刮完兩遍膩?zhàn)?，但用手指搓會掉粉，造成這種現(xiàn)象的原因有很多:
After scraping the putty twice, the powder will be removed when rubbing with fingers. There are many reasons for this phenomenon:
(1)施工中如使用不防水膩?zhàn)?如821膩?zhàn)?，不加膠或界面劑，出現(xiàn)上述情況并不奇怪。
(1) it is not surprising that no waterproof putty (such as 821 putty), no glue or interface agent are used in the construction.
(2)使用防水膩?zhàn)臃郏佔(zhàn)臃鄞嬖谫|(zhì)量問題。如:防水膩?zhàn)臃壑心z粉的含量較低，或防水膩?zhàn)臃塾糜诎姿唷⒒意}等膠結(jié)材料的質(zhì)量較差。
(2) the use of waterproof putty powder has quality problems. For example, the content of rubber powder in waterproof putty powder is low, or the quality of waterproof putty powder used in white cement, gray calcium and other cementitious materials is poor.
(3)現(xiàn)場配制膩?zhàn)臃?，采?08膠與滑石粉、重鈣粉直接混合，不添加水泥、灰鈣、石膏等無機(jī)膠凝材料，導(dǎo)致配制的膩?zhàn)臃蹚?qiáng)度低。
(3) the putty powder is prepared on site, which is directly mixed with 108 glue, talcum powder and heavy calcium powder, without adding cement, grey calcium, gypsum and other inorganic cementitious materials, resulting in low strength of putty powder.
(4)施工人員為了刮擦，將膩?zhàn)臃壅{(diào)配成低強(qiáng)度、柔軟的粉末。
(4) in order to scrape, the construction personnel will mix the putty powder into low strength and soft powder.
