Glass fiber reinforced plastic water tank crack repairing technology

The invention relates to a glass fiber reinforced plastic water tank crack repairing technology. The technology comprises the following steps of polishing inner cracks of a glass fiber reinforced plastic water tank until a first-layer glass fiber cloth is exposed, respectively drilling two technique holes at two ends of the crack, cutting a metal filter screen and glass fiber cloths, uniformly coating the cracks with a prepared resin binder, pasting the first-layer glass fiber cloth, carrying out blade coating with the resin binder, pasting the second-layer glass fiber cloth, carrying out coating with the binder, simultaneously pasting the third-layer glass fiber cloth and the metal filter screen, repeating the above binder coating and pasting processes until the 4th-6th glass fiber cloths are pasted, then carrying out blade coating on the last-layer glass fiber cloth with the resin binder and carrying out curing. The technology has simple processes and a low cost, contains the stainless steel metal filter screen sandwich, improves repaired layer tensile and compressive strength and is free of water tank replacement.
