  • 无纺布墙纸真的环保吗?
  • 本站编辑:湖州耀锦无纺科技有限公司发布日期:2020-02-29 19:00 浏览次数:
平时大家关心的墙纸是否环保的问题,确切地说,应该是:是否含有甲醛或者排放甲醛的问题。不过,墙纸中哪怕是使用了溶剂型油墨,也不要怕,它挥发掉了也就不会再对人体有伤害了。尤其是PVC材料的,挥发快。可能会一下子来了很强的刺激性气味,不过,很容易过几天就没有大碍了。
 
墙纸是否环保主要依据VOC排放衡量
 
目前,很多人对环保概念比较模糊,不过,这个事情却是十分有必要搞清楚的,因为只有清楚了以后,关于这个事情的一切才更好办。
建筑装饰材料的环保分三个方面来讲:,材料本身,是否使用了过多的自然资源;其次,材料废弃之后,是否能够自然解降(俗称:烂掉);再次,材料在使用过程中,是否过多地并且持续地排放VOC,解降过程中是否有排放有毒物质。
为了增强针对性,靠前条,在此就不做解释了,因为事实上大家也都没有那么关心这个事情。现在,需要重点说一下的是第二条。比较一下无纺和PVC。PVC是化工产品,合成树脂,是高分子聚合物,是石油化工的衍生产品。PVC的可塑性强,应用广泛,大家穿的衣服,家里微波炉的专用碗筷等都是或者至少含有PVC材料。这种材料很难在自然界中解降,甚至要用几百上千年才能够使高分子链断裂,完成解降过程。所以不是环保材料。
 
无纺纸(俗称:无纺布),是没有方向性的一种织造,也就是非经纬织造,结构相对松散,能够比较容易地在自然界中解降,所以相对于PVC而言,是比较环保的材料。
 
这两种材料环保性的比较依据是它们被废弃之后对环境的污染程度或者解降这些材料所使用的能源(或者叫自然资源)的多少。
 
另外,如果要讲材料本身的纯净度,PVC,属于高分子聚合物,比较单纯;反而无纺布的材料比较乱,无纺是一种织造方法,不是材料本身。可以是杂七杂八的材料无纺。
 
第三条,便是关于VOC排放。VOC=volatile organic compounds=易挥发的有机化合物=甲醛,乙醚,乙醇等,鉴于我们比较关心的是甲醛,那就简称之为甲醛排放。
At ordinary times, people are concerned about whether wallpaper is environmentally friendly. Specifically, it should be: whether it contains formaldehyde or emissions formaldehyde. However, even if you use solvent based inks in wallpaper, don't be afraid that it will no longer be harmful to human body if it evaporates. Especially PVC material, volatile fast. There may be a strong irritant smell all of a sudden, but it's easy to get out of the way in a few days.
 
 
 
The environmental protection of wallpaper is mainly based on VOC emission measurement
 
 
 
At present, many people are vague about the concept of environmental protection, but it is necessary to make it clear, because only when it is clear can everything about this matter be better done.
 
The environmental protection of building decoration materials can be divided into three aspects: first, whether the materials themselves use too much natural resources; second, whether the materials can be naturally degraded after being abandoned (commonly known as rotten); third, whether the materials discharge VOC too much and continuously in the use process, and whether toxic substances are discharged in the degradation process.
 
 
 
In order to enhance the pertinence, the first article is not explained here, because in fact, everyone is not so concerned about this matter. Now, we need to focus on the second one. Compare non-woven with PVC. PVC is a chemical product, synthetic resin, high polymer and derivative product of petrochemical industry. PVC has strong plasticity and is widely used. The clothes we wear and the special dishes and chopsticks in the microwave oven at home are or at least contain PVC materials. This kind of material is very difficult to be degraded in nature, and it will take hundreds of thousands of years to break the polymer chain and complete the degradation process. So it's not environmentally friendly.
 
 
 
Nonwoven paper (commonly known as non-woven fabric) is a kind of weaving without direction, that is, non warp and weft weaving. Its structure is relatively loose and it can be easily disintegrated in nature. Therefore, compared with PVC, it is a more environmentally friendly material.
 
 
 
The comparison of environmental protection between the two materials is based on the degree of environmental pollution or the amount of energy (or natural resources) used to reduce these materials after they are discarded.
 
 
 
In addition, if we want to talk about the purity of the material itself, PVC belongs to high polymer, which is relatively simple; on the contrary, the material of non-woven fabric is relatively disordered, and non-woven is a weaving method, not the material itself. It can be nonwoven.
 
 
 
The third is about VOC emissions. VOC = volatile organic compounds = volatile organic compounds = formaldehyde, ether, ethanol, etc. since we are most concerned about formaldehyde, it is called formaldehyde emission for short.
