Which one is Shanghai looking for to treat formaldehyde?

As far as Shanghai is concerned, it is estimated that there are hundreds of companies that control formaldehyde safety, and more will be opened every year. This is a niche industry. Because of the environmental awareness of the owners, no company can be a household name at present, so it is difficult for the owners to choose.

There are hundreds of officially registered environmental protection companies in Shanghai, many of which are part-time. For example, some testing companies also do business in in addition to formaldehyde, and some cleaning companies and decoration companies also do business in in addition to formaldehyde. Most in addition to formaldehyde companies are relatively small. Although the threshold of this industry is relatively low, it can be done with an investment of 654.38+10,000 yuan, but the elimination rate is very high. Maybe the environmental protection company that just served your family will close down next month, which is normal. As for which major, I will provide you with some necessary knowledge points:

I. Business premises:

Go to the door in person to find out whether the company has office space, storefront, etc. Many people flaunt themselves as the designated in addition to formaldehyde company of the world's top 500 companies, and may have their own army without their own offices. It is suggested that customers go to the environmental protection company to find out the scale, service mode and team number of the gas company.

Second, product certification

Understand the packaging and various test reports of in addition to formaldehyde products, such as formaldehyde purification rate, formaldehyde decomposition persistence report, non-toxic and harmless report, etc. It is not excluded that some environmental protection products use three no products or short-term effective products to deal with indoor pollution; The product test report needs to be stamped by CMA or CNAS, and the national building materials testing center or SGS test report is more recognized in China.

Third, the customer case

If necessary, understand its governance case. Many company websites indicate that they were appointed by a large meeting, and most of them are fabricated. There is no website case, and the credibility is relatively low.

Four, standard air treatment contract agreement

Information such as the inspection time after the agreed treatment, the acceptance unit, whether the third party fails to pass the inspection, whether to rework, whether to refund compensation, etc. This agreement is binding on both parties. The owner should cooperate with the environmental protection company to ventilate and close the doors and windows. The responsibility of the environmental protection company is to deal with the promised warranty time. This should be reflected in the contract. I sent the standard template of our contract here, and suggested that the owner can have a look.

Verb (abbreviation of verb) detailed service introduction

Although in addition to formaldehyde is a service industry, details are also important. What links should be paid attention to before, during and after construction? I will introduce the details of our in addition to formaldehyde to the owner here for your reference only.

Sixth, the principle of purification

It's better to demonstrate the process of in addition to formaldehyde in kind, such as the decline of formaldehyde data in the experimental box. Some environmental protection companies have been doing it for several years and still don't know the principle of in addition to formaldehyde. It is taken for granted that in addition to formaldehyde, there are products that penetrate into the plate and react with formaldehyde. Actually, it's not. Most furniture surfaces are either painted or coated with adhesive tape and melamine. These are airtight except formaldehyde potion. The real in addition to formaldehyde principle, in popular parlance, is to make a coating on the surface of furniture, and some coatings are closed. This is not recommended, because the sealant is easy to fall off on the smooth surface of furniture in the later stage, and the sealant can only be used in particleboard, multilayer board, density board and other parts. Without skin, it forms a seal after brushing your teeth. It is normal for in addition to formaldehyde drugs to adhere to the surface of furniture, and the coating on this surface is like a defensive net. Formaldehyde is released, and most of it is absorbed and decomposed by this coating, so the formaldehyde content in the air is obviously less. There are many principles of in addition to formaldehyde, most of which still need to contact with free formaldehyde to decompose. At present, the technology of beating cattle across the mountain is still relatively few. In addition to formaldehyde's technical types also include chitin, photocatalyst and biological enzyme. There is no comparison here. As long as it can solve the problem, it is a good product. Sometimes, after a good product reaches the hands of inexperienced construction workers of environmental protection companies, the effect will be discounted. The place where re-spraying is carried out is small, and the place where it should not be sprayed is hard, which wastes products and has poor effect.

Seven. terms of payment

Because there is a contract, don't worry too much about this. Pay 80% on the day of normal construction and 20% after re-inspection. You can also pay through a treasure, and it is safe to confirm the receipt after the data is qualified;

Eight, maternal and child level in addition to formaldehyde (IQ tax)

I am often consulted by clients. Can it be done at the maternal and child level? I didn't understand it at first, but later I searched online and found that many environmental protection companies said that they could achieve the maternal and child level, that is, the formaldehyde was within 0.07 or 0.08. If the furniture of the owner's house is not very bad, it is possible to achieve 0.03. Why 0.08? At present, there is no maternal and child level standard in China, which is mainly based on national air testing standards. If this data is within the standard, it is safe, not 0.0 1-0.02 lower than the national standard, it is the mother and baby, which is nonsense. At present, the statement that the maternal and child level is relatively standardized still involves false propaganda. It is not recommended that environmental protection companies publicize so much. If you add the word mother-infant level, the charge per square meter will double. When signing the contract, the owner is advised to refer to the national standard. Of course, you can also agree with the environmental protection company that the formaldehyde data must be within 0.07, and you are willing to pay more, which is what you are willing to do. And we only promise to reach the national standard, and 90% of our customers can achieve it within 0.07, so this agreement is actually of little significance.

9. Cheap goods are not good, and the service is not good.

Don't pursue too cheap governance. Cheap goods are not good, except formaldehyde. Don't force in addition to formaldehyde companies to do what they can't do. For example, the national standard for formaldehyde data is closed 12 hours, and formaldehyde is 0. 1 mg per cubic meter. When you asked for less than 0.03, in addition to formaldehyde Company casually agreed. This is unreliable, and it is technically difficult to achieve less than 0. 1. Your unreasonable request, apart from the casual consent of the formaldehyde company, may itself explain the problem.

X. price reference

No profit and no service: What is the general price in in addition to formaldehyde? The low-end 10- 15 yuan; Mid range 30-60 yuan; Slightly expensive RMB 60- 100 per square meter. Based on a house with a square meter of 100, at that time, in addition to the price quoted by the formaldehyde company 1500, the owner had to settle the accounts by himself, and the labor cost was 2-3 times, almost 1200- 1400, and other expenses were about 50 yuan. Can the purification products from 50 yuan help you deal with them? Therefore, services that are too cheap will always have potential low-quality effects. At present, the mainstream in Shanghai is 30-60 yuan. Because of the different product costs, some in addition to formaldehyde companies have their own R&D capabilities, or sell more products every year, so the costs will be lower and the quotations will be more reasonable. If we choose some imported products, and our own goods are small, 100 square meter, the cost of purified products is about 2000 yuan. Considering the labor cost, in addition to formaldehyde Company must quote 50-60 yuan per square meter, which is also very reasonable. After the project is completed, there will be a profit of 1000-2000 yuan. The following is our company's quotation template, which can be seen by peers and owners, and is open and transparent.

XI。 Warranty time

In fact, the warranty period is embodied in the contract. Why do you want to take it out separately? The formaldehyde release cycle is 3- 15 years, generally only in the first 1-2 years, which is the peak of formaldehyde release. In the first year, if we deal with low data, it will be released later, but the indoor formaldehyde data is still very low, and formaldehyde will only get lower and lower. Because the purified product also has a certain durability, it is guaranteed to be no problem for 3-5 years. We usually sign contracts with customers, and the warranty period is 10 years. Let's just say that there was nothing wrong in the past few years. How can there be problems in the later stage? I have been in this industry for almost 10 years. If I promise the customer a 10 year warranty, I don't think anyone will object. However, the elimination rate of in addition to formaldehyde companies is very high. Some companies that don't pay attention to service quality basically have no recommended customers, and most of them will choose to change careers or close down in about half a year, so the later 10 or 15 warranty commitment is equal to zero.

Twelve, choosing a husband company will be more reliable.

Theoretically, the longer a company exists, the more it is recognized by the market, because its services are recognized by users, and owners can obtain this information by looking at the registration time of environmental protection companies. Of course, it does not rule out that some new environmental protection companies have good quality. This is not absolute. Generally speaking, it is reasonable that so many companies that have passed the market test survive and are recognized by consumers.

Thirteen, how long is the re-inspection cycle?

It is suggested to arrange an appropriate re-inspection cycle with in addition to formaldehyde Company, some of which are 3 days and some are 7 days. If you have enough time, it is recommended to arrange the re-inspection between 15 and 45 days. If the data is still qualified during this time, it is safe to sign in!

The above precautions are also my arrangement for answering users' questions in Zhihu. You can leave a message if you think there is anything that needs to be revised, and I will correct it! To sum up, if the bosses of in addition to formaldehyde Company regard each owner as one of their own, there is basically no disqualification. Good products+professional construction+sense of responsibility+good after-sales service are the necessary conditions for a good in addition to formaldehyde company.
