Causes of aging of general-purpose light-mining plate:
1、The action of sunlight. Adding UV absorbent to the windward surfase can absorb harmful light waves. In addition, the role of couping agent can also be taken into account, and the service life of the plate after treatment should be required in the project.
2、In the environment of high temperature and much rain, the bending strength decreases greatly due to the water entering the resin glass fiber interface.
Aging performance of general-purpose light-mining plate:
1、General purpose light-taking plate loses luster, transmittance decreases, begins to have a foggy feeling.
2、Local exfoliation, fibers are exposed. It indicated that it has suffered from serious corrosion and aging. In this case, take protective measures such as repairing or coating resin.
3、The general type light mining plate swelling, local stratification, indicating serious corrosion, has been destroyed, this situation is very dangerous. Should be based on the specific situation, determine whether repair.
