Electronic corrosion

Electronic corrosion 
     Electronic corrosion in the pulp and paper industry is a significant problem due to the harsh, humid, and chemically-laden environment.
     This corrosion can lead to equipment failure, increased maintenance, and costly downtime. 
   Factors like moisture, corrosive gases (e.g., sulfur oxides, chlorine), and airborne contaminants contribute to this issue. 

Causes of Electronic Corrosion:-

Moisture and Humidity:
    High humidity and condensation accelerate the oxidation of metals and the corrosion of electronic components.
Corrosive Gases:
   Gases like sulfur oxides, chlorine, and hydrogen sulfide react with metals, forming corrosive compounds that degrade electronics.

D
    Dust, dirt, and other airborne particles can contain corrosive substances or retain moisture, further promoting corrosion.

Poor Storage:-
    Inadequate storage of electronics in damp or corrosive environments can accelerate damage. 

Specific Examples:-
Silver Tarnish:-
   Silver, commonly used in electrical contacts, can tarnish due to sulfur compounds, reducing conductivity. 

Copper Corrosion:-
    Ammonia and alkaline compounds can corrode copper, especially at high concentrations and humidity. 

Acidic Conditions:-
   Bleach plants in pulp mills, using strong oxidants like chlorine dioxide, create highly corrosive acidic conditions. 

Consequences of Electronic Corrosion:-

Equipment Failure: -
  Corroded components can fail, leading to production interruptions.

Increased Maintenance:-
 . Corrosion necessitates more frequent maintenance and repairs.


Equipment failures and maintenance can cause costly downtime. 

Corrosion Prevention Strategies:-

Environmental Control:Dehumidification: -
   Reducing humidity levels can significantly slow down corrosion.
 
Air Filtration: -
Removing corrosive gases and particles through filtration systems can protect electronics. 

Material Selection:-

Corrosion-Resistant Materials: -
    Choosing materials like stainless steel or using protective coatings can help mitigate corrosion. 

Protective MeasureAs:-
Conformal Coatings:-
 . Applying thin, protective coatings to circuit boards can shield them from corrosive agents. 

Potting and Molding:,-
   Encapsulating components in protective materials can prevent moisture and contaminants from reaching them. 

Proper Storage:-
Storing electronics in controlled, dry environments can minimize exposure to corrosive elements. 

Regular Inspection:-
Periodic inspection of electronic equipment for signs of corrosion can allow for timely intervention.

Solar Generation in Night hrs

How to get get Solar generations in Night        While standard solar panels cannot generate electricity at night,     New technologies are being developed to address this limitation.      These advancements focus on harnessing the earth's heat or using infrared radiation emitted by the Earth to generate power, potentially creating 24-hour renewable energy sources.  Key Concepts and Technologies :- 1) Anti-Solar Panels (Thermo-radiative Cells):- How they work:-    These panels, also known as thermoradiative cells, work in reverse of traditional solar panels. Instead of absorbing sunlight, they emit infrared radiation into space, which is then converted into electricity.    Nighttime energy:-     They can generate electricity from the difference in temperature between the panel and the surrounding environment, essentially converting the heat escaping into space back into usable power.  Potential:-  ...

Hydrogen at home — It's the end of solar and wind power

  Hydrogen at home — It's the end of solar and wind power         Statement "1000 pounds" per day of hydrogen at home — It's the end of solar and wind power in the world" is not accurate.     While hydrogen can be produced from renewable energy sources like solar and wind power, it's not a replacement for those sources themselves. Hydrogen production via electrolysis, using renewable electricity, is a promising avenue for decarbonization, but it doesn't negate the need for solar and wind power as direct energy sources.  Cause behind its is as under. Hydrogen as an Energy Carrier:-     Hydrogen is an energy carrier, meaning it stores energy produced elsewhere (like from solar or wind) and can be used to power fuel cells or for other applications.  Electrolysis:-     A key method of producing "green" hydrogen involves using electricity from renewable sources (like solar and wind) to split water into hydrogen and oxygen throu...

Lift off the ground during seismic activity, minimizing damage in Japan

Lift off the ground during seismic activity, minimizing damage in Japan     Japan has developed a technology that allows houses to literally lift off the ground during earthquakes, protecting them from damage.    This is achieved using a system of compressed air and sensors that inflate an airbag under the house, lifting it a few centimeters during tremors. The house then gently settles back down when the shaking stops.      Japan has developed innovative earthquake-resistant technology that allows houses to lift off the ground during seismic activity, minimizing damage. This is achieved through systems like the one developed by Air Danshin, which uses compressed air to lift houses on airbags. When sensors detect tremors, the airbag inflates, raising the house a few centimeters and preventing it from shaking violently with the ground.    More detailed explanation: Airbag Technology:- Air Danshin has pioneered the use of large airbags placed b...
