1987年,由聊城地区公路段投资,在我站沥青厂增设了一套交通部新津筑路机械厂出品的乳化沥青设备,供全区八个县市公路系统乳化沥青使用。由于原设备结构简单,有些关系到产品质量的环节上属人工工艺操作,操作技术难以掌握,产品质量很不稳定,乳液静止有结皮现象,直接影响了乳化沥青的推广应用。1990年,在总结经验教训的基础上,找出产品稳定度不过关的主要原因是:油水配比不稳定造成,其结皮现象主要是贮罐设在地上,易受气温影响,水分蒸发较快,形成表皮自动破乳
In 1987, invested by the highway sections in Liaocheng, an emulsified asphalt plant produced by Xinjin Road Machinery Factory of the Ministry of Communications was added to the Asphalt Factory of I Station for the emulsified asphalt used in the highway system of eight counties and cities in the whole region. As the original equipment structure is simple, some related to product quality aspects of the artificial process operation, operation technology is difficult to grasp, the product quality is very unstable, the static phenomenon of emulsion skin, a direct impact on the promotion and application of emulsified asphalt. On the basis of summing up experience and lessons in 1990, the main reason for finding out the stability of products is that: the oil-water ratio is not stable, the crust phenomenon is mainly caused by the temperature of storage tank affected by water temperature and evaporation Fast, the formation of epidermal automatic demulsification
