Green silicon carbide 180

Types of green silicon carbide 180

Silicon carbide abrasives are produced in different grades based on individual needs. Silicon carbide is a hard material and is used to make many products. It is even harder and denser than aluminum oxide, meaning it stays sharp longer in a tough environment.

• Coarse-grade

  Green silicon carbide 180 coarse-grit silicon carbide blasting media is used for heavy-duty surface preparation. It is beneficial in the cleaning of very rough metal surfaces and removing heavy oxides, rust, and scale deposits. It is also used in profiling softer materials, such as aluminum and brass, to prepare them for further machining or coating laying.

• Medium-grade

  Green silicon carbide 180 medium-grade silicon carbide blasting media offer a balance between material removal and surface finish. They gently clean metal surfaces and remove moderate oxidation and contaminants. They are also used to texture softer metals, such as aluminum, for aesthetic finishes or improving adhesion before coating.

• Fine grade

  Fine grade silicon carbide blasting media is suitable for light surface preparation and polishing. It does not heavily etch the surface it is used on; it is good for cleaning delicate metals like gold and silver. Advanced technology polishing applications benefit from fine-grain silicon carbide as it provides a smooth finish required for high-end products.

• Extra fine grade

  Extra-fine green silicon carbide is used to produce high-gloss finishes on a variety of surfaces. In metal finishing, it is used for ultra-fine polishing of exotic metals such as titanium and platinum. In glass and ceramics, it is used to ensure an ultra-smooth surface that provides no etching, which may lead to cracks or other damages.

Function, feature and design of green silicon carbide 180

Function

This is a versatile abrasive widely applied in many industries because of its unique properties. Its primary function is as an abrasive used in grinding and polishing processes to achieve smooth, fine surfaces on various materials. In ballistic protection, it is used to make bulletproof vests and many other items. Its hardness allows it to maintain a sharp cutting edge even after prolonged use, making it invaluable in applications that require constant wear resistance.

Features

• Hardness: Green silicon carbide is almost as hard as diamond; it holds its own against aluminum oxide, which is still the hardest. This hardness is essential in ensuring that abrasives cut effectively and do not degrade quickly during usage.
• Sharpness: It has sharp, angular particles that fracture easily during use. This sharpness allows for aggressive cutting, grinding, and polishing action. The sharper the abrasive grain, the deeper the material removal in a shorter time.
• Grit size: The grit size of the abrasive particle affects the surface finish. Green silicon carbide 180 grit produces a relatively coarse surface compared to finer grits, making it ideal for tasks that require quick material removal but still leave a smooth enough finish for many applications.
• Chemical resistance: It has high chemical resistance, meaning it does not easily react with acids, or any other chemicals, leading to a longer service life than other abrasives in critical environments.
• Thermal properties: Green silicon carbide has a high thermal conductivity of 120 W/mK, which helps it dissipate heat during grinding or cutting operations. This feature prevents overheating of both the abrasive and the work material, which is important in maintaining the integrity of the surface being worked on.

Design

In ballistic armor, the design consists of many uniform-sized granules with a well-controlled degree of purity. Such a design ensures improved mechanical interlocking for better energy absorption when the projectile hits the vest. In grinding wheels, the unique abrasive grain shape and the type of bond used in holding it together is another reason for its effectiveness. The design also ensures minimal clogging; thus, the product continuously exposes sharp edges that enhance cutting performance throughout its usage.

How to choose green silicon carbide 180

When choosing green silicon carbide 180 grit, there are several factors that need to be considered depending on the product's end use.

• Material hardness

  When purchasing green silicon carbide 180 grit, the hardness of the material to be machined has to be considered. The silicon carbide abrasive is suitable for softer metals like aluminum, brass, and copper. For harder materials like steel, carbide, or glass, the silicon carbide grit can be used because of its superior hardness and sharpness.

• Application type

  Green silicon carbide grit is used in various applications, including blasting, grinding, and lapping. Grit 180 is only suitable for polishing and blasting applications because of its coarse texture. Finer grits should be applied for grinding and lapping. This is because they offer a smoother finish and better control over machined surfaces.

• Grain shape

  Choosing the grain shape of the silicon carbide material depends on the application. For example, angular grains are favorable for metal surface treatments because they provide a better finish. Spherical grains are more suitable for drilling and blasting because they demand a less aggressive cut and more of a soft finish.

• Purity

  When purchasing green silicon carbide 180 grit for industrial use, consider the purity of the material. The more the material is purified, the better the quality. For industries that require small defects, like semiconductor or optical equipment manufacturing, only high-purity silicon carbide should be used.

• Delivery time

  Consider sourcing only from suppliers that can deliver quality products within a short time. Ensure that the supplier has sufficient stock to supply the required amount promptly. Also, confirm that the supplier has no history of delays in past deliveries. Therefore, a business must liaise with several suppliers to have sufficient stock demands.

• Supplier reliability

  To ensure a consistent supply of quality products, a business must work with a trusted and reliable supplier. Before making the first purchase, the buyer has to vet the supplier and the quality of the products they offer. Ensure the supplier has sufficient stock to supply the required amount.

Maintenance and repair of green silicon carbide 180

To ensure the green silicon carbide 180 grit product has a long life, the following maintenance needs to be observed. This not only applies to the silicon carbide grit but also to other industrial products in general.

• Preventive maintenance

  Preventive maintenance involves doing regular and routine maintenance so that the product doesn't fail unexpectedly. Preventing maintenance can be conducted by knowing the common failure modes of the silicon carbide abrasive. In some materials, they may wear out, become contaminated, or change from one texture to another. By knowing this, then maintenance can be done to counter these failure modes before they occur.

• Corrective maintenance

  After knowing what common maintenance problems follow the silicon carbide material, corrective maintenance is simply correcting these problems. All that is left is to apply the knowledge to fix the abrasives. This may involve changing worn-out equipment, fixing contaminated workstations, or scheduling more intensive maintenance to fix structural problems with silicon carbide materials.

• Condition-based maintenance

  In condition-based maintenance, maintenance is performed only when needed. This is done by taking several measurements that give an indication of the actual state of the equipment. These measurements can tell when the silicon carbide material is worn out or when the grit is losing its edge. This, in turn, helps avoid maintenance that is not necessary and increase the life of the material.

• Time-based maintenance

  This is the basic form of maintenance where the time intervals at which abrasive grit should be changed or maintained are predetermined. Such maintenance is done often because, after a certain period of time has elapsed, it is scheduled to do maintenance regardless of whether the material needs it or not.

• Dos and don'ts

  Another way of maintaining the silicon carbide industrial product is through the dos and don'ts approach. This can be combined with condition-based maintenance. After doing condition-based maintenance, the maintenance team should enumerate what to do and what not to do based on the current condition of the material.
