材丙烯酸漆吸水性质的延伸和导热能力料的抗压强度与加工工艺、材料孔隙率等有密切关系。设备及管道保温技术导则)GB427292规定硬质制品抗压强度不应小于0.3MPa.对于软质、半硬质及松散状绝热材料，~般受到压缩荷载时不会损坏，因此抗压强度未作规定。
There is a close relationship between material compressive strength and processing technology, material porosity. Insulation technology guidelines for equipment and pipeline) provisions of GB427292 hard product compressive strength shall not be less than 0.3MPa. for soft, semi hard and bulk insulation materials, like not damaged by ~ compression load, therefore the compressive strength is not specified.
抗折强度是材料在受到弯曲负荷作用下破坏时，单位面积上所受的力偶矩。5含水率 保温材料吸收水的性质称为吸水性。材料单位体积吸水的程度用吸水率来表示。保温材料的吸湿性，对其保温效果有很大的影响，吸收的水蒸气遇冷会凝聚成水或结成冰，从而大大地提高了其热导率，甚至引起材料开裂，破坏保温结构。
Flexural strength is the material failure under bending load under the action of unit area, moment couple by the. Properties of 5 moisture content of insulation material absorbs water known as absorbent. Unit volume of material absorption degree to represent the rate of water. Hygroscopic thermal insulation material, has great influence on the effect of thermal insulation, freeze water vapor absorption can condense into water or ice, thereby greatly improving the thermal conductivity of materials, even cause cracking, damage to the insulating structure.
另外，为了降低保温材料吸收的水分，除了施工中应注意防水外，还可以适当地在保温材料中加入憎水剂，如憎水矿棉板和憎水珍珠岩等。正常涂料表面应该是光亮光滑的亚光涂料除外)但有些涂料表面会出现倒光，即涂料膜干燥后表面无光泽，或者有一层橡雾状物凝聚在涂料膜上(有时呈蓝色光彩)其原因是1涂料质量不好或加入的稀释剂太多，稠度大，使漆膜的光泽不持久。
In addition, in order to reduce the thermal insulation material absorption of moisture, but should pay attention to the waterproof construction, can also be appropriate to join the hydrophobic agent in thermal insulation materials, such as hydrophobic water cotton board and hydrophobic perlite. The normal coating surface should be smooth except matt paint bright) but some paint surface will appear inverted light, namely the coating film drying after the surface gloss, or a layer of rubber mist condenses in coating membrane (sometimes blue glow) the reason is the 1 coating quality is not good or adding diluent too more consistency, not lasting gloss of the paint film.
2涂刷的时间掌握不好，底漆没干透就涂刷油漆，使底漆回软失去光泽。3物体表面不平整、粗糙或表面吸油不一致，使涂料膜失去光泽。4施工环境不好，温度太低或受过烟熏使涂料膜失去光泽。5施工环境湿度过大(相对湿度80%以上)挥发性漆膜吸收水分后泛白，失去光泽。
2 time brushing is not well controlled, the primer did not dry brushing paint, primer softened lose luster. The 3 surface is uneven, rough or inconsistent surface oil absorption, loss of gloss of the paint film. 4 the construction environment is not good, the temperature is too low or highly smoked loss of gloss of the paint film. 5 construction of environmental humidity is too large (more than 80% relative humidity) volatile film absorb water white, lose luster.
采取以下预防措施：防腐涂料，一般分为常规防腐涂料和重防腐涂料，油漆涂料中必不可少的一种涂料。常规防腐涂料是一般条件下，对金属等起到防腐蚀的作用，保护有色金属使用的寿命；重防腐涂料是指相对常规防腐涂料而言，能在相对苛刻腐蚀环境里应用，并具有能达到比常规防腐涂料更长保护期的一类防腐涂料。
Take the following precautions: anti-corrosion coating, generally divided into conventional anti-corrosion coatings and heavy anti-corrosion coating, a coating of paint in the essential. Conventional anti-corrosion coatings is the general conditions, to prevent corrosion action on metals and so on, the service life of the protection of the non-ferrous metal; heavy anti-corrosion coating is defined relative to conventional anti-corrosion coatings, can be in a relatively harsh corrosive environment applications, and has to reach than a conventional anti-corrosion coatings anticorrosive coating longer protection period.
涂料这个东西挺玄的城府很深，明明各不相同，看起来却都一样。千人一面的铁皮外套;帽子下面是清一色的洁白小脸;抹到墙上去以后，又都展现出细腻的肌肤。但如果不细心比较那些细小的差别，恐怕你就得花冤枉钱了因此，向大家引荐以下我买涂料的心得体验，5大诀窍和3项注意是关键。
Paint this thing quite mysterious Ayutthaya deep, obviously different, looks are the same. A mass of tin coat; the hat is all white face; after wiping up the wall, and exhibit the delicate skin. But if not careful comparison of those tiny differences, I'm afraid you'll have to spend the money. Therefore, to introduce the following I buy paint experience, 5 tips and 3 attention is the key.
五大诀窍 一、材丙烯酸漆买包装最重的将油漆桶提起来，晃一晃，如果有稀里哗啦的声音，说明包装严重不足，缺斤少两，黏度过低，正规大厂真材实料，晃一晃几乎听不到声音。
Five tips to buy a package, most the paint bucket lift up, shake, if there is a crash Bang sound, stating packing serious inadequacy, Quejinshaoliang, viscosity is too low, formal large real, shake, can't hardly hear.
