The rock wool composite board is made of high quality glass wool and fiber cement board. Standard requirements thermal conductivity W / (m? K) ≤ 0.044 憎 water ≥ 98.0%; water absorption ≤ 5%; thermal load shrinkage ≥ 600 ° C
The thermal conductivity of the product is W/(m?K)=0.043; the water repellency rate is 98.30%; the water absorption rate is 3.6%; the heat load shrinkage degree is 660 °C. 3, superior weather resistance and impact resistance: Composite rockwool veneer is made of high-strength weather-resistant cement fiberboard as a protective layer. Standard density g/cm31.4<D ≥1.7, detection density g/cm3=1.6; standard water absorption ≤28%, detection water absorption rate 21%; standard frost resistance without cracking, no separation, frost resistance, no cracking, no delamination standard Moisture resistance ≤0.23%, moisture resistance test =0.13%; standard flexural strength air dry ≥18MPa saturated water≥14MPa, detection flexural strength air dry=19MPa saturated water=15MPa; standard impact strength≥2.0KJ/m2, detection Impact strength = 4.0KJ/m24 short construction period reduces project cost:
Composite rock wool composite board in actual construction process
Because the connection of the special installation link is not affected by the construction temperature, the construction period is shortened and the cost is reduced.
5, the exterior decorative surface can have a variety of options:
Composite rock wool composite panel exterior finishes are available in a variety of options, such as: fluorocarbon paint, real stone paint, various coatings, metal sheets, imitation stone, ceramic tiles, etc.
Installation step 1 According to the size of the composite rock wool composite board, Φ6 steel expansion bolt anchors are used on the wall (when the composite board is arranged horizontally, two pieces of each board are arranged, and when the composite board is vertically arranged, one card on the upper and lower sides of the board 2) Bonding the rock wool composite board with bonding mortar, the strips are sticky; wipe the 3~5 thick anti-cracking mortar, and press a layer of glass fiber mesh to ensure firmness and reliability. The number of fixtures is set according to the design specifications. 3, the bottom layer of polymer mortar: 1 polymer mortar is prepared with a special binder. The prepared polymer mortar is evenly spread on the rock wool composite board with a thickness of 2 mm 4
, press into the grid cloth:
1. The mesh cloth should be cut according to the length of the working surface. Langfang (rock wool composite board manufacturer and quotation should leave the overlap width. The cutting of the mesh cloth should be carried out in the weft direction.
2. Grid around the hole in the door and window, and the four corners should be reinforced with a layer of mesh cloth. The whole mesh cloth should be overturned around the hole and attached to the mesh.
3. Apply polymer mortar to the front and side of the rock wool composite board at the opening of the hole and the mesh cloth (only the end of the rock wool composite board is coated with polymer mortar). The pre-extrusion mesh is flipped along the thickness and pressed into the polymer mortar.
Product features: insulation board, energy saving, waterproof, decoration and integration. Simple construction, one operation, short cycle, high efficiency, reduced wet work,
Wide application range and low comprehensive construction cost. The external wall insulation board is made up of inorganic fireproof board or fiber cement board, rock wool board or glass wool board, etc.
Class A fire protection standard; integrates functions of heat preservation, waterproofing and veneering. Factory-based production and on-site bonding construction are the preferred materials to meet the current building energy-saving needs and improve the insulation level of industrial and civil buildings. It is also the preferred material for energy-saving renovation of existing buildings.
Construction points:
1
This regulation applies to the inspection and acceptance of the insulation project. The quality acceptance of the finishing layer is in accordance with the "Scope of Acceptance of Building Decoration Factory"
(GB50501-2001) Implementation of the inspection and acceptance provisions for the sub-projects.
2 Check the following documents and records when accepting the project:
1 Construction drawing, design description and other design documents of the thermal insulation board project;
() Material product certificate, performance test report, entry acceptance record and re-inspection report (3) Paste light test report of insulation board sample board; (4) Covert project acceptance report;
5) Construction records, quality inspection and assessment records.
3. The insulation board paste project should be re-examined for the following materials and their performance indicators: (1)
Coagulation time of cement for bonding,
Installability and compressive strength; (2) water retention, frost resistance and impact resistance of the insulation board;
The insulation board paste project should be re-examined under the concealed project: (1) Grassroots treatment. (2) Bonding point and bonding area of ​​the board and the base layer. (3) Anchor installation.
5 Before the construction of the thermal insulation board and during the construction process, the sample parts should be made on the same base layer, and the bonding strength of the insulation board of the sample county should be tested. The inspection method should refer to the “Testing Standard for Bonding Strength of Building Finishing Tilesâ€. (JGJ110-1997) regulations are implemented.
