How to choose a Safety Flooring?
Safety Flooring There are four common flooring: solid wood flooring, parquet, laminate flooring and bamboo flooring. Recently concerned about the safety of the floor, mainly refers to those who formaldehyde emission exceeding the enhanced composite safety floor. How to choose a Safety Flooring?
Safety Flooring The quality of the floor on the market uneven, how to buy safe and safe and safe Safety Flooring? A time for consumers to painstakingly, the Internet also came a simple method of formaldehyde: "take a small sample, go home in the water soak for 3-5 minutes, smell a smell of no stimulation. Good security floor Due to lower formaldehyde release, generally do not smell the pungent odor.If you smell the more exciting smell, and even the eyes feel uncomfortable, the basic can be identified that the safety of formaldehyde on the floor exceeded.
This is a reliable method of measuring formaldehyde? Jiangsu Provincial Quality Supervision Institute Chemical Building Materials Center expert Gan Chao said that there are certain basis but the test results are not reliable. "Formaldehyde dissolved in water, its aqueous solution is formalin." Gan Chao explained that formalin will be exudes a pungent odor, formaldehyde over the floor of the floor soaked in boiling water is a stimulating smell. But this test method is very rough, irritating odor may not represent the floor of formaldehyde exceeded, may be the kind of floor formaldehyde emission below the critical value, is still qualified,
Formaldehyde GB inspection shall be carried out under the specified conditions, the procedures, tools, environmental conditions and inspection personnel and other demanding. Such as formaldehyde test extraction method, dryer method, the public self-test is unlikely to meet these conditions, with the online legend of the detection method is also difficult to play a reference role.
"Poison" floor formaldehyde from where? With glue lead to excessive formaldehyde
Mainly refers to those who strengthen the formaldehyde emission of reinforced composite flooring, laminate flooring generally consists of four layers of structure, Safety Flooring surface is wear-resistant layer, mainly composed of aluminum oxide, a strong wear resistance and hardness. Followed by a decorative layer, which is a layer of paper impregnated with melamine resin. There is a grass-roots level, the main structure is high-density fiberboard, the high temperature, high pressure and gluing treatment. Finally, the balance layer, it is a layer of kraft paper, have a certain strength and thickness, and dipped in resin, play a role in moisture deformation of the floor. Solid wood composite board to plywood as the substrate, the board will be bonded together.
Strengthen the floor and solid wood flooring through the adhesive bonding, will produce formaldehyde, less adhesive, the floor drain performance is poor; more formaldehyde, the higher the bonding fastness, the floor containing formaldehyde itself is inevitable. Gan Chao said, "floor production commonly used is urea formaldehyde and phenolic plastic, phenolic formaldehyde content is low, but the price is high." Production enterprises used in the quality of the glue is uneven, poor quality glue will produce formaldehyde emission exceeded The floor.
