Please strictly follow the following steps to ensure construction quality and safety. 1、 Preparation before construction
1. * * Surface Treatment * *:
-Thoroughly clean the surface of the metal or old paint layer to be repaired, ensuring no oil stains, rust, moisture, or dust.
-Polish the substrate with P80-P120 sandpaper to enhance the adhesion of atomic ash.
2. * * Materials and Tools * *:
-Prepare Changxing Baodi atomic ash main agent and supporting curing agent, clean scraper, mixing tools, and measuring tools.
2、 Preparation of Atomic Ash and Curing Agent
1. * * Accurate ratio * *:
-The weight ratio of main ash to curing agent is strictly formulated according to 100:1.5-3 (please refer to the product manual for specific ratios).
-Use specialized measuring tools for weighing to avoid proportion deviation caused by empirical estimation.
2. * * Fully Mix * *:
-Squeeze the curing agent evenly onto the surface of the main ash, and stir at a constant speed with a scraper for 2-3 minutes until the color is completely consistent, without stripes or particles.
3. * * Environmental adaptability adjustment * *:
-* * Temperature adjustment suggestion * *:
-Low temperature environment (<18 ℃): Increase the amount of curing agent appropriately (not exceeding 3%) and extend the operating time.
-High temperature environment (>25 ℃): Reduce the amount of curing agent (not less than 1.5%) to avoid rapid curing.
-Suitable construction environment: temperature 18 ℃ -25 ℃, humidity 50% -70%.
3、 Scraping and curing operation
1. * * Scratching points * *:
-* * Operation efficiency * *: After mixing, scraping should be completed within 5-7 minutes (under 25 ℃ conditions).
-Layered thin scraping:
-First step: Fill the deep concave area and use a hard scraper to scrape it thick, not aiming for smoothness but for flatness.
-Second/Third step: Repair sand holes and small depressions, and apply fine scraping with an elastic scraper.
-Fourth step (optional): Dilute the atomic ash and thin scrape the whole to achieve a smooth surface.
-When scraping, keep the scraper tilted at 60 °, squeeze out bubbles, and ensure no pores.
2. * * Curing and Polishing * *:
-Let it stand at room temperature (25 ℃) for 60-80 minutes, and only after confirming complete hardening can it be polished.
-Use P120-P180 sandpaper to polish in the forward direction to avoid scratches.
4、 Key precautions
-* * Safety protection * *: Wear gloves, goggles, and masks during operation to avoid skin contact or inhalation of dust.
-* * Material Management * *:
-The mixed atomic ash cannot be refilled into the original tank to avoid contamination.
-Unused materials should be sealed and stored in a cool and dry place, away from sources of fire and direct sunlight.
-* * Problem Prevention * *:
-Excessive curing agent can easily lead to cracking, while insufficient curing agent can affect adhesion.
-Insufficient drying of primer or residual oil stains on substrate may cause blistering and peeling.
Changxing Baodi Environmental Protection Technology Co., Ltd. focuses on the research and production of environmentally friendly coatings, providing high-performance atomic ash and supporting products for fields such as automobiles and machinery.
