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

How to understand CORE MAT description:

Example:
250BWR500B250

Q:How much money do I need to run a small mesh loom factory ?: A 2-meter-wide standard loom costs about ?12,000 each. 2 or 3 looms would be enough. You also need a drying oven, about ?10,005, a warping machine,about ?3,000, beating crusher costs ?2,000. Then you can start on.

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:Soft or hard glass fiber gridding cloth used for walls, which is better?: It depends on the quality. Generally the price of gridding cloth for external wall is 1 yuan/㎡.

Q:For wall slot, is seam paper tape or anti-cracking mesh suitable for joints?: Dacron cloth is more anti-cracking.

Q:What is the function of the cracking resistant mortar Mesh?: The cracking resistant mortar is a bag of ready-mixed material, it can be used for the construction just after stirring with the water. The aggregate of the cracking resistant mortar is very rough, so it is not easy to crack. In addition to the mixture of the wood fiber and other mortar admixture, it can form a three-dimensional and multi-dimensional mesh structure. It can relieve the stress flexibilely so as to remove the crack brought by the temperature difference.

Q:What is the standard of external wall thermal insulation mesh?: Current national external walls thermal insulation mesh technical standards (JG): The glass grid warp-wise and weft alkali resistant tensile breaking strength are not less than 750N / 50mm, the retention?rate of alkali resistanttensile fracture strength is not less than 50%, the weight of per square meter ≥130 grams. The JG glass grid warp-wise and weft alkali resistant tensile breaking strength are not less than 1250N / 50mm, the retention?rate of alkali resistant tensile fracture strength is not less than 90%, the weight of per square meter ≥160 grams. The retention?rate of breaking strength and alkali-resistant strength: It is generally known that breaking strength and alkali-resistant strength retention rate is an important performance of fiberglass mesh. Breaking strength is inseparable to the count or weight of glass fiber. Fiberglass mesh for exterior outer insulation systems is generally about 130 grams per square meter on the current market, intensity is generally low, if you want to achieve this requirement, the weight should be more than 160 grams per square meter. Standard mesh with good quality is based on the platinum glass?fiber, both in the selection of materials and weaving processes are more exquisite. Coating emulsions have good alkali resistance. Excellent alkali resistance and high warp and weft tensile strength make the product has a good feeling and good construction fitting, to a large extent, reduce the amount of plastering mortar.

Q:modified asphalt polyester and glass?fiber mesh strengthening waterproof roll is made of the good performance composite tyre.: modified asphalt polyester is one kind of low quality waterproof roll which using the gelatine powder to take the place of high polymer. glass?fiber mesh reinforced waterproof roll is distinguished by the waterproof roll texture of the tyre

Q:How to tell the quality of mesh cloth?: The worst fiberglass mesh is very cheap and breaks at two folds. The process is made of clay crucibles. Fiberglass is usually made from some beerBottles made of waste glass. It is prohibited by the state, and its surface coating is not alkali resistant emulsion. From an intuitive point of view: work is relatively rough, generally in the citySell more, often short, easy to shift, and easy to stab the skin. This type of mesh cloth is used in inadequate insulation quality. contact

Q:In what circumstances do you need to paste the mesh, if not, it is okay?: Mesh is used in external wall thermal insulation building, it will not have a "thermal bridges" or "cold bridges" phenomenon, which has a good effect on building energy efficiency. It is toasted by the construction! In winter, when indoor heat through the mesh wall insulation materials will be isolated and preserved, and when the room temperature drops down, the heat of wall will be released, so as to adjust the indoor temperature; in summer, exterior mesh insulation will also prevent the sun's heat radiation and external incoming interior, so as to keep warm in winter and cool in summer of the building indoor environment, residential indoor environment and physical performance have been significantly improved.

Q:What is the construction method of external wall thermal insulation mesh: 1, It needs specially-assigned person to compound the polymer mortar in order to ensure the quality of stirring. 2, open the bung by contrarotate, and then remix the adhesive with a stirrer or other tools to prevent the parting phenomenon of binder, you should stir moderately, so as not to render quality problems. 3, polymer mortar mix ratio: KL Binder: 425# sulphate aluminium cement: Sand (with a 18 mesh screen): 1: 1.88: 3.25 (weight ratio). 4, After cement and sand are measured by the bucket, pour into iron gray groove, and then mix evenly. And pour into binder in mix proportion, stirring evenly into gruel to prevent dissociation. It can appropriately add water due to the workability. 5, water is the concrete water. 6, polymer mortar should be used with the distribution, the deployed polymer mortar preferably is better to run out within one hour. Polymer mortar should be placed in a cool place to avoid sun exposure.
