When choosing home improvement products, which decoration materials should be carefully selected? Recently, the Nanjing Municipal Bureau of Quality Supervision issued a report on the quality of some home improvement pollution source products in 2018.
A total of 125 batches were sampled this time, and the qualification rate of interior wall coatings was 86.
7%; the qualification rate of adhesives was 93.
3%; the qualification rate of diatom mud and wallpaper glue products was 100%; the risk monitoring compliance rate of beauty joint products was 97.
5%.
It is worth noting that in recent years, the highly respected new decoration material diatom mud, although the sampling pass rate is 100%, all indicators have been detected, which means that the material is not advertised as "zero pollution" "Experts remind that consumers should also try to avoid excessive use of such materials, so as to avoid superimposing effects and causing excessive pollution of the indoor environment.
This year, Nanjing Municipal Bureau of Quality Supervision commissioned the National Building Material Product Quality Supervision and Inspection Center of Nanjing Product Quality Supervision and Inspection Institute (Nanjing) to carry out inspections on home improvement products such as beauty joints, diatom mud decorative wall materials, wallpaper glue, adhesives, and interior wall coatings.
Random inspection and risk monitoring.
It is understood that the sources of sampling samples cover manufacturing companies in Nanjing, physical stores of building decoration materials and major mainstream e-commerce platforms.
A total of 125 batches were inspected, including 40 batches of beauty joints, 20 batches of diatom mud decorative wall materials and wallpaper glue, 15 batches of adhesives, and 30 batches of interior wall coatings.
The main test items this time are volatile organic compounds.
Material (VOC) content, free formaldehyde content, benzene series content, soluble heavy metal content, scrub resistance, etc.
The test results show that the pass rate of interior wall coatings is 86.
7%, the unqualified items are scrub resistance; the pass rate of adhesives is 93.
3%, and the unqualified items are free formaldehyde; the pass rate of diatom mud and wallpaper glue products is 100%; Product risk monitoring compliance rate is 97.
5%, and the total volatile organic compound index of unqualified items.
The reporter of Modern Express noticed that the lowest pass rate of the sampling inspection was the interior wall paint.
A total of 30 batches of interior wall paint were randomly inspected this time, 4 batches were unqualified, and the unqualified item was scrubbing resistance.
For example, the performance of the products of Xuanwei and Caizhou brands in this random inspection is far below the national standard.
"Poor scrubbing resistance can lead to delamination and powdering on the wall.
In order to reduce costs, some companies choose cheap emulsions or reduce the amount of emulsion added, resulting in substandard scrubbing resistance.
" Experts said.It should be noted that although the qualified rate of the diatom mud sampled this time is 100%, it does not mean that it is "zero pollution.
" Chen Zhuqing, an engineer from the National Building Material Product Quality Supervision and Inspection Center of Nanjing Quality Inspection Institute, told Modern Express that diatom mud is a dry powder interior wall made of inorganic gelling materials as the main binding material and diatom materials as the main functional filler.
Decorative coating materials.
The main materials of diatom mud products are derived from deep-sea inorganic minerals, which have strong crack resistance and adsorption performance, and are a new type of decoration material that is popular in recent years.
Chen Zhuqing said that in the 20 batches of products sampled this time, the content of all hazardous substances meets the existing relevant standards, but all indicators have been detected, which means that the material is not claimed to be "zero pollution.
" She reminded that consumers should also try to avoid excessive use, so as not to produce superimposed effects and cause excessive pollution of the indoor environment.
When consumers buy products, experts remind that they can ask businesses to provide the relevant qualifications and certificates of the manufacturer and the quality promise of the manufacturer.
Check whether the product packaging labeling is complete.
In addition, the inspection reports of related products of the manufacturer shall be checked, and the actual measurement results in the inspection reports of similar products shall be compared with the technical requirements, and the products with various quality indicators far higher than the standard requirements shall be selected first.
For new decoration products such as diatom mud and beautifying agent, you can also pay attention to the model or sample displayed by the merchant during the purchase process.
For example, high-quality diatom mud wall materials have a soft feel, and inferior diatom mud has a rough and hard feel.
Try not to choose products that are too bright.
Chemical pigments may be added; when the beauty joint agent is opened for use, the smell is generally small.
Aromatic or strong pungent odor, it is possible that excessive additives have been added during the production of the product.
