Abstract
The invention discloses a method and a device for testing the in-situ pressure osmosis of a coating. The device consists of a pressurizing chamber which can be attached to the coating, and an air compression system which provides required atmospheric pressure for the device, wherein the pressurizing chamber is a rigid cylinder, and one end of the pressurizing chamber is open to form a coating attachment end; a water inlet and outlet valve is arranged near the coating attachment end; and a liquid level scale ruler which is used for observing the liquid level in the chamber is arranged on the pressurizing chamber. The device for testing the in-situ pressure osmosis of the coating can perform non-destructive waterproof in-situ test on the waterproof performance of the coating on the basis of not damaging the structural coating so as to directly reflect the actual condition of the waterproof performance of the coating, is particularly suitable for performing in-situ test after the coating is constructed or used for certain time, and has the advantages of convenience in operation and quick detection.
Description
Affiliated technical field
Technology of the present invention belongs to coating quality and detects, and specifically relates to coating original position pressure permeation proving installation technical field.
Background technology
The coating water-proof performance test methods generally is before construction, to test through coating sample being carried out water resistance, and coating needs to prepare in indoor laboratory separately, carry out the water resistance test then.And after coating was used to structural shielding, also not seeing had dependence test method or equipment that the water resistance of coating is detected.Coating construction environment and technology all have influence to a certain degree to the waterproof effect of coating, and have no idea to test the waterproof effect of actual coating behind coating construction back or the process certain hour.Existing geotechnological material barrier performance tester can be carried out indoor waterproof test to coating sample, detects but can't carry out outdoor structure coating water resistance; Bituminous pavement infiltration appearance is merely able to measure the infiltration coefficient of asphaltic road-mix surface course and roller-compaction bitumen mixture specimen, can not carry out on-the-spot coating original position water resistance test, can not apply or control seepage pressure.Therefore be necessary to develop a kind of method of testing and proving installation thereof simply, conveniently and efficiently, can carry out the waterproof effect of in-situ test coating in coating construction back or after using certain hour.
Summary of the invention
In view of the above deficiency of prior art, the objective of the invention is, a kind of coating original position pressure permeation proving installation is provided, and make it to have easy to operate, detect advantage fast
The objective of the invention is to realize through following means.
A kind of coating original position pressure permeation proving installation can be formed with the pressurizing chamber of coating applying with by it provides the air compression system of required air pressure by one; Said pressurizing chamber is a rigid canister, and the one of which end opening constitutes coating applying end; Said coating is provided with the Inlet and outlet water valve near fitting and holding; Pressurizing chamber is provided with the liquid level graduated scale that supplies liquid level in the observation chamber.
The present invention also aims to, obtain a kind of coating original position pressure permeation method of testing, be used for to measure the hydraulic permeability of the external skin of the buildings of accomplishing construction.
The content of said method comprises: carry out on the spot the sealing part that is determined at the buildings coating, imposes the fluid pressure of constant vertical direction in the sealing part of said coating, obtains coating original position pressure permeation performance information through the data of obtaining liquid levels.
Coating original position pressure permeation method of testing of the present invention can be carried out non-damaged waterproof in-situ test to the water resistance of coating with device on the basis of not destroying structure coating; The actual conditions of more direct reaction coating water resistance; Carry out in-situ test after being particluarly suitable for coating construction back or using certain hour, and have easy to operate, detect advantage fast.
Description of drawings is following:
Fig. 1 is the cut-open view of the embodiment of the invention;
Embodiment
Below in conjunction with accompanying drawing and practical implementation the present invention is further described.Among the figure: 1 constant-voltage equipment; 2 air compressor; 3 plastic flexible pipes; 4 tensimeters; 5 tempered glass tubes; 6-1,6-2,6-3 are standing screw; 7 top boards; 8 lower platens; 9 Inlet and outlet water valves, 10 coatings are fitted and are held.
In the present embodiment, pressurizing chamber places the lower platen 8 of its lower end to constitute by the sealing top board 7 of tempered glass tube 5, end placed on it.Lower platen 8 is the loop configuration of a hollow, and its ground is coating applying end 10.6-1,6-2,6-3 standing screw be top board 7 and lower platen 8 fixedly.
Method of application of the present invention:
A, fixing: according to coating original position pressure permeation device coating applying end 10 lower surface annulus; Draw annulus on the structural paint surface; Be coated with full adhesive in annulus inside, coating original position pressure permeation device coating fitted hold 10 to be fixed on the adhesive, guarantee all to be covered with adhesive in the slit.
B, water filling: after treating that bonding firmly, open Inlet and outlet water valve 9, water is injected in the tempered glass graduated cylinder, till the concave meniscus that injects water and 0mL scale are tangent, close the Inlet and outlet water valve.
C, measurement: according to designing requirement, open air compressor,, atmospheric pressure is controlled at testing pressure always, treat that pressure is stablized to read initial scale in the graduated cylinder after 3 minutes through constant-voltage equipment; Continue to keep pressure after 30 minutes, read scale in the graduated cylinder once more.
D, calculating: be water percolating capacity with reading for the second time scale-initial scale.
Claims (3)
1. coating original position pressure permeation method of testing; Be used for to measure to the hydraulic permeability of the external skin of the buildings of accomplishing construction; It is characterized in that; Carry out on the spot the said sealing part that is determined at the buildings coating, imposes the fluid pressure of constant vertical direction in the sealing part of said coating, obtains coating original position pressure permeation performance information through the data of obtaining liquid levels.
2. a coating original position pressure permeation proving installation is characterized in that, can be formed with the pressurizing chamber of coating applying with by it provides the air compression system of required air pressure by one; Said pressurizing chamber is a rigid canister, and the one of which end opening constitutes coating applying end; Said coating is provided with the Inlet and outlet water valve near fitting and holding; Pressurizing chamber is provided with the liquid level graduated scale that supplies liquid level in the observation chamber.
