Construction preparation technical preparation 4.1 4.1.1 YTW insulation works construction plans, design specifications and other design documents must be reviewed by the audit agency FIG. Design changes may not reduce building energy-saving effect, and shall be subject to the original construction drawing design review body before the implementation of design changes should go through the formalities, to be confirmed by the supervision or construction units. 4.1.2. Factory material certification, factory inspection reports, the approach reinspection reports and type of inspection reports and other documents complete quality and compliance. 4.1.3 with the construction program, supervision of the work program;. Construction of technical tests (operating instructions) has been completed. 4.2 materials approach and storage 4.2.1 should be required when the materials approach site acceptance, heavy bag inspection of various materials, single bag volume is qualified, packing bags is broken, verification material specifications, models, technical parameters whether the certificate, inspection reports and other quality documents matched within the validity period, etc., then the required reinspection site. 4.2.2. The material stored on-site conditions 1.YTW insulation materials are paper-plastic bag, carrying prohibited throw, avoid pierced bags. 2.YTW insulation materials, flexible water-resistant putty, tile adhesive mortar should be stored in dry and ventilated warehouse, the Treasury should be waterproof, moisture-proof measures. Storage period 3.YTW insulation materials should not exceed six months. (And do not exceed the material standards of validity) characteristics of thermal insulation material [1] industrial equipment and piping insulation, the use of airgel insulation measures and first used in NASA space suit developed insulating liner. It has a low thermal conductivity, low density, high flexibility, fire water and other characteristics. Its thermal conductivity at room temperature 0.018W / (K · m) and absolute waterproof, insulating performance of traditional materials 3 to 8 times. [2] has a low thermal conductivity, low density, high flexibility, fire and water and other characteristics on the insulating liner. Nanyang yt inorganic light weight wall insulation materials, general 10-96kg / m3,20kg / m3 or less for the carpet, 24-48kg / m3 as the hard plate, 48-96kg / m3 for the hard plate, wherein 48kg / m3 can be ceiling Nanyang inorganic wall insulation material costs, a softening point of 500 ° C, and incubating 300 ° C, the United States a larger amount, k = 0.9. Calcium silicate insulation products domestic 1970s successfully developed inorganic wall insulation materials with high compressive strength, low thermal conductivity inorganic wall insulation materials Anhui Which is good, convenient construction, reusable features, is widely used in the power system . Most popular for domestic small cottage, after successive introduction of four production lines from the United States, advanced technology, instant speed thrown into fiber, needle felt dry, stable quality, temperature 800-1250 ° C. Features: acidity derivative 2.0 above, high temperature, general chemical pipeline more than 1000 ° C, you must use this material. Melting temperature at about 2000 ° C.
