class="showcontent"><p><strong><span style="font-size: 17px;"> 甲醛的來源<br></span></strong> 甲醛是一種來源廣泛的空氣污染物，自然界中的甲屋是甲烷循環中的一個中間產物，背景值低,一般小于0.03mg/m,城市空氣中甲路平均濃度為0.005~0.01mg/m。甲醛因其化學反應強烈,價格低廉，在一百多年前就廣泛用于工業生產，但脲醛樹脂黏合板材發明之初并沒有得到廣泛的使用，可是由于其具有反應性能活潑、價格低廉等優良的特性,越來越引起人們的廣泛注意和大量使用。甲醛在化工工業上的用途主要是作為生產樹脂的重要原料, 例如脲醛樹脂、三聚氰胺甲醛樹脂、酚醛樹脂等，這些樹脂主要用作黏合劑和涂料中的基料，我國脲醛膠樹脂的年產量為40萬噸，約占整個人造板(膠合板、刨花板和纖維板)用膠量的80%，因此在室內裝修中大量人造板材的使用使得甲醛成為一種普遍存在的揮發性室內污染物。 <img class="fr-fin" data-fr-image-preview="false" alt="Image title" src="/uploads/allimg/191126/3a3f920c7b876e7a54c524ee143564a4.jpg" width="300"></p><p><br> 我國質量監督檢驗檢疫總局和國家標準化管理委員會于 2001年12月10日批準發布并于2002年1月1日實施的10項關于室內裝飾裝修材料有害物質限量的標準中就有8項涉及甲醛。我國的甲醛室內標準為0.08mg/m3，與其他有害物相比甲醛含量極易超標，裝修材料及家具中的膠合板、大芯板、中纖板、刨花板(碎料板)的黏合劑遇熱、潮解時甲醛就釋放出來，是室內最主要的甲醛釋放源。各種紡織品如床上用品、墻布、化纖地毯、窗簾和布藝家具等也是甲醛污染源之一。為了增強紡織品抗皺性能、防水性能、防火性能,在生產中常加人一些含有甲醛的助劑，在使用時會釋放出甲醛。室內空氣中甲醛的危害屬于第一位。而且甲醛的釋放期在3-15年之久。因此對室內居住的人的影響會很大。</p><p> 因此室內新裝修的房間，需要進行<a href="http://www.yw523.com/" rel="nofollow" target="_blank">除甲醛</a>，<a href="http://www.yw523.com/" rel="nofollow" target="_blank">北京除甲醛</a>的公司也不少，需要從從業時間，從業資質，產品安全，施工人員專業，施工案例等方面，進行綜合考察。 </p><p> <span style="background-color: #F3F3F3;"> </span><strong><span style="background-color: #F3F3F3; color: rgb(147, 147,
