裝修選對膩子粉石膏粉才關鍵！選擇要點與核心標準全科普

　　Choosing the right putty powder and gypsum powder for decoration is the key! Select key points and core standards for comprehensive science popularization

　　很多業主裝修時總把重心放在乳膠漆上，覺得選對乳膠漆就能解決環保問題，卻忽略了用量更大、影響更深的膩子粉和石膏粉。要知道，一套120平的房子，乳膠漆無非1桶底漆、2桶面漆就夠了，但膩子粉和石膏粉的用量，一戶下來往往要四五十袋，多的甚至六七十袋——這么大的用量，一旦選到劣質產品，環保隱患會成倍累積，再好的乳膠漆也救不了后期甲醛超標的問題。作為專業膩子粉石膏粉生產廠家，今天就為大家科普這兩種材料的選擇要點，以及必須認準的核心標準，幫你避開裝修“隱形坑”。

　　Many homeowners tend to focus on latex paint when decorating, thinking that choosing the right latex paint can solve environmental problems, but they overlook the larger and more impactful use of putty powder and gypsum powder. You should know that for a 120 square meter house, only one bucket of primer and two buckets of topcoat are enough for latex paint. However, the amount of putty powder and gypsum powder used per household often requires forty to fifty bags, and even sixty to seventy bags. With such a large amount of usage, once inferior products are selected, environmental hazards will accumulate twice as much. Even the best latex paint cannot save the problem of excessive formaldehyde in the later stage. As a professional manufacturer of putty powder and gypsum powder, today we will explain the key points for selecting these two materials and the core standards that must be identified to help you avoid hidden pitfalls in decoration.

　　首先要明確，膩子粉和石膏粉之所以重要，不僅因為用量大，更因為它們是墻面的“基礎層”——后期會被乳膠漆覆蓋，一旦出現環保問題或質量問題，很難維修，要么將就住，要么砸掉重來，成本極高。所以選這兩種材料，不能只看價格，要從“品牌、標準、直觀品質”三個維度較真。

　　Firstly, it should be clarified that the importance of putty powder and gypsum powder is not only due to their large usage, but also because they are the "foundation layer" of the wall - they will be covered by latex paint in the later stage. Once there are environmental or quality issues, it is difficult to repair, either to settle for them or to smash them and start over, with extremely high costs. So when choosing these two materials, you can't just look at the price, you need to compare them from the three dimensions of "brand, standard, and intuitive quality".

　　選材料的第一步，是優先選正規品牌。這里的“品牌”不是指要選多高端的名字，而是要選有完整生產資質、明確廠家信息的正規產品，堅決避開“三無產品”——那些無品牌標識、無生產地址、無聯系方式的粉末，大概率是小作坊用劣質原料生產的，可能摻了不明添加劑，不僅甲醛、VOC容易超標，還可能因為雜質多、配比不均，導致墻面空鼓、開裂，后期維修特別麻煩。正規品牌的產品，會有清晰的包裝標識，生產流程和原料管控也更嚴格，環保和質量更有保障。

　　The first step in selecting materials is to prioritize choosing reputable brands. The term 'brand' here does not refer to choosing a high-end name, but rather to selecting legitimate products with complete production qualifications and clear manufacturer information, and resolutely avoiding 'three no products' - powders without brand identification, production address, and contact information, which are likely produced by small workshops using inferior raw materials and may contain unknown additives. Not only is formaldehyde and VOC easily exceeded, but it may also cause wall hollowing and cracking due to impurities and uneven proportions, making later maintenance particularly troublesome. Legitimate brand products have clear packaging labels, stricter production processes and raw material control, and better environmental protection and quality assurance.

　　核心中的核心，是認準執行標準——這是判斷材料是否合格的“硬指標”，不能只聽商家口頭承諾。

　　The core of the core is to identify the execution standards - this is the "hard indicator" to judge whether the materials are qualified, and cannot just rely on verbal promises from merchants.

　　對于膩子粉，要同時看“性能標準”和“環保標準”：性能上，需符合GB/T 28627-2012《建筑用墻面膩子》，這個標準把膩子粉分為普通型（P型）和耐水型（N型），普通型適合干燥地區的墻面，潮濕地區（比如南方梅雨區、衛生間周邊）一定要選耐水型，避免后期墻面受潮掉皮；環保上，必須符合GB 18582-2020《建筑用墻面涂料中有害物質限量》，重點看“甲醛釋放量”和“VOC含量”，國標要求甲醛釋放量≤0.1mg/m?（優質產品能做到“未檢出”），VOC含量≤100g/L，這兩項不達標，再便宜也不能買。

　　For putty powder, both "performance standards" and "environmental standards" should be considered simultaneously: in terms of performance, it needs to comply with GB/T 28627-2012 "Building Wall Putty", which divides putty powder into ordinary (P-type) and water-resistant (N-type) types. Ordinary types are suitable for walls in dry areas, while water-resistant types must be selected in humid areas (such as southern plum rain areas and around bathrooms) to avoid later wall peeling due to moisture; In terms of environmental protection, it must comply with GB 18582-2020 "Limits of Hazardous Substances in Building Wall Coatings", with a focus on "formaldehyde emission" and "VOC content". The national standard requires formaldehyde emission to be ≤ 0.1mg/m? High quality products can achieve "undetectable" and VOC content ≤ 100g/L. These two items do not meet the standards, and no matter how cheap they are, they cannot be bought.

　　對于石膏粉（比如粉刷石膏、嵌縫石膏），標準則要區分類型：粉刷石膏是墻面找平的主力，需符合JC/T 517-2017《粉刷石膏》，這個標準對石膏粉的強度、凝結時間、保水性有明確要求——比如初凝時間要≥60分鐘（給施工留足時間），終凝時間≤120分鐘（不耽誤后續工序），保水性差的石膏粉容易干得快，墻面會出現裂紋；嵌縫石膏用來補縫隙，要符合JC/T 2075-2021《嵌縫石膏》，重點看粘結強度和收縮率，收縮率高的嵌縫石膏，補完縫隙后容易開裂，影響墻面美觀。而且不管哪種石膏粉，環保上都要符合GB 18582-2020，確保無甲醛、低VOC。

　　For gypsum powder (such as plastering gypsum and joint filling gypsum), the standard should distinguish the types: plastering gypsum is the main force for wall leveling and needs to comply with JC/T 517-2017 "Plastering Gypsum". This standard has clear requirements for the strength, setting time, and water retention of gypsum powder - for example, the initial setting time should be ≥ 60 minutes (leaving enough time for construction), and the final setting time should be ≤ 120 minutes (not delaying subsequent processes). Gypsum powder with poor water retention is prone to dry quickly and cracks may appear on the wall surface; Jointing gypsum is used to fill gaps and must comply with JC/T 2075-2021 "Jointing Gypsum", with a focus on bonding strength and shrinkage rate. Jointing gypsum with high shrinkage rate is prone to cracking after filling gaps, which affects the appearance of the wall. And regardless of the type of gypsum powder, it must comply with GB 18582-2020 in terms of environmental protection, ensuring no formaldehyde and low VOC.

　　除了看品牌和標準，還有幾個直觀判斷小技巧能幫你快速篩選：看包裝，優質產品的包裝上會清晰印著執行標準號、生產日期、廠家電話，信息不全的要謹慎；打開包裝后看粉末狀態，好的膩子粉和石膏粉應該細膩無結塊、顏色均勻（膩子粉多為純凈白色，石膏粉偏淺灰或奶白色），有結塊說明受潮或儲存不當，質量會打折扣；如果能取樣，抓一把粉末捻一捻，手感細膩無顆粒感的更好，粗糙的可能雜質多，會影響施工時的順滑度和墻面最終的平整度。

　　In addition to looking at the brand and standards, there are several intuitive judgment tips that can help you quickly screen: Look at the packaging. High quality products will have the execution standard number, production date, and manufacturer's phone number clearly printed on the packaging. Be cautious if the information is incomplete; After opening the packaging, check the powder status. Good putty powder and gypsum powder should be delicate, free of lumps, and have uniform color (putty powder is mostly pure white, gypsum powder tends to be light gray or milky white). If there are lumps, it indicates moisture or improper storage, and the quality will be compromised; If it is possible to take samples, grab a handful of powder and twist it one by one. It feels fine and has no graininess, which is better. Rough surfaces may have more impurities, which will affect the smoothness of construction and the final flatness of the wall.

　　廠家給業主的實用建議

　　Practical advice from manufacturers to homeowners

　　作為生產廠家，我們每次生產都會嚴格按照上述標準把控，每批次產品都要做甲醛、VOC檢測，確保達標后才出廠。但業主自己選購時，一定要“主動要檢測報告”——讓商家提供近一年內的第三方檢測報告，重點核對“甲醛釋放量”“VOC含量”是否符合國標，不要相信“口頭環保”；另外，別圖便宜買低價產品，看似省了幾十塊，后期要是甲醛超標或墻面開裂，重新鏟墻、重做的成本會高得多，反而得不償失。

　　As a manufacturer, we strictly control our production according to the above standards. Each batch of products must undergo formaldehyde and VOC testing to ensure compliance before leaving the factory. But when homeowners make their own purchases, they must "actively request a testing report" - ask the merchant to provide a third-party testing report within the past year, focusing on checking whether the "formaldehyde emission" and "VOC content" meet the national standards, and not believe in "verbal environmental protection"; In addition, don't try to buy low-priced products at a low price. It may seem like you've saved a few dozen yuan, but if the formaldehyde exceeds the standard or the wall cracks in the later stage, the cost of redoing the wall will be much higher, which is not worth the loss.
