Non-woven wallpaper really is environmentally friendly?

 

Wallpaper of the usual concerns about whether the problem of environmental protection, to be exact, it should be: whether formaldehyde or formaldehyde emission problems.However, even in the wallpaper is the use of the solvent-based inks, don't be afraid, it evaporate also won't have harm to human body.Especially PVC material, volatile fast.May suddenly come strong excitant odour, however, easily no matter in a few days.

Wallpaper is environmentally based primarily on VOC emission measure

At present, a lot of people on the environmental protection concept is fuzzy, however, it is very necessary to make clear, because only then clearly, all about this things is better.

Building decoration materials of environmental protection in three ways: first, the material itself, whether or not to use too many natural resources;Secondly, material waste, whether can the natural solution to drop (commonly known as: rot);Again, the material in use process, if too much and keeps VOC emissions, if there is a discharge of poisonous substances in the process of solution to drop.

In order to enhance the pertinence, first, in this not do explains, because in fact you are not so concerned about this matter.Now, important to say it is the second.Compare the non-woven and PVC.PVC is chemical products, synthetic resin, is the high polymer, is a petrochemical derivative products.PVC plasticity, widely used, people wear clothing, home microwave oven special bowl chopsticks, etc are all or at least contain PVC material.This material is difficult to solution in the nature, even to use hundreds of thousands of years can make polymer chain rupture, complete solution process.So not environmental protection material.

(commonly known as: non-woven), non-woven paper is a kind of weaving, there is no direction also is warp/weft weaving, structure is relatively loose, can solve more easily in the nature, so relative to the PVC, it is environmental protection material.

The comparison of environmental protection on the basis of these two kinds of material is that they were abandoned after the pollution to the environment or the solution down the material used by how much energy (or called natural resources).

In addition, if you want to speak the purity of material itself, PVC, belongs to the high polymer, is pure;Instead of non-woven material is disorderly, the non-woven is a method of weaving is not material itself.Can be assorted non-woven material.

Third, it is about the VOC emissions.VOC = volatile organic come = = formaldehyde volatile organic compounds, ethyl ether, ethanol, etc, in view of the fact that we care about most is formaldehyde, then Jane called formaldehyde emissions.

This thing is there in wallpaper?Need depending on the specific situation.If all the non-woven material no VOC, PVC material will be?It isn't.

Have a name is water-based ink, ink additives used in the process of coloring is the material such as water and ethanol, environmentally friendly;Still have a kind of ink called solvent ink (commonly known as: oily ink), use of additives in the process of coloring is organic solvent, is volatile organic compounds, formaldehyde, not environmental protection.

For PVC material, because the structure is compact, the short base compounds such as formaldehyde penetration, so chemical compounds such as formaldehyde adhesion on surface of PVC material, it is easy to volatilize, basically volatile completed in a few days.

The evaporation process we call VOC emissions.

For non-woven materials, because the structure is loose, organic solvent can searches into material, chemical compounds such as formaldehyde volatilization process is relatively slow.For the current many manufacturer, especially for big brands, the solvent ink with very few, if any, will also increase link in the process of production, make it can finish VOC emissions in the process of production.

In fact in the process of a family to decorate, most afraid of is not a wallpaper, but a composite plate (not real wood).As composite plate of VOC emissions relatively very slow, need a few months or even years.

Almost all not non-woven wallpaper really give prize

The present situation is: including many store clerk, the boss, will say non-woven fabric is the most environmentally friendly.This I feel very strange.Why do you want to speak like that?Is really do not understand?Still afraid of customer been other wallpaper shop to instill this concept lose business?Or...

All is not!Key is non-woven wallpaper is not expensive raw materials, the craft is simple, advertising to can sell high price again, the biggest profits here.

 

I don't know about other countries, but at least in Europe did not like this.In fact, the world's major brands, whether in fort, YiShi or, exhibition worship palace, really colorful wallpaper, nearly all of PVC fabric.Among them, the Italian exhibition worship palace wall paper, all is deep PVC embossing.

Now, it seems, may be the world only for non-woven wallpaper very enthusiastic in my country, because: once upon a time a few years, gradually non-woven bags in the supermarket don't use plastic bags, non-woven bag is environmental protection bags.Reasoning: non-woven is environmentally friendly.Environmental protection are certainly, and formaldehyde emission was not too concerned about.

Domestic manufacturer like production of non-woven, non-woven fabric, there are technological level, as well as profit driven.

Non-woven fabric is suitable for domestic manufacturer of current technological level (don't need embossing roll, with the printing roller. The surface of the PVC whether deep shallow embossing embossing need embossing roll, embossing roll cost is large, laser engraving embossing roll production costs in China is twenty thousand yuan, manual sculpture that is even more expensive. In Italy and Germany, a hand-carved embossing roll, often need to hundreds of thousands of euros, very delicate, art).Because of this, the craft good on the surface of the PVC wallpaper need very large upfront costs.

One thousand market recognition is not high, embossing roll inputs will drain, the risk is very big.And non-woven fabrics using a printing roller as long as more than one thousand yuan, small investment, quick effect, failed to throw away after also not too bad.So the domestic manufacturer is willing to produce non-woven wallpaper.Seems to strictly carry out the policy of the "rapid spike".

Actually, non-woven materials have two defects: first, on the coloring, always a bit of gunk, because non-woven material surface is not dense, the color to penetrate.Second, use oily ink, oily ink additives will penetrate into the non-woven material, formaldehyde is difficult to release.

Test method: rather than ask.But the non-woven fabric prices artificially high, it's good?Theory of expression, both in color and surface technology, are less than PVC.Is, in fact express the feeling of restraint and quiet, non-woven fabric is a good choice.Have a lot of guests specified to non-woven, non-woven exactly good?Whether you need the metope of feeling?

As for the permeability, the key is to clear up to metope ventilation or air.People breathe freely, window, rely on the air.Breathable, metope wallpaper will certainly moldy.Explanation: the back cover or varnish, metope USES basement membrane wall filters through the impurities are not, that is to say, metope itself is airtight.In addition, non-woven wallpaper the bottom surface layer (not) to do is good, on the wall will be break, that's all.

Used as wallpaper of non-woven fabric is the price of raw materials: about thirty thousand yuan a ton, Austin and Germany dragon imported non-woven raw materials is forty thousand yuan per ton.A roll of 5.3 square meters of non-woven wallpaper, the weight at about 1 kg.

That is to say, the cost of one kg per roll non-woven wallpaper 40 yuan.On the loss in the process of production, the cost of a roll of not more than 50 yuan of money.So taobao non-woven 70 multivariate money now a roll of non-woven wallpaper (one kilogram, even is the surface material such as foam or flocking to weight, not the weight of non-woven material) can also provide package mail service, cause it's right here.
