墻面裝修中，膩子粉如同看不見的 “幕后英雄”，雖不直接展現美感，卻決定著墻面的平整度、耐用性和后續涂料的附著效果。但市場上膩子粉種類繁多、質量良莠不齊，想要挑到一款優質產品，需要從原料、性能、使用體驗等多個維度層層篩選，才能讓墻面裝修少走彎路。

　　In wall decoration, putty powder is like an invisible "behind the scenes hero". Although it does not directly showcase beauty, it determines the flatness, durability, and adhesion effect of subsequent coatings on the wall. But there are many types of putty powders in the market, and the quality varies greatly. To find a high-quality product, it is necessary to screen from multiple dimensions such as raw materials, performance, and user experience, in order to avoid detours in wall decoration.

　　一、辨原料：探尋膩子粉的 “品質根基”

　　1、 Identifying raw materials: exploring the "quality foundation" of putty powder

　　膩子粉的核心性能，很大程度上取決于原料構成。優質膩子粉多以碳酸鈣、灰鈣粉等天然礦物為主要填料，這些原料純度高、顆粒細膩，能保證膩子的平整度和硬度。其中，重鈣粉（天然研磨碳酸鈣）環保性好，輕鈣粉（化學合成碳酸鈣）則具有更好的懸浮性和觸變性，兩者合理配比能提升膩子的施工性能。膠凝材料同樣關鍵，可再分散乳膠粉、纖維素醚等添加劑能增強膩子的粘結力和柔韌性，避免開裂；而劣質產品可能使用淀粉膠、聚乙烯醇等廉價膠水，不僅粘結性差，還易發霉、脫粉。選購時，可查看產品說明或向商家詢問原料成分，優先選擇標注清晰、采用優質添加劑的產品。

　　The core performance of putty powder largely depends on the composition of raw materials. High quality putty powder is mainly filled with natural minerals such as calcium carbonate and calcium ash powder. These raw materials have high purity and fine particles, which can ensure the flatness and hardness of putty. Among them, heavy calcium powder (natural ground calcium carbonate) has good environmental protection, while light calcium powder (chemically synthesized calcium carbonate) has better suspension and thixotropy. A reasonable ratio of the two can improve the construction performance of putty. Cementitious materials are equally crucial. Additives such as redispersible latex powder and cellulose ether can enhance the adhesion and flexibility of putty, avoiding cracking; Poor quality products may use cheap adhesives such as starch glue and polyvinyl alcohol, which not only have poor adhesion, but are also prone to mold and powdering. When making a purchase, you can check the product description or inquire about the ingredients from the merchant, and prioritize products with clear labeling and high-quality additives.

　　二、查指標：讀懂膩子粉的 “性能語言”

　　2、 Check indicators: understand the "performance language" of putty powder

　　判斷膩子粉質量，需關注幾個關鍵指標。首先是粘結強度，它直接影響膩子與墻面的結合牢固程度，高強度的膩子能有效防止起皮、脫落。根據國家標準，合格的耐水型膩子浸水后的粘結強度應≥0.5MPa，而非耐水型膩子在干燥環境下的粘結強度也需達標。其次是耐水性，耐水膩子在潮濕環境下不易粉化、發霉，適用于廚房、衛生間等區域；普通膩子則更適合干燥的室內空間。此外，環保性不容忽視，應選擇通過相關環保認證、甲醛釋放量低的產品，避免裝修污染。可要求商家提供產品檢測報告，核對各項指標是否符合標準。

　　To judge the quality of putty powder, several key indicators need to be considered. Firstly, the bonding strength directly affects the degree of adhesion between the putty and the wall. High strength putty can effectively prevent peeling and detachment. According to national standards, the bonding strength of qualified water-resistant putty after immersion in water should be ≥ 0.5MPa, while the bonding strength of non water-resistant putty in dry environments should also meet the standard. Next is water resistance. Water resistant putty is not easily powdery or moldy in humid environments and is suitable for areas such as kitchens and bathrooms; Ordinary putty is more suitable for dry indoor spaces. In addition, environmental friendliness cannot be ignored, and products that have passed relevant environmental certifications and have low formaldehyde emissions should be selected to avoid decoration pollution. Merchants can be required to provide product testing reports to verify whether various indicators meet the standards.

　　三、看外觀：捕捉膩子粉的 “細節信號”

　　3、 Look at appearance: Capture the "detail signal" of putty powder

　　從產品外觀也能初步判斷膩子粉的優劣。優質膩子粉包裝完整，標識清晰，注明產品名稱、執行標準、生產日期、保質期等信息；若包裝簡陋、信息不全，需謹慎選擇。打開包裝后，觀察粉料狀態：好的膩子粉色澤均勻，無結塊、雜質；若發現粉料發黃、結塊或有刺鼻氣味，說明原料可能受潮或添加劑質量不佳。此外，可將少量膩子粉加水攪拌，觀察其細膩度和粘稠度：細膩順滑、無顆粒感，且靜置后不易分層的產品，通常施工性能更好。

　　The quality of putty powder can also be preliminarily judged from the appearance of the product. High quality putty powder packaging is complete, with clear labeling indicating product name, implementation standards, production date, shelf life, and other information; If the packaging is simple and the information is incomplete, one should choose carefully. After opening the packaging, observe the state of the powder: good putty has a uniform pink color, without lumps or impurities; If the powder turns yellow, clumps or has a pungent odor, it indicates that the raw materials may be damp or the quality of the additives may be poor. In addition, a small amount of putty powder can be mixed with water to observe its fineness and viscosity: products that are delicate, smooth, without particle sensation, and are not easy to layer after standing are usually better in terms of construction performance.

　　四、試手感：體驗膩子粉的 “實操表現”

　　4、 Touch test: Experience the "practical performance" of putty powder

　　實際施工體驗是檢驗膩子粉好壞的重要環節。取適量膩子粉加水攪拌均勻，用刮刀刮涂在板材或墻面上，感受其順滑度和延展性。優質膩子粉施工流暢，易批刮，不會出現阻力大、拉毛等現象；刮涂后的表面平整光滑，無氣孔、裂紋。干燥后，用手輕擦膩子表面，若幾乎不掉粉，說明硬度和耐水性達標；若粉末明顯，或指甲輕劃即出現劃痕，則說明質量欠佳。此外，注意膩子的干燥速度，過快干燥可能導致開裂，過慢則影響施工進度，合適的干燥時間應與產品說明相符。

　　The actual construction experience is an important part of testing the quality of putty powder. Take an appropriate amount of putty powder and mix it evenly with water. Use a scraper to apply it to the board or wall, and feel its smoothness and ductility. High quality putty powder can be applied smoothly, easily scraped, and will not cause high resistance or roughness; The surface after scraping is smooth and flat, without pores or cracks. After drying, gently wipe the surface of the putty with your hand. If there is almost no powder falling off, it indicates that the hardness and water resistance meet the standards; If the powder is obvious or scratches appear when lightly scratched, it indicates poor quality. In addition, pay attention to the drying speed of putty. Drying too quickly may cause cracking, while drying too slowly may affect the construction progress. The appropriate drying time should be consistent with the product instructions.

　　五、比口碑：參考膩子粉的 “用戶反饋”

　　5、 Compared to word-of-mouth: Refer to the "user feedback" of putty powder

　　市場口碑和用戶評價是了解膩子粉真實質量的重要渠道。可向裝修工人、已完工的業主咨詢，了解不同產品的實際使用效果。例如，詢問某款膩子粉在施工過程中是否容易操作，干燥后墻面是否平整，長期使用有無開裂、脫落等問題。也可關注網絡裝修論壇、社群中的討論，收集多方意見，但需注意甄別信息真實性，避免被夸大或虛假評價誤導。同時，選擇有售后保障的商家，若使用過程中出現質量問題，能及時獲得解決方案。

　　Market reputation and user feedback are important channels for understanding the true quality of putty powder. You can consult with decoration workers and completed homeowners to understand the actual usage effects of different products. For example, inquire whether a certain putty powder is easy to operate during the construction process, whether the wall surface is flat after drying, and whether there are any issues such as cracking or peeling after long-term use. You can also pay attention to discussions on online decoration forums and communities, collect opinions from multiple parties, but be careful to verify the authenticity of the information and avoid being misled by exaggerated or false evaluations. At the same time, choosing merchants with after-sales support can provide timely solutions if quality problems occur during use.
