建筑物被称为人类文化的纪念碑。建筑物作为城市市容街景的立体因素和文化景观,是人们视觉最多、最突出的物体,它的美与丑,对市容环境的好坏构成主导作用。由于建筑物表面长期受到物理的、化学的或生物的作用而形成的污染物或覆盖层称为污垢。这些污垢不仅影响建筑的清洁美观,而且会缩短建筑物的使用寿命。保持建筑物的清洁美观,对美化市容整体环境,促进精神文明建设和经济发展有着重要意义。
The building is called a monument to human culture. As the three-dimensional factors and cultural landscape of urban streetscapes, buildings are the most visible and prominent objects. Their beauty and ugliness play a leading role in the quality of city appearance and environment. The contaminants or coverings that form on the surface of a building due to its long-term physical, chemical, or biological effects are called dirt. These dirt not only affect the clean appearance of the building, but also shorten the useful life of the building. Keeping buildings clean and beautiful is of great significance to beautifying the overall environment of the city and promoting the construction of spiritual civilization and economic development.
