The Basics Of Sandblasting

Sandpaper is used to – well – sand surfaces, meaning portions of the texture of a surface is removed to achieve a desired effect. Sometimes, that desired effect is roughening up a surface to prepare it for the application of paint, primer, and other coatings. Conversely, sometimes what people desire is to have a smoother surface, allowing it to be painted over without any bumps that might ruin the texture, or for surfaces that are meant for humans to touch with their bare skin, making it less likely that one’s skin would be damaged by touching such a surface.
Rather than manually sanding something with sandpaper, sandblasting is often used as an alternative. As a matter of fact, sandblasting is more common than people using sandpaper to achieve such results by hand.

What exactly does sandblasting involve?

Sandblasting, also called media blasting, involves hurling tiny pieces of sand or silica – that’s what’s used in most cases, at lease – towards surfaces that have undesirable textures.

Small pieces of media are used for two reasons: larger objects, like whole sheets of sandpaper, couldn’t be hurled at an objected without causing large, unappealing dents; also, it would be virtually impossible to hurl larger objects, like full-fledged pieces of gravel, at objects.

There will also always be a source of air used to direct and propel such media being used. Typically, the air is taken from an air compressor, or a sturdy metal tank that uses a motor to pull air in from directly outside the machine. When a valve is released to let the air flow outwards, it’s shot out at such a fast rate – due directly to the pressure that’s been compressed in such tanks – allowing the media it contains to actually make a sizable difference in the texture of surfaces it’s sprayed at.

Vacublast Abrasive Blasting systems typically channel air through skinny, strong cords that both maintain the air pressure of their inputs, as well as direct all the air to wherever the media is being blasted.

Also present is a media tank, in which crystallized silica, sand, or whatever other media is being used is contained in.

How do the components involved in sandblasting actually work?

The media tank is connected somewhere in the system, typically directly from the air source. The air from the compressor or blower fans over the media tank, causing a particular amount of media to be blown into the air. Using a device, connected to the media tank with a hose, that’s shaped like a narrow cylinder, users are able to direct the material at whatever surface they want to.

Other facts and basics of sandblasting

Garnet is also used for sandblasting as an abrasive blown at surfaces. It’s also important to keep in mind that sand is extremely detrimental to human health if inhaled – that’s why sand isn’t always used.

Further, because other types of media are bad for human health, you should always use a top-tier respirator or closed air source.

The Art of Making Birthday Cards Stress Free

The giving of birthday cards is a time-honored tradition that is holding strong in the digital age of the 21st century. It is a tradition, however, that can actually create a great deal of unnecessary stress. While giving a card is still an expected social nicety, we still often seem to forget about them until the last minute. This often means expending a great deal of time going to a store, choosing a card and standing in line waiting to pay for it. Not to mention that birthday cards can get rather pricey when purchased individually. Here are 4 tips to help make giving a birthday card a stress-free experience!

1. Stock up

Since the giving of birthday cards is a tradition that is not likely to go away any time soon, you can stock up on a variety of birthday cards so you’ll have one handy no matter the occasion. If you have children, you may want to stock up on several children’s cards, but even if you don’t, you may want to keep a few handy for nieces, nephews and the children of friends. Keep a few somewhat “generic” cards for casual acquaintances or people you don’t personally know well and a few “specialty” cards for close friends and family members. All in all, if you keep an assortment of about 10 cards handy, you should have something to cover every occasion.

2. Buy on sale

One advantage of keeping several Birthday Cards by Charity Greeting Cards on hand is that you can buy them when they are on sale. Greeting card stores regularly clear out their back stock of cards to make way for new ones. When you find them on sale, stock up!

3. Buy in bulk

In addition to buying birthday cards on sale, you can also save money by buying a box of assorted birthday cards, rather than purchasing them individually. By buying a box of cards, you can generally not only save a good bit of money but will also have an assortment to choose from for various types of birthdays.

4. Buy blank cards

If you really want to go all-purpose, you can buy blank greeting cards that can be used for any occasion, not just birthdays. Today, you can even buy cards that come with coordinating stickers that offer greetings like “happy birthday” or “congratulations,” which allow you to customize one card for a variety of different events.
