Types of Industrial Abrasives and How They Are Used

admin — Fri, 10 Jun 2011 07:08:23 +0000

When it comes to abrasives most of us will think of sandpaper, yet there are plenty of others types that are being used the world over today. Along with sheets of abrasives there are blocks and even wheels made of these. It is the wheel types which are most commonly used by various industries and these will be constructed of various materials, namely resinoid, rubber or vitrified. In this article we take a look at two types of industrial abrasives and how they are used.

1. Vitrified Industrial Abrasive Wheel

As you will soon learn this particular type of wheel is being used by a number of different industries. The material is one that works effectively on both glass and wood and also has the strength to be able to work on high alloyed steel.

There are numerous benefits to be gained from using these kinds of industrial abrasives over the others available, especially for an industry where hard materials are being worked on.

So just what are the main benefits to be had from using this form of abrasive.

a. Little or no liquid is needed to keep the material being worked on protected. So not only will this keep costs down for the company but also helps to protect the environment.

b. Even when being cold cut this abrasive is one that will cause no damage including burns to the surface of the material.

c. This is an abrasive that can be used at high speeds and so helps to increase a business’s productivity levels,

2. Resinoid Industrial Abrasive Wheel

This kind of abrasive wheel is like the vitrified types used in many different industries today. But there is one difference between this and the vitrified; being that this one is far less brittle. Because of this property it is used for much heavier duty applications like the grinding of rail tracks or cutting metals to create vehicles in the automotive industry.

Like the other industrial abrasives we discuss in this article this one comes with its own benefits and these are as follows:

a. Unlike other forms of industrial abrasives this one removes a lot more material a lot more quickly.

b. It is very resilient to side loads and so can be used in a lot of different ways for many different kinds of applications.

It is amazing just how many different types of industrial abrasives are used throughout the world today and how important they are to various industries.

However, not only do they help to ensure that levels of productivity remain high within a particular industry, especially when we look at the current economic situation. But there are some that are kind to the environment as well.

Wireline Pressure Control Equipment

Ralph Serpe — Sat, 14 May 2011 07:01:47 +0000

Wireline pressure control equipment can be available in two basic flavours: they can be part of a standardised range of wireline pressure control equipment products, or they can be specially designed and made to fit in exactly with a customer’s requirements. It is necessary for wireline pressure control equipment to be designed and produced so that it is able to withstand excessive pressures and resist excessive corrosion within the well. Pressures may be as high as 15,000 pounds per square inch, or even higher. Temperatures can also fluctuate and can be found in extreme ranges. Wireline pressure control equipment must be manufactured to withstand everything that is thrown at it. In any wireline operation it is necessary to maintain the pressure in the oil well. This is achieved by use of a stuffing box, or packing gland. The stuffing box essentially allows the wireline to move freely up and down within the well, confining the fluids and gases within the wellbore and without losing the pressure inside.

As a primary element of this equipment, the stuffing box has several important tasks to perform. It has to maintain well pressure while allowing braided wire to move freely through it. As the braided wire is not uniform in diameter, this presents a problem that requires special attention. Packing elements made of rubber form a seal around the wire in the first instance. A wireline valve forming a second barrier seal is also required. If a risk of failure of the stuffing box happens or is suspected, this can be closed around the wire to prevent excessive pressure loss. The wireline valve also requires a grease injection head positioned above it, especially in the case of braided wire, to guarantee a proper and acceptable seal.

A wireline blowout preventer can produce a tight seal around slick line or braided cable. It is positioned between the lubricating assembly and the wellhead. Two opposing horizontal ram assemblies are commonly used to compress an effective tight seal around the wireline. This part of the equipment has the effect of containing and controlling the well pressure. Apart from the wireline pressure control equipment, the pressure inside an oil or gas well is controlled by drilling fluid pressure. Both components work together to provide satisfactory and safe overall pressure control. The well hole must have enough drilling fluid pressure to overcome the formation pressure, the pressure exerted inside the well by oil, gas and water, for the drilling operation to proceed with safety.

Abrasives Hair Removal Techniques

Linda Greens — Sat, 26 Mar 2011 06:18:54 +0000

Abrasive is the most different hair removal method among all the available hair removal methods. With is hair removal method Pumice Stones are used to remove the unwanted hairs from the body. Actually Abrasives are also used to smooth or roughen the surfaces by rubbing. Some common abrasives are – pumice stone, powdered glass, abrasive hand gloves pumice dust, sandpaper, aluminum oxide. Fine-grained graphite papers are used in metal and woodworking. Pumice stones made from powdered pumice rock are then pressed into solid “stone” shapes. These are available in shops, and their rough texture is ideal for removing dead skin from the feet.

At the time of using abrasive for hair removal, the skin should soapy and wet. Abrasive removes the unwanted hairs from the body very slowly. Because of this reason, Abrasive is not advisable for removing hairs in large amount. Abrasive is done by rubbing the abrasive material like pumice stone/dust, sandpaper etc. on the skin in a circular motion. Actually sandpaper is gentler than the other materials. Abrasives can be the right method for removing the unwanted fine hairs from the body. For fine hairs, an abrasive like pumice stone should be used. The fine hairs can be removed easily without causing any damage to the skin. Abrasive does cause redness but it disappears after sometime. The result of abrasives last for three weeks.

Adhesives in Everyday Life

Linda Greens — Mon, 14 Feb 2011 09:18:26 +0000

Small things often play important roles in our lives and often it goes un-noticed and un-acknowledged. Adhesives are just one such category of products which have immense usefulness but are hardly acknowledged. So let us review some of real life activities where role of Adhesives is embedded but we never get to know the heroes behind the curtain. All of us visit local grocery shops and get our routine Food stuff. A Bottle of Beer, ready to eat frozen meals, instant foods they would not be the same as we are used to knowing them without Adhesives. The Label on the Beer bottle – How does it manages to be there on a damp bottle and never come off, however when the same bottle is given for recycling the label must be able to get detached without much of the fuss. So what creates this magic on a bottle label, its adhesives…

Right form our childhood we are use to fix medicated tapes on our cuts and bruises. What makes the tapes stick to our body without causing any harm and help heal our wounds fast enough, its adhesive. Medical Industry also has numerous high end uses where adhesives are of critical importance. The Beautiful piece of art work in our drawing room which gets admiration of all, but behind the scene adhesive which has held it there for ages never ever gets notice of anyone. Our personal Mobile phone, I-pods, Lap top computers, Shoes, Clothing’ Houses we stay in, Motor vehicles we travel in, Aircraft, Sea Vessels, Space Missions, you name and you will find indispensable utility of adhesives in all of the above. But still it remain un-notices. Above are just a few instances and importance of adhesives which are taken from our everyday Life. Lets hope it have tickled your brain cells to be more inquisitive to find out and know more about adhesives hidden behind the scenes.

Knowledge of Chemistry of Explosives

Linda Greens — Mon, 20 Dec 2010 03:46:49 +0000

Both Glucose and Explosives liberate energy but rate of liberation is slower with glucose but instantaneous with explosives. Another differentiation is that the glucose contains C carbon, H hydrogen and O oxygen atoms in molecule but the explosive necessarily contains N nitrogen atoms. The C6H122O6 is a glucose molecule but CH2ONO2CHONO2CH2ONO2 is Nitroglycerine (NG) which explodes to form a mixture of steam, nitrogen CO2, and O2 at 30000C. So a rate of Chemical Transformation from one form to another Chemical Structure is significant to define a role of a chemical.

The NG is also known as Dynamite, discovered by Alfred Nobel, Swedish engineer, in year 1867. The fortune acquired by manufacture of NG led Nobel to establish a world famous Nobel prize. When Ammonium Nitrate as an Oxidant is added to the NG, then it is called as Ammonia Dynamite but on addition of Sodium Nitrate, it is named as Straight Dynamite. Perhaps keeping a current situation in the mind, it is essential to be in possession of fundamental knowledge of chemical explosives. It is in interest of the Safety, and Welfare of the society. There are 2 categories of Explosives based on their Detonating nature. The first is low Detonating and the second is high detonating with low (rate of detonation, 900 ft/sec) and high (4 miles/second) rate of chemical transformation respectively.

Detonating explosives are further divided into Primary and Secondary explosives. Typical primary explosives are Lead Azide [Pb(N3)2] and Mercury Fulminate [Hg(CNO)2] but secondary needs a Booster to bring them to detonating level. Secondary explosives are Tetry, PETN and Cyclonite. Chemically the explosives belong to category of Internal Oxidation-Reduction [IOR] compounds with a Pyrotechnically Active Group of atoms within the molecular structure. Technically group of atoms are named as Explosophore, the Azides, Bromates, Chlorates, Chlorites, Iodates, Nitrate, Nitrites, Perchlorates and Picrates. Other examples of IOR are NG, Picric Acid, Ethylene Glycol Dinitrite, as these contain several Nitro Groups. Fundamentally Artillery Ammunition contains- Primer (KCLO3, Potassium Chlorate), Igniter (Black Powder), Propellants (Smokeless Powder), Bursting Charge, Booster and Detonator.

Industrial Metal Adhesives

Acrylic adhesives are known for their excellent environmental resistance, which means they can stand up to a pounding in extreme weather conditions, such as rain, sleet, or frost. Also, compared to other resin-adhesives, acrylic adhesives have a fast setting time for jobs that need to be finished quickly. Cyanoacrylates, more commonly known as super glue, is a type of acrylic adhesive that cures instantly on contact through a process that involves surface moisture. If bonding metals together that will be placed in high temperatures, the types of adhesives that would work best for the job are Phenolic, melamine, and urea formaldehyde resins. These are thermosetting bonds that are strong and will hold up for long periods of time when exposed to intense heat. This is a popular adhesive for bonding industrial parts, since they are often exposed to these high heat levels.

Polyurethane adhesives offer a strong bond, but it’s one that includes a great deal of flexibility. These types of industrial metal adhesives also perform well on durability tests and have a high level of impact resistance. Rubber and silicone adhesives are also offered as sealants. The rubber examples of these offer the most flexibility when needed. The silicone-based adhesives and sealants, on the other hand, are more rigid and offer a high degree of durability, in addition to resistance to high temperatures.

The previously mentioned adhesives are all defined on their chemical makeup. There are others, however, that are defined by their adhesion properties. These include hot metal adhesives, pressure sensitive and contact adhesives, thermoset adhesives, and UV curing adhesives. Hot metal adhesives can be softened by exposing them to heat and hardened again by cooling off. This allows for repositioning of metal parts in case a mistake is made, or if finite measurements need to be in place. Thermoset adhesives are set into place and cured using heat or a mixture of head and pressure. Finally, UV curing adhesives use ultraviolet or other types of radiation to cure, offering a permanent bond that doesn’t need heat to set. There are plenty of industrial metal adhesives to choose from. You simply need to decide what the job is and what special requirements the bonds need to have. Whether they need flexibility, extreme tolerance to heat, or if they need to stand up to harsh weather, there is an adhesive out there that works well with just about any condition.

Bearing and Plain Journal Bearing

Linda Greens — Tue, 28 Sep 2010 08:47:31 +0000

In the modern world, there are two types of bearings. They are the plain (sliding) and rolling element bearings. Bearings are machine elements that permit directed relative motion between two parts. Forces are transmitted from one part to another without allowing motion in direction of the applied load. A journal bearing consists of an approximately cylindrical body around a rotating shaft. This journal bearing is used either for supporting a radial load, or simply as a guide for smooth transmission of torque. Most common applications of bearings are the plain circular bearings type. Lubrication usage, on the other hand, range from a simple inlet hole to axial, circumferential, and helical grooves for efficient lubrication distribution.

The plain bearing applications include reciprocating sliders, rotating or oscillating cylindrical members sliding in annular sleeves, and rotating or rotationally oscillating disks sliding on mating disks. The advantages of plain bearings are as follows: lower first cost, simple design, small radial space required, quiet operation, not so sensitive to dust or grit, less likely to be subjected to fatigue failure, easy to replace,. Material types for the plain bearing should have the following: adequate compressive strength, good fatigue strength, low elastic modulus, good ductility and low hardness, high thermal conductivity and compatible thermal expansion coefficients. The shaft must be made from low or medium steel or steel alloys. For the bearing element, bronze bearing metal, ‘babbit’ or ‘non’ metallic materials are used.

Types of Abrasives – Basic Information Guide

Linda Greens — Mon, 16 Aug 2010 09:05:10 +0000

Abrasive is a very hard material, commonly used for grinding, polishing, sharpening, cutting, buffing, drilling, and honing the surfaces, they can be differentiated into synthetic or natural. Many a synthetic abrasive is productively equivalent to an organic mineral. It differs only in the fact that synthetic minerals are manufactured instead of mined. If natural minerals are impure, they tend to be less valuable. Nowadays, they are synthetic. Some of the abrasive minerals (zirconia alumina) appear naturally though sufficiently more intricate and expensive to acquire , because of this, synthetic stones are made use of industrially. These are also called artificial abrasives. Other forms of artificial abrasives comprise ceramics, silicon carbide (carborundum), zirconia alumina, alumina or aluminum oxide.

Abrasives structured for individual purposes. Most of the organic abrasives are minerals, Generally synthetic and natural come in a gamut of shapes, commonly known as coated or bonded abrasives, including wheels, belts blocks, discs, rods, sheets & loose grains. Manufactured abrasives are classified into two types coated, and bonded abrasives. Bonded is one of the abrasive materials that are hold within matrix, and aluminum oxide. Abrasives contain sintered material. This type of matrix is known as a binder also called as clay, rubber or resin. This combination of binder & the abrasives are normally structured as wheels, sticks, blocks. These are commonly used as aluminum oxide, silicon carbide, garnet, tungsten carbide.

Bonded abrasives are required to be dressed after they are used. Dressing includes various processed including cleaning the waste material from the surface and revealing the new grit. It depends upon the abrasive and how it is used. Coated abrasives are also minerals that are used in the same way as bonded abrasives. Sandpaper is a best example of coated abrasive. Coated abrasives are structured for use in orbital sanders. To know more about Abrasives, please read our useful section on the types of abrasives in detail.
