腻子粉的使用标准涉及多个方面，包括执行标准、环保性能、粘结强度、施工性能等。以下是详细的使用标准：

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:

执行标准：

Execution standards:

腻子粉应符合国家标准《JG/T 298-2010（Y/N）建筑室内用腻子》，其中“Y”表示普通型腻子，“N”表示耐水型腻子。

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.

内墙腻子粉还应符合GB 18582-2008《室内装饰装修材料 内墙涂料中有害物质限量标准》。

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".

环保性能：

Environmental performance:

腻子粉应符合GB 18582-2020《建筑用墙面涂料中有害物质限量》的要求，确保无VOC、甲醛、总铅、可溶性重金属（汞、铬、镉等）等有害物质。

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.).

环保标准还包括JG/T157-2009《建筑外墙用腻子》。

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

粘结强度：

Adhesive strength:

普通腻子的标准状态粘结强度应不低于0.3 MPa，耐水腻子的标准状态粘结强度应不低于0.5 MPa，浸水后的粘结强度也不应低于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.

建筑外墙用腻子粉的粘结强度要求更高，标准状态下的粘结强度应≥0.60MPa，冻融循环后的粘结强度应大于等于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:

容器中状态要求无结块、均匀，施工性要求刮涂无障碍。

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

干燥时间（表干）应≤5小时，吸水量≤2.0g/10min，耐碱性和耐水性要求无异常。

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.

施工温度应在5℃以上，腻子粉调成膏状后应在4-5小时内使用，避免变质。

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.

其他注意事项：

Other precautions:

基层处理：确保基层坚实、干净、平整，吸水性强的基层需先润湿或封底处理。

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之间，总厚度不宜超过3mm。

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

贮存条件：腻子粉应存放在通风干燥阴凉处，防止受潮，保质期通常为6到12个月。

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.

通过以上标准，可以确保腻子粉的质量和施工效果，满足建筑装饰的需求。

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