Introduction

The construction industry is very important in the process of urbanization. However, the quality of buildings is not only related to their service life, but also directly affects people’s quality of life and safety. Among the many factors that affect the quality of buildings, waterproofing is particularly prominent. As a key component of building safety, waterproof materials play an irreplaceable role in ensuring the functionality of buildings and extending their service life. In recent years, with the advancement of new material technology, more and more high-performance waterproof materials have been developed. Among them, glass fiber (referred to as glass fiber) as a new type of waterproof material has attracted much attention due to its unique properties. The application of fiberglass products has shown great potential in the field of waterproofing with their excellent mechanical strength, chemical stability and aging resistance.

Characteristics and advantages of glass fiber products

Fiberglass Product Classification

Glass fiber (abbreviated as fiberglass) is an extremely fine fiber formed by melting silicate through high-speed rotation or drawing process. It has the characteristics of light weight, high strength, corrosion resistance and good insulation. According to different production processes, raw materials and uses, fiberglass products can be divided into the following categories:

Roving Glass：
fiber rovings have good insulation material and can be used in applications that require electrical isolation. They can withstand high temperatures without deformation or degradation, which makes it suitable for environments that require heat resistance. Due to their chemical composition, they have strong resistance to most chemicals and are not easily corroded.
Although glass fiber rovings are very thin, they have high strength resistence, which means that it can withstand large tensile forces without breaking.
Glass fiber rovings have a low density and are therefore light, which is very important for applications that need to reduce weight (such as aviation and automotive industries).
Glass fiber rovings are resistant to deformation, that is, they are not easy to permanently deform when subjected to load.

Chopped strands：
Chopped strands can be used as reinforcing materials in composite materials to improve the mechanical properties of products, such as tensile strength and flexural strength.
Due to their short length, they are easily evenly distributed in the matrix material, thus avoiding the agglomeration phenomenon that may occur in long fibers.
Compared with long fibers, chopped strands are easier to process and can be processed using a variety of molding processes, such as injection molding and compression molding.

Fiberglass Mats:
Fiberglass Mats have good thermal insulation performance and can effectively prevent heat transfer. They are suitable for thermal insulation of building walls, roofs, pipes, etc.
Due to their porous structure, fiberglass mats can absorb sound wave energy and reduce noise transmission. TThey are suitable for making sound-absorbing panels, soundproof walls, etc.
Fiberglass Mats have good acid and alkali resistance and are not easily corroded by chemicals. They are suitable for the protective layer of chemical equipment.

Glass fiber cloth:
Glass fiber cloth has excellent heat resistance, can remain stable in high temperature environment, and is not easy to deform or melt.
Glass fiber cloth has good resistance to most chemicals and is not easily corroded. It is suitable for protective materials in the chemical industry.
Glass fiber cloth is a good insulating material and can be used as the insulating layer of electrical equipment.
Glass fiber cloth has high tensile strength and is not easy to break even under high stress.
Glass fiber cloth can be cut, sewn, bonded and processed as needed to make products of various shapes and sizes.

Introduction to the production process of glass fiber products

Wire drawing process:
Principle: The molten glass is squeezed out through a porous plate (leakage plate), and then stretched into filaments by a high-speed rotating roller.
Features: High production efficiency, continuous production, uniform fiber diameter, stable and reliable quality.
Application: Suitable for the production of continuous glass fiber roving, mesh cloth and other products.
Spraying up process:
Principle: The molten glass is sprayed into fibers through high-pressure air or steam, and then collected.
Features: The fiber length is short, suitable for the manufacture of chopped yarn, bulk fiber, etc.
Application: Suitable for the production of non-woven fabrics, spray-molded composite materials, etc.

Specific application of glass fiber products in the field of waterproofing

Roof waterproofing system

Glass fiber reinforced waterproofing membrane: This type of material is usually made of glass fiber mesh cloth and modified asphalt or other polymer base materials. The glass fiber mesh cloth enhances the tensile strength of the waterproofing membrane, making the material more durable; the modified asphalt or polymer gives the material good flexibility and adhesion. It is suitable for waterproofing of new buildings and renovation of old buildings, especially those roofs that need to bear heavy loads or have the risk of cracks.

Underground structure waterproofing

Fiberglass mesh can be used as part of the waterproof layer to enhance the tensile strength and stability of waterproof materials. It is usually used together with organic waterproof coatings such as polyurethane and epoxy resin to form a solid waterproof barrier. It improves the crack resistance of the waterproof coating and effectively prevents the formation of cracks caused by foundation settlement and other reasons.

Waterproofing in special environments

In some special environments, such as bridges and tunnels, waterproofing is not only related to the safety of buildings, but may also affect the normal operation of transportation systems. The application of glass fiber materials in these special environments has the following characteristics：

Bridge waterproofing:
Bridges are often in environments with large temperature differences and high humidity, and are easily affected by vehicle vibration. Glass fiber reinforced composite materials are used as bridge deck waterproofing layers, taking advantage of their high elasticity and weather resistance to meet the above challenges. Usually, spraying or rolling is used for construction to ensure that the waterproof layer is evenly distributed and tightly bonded to the bridge deck.
Tunnel waterproofing:
The internal environment of the tunnel is closed, the construction space is limited, and there is a risk of groundwater infiltration. Use glass fiber reinforced waterproof sheets and waterproof coatings to form multiple waterproof protections. Fix the waterproof sheet on the inner wall of the tunnel, pay attention to the sealing treatment of the joints, and ensure the integrity of the entire waterproof system.

In Conclusion

Fiberglass materials have high tensile strength and can effectively enhance the structural stability of the waterproof layer and prevent damage caused by external forces. Glass fiber is not corroded by most chemicals and is suitable for a variety of environmental conditions, which prolongs the service life of waterproof materials. Whether in extreme high or low temperature conditions, glass fiber can maintain stable performance, is not easy to age, and is suitable for applications in various climate environments. At the same time, glass fiber can be used in combination with a variety of substrates, such as asphalt, polymers, etc., to form composite materials with different properties to meet diverse waterproofing needs.
