1. The material preparation: Polystyrene foam board, the special adhesives, one-component polymer mortar, alkali-resistant fiberglass mesh, plastic bolt up, polystyrene foam rods and water. 2. The tool preparation: Electric wire cutter or wallpaper knife, handsaw, ink fountain, 2m guiding ruler, ruler, wood beam, tape, motor stirrer, trowel, internal and external corners small brush, the plastic mixing bucket, the raw emery paper, 2m power board 3. The technological process: The first step: With the special sticky adhesive pre-turning bag mesh. The second step: The stick polyphenyl insulation board. The third step: The drilling and fastener installation Step Four: The grinding and leveling of the surface of the insulation board. Step five: The polymer mortar. Step Six: The polymer mortar of the ground floor. Step Seven: The buried quote Mesh Step eight: The plastering layer polymer mortar Step 9: Acceptance
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.
Process 1: The grassroots cleanup→ The slope of the snap?line→ To fix the base of the root→ The construction of the moisture barrier→ The pavement of the insulating layer→ To smooth the leveling blanket→ The cleanup the base To prefabricate or cast the surface of the concrete structure, you should clean the sundries and dust. 3. The elastic line to find the slope: To find the direction of the slope according to the disign of the slope and the direction of the water flow, and make sure the thickness of the insulation. 4. To fix the base of the root: The structure of the base of the tube is before the construction insulation, and it should be filled by the fine aggregate concrete. 5. The gas barrier layer construction: After the second to the fourth processes are completed, the design requirements of the gas barrier layer become solid. The gas barrier layer should be built according to the design to brush evenly and completely.
The standards of the construction technology of the roofinginsulating layer(1001-1996) The Scope This technology is applicable to industrial and civil engineering construction. The roof takes use of the loose and board-like thermal insulation material loose and overall cast-in-place thermal insulation materials insulating layer. Preparation for construction 2.1 The materials and requirements: 2.1.1 The technical performance of density and thermal conductivity, which must meet the design requirements , the regulaltions of the construction, and the test data. The loose insulation materials should use the inorganic material, for example, you should first make the antiseptic treatment when choose the organic materials. 2.1.2 Materials: 2.1.2.1 Bulk material: The particle size of slag or grain slag is generally 5 ~ 40mm. It shall not contain stones, soil blocks, heavy slag and the not burn out coal. The bulk density is 500 ~ 800kg / m3, and the thermal conductivity is 0.16 ~ 0.25W / m?K. The heat conductivity coefficient of the expanded vermiculite is 0.14W/m?K. 2.1.2.2 The board-like heat insulation materials: The products should have the certification of leaving factory.The thicknes and the spectifications should be uniform with the requirements of the design. The appearance should be neat; The density, thermal conductivity, and strength should meet the design requirements. a. The foam concrete blocks: The apparent density should not be more than 500kg / m3, and the compressive strength should not be less than 0.4MPa; b. The aerated concrete blocks: The apparent density is 500 ~ 600kg / m3, and the compressive strength should not be less than 0.2MPa; c. polyphenyl board: The performance density should less or be equal to 45kg / m3. The compressive strength should not less than 0.18MPa. The thermal conductivity is 0.043W / m? K.
