Why does the glass rod have a yellowing phenomenon?

glass rod is mostly used for internal and external wall insulation. It has the effect of heat preservation, heat insulation and energy saving, and is crack-proof. It can be used in conjunction with plastering mortar on the wall to prevent cracking. It can also be used in marble back stickers, mosaics, Roman columns, extruded boards and other places.

When purchasing glass rod, most people are most concerned about the quality issue. Generally, they evaluate and judge from the following aspects: tensile strength, glass rod shaping, whether the Fiber Glass is uniform, surface color and other aspects.
The tensile strength is generally 1540N before leaving the factory. The Fiber Glass size is generally 2.5mm×2.5mm, 3mm×3mm, 4mm×4mm, 5mm×5mm, 6mm×6mm and other common Fiber Glass specifications. Whether the Fiber Glass is uniform depends on whether the warp and weft are straight. The use of large-scale weaving will have this advantage, with uniform Fiber Glass and uniform warp and weft. The shaping of glass rod is a problem that customers are most concerned about. Proper shaping is related to the difficulty of construction. According to the actual construction situation, customers will propose the degree of hardness and softness they need.
Many emerging enterprises do not master the temperature in the furnace when baking cloth. The temperature is too high, which causes the glass rod to become hard as a whole, turn yellow, and look very ugly. Some inexperienced new workers also have technical deficiencies, which causes the glass rod to be baked too hard and turn yellow. This is a loss for both customers and manufacturers. Therefore, our company strictly controls the quality in production and resolutely does not allow unqualified products to be sold, fundamentally guaranteeing the quality of our construction.
There is also a later work about glass rod, which is the packaging problem. If the packaging work is not done well, it will directly affect the quality of the glass rod after it arrives at the destination. The subversion during transportation will seriously affect the shaping of the glass rod, so we use plastic sealing and tight packaging, and transport it in cartons or pallets to avoid subversion and damage to the shaping of the glass rod.
