濟南膩子粉脫粉根治：手搓實測！灰鈣添加≥200才是防脫底線

　　Jinan putty powder powder peeling cure: hand rubbing test! Adding gray calcium ≥ 200 is the bottom line for preventing detachment

　　墻面膩子脫粉，是建材行業和施工團隊非常頭疼的質量通病，也是影響膩子口碑和工程驗收的核心問題。膩子層干燥后輕輕一搓就掉粉、掉渣，后期刷漆、貼壁紙都會出現起皮、空鼓、脫落，返工成本出眾，很多人誤以為是施工干燥過快導致，實則核心原因是**灰鈣添加比例不足**，配方內膠凝材料含量不夠，膩子層內聚力缺失，才會出現頑固性脫粉。想要有效根治脫粉問題，沒有捷徑可走，合理把控灰鈣添加量，才是非常直接有效的解決辦法。

　　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.

　　灰鈣基膩子是濟南及北方地區常用的膩子品類，灰鈣作為核心膠凝成分，承擔著粘結成型、增強膩子層強度的關鍵作用，添加比例直接決定膩子是否脫粉、強度是否達標。市面上很多低價膩子為壓縮成本，刻意減少灰鈣添加量，看似原料成本降低，卻直接導致膩子層無強度、易脫粉，完全達不到施工標準。為了合理找到防脫粉的灰鈣添加底線，我們通過行業通用的手搓實測法，選取三組出彩具代表性的添加配比，做了對照實驗，數據結果直觀且有說服力。

　　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.

　　本次實驗選取100份、150份、200份三組灰鈣添加量，其余原料配比完全一致，添加等量清水調配，將三組膩子攪拌至完全相同的施工狀態，均勻批刮在三塊標準基層板上，待完全干燥固化后，用傳統手搓法檢測脫粉情況，這也是行業內非常直觀、非常實用的膩子強度檢測方式。實驗結果清晰呈現：灰鈣添加100份的樣板，輕輕用手一搓，大量粉末脫落，脫粉現象出彩其嚴重，膩子層完全無強度，屬于不合格產品；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，但依舊達不到施工驗收標準，后期依舊會出現掉粉問題。

　　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.

　　而灰鈣添加量達到200份的樣板，反復用手搓擦，表面完全無脫粉、無掉渣，膩子層緊實光滑，內聚力充足，強度完全達標，有效杜絕脫粉現象。這組實測數據充分證明，**灰鈣基膩子想要完全避免脫粉，灰鈣添加量非常低不能少于200份**，這是根治脫粉問題的硬性底線，低于這個比例，無論后期如何優化施工、調整干燥速度，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.

　　需要非常注意的是，我國不同地區生產的灰鈣，品質、有效成分含量存在差異，鈣粉純度、活性度各不相同，本次實驗數據僅作為通用配方參考。實際生產中，需根據當地采購灰鈣的實際品質，小幅微調添加比例，品質偏中下等的灰鈣，可適當提高添加量，確保膩子層強度達標；品質優良的高活性灰鈣，可在200份基礎上小幅浮動，但絕不能大幅降低標準，否則脫粉問題會再次出現。

　　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.

　　膩子脫粉看似小問題，實則關乎工程質量和產品口碑，無論是膩子生產廠家，還是施工團隊，都不能為了壓縮成本犧牲灰鈣添加比例。堅守200份灰鈣添加底線，配合優良的纖維素等助劑，才能打造出強度高、不脫粉、附著力強的優良膩子粉。根治脫粉沒有偏方，把控原料配比、守住核心添加量，才是非常靠譜的解決方案，也能有效省去后期返工的麻煩，保障墻面施工質量。

　　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.
