The Mesh is a material for insulation which can resist crack. The cracking resistant mortar is an antimitotic agent made up of by polymer emulsion and admixture. The cement and the sand mixed together according to a certain proportion can become the mortar that can make a certain deformation and resist cracking. It is mainly used for the thermal insulation of the external wall or the thermal insulation of the interial wall, the external cover of polyphenyl board and extruded sheet.
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.
The cracking resistant mortar Mesh are used for the external wall thermal insulation polystyrene?board, extruded sheet bind and to prevent crack. The recipe is: The cement 350 kg, 700 kg of sand 40-70 purposes, dispersible powder of 15-20 kg, HPMC2 kg, cracking fiber 2-5 kg, 3 kg of lignin, water reducer to 2 kg.
