    Core tip: performance test method: ① routine performance test Test according to the requirements of flexible crack resistant putty specified in JG 158-2004 "rubber powder polystyrene particle external wall external insulation system" ② Determination of thermal conductivity The elastic putty is scraped on the plastic plate, the thickness is more than 2 mm, and after drying, three standard circular shape test samples with a radius of 12 mm are made The thermal conductivity is measured by lfa477 laser scattering thermal conductivity meter, and the average value is calculated ③ Phase change temperature control performance test The EPS thin plastering external insulation system is applied to the external surface of the wall, Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings: performance test method: ① routine performance test shall be conducted in accordance with the requirements of flexible crack resistant putty specified in JG 158-2004 "rubber powder polystyrene particle external wall external insulation system" ② The measurement of thermal conductivity the elastic putty is applied to the plastic plate, the thickness is more than 2 mm, and after drying, three standard circular shape test samples with a radius of 12 mm are made The lfa477 laser scattering thermal conductivity meter is used to measure the thermal conductivity, and the average value is calculated ③ The phase change temperature control performance test adopts the simulation test method The EPS thin plastering external wall external insulation system is placed on the sunny side of the wall, with the specification of 3 m × 3 m, in which 1 / 2 of the same formula putty without paraffin is applied as the counterpart (sample 1), and 1 / 2 of the same formula putty with octadecane wax is applied (sample 2), with the thickness of the putty layer of 2 mm At 2:00 p.m on a sunny day and at 35 ℃, the surface temperature of No 1 and No 2 samples was measured and the temperature difference was calculated; at 5:00 a.m and at 20 ℃, the surface temperature of two samples was measured and the temperature difference was calculated by the same method Performance test results: according to the test standards of the test items, there is no caking in the container, and it is uniform and consistent with the construction of scratch coating and barrier free, and it is consistent with the burnability of hand grinding, and it is more consistent with the drying time (surface dry) / h ≤ 5 3, the initial drying crack resistance (6 h), no crack, no crack, no water resistance (96 h), no abnormality, 261 h, no abnormality, alkali resistance (48 h), no abnormality, 96 h, no abnormality Water absorption / [g · (10 min) - 1] ≤ 20.65 bonding strength / MPA standard state ≥ 0.60.83 freeze-thaw cycle (5 times) 0.40.68 low temperature storage stability (- 5 ℃, freezing for 4 h) no change, scratch coating barrier free in line with elongation at break /% standard state -- 187-10 ℃ -- 42 heat treatment -- 95 coating family is focused on coating, diatom mud, paint coating, coating process, News and information of fire retardant coating, coating, diatom mud, paint coating, coating technology, decoration knowledge and decoration effect map of fire retardant coating,
