Decorative fire-proof board is a board, and face sticking is well known. In the ordinary use process, we usually use white latex or general adhesive, but in the use of glue bar, many friends find that this article is a good use of fire-proof board will expand over time, so it is difficult to adjust, if you can only replace the whole protruding place a lot;

　　那么出現(xiàn)這種防火板使用膠粘貼后鼓包的情況怎么辦?下面跟隨富美家小編一起來看!

　　So what happens when the fire-proof board is pasted with all-purpose adhesive and the drum bag is pasted? Let's take a look at it together with the small weasel of fumeijia!

　　防火板什么時(shí)候用膠貼，容易膨脹?

　　When is the fireproof board pasted with all-purpose adhesive and easy to expand?

　　原因分析:

　　Cause analysis:

　　1、板材上的漆膜施工不干燥，對(duì)底板進(jìn)行粘接，導(dǎo)致多粘接劑膜粘接低，中間的溶劑不能揮發(fā)導(dǎo)致板材起泡;

　　1. The construction of paint film on the plate is not dry, and the base plate is bonded, resulting in low adhesion of multi adhesive film, and the solvent in the middle can not volatilize, resulting in foaming of the plate;

　　2、在粘貼過程中，板材之間的空氣沒有消除;

　　2. During the pasting process, the air between the plates is not eliminated;

　　3、涂膠時(shí)厚度不均勻或缺膠，導(dǎo)致膠面無膠或少膠，影響粘接強(qiáng)度。但在揮發(fā)過程中，少量非揮發(fā)性溶劑被濃縮，導(dǎo)致局部張力大于粘附;溶劑揮發(fā)速率與小行程不一致，導(dǎo)致溶劑揮發(fā)不完全;

　　3. Uneven thickness or lack of glue during gluing, resulting in no or less glue on the glue surface, affecting the bonding strength. However, in the process of volatilization, a small amount of non-volatile solvent is concentrated, resulting in local tension greater than adhesion; the rate of solvent volatilization is not consistent with the small path, resulting in incomplete solvent volatilization;

　　4、潮濕天氣施工膠水干燥時(shí)間不夠也容易出現(xiàn)起泡現(xiàn)象。

　　4. The drying time of construction glue in wet weather is not enough, and it is easy to blister.

　　富美家小編為您介紹防火，解決方案:

　　We will introduce you fire prevention solutions:

　　1、延長(zhǎng)干燥時(shí)間，使溶劑在薄膜中完全揮發(fā);

　　1. The drying time was prolonged to make the solvent volatilize completely in the film;

　　2、盡量往側(cè)面粘貼或從中間向四周滾出空氣;

　　2. Stick it to the side or roll out air from the middle to the surrounding as far as possible;

　　3、刮膠時(shí)盡量使膠水厚度均勻，不要出現(xiàn)缺膠現(xiàn)象;

　　3. When scraping, try to make the glue thickness uniform, and do not lack glue;

　　4、可在底板上鉆孔若干個(gè)空氣孔，增加透氣性;

　　4. Several air holes can be drilled on the bottom plate to increase the air permeability;

　　5、加熱薄膜，提高活化溫度。

　　5. Heating the film to raise the activation temperature.

　　6、發(fā)泡現(xiàn)象出現(xiàn)后，可用電熨斗加熱，用濕毛巾(溫度:50-60℃)熨燙即可解決。

　　6. After foaming, it can be heated with an electric iron and ironed with a wet towel (temperature: 50-60 ℃).
