  • 甲醛是有多可怕?

甲醛在室内达到一定浓度时,人就有不适感。大于0.08m3的甲醛浓度可引起眼红、眼痒、咽喉不适或疼痛、声音嘶哑、喷嚏、胸闷、气喘、皮炎等。

When formaldehyde reaches a certain concentration in the room, people feel discomfort. The formaldehyde concentration is greater than 0.08m3 can cause redness, itching, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis.

长期、低浓度接触甲醛会引起头痛、头晕、乏力、感觉障碍、免疫力降低,并可出现瞌睡、记忆力减退或神经衰弱、精神抑郁;慢性中毒对呼吸系统的危害也是巨大的,长期接触甲醛可引发呼吸功能障碍和肝中毒性病变,表现为肝细胞损伤、肝辐射能异常等。

Long term exposure to low concentration of formaldehyde, can cause headaches, dizziness, weakness, sensory disturbance, reduced immunity, and can appear sleepiness, memory loss or neurasthenia, depression; harm to the respiratory system of chronic poisoning is huge, long-term exposure to formaldehyde can cause respiratory dysfunction and liver poisoning disease, manifested as injury of liver cells and liver radiation abnormity.

然而人类日常生活环境里,处处洋溢着甲醛。例如,汽车尾气会排放甲醛,大约占整个大气中甲醛比例的33%。抽烟也能释放甲醛。中国科学院广州地球化学所的唐建新博士团队,曾在高速公路旁测到的甲醛浓度,在18微克/立方,即0.018毫克/立方左右。

However, in the daily living environment of human beings, it is filled with formaldehyde. For example, automobile exhaust emissions will discharge formaldehyde, which accounts for about 33% of the amount of formaldehyde in the atmosphere.  Smoking can also release formaldehyde. The concentration of formaldehyde measured by Tang Jianxin, a doctor of Guangzhou Institute of geochemistry, Chinese Academy of Sciences, was 18 micrograms per cubic meter, or 0.018 mg / cubic meter.

家里的家具和衣服,都会有甲醛释放。家具中的纤维板,大多是使用脲醛树脂热压而成,脲醛树脂就会释放甲醛,尤其是新装修的家庭,甲醛释放可能延续一年甚至数年。实木家具中,木头在储藏时,为了防腐,可能会喷洒甲醛。

The furniture and clothes in the house will be released from formaldehyde. Most of the fiberboard in furniture is made by urea formaldehyde resin, and urea formaldehyde resin releases formaldehyde. Especially in newly decorated families, formaldehyde emission may continue for a year or even a few years. Wood furniture, wood in storage, in order to antiseptic, may spray formaldehyde.

新买的衣服和布料中也可能有甲醛,因为为了防皱和让染料更好的上色,会使用一些含甲醛的助剂,也会释放。还有,涂料墙纸中,会使用含有甲醛。

The new clothes and cloth may also have formaldehyde, because in order to prevent wrinkles and make the dye better color, the use of some formaldehyde containing additives, will also be released. Also, the paint wallpaper, will be used to contain formaldehyde.

由此可见,零甲醛环境,在生活中很难存在。而甲醛的致病风险,要看浓度和剂量。低于一定浓度,对健康的损害可以忽略不计,而高于一定浓度,则会根据个人体质、抵抗力以及不同剂量的甲醛浓度,产生不一样的健康损害。2-16021Q93058.jpg

It can be seen that the zero formaldehyde environment is difficult to exist in life. And the pathogenic risk of formaldehyde depends on the concentration and dose. Below a certain concentration, the damage to health can be ignored, but higher than a certain concentration, it will produce different health damage according to personal physique, resistance and different concentration of formaldehyde concentration.

那么到底多少的甲醛浓度,才不会危害健康呢?我国的室内空气质量标准中,对甲醛的室内安全浓度,定为不高于0.08毫克/立方。这个标准正好接近0.07毫克的呼吸道最低影响值。室内甲醛浓度只要低至国家标准的限值,就是安全的。

So how much formaldehyde concentration will not harm health? In China's indoor air quality standards, the indoor safety concentration of formaldehyde is not more than 0.08 mg / cubic. This standard is close to 0.07 milligrams of the lowest respiratory tract. Indoor formaldehyde concentration is low as long as the limit of national standard, it is safe.

如果室内甲醛超标,我们可以先保持室内空气流通,也就是俗称的“通风”!通风会把室内家居不断释放的游离甲醛带走一部分,从而减少部分室内甲醛和其他污染物的浓度,以及异味。

If indoor formaldehyde exceeds the standard, we can keep indoor air circulation first, that is, "ventilation". Ventilation will take away a part of the free formaldehyde free formaldehyde released in the house, thereby reducing the concentration of indoor formaldehyde and other pollutants, as well as the odor.

然后可以使用含有吸附分解功能的除醛产品百纳纯,百纳纯含有特研百纳土和冷触媒,可以把吸附到的甲醛分解成二氧化碳和水,因此特性使用有效期也延长至3年,不会产生二次污染和副作用,入住后也可以继续使用。

You can then use the adsorption decomposition function in addition to aldehyde containing products containing pure pure Cabernet, Cabernet teyan bynano soil and cold catalyst, can put the formaldehyde adsorption to decompose into carbon dioxide and water, so the characteristics of validity period is extended to 3 years, will not have two pollution and side effects, in also can continue to use.

两种方法同时使用,可以快速降低室内甲醛含量,有效控制甲醛含量处于达标范围之内。

The two methods are used at the same time, which can quickly reduce the content of indoor formaldehyde and effectively control the content of formaldehyde within the range of standard.

甲醛是一个逃避不了的东西,但只要通过合理有效的处理方式,把甲醛浓度维持在安全的水准,大可放心入住。不必过于忧心甲醛,有甲醛时治理即可。

Formaldehyde is an inescapable thing, but as long as through reasonable and effective treatment, the concentration of formaldehyde in a safe level, can be assured to stay at ease. Do not have to be too worried about formaldehyde, when there is formaldehyde, it can be treated.
