我国随着对内搞活、对外开放政策的实施,带来了建筑业的兴盛,防水沥青材料用量也随之大增,出现了市场缺货的局面,尤其是低软化点沥青更为紧张。为此,一些乡镇企业便利用附近油田采油队常压分馏轻质石油时产生的渣油生产沥青,我们称这类沥青为“地方产非标渣油沥青”。地方产非标渣油沥青是将渣油加温吹气氧化,同时再蒸馏掉一部分柴油、蜡质的剩余物。由于渣油产地和分馏程度不同,贮运加工中又没有严格控制质最的手段,有的甚至还人为地掺入粘土、滑石粉或砂土等杂物,因而质量波动较大。当然一些质量控制好的产品,可达到65号普通石油沥青
With the invigorating domestic policy of opening up to the outside world, the prosperity of the construction industry has brought with it. As a result, the amount of water-proof asphalt material has also risen sharply. There has been a shortage of goods in the market. In particular, asphalt with low softening point is even more tense. For this reason, some township and village enterprises use the residual oil produced by the oil production teams nearby to fractionate light oil to produce asphalt. We call this type of asphalt “non-standard residue asphalt”. Local production of non-standard residue asphalt is the residue is heated and inflatable oxidation, while re-distillation part of the diesel, waxy residue. Due to the different origin and fractionation of residual oil, there is no strict means of controlling the quality in storage and transportation. Some even artificially mixed with debris such as clay, talcum or sand, so the quality fluctuated greatly. Of course, some good quality control products, up to 65 ordinary asphalt
