Product Features:

(Orange red; specific gravity: 1.05±0.05; PH value: 1; smell: fresh fragrance.)

It can effectively inhibit the corrosion of copper, iron and other metals, minimize the harmfulness of stress, and have no effect on most coating finishes; there is no harm similar to concentrated hydrochloric acid and concentrated sulfuric acid, and it is safe to use; it has a wide range of applications. It has a significant effect on carbonates, sulfates, rust scars, rust marks and slime.

Scope of application:

The scale, algae, rust and dirt of precision heat exchangers, air coolers, air compressors and air-conditioning devices can be removed; in plastic forming operations, the water pipes in the metal mold and the working oil cooling water pipes can be removed; Thin layer of concrete on the surface of construction machinery and equipment; it can quickly remove water rust on building tiles and mosaics; remove green algae and water rust attached to the surface of concrete sinks and swimming pools; wash copper, Rust, corrosion and dirt on copper alloys, etc.

Instructions:

Heat exchanger and air-cooling equipment: Dilute this product by 5-10 times, inject it into the circulation system and soak for about 1 hour, and then circulate continuously for about 2 hours, and pay attention to keeping the acidity of the circulating fluid at pH 1. After the cycle is completed, drain the cleaning liquid and circulate it with clean water, and then neutralize the remaining acid with QR-124 neutralizer or self-use lye until the pH value of the inlet and outlet water is consistent. The ratio of neutralization with soda ash is: 1‰-3‰

Air-conditioning fins: Use this product to mix with water 5 to 15 times (depending on the degree of fouling) and spray the diluent repeatedly, and rinse with water after the reaction is complete;

Cleaning of metal parts rust scars, corrosion spots and oxide scales: First apply QR-123 stock solution, wait a few minutes, and then rub with a wire brush. If possible, please soak the workpiece directly in the stock solution. After cleaning, rinse with water, and finally dry and apply anti-rust oil.

Precautions:

This product is acidic, please be careful not to touch the skin for a long time

The cleaning of ceramics, marbles and other products should be tried in a small area and can be used with confidence after the safety is proved

This product has an effect on stainless steel, so it is not suitable for long-term soaking
