抗裂砂浆与抹面砂浆的区别主要体现在以下五个方面：

　　The difference between crack resistant mortar and plastering mortar is mainly reflected in the following five aspects:

　　一、用途差异

　　1、 Differences in usage

　　抗裂砂浆 ：专门用于保温板（如聚苯颗粒、玻化微珠）等柔性材料的表面抹灰层，通过增强抗裂性能保护墙体免受变形开裂。

　　Crack resistant mortar: specifically used as a surface plaster layer for flexible materials such as insulation boards (such as polystyrene particles, vitrified microbeads), to enhance crack resistance and protect walls from deformation and cracking.

　　抹面砂浆 ：用于建筑物内外墙表面及基底材料的保护层，兼具粘结基层、防脱落和美观功能。

　　Plastering mortar: used as a protective layer for the surface and base materials of interior and exterior walls of buildings, with the functions of bonding base, preventing detachment, and aesthetic appeal.

　　二、成本与性能

　　2、 Cost and Performance

　　成本 ：抹面砂浆因工艺要求高（如需薄层施工、破板率控制），成本显著高于抗裂砂浆。

　　Cost: The cost of plastering mortar is significantly higher than that of crack resistant mortar due to high process requirements (such as thin layer construction and control of board breakage rate).

　　柔性 ：抹面砂浆需适应保温板等材料的变形，柔性要求更高；抗裂砂浆虽抗裂性能突出，但柔性相对较差。

　　Flexibility: The plastering mortar needs to adapt to the deformation of insulation boards and other materials, with higher flexibility requirements; Although crack resistant mortar has outstanding crack resistance, its flexibility is relatively poor.

　　三、厚度与施工

　　3、 Thickness and Construction

　　厚度 ：抗裂砂浆需较厚（通常-厘米），以提供充分保护；抹面砂浆为薄层（0.3-0.5厘米），需分层施工达到平整光洁的效果。

　　Thickness: The anti cracking mortar needs to be relatively thick (usually - centimeters) to provide sufficient protection; The plastering mortar is a thin layer (0.3-0.5 cm), which needs to be constructed layer by layer to achieve a smooth and polished effect.

　　施工要求 ：抗裂砂浆对基层处理要求严格，需防止水冲；抹面砂浆更注重表面细腻度，便于装饰。

　　Construction requirements: Crack resistant mortar requires strict treatment of the base layer and must prevent water flushing; The plastering mortar pays more attention to the surface delicacy, which is convenient for decoration.

　　四、材料与成分

　　4、 Materials and Components

　　抗裂砂浆 ：含聚合物乳液、抗裂剂（如硅灰）及水泥，通过填充孔隙和增强粘结性实现抗裂。

　　Anti crack mortar: containing polymer lotion, anti crack agent (such as silica fume) and cement, it can achieve anti crack by filling the pores and enhancing the cohesiveness.

　　抹面砂浆 ：以水泥、砂为主，部分配方添加防水剂或隔音材料，满足耐水、耐久等需求。

　　Mortar for plastering: mainly composed of cement and sand, with some formulations adding waterproofing agents or sound insulation materials to meet water resistance, durability and other requirements.

　　五、适用场景

　　5、 Applicable scenarios

　　抗裂砂浆 ：多用于外墙保温系统、防裂工程等对防裂性能要求高的场景。

　　Crack resistant mortar: commonly used in exterior wall insulation systems, crack prevention projects, and other scenarios that require high crack resistance performance.

　　抹面砂浆 ：适用于干燥环境下的内外墙装饰、地面找平及基底层保护。

　　Plastering mortar: suitable for interior and exterior wall decoration, ground leveling, and base layer protection in dry environments.
