Everyone is in the purchase of wood flooring, can choose high-quality products formaldehyde emissions, can avoid formaldehyde damage, really? The higher the temperature, the faster the formaldehyde release, use floor heating of the family, please pay attention!

，我们知道地板中的甲醛大部分来自于地板胶中的脲醛树脂。脲醛树脂是甲醛与尿素在95℃碱性条件下缩聚得到的一种聚合物，其摩尔比为(1.5 ~ 2.0)。固化后，微观结构上的不稳定基团，如游离羟基甲基、半缩醛羟基甲基、亚甲基醚键等，在压力环境条件下容易释放出结合的甲醛。另一方面，亚甲基键在酸性条件下的降解也会释放甲醛。

First of all, we know that most of the formaldehyde in the floor comes from the urea formaldehyde resin in the floor glue. Urea formaldehyde resin is a kind of polymer obtained by polycondensation of formaldehyde and urea under alkaline conditions at 95 ℃, and its molar ratio is (1.5 ~ 2.0). After curing, unstable groups in microstructure, such as free hydroxymethyl, hemiacetal hydroxymethyl, methylene ether bond, etc., are easy to release bound formaldehyde under pressure environment. On the other hand, the degradation of methylene bond under acidic conditions will also release formaldehyde.

由于释放甲醛的反应是熵增吸热反应，平衡随着温度的升高而向前移动，甲醛浓度增加，表现为室内甲醛浓度的增加。另一方面，温度的升高会加快反应速度，表现为地板甲醛释放率的升高。此外,相对湿度的增加使环境空气中的弱酸性水汽(尤其是在大城市和污染严重地区)与自由二甲基酒精反应低聚物在脲醛树脂形成甲醛,同时能促进甲醛脲醛树脂胶来解释。

Because the reaction of releasing formaldehyde is an endothermic reaction of entropy increase, the equilibrium moves forward with the increase of temperature, and the formaldehyde concentration increases, which is manifested as the increase of indoor formaldehyde concentration. On the other hand, the increase of temperature will accelerate the reaction rate, which is the increase of floor formaldehyde emission rate. In addition, with the increase of relative humidity, the weak acid water vapor in the ambient air (especially in large cities and heavily polluted areas) reacts with free dimethylalcohol to form formaldehyde in urea formaldehyde resin, and can promote formaldehyde urea formaldehyde resin adhesive to explain.

总之,每个人都在装修时,更好选择在春冬季节,装修到仲夏只是完成后,打开窗户通风,让甲醛散发尽可能住在之后,遇到天气湿度和冬季地板采暖时还需要更多的通风空气变化。

In short, everyone is in the decoration, better choice in the spring and winter season, decoration to midsummer is just finished, open the window ventilation, let formaldehyde emission as far as possible after living, encounter the weather humidity and winter floor heating, also need more ventilation air change.

家里有地暖怎么选择地面材料

How to choose floor materials when there is floor heating at home

在有地暖的家庭装修中，地面铺设材料的选择对地暖采暖有很重要的影响。高导热系数的材料是有利的热辐射,在当前常见的地面铺设材料导热系数从大到小分别是:天然石材瓷砖> >实木复合地板强化木地板> >实木地板。同时要取得采暖效果，导热系数越大的成本越小，可见木地板的地暖采暖没有经济性，再加上木地板还有遇热甲醛释放加快的缺点。但天然石材和瓷砖铺设的地面没有木地板的自然舒适，脚感冰冷。

In the home decoration with floor heating, the choice of floor laying materials has a very important impact on floor heating. The materials with high thermal conductivity are favorable for thermal radiation. The thermal conductivity of common ground laying materials from large to small are: natural stone tile > solid wood composite floor > laminate wood floor > solid wood floor. At the same time, to achieve heating effect, the greater the thermal conductivity, the smaller the cost, visible wood floor heating has no economy, coupled with wood floor has the disadvantage of accelerating formaldehyde release in case of heat. However, the natural stone and tile floor is not as comfortable as the wood floor, and the feet feel cold.

目前,更好的地板采暖地面铺设瓷砖,特别是近年来比较火的木纹砖,仿古砖等,考虑了两个已经瓷砖的导热性好,模式聚集自然又美丽的木地板等特点。和用户希望有木地板地面,更好选用实木复合地板,纯实木不适合地板采暖的地面(容易开裂变形),实木复合地板现在有专门用于地板采暖是特殊产品,铺贴时要注意完全干燥之前填充层铺设,以免使原本干燥的木地板含水率增加容易开裂变形。

At present, the better floor heating, laying ceramic tiles on the ground, especially the wood grain brick and antique brick, which are more popular in recent years, have taken into account the good thermal conductivity of the two tiles, and the environmental protection mode gathers the natural and beautiful wood floor. And users hope to have wood floor, better choose solid wood composite floor, pure solid wood is not suitable for floor heating (easy to crack and deform), solid wood composite floor now has a special product for floor heating, pay attention to the filling layer laying before complete drying when paving, so as to avoid increasing moisture content of the original dry wood floor and easy to crack and deform.
