How To Sharpen Tools: The Family Handyman Sharpening your tools Years ago, I drove by a storefront with a hand-painted plywood sign. It read “Tool Sharpening.” Inside I saw a lean old fellow with wisps of gray hair curling from the backside of an old hunting cap. A week later when I walked into the store, he asked me what my name was and started rummaging through a pile of bags and boxes. The next day I gathered my garden tools and brought them down to the same shop. A moment passed, then he looked me in the eye and said, “Why don’t you do it yourself?” That afternoon changed forever how I look at tools. Do It All with Three Simple Tools A Grinding Wheel, a Mill File and a Sharpening Stone You can sharpen most garden tools with a simple 10-in. mill bastard file (Photo 5). A grinding wheel (shown in Photo 4) is good only for removing larger amounts of steel. You can buy all these sharpening tools at home centers and hardware stores.

Flexural Strength for Industrial Coatings - PennCoat Inc. Blog Flexural Strength The next physical characteristic to fall under our gaze is flexural strength, which is simply resistance to bending along the sample’s axial plane — it is different from torsional, or twisting, strength. The standard flexural strength test for plastic materials, including coatings, paints and films, is ASTM D790. A Little Physics With the ends of the sample free to move and pressure applied to the center, the test machine forces a plastic sample to flex, or bend. The formula for flexural strength, σ, under a three-point load is equal to 3FL/2bd2, where: F = force at fracture pointL = support span lengthb = width of sampled = thickness of sample A related physical quantity is flexible modulus, E, the ratio of stress (force) to strain (deformation). Testing Flexural Strength As we’ve mentioned in previous articles in this series, the first step is to mix up the test material and pour it into molds. The sample breaksThe sample deflects 5 percent
Nanotech improves coating technology. - PennCoat Inc. Blog Nanocoatings Coating science for concrete flooring has entered a brave new world thanks to nanotechnology, the use of particles in the 1- to 100–nanometer range — that’s as small as 10-9 of a meter. Particles this small behave according to the rules of quantum mechanics, creating completely new realms of applications. One exciting use of this technology is nanocoatings that can be applied to a variety of surfaces. General Properties The organizing principle of nanotechnology is particle size, so it’s hard to generalize about the wide range of properties these particles have. Water Repellant: Typical waterproofing coatings create an impermeable film that keeps water from getting in or out. The Nanocoatings Industry According to a study performed by Grand View Research, nanocoatings will experience explosive growth, creating a market for 1,262.9 kilotons worth $8.17 billion by 2020.

Preserving Industrial Equipment with Acryllic Urethane - PennCoat Inc. Blog Acrylic Urethane We at PennCoat frequently use an acrylic urethane mastic called Durethane DTM, manufactured by PPG. It can be used to put a hard protective coat on metals, concrete and masonry. The product can produce a high gloss and can be tinted in various hues, with good color retention. It has low amount of volatile organic compounds (VOCs), resists the sun’s ultraviolet rays and is fairly easy to apply. Physiochemical Characteristics Component A of Durethane DTM is the solvent and colorant. Component B is a hardening resin composed of hexamethylene diisocyanate, or HDI (C8H12N2O2), which forms a coating that is resistant to abrasion and UV radiation. Preparation and Application Pre-mix Component A at a moderate speed with a pneumatic air mixer. PPG recommends that you do not apply the product when the temperature of the air, surface or product is below 40°F, with the surface temperature no less than 5°F above the dew point.

Concrete Joints : Installed by PennCoat - PennCoat Inc. Blog Joints Placed in Concrete Slabs For such a thick and heavy surface, concrete always seems to be on the move. As newly poured concrete slabs dry, the loss of moisture causes the material to contract. Certain steps can be taken to help minimize the amount that concrete shrinks as it dries, including: Minimal use of water in relation to the cement content of the concrete and the use of water-reducing agentsUsing clean, coarser aggregatesLow slump and proper consolidationAdequate and continuous curing Most of the time, control joints are introduced after new concrete has dried sufficiently, although they can also be cut with a saw in newly dry concrete — but if you don’t do this promptly, cracks will form. In this article, we’ll look at three types of control relief joints: contraction, expansion and construction. Contraction Joints Contraction joints break up large flat expanses of poured concrete. Expansion Joints Construction Joints
Concrete Densifiers for Polished Concrete - PennCoat Inc. Blog Concrete Densifiers Densifiers are used for polished concrete floors. When added to the concrete, a chemical reaction causes the surface to get extremely hard. While we touched upon densifiers in an earlier blog, we’d like now to examine their characteristics in detail. As is our custom, we’ll zoom in on a product we regularly use at PennCoat, in this case AmeriPolish 3D HS Densifier. Densifiers for Polished Concrete Polishing densifiers penetrate the surface of a concrete structure, such as a floor, to give it a better shine and harden it against wear and damage. New concrete “bleeds” water, which rises to the surface and softens it. Physicochemical Characteristics The key to densifier action is the presence of silicon compounds: Silanes: Polarized compounds with a general formula of SiH4. Proprietary formulations of all three compounds are found in AmeriPolish Densifier, along with surfactants, hydroxides and UV-absorbers such as derivatives of piperidyl sebacate (C21H39NO4). Features
Bamboo: The new super construction material Researchers from the University’s BRE Centre for Innovative Construction Materials, in collaboration with a team from Coventry University and the University of Cambridge, are exploring the use of bamboo for the widespread construction of homes. Bamboo holds a number of benefits over other construction materials – it grows extremely quickly, reaching maturity three times faster than hard woods, and is renowned for a strength that is comparable to steel. However, inherent drawbacks currently prevent the widespread use of this material. Bamboo has limited durability when exposed to UV rays and humidity, and its thin walls and empty internal diaphragm imply that it has poor fire-resistance. The research team is working to develop an understanding of the anatomy and structural applications of Bamboo in order to modify it to overcome these limitations, while maintaining its unique mechanical properties.

SBA_EXPO Japan Pavillion Another goal was to construct the pavilion using methods that were as low-tech as possible, so they argued for simple joints of fabric or metal tape. As the intersection between two paper tubes was pushed up to form the three-dimensional grid, an angle would open and a suitable amount of tension would be applied. Further, since the paper tubes themselves would rotate to draw a gentle S curve, the joint would allow for three-dimensional movement. ハノーバー万国博覧会は、1992年のリオデジャネイロ宣言を受け、環境問題をテーマに掲げている。
