　　The peeling off of wall putty is the most common quality problem in the building materials industry and construction teams, and it is also the core issue affecting the reputation and engineering acceptance of putty. After the putty layer is dried, it will fall off powder and debris with a gentle rub. In the later stage of painting and wallpaper pasting, peeling, hollowing, and falling off will occur. The cost of rework is extremely high, and many people mistakenly believe that it is caused by too fast drying during construction. In fact, the core reason is the insufficient proportion of calcium ash added, the insufficient content of cementitious materials in the formula, and the lack of cohesion in the putty layer, which leads to stubborn powder peeling. There is no shortcut to completely cure the problem of powdering. Accurately controlling the amount of calcium added is the most direct and effective solution.

　　Grey calcium based putty is a commonly used type of putty in Jinan and northern regions. Grey calcium serves as the core adhesive component and plays a key role in bonding and enhancing the strength of the putty layer. The addition ratio directly determines whether the putty will peel off and whether the strength meets the standard. Many low-priced putty products on the market intentionally reduce the amount of calcium added to reduce costs, which may seem like a decrease in raw material costs, but directly results in the putty layer having no strength and being prone to powder detachment, completely failing to meet construction standards. In order to accurately find the bottom line of anti powder gray calcium addition, we selected three highly representative addition ratios through the industry's commonly used hand rubbing measurement method and conducted a control experiment. The data results were intuitive and convincing.

　　本次實(shí)驗(yàn)選取100份、150份、200份三組灰鈣添加量，其余原料配比完全一致，添加等量清水調(diào)配，將三組膩?zhàn)訑嚢柚镣耆嗤氖┕顟B(tài)，均勻批刮在三塊標(biāo)準(zhǔn)基層板上，待完全干燥固化后，用傳統(tǒng)手搓法檢測(cè)脫粉情況，這也是行業(yè)內(nèi)最直觀、最實(shí)用的膩?zhàn)訌?qiáng)度檢測(cè)方式。實(shí)驗(yàn)結(jié)果清晰呈現(xiàn)：灰鈣添加100份的樣板，輕輕用手一搓，大量粉末脫落，脫粉現(xiàn)象極其嚴(yán)重，膩?zhàn)訉油耆珶o強(qiáng)度，屬于不合格產(chǎn)品；灰鈣添加150份的樣板，手搓后仍有明顯輕微脫粉，雖比100份配比有所改善，但依舊達(dá)不到施工驗(yàn)收標(biāo)準(zhǔn)，后期依舊會(huì)出現(xiàn)掉粉問題。

　　In this experiment, three sets of lime calcium addition amounts were selected: 100 parts, 150 parts, and 200 parts. The remaining raw material ratios were exactly the same, and an equal amount of water was added to mix the three sets of putty. The three sets of putty were stirred to the same construction state and evenly scraped onto three standard base boards. After complete drying and solidification, the traditional hand rubbing method was used to detect powder removal, which is also the most intuitive and practical putty strength testing method in the industry. The experimental results are clearly presented: a sample with 100 parts of gray calcium added, gently rubbed by hand, a large amount of powder falls off, and the phenomenon of powder detachment is extremely serious. The putty layer has no strength at all, which is an unqualified product; The sample with 150 parts of gray calcium added still showed obvious slight powder loss after hand rubbing. Although it improved compared to the 100 part ratio, it still did not meet the construction acceptance standards, and powder loss problems may still occur in the later stage.

　　而灰鈣添加量達(dá)到200份的樣板，反復(fù)用手搓擦，表面完全無脫粉、無掉渣，膩?zhàn)訉泳o實(shí)光滑，內(nèi)聚力充足，強(qiáng)度完全達(dá)標(biāo)，徹底杜絕脫粉現(xiàn)象。這組實(shí)測(cè)數(shù)據(jù)充分證明，**灰鈣基膩?zhàn)酉胍耆苊饷摲郏意}添加量最低不能少于200份**，這是根治脫粉問題的硬性底線，低于這個(gè)比例，無論后期如何優(yōu)化施工、調(diào)整干燥速度，都無法從根源解決脫粉難題。

　　The sample with a calcium ash addition of 200 parts can be repeatedly rubbed and wiped by hand, and the surface is completely free of powder and slag. The putty layer is compact and smooth, with sufficient cohesion and strength that meets the standard, completely eliminating the phenomenon of powder peeling. This set of actual test data fully proves that in order to completely avoid powdering, the minimum amount of lime calcium added for * * calcium based putty should not be less than 200 parts * *. This is the hard bottom line for curing powdering problems. Below this ratio, no matter how to optimize construction and adjust drying speed in the later stage, it is impossible to solve the problem of powdering from the root.

　　需要特別注意的是，我國(guó)不同地區(qū)生產(chǎn)的灰鈣，品質(zhì)、有效成分含量存在差異，鈣粉純度、活性度各不相同，本次實(shí)驗(yàn)數(shù)據(jù)僅作為通用配方參考。實(shí)際生產(chǎn)中，需根據(jù)當(dāng)?shù)夭少?gòu)灰鈣的實(shí)際品質(zhì)，小幅微調(diào)添加比例，品質(zhì)偏中下等的灰鈣，可適當(dāng)提高添加量，確保膩?zhàn)訉訌?qiáng)度達(dá)標(biāo)；品質(zhì)優(yōu)質(zhì)的高活性灰鈣，可在200份基礎(chǔ)上小幅浮動(dòng)，但絕不能大幅降低標(biāo)準(zhǔn)，否則脫粉問題會(huì)再次出現(xiàn)。

　　It should be noted that the quality and active ingredient content of gray calcium produced in different regions of China vary, and the purity and activity of calcium powder also differ. The data from this experiment is only used as a reference for general formulas. In actual production, it is necessary to slightly adjust the addition ratio based on the actual quality of locally purchased calcium ash. For calcium ash with lower quality, the addition amount can be appropriately increased to ensure that the strength of the putty layer meets the standard; High quality and high activity gray calcium can fluctuate slightly on the basis of 200 parts, but the standard must not be significantly lowered, otherwise the problem of powdering will occur again.

　　膩?zhàn)用摲劭此菩栴}，實(shí)則關(guān)乎工程質(zhì)量和產(chǎn)品口碑，無論是膩?zhàn)由a(chǎn)廠家，還是施工團(tuán)隊(duì)，都不能為了壓縮成本犧牲灰鈣添加比例。堅(jiān)守200份灰鈣添加底線，配合優(yōu)質(zhì)的纖維素等助劑，才能打造出強(qiáng)度高、不脫粉、附著力強(qiáng)的優(yōu)質(zhì)膩?zhàn)臃邸８蚊摲蹧]有偏方，把控原料配比、守住核心添加量，才是最靠譜的解決方案，也能徹底省去后期返工的麻煩，保障墻面施工質(zhì)量。

　　The detachment of putty powder may seem like a minor issue, but it is actually related to the quality of the project and the reputation of the product. Both putty manufacturers and construction teams cannot sacrifice the proportion of lime and calcium added in order to reduce costs. Adhering to the bottom line of adding 200 parts of calcium ash, combined with high-quality additives such as cellulose, can create high-quality putty powder with high strength, no powdering, and strong adhesion. There is no one size fits all solution for curing powdering. Controlling the ratio of raw materials and maintaining the core addition amount is the most reliable solution, which can completely save the trouble of rework in the later stage and ensure the quality of wall construction.
