The formaldehyde pollution in Henan furniture factory is seriously disturbed. Ms. Meng is an ordinary citizen of Yanshi City, Henan Province. She couldn’t think of it. A gas she never knew was “hidden†into her life.
From the initial cough to the later blood in the sputum, and later to the difficulty of breathing, syncope, Ms. Meng spent the past year in such torture. Not only that, Ms. Meng also told reporters: "This year, people living in a street also began to appear similar symptoms to her: cough, bloody, breathing difficulties."
The results of the tests performed by the doctors were: bronchitis caused by respiratory infections or mild pneumonia. Where does the source of infection come from? Ms. Meng found that every time it rains or snows, the symptoms will be alleviated, and the most serious symptom is about 5 pm. At this time, it is the furniture factory that started construction at the end of 2009. . In order to verify her suspicions, Ms. Meng specially found a friend who had worked in the furniture factory. For the first time, she knew such a term - formaldehyde.
Hunan School Forgery Certificate çž’ "Formaldehyde Hazard" Facts The Hunan University of Science and Technology's new dormitory building was just completed on September 11th. It was originally arranged for the boys in the sophomore to senior department departments, and then adjusted on September 13th, the senior grade. Students move to voluntarily choose not to move, and the new dormitory will arrange for a new student. Just a few days after I stayed, some students felt that they couldn't stand the strong taste. They began to worry about the air quality of the dormitory. For this reason, the school also responded. The school expressed its willingness to issue an air quality test report.
On September 13, the reporter interviewed Deng Nan, the president of Hunan Science and Technology College. He stated that on the day of the 14th new arrival, the test results of formaldehyde in the indoor air of the new dormitory will be released. The reporter repeatedly asked the school about the relevant matters. Until yesterday (19th), the Minister of Propaganda of Hunan Science and Technology College made it clear that the "Civil Building Construction Indoor Air Quality Test Report" issued by two units including the Yongzhou Construction Engineering Quality Testing and Testing Center confirmed The air quality of the new dormitory is qualified.
However, this report, which was shown as qualified, has not been sent to the classmates who have been waiting for it, and the furniture quality inspection report presented by the school has appeared in a new situation. The sample name of the test report is “Blockboardâ€, and the unit under inspection is “Jiangshan Hengsheng Bamboo & Wood Products Factoryâ€. The stamped unit that passes the inspection is “Zhejiang Furniture Product Quality Inspection Centerâ€. Surprisingly, this center indicates : The test report is not for them, but forged. Although the seal is their unit, the report is also their unit, but the number and format of the report, the signature of the approver, the signature of the reviewer, and the signature of the inspector. They are not their unit.
In order to cover up the fact that furniture formaldehyde is harmful, the fake test report fools students? It is really astounding.
Shanghai IKEA responds to consumers' "formaldehyde questioning"
On the 19th, in response to the questions raised in the Morning News, Huang Yimin, Marketing Manager of IKEA Shanghai, responded: In terms of formaldehyde emission, IKEA implemented the standard of GB18584 “Restriction of Hazardous Substances in Wood Furniture for Interior Decoration Materialsâ€. This standard is a "national standard", and Mr. Wang, who had previously complained to the Morning News, said that IKEA's customer service had emphasized that IKEA was implementing "EU standards."
Huang Yimin said that in response to Mr. Wang’s complaint, IKEA will, in accordance with the provisions of the Chinese Law and the Consumer Protection Committee, promise to return Mr. Wang’s furniture for no reason at the same time with the original invoice, receipt and other documents. This incident has caused a lot of netizens to pay attention. Mr. Xie also called and said that he and Mr. Wang had similar experiences. Ikea furniture bought in 2003, still has a residual smell in the drawer. I have communicated with IKEA many times last year. I hope to send people to visit the door. Finally, I will wait for a furniture order from IKEA. Huang Yimin said that he hopes to get in touch with Mr. Xie and solve the unresolved issues of the year.
Formaldehyde has proven to be the "top killer" in the living room
Formaldehyde is recognized as a potential carcinogen in the world. It is classified as a highly toxic chemical by the state and will strongly irritate the eyes, skin, respiratory mucosa, etc., and usually cause drowsiness, weakness, chest tightness, mental paralysis and allergies. Causes abnormal immune function, liver damage and nerve central system are affected, which can lead to fetal malformation, leukemia, chronic respiratory diseases, female menstrual disorders, acute depression, nasopharyngeal cancer and other diseases, furniture caused by formaldehyde pollution, is home improvement A problem that is difficult to avoid in the process has always been the focus of attention in home consumption.
It is understood that formaldehyde has become the number one killer in the living room, especially for newborns and adolescents, formaldehyde is more harmful, seriously affecting their healthy growth. In recent years, there have been many cases in China that have caused death and carcinogenesis due to excessive formaldehyde in the decoration and newly purchased furniture. For consumers who purchase furniture, it is imperative to improve their sense of safe consumption and use furniture made of healthy plates (such as E0 grade plates).

1. floor grouting:
The flow distance should be determined based on the slit width and the liquid flow indenter to ensure that the grout flows from the gap to the front exit and the gap must not exceed 200 mm. If you guarantee a pressure head of 250mm, the maximum flow distance of up to 3 meters.
Note: The base surface must be constructed with oil-free and non-adherent loose material. If the surface of the concrete defects or slurry is cut intact before construction, the screw holes or solidified hole dust or sand blown net.
2. Floor:
Clean, no oil and other impurities must be removed to provide relief holes to ensure that all isolated areas are ventilated.
Pre-soaked: A few hours before grouting, the cleaned foundation must be submerged in water. Remove water from the free water and the hole just before pouring.
3. Stir:
To achieve the desired consistency, the amount of water must be accurate, the selected amount of water after slowly pouring it into the mixing vessel, while stirring feed, add complete package and continue stirring for 3-4 minutes until evenly dispersed, no knot Block phenomenon so far.
4. Grout:
The well-mixed material is poured over a period of 10 minutes to fully benefit from the expansion process. Each single perfusion thickness up to 200mm, the minimum width of the seam is 10mm.
5. Specific construction of large volume grouting:
Such as the thickness of more than 200mm. Aggregate grading (stones up to 10 mm in diameter) shall be added to the slurry to reduce the heat of hydration. The amount of aggregate used shall not exceed 1 part by weight of 1 part of KS series grout.
6.Low temperature construction:
When the temperature drops below 2 ° C, warm water (30-40 ° C) may be
used to accelerate the strength increase and the cementitious material
should be handled in winter.
High-temperature construction:
When the temperature exceeds 35 ℃, grouting material should be stored in a cool place, and cold water mixing.
Conservation:After grouting is complete, all exposed parts should be cured with Cask Cares or wet sacks.
Countermeasure :
KS series grout contains cement powder, which when mixed with gypsum or
when wet, releases alkali that is harmful to the skin. Avoid inhaling
dust and avoid touching the skin or eyes.
