After decoration, the house always has a pungent smell.
Even with various methods of removing formaldehyde, we still feel uncomfortable.
How to detect indoor formaldehyde, formaldehyde mainly comes from the fibers, coatings, synthetic wood, furniture used in indoor decoration.
Now the decoration is mainly outsourced to the decoration company. The era of the former self-selected decoration materials and self-selected decoration workers has passed.
We don't know about the decoration materials used by the decoration company, so when we live in a new house, we'd better test the formaldehyde in the new house.
Here are some specific methods of indoor pollution detection and prevention.
拆修后,房子老是有一股刺鼻的气息。
即便有各类往除甲醛的办法,我们仍然感应不温馨。
若何检测室内甲醛,甲醛次要来源于纤维、涂料、合成木、家具等用于室内粉饰。
目前拆修次要外包给拆修公司。
以前自选粉饰素材和自选粉饰工人的时代已颠末往。
我们不晓得拆修公司利用的拆修素材,所以当我们住在新房子里的时候,我们更好测试一下新房子里的甲醛含量。
那里有一些室内污染检测和预防的详细办法。

甲醛自测盒
Formaldehyde self-test box
Formaldehyde self-test box is the lowest cost and most family-oriented method for formaldehyde detection, but the numerical deviation is large.
Usually in the home supermarket, or online can buy formaldehyde self-test box, the price varies from more than a dozen to dozens of pieces.
甲醛自测试盒是目前国表里甲醛检测成本更低、面向家庭的办法,但数值误差较大。
凡是在家庭式超市或网上能够买到甲醛自测盒,价格从十几件到几十件不等。
Formaldehyde self-test box is generally composed of brown bottle diluent, transparent bottle color developer and a reaction box containing powder.
Before testing, the door and window of the room to be tested should be closed for one hour.
The diluent should be poured into the reaction box to dissolve the reactant fully.
The reaction box should be placed at 80 to 150 centimeters above the ground.
After 30 minutes exposure, the developer should be poured in.
The cap of the bottle should be tightened and shaken evenly.
After 10 minutes, the color scale card of the self-test box should be opened.
Yellow basically does not contain formaldehyde; yellow-green is not exceeded; yellow-green is not serious; green is a little more than the standard, blue is exceeded.
甲醛自测盒一般由棕色瓶稀释剂、通明瓶显色剂和含粉末的反响盒构成。
试验前,应封闭待测房间的门窗一小时。稀释剂应倒进反响箱中,使反响物完全化解。
反响箱应置于空中以上80至150厘米处。表露30分钟后,应倒进显影剂。
瓶盖要拧紧,摇匀。
10分钟后,翻开自测盒色标卡。
黄色根本不含甲醛;黄绿色不超标;黄绿色不严峻;绿色略高于原则,蓝色超标。
This method is simple, but the accuracy can not be guaranteed.
It can only do a general test. Industry insiders said that the formaldehyde self-test kit is not within the national indoor air testing standards, but a transitional means.
The longer the self-test kit is placed, the deeper the color of the detection reagent will be.
Therefore, the results of the formaldehyde self-test kit are not 100% accurate.
该办法简单,但不克不及包管精度。
它只能做一般的测试。业内人士表达,甲醛自检测试剂盒不契合国度室内空气检测原则,而是一种过渡性手段。
自检测试剂盒放置的时间越长,检测试剂的颜色就越深。
因而,甲醛自检测试剂盒的检测成果不完全准确。
家用甲醛检测仪
Household formaldehyde detector
JC-7 is a brand-new indoor formaldehyde concentration detection instrument. Its volume is generally the size of insulating water cup. Its front side is the display screen, its back side is the air intake hole and battery tank, and its top is the formaldehyde meter switch. It can start up after three seconds. Its side is the temperature unit button and alarm switch, which can change the temperature unit.
JC-7是一种全新的室内甲醛浓度检测仪。其体积一般为保温水杯大小。它的正面是展现屏,后背是进气孔和蓄电池箱,顶部是甲醛表开关。三秒钟后能够启动。它的侧面是温度单位按钮和报警开关,能够改动温度单位。
Household formaldehyde detector uses the latest imported electrochemical sensor and high-precision operational amplifier chip, which directly converts the formaldehyde concentration signal into electrical signal in real time and continuously. After data processing by microcomputer, the measured results are displayed by LCD digital mode. When the formaldehyde meter is placed in the detection environment or in the same closed space as the paint and other detectives, waiting for 5 to 10 minutes, the real-time formaldehyde concentration will be displayed on the display screen of the formaldehyde meter, and it will change constantly.
家用甲醛检测仪摘用最新进口的电化学传感器和高精度运算放大器芯片,将甲醛浓度信号实时持续地转换成电信号。经微机数据处置后,摘用LCD数字形式展现丈量成果。甲醛仪放置在检测情况中或与油漆及其他检测人员统一封锁空间内,期待5~10分钟,甲醛仪展现屏上会展现实时甲醛浓度,其实不断改变。
When the value on the formaldehyde meter is less than 0.10mg/m3, there will be a smiling face above the display screen number; when it is more than 0.10mg/m3, the smiling face will become a crying face, and there will be alarm sound and red light flashing; when the formaldehyde meter exceeds the standard seriously, the crying face will become a skeleton sign, and we can see the indoor formaldehyde pollution level intuitively.
甲醛表上的数值小于0.10毫克/立方米时,展现屏上会有一个笑脸;大于0.10毫克/立方米时,笑脸会酿成哭脸,会有报警声和红灯闪烁;甲醛表严峻超标时,哭脸会酿成skEleton标记,我们能够曲看地看到室内甲醛污染程度。
Compared with the detection cost of thousands of yuan for formaldehyde detection institutions, hundreds of yuan of home formaldehyde meter can fully meet the needs of ordinary families, and the operation is very simple, compact size is also easy to place.
相关于甲醛检测机构数千元的检测成本,数百元的家用甲醛表完全能够称心通俗家庭的需要,并且操做十分简单,体积玲珑也很随便放置。
甲醛检测机构
Formaldehyde Testing Company
Employing formaldehyde testing institutions to do indoor environmental testing is obviously more suitable for enterprises, units and other large institutions. It is better to entrust professional institutions to do indoor environmental testing before new houses are renovated.
用甲醛检测机构停止室内情况检测,显然更合适企业、单元等大型机构。新房拆修前更好拜托专业机构停止室内情况检测。
At present, there are a large number of institutions engaged in third-party testing, and the testing qualifications, testing instruments, testing methods are different. Few owners have relevant knowledge. How can we choose a good third-party testing organization?
目前,有大量处置第三方检测的机构,检测天分、检测仪器、检测办法各不不异。很少有业主有相关常识。我们若何抉择一个好的第三方测试机构?
Testing institutions need to pass the measurement certification (CMA) of quality and technical supervision departments at or above the provincial level before they can produce legally valid reports. Before commissioning testing, they can request testing institutions to issue measurement certification (CMA) certificates and inspection capability forms.
检测机构必需经省级以上量量手艺监视部分计量认证合格,方可出具合法有效的检测陈述。在调试测试前,能够要求测试机构出具丈量认证证书和查验才能表。
The detection methods of testing institutions should conform to the national standards. The national standards GB/T 18883-2002 do not approve the detection methods of formaldehyde, benzene and TVOC with direct reading.
检测机构的检测办法应当契合国度原则。国度原则GB/T 18883-2002不批准间接读数的甲醛、苯和TVOC的检测办法。
It should also be noted that some institutions without testing qualifications will use "free testing" to lure consumers, and the data feasibility is worth speculating, while some testing institutions that do both testing and governance suggest careful selection, because the state stipulates that testing institutions should not engage in business related to the impact of testing results.
还应该指出的是,一些没有检测资格的机构会利用“免费检测”来吸引消费者,数据的可行性值得揣度,而一些同时停止检测和治理的检测机构则定见隆重抉择,因为国度规定检测机构不该处置贸易活动。与测试成果的影响有关。
防治室内污染办法
Prevention and Control of Indoor Pollution
I. Plant Elimination
一、动物裁减法
Cephalotaxus, Aloe Vera and Tiger tail orchid can absorb a large amount of indoor formaldehyde and other pollutants to eliminate and prevent indoor air pollution; fungicides secreted by flowers such as jasmine, clove, honeysuckle and morning glory can kill some bacteria in the air, inhibit the growth of tuberculosis, dysentery pathogens and typhoid bacteria, and make indoor air clean and hygienic. Jasmine, clove, honeysuckle, morning glory and other flowers can secrete bactericides.
头杉、芦荟、虎尾兰能吸收大量室内甲醛等污染物,消弭和预防室内空气污染;茉莉、丁香、金银花、牵牛花等花卉所排泄的杀菌剂能杀死空气中的某些细菌,按捺肺结核、痢疾病原体和伤冷的生长。d细菌,使室内空气干净卫生。茉莉、丁香、金银花、牵牛花等花卉都能排泄杀菌剂。
II. Bamboo Charcoal Adsorption Method
二、竹炭吸附法
Bamboo charcoal is a new type of environmental protection product, which is made of bamboo as raw material, calcined at 1000 degrees high temperature and lasting oxygen insulation. It has super adsorption capacity. It can prevent mildew, fungi, insects and ants, regulate humidity, remove odor, release negative ions, purify air, eliminate harmful gases such as formaldehyde and benzene, shield electromagnetic waves and radiation.
竹炭是以竹子为原料,经1000度高温煅烧、耐久保氧而成的新型环保产物。具有超强的吸附才能。可防霉、防霉、防虫、防蚁、调剂湿度、除臭、释放负离子、净化空气、消弭甲醛、苯等有害气体、屏障电磁波和辐射。
III. Enhancing ventilation
三、加强通风法
In spring, summer and autumn, families should leave vents or open small windows regularly; in winter, windows should be opened at least 10 minutes early, afternoon and evening. Usually, if chemical agent is used, the window should not be closed immediately, ventilation should be at least half an hour. Pay attention to the air hygiene in the kitchen. Every time cooking is finished, windows must be opened for ventilation; when frying or frying food, ventilation should be strengthened.
在春、夏、秋季节,家庭应按期分开通风孔或翻开小窗户;在冬季,窗户应至少提早10分钟、下战书和晚上翻开。凡是情状下,假设利用化学药剂,窗户不该立即封闭,通风应至少半小时。重视厨房的空气卫生。每次烹调完毕,必需翻开窗户通风;油炸或油炸食物时,应加强通风。
