Product Description:

CORE MAT
PRODUCT DESCRIPTION
CORE MAT is a stratified reinforcing glass fiber fabric composed by 5 layers. 2 exterior layers of random mat, 1 layer of woven roving and 2 layers of synthetic fibers. The main application is for RTM and RTM Light parts where mechanical performance is a must.

CONSTRUCTION
CORE MAT has been manufactured by stitch bonding technology. The 5 layers are arranged as follows:
Layer 1: Random glass fiber mat
Layer 2: Synthetic Web
Layer 3: Woven roving
Layer 4: Synthetic Web
Layer 5: Random glass fiber mat

The layers 2 and 4 are made by a synthetic material (polypropylene)and the main purpose of these layers is to allow the resin flow and provide compressibility to the reinforcement.

STYLES
The standard materials are the ones in the following list, but other designs are also available according to customer needs

Q:What is the specification of external wall thermal insulation mesh
Mesh size: 5x5mm, 4x4mm gram weight: 80g160g / m2 Width: 1000mm2000mm length: 50m, 100m or 200m Color: White (standard), blue, green or other colors Packing: According to customer requirements 3, GRC enhanced mesh product specifications: Mesh size: 8x8mm, 10x10mm, 12x12mm gram weight: About 125g / m2 width: 600mm, 900mm, 1000mm length: 50m or 100m Color: White (standard), yellow, green or other colors Packing: According to customer requirements
Q:What is the base material of fiberglass mesh?
Of course, its base material is glass fiber. You said it was rough, probably the reason wass that in the process of producing glass fiber, immature technology caused broken filament, and after treatment, the adhesive sticker, alkali-resistant glue or weather-proof glue was unevenly attached on the surface. So it looks rough. This is just the unqualified product in production process, and there isn't any counterfeit product. These product are not beautiful and their strength will be lower than that of qualified products. (The intensity of different mesh will have different degrees of decline: generally, the largest mesh opening is, the greater will the strength decline; conversely, the smaller mesh opening is, the smaller will the strength decline).
Q:What are the advantages and disadvantages of mesh for thermal insulation system?
The advantage is anti-cracking while the disadvantage is that if the quality is not good, it will fall off later.
Q:Where to buy Lufeng glass fiber gridding cloth?
this product has very good stability. The glass fiber gridding cloth for internal walls uses glass fiber as main material. From value perspective, nearly thirty percent of the gridding cloth for external walls uses middle-alkali or alkali-free gridding yarn as raw materials. Then it is used for increasing tension between the cement and building walls.
Q:What's the mesh of glass fiber gridding cloth?
The standard mesh specifications should include the mesh size and mesh number and they should correspond to each other. For example, 100 meshes refers to 100 meshes in each inch. Mesh size: 4.75mm Standard mesh number: 1 Mesh size: 4.00mm Standard mesh number:2 Mesh size: 3.35mm Standard mesh number: 3 Mesh size: 2.80mm Standard mesh number: 4 Mesh size: 2.36mm Standard mesh number: 5 Mesh size: 2.00mm Standard mesh number: 6 Mesh size: 1.70mm Standard mesh number:7 Mesh size: 1.40mm Standard mesh number: 8 Mesh size: 1.18mm Standard mesh number: 16 Mesh size: 1.00mm Standard mesh number:18 mesh size: 0.850mm Standard mesh number: 20 Mesh size: 0.710mm Standard mesh number: 25 Mesh size: 0.600mm Standard mesh number: 30 Mesh size: 0.500mm Standard mesh number: 35 Mesh size: 0.425mm Standard mesh number: 40 Mesh size: 0.355mm Standard mesh number: 45 Mesh size: 0.300mm Standard mesh number: 50 Mesh size: 0.250mm Standard mesh number: 60 Mesh size: 0.212mm Standard mesh number: 70 Mesh size: 0.180mm Standard mesh number: 80 Mesh size: 0.150mm Standard mesh number: 100 Mesh size: 0.125mm Standard mesh number: 120 Mesh size: 0.106mm Standard mesh number: 140 Mesh size: 0.090mm Standard mesh number: 170 Mesh size: 0.0750mm Standard mesh number: 200 Mesh size: 0.0630mm Standard mesh number: 230 Mesh size: 0.0530mm Standard mesh number: 270 Mesh size: 0.0450mm Standard mesh number: 325 Mesh size: 0.0374mm Standard mesh number: 400 A negative sign added before the mesh number refers that the mesh can leak out . For example, -100 meshes +200 meshes refers that these particles can be leaked out in 100 mesh size to 200 mesh size.
Q:Does it is required to paste mesh in which has ben pasted with wallpaper?
Otherwise, the later wall cracks will also affect the wallpaper. Now, the walls has been re-covered with cement. Intend to shovel all red bricks and then cover cement.
Q:How to distinguish glass fiber gridding cloth?
General speaking, the difference of rolled glass fiber gridding cloth is the color of both ends. If both ends are blue-green, then the gridding cloth is non-alkali glass fiber product. If slightly blue-green, then middle-alkali glass fiber product. If white, then high alkali glass fiber product. Look carefully to tell.
Q:What's the use of alkali resisting glass fiber gridding cloth for external walls?
On the one hand it can effectively increase the tensile strength of the protective layer, but it often selects some waste transparent plate glass, at the same time it should be troweled. It costs about 60 yuan. The retention rate of alkali resistant tensile breaking strength should be no more than 50%. Therefore the alkali glass fiber gridding cloth plays an important function and role in outer insulation system. The external angle should be at 200 mm or more. The alkali-resistant glass fiber gridding cloth purchased should be confirmed to be qualified before using: the lap width between alkali grid cloth lap width should be no less than 50 mm: 3×3×45 grams, 5×5×145 grams.
Q:How to calculate mesh content?
The price of mesh material from high to low is successively gold crucible yarn. It is usually from 80 grams to 300 grams per square meter, from a few cents to a few dollars a month. Now the most common is imitated gold pot yarn.
Q:What functions does fiberglass wall mesh have ?
Fiberglass wall mesh functions well. On the one hand, it can effectively increase the tensile strength of the protective layer, on the other hand, because the stress can be effectively dispersed, it can disperse original wider cracks into smaller ones, thus reaching the effect of anti-crack. Surface coating materials and coating amount has more important significance on alkali resistance of fiberglass mesh while glass fiber has decisive significance on the long-term alkali resistance.
