膩子粉的使用標準涉及多個方面，包括執行標準、環保性能、粘結強度、施工性能等。以下是詳細的使用標準：

The use standards of putty powder involve multiple aspects, including execution standards, environmental performance, bonding strength, construction performance, etc. The following are detailed usage standards:

執行標準：

Execution standards:

膩子粉應符合國家標準《JG/T 298-2010（Y/N）建筑室內用膩子》，其中“Y”表示普通型膩子，“N”表示耐水型膩子。

Putty powder should comply with the national standard JG/T 298-2010 (Y/N) Putty for Interior Use in Buildings, where "Y" represents ordinary putty and "N" represents water-resistant putty.

內墻膩子粉還應符合GB 18582-2008《室內裝飾裝修材料 內墻涂料中有害物質限量標準》。

The putty powder for interior walls should also comply with the GB 18582-2008 "Limit Standards for Harmful Substances in Interior Wall Coatings for Interior Decoration Materials".

環保性能：

Environmental performance:

膩子粉應符合GB 18582-2020《建筑用墻面涂料中有害物質限量》的要求，確保無VOC、甲醛、總鉛、可溶性重金屬（汞、鉻、鎘等）等有害物質。

Putty powder should comply with the requirements of GB 18582-2020 "Limits of Hazardous Substances in Building Wall Coatings", ensuring the absence of harmful substances such as VOCs, formaldehyde, total lead, soluble heavy metals (mercury, chromium, cadmium, etc.).

環保標準還包括JG/T157-2009《建筑外墻用膩子》。

The environmental standards also include JG/T157-2009 "Putty for Exterior Walls of Buildings".

粘結強度：

Adhesive strength:

普通膩子的標準狀態粘結強度應不低于0.3 MPa，耐水膩子的標準狀態粘結強度應不低于0.5 MPa，浸水后的粘結強度也不應低于0.3 MPa。

The standard bonding strength of ordinary putty should not be less than 0.3 MPa, the standard bonding strength of water-resistant putty should not be less than 0.5 MPa, and the bonding strength after immersion should not be less than 0.3 MPa.

建筑外墻用膩子粉的粘結強度要求更高，標準狀態下的粘結強度應≥0.60MPa，凍融循環后的粘結強度應大于等于0.40MPa。

The bonding strength requirements for putty powder used on building exterior walls are higher. The bonding strength under standard conditions should be ≥ 0.60MPa, and the bonding strength after freeze-thaw cycles should be greater than or equal to 0.40MPa.

施工性能：

Construction performance:

容器中狀態要求無結塊、均勻，施工性要求刮涂無障礙。

The state of the container requires no clumping and uniformity, and the workability requires smooth scraping and coating.

干燥時間（表干）應≤5小時，吸水量≤2.0g/10min，耐堿性和耐水性要求無異常。

The drying time (surface drying) should be ≤ 5 hours, the water absorption should be ≤ 2.0g/10min, and there should be no abnormalities in alkali resistance and water resistance requirements.

施工溫度應在5℃以上，膩子粉調成膏狀后應在4-5小時內使用，避免變質。

The construction temperature should be above 5 ℃, and the putty powder should be used within 4-5 hours after being mixed into a paste to avoid deterioration.

其他注意事項：

Other precautions:

基層處理：確保基層堅實、干凈、平整，吸水性強的基層需先潤濕或封底處理。

Grassroots treatment: Ensure that the base is solid, clean, and flat, and the base with strong water absorption needs to be wetted or sealed first.

批刮厚度：每次批刮厚度宜在0.8到1.5mm之間，總厚度不宜超過3mm。

Scratching thickness: The thickness of each scraping should be between 0.8 and 1.5mm, and the total thickness should not exceed 3mm.

貯存條件：膩子粉應存放在通風干燥陰涼處，防止受潮，保質期通常為6到12個月。

Storage conditions: Putty powder should be stored in a ventilated, dry, and cool place to prevent moisture. The shelf life is usually 6 to 12 months.

通過以上標準，可以確保膩子粉的質量和施工效果，滿足建筑裝飾的需求。

Through the above standards, the quality and construction effect of putty powder can be ensured, meeting the needs of building decoration.
