Description

Technical Field

[0001] The invention relates to the technical field of corrosion resistance testing of fabrics, and in particular to a corrosion resistance testing device for fabric production. Background Art

[0002] With the development of textile manufacturing industry, a large number of fabrics have corrosion resistance. In the actual fabric production process, it is necessary to inspect the fabrics to determine whether their corrosion resistance meets the standard. It is usually necessary to soak them in corrosive solutions of different concentrations, and then take out the fabrics for inspection one by one. The corroded fabrics usually use a microscope to observe the corrosion changes of the yarn. The current corrosion resistance test device for fabric production mainly takes samples after soaking in the corrosive solution and places them under a microscope for observation. It is not convenient to observe the degree of corrosion directly under the microscope. It is cumbersome to manually take and replace samples, and it is not convenient to quickly switch different samples. At the same time, a large amount of corrosive liquid is attached to the fabric, which is not convenient to remove and then observe and test. It is also easy to corrode the microscope and is not convenient for automatic dilution protection after the test is completed. The volatilization of corrosive solutions is more harmful and causes damage to the respiratory system of the staff. In the actual operation process, it is also easy to splash and burn the staff. During the fabric test observation process, it is not convenient to move the yarn to observe the corrosion of the inner layer of the fabric, and the corrosion resistance test structure is not comprehensive enough.

The structure is compact and can be used directly under a microscope, and the upper fill light 2013 and the bottom fill light 403 are used to fully fill the light to ensure clear microscopic observation. Different concentrations of corrosion liquid are added to a circle of corrosion adding holes 2011 respectively. Acidic or alkaline solutions can be used according to needs. The observation hole 2012 is aligned with the microscope lens. After a long period of corrosion, when it is necessary to observe the effect of the sample after the corrosion test, the upper flange ring 101 can be rotated.

[0042] In the disclosed embodiment, the corrosion liquid leakage prevention component 5 includes: a cover buckle plate 501, an adsorption iron ring 5011, a rubber plug 502, a plug-in shaft 503, a closed tension spring 504 and an electromagnet 505. The cover buckle plate 501 is fixedly installed on the corrosion addition hole 2011; the cover buckle plate 501 is fixedly sleeved with an adsorption iron ring 5011; the cover buckle plate 501 is embedded with a rubber plug 502, and the rubber plug 502 is used to insert a syringe to introduce the corrosion liquid; the adsorption iron ring 5011 is slidably sleeved with a plug-in shaft 503, and the bottom of the plug-in shaft 503 is an inclined structure; the closed tension spring 504 is sleeved on the plug-in shaft 503; the end of the closed tension spring 504 is fixedly installed at the bottom of the cover buckle plate 501, and the other end of the closed tension spring 504 is connected to the plug-in shaft 503; an electromagnet 505 is fixedly installed on the top of the plug-in shaft 503, and the electromagnet 505 is used for magnetically attracting the iron ring 5011; the leakage prevention control component 6 includes: an electrical installation block 601, an electrical spring 602 and an electrical sheet 603, and the electrical installation block 601 is fixedly installed on the side of the corrosive liquid tray 201; an electrical spring 602 is fixedly installed at the bottom of the electrical installation block 601, and the electrical spring 602 is an elastic conductor; an electrical sheet 603 is fixedly installed at the bottom of the electrical installation block 601, and the electrical sheet 603 is aligned with the end of the electrical spring 602; the electrical spring 602 is attached to the arc-shaped notch opened on the electrical control ring 1011; the electrical spring 602, the electrical sheet 603 and the electromagnet 505 are connected in series with a power supply; the isolation component 7 includes : Isolation plate 701 and cloth fitting pad 702, isolation plate 701 is fixedly installed on the inner side of corrosion adding hole 2011; cloth fitting pad 702 is fixedly installed on the bottom of isolation plate 701, and cloth fitting pad 702 is a soft rubber structure; there is an inclined hole on isolation plate 701; the inclined hole in the middle of isolation plate 701 is aligned with plug-in shaft 503, and isolation plate 701 is used in conjunction with plug-in shaft 503, so that when it is necessary to rotate the cloth to switch the test observation sample, the corrosion liquid supply can be automatically closed, the concentration accuracy of the corrosion liquid in each area of ​​the cloth can be improved, and the corrosion areas under different corrosion adding holes 2011 can be prevented from mixing when the cloth is rotated, so as to ensure that the corrosion concentration of the cloth under a circle of corrosion adding holes 2011 is increasing one by one. When the cloth is manually rotated to switch the observation position, the plug-in shaft 503 is automatically controlled to move down to close the isolation plate 701 to prevent manual forgetting and ensure the quality of corrosion test. When the upper flange ring 101 is rotated to switch the cloth observation position, the arc-shaped notch on the power-connecting control ring 1011 is driven to squeeze the power-connecting spring 602 to elastically move up to fit the power-connecting sheet 603. At this time, a circle of electromagnets 505 is connected, and the iron ring 5011 is magnetically attracted, which drives the plug-in shaft 503 to press down and fit the isolation plate 701. The end of the plug-in shaft 503 will also be inserted into the cloth fitting pad 702, so that the corrosive liquid in each corrosion adding hole 2011 is isolated, and the rotating cloth will not be further corroded by the corrosive liquid.

[0043] Embodiment 2, on the basis of embodiment 1, the dilution protection member 8 comprises: a water storage tank 801, a drainage cylinder 8011 and a closing cover 802, the water storage tank 801 is fixedly mounted on the corrosive liquid tray 201; the closing cover 802 is threadedly connected to the water storage tank 801; a drainage cylinder 8011 is fixedly mounted on the bottom of the water storage tank 801, and a circle of through holes is provided on the outer side of the drainage cylinder 8011; the dilution protection member 8 also comprises: an extrusion sealing plug 803 and a drainage tension spring 804, an extrusion sealing plug 803 is slidably sleeved in the drainage cylinder 8011 at the bottom of the water storage tank 801 The sealing plug 803 is provided with an inclined surface in the middle of the extruded sealing plug 803; the inclined surface in the middle of the extruded sealing plug 803 is used to discharge the dilution water; a drainage tension spring 804 is sleeved on the extruded sealing plug 803, and the end of the drainage tension spring 804 is connected to the top of the drainage cylinder 8011, and the other end of the drainage tension spring 804 is connected to the extruded sealing plug 803; the bottom of the extruded sealing plug 803 elastically squeezes the bottom sealing disk 401, and the dilution protection part 8 can be used to automatically dilute the surface when the staff removes the cloth after the corrosion resistance test of the cloth is completed. The surface is used to prevent the corrosive liquid concentration on the surface of the cloth from being too high. When the cloth is removed, the corrosive liquid on the surface of the cloth causes damage to the staff. It is safer to use, especially for some cloths with good hydrophobic properties. After the cloth is removed, the high concentration of corrosive liquid on its surface is easy to cause burn accidents once it touches the staff. The dilution protection part 8 is automatically controlled to avoid the traditional cloth samples usually needing manual dilution and discarding after the test is completed. Otherwise, it is easy to cause corrosion to the waste plastic bag and other hidden dangers. When the lower flange ring 103 and the upper flange ring 101 are separated, once the extrusion sealing plug 803 is no longer squeezed by the sealing disk 401, under the pull of the drainage tension spring 804, the extrusion sealing plug 803 is quickly pressed down, and the drainage tube 8011 is no longer blocked to achieve drainage, so as to dilute the corrosive solution on the cloth, further increase the safety of the discarded cloth samples, and prevent the staff from being burned by the cloth samples. It is more suitable for corrosion tests with higher concentrations. This structure is cleaned after use to prevent some corrosive solutions attached to the surface from causing damage to the staff.

[0044] The working principle of this embodiment is as follows: first, place the fabric between the lower flange ring 103 and the upper flange ring 101, tighten a circle of flange bolts 102 to fix the fabric, place the support leg 202 on the microscope stage, then rotate the positioning bolt 203 to thread the bottom of the bottom sealing disk 401 for positioning, and press and clamp it with the clamp of the microscope, add different concentrations of corrosive liquid to the circle of corrosion adding holes 2011, insert a syringe through the rubber stopper 502 to introduce or extract the corrosive liquid, align the observation hole 2012 with the microscope lens, and after a long period of corrosion, when it is necessary to observe the effect of the sample after the corrosion test, rotate the upper flange ring 101, and the fabric is driven to rotate, and the corrosion area below the circle of corrosion adding holes 2011 is brought The cloth can be observed by aligning the observation hole 2012 in sequence; the wire-pulling shaft 302 is rotated to descend in height so that the conical structure at its end is fitted on the surface of the cloth. As the cloth is rotated, the end of the wire-pulling shaft 302 will squeeze between the textile yarns of the cloth, play the role of spacing the yarns and shifting them outwards. At this time, it can be observed under a microscope. For the convenience of observation, after the wire-pulling shaft 302 is inserted into the yarns and shifted, the wire-pulling shaft 302 can be rotated to rise without blocking the position of the shifted yarns; the bottom sealing disk 401 is positioned by the positioning bolt 203 to ensure that the bottom fill light 403 is always aligned with the observation hole 2012 for fill light. During the test of rotating the cloth, the suction pump external to the suction pipe 404 continuously pumps air pressure to absorb the corrosive liquid remaining on the cloth;

[0045] When the upper flange ring 101 is rotated to switch the cloth observation position, the power control ring 1011 is driven to rotate at the same time, and the arc-shaped notch on the power control ring 1011 will squeeze the power spring 602. After the power spring 602 is pressed, it moves up to fit the power sheet 603. At this time, a circle of electromagnets 505 is connected, and the iron ring 5011 is magnetically attracted, which drives the plug-in shaft 503 to press down and fit the isolation plate 701. The end of the plug-in shaft 503 will also be inserted into the cloth fitting pad 702, so that the corrosive liquid in each corrosion addition hole 2011 is isolated. At this time, the rotating cloth will not be further corroded by the corrosive liquid. After the detection is completed, the upper flange ring 101 is rotated to reset, that is, the power control ring 1011 is driven to align with the power spring 602 again. At this time, the end of the power spring 602 is elastically reset downward, and a circle of electromagnets 505 is disconnected, and the iron ring 5011 is no longer magnetically attracted. Under the pull of the closed tension spring 504, the reset and upward movement can be achieved. At this time, the inclined hole of the isolation plate 701 is no longer blocked, and the corresponding circle of corrosion addition holes 2011 again performs corrosion test on the corresponding fabric below; unscrew the closing cover 802 in advance to introduce pure water into the water storage tank 801. When the fabric needs to be removed, remove the present structure from the microscope, and the staff wears protective gloves to operate, rotate and remove a circle of flange bolts 102 and positioning bolts 203, and then separate the lower flange ring 103 from the upper flange ring 101. When separating the lower flange ring 103 from the upper flange ring 101, once the extrusion closing plug 803 is no longer subject to the limiting extrusion of the sealing disk 401, under the pull of the drainage tension spring 804, the extrusion closing plug 803 is quickly pressed down and no longer blocks the drainage tube 8011. Drainage can be achieved between the circle of through holes in the drainage tube 8011 and the inclined structure in the middle of the extrusion closing plug 803 to dilute the corrosive solution on the fabric.
