind of water-repellent paint at present; Waterproof coating layer design thickness is generally 1.5-2.5mm; Its construction technology is: with sleaker, brush with the even blade coating of coating on the ground of handling well, be coated with according to environment for use and performance requirement and scrape more than 2 layers or 2 layers.
Quality testing: per 100 square metres are detected a place, must not be less than three places, and required thickness adheres to specification and minimum thickness should be less than 85% of design thickness.
The quality of film waterproof material waterproof quality depends on its thickness, and the method that detects waterproofing layer thickness at present mainly contains three kinds:
(1) extracts the sample detection method.Per 100 square metres extract 20 * 20mm sample and detect with slide calliper rule.This is a kind of destructive detection method, and this detection method cost is high, check point is few, and the thickness representativeness of check point is not strong;
(2) acupuncture detection method.Pierce through water barrier and carry out sign and measure the thickness that pierces through part then with a sticker, the thickness out of true that this method records, error are big and read difficulty;
(3) supercritical ultrasonics technology detection method.Detect with supersonic thickness meter, this method measurement result has certain error, and the precision of measurement and surveying instrument quality and operating personnel's level have direct relation.Supercritical ultrasonics technology detection method complicated operation, waste time and energy and cost than higher, restricted application.
The quality of waterproof effect and water-repellent paint coating thickness have direct relation, the water-repellent paint coating thickness directly has influence on quality of waterproof layer, and mostly the water barrier seepage is because the thickness deficiency causes.The waterproof in toilet and kitchen particularly, in most cases many suites just detect a point.Present detection method is difficult in the timely coating thickness thickness defective of finding of construction stage.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, technical matters to be solved provide a kind of cost low, detect water-repellent paint effective, simple to operate and be coated with the thicknesses of layers detection method.
In order to solve the problems of the technologies described above; The technical scheme that is adopted is: water-repellent paint is coated with the thicknesses of layers detection method; Utilize a base with its on a tiptoe place straight line of the leg that the is connected test card that is angle detect waterproofing layer thickness, this method may further comprise the steps:
The first step; Make test card; The base of test card is connected with a plurality of del legs and all legs and props up tiptoe and be positioned at same straight line; It is 2 °-6 ° with the base angle that leg props up tiptoe place straight line, and the difference in height five equilibrium according to the two ends, base on the base is provided with many scale marks, and every scale mark is all represented the vertical range that tiptoe belongs to straight line of propping up of its corresponding point and leg on the base;
Second step; Hold the test card top that makes in the first step its all legs are inserted water barrier to be detected to sand-cement slurry basic unit; Keep the test card plane vertical with the water barrier plane; Check water barrier surface corresponding with the base intersection point scale mark, write down the thickness that the pairing reading of scale mark here is this check point water barrier;
In the 3rd step, take out test card, in time at check point coating water-repellent paint.
Said second step with the test card half-twist, goes on foot the thickness that described method detects a water barrier again at said check point place according to second after accomplishing, and gets the mean value of twice detected value.
A tiptoe both sides angle of said leg is 30 °-60 °.
Wherein coat the color of distinguishing the test card body on the test card of making in the said first step between two scale marks, this color region represent to detect the acceptance value scope commonly used of waterproofing layer thickness.
The beneficial effect that the present invention is compared with prior art had is: the present invention use a base with its on the leg that is connected prop up the test card that tiptoe place straight line is angle and detect waterproofing layer thickness; The leg of test card is inserted water barrier; Check water barrier plane and base intersection point; Corresponding scale mark is promptly represented the vertical range of this point and sand-cement slurry basic unit on it, and simple to operate, cost is lower; The present invention is shown as 10-30 mm scopes with the scope of vertical range 1 mm on the scale of test card, amplify 10-30 times, reads more accurate, simple.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Fig. 1 detects the structural representation of waterproofing layer thickness for using test card among the present invention.
Among the figure: 1 is test card, and 2 is leg, and 3 is the base, and 4 is scale mark, and 5 is water barrier, and 6 is sand-cement slurry basic unit, and 7 is scale mark.
Embodiment
As shown in Figure 1, water-repellent paint of the present invention is coated with the thicknesses of layers detection method, utilize a base 3 with its on a tiptoe place straight line of the leg 2 that the is connected test card 1 that is angle detect water barrier 5 thickness, this method may further comprise the steps:
The first step; Make test card 1; The base 3 of test card 1 is connected with a plurality of del legs 2 and 2 tiptoes of all legs are positioned at same straight line; 2 tiptoes of leg place straight lines are 2 °-6 ° with base 3 angles, and the difference in height five equilibrium according to 3 two ends, base on the base 3 is provided with many scale marks 4, and every scale mark 4 is all represented the vertical range that tiptoe belongs to straight line of propping up of its 3 corresponding point and leg 2 on the base;
