1. Flammability.

　　磨削有嚴格的操作規程，并使用專用磨床進行試驗。研磨試驗用砂紙為120目(no。0)，膩子試樣的重復摩擦次數為5次。終指標為“砂紙面積20% ~ 80%目測合格”。

　　There are strict operating rules for grinding, and special grinding machine is used for testing. The grinding test was carried out with 120 meshes of sandpaper (no). The repetitive friction times of putty samples are 5 times. The final index is "20% to 80% of the sand paper area is qualified by visual measurement".

　　需要強調一點,膩子打磨性測試是在批準第二天刮膩子(節約1天在標準條件下),通常來說,膩子佳光澤時間也在膩子后3天膩子墻內,希望墻面立即當大量白色光澤,膩子干后,光澤可以比較困難。

　　It should be emphasized that the test of putty grindability is to scrape putty the next day after approval (save 1 day under standard conditions). Generally speaking, the best gloss time of putty is also in putty wall three days after putty. It is hoped that the wall surface will be white and gloss will be more difficult when putty is dry.

　　2. 粘接強度。

　　2. Bond strength.

　　粘結強度分為兩種。一種是行業內的標準狀態，即干強度，另一種是行業內的濕強度。

　　There are two kinds of bond strength. One is the industry's standard state, namely, dry strength, and the other is the industry's wet strength.

　　與磨削性能測試不同，粘結強度測試時間在刮除后至少為7天(干強度維持7天，濕強度在干強度的基礎上維持7天，加4天共11天)。

　　Unlike grinding performance test, bond strength test time is at least 7 days after scraping (dry strength is maintained for 7 days, wet strength is maintained for 7 days on the basis of dry strength, plus 4 days for 11 days).

　　在粘結強度方面，浸漬后的狀態符合N型標準(且防水膩子)只需進行測量，所謂浸漬，就是完全浸沒在水中48小時，不耐水的膩子無法測量，浸漬后直接起泡、脫落。

　　In terms of bond strength, the state after impregnation conforms to the N-type standard (and waterproof putty) only needs to be measured. The so-called impregnation means that the putty is completely immersed in water for 48 hours, and the water-resistant putty can not be measured. After impregnation, the putty foams and falls off directly.

　　防水膩子完全干燥后，粘結強度更高，表面結構更牢固，磨削難度更大。膩子粘接強度越高，粘接強度越大。

　　After the waterproof putty is completely dried, the bonding strength is higher, the surface structure is stronger, and grinding is more difficult. The higher the bonding strength of putty, the greater the bonding strength.

　　結論:1、墻面拋光是墻面裝飾中非常重要的一個環節，是提高墻面光潔度、細致度和終效果的重要手段。

　　Conclusion: 1. Wall polishing is a very important link in wall decoration. It is an important means to improve the wall finish, meticulousness and final effect.

　　2. 為了在墻面拋光過程中隨時觀察墻面的平整度，白天或晚上都要手持至少200瓦的燈泡。

　　2. In order to observe the smoothness of the wall at any time during the polishing process, at least 200-watt light bulbs should be held in hand during the day or at night.

　　3墻砂紙的選擇不是越厚越好,并不是越細越好,一般先從細砂紙開始玩,不能移動改變粗砂紙,但終用細砂紙再次re-polish,為了確保墻細致,沒有劃痕。

　　3 The choice of wall sandpaper is not the thicker the better, not the finer the better. Generally, we start with fine sandpaper and can't move and change coarse sandpaper, but finally use fine sandpaper to re-polish again. In order to ensure the meticulous wall, there are no scratches.

　　4、良好的團隊改善主人家里墻面的使用壽命,建議使用可以耐水膩子,即使光澤有點難度,和黑心病的團隊可以拒絕使用耐水膩子用各種各樣的借口,一切從自己省力,不考慮所有者。

　　4. A good team can improve the service life of the wall in the owner's house. It is suggested to use water-resistant putty, even if the gloss is a little difficult, and the team with black heart disease can refuse to use water-resistant putty under various excuses, all from their own efforts, regardless of the owner.

　　5、膩子打磨性,它在膩子批準打擊后1天的測試,通常來說,膩子的能夠有更好的耐水膩子墻面泛白,沒有完全干燥之前徹底進行打磨,此刻強度較低,表面結構還不是公司,增加光澤更節省精力。膩子完全干燥后，粘結強度高，表面結構牢固，磨削困難。

　　5. Putty abrasiveness. It is tested one day after putty approval. Generally speaking, putty can have better water-resistant putty wall whitening. It is thoroughly polished before it is completely dry. At the moment, the strength is low, the surface structure is not a company, and increasing luster saves more energy. After the putty is completely dried, the bonding strength is high, the surface structure is firm, and grinding is difficult.

　　6. 膩子的粘結強度直接決定了膩子今后的使用壽命和耐水性。在條件允許的情況下，粘結強度較高的貴州膩子粉具有較好的長期性價比。

　　6. The bonding strength of putty directly determines the future service life and water resistance of putty. Guizhou putty powder with higher bonding strength has better long-term performance-price ratio when conditions permit.
