A, decorate the construction method of environmental protection dry powder coating
1. Dry powder spraying shall be carried out within 24-48 hours after the construction of thermal insulation wall covering mortar protective layer is completed.
2, cement mortar wall construction do dry powder coating after 3 days; At the same time, cement mortar plastering is required not to crack.
3. If the base surface is dry, water should be sprayed evenly.
4. Proportion of dry powder coating: dry powder coating: water = 100:20 (weight ratio).
5, the deployment of dry powder coating must have someone who's in charge.
6, dry powder coating in strict accordance with the requirements of water, can't add more water, so as not to produce color difference. It should be used up within 1h after batching.
7. Water is drinking water.
8. Weigh all the water, add it into the batching bucket, pour in about 3/4 of the dry powder coating, and stir it evenly with a portable stirrer (less than 380 rpm), then pour in the remaining dry powder coating, stir it evenly, let it stand for 10- 15 minutes, and then stir it evenly for about 1 minute.
9, dry powder coating construction requirements level off, hair points evenly distributed, each frame ingredients from left to right a continuous plaster hair; Hair in the same direction, hair with plexiglass trowel smooth. Special dry powder coating should be used around the window frame.
10, dry powder coating construction should make a dividing line, to prevent joint scratches, affect the decorative effect.
Second, how to identify environmentally friendly dry powder coatings
(A), the difference between the principles of environmental protection
Principle 1: Nano fumed silica is selected as the main component of inorganic functional coatings, and nano technology is applied to construct micro-batteries capable of generating negative oxygen ions.
Formaldehyde (HCHO)- carbon dioxide (CO2)+ water (H2O)- calcium carbonate (CaCO3)
Principle 2: Purify the air with activated carbon: Use the strong adsorption of activated carbon to adsorb harmful gases in the air.
Difference: Principle 1 can absorb harmful gases such as formaldehyde, decompose formaldehyde and release negative oxygen ions. Principle 2 can only absorb harmful gases such as formaldehyde.
(2) Identification of moisture-proof and mildew-proof performance
Based on ultra-fine porous structure, it can automatically control temperature and humidity, and continuously absorb and release moisture in the air; Effectively improve symptoms such as yellowing, mildew and condensation caused by temperature and humidity changes, and keep the wall as new.
Using the pores visible to the naked eye, just like the principle of sponge absorbing water, it can absorb water, but it can't lock water.
(3) Recognition of vision, smell and touch.
Vision: Through different tools and different construction methods, we can create an infinite variety of personalized decorative effects. The vision is natural, harmonious, non-reflective and non-irritating, which can alleviate the eye fatigue caused by reading books and watching computers for a long time, and can completely replace wallpaper wallcovering.
Smell: refers to the functional treatment of chemical harmful gases such as formaldehyde and ammonia. Really feel that the product brings you fresh, comfortable and assured living space.
Feel: Soft and smooth, non-sticky, more different from latex paint, close to wallpaper wall covering.
I believe that after reading the above contents, you already know how to use and identify inorganic environmentally friendly dry powder coatings! We can ask whether there is a pungent smell when buying inorganic environmentally friendly dry powder coatings, so that we can identify the true and false.
