Recent toxic runway incidents have occurred frequently, especially school runway poisoning, which has brought huge trauma to children. Many people began to pay attention to these things and even reconsider whether the plastic runway is safe. As a manufacturer of plastic track materials, I am very uncomfortable with the production of inferior plastic runways. They not only hurt children but also hurt the excellent peers in the plastic track industry. There are many businesses who have joined the industry with their dream of "letting children run." It is by no means a unilateral issue where poisonous runways are poisoned. Qualified plastic track is not toxic Undoubtedly, the most direct cause of toxic runways is material. The main raw material for plastic runways is toxic toluene diisocyanate, which is what we often call TDI. The non-toxic prepolymer after the reaction of TDI and polyether is the material for laying plastic runways. However, when pre-polymerized glues are used, an excessive amount of TDI is generally required, and toxic gases are generated. If these toxic gases are properly treated, they can be converted into non-toxic urea carbon dioxide, which will not harm the human body. Other materials in plastic runways, such as rubber, PU particles, and pigments, are solid objects that will not evaporate, and will not cause harm to the human body. These materials are also widely used in other areas, such as sofas, steering wheels, etc., without technical safety issues. In fact, as early as 2003, there was a large-scale discussion on the safety of plastic runways. The safety issue of the plastic runway has settled in 2008. In order to ensure the safety of the Olympic venues, the experts spent two years on this trial and verification to prove that the plastic runway under the current technology is safe and non-toxic. Since the plastic runway is not poisonous, what are the most frequent toxic runway incidents? Fatal is the low price bidding There are no safety hazards for qualified plastic runways, but inferior plastic runways are not. Low-grade plastic runways use cheap heavy metal driers lead salts instead of more expensive base metals, and toxic phthalic plasticizers are used to enhance runway flexibility. It is well known that lead in heavy metals can rapidly engulf cells after inhalation into the respiratory or digestive tract, invade the bloodstream and cause heavy blood lead poisoning. The overuse of o-phthalate plasticizers can cause boy sterilization. Poor plastic runways can lead to "broken children" and why there is a market because they are cheap! The education department has relevant tender rules: the lowest bidder. It is chilling to think about this policy. The worst consequence of low-price bidding is the vicious bidding of plastic runways. High-quality products are not favored by the market because of the high prices, while cheap and inferior products produced by unscrupulous merchants have become popular. This phenomenon is almost morbid. It has to be said that the "distorted" psychology of the demand market has caused the supply market to desperately meet. The same is because the price is kept down, and the contractor is subcontracting the construction of the runway in order to earn intermediate profits. The actual profit of the lowest construction party is very low. Most of the lowest-level contractors do not have construction qualifications. In order to make profits, they employ the most common construction workers. Do they think that students are poisoned and perfunctory? They also want to make money to support their families, not to mention that they don't understand toxic or toxic. Most of these workers have no culture, and they have not received any special training or experience. The laying of a plastic runway is different from ordinary cement engineering, which involves chemical reactions involving how to control the occurrence of toxic substances and how to perform maintenance and monitoring after the completion of the project. This requires a very professional process. However, under the policy of “low-cost recipientsâ€, professionals are almost laid off and quality products are stocked in warehouses. To ensure the quality of the plastic runway, where can we talk about it? What we need is not only to calm down an incident In fact, every time a toxic runway appears, there are many doubtful points. For example, why poor quality plastic materials can flow into the market? Why did the buyer buy a bad and poisonous product when he patted his head? After the completion of the project, why would the toxic runway be put into use after the completion of the project? If this question arouses, a principal can resign. , even let the education department collectively class. However, in the end, this kind of thing just shovels off the runway, exposing the production business, and then everything is "out of order." So, let the student's poison be "white"? We have a catchphrase called "crime accepted, thoughts are as usual." Every time the school’s “deep†introspection and the inspection of the education department’s “big move†are formal and inconclusive. In fact, these manufacturers are also quite aggrieved. They have even backed off the "relevant departments". Why don’t we question the “exclusive†testing and evaluation of relevant departments and the “tolerance†when reviewing the qualifications of manufacturers, such as the poisonous runway incidents in four schools in Jiangsu, and the manufacturers’ unreliable verification?†Why does the "pseudo" qualification book actually make the head of the education department convinced about this? Why did the runway get used without a test and assessment? Even if there is no interest operation, people like "Ma Daha" should assume responsibility for their dereliction of duty. Responsibility. The "unscrupulous" business was exposed, and the toxic runway was a scoop. Then the future of the poison runway was not a day or two. The handling of the incident has always been a temporary solution, and the education department should re-examine its own tendering standards and formulate a serious accountability system. The authority of the plastic runway industry should establish the industry's testing standards and strengthen the safety testing before it is put into use. At the same time, the plastic track industry should also join forces to establish industry norms. If the fundamental thing is not to be controlled, then someone will escape responsibility, and someone will take risks for profit. Ms. Soong Ching Ling once said: “Everything is for children and everything for children.†For more than 30 years, poor quality plastic runways have awakened society’s vigilance again and again. As the education department of the child’s teacher, as a parent’s production business, the children of the day were hurt by us. What faces do we say “everything is for the childâ€? What face is that they say “the sun at eight or nine?†? The article is an independent view of the author and does not represent the position of the blog.
