Abstract
A kind of coating sample salt spray test protective device belongs to the corrosion-resistant evaluation field of inorganic/organic coating.Including fastening bolt (1), backboard (2), sample (3), washer (4), sample box (5)；Washer (4) and sample (3) are put into sample box (5), backboard (2) insertion card slot (6), with fastening bolt (1) that sample (3) and washer (4) is fixed.The advantage is that simple processing, swift to operate, effectively solve the problems, such as that organic coating sample edge and the back side is not disposable, for carrying out the salt spray test of inorganic/organic coating metal making sheet.
Description
Technical field
The utility model belongs to inorganic/organic coating corrosion evaluation technical field, more particularly to a kind of coating sample salt fog
Test protective device.Salt spray test is carried out after being coated on the metal material suitable for coating in the process to the non-Experimental Area of sample
Isolated.
Background technology
The life assessment of coating is mainly carried out using neutral salt spray test, and evaluation method is that coating is coated on certain size
Metal test plate (panel) on, after being then placed in the corrosion that certain time is carried out in salt fog cabinet, the pattern variation of evaluation test zone-coating.
And the salt spray resistance of coating is significantly larger than the metals test plate (panel) such as common tinplate, therefore for the property of effectively evaluating coating
Can, it generally requires entirely to coat test plate (panel) with coating, so results in coating sample long preparation period, it is complicated for operation.And metal
Often than sharp, sharp edge is totally unfavorable for the cladding of coating at the edge of test plate (panel), often results in coating sample from side
Portion destroys, and influences test accuracy or even causes test failure.
Therefore, it is necessary to design a kind of device that can protect sample edge and back, reaching identical sealing effect
Sample preparation efficiency can be improved simultaneously.The improvement of the device is for improving the sample preparation efficiency of coating sample, improving the accuracy of experiment
All it is of great significance.
The content of the invention
The purpose of this utility model is to provide a kind of coating sample salt spray test protective devices, solve conventional application examination
The problem of sample fabrication cycle is long, and edge covered effect is poor.A closed cavity is formed using device, by the non-test area of sample
Domain isolates with experimental enviroment, but can guarantee test area and experimental enviroment effective interception and effective area accuracy.
The utility model includes fastening bolt 1, backboard 2, sample 3, washer 4, sample box 5.Washer 4 and sample 3 are put into examination
In sample box 5, backboard 2 is inserted into from card slot 6, is fixed sample 3 and washer 4 with fastening bolt 1.
Fastening bolt 1, sample box 5 and backboard 2 are made of nylon or polytetrafluoroethylene (PTFE)；
Washer 4 is made of rubber.
The utility model has the advantage of：The device makes simple, easy to operate, the cavity guarantor formed using device
Non-test zone isolation experimental enviroment is protected, substitutes conventional specially treated coating edge sealing or paraffin edge sealing, for carrying out coating
Salt fog evaluation experimental.
The effect of sample box is that sample can be accommodated by providing a cavity, and provides a fixed-size window
Mouth can expose the test zone of sample.The effect of washer be part outside the test zone by sample and experimental enviroment every
From, backboard isolating for the sample back side and experimental enviroment.Sample box and backboard are made of polytetrafluoroethylene (PTFE), provide intensity
There is preferable corrosion resistance simultaneously；Washer is made of rubber, has certain elasticity, can be effectively to sample after compression
It is sealed.
Description of the drawings
Fig. 1 is the assembling schematic diagram of the utility model：Wherein, fastening bolt 1, backboard 2, sample 3, washer 4, sample box 5.
Fig. 2 is sample box schematic top plan view.
Fig. 3 is sample box left view schematic diagram.Wherein, card slot 6, sample exposed region 7.
Fig. 4 is backboard schematic diagram.Wherein, fastening bolt holes 8.
Specific embodiment
Fig. 1-4 is specific embodiment of the present utility model.
The utility model includes fastening bolt 1, backboard 2, sample 3, washer 4, sample box 5.Sample box 5 is for offer one
The cavity of sample can be accommodated, and be provided with card slot 6 and sample exposed region 7 on it, washer 4 be used for by non-Experimental Area with it is molten
Liquid is isolated, the sample in the range of exposed sample exposed region 7.
The whole assembling of the device is then placed in sample 3, by backboard 2 as shown in Figure 1, washer 4 is put into sample box 5
It is inserted into from card slot 6, is finally fixed sample 3 and washer 4 with fastening bolt 1.It is exposed in exposed region so as to complete the making of sample
In the range of area be test surfaces.
Wherein sample box 5, backboard 2, fastening bolt 1 are made of polytetrafluoroethylene (PTFE), and washer 4 is made of rubber, is had
Certain elasticity plays sealing function, and is convenient for changing.
It only needs to make the sample box 5 of respective area exposed region and washer 4 if you need to adjust test area.
Sample after installation is complete can be put into salt fog cabinet and carry out corrosion test.
