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:The difference between the gridding cloth and iron gauze What materials should be used for thermal insulation of external and internal walls?
The current technical standards (JG) for thermal insulation gridding cloth of external walls: alkali resistant fiberglass mesh warp weft tensile breaking strength: 750 n / 50 mm, alkali tensile breaking strength retention rate: 50%, weight/㎡: ≥130 grams JG alkali resistant fiberglass mesh warp weft tensile breaking strength: 1250 n / 50 mm, alkali tensile breaking strength retention rate: 90%, weight/㎡: 160 grams, or breaking strength and alkali resistance strength retention: as all know, the breaking strength and alkali resistance strength retention, important performance: breaking strength, glass fiber gridding cloth and glass fiber count or weight Currently the glass fiber gridding cloth for thermal insulation of external walls is about 130 grams/㎡ with relatively lower quality and 160 grams/㎡ with standard quality. With platinum glass fiber as base material, gridding cloth is coated with emulsion with good alkali resistance and high tensile resistance in the bidirection of warp and weft, thus featured by smoothness and reducing the mortar amount.
Q:What are the requirements for wall insulation fiberglass mesh?
National technical standards of external wall thermal insulation mesh (JG): The fiberglass mesh warp-wise and weft alkali tensile strength shall not be less than 1250N / 50 mm, alkali tensile fracture strength retention rate shall not be less than 90%, the weight per square meter shall be equal or greater than160 grams. The JG fiberglass mesh warp-wise and weft alkali tensile strength shall not be less than 1250N / 50 mm, alkali tensile fracture strength retention rate shall not be less than 90%, the weight per square meter shall be equal or greater than160 grams. Breaking strength and alkali-resistant strength retention rate: It is generally known that breaking strength and alkali-resistant strength retention rate is an important property of fiberglass mesh. Breaking strength and glass fiber count or weight are bound together.
Q:For the mesh of cleaning wall, is nylon fabric or fiberglass mesh better?
Fiberglass mesh is absolutely better. Owing to its no-ductility, the cleaned wall is not easy to crack.
Q:how to do when the mesh touches the skin
it also has the method of wrapping by the adhesive tape and pulling open, there has no other ways to take two days to cure the skin, if it can be saw by eyes, you can take the superciliary clamp to pick it out . it should be the glass fiber prick into the skin.
Q:Can wall bricks be pasted on the indoor glass fiber gridding cloth?
Yes. Glass fiber gridding cloth is used for roofing waterproofing and wall or board reinforcement such as gypsum and mosaics.
Q:How to use resin and good glass fiber gridding cloth?
Resin has better liquidity, so the dipping time is longer; if possible, the gridding cloth should not be dense. Using coupling agent before dipping may have a better boding effect.
Q:Alkali resistant products of gridding cloth
With middle-alkali or alkali-free glass fiber gridding cloth as base material, glass fiber gridding cloth is made by processing with alkali resistant coating. It is featured by high strength, good alkali resistance and crack resistance. It plays an important role in insulation system. Due to its excellent excellent resistance to corrosion of chemicals such as acid and alkali and high tensile resistance in the bidirection of warp and weft, it can evenly disperse stress of external wall insulation system and prevent the deformation of the whole insulation structure caused by shock and squeezing of external force, thus making it featured by high shock resistance and easy construction and control. Therefore, it plays a role of soft rebar in insulation system.
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:Does it need to whitewash while pasting fiberglass mesh of wall plastering?
Whithwashing is a must. No matter what is added outside, whitewashing is still necessary.
Q:What is the difference of the interior wall mesh and external wall mesh?
Mesh is divided into interior and exterior wall mesh mesh cloth, apply to different places and sites, the main difference between them is the different material. The interior wall mesh is with the glass fiber fabric as the base material, made by a series of processes. It can be used to repair various damaged wall, and it is an ideal material for GRC wallboard. The unit of weight is relatively light, and the tensile strength of the quality is also relatively small. The external mesh is mainly with the raw material of alkali, and then becoming a Mesh through various processes. It is with a very strong stability and great intensity which is easy for the construction. It usually works for thermal insulation, being a professional mesh. Compared with the interior wall, it is a collection of fibers made with a good flexibility. Due to the differences of the local environment, the tensil force of the exterior wall is much better than the interior wall.
