1. Flammability.

　　磨削有嚴(yán)格的操作規(guī)程，并使用專用磨床進(jìn)行試驗(yàn)。研磨試驗(yàn)用砂紙為120目(no。0)，膩?zhàn)釉嚇拥闹貜?fù)摩擦次數(shù)為5次。終指標(biāo)為“砂紙面積20% ~ 80%目測(cè)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(qiáng)調(diào)一點(diǎn),膩?zhàn)哟蚰バ詼y(cè)試是在批準(zhǔn)第二天刮膩?zhàn)?節(jié)約1天在標(biāo)準(zhǔn)條件下),通常來(lái)說(shuō),膩?zhàn)蛹压鉂蓵r(shí)間也在膩?zhàn)雍?天膩?zhàn)訅?nèi),希望墻面立即當(dāng)大量白色光澤,膩?zhàn)痈珊?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(qiáng)度。

　　2. Bond strength.

　　粘結(jié)強(qiáng)度分為兩種。一種是行業(yè)內(nèi)的標(biāo)準(zhǔn)狀態(tài)，即干強(qiáng)度，另一種是行業(yè)內(nèi)的濕強(qiáng)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(cè)試不同，粘結(jié)強(qiáng)度測(cè)試時(shí)間在刮除后至少為7天(干強(qiáng)度維持7天，濕強(qiáng)度在干強(qiáng)度的基礎(chǔ)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(jié)強(qiáng)度方面，浸漬后的狀態(tài)符合N型標(biāo)準(zhǔn)(且防水膩?zhàn)?只需進(jìn)行測(cè)量，所謂浸漬，就是完全浸沒(méi)在水中48小時(shí)，不耐水的膩?zhàn)訜o(wú)法測(cè)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?zhàn)油耆稍锖螅辰Y(jié)強(qiáng)度更高，表面結(jié)構(gòu)更牢固，磨削難度更大。膩?zhàn)诱辰訌?qiáng)度越高，粘接強(qiáng)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(jié)論:1、墻面拋光是墻面裝飾中非常重要的一個(gè)環(huán)節(jié)，是提高墻面光潔度、細(xì)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(guò)程中隨時(shí)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(xì)越好,一般先從細(xì)砂紙開(kāi)始玩,不能移動(dòng)改變粗砂紙,但終用細(xì)砂紙?jiān)俅蝦e-polish,為了確保墻細(xì)致,沒(méi)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(tuán)隊(duì)改善主人家里墻面的使用壽命,建議使用可以耐水膩?zhàn)?即使光澤有點(diǎn)難度,和黑心病的團(tuán)隊(duì)可以拒絕使用耐水膩?zhàn)佑酶鞣N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?zhàn)哟蚰バ?它在膩?zhàn)优鷾?zhǔn)打擊后1天的測(cè)試,通常來(lái)說(shuō),膩?zhàn)拥哪軌蛴懈玫哪退佔(zhàn)訅γ娣喊?沒(méi)有完全干燥之前徹底進(jìn)行打磨,此刻強(qiáng)度較低,表面結(jié)構(gòu)還不是公司,增加光澤更節(jié)省精力。膩?zhàn)油耆稍锖螅辰Y(jié)強(qiáng)度高，表面結(jié)構(gòu)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?zhàn)拥恼辰Y(jié)強(qiáng)度直接決定了膩?zhàn)咏窈蟮氖褂脡勖湍退浴Ｔ跅l件允許的情況下，粘結(jié)強(qiáng)度較高的貴州膩?zhàn)臃劬哂休^好的長(zhǎng)期性價(jià)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.
