| 沥青是一种棕黑色有机胶凝状物质沥青罐沥青烟和粉尘沥青罐可经呼吸道和污染皮肤而引起中毒，发生皮炎、视力模糊、眼结膜炎、胸闷、腹病、心悸、头痛等症状。经科学试验证明，沥青和沥青烟中所含的3，4苯并芘是引起皮肤癌、肺癌、胃癌和食道癌的主要原因之一。 但是现在能够接触沥青工作的行业，对沥青的防护都应该是按照相关的*标准执行的，一般都会将其对人的伤害降到安全范围内，不知道你是做什么工作的，对沥青的接触程度，所以，你*在计划怀孕前先去检查一下，以确保孩子的健康。沥青罐特点是：加热快、节能、生产量大、用多少出多少不浪费、不老化、操作方便，全部附件都在罐体上、移动、吊装、维修特别方便，固定式非常方便，本产品加热160度的热沥青一般不会超过30分钟青及其烟气对皮肤粘膜具有刺激性，有光毒作用和致肿瘤清除:如果不小心染上沥青试试用氢氧化钠清洗..虽然有毒，但是也不用太担心，一般都不会遇到，粘到皮肤，轻轻除去就可以了，也不会同一种级配的沥青料表面构造深度大，一般是空隙率大；但如果级配不同就不能直接比较了，SMA的表面构造深度比AC料大，但是空隙率还是相对于AC料更小的影响混合料高温稳定性因素：混合料的类型、级配，沥青的性质、用量，集料的粒径、形状、级配、粗集料含量，矿粉的含量、洁净程度，施工条件，气候，荷载增强措施：适当减少沥青用量，选取粘度大、劲度高、粘附性好的沥青，采用合适的集料级配，选取破碎坚硬粗糙的集料更有利于提高混合料的高温稳定性能，矿粉要求洁净，用量宜适宜，施工适当增加压实功，减小混合料空隙率等（中译英）Asphalt is a brownish black organic gelatinous material, asphalt smoke and dust via the respiratory tract and skin pollution caused by poisoning, dermatitis occurs, blurred vision, eye conjunctivitis, tightness in the chest, abdominal disease, palpitation, headache and other symptoms. The scientific test proof, bitumen and asphalt smoke contained 3,4benzopyrene is caused by skin cancer, lung cancer, gastric cancer and esophageal cancer is one of the main reasons. But now able to contact the asphalt working industry, to the asphalt protection should be in accordance with the relevant national standards, the general will be harmful to the safety range, do not know what kind of work do you do, on asphalt degree of contact, so you'd better in planning a pregnancy, before you check, to ensure the health of children. Asphalt tank features are: fast heating, energy-saving, large production capacity, how much waste not, not aging, convenient operation, all the accessories are in the tank, moving, lifting, convenient repair, fixed type is very convenient, this product is heated at 160 degrees heat asphalt generally does not exceed30 minutes green and flue gas on skin and mucous membrane irritation, toxicity and light induced tumor removal: if not careful with asphalt try sodium hydroxide cleaning .. although toxic, but also do not worry too much, are not normally encountered, adhering to the skin, gently remove it, nor the same kinds of gradation asphalt surface structure deep, the general is a large void ratio; but if the gradation of different cannot be directly compared, SMA surface structure depth than AC material, but the void ratio and relative to AC material less impact mixture high temperature stability factors: the type of mixture, gradation, asphalt nature, dosage, aggregate size, shape, gradation, coarse aggregate content, mineral content, clean degree, construction conditions, climate, load enhancement measures: appropriate reduction of asphalt content selection, viscosity, stiffness, good adhesion of Asphalt, using appropriate aggregate gradation, selection of crushing hard rough aggregate is more conducive to improving the mixture high temperature stability performance, slag require clean, should use suitable, appropriate to increase compaction work construction, reduce the porosity of mixture.（图/文http://www.wxfengli.com/） |
