How to choose putty powder

（1）膩子粉的構成

(1) Composition of putty powder

膩子粉主要由水泥、膠粉、灰鈣粉、保水劑、纖維等組成。

Putty powder is mainly composed of cement, rubber powder, lime calcium powder, water retaining agent, fiber, etc.

水泥和膠粉是膩子中更為關鍵的部分，起到粘結的作用；

Cement and rubber powder are the key parts of putty and play the role of bonding;

灰鈣起到填充的作用；

Gray calcium plays the role of filling;

保水劑起到保水、貯存和施工性能的作用；

Water retaining agent plays the role of water retention, storage and construction performance;

纖維起到了抗開裂的作用；

The fiber plays the role of anti cracking;

（2）膩子粉的種類

(2) Types of putty powder

市面上的膩子粉主要分為普通膩子和耐水膩子，建議選擇耐水膩子！

The putty powder on the market is mainly divided into ordinary putty and water-resistant putty. It is recommended to choose water-resistant putty!

強度；耐水膩子在粘結強度在標準狀態粘結強度達到0.50Mpa以上，而普通型僅為0.30Mpa以上；

strength; The bonding strength of water-resistant putty is in the standard state, and the bonding strength is more than 0.50mpa, while that of ordinary putty is only more than 0.30mpa;

使用壽命；耐水膩子在水中侵泡48小時仍然不會起皮、開裂脫落，使用壽命達到10年以上；而普通型的侵泡后就會脫落，使用壽命3~5年。

service life; The waterproof putty will not peel, crack and fall off after soaking in water for 48 hours, and its service life will reach more than 10 years; The ordinary type will fall off after bubble invasion, with a service life of 3 ~ 5 years.

環保；耐水膩子粘結力高于一般膩子，所以批刮時不用添加膠水，更環保。

environment protection The adhesion of water-resistant putty is higher than that of ordinary putty, so there is no need to add glue during scraping, which is more environmentally friendly.

成本；耐水膩子的比普通膩子更貴，價格相差1~2倍，硬度較高，打磨的會更費力，工期更長些，所以綜合成本也會高一些。裝修時可以搭配著來使用，比如天花板就可以使用一般膩子。

Cost; Water resistant putty is more expensive than ordinary putty. The price difference is 1 ~ 2 times, the hardness is higher, the polishing will be more laborious, and the construction period will be longer, so the comprehensive cost will be higher. When decorating, it can be used together. For example, general putty can be used for the ceiling.

綜合上述，耐水膩子在家裝中性能表現的更優異，特別適用于南方或延江延海容易潮濕進水的地方，無特殊情況，都應該選擇耐水膩子。

Based on the above, the performance of water-resistant putty is better in home decoration. It is especially suitable for places in the South or Yanjiang Yanhai where water is easy to enter. Water resistant putty should be selected without special circumstances.

（3）看環保性

(3) Look at environmental protection

在選購乳膠漆時，大家特別注重環保性能。而選擇膩子粉卻沒那么重視，而膩子粉的用量要比乳膠漆的用量多的多。

When purchasing latex paint, we pay special attention to environmental protection performance. The choice of putty powder is not so important, and the amount of putty powder is much more than that of emulsion paint.
