    目前,无尘车间普通选用整体性好、刚性强的水磨石空中。为了防止尘土、细菌积聚、滋生,这种空中须避免开裂和返潮,在施工中可采取夯实回填土,加厚地坪、选用优质水泥(水泥砂浆基底的水泥标号不得低于425号),恰当配筋(对大面积厂房而言)等措施来避免空中开裂;为避免空中返潮,施工中则可采取加厚混凝土层和碎石层,湿度高的地域增加防水层(如一毡二油)等措施。有防腐请求的空中可采用聚酯砂浆整体地坪,由耐腐蚀的不饱和聚酯为胶粘剂,以石英砂或重晶砂为填料混合而成,能耐酸碱,有良好的化学稳定性和耐腐性。药厂中较常用的是以下几种空中面层。
    At present, dust-free workshops generally choose terrazzo air with good integrity and strong rigidity. In order to prevent the accumulation and breeding of dust and bacteria in the air, cracking and moisture regain should be avoided. In construction, measures such as compacting backfill soil, thickening floor, selecting high-quality cement (cement mark of cement mortar base must not be less than 425), proper reinforcement (for large-scale factory buildings) and so on can be taken to avoid air cracking; in order to avoid air moisture regain, thickening coagulation can be adopted in construction. Soil and gravel layers, high humidity areas to increase waterproof layer (such as felt oil) and other measures. The whole floor of polyester mortar can be used in the air with anti-corrosion request. It is made of corrosion-resistant unsaturated polyester as adhesive and quartz sand or barite sand as filler. It can resist acid and alkali, and has good chemical stability and corrosion resistance. The following air surface layers are commonly used in pharmaceutical factories.
    (1)水磨石空中:整体性好、润滑、不易起尘,可冲洗且防静电;缺陷是无弹性。常用于请求经常擦洗的分装车间、针片剂车间、实验室、卫生间,更衣室、结晶工段等。
    (1) Terrazzo air: good integrity, lubrication, not easy to dust, washable and anti-static; defect is inelastic. It is often used in packing workshop, needle tablet workshop, laboratory, bathroom, dressing room, crystallization section and so on.
    (2)塑料空中:润滑、略有弹性、不易起尘、易擦洗清洁、耐磨、耐腐蚀,但易产生静电,受紫外线映照易老化。因而不宜用于经常采用紫外线灯灭菌的场所。普通用于更衣室、包装间、化验室等房间。由于塑料板与混凝土基层的伸缩性能不同,不宜用于大面积车间,否则会惹起起壳现象。

    (2) Plastic air: lubricated, slightly elastic, not easy to dust, easy to scrub and clean, wear-resistant, corrosion-resistant, but easy to generate static electricity, easy to aging by ultraviolet radiation. Therefore, it is not suitable to be used in places where ultraviolet lamp is often used for sterilization. Usually used in dressing rooms, packaging rooms, laboratories and other rooms. Because of the different expansion and contraction properties of plastic slab and concrete base, it is not suitable for large-area workshop, otherwise it will cause shell phenomenon.
    (3)耐酸瓷板空中:用耐酸胶泥贴砌,能耐腐蚀,但质较脆,经不起冲击,破碎后则降低耐腐蚀性能。这类空中可用于原料车间中有腐蚀介质的区段,由于施工复杂、造价高,宜用于有腐蚀介质滴漏的部分范围运用。例如,将有腐蚀介质的设备集中布置,然后将这一局部空中用挡水线围起来,挡水线内部用此种空中铺贴。
    (3) acid-proof ceramic board in the air: it can resist corrosion by pasting with acid-proof cement, but its quality is brittle, it can not withstand impact, and its corrosion resistance is reduced after crushing. This kind of air can be used in the corrosive medium section of the raw material workshop. Because of its complex construction and high cost, it is suitable for some areas where the corrosive medium drips out. For example, equipment with corrosive media will be centralized, and then this part of the air will be surrounded by a water retaining line, which will be laid in the air inside the water retaining line.
