看包裝和標識

　　Check the packaging and labeling

　　優良抹灰找平石膏通常會有明確的生產廠家、生產日期、規格、等級等標識。在購買時，首先要查看產品的包裝是否完好，確認生產廠家和品牌。此外，還要查看產品的保質期，確保石膏沒有過期。

　　High quality plastering and leveling gypsum usually have clear markings such as manufacturer, production date, specifications, grade, etc. When purchasing, the first thing to check is whether the product packaging is intact and confirm the manufacturer and brand. In addition, it is necessary to check the shelf life of the product to ensure that the gypsum has not expired.

　　看顏色和質感

　　Look at color and texture

　　優良的抹灰找平石膏顏色呈白色或灰白色，質地細膩，無明顯顆粒。如果石膏顏色發黃、灰暗，或者有較多顆粒，說明質量可能較差。此外，優良石膏粉手感細膩，摸起來像面粉一樣，而質量不好的石膏則可能手感粗糙，甚至有刺手感。

　　High quality plastering and leveling gypsum has a white or grayish white color, a delicate texture, and no obvious particles. If the color of gypsum is yellow, dark, or there are many particles, it may indicate poor quality. In addition, high-quality gypsum powder has a delicate texture that feels like flour, while low-quality gypsum may have a rough or even prickly texture.

　　聞氣味優良抹灰找平石膏應該是無味的，或者氣味非常輕微。如果在購買時聞到刺鼻的氣味，說明石膏中可能添加了其他化學成分，這樣的石膏質量往往不佳。

　　High quality plastering and leveling gypsum should be odorless or have a very mild odor. If you smell a pungent odor when purchasing, it indicates that other chemical components may have been added to the gypsum, and the quality of such gypsum is often poor.

　　看施工性能

　　Check the construction performance

　　在施工過程中，優良抹灰找平石膏混合后的漿體應該易于施工，涂抹均勻，且干燥速度適中。如果漿體過于干硬或稀軟，不易施工，說明石膏質量可能不佳。

　　During the construction process, the high-quality plastering and leveling gypsum mixture should be easy to apply, evenly spread, and have a moderate drying speed. If the slurry is too dry or too soft to be easily applied, it indicates that the quality of gypsum may be poor.

　　看強度

　　Check the intensity

　　抹灰找平石膏的強度是衡量其質量的重要指標。在購買時，可以詢問銷售人員或查看產品說明，了解石膏的抗壓強度和抗折強度。優良石膏抗壓強度和抗折強度較高，能滿足正常的裝修需求。

　　The strength of plastering and leveling gypsum is an important indicator for measuring its quality. When purchasing, you can ask the salesperson or check the product description to understand the compressive strength and flexural strength of gypsum. High quality gypsum has high compressive strength and flexural strength, which can meet normal decoration needs.
