Clever tips for cleaning the cement of aluminum alloy doors and windows?

1.When cleaning aluminum doors and windows, do not step on the aluminum frame, and do not pull the frame for support. In this way, it is easy to wear out doors and windows or have accidents yourself.

2.Aluminum doors and windows can be dipped in water or neutral detergent with a soft cloth, and do not use ordinary soap and washing powder.

Do not use detergents, toilet detergents and other strong acid and alkali detergents, which will corrode the surface of the profile.

3.Sealing wool tops and glass glue.

It is the key structure to ensure the sealing and insulation of aluminum doors and windows, and if it falls off, it should be repaired and replaced in time.

4.After the rain, the wet glass and door and window frames should be wiped dry in time.

5.The joints of the door and window frames should be checked frequently, and the bolts should be tightened in time to replace the damaged parts. Positioning axle pins, wind braces, floor springs and other aluminum alloy doors and windows.

The vulnerable parts should be checked frequently, and lubricating oil should be added regularly to keep them clean and flexible.

6.In the use of aluminum doors and windows, the action should be light, and the push and pull should be natural; If you find that there is difficulty, do not deadlift and push, and the fault should be eliminated first. Dust accumulation and deformation are the main reasons for the difficulty of pushing and pulling aluminum alloy doors and windows, and it is necessary to keep the door frame clean, especially the cleanliness of the sliding groove.

A vacuum cleaner can be used to suck up the dirt in the trough and the door seal.

7.Frequently check the joint of aluminum doors and windows and walls, if the aluminum doors and windows are loose, it is easy to deform the frame as a whole, so that the doors and windows cannot be closed and sealed. Therefore, the loose screws at the connection should be tightened immediately, such as the loose screw footing, and a small amount of cement should be adjusted with epoxy super glue to seal it.

If it is the cement that has just dripped on the doors and windows, because it has not yet fully set, we can wipe it clean directly with a damp cloth. Or soak the cement with water before using a rag.

If the cement has solidified, in this case, it can be broken off, and the residual cement can be directly removed with a small shovel, paying attention not to scratch the surface of the aluminum alloy.

If the area is relatively large, use a wooden board to remove it first without damaging the surface. Prepare a damp rag and wipe it off gently.

Aluminum alloy window sticking cement removal method: first soak and soak the cement with water, and then treat it according to the situation

1. You can carefully break off the small cement blocks by hand.

2. Carefully remove large cement blocks with wooden boards (the texture of the wooden boards is loose and will not hurt the surface of the aluminum alloy). Then gently wipe clean with a damp rag.

3. The black mark left on the surface of the aluminum alloy is the oxide film of the aluminum alloy damaged by the cement curing, and it is cleaned vigorously with a damp cloth, but it is impossible to remove it completely, and you can buy aluminum alloy paint spraying.

4. It can be plugged and wiped with gasoline, which is labor-saving and will not harm the aluminum alloy. Chemical reagents cannot be used. It will destroy the surface treatment layer of aluminum alloy door and window profiles.

5. Mix hydrochloric acid or phosphoric acid solution and water in a ratio of 1:5 (if the cement is thicker, you can drop some hydrochloric acid or phosphoric acid solution directly on it first) and pour the adjusted person on it, sprinkle it with sawn wood foam, and use a wooden shovel (don't use metal will leave traces, let alone use steel wool balls to brush the pot). When shoveling, you can also use a rag dipped in water to wet the cement slurry.

It's okay to use a wooden shovel to make it a little stronger, and pay attention to cleaning up with the shovel. When you're done, you can wipe it a few more times.

The upstairs gives a lot of good methods, just implement it. Don't use the method of using acid solution - it will cause secondary damage to the aluminum alloy!

1. Hydrochloric acid or phosphoric acid solution and water are mixed in a ratio of 1:5, if the cement is thicker, you can drop some hydrochloric acid or phosphoric acid solution directly on it first.

2. Pour the prepared liquid on it, sprinkle it with sawn foam, and use a wooden shovel (don't use metal to leave traces, and don't use steel wool balls to brush the pot).

3. When shoveling, you can also use a rag dipped in water to wet the cement slurry. It's okay to use a wooden shovel to make it a little stronger, and pay attention to cleaning up with the shovel. When you're done, you can wipe it a few more times.

Soak and soak with water first, and then treat them separately in several situations: 1. Small lumps can be easily removed. 2. Carefully remove the large blocks with wooden boards (the wooden board is loose and will not hurt the aluminum alloy surface).

3. The black mark left on the surface of the aluminum alloy is the oxide film of the aluminum alloy damaged when the cement is cured, and it can only be cleaned with a wet cloth, but it is impossible to completely remove it. The dirty traces are mainly due to the oxidation of aluminum, which forms a protective film on the surface of the aluminum alloy, making the original gloss disappear. The easiest way to do this is to rub it with (e.g. white vinegar, salt) to remove oxides from the surface.

Don't use colored liquids!

After brushing the oil, it can be removed with a wooden shovel for 24 hours, and then wiped clean with a touch cloth.

Questions. What kind of engine oil is better to buy?

Regular motor oil will do.

Questions. We mainly clean it up manually.

OK.

The method of removing the cement attached to the aluminum alloy window can only be slowly moistened with water, and chemical reagents cannot be used.

The main chemical components of Portland cement: calcium oxide CaO, silicon dioxide SiO2, ferric oxide Fe2O3, aluminum oxide Al2O3.

The main minerals of Portland cement: tricalcium silicate (3CaO·SiO2, simplified C3S), dicalcium silicate (2CaO·SiO2, simplified C2S), tricalcium aluminate (3Cao·Al2O3, simplified C3A), tetracalcium iron aluminate.

There are no steps in the specific operation, you only need to pay attention to the fact that if you rub too hard, the surface of the window will be worn out, and you should rub it slowly and hard, and do not use too much force, which will destroy the surface treatment layer of the aluminum alloy door and window profile.

It can generally be removed by wiping with hot water, if it is more serious, you can use a special cement detergent, and then wipe it with a dry towel after wiping.
