Which fiberglass is best for gypsum board manufacturing?

Introduction

In the modern construction and decoration industry, gypsum board, as an important building material, is favored for its excellent physical properties and wide application. However, traditional gypsum materials have certain limitations in strength, durability and crack resistance. To overcome these shortcomings, glass fiber is widely used in gypsum board manufacturing as a reinforcing material. This article will explore in depth why glass fiber is so important for gypsum board, different types of glass fiber and their characteristics, their specific applications in gypsum board, how to choose the most suitable type of glass fiber for gypsum board, and introduce the high-quality gypsum yarn produced by Hebei Yuniu New Materials Technology Co., Ltd.

Why is glass fiber important for gypsum board?

Gypsum board is a common interior decoration material widely used in building structures such as walls, ceilings and partitions. Although gypsum itself has good plasticity and fire resistance, its brittleness and easy cracking characteristics limit its use in certain application scenarios. In order to improve the strength, toughness and durability of gypsum board, reinforcing materials are usually added during the production process. Glass fiber is one of the ideal reinforcing materials.

1. Improved strength and toughness

Glass fiber is evenly dispersed in the gypsum slurry to form a three-dimensional network structure, which significantly improves the overall strength and toughness of the gypsum board. This strengthening effect not only reduces the risk of damage to the gypsum board during construction and use, but also extends its service life.
2. Crack resistance

Gypsum board is prone to microcracks during the drying process, especially in environments with large temperature changes or humidity fluctuations. Glass fiber can effectively inhibit the expansion of these microcracks, thereby improving the crack resistance of the gypsum board and ensuring its long-term stability and aesthetics.

3. Durability and weather resistance

Glass fiber has excellent corrosion resistance and weather resistance, and can maintain its mechanical properties for a long time in harsh environments. This makes glass fiber an ideal choice for improving the durability of gypsum board, especially for applications in high humidity or high salinity environments.

4. Convenient construction

Glass fiber is easy to mix with gypsum slurry, and the construction process is simple, which can improve work efficiency and reduce construction costs. In addition, glass fiber can also improve the surface finish of gypsum board and reduce the workload of subsequent processing.

Glass fiber types and their characteristics

Glass fiber can be divided into many types according to different production processes and application requirements. The following are several common types of glass fiber and their characteristics:

1. Gypsum roving

Gypsum roving is to cut continuous glass fiber into small segments of a certain length and then evenly dispersed in gypsum slurry. Chopped yarn has high tensile strength and good dispersibility, which can effectively enhance the overall strength and toughness of gypsum board. Chopped yarn is usually used in the production of ordinary gypsum board and is suitable for most interior decoration and partition projects.

2. Alkali-resistant roving

Alkali-resistant roving is to add zirconium oxide and other ingredients to glass fiber to make it more alkali-resistant. This kind of glass fiber is usually used in cement-based composite materials to prevent alkaline substances from corroding the glass fiber, resulting in a decrease in its strength. Alkali-resistant yarn is relatively less used in gypsum board, but it has unique advantages in special environments (such as high alkaline environments).

3. SMC roving

SMC roving is mainly used in the production of sheet molding compound (SMC) and has high strength and good molding properties. Although SMC roving is rarely used in gypsum board, it can provide additional strength and toughness in the manufacture of some high-performance gypsum boards.

4. Fiberglass Mesh

Fiberglass is a mesh material woven from glass fibers with high tensile strength and good flexibility. Fiberglass is usually used to reinforce the surface of gypsum boards and can effectively prevent cracking and peeling on the surface of gypsum boards. Fiberglass is often used to reinforce the exterior wall insulation system and waterproof layer and is suitable for application scenarios that require additional protection.

5. Self-Adhesive Tape

Self-Adhesive Tapeis a strip material made of glass fibers with a self-adhesive layer and has good tensile strength and durability. Self-Adhesive Tape is usually used to reinforce the joints of gypsum boards and can effectively prevent cracks and peeling at the joints. Self-adhesive tape plays a key role in gypsum board construction, ensuring the integrity and aesthetics of the gypsum board.

 Application of glass fiber types in gypsum board

Different types of glass fiber have different applications in gypsum board manufacturing. Here are some specific examples:

1. Application of gypsum roving

Fiberglass gypsum roving is usually used in the production of ordinary gypsum board. It is evenly dispersed in gypsum slurry to form a three-dimensional network structure, which significantly improves the overall strength and toughness of the gypsum board. The application of gypsum yarn makes the gypsum board less likely to break during construction and use, extending its service life.

2. Application of alkali-resistant roving

Alkali-resistant yarn is mainly used for special applications in highly alkaline environments, such as gypsum board manufacturing in chemical plants and sewage treatment facilities. The tensile strength of alkali-resistant yarn is slightly lower than that of alkali-free glass fiber, but its corrosion resistance in specific environments is superior, which can effectively prevent alkaline substances from corroding glass fibers, resulting in a decrease in its strength.

3. Application of SMC roving

SMC roving is mainly used in the manufacture of high-performance gypsum board, with high strength and good molding performance. SMC yarn can provide additional strength and toughness in the manufacture of certain high-performance gypsum boards, and is suitable for occasions with high requirements for compressive strength and durability, such as high-rise buildings and public facilities.

4. Application of mesh cloth

Mesh cloth is usually used for the reinforcement of the surface of gypsum boards, which can effectively prevent cracking and peeling on the surface of gypsum boards. Mesh cloth is often used for the reinforcement of exterior wall insulation systems and waterproof layers, and is suitable for application scenarios that require additional protection. By using mesh cloth, the crack resistance and durability of gypsum boards can be significantly improved.

5. Application of self-adhesive tape

Self-adhesive tape is usually used for the reinforcement of gypsum board joints, which can effectively prevent cracks and falling off at the joints. Self-adhesive tape plays a key role in gypsum board construction, ensuring the integrity and aesthetics of gypsum boards. By using self-adhesive tape, the tensile strength and durability of gypsum board joints can be significantly improved.

Choose the best fiberglass type for gypsum board

When choosing the fiberglass type for gypsum board, the following factors need to be considered comprehensively:
