Is there a difference between putty powder and high calcium stone powder?

There is a difference. The composition of high-calcium stone powder is relatively simple, mainly calcium carbonate.

Powder. The putty powder is calcium carbonate and talcum powder.

and quartz sand, etc., for a more delicate feel and easy to apply.

1. High-calcium stone powder is burnt quicklime.

The powder made of ore is referred to as stone powder, which is also called high-calcium stone powder because it contains more calcium. It is widely used in rubber, papermaking, coatings, plastic and aluminum profiles, ceramics, cement, glass, smelting, refractories, medicine, food, daily chemicals, cosmetics, craft buildings, advanced decoration and other production applications.

2. Putty powder is a kind of building decoration material, the main components are calcium carbonate, quartz sand, talcum powder and glue. It is mainly used to repair and level the wall, and lay a good foundation for the next step of decoration (painting and wallpaper).

The difference is very large, high calcium stone powder is very pure, single calcium carbonate powder. Putty powder has many added ingredients, commonly used calcium carbonate, talc and quartz sand, etc., which are composed of base materials, fillers, water and additives.

1. High-calcium stone powder is the powder made of ore used to burn quicklime, referred to as stone powder, because it contains more calcium, so it is also called high-calcium stone powder. Calcium is present in the form of calcium carbonate. That is, the main ingredient is calcium carbonate!

2. Putty powder is a kind of building decoration material, and the main components are talcum powder and glue. Usually there will be a layer of white powder on the wall of a new house - big white, which is made by putty and water.

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.

Which is good to scrape the big white powder and putty powder, the putty scraping is made with glue cellulose and the putty scraped by the big white powder, the putty powder is based on the proportion of the dry powder and water scraping putty, the price of the big white is low, the cost of putty powder is high, the effect is not much, and the putty powder is more environmentally friendly. Scrape putty well. Because the scraping of the white material is simple, the tool is a long rod brush yard pure, to the wall to brush the barrel of white powder, it can not play the role of adding seams to fill the hole, after the white is dry, it is easy to drop the powder and foam, more with the decoration of the ordinary exterior wall.

The effect of scraping putty is not the same, a kind of glue is added to the putty, and the tool used is a scraper, scraping on the wall, which can add joints and fill holes, so that the wall limb mold is more flat, and it is very strong after drying.

We are happy to answer the difference between lime oil and putty powder: putty powder and lime oil have different compositions. Putty powder is a mixed finished product, which is a finished product composed of double fly powder, that is, heavy calcium powder, gray calcium powder, cellulose, rubber powder, etc.

Lime oil is a powder obtained by reacting lumpy lime made of limestone with water, and it will not crystallize when water is added. When using putty forester powder, you also need to add glue and other substances, lime oil can be used with water, but it is more likely to crack and fall off. 2. Putty is a kind of substrate Tongchun chain used for wall repair and leveling, which lays a good foundation for the next step of decoration.

Lime oil can be configured with lime mortar or cement-lime mixed mortar for masonry or plastering works. 3. Putty is divided into two types: interior wall and exterior wall, and the exterior wall putty should resist wind and sun, so it has high gelatinity, high strength, and slightly lower environmental protection index. The comprehensive index of interior wall putty is good, healthy and environmentally friendly, so the interior wall is not used externally, and the exterior wall is not used internally.

Usually putty is gypsum or cement-based, so that the surface is rough and it is easier to bond firmly.

Difference Between Putty Powder and Gypsum Powder:

1. The raw materials are different.

The raw material used in gypsum powder is mainly gypsum, while the raw material used in putty powder is putty.

2. The construction method is different.

When applying gypsum powder, it is necessary to add appropriate additives, so it cannot be used alone, but when applying putty powder, it can be mixed directly with water.

3. The use of liquid fiber is different.

Gypsum powder is usually used to fill the holes, if the surface particles are rougher, then gypsum powder can be used to fill it, while putty powder is mainly used for priming and needs to be used before painting latex paint.

Precautions for using putty powder.

1. When storing, you need to pay attention to placing it in a dry position at home, and you need to pay attention to waterproof and moisture-proof, and the storage time can not exceed 6 months, if it exceeds 6 months, then the effect will be greatly discounted.

2. When carrying out construction, the temperature should be controlled above 0 degrees as much as possible, and when preparing putty powder, it should be adjusted into a paste before use, and it needs to be used within 4 hours to 5 hours to avoid the deterioration of putty powder caused by a long time.

3. Putty powder cannot be used on the same construction surface as some other putty, otherwise it is likely to cause a chemical reaction and form a certain color difference sock dust on the surface.
