Abstract
The invention discloses leakage detection coating, which is prepared by mixing the following components in percentage by weight: 5 to 10 percent of talcpowder, 0.3 percent of industrial pigment, 0.01 to 0.07 percent of fluorescent powder and the balance of solvent water. When the coating is coated at the bottom of different boxes, the leaking parts can be detected and found conveniently through the color and fluorescence of the coating leaked out, so the detection (flaw detection) process is greatly simplified.
Description
Technical field
The present invention relates to paint field, particularly a kind of coating that is used to check seepage.
Background technology
It is casting box that existing mechanized equipment sparetime university used more, and casting box is in use because the fatigue of casting flaw and material can be split leakage.If a plurality of equipments fit together, check, judge that splitting leakage just needs the dismounting each several part or move huge casing.The particularly seepage that takes place for bottom half, even the casing of need slinging, makes and judges effort and difficulty upward by visual inspection from the bottom.
Summary of the invention
The invention provides a kind ofly fill a prescription rationally, special coating that production cost is low, this coating is coated in the bottom of different casings, can check easily by the painting color that oozes out and judge the position of splitting leakage, simplify checking process.
In order to reach above purpose, the present invention adopts following technical scheme:
A kind of inspection for leakage coating is mixed by following component in percentage by weight:
Talcum powder 5-10%;
Industry pigment 0.3%;
Phosphor powder 0.01-0.07%;
Remaining solvent water.
Be preferably:
Talcum powder 10%;
Industry pigment 0.3%;
Phosphor powder 0.06%;
Remaining solvent water.
The beneficial effect of the described technology of the application is:
Adopt this special coating to be coated in the bottom of different casings, can check easily by the painting color that oozes out and judge the position of splitting leakage, in coating, can also increase fluorescent agent in case check install below the basis and underground casing position split leakage.Use this coating, simplify the trouble-locating process of casting box greatly.
Embodiment
Below in conjunction with embodiment foregoing invention content of the present invention is described in further detail.But this should be interpreted as that the scope of the above-mentioned theme of the present invention only limits to following embodiment.Not breaking away under the above-mentioned technological thought situation of the present invention, according to ordinary skill knowledge and customary means, make various replacements and change, all should comprise within the scope of the invention.
Embodiment 1:
This kind inspection for leakage coating is mixed by following component in percentage by weight:
Talcum powder: 10%;
Green industrial pigment: 0.3%;
Phosphor powder (yellow-green colour): 0.06%;
All the other: water.
In the present embodiment, coating of the present invention is used to check the seepage of locomotive reduction box bottom.In the maintenance of diesel locomotive, main frame oiling system, static-pressure system and mechanically operated casing are arranged in the propulsion plant of car top.Each parts leaks as producing, and judges that these leakages are pretty troublesome.Machine oil can drain in the traveling portion of locomotive, and the support side bearing is arranged between traveling portion and the car body, in the side bearing casing lubricating oil is arranged, once in side bearing casing found around oil stain is arranged, can't judge that it still is the leakage of locomotive top propulsion plant that the side bearing casing splits leakage.As checking that affirmation will erect car body, could the disintegration side bearing check its bottom half, workload is big and influence the locomotive use.The paint brush that adopts above proportioning is at the side bearing bottom half, whether splits leakage by checking that the color relation of oil stain can make things convenient for, judge accurately the side bearing casing around the side bearing casing.This method is directly perceived, easy, and effect is fine judges by accident never again.
Embodiment 2:
This kind inspection for leakage coating is mixed by following component in percentage by weight:
Talcum powder: 5%;
Red industrial pigment: 0.3%;
Phosphor powder (yellow-green colour): 0.07%;
All the other: water.
C8013 is the wheel special purpose lathe, and the casting lathe bed has hydraulic pressure mounting and clamping system and the semi-underground installation of oiling system.When customary equipment inspection, there is oil stain then to be difficult to judge the position of leakage of oil in the foundation pit as finding, observing between the usage period and can only keeping, cause very big waste and pollution by replenishing machine oil.To the last just check out the oil circuit crack in the bed piece.Below lathe bed and outside the left and right sides selective headstock connection oil pipe, adopt above-mentioned coating, in routine inspection, raise the floor lid, easily check with the purple light torch light.Lathe bed just can be seen fluorescence if any splitting to leak.Use this method conveniently to check maintenance to lathe.
In sum, adopt coating of the present invention, can check easily by the painting color that oozes out and fluorescence and judge the position that casting box splits leakage, simplify (flaw detection) process of inspection greatly.
