National standard is the minimum requirement for the quality of a product. The national standard to be implemented for putty products is "JG/T349-1998 Putty for Building Interior". Generally, the words of national standard are marked on the packaging of qualified products.
2, ISO certification
ISO certification mainly refers to ISO91-2 quality system certification, and the quality of products produced by enterprises that have passed ISO certification can be guaranteed.
3. Look at the anti-counterfeiting
Manufacturers of brand putty powder generally have strong anti-counterfeiting awareness. In order to prevent products from being counterfeited, anti-counterfeiting measures are taken. Anti-counterfeiting signs or digital anti-counterfeiting stickers are generally attached to the product packaging, and the authenticity can be identified by scraping the coating and calling.
4. Choosing brand
Choosing well-known brand putty with high market share is the guarantee of product quality, while the uneven product quality of unknown brands is not guaranteed.
5. Look at the packaging. Generally, shoddy small enterprises have no awareness of "reaching the standard", and you will not find the words "JG/T349-1998 Putty for Interior Use in Buildings" after searching the packaging of their products. Only by looking at this, a large number of fake and inferior products can be excluded.
6. touch the template. The sample can let you see the product effect more intuitively. Wipe it with your hand and draw it with your key, and you can feel what grade the product is.
7. To report. The inspection report of the product can best explain the quality of the product. At present, the putty product has not been exempted from inspection. If the merchant fails to produce the inspection report, most of the products are not up to standard; After you get the inspection report, you should pay attention to whether the relevant indicators meet the requirements, and pay attention to the date when the report is issued. If it is more than one year, it will also be an invalid report that will be automatically invalidated.
8, environmental protection requirements-ten ring certification!
Although putty is generally composed of inorganic powder, we should take care of environmental protection in order to use it safely.
At present, there are many kinds of popular environmental protection standards in the market, which are true and false, and are mixed. It is really not easy to choose a "green product". How to identify it? In fact, it's very simple: the state expressly stipulates that only products that have passed the "ten ring Certification" of the Environmental Protection Administration can be called "green products". In other words, only "ten ring Certification" is the most reliable certification. If manufacturers produce other green product certifications, consumers should be careful, and maybe there is something "fishy" inside.
9, health requirements-pollution control! "Decoration pollution" is not only terrible, but also difficult to prevent. Even if each product can meet the environmental protection standards, ten products piled together in the house are not environmentally friendly, which is the so-called "cumulative effect".
