We all know that resistance training can be the key to a great workout regimen, and one of the best ways to reach your strength training goals is by using  weight plates . No matter what level of strength training you do, barbells and weights are going to be your most valuable tools for an effective workout. Barbells are only as effective as the weight plates that are attached to them, so the type and weight of your plates can determine how far you progress in your training. In this guide, we’ll talk about how weight plates can impact and benefit your workout, as well as how to choose the best weight plates for your  Fitness Equipment . WHAT IS A WEIGHT PLATE? In case you’re a newbie to the gym, weight plates are the heavy, plate-shaped discs that are attached to the ends of barbells. In strength training, weight plates enable you to achieve your desired lifting weight in a wide range of resistance training and muscle isolation exercises. And, as you’ll find out below, yo...

Silicon TIR lenses  also known as total internal reflection lenses, which are used to collect and process light using the principle of total reflection. Use Tracepro software to trace the light passing through the silicon TIR collimator, resulting in a light energy utilisation of 95.26% and a beam divergence angle of 15° or less. Optical silicone TIR lens has the function of total reflection technology+medium, every light ray of silicon TIR optics can be controlled and used, generally there is no secondary spot, and with a good looking light pattern.  Silicon TIR bubble lens can improve the utilization rate of LED light energy. It's designed to use penetrating focusing in the front, and the conical surface can collect and reflect all side lights. The overlap of these two kinds of lights can achieve perfect light utilization and beautiful spot effect. TIR reflector can be made of PC, PMMA or silicone, for this silicon TIR reflector we produces, it is made of optical liquid...

    With the rapid development of modern construction projects, the depth of foundation pits is gradually increasing and the rock layer is becoming more and more complicated, so the support becomes an essential part to ensure the safety of foundation pit projects. Many projects near the sea or near the water will encounter drifting sand layer, which has the characteristic of high fluidity and brings considerable difficulties to the support of various projects. 　　 I. Difficulties in the construction of anchor rods in fluvial sand layer 1. Containing groundwater The sand grain size of the flowing sand layer is relatively uniform and the porosity is large, which is a kind of sandy soil layer in fluid state. It is characterized by loose structure, poor shear strength and high groundwater level. It generally appears in areas with more rivers and rich groundwater. In the foundation project, the flowing sand layer needs to pay attention to blocking sand to conduct water, and if ...

Guardrails   have become a common sight alongside highways and mountain passes, but few people may have considered the importance of installing them. In this article, we will take a closer look at the reasons for installing   traffic barrier .     Prevent Crossing from One Highway to Another When placed in a central grassy area between two relatively flowing highways, the guardrail is called a central guardrail. Unlike those found on the side of the road where only beams are attached to one side of a wooden or steel post, these posts have steel beams on both sides. This is to prevent impacts from both sides.   Preventing Vehicle Collisions with Dangerous Objects The risk of collision with inexcusable objects is high when the motorist loses control of the vehicle and the vehicle veers off the safe road. If the vehicle collides with an object such as a tree, wall, culvert entrance or pole, the full impact of the collision will be borne by the vehicle and its occup...

    When looking at   rubber conveyor belts , on the surface they all appear very similar. However, when designed and manufactured correctly, each different specification of rubber conveyor belting can have special properties to suit particular applications. The following different rubber grades follow the ISO 433 standard.   Grade A - Abrasion Resistant   Abrasion-resistant rubber, also known as Grade A, is used when the conveyed material is very rough and abrasive, and causes the rubber to wear from the belt too quickly. The conveyor's specific cleaning system, such as brushes, scrapers and/or conveyor skirting, can also contribute to conveyor belt wear.   Grade A rubber is used when the wear of the conveyor belt would occur too quickly when using general purpose grades. Even though Grade A rubber is more costly than general purpose grades, the cost of removing and installing replacement belts frequently can be excessive. Therefore, it may be more cost ef...

    PET bottles have long penetrated into every part of people's lives - whether it is food, beverages, or cosmetics, or even the medicines we use, you can see it in them. But how are these PET bottles with different shapes and functions produced? The answer lies in the fully automatic production of PET blow molding machines. This article gives a detailed description of the production principle, application scenarios and production advantages of the PET bottle blowing machine, so as to help you get a preliminary understanding of the PET bottle blowing machine and gain some inspiration. What is a PET blow molding machine? The definition of a  PET blow molding machine   is a production machine used to make bottles of different shapes and sizes. How it works is not complicated: relying on the applied air pressure, the blower blows air into the heated preform and sets it with a specific mold that wraps it. In detail, the overall production process of the blow molding mac...

Acetaminophen (otherwise known by brand names such as Tylenol) is one of the most widely used pain relievers. Almost 60 years of widespread use have made acetaminophen a household product. It ’ s distributed over the counter (OTC) in most countries and judged safe by the scientific community. However, acetaminophen is also one of the most common medications involved in overdoses (the medical term for taking more of a medicine than you should) and is the most common cause of drug-induced liver failure. Surprisingly, we are only now coming to understand how  acetaminophen   works — and recent research shows that we may need to develop a better understanding of the need for caution when using acetaminophen, especially when it comes to avoiding some of the risks associated with its use. Past research suggests these can range from increased asthma to interactions with other medications or the risk for developing other health concerns (such as kidney toxicity, bone fractures, or blo...

 Logistics is a very progressive industry that links consumers and producers through a supply chain network that employs various modes of transportation, most notably trucks. A semi-truck without an attached trailer at a given time is known as a " Bobtail truck " or said to be "Bobtailing.” It’s difficult to imagine trucking without Bobtailing. A Bobtail truck does not contain any freight, so it cannot generate revenue for its owner. This is one of the reasons that "Bobtailing" is often confused with "deadheading.” Both terms refer to cargo-free trucks at a specific time, but a small difference exists. Bobtailing is driving a freight carrying truck without an attached trailer, whereas in "deadheading,” trucks have an attached but empty trailer. In this article, we will discuss everything you need to know about Bobtailing. What are the different types of Bobtailing? What does the term mean? And why do truck drivers dislike Bobtailing? Where Does The Te...
