With the increasing popularity of air conditioning, people began to pay attention to the health problems in the use of air conditioning. Because the indoor unit of air conditioner will inhale a lot of dust and bacteria to stick to the filter screen and evaporator when it is working, and the evaporator is a hotbed of bacterial reproduction, which means it is the most suitable place for bacterial reproduction. After a long time, the indoor air quality will decline, and there will be peculiar smell, which will make people feel irritable and weak. This is what people often call "air conditioning disease". Solving this problem is simple, as long as the indoor air conditioner is cleaned regularly. Simply cleaning the filter screen can not be completely cleaned, and the key part is under the filter screen. In view of the above problems, after repeated research and experiments, our company has produced a household air conditioning cleaning agent which is very suitable for family self-cleaning. How to use the wall-mounted air conditioner: 1. Cut off the power supply and open the indoor panel of the air conditioner; 2. Pull out the filter screen and rinse it with clear water; 3. Aim the cleaning agent at the evaporator (that is, spray the aluminum sheet behind the filter screen until there is uniform foam on the surface of the evaporator, and keep it for 15-20 minutes until the foam disappears automatically, indicating that the cleaning is completed; 4. Replace the filter screen, cover the panel, connect the power supply, turn on the air conditioner, and set the dehumidification state to run for 15 minutes to complete the cleaning. Usage of cabinet air conditioner: cut off the power supply, remove the air intake grille, remove the air conditioning panel, and remove the iron plate to expose the evaporator. Just use it according to the cleaning method of wall-mounted air conditioner. Note: 1. Do not spray electrical components and circuit boards; 2. Stay away from the fire source, avoid direct sunlight and throw into the fire; 3. Keep away from children to avoid injury. (3) the supply of central air conditioning pipeline scale remover.

Attending Rust Inhibitor Features: This product can be directly coated on the rusted steel surface, transforming loose rust into a stable polymer net substance, firmly adhering to the steel surface, forming a protective sealing layer, enhancing the corrosion resistance of steel, and replacing the antirust primer. The coated steel has no influence on the welding quality, and the pungent smell is small during gas cutting welding. Using this product, the derusting process can be omitted, and the coating area is about twice as large as that of the general antirust primer. Scope of application; This product is suitable for ordinary hot-rolled carbon steel parts, and other steel parts should be used with caution. This product is suitable for the corrosion state range of A, B, C and D in SIS standard. Technical performance: This product is produced according to the standard Q/WSH0 1- 1999, and its technical performance is as follows: color reddish brown viscosity 15-25 second specific gravity1.01.02 solid content \ The rust Bo Tu is light, and the rust is thick and thick, which can't be missed. If there are obvious brush marks and pinholes, they should be repaired in time. If there are white bubbles in the coating, it should be wiped off immediately with cotton yarn, and then lightly wiped with cotton yarn dipped in a small amount of alcohol to reduce the acidic substances left on the surface without affecting the antirust quality. This product is not suitable for construction in rainy and snowy weather, so as to avoid getting wet within 24 hours. If white powder appears when wet, it can only achieve the purpose of rust removal. After natural drying for 24 hours, it must be repainted. For the steel surface that originally needed to be coated with two anti-rust primers, one anti-rust primer can be subtracted after coating this product. The antirust effect of this product is good when used alone (it has antirust effect in a short time), and its antirust effect can only be fully exerted when used in combination with other paints. It is best to use it with antirust primer, and the matching paints: all kinds of red lead primer, grease paint and alkyd resin paint are the best. Generally with asphalt primer, generally with epoxy resin paint, pay attention to chlorinated rubber paint, it is forbidden to use inorganic zinc-rich paint. ⑾ Product introduction of special hard film antirust oil for steel pipe This product is made of petroleum solvent, polar film-forming substance, plasticizer and various high-quality antirust agents.
