The Personage Inside Course Of Study: Aggrandizement Floor Index Is Not The Higher The Better!
- Apr 07, 2018 -

Recently, the state administration of quality supervision, inspection and quarantine's website of impregnated paper laminating wood flooring products unqualified name and batch, surface wear-resisting, formaldehyde release a quantity to the main cause of unqualified products. Industry personage says, the use performance that strengthens the floor is crucial is unqualified, will affect floor quality directly, shorten the service life of the floor or endanger human health.

Multiple batches of impregnated paper laminate flooring is not qualified.

Recently, the state administration of quality supervision, inspection and quarantine's website about 2017 second batch of household electric washing machines and other 31 kinds of national product quality supervision and spot check, the results showed that the impregnated paper laminated wood floor products, eight enterprise production 8 batches of the product is unqualified, unqualified project mainly for absorbing water thickness expansion rate, surface wear resistance and formaldehyde release a quantity.

The selectived examination in Beijing, Shanghai, liaoning, jiangsu, zhejiang, anhui and other 13 provinces (municipalities directly under the central government), 120 companies producing 120 batches of impregnated paper laminating wood floor products, companies selectiving examination about accounted for 14% of the total number of such products manufacturing enterprises. Results show that the specifications for the nominal one manufacturing enterprise in "812 mm * 136 mm * 12 mm, model for the" 2108 ", the production date/batch number is "2017-04-05" of impregnated paper laminating wood floor, nominal some production enterprise of zhejiang province, specifications for "809 mm * 148 mm * 12 mm, the production batch number is" 2017-01-05 "of the impregnated paper laminated wood floor eight companies such as 8 batches of the product is unqualified.

On August 16, in addition, the Shanghai bureau of quality and technical supervision of the production and sales of impregnated paper laminating wood floor product quality supervision and spot check, the results showed that 40 selectived examination product batch, unqualified four batches. The nonconformance items involved include static bending strength, surface adhesion strength, surface abrasion resistance and formaldehyde emission. Four of the four companies failed to qualify.

Released on August 21, changzhou city pledges inspect bureau official website of the city's 50 floor production enterprise's product quality supervision and spot check results, the results showed, selectived examination 50 batch products, 4 batch unqualified. The main problem is that the surface abrasion resistance and formaldehyde emission project are not qualified.

The wooden floor products of this sampling are covered with laminated paper laminated wood composite floors, impregnated paper laminated wood floors and solid wood composite flooring.

Surface wear-resisting, formaldehyde release amount to become the main reason that strengthens the floor.

"Impregnated paper laminated wood floor", commonly known as "aggrandizement floor" with macerate of layer or one multilayer amino resin, the shop is in particle board, high density fiberboard, such as man-made board base material surface, the reverse side adds balance layer, the front adds wear-resisting layer, by hot pressing, molding of the floor. Strengthen the floor because of its beautiful, wear-resisting, maintain simple, the price is cheap wait for an advantage, become the first choice that many consumers decorate.

According to the recent national quality supervision, inspection and quarantine bureau and local quality supervision department, the results show that the surface abrasion and formaldehyde emission are the main reasons to strengthen the unqualified floor products. According to introducing, qualitative inspect branch of impregnated paper laminating wood floor supervision and spot check the main basis of GB/T18102-2007 the impregnated paper laminated wood floor, the GB18580-2001 "interior decoration decorates material, man-made board and its products in formaldehyde to release a set limit to" standard requirements, such as static music intensity, for laminate flooring product absorbing water thickness expansion rate, the bond strength of surface, surface wear-resisting, formaldehyde release a quantity to test, surface pollution projects such as corrosion resistance.

Fly above the floor ruggie, general manager of introduction, the use of these project is aggrandizement floor is crucial performance, and these aspects is unqualified, will directly affect the floor quality, shorten the service life of the floor, or harm to human health.

Poor quality raw materials and non-standard production process affect floor quality.

The surface wear-resisting is one of the important technical indexes that strengthen the floor. Generally speaking, the higher the wear-resisting revolution and the lower the wear value, the better the durability of the floor. Strengthen floor surface wear-resisting unqualified most reason is to use the material quality not to pass, some enterprises to reduce the cost to use inferior wear-resisting paper or the quality control of wear-resisting paper is not strict. However, the main reason for formaldehyde release is that the rubber used in the production process is not qualified and the formaldehyde release quantity is not qualified, which directly endangers human health.

In addition, if the absorbing water thickness expansion rate of aggrandizement floor is not up to standard, in use process, because of be affected with damp be affected with damp or affected by the temperature and humidity, easy to cause the arch since the floor, to shorten the service life of the floor.

In addition, consumers should be rational when they focus on the indicators that strengthen the floor, not the higher the better.

For example, surface wear-resisting index, it is not to say all floor wear-resisting revolution the taller is better, want the integral effect that needs the floor to achieve when decorating. In accordance with their own use requirements, within the standard range, the family is applicable.
