Glass fiber is widely used in corrosive environments such as chemical industry, environmental protection, and shipbuilding due to its excellent corrosion resistance. In order to achieve the best performance of glass fiber in corrosion-resistant design, it is necessary to comprehensively consider material selection, structural design, surface treatment, etc. The following is a detailed introduction to glass fiber corrosion-resistant design:

1. Core elements of glass fiber corrosion-resistant design
   Material selection:

Select glass fiber types with excellent corrosion resistance (such as ECR glass fiber, C glass fiber).

Combine corrosion-resistant resins (such as epoxy resin, vinyl ester resin) as matrix materials.

Structural design:

Design reasonable fiber arrangement and thickness to ensure that the material has sufficient strength and durability in a corrosive environment.

Avoid stress concentration points in the design to reduce the possibility of penetration of corrosive media.

Surface treatment:

Surface coating or modification of glass fiber to enhance its corrosion resistance.

Environmental adaptability:

Adjust the design plan according to the specific corrosive environment (such as acid, alkali, salt spray, etc.).

2. Key technologies for corrosion-resistant design of glass fiber
   Fiber selection:
   ECR glass fiber: has excellent acid and alkali resistance, suitable for highly corrosive environments.
   C glass fiber: has good chemical corrosion resistance, suitable for general corrosive environments.
   Resin matrix selection:
   Epoxy resin: has good corrosion resistance and strong adhesion.
   Vinyl ester resin: has excellent acid and alkali resistance, suitable for highly corrosive environments.
   Polyester resin: has low cost, suitable for general corrosive environments.
   Composite material design:
   Optimize the corrosion resistance of composite materials through a reasonable fiber-resin ratio.
   Add fillers (such as silica, silicon carbide) to further improve corrosion resistance.
   Surface coating technology:
   Use corrosion-resistant coatings (such as polytetrafluoroethylene coatings) to protect the glass fiber surface.
   Use chemical vapor deposition (CVD) or physical vapor deposition (PVD) technology for surface modification.
   Structural optimization:
   Design a multi-layer structure with the outer layer as the corrosion-resistant layer and the inner layer as the reinforcement layer.
   Avoid sharp edges and complex structures to reduce the accumulation of corrosive media.
3. Application scenarios of glass fiber corrosion-resistant design
   Chemical equipment:

Storage tanks, pipelines, reactors, etc.

Environmental protection equipment:

Sewage treatment equipment, flue gas desulfurization equipment, etc.

Shipbuilding and marine engineering:

Hull, offshore platform, submarine pipeline, etc.

Energy field:

Wind turbine blades, solar brackets, etc.

Construction field:

Corrosion-resistant building materials, waterproof layers, etc.

4. Common problems and solutions for glass fiber corrosion-resistant design
   Problem 1: Corrosive medium penetration
   Reason:

The material porosity is too high.

The surface coating is uneven.

Solution:

Optimize the composite material preparation process to reduce the porosity.

Improve the surface coating technology to ensure uniform coating.

Problem 2: Material stratification
Reason:

Insufficient interface bonding between fiber and resin.

The intrusion of corrosive media leads to interface damage.

Solution:

Use coupling agent to enhance the interface bonding between fiber and resin.

Design a multi-layer structure to block the corrosive medium.

Problem 3: Strength reduction
Reason:

Corrosion causes degradation of fiber and resin performance.

Insufficient design thickness.

Solution:

Select fibers and resins with better corrosion resistance.

Increase material thickness or reinforcement layer.
