Where can I find the text of the national implementation standard for interior wall latex paint and

The national standard has not yet been introduced! Now it's the line mark, you can see which one of the following.

Standard number: JG T 3049-1998

Standard name: Putty for building interiors.

Standard Status: Active.

Promulgating Departments:Ministry of Construction of the People's Republic of China.

Brief introduction: This standard stipulates the technical requirements and test methods for indoor putty such as interior walls and ceilings of buildings. This standard is applicable to indoor putty made of water-soluble resin, water-dispersible resin, filler and additives as the main raw materials.

The state has formulated the corresponding standard, namely GB T9756-1995 "Synthetic Resin Emulsion Interior Wall Coating", the specific technical indicators are shown in the following table: Project Index First-class product Qualified product State in the container No hardness, fast and uniform state after stirring Barrier-free brushing Paint film appearance The appearance of the coating film is normal The drying time is not more than 2h The ratio (white and light color) is not less than Alkali resistance (24h) No abnormal Scrubbing resistance, not less than 300 100 Coating freeze-thaw resistance No deterioration The standard divides latex paint into first-class products and qualified products, where qualified products are the minimum requirements for the quality of interior wall latex paints. Among the eight inspection indicators listed in the table, the ratio, alkali resistance, and scrubbing resistance are the key indicators, so the difference between first-class products and qualified products is also this, from the quality of spot checks on interior wall latex paint in recent years, the unqualified items of unqualified products are mainly concentrated in these three items.

Legal analysis: first-class qualified products: no hardness and fast after stirring in the container state, the construction of the second brush in a uniform state is barrier-free, the appearance of the paint film, and the appearance of the coating film is normal.

Legal basis: Product Quality Law of the People's Republic of China

Article 3 Producers and sellers shall establish and improve the internal product quality management system of wild rot, and strictly implement the post quality specifications, quality responsibilities and corresponding assessment methods.

Article 6 The State encourages the implementation of scientific methods for the management of quality and slag, adopts advanced science and technology, and encourages the quality of enterprise products to meet and exceed industry standards, national standards and international standards. Units and individuals with advanced product quality management and product quality reaching the international advanced level and outstanding achievements will be rewarded.

National implementation standards have not yet been promulgated.

This product is now the enterprise standard adopted by many enterprises.

JG T 298-2010 Putty for Interior (replaced JG T 3049-1998).

1.When the quality of interior wall putty is accepted, it is necessary to see whether there are defects in the base layer. For example, whether there are floating particles, warping and cracks and other problems, at the same time, it is necessary to envy the silver putty to reach a flat state, putty without cracking and other standards, if there are cracks and uneven particles on the surface, it is unqualified.

2.The moisture content of the concrete and plastering layer needs to be less than 10% from the water content, and there can be uneven defects before the turning point of the shed and the wall to serve the phenomenon of cleaning and drumming, and it is necessary to keep the handover position straight, and check whether there is putty overflow when handing over with the wood veneer.

Now decoration is inseparable from interior wall latex paint, we all know that paint is one of the most formaldehyde in the home, so many owners are concerned about the quality standards of interior wall latex paint, let's take a look at the five standards of interior wall latex paint.

Quality standards for interior wall latex paints.

Quality standards for interior wall latex paint: 1. Free formaldehyde.

The free formaldehyde in interior wall coatings is mainly used in additives such as synthetic resin emulsions and antifungal agents, which can ensure the chemical stability of the coating during production and transportation, prolong the storage time of the coating, etc. However, the formaldehyde of free formaldehyde will be released into the environment with the drying of the paint to form a film, if the index exceeds the standard, it is easy to cause indoor air pollution, and when the concentration is high, it can cause nausea, vomiting, coughing, chest tightness, wheezing, emphysema, and even death.

Quality standards for interior wall latex paint: 2. Volatile organic compounds (VOCs).

The content of total volatile organic compounds in interior wall coatings should only be used for the impact on human health and the pollution of the indoor environment during the production, construction and use of the coatings, and the national implementation standard for this is 200g l.

Quality standards for interior wall latex paint: 3. Freeze-thaw resistance.

In the 2008 revision of the "Determination of Freeze-thaw Resistance of Latex Paint", the determination of freeze-thaw resistance of latex paint is 244kb

Quality standards for interior wall latex paint: 4. Washing resistance.

Scrubbing resistance is one of the important technical indicators of interior wall coatings, home life is more likely to stain the wall, good paint can be wiped with water at any time, without being wiped off. The national standard stipulates that the scrubbing resistance is qualified: 200 times; First Class:

500 times; Premium 1000 times.

Interior wall latex paint quality standards: 5, contrast ratio.

The contrast ratio is a test item set for white and light paints, which can reflect the ability of white and light paints to eliminate color or color differences on the substrate, and can also indirectly reflect the amount of paint used to cover the same area of substrate. The lower the contrast ratio of the paint, the worse the product's ability to cover the substrate, the worse the coating effect, and the larger the amount of paint per unit area.

The quality of interior wall latex paint is related to the quality of our home decoration ring cover, so when choosing interior wall latex paint, we must pay attention to understanding the quality of latex paint. The above quality standards for interior wall latex paint and the five standards for interior wall latex paint are briefly introduced here, I hope it will be helpful to you. More information is on Rilong.com, so stay tuned.

1. Check whether the surface of the putty is dry (the putty is not dry, if the paint is brushed, it is easy to crack).

2. Check whether there are cracks on the surface of the putty (cracks must be dealt with in time).

3. Check whether the surface of the putty is flat.

4. Check whether the surface of the putty is smooth.

5. Check whether the handover between the wall and the wall is straight.

6. Check whether there is a clear boundary between the wall and the wood products (if the putty is hung on the wood products by the workers, it will affect the appearance quality of the wood products).

First, the interior wall putty gauge with leakage reed fan - interior wall putty construction specification steps.

1. Base treatment: remove and chisel the peeling, loosening and bulging parts on the wall and other base layers, and remove and sweep away the dust, dirt, splash foam and mortar flow marks and other debris remaining on the surface of the base layer. For the mortar base, it is necessary to carefully check whether there is a hollow drum and cracks, and then use 1::

3. Cement, lime, plaster, mortar, and smoothing all over again. The moisture content of the base layer is required to be below 8%, if the unconditional test can be estimated by the feel, the moisture is too large to be constructed, and the construction must be carried out only after drying, and the yin and yang corners of the wall, the closing parts of the window openings, especially the yin and yang angles, should be handed over and accepted after the inspection is completed, and all the doors and windows of the operation will be protected by plastic sheets and other ways to avoid pollution.

2. Repair putty: use plaster to bump the pits and gaps on the wall and other base layers. The damage, textured surface, wind cracks, joints, etc. are leveled and repaired respectively, and the protrusions are smoothed with sandpaper after drying.

3. The first time full of scraping putty: the first time the putty is scraped horizontally with a rubber scraper, a scraper is immediately followed by a scraper, and the joint shall not be left at the joint.

4. The first time with a rubber scraper transverse full scrape, a scraper plate after a scraper, the joint shall not be left behind, each scraper at the end of the end, pay attention to the clean and neat collection. After drying, use No. 1 sandpaper to polish and polish, smooth and polish the floating putty and stains, and then clean the wall.

5. The second putty is scraped vertically with a rubber scraper to trim the verticality and flatness of the wall. After the putty is dry, use Sona No. 1 sandpaper to grind the floating putty and stains and polish them, and then sweep the wall clean.

6. The third time full of putty: the third time the putty is scraped with a steel scraper for a large area, and the wall and other base parts are scraped and scraped and dried, and then smoothed and polished with fine sandpaper, pay attention not to miss the grinding or grind the putty through, the yin corner should be straight, the yang angle should be square, and the wall and ceiling should be scraped and scraped.

7. Check the completed wall coating, focusing on the yin and yang corners and doors and windows after acceptance.

Summary. Kiss! Hello, happy to answer your <>

Pro, the technical specification for the production of interior wall putty is water-resistant interior wall putty. Precautions for the use of interior wall putty paste: 1 Base treatment:

Clean up the floating dust, oil and other attachments on the base layer, and use the liquid sealing anti-crack agent to anchor and seal the dust on the base surface, so that the liquid is not too thick when rolling. 2. The wall is an insulation layer, try to paste gypsum board or high-strength gypsum interface agent once or twice, and then use gypsum caulk to do caulking treatment. If there is an old putty layer on the wall, it must be cleaned and the base surface treatment must be carried out again.

1. Scope of application: This regulation applies to dry indoor walls, basements, toilets and other wet engineering parts, as well as water-resistant scraping putty used in the initial decoration of residences. It is not suitable for walls of soft materials such as metal and paper products, fabrics, polystyrene, etc. 1) General putty implements the JG T3049-1998 "Putty for Indoor Buildings" standard. 2) Class water-resistant putty implements JG T3049 standard; The implementation of water-resistant putty DBJ01-48-2000 "Technical Regulations for the Application of Water-resistant Putty for Building Interior Walls".
