最近呢我們給幾個工地調了調普通抹面砂漿，這幾個工地的問題比較統一，都是抹面砂漿粘刀，我們總結了幾點引起粘刀的原因，全是干貨，記得點贊收藏。

　　Recently, we have adjusted ordinary plastering mortar for several construction sites. The problem with these sites is relatively uniform, which is the sticking of plastering mortar to the knife. We have summarized several reasons that cause knife sticking, all of which are dry goods. Remember to like and collect them.

　　第一，沙子級配不合理。沙子級配出現斷檔，本身良好的級配是細沙填充粗沙空隙，膠材漿料填充細沙空隙，一旦級配不合理，就容易造成手感重。

　　Firstly, the sand grading is unreasonable. There is a gap in sand grading, and a good grading is filled with fine sand to fill the gaps in coarse sand, and filled with adhesive slurry to fill the gaps in fine sand. Once the grading is unreasonable, it is easy to cause a heavy hand feel.

　　第二，沙子含泥量高，砂漿石粉含量高。老師傅以前抹墻的時候經常說打稠了加水，打稀了加粉，但是石粉比表面積很大，吸附的水很多，但又沒有活性，這就會導致砂漿很稠，而且還沒有強度，所以保持合理比例的粉料至關重要。

　　Secondly, sand has a high mud content and mortar has a high content of stone powder. When the old master used to plaster walls, he often said to add water when it was thick and powder when it was thin. However, the specific surface area of stone powder is large, and it adsorbs a lot of water, but it is not active. This can cause the mortar to be thick and weak, so it is crucial to maintain a reasonable proportion of powder.

　　第三，容重高。有些人認為引氣劑百害而無一利，所以他們對引氣劑極為排斥，如果不加引氣劑，就會導致抹面砂漿容重高，手感重，不易批刮。其實引氣劑是萬金油，極低摻量就能有效改變施工手感，但要注意摻量不要太高，否則就會對強度影響太大。

　　Thirdly, high bulk density. Some people believe that air entraining agents are harmful but not beneficial, so they strongly reject them. If air entraining agents are not added, it will result in high bulk density, heavy hand feel, and difficulty in scraping the plaster mortar. In fact, the air entraining agent is a panacea, and a very low dosage can effectively change the construction feel. However, it is important to note that the dosage should not be too high, otherwise it will have a significant impact on the strength.

　　第四，纖維素醚添加量。現在是冬季，冬季施工呢，纖維素醚添加量可以適當降低，如果還按照夏季時的添加量的話，就會導致砂漿稠，粘刀，不好批刮。

　　Fourth, the amount of cellulose ether added. It's winter now, and for winter construction, the amount of cellulose ether added can be appropriately reduced. If the addition amount is still the same as in summer, it will cause the mortar to become thick, stick to the knife, and difficult to scrape.

　　以上呢就是導致抹面砂漿粘刀的主要原因，如果您也出現了相同的問題，您可以自己對照排查一下，如果還有其他問題可以隨時聯系我們，我們可以幫您調整。

　　The above are the main reasons for the sticking of the plastering mortar knife. If you also encounter the same problem, you can compare and check it yourself. If there are other problems, please feel free to contact us and we can help you adjust them.
