As we all know, the glass fiber reinforced plastic hydrochloric acid tank is composed of several levels, but now many people do not know much about each level. In fact, each level has its own unique characteristics and functions. Then I will introduce it in detail below.
Inner surface layer: It is a part of the inner lining layer, the resin content is above 95%, and the surface felt is enhanced, which is smooth and air-tight, and mainly plays the role of anti-corrosion and anti-leakage.
Secondary inner layer: the second part of the inner lining, the resin content is above 70%, the main content is the lining resin and chopped fiberglass fiber, which is born to protect the inner surface layer, can prevent cracks from spreading and improve the inner resistance of the inner lining Pressure failure capability.
Structural layer: It is formed by impregnating the structural layer resin with glass fiber cloth. It can withstand various compressive stresses, tensile stresses, and external loads. The wall thickness is determined according to the force of the storage tank. It has great strength and rigidity. Guarantee the stability of the entire product. The outer protective layer is the protector of the overall structure. It has been exposed to the atmosphere for a long time. In order to prevent its photooxidation and slow down aging, a professional UV absorber is added to the 100% resin content.
The above is the structural level of the FRP hydrochloric acid tank. I hope it can be helpful to everyone.
