1、配料不同。外墻膩?zhàn)臃酆蛢?nèi)墻膩?zhàn)臃鄣闹饕獏^(qū)別就在于兩者之間的配料不同，由此造成的耐水性與硬度之間的區(qū)別。內(nèi)墻膩?zhàn)臃壑饕且噪p飛粉(大白粉)為主要原料，而外墻膩?zhàn)臃蹌t是以白水泥為主要原料，因此外墻膩?zhàn)臃鄣哪退院陀捕缺戎畠?nèi)墻膩?zhàn)臃蹃碚f要強(qiáng)上不少。

1. Different ingredients. The main difference between exterior wall putty powder and interior wall putty powder lies in the different ingredients between the two, resulting in differences in water resistance and hardness. The main raw material for interior wall putty powder is Shuangfei powder (large white powder), while the main raw material for exterior wall putty powder is white cement. Therefore, the water resistance and hardness of exterior wall putty powder are much stronger than those of interior wall putty powder.

2、性能不同。外墻膩?zhàn)臃凼且阅z粉材料為基料配以黏結(jié)材料及其他助劑精細(xì)加工而成。其突出的特點(diǎn)為黏結(jié)強(qiáng)度高耐水性、耐堿性、施工性能好。它作為室外建筑物表面找平材料可一勞永逸。避免了開裂、起泡、粉化及脫落等現(xiàn)象的發(fā)生。內(nèi)墻專用膩?zhàn)臃劬哂徐柟绦哉辰訌?qiáng)度、環(huán)保等特色。內(nèi)墻膩?zhàn)颖容^細(xì)膩。

2. Different performance. Exterior wall putty powder is finely processed using adhesive powder material as the base material, combined with bonding materials and other additives. Its outstanding characteristics are high bonding strength, water resistance, alkali resistance, and good construction performance. It can be used as a surface leveling material for outdoor buildings once and for all. Avoiding the occurrence of cracking, foaming, pulverization, and peeling. The special putty powder for interior walls has characteristics such as consolidating adhesive strength and environmental protection. The inner wall putty is relatively delicate.

3、環(huán)保性能。在環(huán)保方面，外墻膩?zhàn)臃酆蛢?nèi)墻膩?zhàn)臃蹆烧唛g也依然沒有太大區(qū)別，環(huán)保性能基本是相同的。由于外墻膩?zhàn)右挚癸L(fēng)吹日曬所以粘性大、強(qiáng)度高，但是環(huán)保指數(shù)就稍低。反之內(nèi)墻膩?zhàn)泳捅容^健康環(huán)保，所以內(nèi)墻不外用，外墻不內(nèi)用。

3. Environmental performance. In terms of environmental protection, there is still not much difference between exterior wall putty powder and interior wall putty powder, and their environmental performance is basically the same. Due to its resistance to wind and sun, the exterior wall putty has high viscosity and strength, but its environmental protection index is slightly lower. On the contrary, interior wall putty is more healthy and environmentally friendly, so interior walls are not used externally and exterior walls are not used internally.
