Paint as a necessary material for decoration everyone should know it! Paint used to be called paint. The main components of coatings are resin, or oil, or emulsion-based, with the continuous development of the decoration industry in recent years, the demand for coatings is constantly growing, but the demand is also brought about some problems, that is, the formaldehyde problem in the paint, we know whether there is formaldehyde in the paint? Next small editor to introduce you to this problem!
Paint contains formaldehyde
paint generally refers to latex paint, latex paint is the main component of acrylic, he is using latex as a thinner, as long as there is glue inside will contain formaldehyde, building materials industry has an old saying "no formaldehyde does not glue", and formaldehyde can increase the service life of latex paint wall and anti-scrub performance. Formaldehyde is a wide range of uses, simple production process, raw materials supply sufficient mass chemical products
. It is the trunk of the downstream methanol product tree, the world's annual output of about 25 million tons, 30% of the left and right methanol is used to produce formaldehyde. But formaldehyde is a low concentration of aqueous solution, from an economic point of view is not convenient for long-distance transport, so generally in the main consumer market near the plant. Import and export trade is also very small. The main methods of methanol oxidation and direct oxidation of natural gas are used in industry. In addition to formaldehyde methods, the actual effect of large differences in the traditional family formaldehyde method, generally through ventilation, placement of green plants, the use of activated carbon, air fresheners and other methods of indoor formaldehyde removal operation, although these methods can receive a certain effect, but and completely eliminate formaldehyde, purifying the indoor environment there is still a certain distance. In particular, the use of some chemicals in addition to formaldehyde, in the process of eliminating formaldehyde, but also will produce some harmful to the human body of chemicals, often not worth the loss, the air caused secondary pollution, the consequences can not be imagined. What's more, the use of vinegar fumigation, grapefruit skin, green tea and other adsorption of formaldehyde, these practices have been proved by experts to have no scientific basis, is ineffective operation.
1, open window ventilation.
2, green plant absorption. Green vegetation adsorption and window ventilation: characteristics, green plant treatment is too small, easy to open windows and limited by climatic conditions.
3, put activated carbon. Active carbon adsorption technology: the use of micro-hole technology to absorb chemical contaminants, formaldehyde, ammonia effect is very good;
4, nano-photocatalytic technology: the use of nano-photocatalytic decomposition of formaldehyde; Nanotechnology catalytic technology is effective and eliminates formaldehyde completely. Defects: Professional deformedehyde removal personnel are required to operate.
5, masking technology (spray, painting): covering the source of contamination; defects: good surface, but formaldehyde is still slowly released.
6, oxidation technology: the use of strong oxidation properties, decomposition of pollution;
7, formaldehyde decomposition technology, the use of precious metal platinum at room temperature to break down formaldehyde into carbon dioxide and water, without any secondary pollution.
8, mineral crystal formaldehyde remover: the use of volcanic rock, bentographic soil, sea foam, bump rod, diatom soil and other pure natural mineral crystals, the addition of nano-titanium dioxide photocatalyst materials and air media and other materials. Eliminate secondary pollution. Safe and effective.
, applicable plant methods to remove formaldehyde
One, hanging orchids
can absorb more than 80% of the harmful gases indoors, the ability to absorb formaldehyde is super strong. General room 1 to 2 pots of hanging orchids, toxic gases in the air can be absorbed, so hanging orchids and "green purifiers" of the United States.
II, tiger tail orchids
leaves cluster, sword leaves just upright, leaves all edge, the surface of milky white, pale yellow, dark green phase, with horizontal stripes. Common family potted varieties, drought-resistant, warm sunshine, but also resistant to yin, avoid flooding. Can absorb more than 80% of the indoor harmful gases, the ability to absorb formaldehyde is super strong.
Thye, Ivy
is the most ideal indoor and outdoor vertical greening varieties, Ivy Vine, branches thin and soft, with gas roots, can climb on other objects. Strong removal of formaldehyde. Can break down two harmful substances, namely formaldehyde in carpets, insulation materials, plywood and xylene hidden in wallpaper harmful to the kidneys.
, aloe vera
perennate evergreen meaty plants, stems short, upright, leaf fat, juicy, needle-shaped. Happy warm, dry climate, cold resistance is not strong, not resistant to shade. It is not only a good hand at absorbing formaldehyde, but also has a strong medicinal value, such as sterilization, beauty effect. Now has developed a lot of potted varieties, with a strong ornamental, can be used to decorate the room.
, tequila
perennational evergreen plants, plants tall, leafy gray-green or blue-grey, the edge of the leaves have thorns, yellow-green flowers. Happy warm, well-lit environment, drought resistance is very strong. This plant is also good at absorbing formaldehyde.
, about paint containing formaldehyde? And the most effective way to remove formaldehyde has been introduced to you. So we later in the choice of paint must choose formaldehyde content is relatively low, so that the damage to our body is also relatively low. There is also that everyone in the decoration of the house when not in a hurry to stay, should be appropriately separated from a period of time, formaldehyde smell scattered in the occupancy. In order to prevent formaldehyde, we can usually keep some plants at home, in order to purify the air, beautify the environment.
