Five Tips For Buying a Quality Barbecue Grill

2021-02-20T01:26:53.352Z

Does it seem like you have to buy a new grill every season? If you are like most people you might find yourself taking a trip every spring to the discount store to buy another grill. The same barbecue grill that you bought last spring, after a few uses, the legs got wobbly and the grate rusted through. Even a little rust can be bad because it gets on the food and that's never a good thing for many reasons.

They are a few differences that separate quality grills from those one-season wonders. A good quality grill, with proper care, will provide many years of use. Outlined below are five features you should always look for when considering the purchase of a grill that will last you many years.

16 gauge Stainless Steel Grill
The quality of the materials that are used make the biggest difference. Any grill worth its weight will be made of 16 gauge stainless steel. Stainless steel doesn't rust and it's resistant to oxidation caused by heat. Oxidation caused from heat is the leading reason grills rust through quickly. Most discount grill manufacturers will not use low-grade stainless steel as to keep production costs down.

Cast iron grill grates
Cast iron grates will last the lifetime of the grill if proper care is taken. Cast iron grates must be seasoned, just like your grandmother's old cast iron frying pan. Well seasoned iron grates are non-stick and will actually improve with age adding flavor to your food when it cooks. Cheap grill grates are made of steel that is hybrid epoxy polyester powder coating manufacturers with a chrome surface to prevent the steel from rusting. This works well until the first time you use the grill. The reason for this is because the heat degrades the chrome plating causing it to crack. Then the heat rusts the steel underneath causing it to rust from the inside out.

Understanding the Different Types of Coated Steel

2021-02-02T03:26:17.395Z

Main Product Groups

The most common coated steel products are metal coated steels. Their manufacture typically uses cold- rolled steel (although a small percentage is made from hot rolled coil or sheet) which is then coated with zinc or with tin. A further coating is often added to zinc-coated steel in a subsequent process step to produce colour-coated steels.

Zinc Coated Steels

There are several distinct types of zinc coating (or galvanizing). These are

Continuous hot dip galvanizing: in this process, a cold-rolled coil or sheet in immersed in a pot of molten zinc. A common manufacturing technique for hot dip galvanizing steel is the Sendzimir process (which uses a small quantity of aluminium in the china epoxy powder coating). Continuous hot dip galvanizing is presently the most popular method of producing coated steels. Typical applications of these steels include construction (roofs, walls - often as sandwich panels), auto body components (exposed panels), fabrication (metal cabinet frames and walls), agriculture (outhouses, livestock buildings, silos), heating and ventilation (casings, air ducts); and it is very common for the galvanized steel to be further coated (see below) for many of these uses.

Hot dip batch galvanizing - used for small lots in a non-continuous batch process. Typical products can include lighting poles, antenna poles, radio towers, road barriers, power transmission lines, camera poles, motorway crash barriers, pedestrian bridge systems, garden frames, galvanized wire or mesh, street furniture, advertising poles, boilers, ducts, welded tubes and other profiles, etc. The usual production process involves dipping the shaped steel fabrication into a molten bath, which can be up to 12 metres in length.

Electrolytic galvanizing - a somewhat popular coating technique producing a zinc coated steel with a coating of 25-100 g/m2 per side - although capital costs, operating costs and market preferences have swung demand away from electro galvanizing towards continuous hot dip galvanizing in recent years.

Huacai Protective Coatings

2021-01-26T02:08:36.031Z

Coatings for use at high temperatures on a superalloy substrate can be defined as a surface layer of material, either ceramic or metallic or combinations thereof, that is capable of precluding or inhibiting direct interaction between the substrate and a potentially damaging environment. This damage can either be metal recession due to oxidation or corrosion, or a reduction in substrate mechanical properties due to the diffusion of harmful species into the alloy at high temperature. Aerospace coatings used on superalloys do not function as inert barriers. Rather, they provide protection by interacting with oxygen in the environment to form dense, tightly adherent oxide scales that inhibit the diffusion of damaging species such as oxygen, nitrogen, and sulfur into the substrate. Coatings must therefore be rich in those elements (such as Al, Cr, or Si) that readily participate in the formation of these protective scales. Essentially, they are reservoirs of those elements; the supply is continually being used to reform new scale to replace that which spalls as a result of thermal cycling or mechanical damage. Thus, by the nature of its protective mechanism, the usable life of a huacai powder coating is governed by its ability to form the desired protective scale and to retain or replace that scale as needed.

By far the largest use of coatings on superalloys is on components in the hotgas section of turbine engines, hot section components, that is, combustors, blades, and vanes. The need for such coatings surfaced in the aircraft engine business in the 1950s when it became apparent that substrate compositional requirements for improved high-temperature strength and optimum high-temperature environmental protection were not compatible. Increasing operating temperatures caused excessive oxidation of the high-strength nickel- and cobalt-base superalloys being used for turbine blades and vanes. This led to the development of the simple aluminide diffusion coatings that solved the oxidation problem. Several of these aluminide coatings are still in use today.

Critical Considerations For Labels In Harsh Environments

2021-01-15T01:51:32.705Z

While product labels are often the least expensive design components and the last items considered when introducing a new product, product labels have a significant impact on a product's market appeal and merchandising. Also, the product label can cause major headaches and unnecessary costs for the OEM manufacturer - if the label design and construction are not properly matched to the customer's application requirements.

Consider the following examples: An elevator manufacturer changed from enamel paint to a powder coated paint after the product has been on the market for several months. Subsequently, their end customers experienced an adhesion failure of its labels not knowing that epoxy powder coating coated paints can be a bonding challenge. The company had to shut down their process and implement expensive field rework. Unfortunately, the label manufacturer was not consulted when the company switched to its powder coating process. In the end, a new label construction with a more aggressive adhesive solved the problem.

A shipping company utilizes labels adhered to their trailers for critical tracking of inventory in transit. The labels were applied at a freezing temperature, which never gave the pressure sensitive adhesive label a chance to "wet-out" and properly bond on the substrate. Consequently, labels fell off in-transit, creating delays and additional shipping costs.

For many product manufacturers, their labels may not be recognized as a critical component. However, most companies expect their labels to last for the life of their product to ensure that the critical information on the label is available to their customers

Durable Labels

Durable Performance Labels or Harsh Environment Labels from 3M withstand a wide range of environmental conditions over the product life. According to Peter Garin, manager at 3M Graphic Market Center, if a missing or damaged product label can cause "potential harm to the consumer, the environment or the manufacturer," then Durable Labels using 3M face stock and adhesives should be considered for that product.

Epoxy Filler - History, Tips and Advantages

2021-01-08T01:14:33.664Z

Epoxy Filler
Epoxy filler is a general term used to describe filler used to fill in cracks, dents and surface imperfections on metal and non- metal surface. This product should be strong, durable, weather and heat resistant. It should apply easily and come in a single component instead of mixing a resin and hardener or catalyst. There are many uses for this type of filler and in many industries as well.

They needed metal filler that was one part or single component, easy to apply, dries fast and looks like the metallic look of the casting. Metal fabricators, welders, auto body shops, ornamental metal workers, hobbyists and do it yourselfers were soon introduced to this unique and ready-to-use metal repair and patching compound.

Liquid Painting/Coating
In the past, these metal parts were liquid coated with a latex, alkyd, solvent based or industrial liquid paint and coating to protect metal surfaces against rust, corrosion, chemical attack, weathering or immersion. Liquid coating was the only way to paint and protect these surfaces and the paint was usually solvent based applied through an airless or hvlp paint system. When there was a need to apply a filler to repair these dents, voids, rough welds and surface imperfections, two part epoxies made with a resin and a hardener with pigments, metal or plastic fillers could be used to mask and hide these voids and simply liquid painted over.

New Type of Coating
While liquid painting was common, regulations forced paint manufacturers to re formulate paint and coatings to contain less solvent which would also lead to the development or powder coating. This is a type of coating which is applied as a dry powder. The powder does not need solvent to keep the filler and binder parts in a liquid form. This type of paint is applied with an electrostatic gun and is then baked/cured under heat usually in an industrial oven which helps it flow and form a skin. This new development is mainly used for coating of metals, appliances, extrusions made from aluminum, auto and bike parts.

Graphite Low Friction Coatings For Conveyors - Lose the Grease!

2020-12-28T01:17:11.900Z

Graphite low friction coatings, like oil-grease lubricants, are excellent choices for preventing wear of conveyor drives, sprockets, take-ups, and related moving parts. Without them, metal surfaces rub and are quickly stripped of their oxides. The result is strong atomic attraction between the metals.

What does this mean? Well, consider increased friction, more wear, and, under higher PV (pressure-velocity) combinations, galling or seizing.

So when is graphite lubricant preferable to oil or grease? That's easy.

Just take a look at indexing equipment using gas compressors or air pumps. Oil and grease lubricants can quickly lose their viscosity, even volatilize and contaminate the environment. Consider service temperatures dipping to cryogenic levels, or exceeding a few hundred degrees Fahrenheit, and you will see what I mean.

Wear, too, with oil-grease lubricants, can sometimes accelerate, based on their "attraction" of abrasive dust. So much so that they can become grinding compounds!

That is what makes compounds like dry graphite ideal. High temperature conveyors using carbon graphite, for example, can benefit on several factors: higher load, faster speed, reduced wear on the counter-face, motor downsizing, and, of course, lower friction. Coefficient values, though system-dependent, can be as low as 0.02 to 0.04.

Today, graphite can be purchased in a variety of forms, from powder coating graphite to colloidal dispersion. So, talk to a coatings applications engineer, before your next conveyor design and build, to see how your specific requirements can be met. Dimensional adds are often negligible. And the dry film lubricant will only enhance the properties of your surface hardened steel.

Graphite properties have provided answers to the harshest of conditions for years. And they will continue for years to come, as new applications for graphite low friction coatings emerge.

Powder Fire Extinguishers and the Appropriate Use

2020-12-21T02:26:58.313Z

Powder fire extinguishers are really quite common. These are the fire extinguishers that can be readily found in homes, garages, and sheds, are relatively inexpensive to purchase, and have a host of uses that can save property and lives. A powder fire extinguisher is not appropriate for all types of fires. There are specific fires that respond well to a powder fire extinguisher and types of fires that simply don't. A powder that is one of four different chemical bases is packed into a highly pressurized canister and charged to expel at a high rate of psi.

The most common powder that is packed into these canisters is baking soda and starch. The baking soda and starch mixture that is stored inside the canister of a powder fire extinguisher is usually dyed in order for the user to see the areas which he or she has hit and those which have been missed. It also makes it more readily seen when it is time for clean up.

Baking soda and starch electrostatic powder coating paint fire extinguishers are best used on organically based fires. This means that they are appropriate for fires that are started from wood, paper, or dried plants. This type of powder fire extinguisher releases carbon dioxide to counteract the effects of oxygen on the flames.

Potassium bicarbonate is a powder fire extinguisher that is twice as effective on petrol fires than baking soda extinguishers. These are the fire extinguishers that can be found on airplanes. This is because it is the only packed canister that contains a compound that does not react to alcohol. These powder fire extinguishers are suitable for organic fires and those caused by flammable liquids.

Ammonium phosphate is the third type of packed compound in dry powder fire extinguishers. These are recommended for use on organic fires, flammable liquid fires, and fires that are based on flammable gases. The powder used in these extinguishers is expelled in the same form that they are stored. However, when the powder reaches a medium to high temperature, it melts and spreads itself over the base of the fire and deprives the flames of oxygen.

Curing Powder Film

2020-12-15T02:47:46.491Z

After the powder has been applied to the component it is heated. When heated, the powder film will first melt, flow and bond to the substrate being coated. Continued heating will "cure" the powder - curing involves a chemical reaction called "cross linking" and the resultant "cured" coating will not, like the original powder, melt or dissolve in solvents - it forms the protective coating we seek.

Most powders cure at around 180C and must be at this temperature for around 10 to 12 minutes and this time does not include the heating up or cooling down of the component but is the dwell time: the length of time that the component must be held at the appropriate temperature for curing to take place.

The dwell time and oven temperature will vary according to the size of component, atmospheric conditions and the manufacturer's recommendations for that particular product.

The most frequently used methods of heating aluminum profile powder coatings are convection and radiation, both involve the component being passed into or through the heated area of an oven in order to melt and cure the powder film. The ovens will usually have an extractor to purge the chamber of the small amount of waste gases produced during the curing process.

Convection curing

This type of curing is by far the most popular method used in the curing of powder coatings. The component will be thoroughly heated to the required temperature where curing will take place. This type of oven usually consists of a large insulated box into which the parts will be placed for curing, or a tunnel through which the parts travel, via heat seals, into the main chamber of the oven.
