1. Look: the surface of high-quality fireproof board should be smooth and smooth, without defects. From the side, see whether the thickness of the board core is uniform. Manufacturers of glass magnesium fireproof board, blockboard and multi-layer board should observe whether there is overlapping and core separation. Density board is the best base plate for fireproof board. It can keep the smoothness of fireproof board for a long time. Generally, the texture of a stack of fireproof boards is indistinguishable, most of which are artificial veneers. The dyed veneers only need to be dipped in water and rubbed gently when selecting. The faded ones are dyed. The natural veneers are beautiful and generous. The texture of each board is not the same, but they are beautiful and different.

2、摸：用手觸摸一下細(xì)木工板、集成材和多層板表面，優(yōu)良的板應(yīng)手感干燥，平整光滑，橫向觸摸無(wú)波浪形，說(shuō)明含水率低，平整度好。

2. Touch: touch the surface of joinery board, Glulam and multi-layer board by hand. Excellent board should feel dry, flat and smooth, and there is no wavy shape when touching horizontally, indicating low moisture content and good flatness.

             

3、聞：用鼻孔貼進(jìn)材聞一下，如果細(xì)木工板散發(fā)清香的氣味，說(shuō)明甲醛含量較低，如果氣味刺鼻則說(shuō)明甲醛含量較高。

3. Smell: use nostrils to stick wood to smell. If the blockboard gives off a delicate smell, it means that the formaldehyde content is low. If the smell is pungent, it means that the formaldehyde content is high.

4、查：查一下產(chǎn)品的各種標(biāo)識(shí)，如是否正規(guī)廠家生產(chǎn)的商標(biāo)、出廠合格證、生產(chǎn)地址售后服務(wù)電話、防偽標(biāo)志、環(huán)境標(biāo)志、甲醛釋放量和膠合強(qiáng)度值等。

4. Check: check all kinds of marks of the products, such as whether the trademark of the regular manufacturer, factory certificate, production address, after-sales service telephone number, anti-counterfeiting mark, environmental mark, formaldehyde emission and bonding strength value, etc.

5、價(jià)格：不要貪圖防火板價(jià)格便宜，建議選擇一些具有一定知名度及獲得我國(guó)各部門認(rèn)可的產(chǎn)品。美國(guó)的富美家可能要稍微貴一點(diǎn)，國(guó)內(nèi)的防火板價(jià)格就能低一點(diǎn)，但采用的生產(chǎn)設(shè)備和原料都是進(jìn)口的，所以質(zhì)量也是可以放心的！

5. Price: don't be greedy for the cheap price of fireproof board. It is suggested to choose some brand products with certain popularity and recognized by various authoritative departments in China. Fumika in the United States may be a little more expensive. The price of domestic fireproof board brands can be lower, but the production equipment and raw materials used are imported, so the quality can be assured!
