Industrial Metal Adhesives

Friday, November 5th, 2010

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.

Types of Abrasives – Basic Information Guide

Monday, August 16th, 2010

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.
