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 Coating home news: brief introduction: furnace high temperature resistant insulation coating is a kind of energy-saving insulation coating (including ZM high temperature type and ZM normal temperature type) The technology is the world's leading The coating is processed from special silicate solution and selected ceramic hollow beads The coating belongs to inorganic single component coating, without any peculiar smell and harmful materials under high temperature and normal temperature According to different application conditions, high temperature resistant heat insulation coating can be divided into (160 ℃ ~ 1000 ℃, specific gravity is 1200 kg / m3) and (800 ℃ ~ 1700 ℃, specific gravity is 2200 kg / m3) The thermal conductivity coefficient is only 0.03 w / (m · K), which can effectively inhibit and shield radiation heat and heat conduction The inhibition efficiency of heat insulation can reach 90 %Left and right, it can inhibit the heat radiation and heat loss of high-temperature objects, effectively keep the cold of low-temperature objects, inhibit the cooling loss caused by the radiation heat of the environment, and also prevent the occurrence of object condensation The heat radiation and heat loss can be restrained effectively when the high temperature resistant heat insulation coating is applied on the surface of high temperature pipeline, equipment, furnace (inside and outside) and container Features: high temperature resistant heat insulation coating has the characteristics of waterproof, crack proof, fire prevention, sound insulation, flame retardant, insulation, wear resistance, acid and alkali resistance, light weight, convenient construction, long service life, etc ① The heat insulation performance can effectively prevent the heat transfer and keep the inherent temperature and energy of the object, such as heat insulation, cold insulation, antifreeze and reduce thermal radiation ② Adhesion: 100% adhesion, strong adhesion, it can completely bond with the substance and firmly adhere to the surface of the object ③ It can prevent the expansion and contraction of the base material at different temperatures caused by cold / heat, and has good tensile strength and elasticity ④ The hazard has no peculiar smell, does not contain or will not produce harmful VOC substances, carcinogenic substances and other harmful polymers, decomposition products and by-products ⑤ Stable chemical performance is stable, no chemical reaction with any substance, no influence of acid, alkali and corrosive substance ⑥ The ceramic particles of the wear-resistant coating are closely packed, the solvent is strengthened by composite process, and the wear-resistant property is good, and the wear-resistant strength is 3-4 times of that of ordinary steel ⑦ Excellent toughness can effectively

best surface temperature of the painted object or equipment is 15-60 ℃, which can not be directly painted on the surface of the running low-temperature and high-temperature objects The painting environment temperature is higher than 5 ℃, and the construction is carried out in a ventilated and dry place ② The rust, oil and dust on the surface of the object to be painted shall be cleaned, and the construction can only be carried out after the water is completely dry When painting on smooth or strong water seepage objects, it is recommended to first apply ZM transition coating on the objects, and then apply high temperature heat insulation coating after drying ③ The thickness of the first layer is about 0.3 mm In the future, the thickness of each layer can be more than 0.5 mm, but not more than 1 mm In multi coating construction, the subsequent construction can only be carried out after the previous layer is dry, and the construction can be carried out layer by layer until the required thickness ④ If required by the customer, the coating can be applied on the inorganic primer specified by the customer, not directly on the organic primer ⑤ For high-temperature pipes and high-temperature equipment, it is necessary to wait for the coating to be fully cured (the time is generally more than 48 hours) before starting the system The home of coatings focuses on coatings, diatom mud, paint coating, coating process, fire-resistant coating news information and coating, diatom mud, paint coating, coating process, fire-resistant coating decoration knowledge and decoration
