What Is The Performance Of The Edge Ladder Related To?
Some insulation ladders have high performance and some have low performance. What is the performance of insulation ladders related to? 1. Material. The insulating ladder with good performance is mainly made of epoxy resin, which has strong toughness, wear resistance, corrosion resistance and long service time. 2. Production process. The high-performance insulating ladder is manufactured by the polymer pultrusion process, and the surface is plated with a protective layer, which is safe and reliable. 3. Maintenance. If the insulating ladder is properly maintained, its working performance can be greatly extended.

Detailed Explanation Of Heat Treatment Process Of Aluminum Alloy Telescopic Ladder Bushing
The shaft sleeve is one of the main parts of the gear pump, which is installed at both ends of the high-speed gear to support the bearing. It must have sufficient strength and good abrasion resistance. In order to ensure the performance requirements of the parts, our factory uses non-standard aluminum-tin alloys, and the role of Cu is to strengthen the matrix. Sn can form a softer, low-melting Al-Sn eutectic, which increases wear resistance. The original heat treatment process is water cooling at 515°C for 6 hours, and air cooling at 180°C for 8 hours. There are two problems with this process: (1) The Al-Sn eutectic was overfired and tin was added to form an Al-Sn eutectic containing 99.5% tin, and the melting point was 229°C. When the workpiece is heated to 515 °C, the Al-Sn eutectic is overfired, and remelted pellets are formed during quenching and cooling. In the process of forming remelting pellets, on the one hand, the grain boundary is oxidized, which reduces the strength of the grains, and on the other hand, many microscopic voids are generated, which increases the grain interface energy and reduces the strength of the metal, which is easy to pass through during use. early failure. (2) The production time of the process is long, up to 16h, the production efficiency is low, and the energy consumption is large. It can be seen from the metallographic observation and mechanical property test data that the 250℃×7h treatment process is ideal. The Al-Sn eutectic is distributed along the grain boundary in a broken network. On the one hand, the distribution of the Al-Sn eutectic is relatively uniform, which ensures good wear resistance. On the other hand, the Al-Sn eutectic does not divide the matrix, so that the alloy has better plasticity and toughness. The higher hardness can be obtained by the treatment process of 250℃×7h, because the alloy contains less Cu and the cooling speed of the metal mold is fast. During the cooling process of casting, it has been

What Are The Steps To Safely Use An Insulated Joint Ladder?
The insulated joint ladder is a tool used in electricity. Although its use method is simple, there are still workers who have accidents during operation. Let me tell you about the three steps to safely use the joint ladder. Insulated Joint Ladder Step 1: Before using the insulated joint ladder, first find a good working environment. If it is outdoors, it must be in suitable weather, heavy rain, heavy fog and other conditions. Step 2: Check all parts of the joint ladder, whether the parts are damp, whether the side connections are firm, whether various accessories are loose, etc., to prevent accidents. Step 3: When using the insulated joint ladder, one person climbs, and the rest hold the feet of the ladder to prevent falling. When we use the insulated joint ladder, we can follow the above three steps to ensure safety at work.

How To Distinguish Between Safety Ladders And Ordinary Ladders
In daily life, when most people have climbing needs, such as: decoration, high-level cleaning, file access, the most commonly used climbing tools are ladders. Ordinary ladders are nothing more than wooden or bamboo, that is, they are not heavy or heavy. It saves space and is very troublesome to store. It cannot be placed in the office and living environment. Moreover, after a long time of placing natural organic materials, the load-bearing performance will be reduced, and the structure will be deformed, which will bring great hidden dangers to safety. , many people usually put two chairs or stools together instead of a ladder for the sake of convenience. This is very dangerous, whether you believe it or not, according to the survey results of the American labor organization, even American workers with professional equipment, in Forty-five percent of the causes of work-at-height accidents are caused by ladders. I want to see the movie "Death is Coming", and I will know that there are all kinds of traps and crises in our daily life. If you are not careful, you may pay the price of your life. This is definitely not an alarmist. No matter what kind of safety accident using a ladder, it is subjectively caused by paralysis and carelessness. Objectively, it is the cause of the ladder. It is best to choose a ladder with excellent safety performance, high load-bearing performance, durability, lightness and convenience, and at the same time carefully follow the safety guidelines for using ladders, which can avoid almost any accident. It is a responsibility to oneself, but also to the whole family and society. When choosing a ladder, it is necessary to distinguish between safety ladders and ordinary ladders in the strict sense. If you regard the ladder as a simple and primitive tool, then you are very wrong, because then ordinary ladders cannot guarantee Your safety cannot be prevented from sudden and unpredictable hidden dangers and risks.

Aluminum Alloy Herringbone Ladder Is Second Only To Steel In Industrial Usage
Aluminum alloy herringbone ladder is a general term for aluminum-based alloys. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc. Aluminum alloy herringbone ladder has low density, but relatively high strength, close to or surpassing high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the amount of use is only second to steel. Aluminum alloy herringbone ladders are divided into two categories: cast aluminum alloy herringbone ladders, which are used in the as-cast state; deformed aluminum alloy aluminum alloy herringbone ladders, which can withstand pressure processing and have higher mechanical properties than as-cast conditions. It can be processed into aluminum alloys of various shapes and specifications. Mainly used in the manufacture of aviation equipment, daily necessities, doors and windows for construction, etc. Some aluminum alloy herringbone ladders can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance.
