There are hundreds of officially registered environmental protection companies in Shanghai, and many of them work 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 companies in in addition to formaldehyde are relatively small in scale. Although the threshold of this industry is relatively low, it can be done with an investment of 1, yuan, but the elimination rate is high. Perhaps it is normal for environmental protection companies that have just served your family to close down next month. As for which major, I will provide you with some necessary knowledge points:
1. Business place:
Go to the door in person to find out whether the company has any office space, stores, etc. Many people advertise that they are the designated in addition to formaldehyde company of the world's top 5, and maybe army of one, who doesn't have his own office, suggests that customers go to the environmental protection company site 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 the company's in addition to formaldehyde products, such as formaldehyde purification rate, formaldehyde decomposition persistence report and non-toxic and harmless report; 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 have CMA test stamp or CNAS stamp, and the national building materials testing center or SGS test report is more recognized in China.
third, customer cases
if necessary, learn about the cases of its governance. Many company websites indicate that they were appointed by a large meeting, and most of them are fabricated. There are no website cases, and the credibility is relatively low.
IV. The standard air treatment contract agreement
stipulates the inspection time after treatment, the acceptance unit, whether to reprocess if the third party fails to pass the inspection, whether to refund compensation and other information. 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 it well and the promised quality guarantee time. This should be reflected in the contract. I send the standard template of our contract here and suggest that the owner can have a look.
V. Details of service introduction
Although in addition to formaldehyde is a service industry, details are also very important. What links should be paid attention to before, during and after construction? I will post the details of our in addition to formaldehyde to the owner here for your reference only.
VI. Purification principle
It is best to have physical objects to demonstrate the in addition to formaldehyde process, such as seeing the decline of formaldehyde data in the experimental box, and some environmental protection companies and others. It is taken for granted that in addition to formaldehyde products penetrate into the board and react with formaldehyde. Actually, this is not the case. Most furniture surfaces are either painted, or coated with adhesive paper and melamine. These in addition to formaldehyde potions are impenetrable. The true in addition to formaldehyde principle, in popular terms, is to make a coating on the surface of furniture, and some coatings are closed. This is not recommended, because the sealing agent is easy to fall off on the smooth surface of furniture in the later stage, and the sealing agent can only be used in the parts such as particle boards, multi-layer boards, density boards, etc., which have no skin, and form a seal after brushing. It is normal that in addition to formaldehyde medicine adheres 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 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 include chitin, photocatalyst, biological enzyme, etc. No comparison is made here. As long as the problem can be solved, it is a good product. Sometimes, after the good product is in the hands of inexperienced construction workers of environmental protection companies, the effect will be discounted. The amount of spraying where it is heavily sprayed is small, and the spraying where it should not be sprayed is hard, which wastes the product and has poor effect.
VII. Payment method
Because there is a contract, there is no need to worry too much about this aspect. 8% will be paid on the day of normal construction, and 2% will be paid after re-inspection. You can also pay through a treasure, and it is also very safe to confirm the receipt after the data is qualified;
VIII. Maternal and infant level in addition to formaldehyde (IQ tax)
I am often consulted by customers. Can you achieve maternal and infant level? I didn't understand it at first, and then I searched online and found that many environmental protection companies said that they could achieve maternal and child level, that is, formaldehyde was within .7 or .8. If the furniture of the owner's house is not very bad, it is possible to achieve .3. Why should it be .8? At present, there is no maternal and child level standard in China, and it is mainly based on the national air testing standard. If this data is within the standard, it is safe, instead of being .1-.2 lower than the national standard, it is maternal and child, which is nonsense. At present, the relatively standardized statement of maternal and child level still involves false propaganda. It is not recommended for environmental protection companies to promote it so much. If you add the word maternal and child level, the charge per square meter will be doubled. When signing a contract, it is recommended that the owner still refer to the national standard. Of course, it can also be agreed with environmental protection companies that the formaldehyde data must be within .7, and you are willing to pay more, which is what you are willing to do. And we only promise to meet the national standard, and 9% of our customers can do it within .7, so this agreement is actually of little significance.
9. Cheap goods are not good, so is service.
Don't pursue too cheap governance, cheap goods are not good, and so is in addition to formaldehyde. Don't force in addition to formaldehyde companies to do things they can't do. For example, the national standard for formaldehyde data is closed for 12 hours, and the formaldehyde is .1 mg per cubic meter. You asked for it to be below .3, but in addition to formaldehyde company casually agreed. This is unreliable, and it is technically difficult to achieve it within .1. Your unreasonable request, which in addition to formaldehyde company casually agreed, may indicate that this company does not understand anything.
X. Price Reference
No profit, no service: What is the general price in in addition to formaldehyde? Low-end 1-15 yuan; Mid-range 3-6 yuan; The slightly expensive 6-1 yuan is charged on a per square basis. Calculated by a 1-square-meter house, when the in addition to formaldehyde company quoted 15 yuan, the owner had to settle the account himself, and the labor cost was 2-3 times, almost 12-14 yuan, and the other expenses were about 5 yuan. Do you want to handle it with 5 yuan's purified products? Therefore, services that are too cheap will always have potential low-quality effects. At present, the mainstream in Shanghai is 3-6 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 cost will be lower and the quotation will be more reasonable. If we choose some imported products, and the quantity of our own goods is small, 1 square meters, the cost of purified products is about 2, yuan. Considering the labor cost, in addition to formaldehyde Company must quote 5-6 yuan per square meter, which is also very reasonable, and there will be a profit of 1,-2, yuan after the project is completed. The following is the quotation template of our company, which can be seen by peers and owners, and it is open and transparent.
XI. Warranty time
Actually, the warranty time is embodied in the contract, so why do you 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 you deal with the 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 products also have a certain durability, it is no problem to guarantee 3-5 years. We usually sign a contract with our customers with a 1-year warranty. Let's just say that there were no problems in the first few years. How could there be problems in the later period? I have been in this industry for almost 1 years, and if I promise my customers a 1-year warranty, I think no one 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 don't have customers who are referred. Most of them will choose to change careers or close down in about half a year, so the later 1-or 15-year warranty commitment is equal to zero.
12. It will be more reliable to choose an old company
Theoretically, the longer a company exists, the more it is recognized by the market, because its services are recognized by users, and the owners can check the registration time of environmental protection companies to get this information. Of course, it does not rule out that some new environmental protection companies are of good quality. This is not absolute. Generally speaking, it is reasonable for so many companies that have been tested by the market to survive and have been recognized by consumers.
XIII. How long is the recheck cycle?
It is recommended to arrange a suitable 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 days and 45 days. If the data is still qualified during this time, the check-in is safe!
The above points for attention are also my answers to questions from users in Zhihu. You can leave a message if you think there is any need to modify it, and I will correct it! To sum up, if the bosses of in addition to formaldehyde Company treat each owner as their own, there is basically no unqualified. Good products+professional construction+responsibility+good after-sales, is a necessary condition for a good in addition to formaldehyde company.
