FAQ

What color is the aluminum foil in the air conditioner?

General evaporator air conditioning machines with a hydrophilic membrane with a hydrophilic outer heating condenser machine, cooling machine with non water condenser

Under what conditions can aluminum foil be oxidized?Under what conditions can aluminum foil be oxidized easily? I mainly want to prevent the oxidation of aluminum foil, how much is it with air humidity, or how much humidity range is not easy to be oxidized?

Aluminum is chemically active and easily oxidized. In air, because of the formation of a dense oxide film after oxidation, it prevents the further oxidation of aluminum. High temperature can destroy the oxide film and accelerate the oxidation reaction.

The process flow of high and medium pressure aluminum foil, the function of the formation section, and the control of the drugs and parameters used

The formation process is:Electrode foil, hydration treatment, initial stage formation, middle stage formation, stabilization treatment, final stage formation, stabilization treatment, final stage formation, two - stabilizing treatment, coiling

The foil or foil can be isolated (or reduced) computer radiation:

The foil or foil can reduce computer radiation.How to reduce computer radiation:1, pay attention to the location of the computer display and indoor ventilation: don't let the computer toward the back of someone's place, because the back of the computer screen radiation is very strong; at the same time, the computer screen can produce a brominated two benzofuran carcinogens, so the best place to install the computer room or ventilation fan.

Why can copper foil and aluminum foil shield electromagnetic signals?

In addition because the copper or aluminum oxidation caused by the contact resistance increases, the long-term use of suggestions for tinned copper foil, shielding effectiveness after 2 years will not fall too much. I have a new measurement of shielding effectiveness of copper foil and tinned copper foil at the beginning are basically the same, 114dB (copper 1GHZ) and 112dB (tinned copper 1GHZ). The shielding effectiveness of one year after the 84dB (copper 1GHZ) and 110dB (tinned copper 1GHZ). The effect is really bad.

Battery why aluminum foil as anode, copper foil as negative electrode?

In addition to stability, it is necessary to consider the conductivity of the material, whether it can be machined thin, as well as mechanical strength, cost and other factors. Finally chose Cu and Al.

What size is the aluminum foil bag?What are the commonly used sizes?

Aluminum foil bag, also known as "anti-static aluminum foil bag", "pure aluminum bag."". Appearance: opaque, silver gray.

When installing gas water heater in our house, the installation master will connect the aluminum foil smoke pipe directly to the smoke exhaust port of the machine, but the Internet says it can not be installed like this. What's wrong with this?

Installation requirements:1, the installation of smoke pipes, the use of random equipped stainless steel smoke pipe, elbow.2, when the smoke pipe needs to be lengthened, priority should be given to the use of stainless steel smoke pipe or other corrosion resistance, high temperature resistance, fire resistance, no less than stainless steel metal smoke pipe. When no such pipe, can use high quality aluminum foil pipe is lengthened, but directly with the machine exhaust port connecting bend must use the elbow were equipped with, will never allow the use of aluminum foil and the smoke pipe is directly connected with the exhaust port machine.3. The outdoor part of the smoke pipe must be made of stainless steel smoke pipe which is randomly equipped. The aluminum foil pipe shall not be allowed to be extended directly outside.4, smoke exhaust pipe should be insulated from the ceiling more than 50mm.5, smoke pipe connections must be sealed with aluminum foil tape, and sealed tight, to prevent leakage of smoke.6, the smoke pipe extends outside the glass hole wall and the hole must be sealed, and extends outwards the smoke pipe should be down 3 degrees -5 degrees, the smoke pipe and the glass wall or clearance must be sealed to prevent water intrusion, gas flow.All the service personnel should install according to the requirements, otherwise, the headquarters will check the outlets in accordance with the non-standard installation and deal with the serious network breach and freeze the expenses.Below are typical correct installation plans. Be sure to pay attention to avoiding minefields!
