防水卷材——施工方便、工期短、成形后无须养护、不受气温影响、环境污染小,层厚容易按设计要求掌握,用材计算准确、施工现场管理方便,不易偷工减料,层厚均匀,空铺时能有效地克服基层应力(在基层发生较大裂缝时能保持防水层整体性)。
Small environmental pollution waterproof sheet, convenient construction, short construction period, after forming without maintenance, not affected by the temperature, layer thickness, easy to master according to the design requirements, material calculation, construction site management is convenient, not easy to cut corners, layer thickness, air can effectively overcome the primary stress shop (to maintain overall waterproof layer in the occurrence of grassroots large cracks).
防水涂料——任何复杂基层都可做成连续整体的防水层;设备简单,施工技术容易掌握。涂料防水层与基层具有100%的粘结面(裂缝、节点等部位使用加强层空铺法除外)。涂料防水层在可使用年限内的漏水,大多为基层开裂宽度超过防水涂层的可延伸幅度,漏水原因和形成漏水的部位极易发现,保修非常方便,只要少量防水材料修补裂缝和损伤部位即可。高品质的防水涂料可在背水面防水获得成功。上海尤鲸的部分防水涂料可在潮湿基层施工并形成防水层。
Waterproof coating - any complex base can be made into a continuous whole waterproof layer; the equipment is simple and the construction technology is easy to master. The coating waterproof layer and the base have 100% bonding surface (except for the cracks, nodes and other parts using the strengthened layer method). The leakage of coating waterproof layer in the useful life is mostly the extension of the base layer, which is more than that of the waterproof coating. The cause of leakage and the location of the leakage are easy to find. The warranty is very convenient, as long as a small amount of waterproof materials repair cracks and damaged parts. High quality waterproof coatings can be successfully waterproof on the back of the water. Some waterproofing coatings for the Shanghai whale can be built in wet base and form a waterproof layer.
缺点:
Shortcomings:
防水卷材——需根据防水基层的形状而进行量体截衣,对于外形复杂的基层需多块拼接,防水卷材相互搭接处的粘结难度较大;完全绝对的密封将成为主要难题,漏水隐患最大;防水卷材在施工后的保护和漏水后的维修亦是难题,任何部位的贯穿性破损,脱胶、漏胶(那怕是只有一处),整个与其相连贯层面的防水功能都将全部衰失,如果不能找到破损和缺陷部位,则局部修补就不可能,那么只有重做防水。
Waterproof sheet, and the amount of required body clothing according to the layer shape, for the complex shapes of grassroots need splicing, waterproofing materials overlap the bonded difficult; absolute seal will become a major problem, the biggest risk Water Leakage; waterproof protection in the construction and maintenance is also a problem after Water Leakage and any part of the penetrating breakage, degumming, leakage of adhesive (even if it is only a function of the whole and waterproof), coherence level will be all decline, if you can not find the damaged and defective parts, local repair can not, then only redo waterproof.
防水涂料——涂料需一定时间的物理和化学反应固结后才能生成防水层;部份防水涂料在固化过程中产生有害气体释放,对人体有害。有的防水涂料一个防水层的完工需要多遍涂刷,每遍涂刷要有一定的间隔时间,因此防水层的最后完成要较长时间;防水涂料的施工过程中,现场管理显得十分重要,偷工减料、粗制滥造在管理疏忽的情况下将会有机可乘;涂料防水层厚度是根据施工时的涂布遍数决定的,除了涂布遍数外,涂料本身的固含量是成膜厚度决定因素。
Waterproofing coatings -- Coatings need physical and chemical reaction after a certain period of time to form waterproof layer after consolidation. Some waterproof coatings release harmful gas in curing process, which is harmful to human body. Have a waterproof coating waterproof layer completion requires many times each time brushing, brushing should be there is a certain interval of time, therefore, the waterproof layer finally completed a long time; the construction process of waterproof coating, site management is very important, and will take advantage in the management of Jerry crudely made case of negligence; the waterproof coating thickness is according to the construction of the coating times determined, in addition to the number of times of coating, solid content of the coating itself is a determinant of film thickness. |
