Why is the taste of putty powder so big, and what is the quality of putty powder

Nowadays, people think about environmental protection, and then the environmentally friendly decorative materials must have a period of volatile time, some materials are not necessarily not environmentally friendly, and some materials are tasteless but may be highly toxic, gypsum itself is a mineral, and the soil has a muddy smell. After the decoration of anyone's house, after the window is closed, there is a smell when you enter the door, which is normal.

The decoration smells and is psychologically prepared, like paint, glue, etc., but it is a bit unexpected that the smell is so big after scraping. After reading the replies of netizens, I can finally rest assured. Thank you.

The paint and latex paint I use are still good, and the paint and scraper masters who spray paint are also good, and they are also very good communicators. There is not much talk about, not only in this forum, but also about putty powder or gypsum powder (I'm not sure which of the two causes the taste) and the taste. So I wondered

Is it that the students who decorate did not encounter similar problems, or the pollution of the volatile smell of putty powder in the home decoration is nothing, and it can be ignored after a few months. I don't dare to think about it, what if it is still special?

I bought it in a brand store, and it was written *** exclusively, but I didn't find the environmental protection logo on the bag. Because I didn't notice the problem of putty powder or gypsum powder before, it seems that there is little talk on the Internet, I feel that we don't understand, and it should be about the same when I buy it in a brand store, so I ignored it. I open the window every morning and close it at night, so when I enter the door in the morning, the smell is still more obvious when I put my nose close to the wall.

How did you do it? Do you want to leave the windows open day and night? Hopefully as it was said upstairs.

There is a sulfide in the gypsum, which is not so serious, but it is to say that there is no harm at all.

Look at the packaging, carefully check the brand, model, product implementation standard and whether the putty powder is within the shelf life.

Putty products without fixed packaging, unified production standards, and without any production means and quality assurance system. This kind of product is generally used as a handicraft workshop in the user's room, and the construction workers and production workers are all in the hands of the construction workers at will. In this case, the putty is blended.

There is a certain standard for mixed powder (such as putty powder), but it still needs to be deployed on site, and the final product is also non-standard putty (mixing white latex, 108 glue and other chemical fillers, there is no standard for the amount of addition, all depending on the experience of construction workers). This kind of putty, whether it is product quality or protection of people's health, is completely unknown.

Composition:

Putty is generally composed of base material, filler, water and additives.

The binder, also known as the binder, is the most critical component of putty, mainly playing various roles such as bonding. The most commonly used binders for putty are cement and organic polymers, which are divided into emulsions and latex powders. Cement is a binder with good cohesiveness, durability and reasonable cost performance, but it has poor tensile strength and crack resistance.

Organic polymers can be modified and toughened to improve putty performance.

Carefully check the brand, model, product implementation standard, and whether the putty powder is within the shelf life.

Second, look at the performance.

1. Smooth and delicate.

After the putty is sanded, some fine sand marks will be formed, which is conducive to the adhesion of latex paint, but if the sand marks are too coarse, the latex paint is difficult to fill and cover, which will affect the smoothness of the surface.

2. Degree of adhesion.

Good putty powder (water-resistant putty) has a service life of more than 15 years after being scraped on the wall in a normal batch. The service life of general putty powder can only reach 5 years under the protection of latex paint on the exterior wall.

3. Good water resistance.

This is an important sign that determines the quality of the product. Products with strong water resistance not only have good adhesion under mold and moisture conditions, but also greatly contribute to the film formation of the coating itself.

4. Environmental protection.

Putty powder accounts for 80% of the total area of decoration in home decoration, if the environmental protection of the product is not up to par, living indoors for a long time will affect people's physical and mental health.

5. Constructability.

Good products are well constructed, easy to polish, and the batch thickness is not easy to crack.

1.Look at the powder situation.

Inferior putty: Gently rub your fingers across the surface of the sample coated with inferior putty, and your fingers will be stained with a lot of putty powder.

High-quality putty: Gently rub the sample surface of high-quality putty with your fingers, the fingers are very clean, and the putty does not lose powder at all.

2.Look at the putty after being dissolved in water.

Inferior putty: Gently rub the surface of the sample after water flushing with your hands, and your fingers will be stained with a lot of putty that has been dissolved by water.

High-quality putty: Even if you use your hands to rub the sample after repeatedly rubbing the water, your hands are clean.

3.Look at the surface changes after the water is flushed.

Inferior putty: After the inferior putty sample is washed with water, it will quickly appear blistering and peeling.

High-quality putty: Rinse the high-quality putty sample with the same water flow intensity, and there will be no abnormality on the surface of the putty.

4.Look at the surface layer of the cement after drawing.

Inferior putty: After drawing, observe the fracture surface of the putty. The fracture surface of the inferior putty appears on the surface of one of the cement duplexes, i.e. the putty on the cement surface has been pulled out.

High-quality putty: The fracture surface of high-quality putty appears in the middle layer of the putty itself, and the two cement surfaces are still sticky with putty.

How to distinguish the *** bad putty powder? I will teach you to judge from 3 points.

The first point is to take a little putty in the hand, with two fingers to gently grind, if you feel that the graininess is particularly obvious, this kind of putty is not good, our family putty is generally between 350-450 mesh, such fine particles in the hand should be very smooth to the touch.

The second point is to look at the whiteness of the putty after scraping, just after scraping the putty, the wall looks a little dark, and when the putty is dry, the wall should be white, if the wall is dry, it still feels a little deep, this kind of putty is generally not good.

The third is to look at the effect of the wall after polishing, if the wall is polished, it is obvious that there are many scratches on the wall at close range, this putty is not good.

Choose a good putty, want to make the wall look relatively smooth, in addition to good construction, there is another factor, that is, sandpaper for sanding, the commonly used sandpaper sandpaper to 240 mesh, some masters use 180 mesh for good work, which is not right. The larger the number of meshes, the more difficult it is to polish, but the larger the number of meshes, the flatter the polished wall and the more scratches, and the better the effect after brushing the latex paint, so the owner of the heart must see how much the sandpaper used by the master is when polishing the wall in your home.

There are two reasons why the putty scraped by the developer must be shoveled, one is that the original putty is very environmentally friendly, and the other is that the original putty is particularly thick, and the scratches are very obvious when directly polished on the putty, and it is impossible to do a good job with this kind of wall.

Putty powder accounts for a very small proportion of the whole decoration, maybe putty powder does not need the owner to buy, the owner should master these simple methods to judge the quality of your putty, don't be fooled.

Kiss! Hello, I'm glad to answer your questions. The quality of the pro-putty powder is very good and has the following advantages:

1. Durable. Although the wall putty powder on the market is more expensive than ordinary putty powder, the decorative effect and product durability after use are far beyond the reach of ordinary putty. The most important thing is that after scraping the interior wall putty, you can save the cost of two or three or even more rounds of decoration putty.

2. Breathable. The unique whiteness and density of wall water-resistant putty powder make the adhesion of the product stronger and improve the bond strength. The adhesion and coverage rate of the paint per unit area of the wall can save 25 to 30% of the amount of paint compared with the wall using ordinary putty, and it also has a certain toughness and good air permeability.

3. Water resistant. After the wall putty powder is damp, there will be no chalking phenomenon, and the strength of the product is higher than that of ordinary putty powder, and it has strong water resistance. At the same time, in daily use, the coating will not appear hollowing, cracking, peeling, peeling and other phenomena.

4. Environmental protection. Wall putty powder is an environmentally friendly material, will not produce any pollution to the indoor air, if the wall is polluted, you can directly scrub or directly brush the interior wall paint, improve the performance and service life of the coating. Hope mine can help you <>

Do you have any other questions?

The main purpose of putty powder is to fill the pores of the construction surface and correct the curve deviation of the construction surface, so as to lay a good foundation for obtaining a uniform and smooth paint surface. Putty is divided into oily putty and water-based putty, which are used for paint and latex paint construction respectively. There are two types of putty: finished putty and on-site putty.

Latex paint Latex paint is divided into types of paints, paints, and latex paints. The primer plays a closed, isolating role, and the effect of moisture and mildew protection also depends on the primer. The primer is divided from the function of the coating.

Topcoat and primer. Latex paints include latex paints, primers and latex paints, topcoats. Paint is also divided into undersides.

The primer of latex paint is alkali and moisture-resistant, which increases the combination of topcoat and base layer. Because it is recommended to use a primer. The function of the topcoat is to decorate and be beautiful; Latex paint is the name for the two together.

Putty powder is also called dry powder putty, and you can scrape it by adding water directly. Double fly powder needs to be mixed with glue before it can be scraped. The adhesive inside the dry powder putty is a dispersible latex powder, and latex paint needs glue to bond.

From the perspective of environmental protection, the glue contains more formaldehyde and other substances, and the water resistance is also poor.

The difference between this latex paint and putty powder is that latex paint has a sour taste, while putty powder has no taste, so that's the difference between them.
