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:I am a worker using glass silk to weave mesh. What harm does long-term work do to body?
Glass fiber itself is not toxic, but the woven mesh trimming process produces glass dust. If long-term toleration, you will have lung problems. You should wear a dust mask in dust wroking environment such as dip and lime. If necessary, you should also wear gloves.
Q:What is the function of epoxy resin mesh
it is mainly used for the casting transformer and electric reactor, soaking in the epoxy resin, and the mesh of H level epoxy glass is using the alkali-free glass fiber with high insulation grade, no partly emission and no bubble in the interior. The product is impregnated throughly in the epoxy resin, solidified and sizinged by drying, and the terylene interweaving to the square opening gridding and the gray cloth is dehydrated by high temperature.
Q:As for the latitudinal tension and longitudinal tension of alkali resistant glass fiber gridding cloth, which is larger?
Longitudinal woven technique often refers to cross woven technique. Secondly, latitudinal yarn is thick yarn. The strength of longitudinal yarn is greater than the latitudinal yarn: currently weaving mill uses pre-rolling longitudinal beam. Moreover, the longitudinal yarn often is joint yarn, so the longitudinal tension is larger and the strength is greater than that of plain weaving.
Q:How much does mesh paving cost??
Around ¥10.
Q:What are the construction technologies of the thermal insulation material Mesh?
The Mesh is based on the C-glass or alkali-free glass fiber which is made by alkali-resistant coating. The products are with high strength, good alkali resistance, playing an important role in the structure of the insulation system and mainly to prevent cracks. Because of its excellent resistance to acid, alkali and other chemicals and the good performance of the tensile strength warply and weftly, it can make the stress of the external wall insulation system dispersed uniformly. And it can avoid the collision outside the momentum, the squeeze caused by the entire insulation deformable structure so that the insulation layer has a high impact force strength, and easy for the construction and quality control, acting as a "soft steel" in the insulation system.
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:If fiberglass mesh bent, how to straighten it up?
First, from the perspective of raw material, it can be divided into the platinum pot and clay pot. Generally the softness and hardness of clay pot products is difficult to control, because clay pot products are generally coated with urea-formaldehyde resin adhesive, while platinum pot products are coated with latex, so its quality is easy to be controlled. Clay pot products only have two states, namely,hard and soft. One is hard, when the product is slightly positioned, but texture is a little brittle, has a poor pulling resistance and easily gets broken off. The other is soft, such products have relatively greater resistance, but are not positioned, so as for the clay pots coated with urea-formaldehyde resin adhesive, their hardness or softness and positioning are mutually contradictory. That is, hard product has better positioning, but possess a smaller tensile force, while soft product has poor positioning, but better tensile force . But as for platinum pot coated emulsion products, their hardness and softness is easy to be controlled, but has to stay within a certain range, the extreme of either is not conducive to construction. To ensure the positioning, the product's hardness and softness in certain range is adjustable, if too hard, the hair nets would be very bad to live with mortar, because a hard product itself has a certain tension, it is difficult to control the mesh. Not soft products in the construction could not be hooked on, so the hardness and softness must be moderate, products with good positioning are easy to be constructed. Just take a trowel with mortar wipe live on the line, if the positioning is not good, when wiping with a trowel, the line will move back and forth, which will affect the overall effectiveness of the insulation and construction.
Q:What is the function of interior design mesh?
Its raw material is medium alkaline or non-alkaline glass fiber yarn. Modern buildings are made from concrete or bricks. The features like crack resistance can be restored. This is lightweight wall.
Q:External thermal insulation is using alkali-resistant mesh: does the fracture stress is the same with breaking elongation
confirming the node has the potentiation to the tensile breaking strength of mesh, analyzing the influence factor to the alkali resistant breaking strength; measuring and testing the node strength of the mesh. from the test result we know that the alkali resistant coating has a certain reinforcement to the mesh tensile breaking strength. through the comparison of the the alkali resistant coating mesh soaking in the alkali resistant mesh alkali liquor, and the alalysis of the SEM atlas and the test of the tensile breaking strength, the friction force of the fibers and the quality of alkali resistant coating surface. the mesh alkali resistant tensile breaking strength is mainly determined by the glass fiber tensile breaking strength.
Q:As for steel wire gauze and gridding used for thermal insulation of external walls, which is better?
Using "hot galvanizing steel wire reinforced structure" can effectively balance the crack resistance and grassroots strength of brick, greatly improving the strength of the brick pasted at the grass-roots level. Smooth surface of galvanized welded wire gridding cloth and glass fiber gridding cloth is widely used in building wall insulation. Glass fiber gridding cloth is made of alkali resistant glass fiber mesh cloth by cold plating (plating). Gridding cloth is mainly used for brush painting, protecting insulation layer and strengthening protection layer, thus it is widely used for thermal insulation of building internal and external walls.
