Glass fiber mesh production process and identification

 

  1. Fabrication process of glass fiber mesh

  Reinforced fiberglass mesh is a mesh made of one-piece board. Generally, the glass fiber mesh is 59 cm wide and cannot be used by one cm. The requirements for the alkali-resistant mesh cloth of the one-piece board are very strict. The roving yarn needs to meet the national standard. Before the mesh cloth is pressed into the wet plastering glue, pre-lay the wrapping mesh and the reinforcing mesh at the door and window openings before the mesh is dry. Good, and then lay the glass fibre net from top to bottom in a large area. In order to ensure that the surface mortar is flat and does not print the net, the second plastering is carried out after the Chongqing mesh cloth reaches the strength.

  The surface decoration layer of the integrated board adopts super weather-resistant fluorocarbon coating, so it has a life of more than 25 years; due to the stability of the integrated board, if the color is changed in the future, it can be directly sprayed or replaced on the architectural decoration layer. On the outside, the composite thermal insulation board is used as the outer formwork, and the cast-in-place concrete wall and the outer formwork are poured into one, and connected by anchor bolts to make it more reliable. After the pouring is completed, the outer side is plastered with a protective layer of mortar, which meets the requirements of building energy saving of 70%.

  Exterior wall insulation board, also called horizon building exterior wall decoration integrated board, is made of polymer mortar, fibra de vidrio malla flame retardant molded polystyrene foam board (eps) or extruded board fiberglass mesh 145g is medium alkali or no It is based on alkali glass fiber woven fabric and is treated with alkali-resistant coating.

 

 

  Alkali fiberglass mesh has high strength and good alkali resistance, and plays an important structural role in the insulation system, mainly preventing the generation of cracks. Due to its excellent resistance to acid, alkali and other chemical substances and its high tensile strength in the warp and weft directions, it can evenly disperse the stress on the external wall thermal insulation system and avoid the entire thermal insulation caused by the collision and extrusion of the external impact. The deformation of the structure makes the thermal insulation layer have high impact strength, and it is easy to construct and control the quality, and it plays the role of "soft steel bar" in the thermal insulation system.

  The fiberglass mesh is based on fiberglass woven roving cloth, which is immersed and coated with a polymer alkali-resistant emulsion, so that it has good alkali resistance, flexibility and high tensile strength in the warp and weft directions. Its chemical stability is good. , high strength, light weight, good dimensional stability, strong impact resistance, plays an important structural role in building and building materials systems such as internal and external wall insulation, roof waterproofing, stone reinforcement, etc. It is composed of junction layer, thermal insulation decorative finished board, anchors, sealing materials, etc. It is not only suitable for all kinds of public buildings, but also for the external wall insulation of residential buildings; it is not only suitable for buildings in cold northern regions, but also for buildings in southern regions.

 

 

  Grid cloth is one of the prepreg glass fibre products which is mainly used in the wall. In general, its tensile strength is high. It can also be used for wall crack prevention. Today, I will share with you what is the relationship between the quality and color of this product? Let's take a closer look together.

  In our lives now, new houses generally have cracks and cracks in the walls. Especially for some wall corners, the wall joints are more intense, and this product can solve this problem very well, and a lot of fiberglass mesh tape for drywall has been used in many buildings now. , and gradually penetrated into many rural areas. Sometimes when you choose this product, you will encounter it, but there are colored products, and these colored products are of better quality than white products. So, does the quality of the product really have anything to do with the color? In fact, this is not the case. The color of this product is the pigment added to the late-stage Zainafu emulsion, which can show that the appearance of the product looks particularly beautiful and generous.

 

  However, the specifications of white and green products are the same, so the price of mesh cloth with color is generally very expensive, but the quality is the same.
