The quality and safety of children's furniture is worrying.
The results of the spot checks showed that 131 batches of children's furniture, including children's tables, children's chairs, children's cabinets, etc., were inspected and tested, and 46 batches were qualified, with a pass rate of only 35%. Among the unqualified batches, 64 batches of structural safety were unqualified, 23 batches of formaldehyde emission were unqualified, 5 batches of heavy metal content exceeded the standard, 1 batch of mechanical properties were unqualified, and 80 batches of children's furniture warning signs were not. qualified.
The 23 batches of children's furniture with unqualified formaldehyde emission are all plate furniture. The formaldehyde emission is mainly due to the use of adhesives in the production of MDF, particleboard, large core board and plywood used in panel children's furniture. A major cause of formaldehyde exceeding the standard.
E-commerce platform sampling pass rate is the lowest
It is understood that the Jiangsu Provincial Quality Supervision Bureau sampled 131 batches of children's furniture samples, sampling 27 batches from the production enterprises, 48 ​​batches purchased from the physical store, and 56 batches purchased from the network e-commerce platform. Among them, 75 samples from the production enterprises and physical stores were sent to the Suzhou Quality Inspection Group for testing, and 56 batches of samples purchased from the network platform were sent to the Xuzhou Quality Inspection Center for testing.
According to Wang Haoming, an engineer of the Suzhou Quality Supervision Institute, they are based on the general technical conditions of GB28007-2011 children's furniture, and the limit of harmful substances in the wooden furniture of GB18584-2001 interior decoration and decoration materials, formaldehyde, warning signs, mechanical properties in children's furniture, The five projects of heavy metal content and structural safety were supervised and spot-checked. According to the QB/T2929-2008 solvent-based ink solvent residue limit and its determination method, a risk monitoring was carried out on the solvent residue project.
According to reports, the Suzhou Quality Inspection Team and the Xuzhou Quality Inspection Center adopted the same standards and methods for simultaneous testing. The results showed that among the 27 batches sampled by the enterprise, 23 batches were qualified, and the pass rate was 85%. Among the 48 batches purchased from the physical store, 23 batches were qualified, and the pass rate was 48%. The 56 batches purchased from the platform had a pass rate of zero.
Among the 56 batches of children's furniture purchased on the e-commerce platform, more than 96% of children's furniture have structural safety problems, while more than 90% of the furniture warning signs are unqualified, and about 40% of the formaldehyde content exceeds the standard, the most serious over-standard 7 times. Furniture that is not solid wood and has no warning signs includes most quality issues.
According to the inspection personnel, the reason for the relatively low qualification rate of online shopping furniture is that the furniture manufacturers on the e-commerce platform are not good at all. Some small workshops and small enterprises blindly pursue low-cost sales and maximum profits, while the online sales platform lacks perfect supervision. Not only does the product not have a perfect brand, but there are also problems with unsafe structures and excessive levels of toxic and hazardous substances.
Structural safety half of the products failed
After testing, among the 131 batches, 64 batches were unqualified in structure safety, 23 batches of formaldehyde were unqualified, 5 batches of heavy metals exceeded the standard, 1 batch of mechanical properties were unqualified, and 80 batches of children's furniture warnings were issued. The logo is unqualified. Even though nearly half of the children's furniture structure is not safe, what kind of standards should children's furniture with structural safety be qualified?
According to Fang Zhengjie, an engineer at the Xuzhou Quality Inspection Center, children's furniture with structural safety and safety should have at least three standards: First, there should be no dangerous sharp edges and edges. All corners and edge parts should be rounded. Chamfering treatment; secondly, the clearance of the small holes or moving parts on the furniture should be less than 5 mm, or more than 12 mm, in case the children's fingers are stuck in the small holes or gaps; again, the sliding parts of the drawers of the furniture should be Install a pull-out device to prevent accidental bruising of the child's pulled out drawer.
Fang Zhengjie believes that children's furniture manufacturers may have little knowledge of this standard in our country, and the research is not thorough enough, which leads to some defects in the production design of some specific indicators.
Excessive formaldehyde raw materials are not qualified
According to the national compulsory standards, the formaldehyde emission of children's furniture should be less than or equal to 1.5mg/L. However, in the spot check of the Jiangsu Provincial Quality Supervision Bureau, 71 batches of solid wood children's furniture formaldehyde emission were all qualified, and 60 parts of the plate furniture, nearly 40% of formaldehyde exceeded the standard. The inspectors believe that the main material density board, particle board, large core board, plywood, etc. of the panel furniture are all used in the production process, which is a major reason for the excessive formaldehyde in the panel furniture.
For example, artificial boards are made of non-toxic materials such as natural wood chips, hibiscus and shavings. In the case of plywood, for example, a 12 cm piece of plywood typically requires 3-4 layers of natural wood chips and 5 kg of glue. If there is formaldehyde in the glue, then the board is poisonous. Use these sheets to make furniture, and the furniture is poisonous. Therefore, the fundamental source of toxic substances in home decoration is glue.
The reporter visited the Banqiao Decoration City in Yuhuatai District, Nanjing, and found that there are several kinds of adhesives used in the decoration. White latex, woodworking work in the decoration needs to be used; glass glue, various glass and other substrates The material for bonding and sealing has volatile gas just when it is shot out; 309 glue is used to install natural stone; floor glue is not used much now, as long as the quality of the floor is too good when installing the floor, the lock structure is reasonable. Can not use adhesive; tile adhesive, this kind of glue is the most polluted, generally ordinary ceramic tile construction or sand cement, if you use vitrified bricks need to use such adhesives, there are several commonly known as universal adhesive, there are many uses.
According to Xia Jinyu, an engineer of the Suzhou Quality Supervision Institute, there are many reasons for the excessive amount of formaldehyde emission, which may be due to the lack of quality awareness of the management personnel of the production enterprises, no factory inspection or false factory inspection, and no formaldehyde. Excessive amounts of emissions are subject to an effective control, but the most fundamental reason is that the company uses unqualified raw materials.
“Especially in terms of toxic and hazardous substances, the yield of formaldehyde emission and heavy metal content of 71 batches of solid wood children's furniture is 100%. And 60 batches of children's homes have 23 batches of formaldehyde unqualified, and 5 batches. The unqualified heavy metal content is easy to cause serious harm to children," Xia Jinyu said.
Some merchants do not have real understanding of the regulations, overreacting, such as the bird of surprise, the hole in the cabinet, the replacement of furniture handles, etc., the reason for these businesses to act in a timely manner is not to protect children, but to avoid products being banned. The loss.
"Actually, this is a problem we have to face in many places. When we are measuring one thing, the standard is often the benefit, not the care of others and society." Xia Jinyu said that these are in the cabinet. The business of opening a hole has neglected a very important problem. Now most children's furniture is made of panel furniture. The treatment of panel furniture and edge sealing plays an important role in controlling the formaldehyde release of such wood-based panels. There are no holes in the cabinet for no reason, and the processing surface is not edge-sealed. The amount of formaldehyde released from the sheet is artificially increased, which is not worth the loss.
So, how to deal with children's furniture that has exceeded the standard of formaldehyde? Xia Jinyu said that it can be handled from three aspects: opening doors and windows to ventilate, opening the drawers and doors of furniture when no one is present, accelerating the evaporation of formaldehyde; using activated carbon or Maya blue to remove formaldehyde, mild pollution can be used Activated carbon adsorption, heavy pollution is best decomposed with Maya blue, because only adsorption is easy to saturate and then release formaldehyde into the air again, causing secondary pollution. "The main thing is to control from the source, try to buy solid wood furniture and safety-qualified products."
Solvent residue is over 100 times higher than the standard
The Jiangsu Provincial Quality Inspection Center also conducted risk monitoring on solvent residues such as benzene, toluene and xylene in furniture that consumers care about but not covered by the current mandatory standards for children's furniture. It was found that more than 40% of children's furniture exceeded the solvent. Relevant regulations for the amount of ink solvent residue limit.
The monitoring results show that there are 56 batches of children's furniture solvent residue exceeding the national standard of 10 milligrams per square meter, the highest reaching 681 milligrams per square meter, exceeding the standard 68 times. There are 30 batches of benzene and xylene residues exceeding 3 milligrams per square meter as stipulated by the relevant national standards, and the highest has exceeded 400 millimeters per square meter, exceeding 100 times.
According to Gu Yonghua, deputy director of the Supervision Department of the Jiangsu Provincial Quality Bureau, solvents such as benzene and xylene are classified as the first type of solvent for human carcinogens according to their toxicity. Excessive amounts of such solvents will cause certain hazards to children in the use of these furniture.
“Now the children's furniture on our market uses paint finishing materials, which is a major cause of solvent residue.†Wang Haoming said that in addition, the thickness of the paint finish has a great influence on the solvent residue. Some solid wood furniture is a layer of varnish, so its solvent residue content is relatively low. Some panel children's furniture, the surface is usually colorful paint, the thickness is also relatively high, so the solvent residue is also relatively high.
According to Wang Haoming, there is also a reason that the surface of the panel furniture is treated with putty, on the one hand, the thickness of the paint is increased, on the other hand, it has a certain adsorption effect on some volatile harmful substances, which also causes a relatively high solvent residue. One reason.
On August 1, 2012, China's first mandatory national standard for children's furniture, "General Technical Conditions for Children's Furniture," was officially implemented, and very detailed regulations were made on the margins and cutting-edges of children's furniture, the limits of harmful substances, and warning labels. For example, the total amount of phthalate in plastic children's furniture does not exceed 0.1%, the limit of free acid potassium in textile and leather children's furniture is not more than 30mg, the decomposable aromatic amine is prohibited, and the migration of children's furniture skin coating is prohibited. Elements such as arsenic, antimony and chromium have a clear limit.
"But like all other standards, if there is no supervision and responsible supervision in place, they can play a very limited role." Wang Haoming said that after the implementation of the "General Technical Conditions for Children's Furniture" was implemented, In terms of results, the situation is not optimistic, and children's furniture that does not meet the regulations can be seen everywhere in the store. "This is our current status quo, the lack of integrity really makes us suffer from the enemy, slow pace, whether it is business, or consumers, have to pay more cost and energy to self-certification, or verification." Wang Haoming said.
According to Gu Yonghua, deputy director of the Supervision Department of Jiangsu Provincial Quality Bureau, 131 batches of children's furniture that were supervised and spot-checked, including children's tables, children's chairs, children's cabinets, etc., qualified 46 batches, and the pass rate was only 35%. The main problems are the amount of formaldehyde released, structural properties, warning signs and heavy metals. Although this is only an ordinary quality spot check and test, the problem of response is not optimistic. Children are the hope of family and society. The care and love of children is the common responsibility of parents and society. All those who should bear responsibility are real. Taking responsibility for each other can ensure the healthy, happy and safe growth of our children.
