查環保性能：膩子粉的環保性能直接關系到室內空氣質量和人體健康。優先選擇通過國家環保標準認證的產品，如符合 GB 18582-2020《建筑用墻面涂料中有害物質限量》標準的膩子粉。此外，還可以查看產品是否有十環認證等權威環保認證標志，盡量選擇低甲醛、低 VOC 含量的膩子粉。

Check environmental performance: The environmental performance of putty powder is directly related to indoor air quality and human health. Priority should be given to products certified by national environmental standards, such as putty powder that meets the GB 18582-2020 "Limits of Hazardous Substances in Building Wall Coatings" standard. In addition, you can also check whether the product has authoritative environmental certification marks such as the Ten Ring Certification, and try to choose putty powder with low formaldehyde and low VOC content.

試手感：優質的膩子粉手感細膩，用手觸摸時不會有顆粒感或粗糙感。可以取少量膩子粉放在手指間揉搓，感受其細膩程度。如果膩子粉顆粒較大，可能會影響施工效果和墻面的平整度。

Touch sensation: High quality putty powder has a delicate touch, and there will be no graininess or roughness when touched by hand. You can take a small amount of putty powder and rub it between your fingers to feel its delicacy. If the particles of putty powder are large, it may affect the construction effect and the flatness of the wall.

看白度：膩子粉的白度也是一個重要的指標，一般來說，白度越高，墻面的裝飾效果越好。在選擇時，可以將不同品牌的膩子粉放在一起進行對比，觀察其白度。但需要注意的是，白度并不是唯一的衡量標準，不能僅僅因為白度高就選擇某一款膩子粉，還需要綜合考慮其他性能。

Whiteness: The whiteness of putty powder is also an important indicator. Generally speaking, the higher the whiteness, the better the decorative effect of the wall. When choosing, different brands of putty powder can be compared together to observe their whiteness. However, it should be noted that whiteness is not the only measure, and one should not choose a certain putty powder just because of its high whiteness. Other properties also need to be considered comprehensively.

測粘結強度：膩子粉的粘結強度直接影響到墻面的使用壽命和質量。可以通過簡單的測試方法來評估其粘結強度，如將膩子粉涂抹在小塊木板或墻面上，待其干燥后，用手或工具輕輕刮擦，觀察膩子粉是否容易脫落。如果膩子粉能夠牢固地附著在基層上，不易脫落，說明其粘結強度較好。

Testing bond strength: The bond strength of putty powder directly affects the service life and quality of the wall. The bonding strength can be evaluated through simple testing methods, such as applying putty powder on small wooden boards or walls, waiting for them to dry, gently scraping with hands or tools, and observing whether the putty powder is easy to peel off. If the putty powder can firmly adhere to the base layer and is not easy to fall off, it indicates that its bonding strength is good.

了解施工性能：好的膩子粉施工性能良好，容易批刮，干燥速度適中，且在干燥后不易出現開裂、空鼓等問題。可以向商家咨詢膩子粉的施工要求和注意事項，了解其施工性能。此外，也可以參考其他用戶的使用評價和施工經驗，選擇施工性能好的膩子粉。

Understanding construction performance: Good putty powder has good construction performance, is easy to scrape, has a moderate drying speed, and is not prone to cracking, hollowing, and other problems after drying. You can consult with merchants about the construction requirements and precautions of putty powder to understand its construction performance. In addition, you can also refer to the usage evaluation and construction experience of other users to choose putty powder with good construction performance.

考慮價格：膩子粉的價格因品牌、質量、性能等因素而異。在選擇時，不要盲目追求低價產品，也不要認為價格高的產品就一定是最好的。要根據自己的實際需求和預算，選擇性價比高的膩子粉。一般來說，質量較好的膩子粉價格相對較高，但從長期來看，能夠為你節省維修和返工的成本。

Considering price: The price of putty powder varies depending on factors such as brand, quality, and performance. When choosing, do not blindly pursue low-priced products, and do not assume that products with high prices are necessarily the best. Choose a cost-effective putty powder based on your actual needs and budget. Generally speaking, high-quality putty powder has a relatively high price, but in the long run, it can save you maintenance and rework costs.
