If you haven't renovated yet, it is recommended to take a month to do your homework, see what pits there are, after so many years, the water in the decoration industry is really deep.
1. It really exists on the market"Formaldehyde-free"Plates?
A: Reveal the time! As beautiful as it sounds, the so-called "formaldehyde-free" panels are not really formaldehyde-free at all. Internationally, there is a clear classification of formaldehyde emissions: E2 level (50 mg L), E1 grade (15mg L), E0 grade (0.).5mg l), these grades of plates are considered environmentally friendly plates. It is important to know that only panels that are at or below E1 are considered to meet the environmental standards for indoor use. The "zero formaldehyde" advertised by some products on the market actually means that no additional formaldehyde is added in the production process, but this does not mean that these boards are completely free of formaldehyde, because the wood itself may contain trace amounts of formaldehyde.
So, when you hear the "formaldehyde-free" propaganda, understand the real meaning behind it!
Second, how to choose the specifications of home decoration and wires?
A: Energy efficient and efficient! Not all corners need 4 square meters of wire, choosing the right size is the key. There are three common specifications of wires:15 squares, 25 parties, and 4 parties. For most home scenarios, 25 square wires are more than enough to use, especially for kitchen and indoor outlets. But when it comes to high-power appliances in the kitchen, such as microwave ovens and ovens, it is recommended to take a 4-square wire to ensure safety and the stability of electricity**.
As for the bathroom, relatively few appliances are used, and the choice of wire can be decided according to the actual needs. If there are no high-power appliances such as electric water heaters installed in the bathroom, then 25 square wires are sufficient. However, if an electric water heater is used, it is recommended to wiring separately and set up an independent circuit according to the power of the electric water heater, considering the safety and power requirements.
In short, a reasonable selection of wire specifications can not only save costs, but also ensure the safety and convenience of household electricity.
3. How long is the warranty period after decoration, and are there any official standards?
A: According to the provisions of the "Regulations on the Quality Management of Construction Projects", residential interior decoration and decoration projects enjoy a warranty period of at least 2 years under normal use conditions. For key projects such as hydropower and waterproofing, there is a longer warranty of up to 5 years. Indeed, there are decoration companies in the market that may promise a long warranty period of 10 years or even 20 years in order to attract customers, but these commitments often lack practical support and guarantee, so when choosing decoration services, it is important to look at the company's reputation and service quality, not just the length of the warranty period.
Write at the end. From the true face of the "formaldehyde-free" board, the wisdom of wire selection, to the true meaning of the warranty period after decoration, these seemingly subtle details are actually related to our future living experience and safety.
