Imitate the porcelain tableware and release formaldehyde after poaching The density is equivalent to the new house of 30 tie
The laboratory technician adopts the air quality tester, measure test tube and air pump through the vacuum, utilize phenol reagent spectrophotometer method, read the number value on the test tube after the responses of about 30 minutes, reveal the consulting value of formaldehyde content is 0.22mg/m3. Reporter in happy to purchase the intersection of supermarket and muddy south shop, buy two imitative porcelain plates go on the experiment. Reporter Li Ying takes the photograph Imitate the porcelain tableware, also called the dense amine tableware, it is one kind that gather the amine formaldehyde resin substrate of cyanogen, is based on a cellulose the appearance that is made of material and similar to the tableware of the porcelain by three, more solid, non- more fragile than the porcelain, and bright in colour, smooth finish is strong, are liked by woman's children very much. But the related departments find in checking, are imitating the production ink of the porcelain tableware, existing substitutes with urea aldehyde resin and gathers the situation made the imitative porcelain tableware for the substrate of cyanogen amine formaldehyde resin three times. The intersection of urea and the intersection of aldehyde and resin urea and the intersection of formaldehyde and income go on, react, at certain temperature, the urea will be separated with formaldehyde, release formaldehyde, cause danger to the health. A few days ago, reporters visited many supermarkets, market of Shenyang, carried on the investigation in imitating porcelain tableware security. Why does our imitative porcelain tableware chock the nose? ! Yesterday, this newspaper " the curiosity was tested " The postbox receives a letter of Shenyang citizen Mr. Wang. I in happy to purchase the intersection of supermarket and muddy south shop, choose, imitate the intersection of porcelain and tableware by two. Not only the pattern is interesting, but also convenient to use, child likes the style very much. I take the plate and go home, plan to disappear and sterilize first with the boiled water, the plate is cooked soon, smell a whiff of pungent taste, that taste can not be spoken well, as if just fitted up that stream of flavor in the house. I surf the Net to inquire immediately, CCTV reports, say the qualification rate of imitating the porcelain tableware on the market is fewer than 20%, is our imitative porcelain tableware qualified? Hope you help me to measure. Host: The 34th experiment project of Zhang Lei is often used for containing the imitative porcelain tableware of the high-temperature food, safe? Test time for November 8, November 15 The experiment apparatus LB-3J divides all luminosity to unify the indoor air quality detector six times. This is that the domestic and foreign and only one can measure indoor formaldehyde live at the same time at present, a kind of effective and simple tester of harmful gas such as ammonia, benzene, toluene, Xylene, TVOC. Suitable for house, office, hospital, kindergarten, hotel,etc., print the examining report which customize the form in on-the-spot temperature sensing of 30 minutes. The experiment principle measures test tube and air pump through the vacuum, collect it the air in examining the environment, after reacting, read the number value on the test tube, to confirm the content of formaldehyde in the air. Clean clean Environmental Technology Co., Ltd. of Shenyang of technical support, established in 2004, it was a Hi-Tech environmental protection service enterprise at city level under a department of chemistry of chemical engineering institute of Shenyang, absorbed in the basic research of the indoor little climate field, initiate " indoor ecosphere in environment protecting mode " The scientific research field, become the key laboratory of Liaoning Province, it is one of the domestic most professional indoor environmental protection enterprises. Sample of this experiment is selected at random, influence going on under the condition in considering atmospheric pressure, temperature etc., only to being examined sample. Experiment quantitative to find for half, the resulting data, for the consulting value. The experiment is poached the formaldehyde density of the imitative porcelain tableware quite equals the new clothes house for 30 times Reporter in large the intersection of western food and competent, the intersection of groceries and shop near the the intersection of Shenyang and the intersection of cooking utensil and city, the intersection of Shenyang and the intersection of city and large mega-stores, have seen the imitative porcelain tableware sold. Even the street peddler setting up a stall by the street, there is imitative porcelain tableware of sale. The porcelain dinner-ware sold more compared with the large supermarket, the price of these tablewares is much lower, so has attracted a lot of citizens to buy. Compared with imitative porcelain tableware that the supermarket sells, the tableware price of imitative porcelain that the street peddler sold is a little cheaper slightly by the street, but can not part on quality. According to sample that Mr. Wang offer, reporter in happy to purchase the intersection of supermarket and muddy south shop, buy two the same imitative porcelain plates go on the test. On the trade mark under the plate, mark out " nonpoisonous, tasteless, shock-resistant, is able to bear 120 �� warmly ", and forbid putting the microwave oven to heat " . The reporter puts two plates into pans on the electromagnetism stove, energize, heat water in the pan to and boil. As steam is full of whole pan, giving out a stream of pungent smell in air vent hole on the pot cover, smell that very similar plastics of this kind of smell produce after burning. Heat the longer time, the denser the smell is. Heat at the same time, utilize the air quality tester, measure test tube and air pump through the vacuum, collecting the steam in the pan constantly. About 30 minutes later, it is long while reaching the collection stipulating, will collect the already liquefied vapor in the tube, quench into the test tube equipped with acetyl propanone, after acetyl propanone is totally dissolved and reacted, the result shows heating in the pan which imitates the porcelain tableware, the consulting value of content of formaldehyde is 0.22mg/m3. Originally transparent test tube, has become ink of pen -like and violet-blue. According to the requirement in " indoor air quality criteria ", the formaldehyde content standard is 0.08-0.12mg/m3. The number value that the experiment revealed is fully more than 2 times of standard number value more than! The persons who operate the detection of the experiment Mr. Yin introduces, in his daily indoor air that measures, rooms about 30 square meters usually just fitted up with the better-than-average renovation material, the intersection of formaldehyde and density and imitate the intersection of porcelain and tableware, it releases formaldehyde that comes out to be about equal in density. Originally transparent test tube, has become ink of pen -like and violet-blue. As to the formaldehyde content in the imitative porcelain tableware that the experiment uses, it is " not up to standard " to print one and is shown in experiment . Formaldehyde density is unexpectedly higher than imitative porcelain tableware by a lot of families and like spreading the crystal board on the dining table after crystal board heats the experiment two, not merely it is convenient to clear up, can prevent the high-temperature tableware from contacting the dining table directly at the same time, do harm to tabletop. Perhaps you did not think, the crystal board likewise related to resin material, also release formaldehyde " The killer " . After the crystal board has been just put into the electromagnetism stove after heating, give out the pungent smell immediately, soften deformation at the same time. After collecting the inner air of the pan for 30 minutes, it is 0.24mg/m3 to measure formaldehyde density, are slightly higher than the imitative porcelain tableware. You are while choosing the tableware that curious general knowledge tries hard to select light to imitate the porcelain tableware, go to regular store and supermarket to buy, will try hard to choose the imitative porcelain tableware with qualified quality; See it is out of shape whether the tableware has; Children mustn't use the imitative porcelain tableware with bright color, especially the inboard printed stamp, should try hard to select the imitative porcelain tableware of the light color. Qualified imitative the intersection of porcelain and tableware can put into refrigerator, can also the boiling water is cooked, security is relatively high. While using the imitative porcelain tableware, try not to hold the acid, oily, alkaline food for a long time; Don't especially imitate the porcelain tableware to heat with microwave oven, will prevent releasing the noxious substance. Just bought Imitative for porcelain for tableware,it is last more than two minute not to should add by vinegar to boiling water, or soak on the two hour vinegar at room temperature, let the harmful substance of the tableware top layer of imitative porcelain be released out, boil? It knocks to be the intersection of �� and bits and the intersection of �� and the intersection of ditch and Qu, G of bamboo mat, beat hillfoot stop the intersection of way and the intersection of purine and the intersection of coin and �� sprout where does it rise abruptly vastly on the way ��� Pai whiz skin of mark Does �� Shan Zhang thread and knock into the fine grain �� to murder �� Li's looks gray �ѡ� of Zhyuan chaste tree of Gui ����'s money stilbene of rice huller on the way disrespectfully?
