What Are the Types of Coil Coating?

图片
  In the mid to late 1930s, Joseph Hunter, the founder of Hunter Engineering, installed the first coil painting line. He used this method to paint the shutters as part of a continuous strip. Later, Hunter Engineering went on to design and build more coil coating lines. It was eventually acquired by the Italian global engineering company FATA Spa, which is known for building coating lines all over the world.   Today, the  coil coating process  offers a wide range of opportunities for the world's coating companies. The coil coating process is like one of those giant printing presses that produce evening newspapers. The process does not stop, it runs at a constant speed and the  metal coils  are constantly spliced together so that the moving web can be infinitely long. Aluminum Coil   What is the coil coating process? According to EN-10169:2012-06, the coil coating process is a method of applying a continuous coating of organic coating material to a rolle...

Function Of Mesh Onion Bags

 Onion mesh bags not only protect the onion so that the onion in the process of transport is not affected by the collision, impact, and other damage, but they're also are some other USES, today I tell you about the  onion mesh bags  of other USES. Mesh Onion Bags Wash dishes and chopsticks Put the fruit net on your hand, then squeeze a little dishwashing liquid on the net (not too much) and wipe the dishes after you wet them. A little dishwashing liquid can make the net cover up a lot of bubbles, the grease in the bowl can be wiped off. Fruit net cover is hollow out, the face that added friction in the process of wiping, the frictional force is big, the foam that produces is more, such dish bowl can wipe very clean, and the essence that uses wash clean is not much also. Filter water for soap Soap used for a long time, the box will often accumulate a lot of water, as long as the fruit net set in the soapbox, and then put the soap on the net set above, the net set can be se...

The difference between sapphire windows, sapphire optical windows and sapphire protective windows

图片
  A window is a parallel plane plate usually used as a protective window for electronic sensors or detectors of the external environment. The windows do not change the magnification of the system. Substrate materials include various sapphire, optical glass, K9, UV fused silica, IR fused silica and calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), germanium (Ge), silicon (Si) and other crystal materials, and provide various optical coatings such as anti-reflection film, high-reflection film, beam splitting film, and metal film. Broadband AR coatings are available in the UV, visible, near-infrared and mid-infrared wavelengths. A window made of a single crystal sapphire material is called a sapphire window. Sapphire window is a generic name, which itself includes sapphire  optical window , sapphire protective window. Sapphire optical windows refer to sapphire window products used in optical applications. Such optical uses generally refer to imaging, detect...

Guide to Choosing Trekking Pole Parts

图片
Originally known as “ trekking poles ” (a more common term in Europe), backcountry skiers and snowshoe hikers have found the added benefit of using poles year-round, especially in the Nordic countries where such activities are a way of life for many people. As pole use grows, people want more than just fixed-length snowsports poles. The demand for multi-section poles that are easy to pack and adjust has prompted manufacturers to develop new designs and production techniques. With three-section poles being offered by ski stores and outdoor specialty stores, pole use went from mysterious to cool. Grips You would think that a grip is a grip, but in reality they are very different. Grips come in different shapes, widths and materials. Quality clubs use three different grip materials or a combination of them: foam, rubber and cork. Dense EVA foam is popular, has good grip when wet, and feels relatively cool in the hand in hot weather. Rubber handles are very durable and grip well in cold co...

Surge Arrester vs Lightning Arrester: Which One to Choose

图片
    Different terms used for  arresters  are sometimes confusing even professional engineers and electricians use them interchangeably. Now let’s discuss all these arresters in details.   Table of Contents   What is a Surge Arrester? What is a Lightning Arrester? Main Differences between Surge Arrester and Lightning Arrester Should You Use Surge Arresters or Lightning Arresters?   Surge Arrester   1. The  surge arrester  will be installed nearer to the equipment to be protected and the transmission tower line enter in to the substation point. 2. It protects against high voltage transient (example: lightning strike on the transmission conductor) typically, it is indirect protection of lightning strikes. 3. It should be installed each phase of the circuit. i.e if you have 2 parallel switch yard then you should install 6 number of surge arrester (first run 3 phase and second run 3 phase) . Lightning arresters   1. The lighting arrester...
