Fiberglass mesh means a net made of glass fibers, which has been used for many years in different industries. Fibers or glass fibers do not have special technical characteristics; But if they are used with a series of additives, they can acquire good physical and chemical resistance. Alkali-resistant fiberglass mesh is a special type of glass fiber applications that can be very useful for various industries. In this article, we want to point out the most important features of construction fiberglass mesh.
1. Use of type E glass fibers in mesh production
Unidirectional glass fiber is one of the most widely used industrial materials known to date. The mechanical properties of this product are equal to fibers such as carbon fibers and polymer fibers. Due to the high resistance and low weight of unidirectional glass fibers, they are used in many polymer products as a reinforcing agent to obtain a very durable and light product. Another application of glass fiber is in strengthening buildings and industrial structures, such as pipes and tanks. All kinds of unidirectional glass fiber have good compatibility with all kinds of adhesives and chemical resins, including FRP epoxy resin, polyester resin and vinyl ester resin, and with the help of these resins and epoxy adhesives, they are easily attached to any surface.
2. The ability to resist alkaline environments
The most important indicator of fiberglass mesh is resistance to alkali substances. Mesh alkali resistance is its ability to maintain tensile strength properties in an alkaline environment. The fact is that plaster mixtures and mortars made of cement have an aggressive alkaline environment with a pH factor > 11. In such an environment, the tensile strength of the network decreases. This indicator should normally be at least 30 N/mm in the direction of the warp thread and within 40 N/mm in the direction of the weft thread.
3. High strength and resistance of fiberglass mesh
One of the features of fiberglass mesh construction is its high strength and resistance. There are two tests to find out this feature:
a. Fiberglass bending resistance test
The mesh should be very tight. Because it must maintain the alkaline pH in the drying plaster. The easiest way to test the strength of the fiberglass mesh is to bend it several times in the same place along the twisted threads. If it starts to crumble or break, it is not strong enough. Also, try to crush it with a sharp movement and check the result.
b. Fiberglass brittleness test
Cover a small part of the wall with fiberglass mesh and a top layer and wait for the mixture to set completely, after it sets, hit the surface with a hammer or other tool. If you witnessed cracking and collapse of the plaster layer and fiberglass mesh, the used fiberglass mesh is not of good quality and should be replaced.
4. Light weight of fiberglass
The light weight of fiberglass is easy to understand. The unit weight of fiberglass mesh is 60 to 200 grams per square meter. One of the most appropriate solutions and the final solution to determine the quality of fiberglass mesh is to consult and get guidance from experts and consultants in the field of building retrofitting. You can consult with us about the ideal weight for each fiberglass mesh spring.
5. Variation in spring and weight distances
See the variety of springs and weights of Sorin Baft fiberglass netting. It is also mentioned here that Surin Baft laces are offered in the following sizes and weights:
- Net 65 grams, 1 meter wide
- Net 65 grams, 2 meters wide
- Net 65 grams, width 50 cm
- Net 75 grams, 1 meter wide
- Net 75 grams, width 2 meters
- Net 75 grams, width 50 cm
6. Ease of use
If fiberglass mesh is used as the bottom layer, Zylon fiber mesh is placed on the surface and the desired insulation is applied on it. And if they want to use it as a middle layer, first the first layer of insulation is applied, and after the initial adhesion and before drying, just when it is still sticking to the surface, the Zylon fiber mesh is placed on the surface and the second layer is applied. they do.
7. High economic efficiency
The use of construction fiberglass mesh has a high economic justification. You can compare the cost of using other strengthening methods with the cost of using fiberglass mesh.
8. Suitable for all kinds of architectural elements with different shapes and dimensions
Due to the fact that fiberglass mesh can be cut, you can use it in any shape and size.
9. High flexibility
Despite the high tensile strength, these fibers also have high flexibility.
10. It has acceptable adhesion in various uses
Construction fiber mesh will stick to it until the end of the structure’s life, and their life will be longer than the life of the structure. For example, to strengthen the stone, these fibers stick to the stone when the glue is semi-dry.
