![]() ![]() ![]() It was widely believed that the move to lead-free soldering would create more environmentally-friendly conditions however because of the higher temperatures required and extra flux used lead-free soldering smoke emissions actually contain more fine dust particles which are easier to breathe in. Soldering and rework, like other activities involving adhesives, welding and laser applications, creates particles and gases which can be harmful to workers. Why soldering fumes are a risk to workers ![]() In this article we look at the nature of the risk, the relevant legislation, and how fume extraction can be managed safely, effectively, energy-efficiently and in compliance with regulatory demands. Even in regions without such legislation employers have an ethical duty to provide such protection. Most countries recognize this and enforce legislation to ensure that employers protect their employees from these harmful effects. Employers may face expensive compensation claims as a result. Further hand soldering and desoldering is frequently used in rework stations to carry out repairs and upgrades.Īll of this soldering activity generates fumes which can cause long term, serious harm to operators if inhaled. A small part of the operation is automated, using wave soldering machines, with the majority being manual as operators add individual components using hand soldering irons. Essential considerations for managing soldering fume extractionĮlectronics production is heavily concerned with soldering components on to printed circuit boards (PCBs). ![]()

![]() ![]() The information that is housed in the metadata can be of any type, from the name of the company, to the name of the computer, through tags, modification dates, location, etc. These types of image metadata can be in various formats. Such as the camera with which a photograph was taken or the time it was taken. The metadata of the photographs is extra data that is added to the files. It is available as a Perl library and a command line application. It is independent of the platform we use. This is a free and open source program for reading, writing and manipulating image, audio, video and PDF metadata. In the future to update the tool, users have to simply run the system update command and if a new version is available through the system repository of Ubuntu, it will be installed.In the next article we are going to take a look at ExifTool. We have just given a few basic examples, for more options or parameters to use with ExifTool, you can see the official website of this tool. ![]() You can add multiple keywords by specifying the -keywords+= option multiple times. exiftool -keywords+=landscape -keywords+=nature image.jpg Then the command will be like something below. For example, you want to add two keywords landscape and nature to an image.jpg. If you want to add a keyword to an image then that is possible as well. exiftool -r -overwrite_original -all= directory/ Adding keywords to images: The -r option makes ExifTool process files recursively, and the -overwrite_original option makes ExifTool overwrite the original files with the modified files. This command will remove all metadata from all files in the directory and its subdirectories. exiftool -tagsfromfile track.log -geotag image.jpg Batch processing files: The track.log file must be in GPX format. This command will geotag image.jpg using GPS data from track.log. For example: exiftool -Filesize -MIMEType -BitDepth image.jpg Geotagging images: You just have to specify multiple tags separated by spaces. If you want to see some specific metadata then you can do that as well. exiftool -TagsFromFile source.jpg target.jpg Extracting specific metadata from a file: You can specify multiple source files separated by spaces. This command will copy all the metadata from source.jpg to target.jpg. Copying metadata from one file to another Even, you can specify individual tags to remove by replacing -all= with the tag name, for example: -artist= -copyright=. In the screenshot, you will see it has removed the Artist name and other metadata. The given command will remove all the Metadata information except the protected ones. This Exiftool command will set the artist metadata to “ LinuxH2s” in the image file. To edit metadata in an image file, type: exiftool -Artist="LinuxH2s" image.jpg To view metadata from an image file, type: exiftool image.jpg Exiftool command to edit metadata Note: Change the Image.jpg with your Image or media file name. Run ExifTool commandsĪs you have completed the installation, you can edit the metadata right from your Ubuntu Terminal. Here are some examples of ExifTool commands to follow: It will download and install all the required packages. Therefore, in your command terminal, you just need to run the given command. Installing ExifTool on Ubuntu 22.04 or 20.04ĮxifTool is available through the system repository of Ubuntu and other its based Linux distros including Debian and Linux Mint. Let’s start with the system update because apart from updating system-installed packages, it also rebuilds the APT package indexed cache so that it can recognize the latest available package updates. Ubuntu users can also use the keyboard shortcut which is Ctrl+Alt+T. Go to the Application area or simply click on the Activities taskbar link to search for the terminal app. ![]() ![]() ![]() What are the different types of coolant? What is a coolant inhibitor? While some coolants are compatible with others, changing the chemical balance in the cooling system can affect coolant performance, so mixing different types of coolant is not recommended. Coolant should be changed at recommended intervals because some of the additives will age and deteriorate over time, reducing the effectiveness of the coolant. What types of additives are used in coolants?Ī fully formulated coolant is comprised of a careful balance of ethylene or propylene glycol with rust inhibitors, corrosion inhibitors, scale inhibitors, pH buffers for the acid to alkaline balance, anti-foaming agents, and reserve alkalinity additives. Manufacturers can recommend other specific mixture ratios, but below 33.5% Glycol the coolant will give inadequate freeze protection, and above 65% Glycol the mixture has inadequate heat absorption. This will lower the freezing point of the fluid to minus 39☌ and raise the boiling point to 108☌. A common Glycol to water ratio used is 50:50. Glycol does not absorb heat as effectively as water, but when added to water it has the ability to lower the fluid’s freezing point as well as raise its boiling point. Propylene Glycol, which is non-toxic, is sometimes used in the mixture, as well as, or even instead of, the more toxic Ethylene Glycol. ![]() What is coolant made of? It's just water right?Ĭoolant is normally a concentrate fluid, usually made of Ethylene Glycol together with some protective additives that is mixed with demineralised water to produce coolant. Be compatible with cooling system component materials.Have a higher boiling point and lower freezing point than water.Learn More: How to check your coolant - Click Here.

When an engine stands idle in cold weather, water in the cooling system will expand as it freezes, and this can have sufficient force to crack the engine block or radiator. The amount of heat generated by an engine is the equivalent of that required to heat a large house in winter in very cold climates! As engines and vehicles become smaller and more powerful they generate even more heat in a confined space, and aerodynamically efficient body designs tend to direct air away from, rather than into, the engine bay. Coolant related products:Ĭoolant is commonly a liquid substance that is used in a closed system to reduce and regulate the temperature of an engine. When water starts to boil, it'll build up pressure from the gas expansion in the system causing it to overheat the system and blow vital gaskets. But before that, you will find that water boils at 100c and freezes at 0c, this works outside the optimal range for engine requirements as some engines will heat up over 100c especially on hot days. If you choose to use only tap water in your cooling system, this can cause radiator, head gasket and thermostat corrision damage over time. If you're still not sure, check the owners/service manual for coolant specifications. Most coolant brands will keep their coolants the same colour to prevent any confusion. The most common method to find out is to simply check the coolant and find out what colour it is when the vehicle is cold. If you use the wrong coolant then over time you’ll begin to notice a drop in your car's performance, and can find a significant amount of damage. When it comes to the coolant you must make sure that you’re using the right one. Once this is completed you will be suggested the right products to suit/fit your vehicle while searching our site.

With a few windmills and solar panels, you should be able to build up a sold reserve of power to survive without a problem. Since lithium is quite common on this planet, you should be able to make a lot of small batteries when you are setting up a base on the planet’s surface. This means you will need to use both wind and sun to provide a steady supply of power. If you are relying on solar, the batteries may not get time to fully recharge before night comes.
