Question: Why are good FRP daylighting panels brittle? Will it affect the use of daylighting panels?


answer:


1. In addition to using high-quality UV resistant film and high-quality resin, the production curing degree of good daylighting panels is also an important factor. After testing, the curing degree of Ampelite daylighting panels is above 95%; The internal molecular structure is an approximately uniform network structure, which is very stable and difficult to be greatly affected by external factors such as ultraviolet radiation, water vapor, and acidic and alkaline substances. After the curing degree of the daylighting board increases, its hardness and mechanical strength (tensile strength, bending strength, etc.) will also increase, while exhibiting relatively brittleness.


2. As a building material, daylighting panels first have a certain degree of stiffness and bending strength to ensure minimal deformation under external forces. This can avoid the situation where the waterproof treatment of the sealant fails due to external forces, effectively preventing water leakage.


3. Many domestic daylighting panels add a plasticizer (i.e. softener) to increase their toughness. This substance does not participate in curing and can make the daylighting board have good flexibility, but its strength will be greatly affected. After a period of time, the substance will precipitate from the surface of the skylight panel. As a highly carcinogenic substance, it has been strictly prohibited in foreign countries, especially in EU countries. Moreover, after adding plasticizers, the aging resistance and lifespan of the daylighting board will be greatly reduced, which is equivalent to drinking poison to quench thirst. Ampelite refuses to add this substance out of a responsible attitude towards customers.


4. As a steel structural accessory, the daylighting board is strictly prohibited from being stepped on. The transportation, hoisting, and normal bending deformation of the skylight panel on the roof will not cause damage to it. Our company has provided corresponding explanations for this.


Overall, the brittleness of the daylighting board is a manifestation of its excellent comprehensive performance. As long as there are no large cracks during normal operation, it will not have any impact on its normal use. Please feel free to use it.
