　　Putty powder is divided into exterior wall putty powder and interior wall putty powder. Why is exterior wall putty powder not suitable for interior walls?

　　外墻膩?zhàn)右挚癸L(fēng)吹日曬所以膠性大、強(qiáng)度高，環(huán)保指數(shù)稍低。內(nèi)墻膩?zhàn)泳C合指數(shù)較好，健康環(huán)保，所以?xún)?nèi)墻膩?zhàn)臃鄄煌庥茫鈮δ佔(zhàn)臃鄄粌?nèi)用。

　　Exterior wall putty needs to resist wind and sun exposure, so it has high adhesive properties, high strength, and slightly lower environmental protection index. The comprehensive index of interior wall putty is good, which is healthy and environmentally friendly, so the interior wall putty powder should not be used externally, and the exterior wall putty powder should not be used internally.

　　歸根結(jié)底這都是由于內(nèi)墻與外墻有所區(qū)別：

　　Ultimately, this is all due to the difference between the interior and exterior walls:

　　1、含堿量不同

　　1. Different alkaline content

　　總的來(lái)說(shuō)外墻膩?zhàn)臃鄣暮瑝A量要高于內(nèi)墻膩?zhàn)臃邸?/p>

　　Overall, the alkali content of exterior wall putty powder is higher than that of interior wall putty powder.

　　2、施工難易和價(jià)格不同

　　2. Construction difficulty and price differences

　　外墻膩?zhàn)拥氖┕るy度要比內(nèi)墻膩?zhàn)拥氖┕るy度大的多，而通常來(lái)說(shuō)外墻膩?zhàn)觾r(jià)格要貴于內(nèi)墻膩?zhàn)印?/p>

　　The construction difficulty of exterior wall putty is much greater than that of interior wall putty, and generally speaking, the price of exterior wall putty is higher than that of interior wall putty.

　　3、環(huán)保性不同

　　3. Different environmental friendliness

　　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?xún)?nèi)墻不外用，外墻不內(nèi)用。

　　Due to the need to resist wind and sun exposure, exterior wall putty has high viscosity and strength, but its environmental protection index is slightly lower. On the contrary, putty for interior walls is healthier and more environmentally friendly, so interior walls should not be used externally and exterior walls should not be used internally.

　　4、性能不同

　　4. Different performance

　　內(nèi)墻膩?zhàn)颖容^細(xì)膩，所以主要一遇到水就會(huì)出現(xiàn)空鼓現(xiàn)象甚至脫落;而外墻膩?zhàn)泳捅容^粗糙，但是防水性能很好。

　　The putty on the interior wall is relatively delicate, so it will mainly appear hollow or even peel off when it comes into contact with water; The exterior wall putty is relatively rough, but it has good waterproof performance.

　　5、成分和耐水性不同

　　5. Different components and water resistance

　　由于兩種膩?zhàn)臃鄣呐浞讲煌鈮δ佔(zhàn)臃垡园姿酁橹鳎鴥?nèi)墻膩?zhàn)臃蹌t是以滑石粉、老粉為主。因此前者耐水性和硬度都比較強(qiáng)，哪怕遇水也不會(huì)出現(xiàn)軟化的現(xiàn)象;而后者的耐水性和強(qiáng)度相對(duì)外墻膩?zhàn)臃劬捅容^差，而且只要用指甲輕輕一刮就能夠刮出痕跡，遇到水也會(huì)出現(xiàn)軟化的現(xiàn)象。

　　Due to the different formulas of the two putty powders, the exterior wall putty powder is mainly made of white cement, while the interior wall putty powder is mainly made of talcum powder and old powder. Therefore, the former has strong water resistance and hardness, and will not soften even when exposed to water; The water resistance and strength of the latter are relatively poor compared to exterior wall putty powder, and as long as a nail is lightly scraped, it can leave a mark, and it will also soften when exposed to water.
