Missing a lint roller altogether? No matter what your lint-roller situation, we¡¯ve got you covered. And the good news is, all this project takes is two ingredients you probably have at home: a paint roller and some (ideally good quality) duct tape. The process of making your very own, super-powered lint roller is simple ¡ª just wrap the tape, sticky side out, around any paint roller, and then get to work on your clothes, couch, or virtually any other fabric you can dream up. Masking tape, painter¡¯s tape, or basically anything you have on hand will work, too. On a big or small roller. You¡¯ll want to make sure to spot test first, especially if you¡¯re using it on something nice, since sometimes cheap duct tape can leave gummy residue on fabric. 3 Reasons to Use Your Super-Powered Lint Roller 1. When you don¡¯t have a lint roller at all The super-powered lint roller is a perfect option if in a pinch if you can¡¯t seem to find your existing lint roller or you don¡¯t have one. 2. Cleaning up a big, hairy mess If you¡¯re a pet owner (or live with a human who sheds), you know what it¡¯s like to discover big, hairy messes in unexpected places. (Gross.) These heavy-duty or everyday hair-ridden scenarios are where your super-powered roller will come in extra handy. It¡¯ll do a better job of picking up lots of hair, without having to tear and twist off a half a dozen sticky sheets from your disposable roller. 3. Precise rolling of a large area If you don¡¯t have time to pore over every inch of your interview suit with the tiny lint roller you have on hand before you leave, a larger roller that covers more surface area will pack a stronger punch, leaving you ample time to finish your skincare routine before jetting out the door. Is Your Business Using the Right Packaging Tape? There are two primary types of packing tape that are used to seal cartons: plastic pressure-sensitive tape and paper water-activated tape. Each has different physical properties, methods of application, appearance, and performance. It is important that companies go beyond simple decision drivers like cost and availability, and consider how these attributes can impact their operations.Plastic Pressure-Sensitive Tape Plastic pressure-sensitive tape (PST) is what is referred to as a ¡°surface mount¡± type of tape. This carton sealing tape is manufactured by applying a dry adhesive to a plastic film. Both the adhesive, which can have many different strength formulations, and the film, which comes in a variety of widths, are petroleum-based materials. Pressure-sensitive tape is generally applied with a hand-held ¡°tape gun.¡± The pressure applied after the tape is dispensed, typically with the fingers or palm as a follow up, causes the tape to adhere to the surface of the carton. Plastic pressure-sensitive tape can be further divided into moving tape and shipping tape or packaging tape. Moving Tape Moving tape generally does not have to be as strong or adhere as well as shipping tape for a few reasons. First, cartons used in a move from one location to another tend to be handled fewer times than product shipments ¨C potentially just being carried onto a moving truck at the point of origin and off the truck at the destination ¨C so the tape has to endure less stress. Second, there is minimal risk of theft during a move, as cartons tend to be in the care of the same crew from start to finish. And finally, the person who receives the carton is often the one who sealed it. Consequently, there are not many negative repercussions if the condition of the seal is not optimal on arrival. What is electrical tape made of? The key properties of a reliable and trustworthy electrical insulating tape are that it must: act as an effective insulator against electricity, protecting circuitry and users by not conducting current easily be heat-resistant and fireproof to a reasonable degree for the application it¡¯s being used in be flexible, user-friendly and easy to apply to a range of wires, circuits and connections (often in relatively tight spaces) By far the most common material for electrical tape these days is vinyl, but we¡¯ll investigate more materials and their uses in a later section. For now, we¡¯ll take a closer look at some of the general properties of insulating tape listed above, and how best to use it to make the most of those key attributes. Does electrical tape conduct electricity? When used properly, electrical tape should act as an insulator - that is to say, it should protect against transfer of any electrical current passing through the wires to people or components potentially coming into contact with them. As such, properly rated and applied insulating tape should NOT conduct electricity. How to use electrical insulation tape Electrical tape is most commonly used in DIY applications for making repairs and joins to smaller wires. As we¡¯ll outline in more detail below, it should not be used for major repairs to very badly damaged wires, or on its own for creating permanent connections in junction boxes, light switches, or wiring outlets. In these sorts of high-demand, potentially high-temperature environments, insulating tape should only be used in conjunction with purpose-made wire nuts and other connector tools for a safer and more secure fix. Furthermore, electrical tape shouldn¡¯t be used as a standalone repair for damaged or unspliced wires in close proximity to soft furnishings or other flammable materials Can electrical tape catch fire? Although most reputable brands of electrical tape will have decent thermal properties (generally to cope with temperatures up to around 80 degrees Celsius), many varieties of insulation tape are indeed flammable if they¡¯re allowed to get hot enough. The likelihood of combustion is usually reasonably low if it¡¯s used sensibly and in the environment for which it was designed, but this will depend entirely on the application in question and the type of tape being used. Several varieties of electrical insulating tape have much more advanced heat-resistant properties than others. We¡¯ll highlight some of the more specialised types in subsequent sections. What can I use instead of electrical tape? There are various alternatives to electrical tape available, with the most popular options including wire connectors (or ¡®wire nuts¡¯) and heat-shrink tubing. Wire nuts are typically insulated plastic caps with internal threading that are designed to be twisted on to the ends of stripped wires. Heat shrinks are very commonly found on wires in smaller electrical components and circuits, but they¡¯re not usually used in household or industrial applications where the wire gauge tends to be much larger. Other types of adhesive tapes are not generally recommended as a substitute for electrical tape when in direct contact with wiring or circuitry, as they¡¯re designed for other applications and tend to lack sufficient thermal or insulating properties for electrical use, which can mean they quickly become unsafe if deployed incorrectly. Can you use electrical tape to insulate wire? One of the main purposes and most common uses of electrical tape worldwide is to insulate and protect wires and other connections. However, it¡¯s worth noting that in many applications, simply twisting wires together and sealing with electrical tape alone is deemed an unsuitable splicing method for meeting stringent safety standards. Wire nuts are often required in addition to insulating tape for achieving a fully code-compliant setup, so always check any regulations that might apply to the job in question. Furthermore, always be aware that despite the impressive dielectric performance of many purpose-manufactured electrical tapes, very few materials are always 100% non-conductive under the right combination of circumstances. Given enough voltage and current, a short enough path to ground and in the right/wrong environmental conditions, even the most specialised electrical tape types could potentially conduct enough current to cause serious harm. Be vigilant of the potential limitations of insulating tapes when used incorrectly or unsafely, and always shut down all circuits to the fullest extent possible before commencing any kind of repair or maintenance work on them. Electrical Tape vs Duct Tape It¡¯s very important, when dealing with electrical circuitry, to acknowledge and understand the key differences between an electrical tape and duct tape: Duct tape is a widely available pressure-sensitive hybrid sticky tape, generally made from a cloth backing coated with a thin layer of polyethylene or similar flexible plastic The main aim of duct tape is to provide a flexible high-tack layer that will adhere reasonably well to a very wide range of surfaces, and provide a degree of moisture resistance (although it is not technically ¡®waterproof¡¯ to any significant degree) Although it may technically offer slightly more protection against exposed wires than no covering at all, cloth duct tape is NOT an electrical insulating material and is entirely unsuitable for proper protection against live current Duct tape is flammable if allowed to heat up to any significant extent Duct tape is not especially durable and will degrade relatively quickly in adverse conditions (ironically, it¡¯s not especially suitable for duct work for this reason) when compared to most specialist electrical tapes Electrical tape is generally made of a stretchy vinyl/PVC material designed to offer better insulation against current While all tapes will eventually shift or degrade in especially challenging environments, proper electrical insulating tape from a reputable brand (such as 3M) tends to perform far better in the long-run against adverse weather conditions, changing temperatures, moisture ingress and chemical corrosion Is duct tape safe to use as electrical tape? As we can see from the bullet points above, duct tape is a multi-purpose utility product and is absolutely NOT a suitable substitute for purpose-made insulating tapes where electricity is concerned. Electrical tape is specifically designed and produced for meeting the day-to-day needs of electricians, and is the only appropriate choice when an adhesive tape is required in an electrical context - duct tape, or any other kind of adhesive tape for that matter, will not do the job safely. Different types of electrical insulation tape, colours, materials, and their uses. There are a large number of electrical tape types sold on today¡¯s market, with a wide variety of intended uses, key attributes, materials, colours and sizes on offer. As with most such products, the best kind to use will be entirely dependent on the scenario and the job you expect it to perform. In this section, we¡¯ll go over some of the different kinds of electrical tape and what sorts of applications they¡¯re most commonly found in. Titanium Forgings Shapes Forgings refer to products manufactured by the process of shaping metal utilizing compressive forces. The compressive forces used are generally delivered via pressing, pounding, or squeezing under great pressure. Although there are many different kinds of forging processes available, they can be grouped into three main classes: Forging produces pieces that are stronger than an equivalent cast or machined part. As the metal is shaped during the forging process, the internal grain deforms to follow the general shape of the part. This results in a grain that is continuous throughout the part, resulting in its high strength characteristics. Titanium forgings are broadly classified as either cold, warm or hot forgings, according to the temperature at which the processing is performed. Iron and steel are nearly always hot forged, which prevents the work hardening that would result from cold forging. Work hardening increases the difficulty of performing secondary machining operations on the metal pieces. When work hardening is desired, other methods of hardening, most notably heat treating, may be applied to the piece. Alloys such as aluminum and titanium that are amenable to precipitation hardening can be hot forged, followed by hardening. Because of their high strength, forgings are almost always used where reliability and human safety are critical such as in the aerospace, automotive, ship building, oil drilling, engine and petrochemical industries.

TITANIUM POWDER Titanium powder has long been used as an alloying additive for a variety of applications. Recently, technological advances in the production and use of titanium powder have opened doors into many fields including powder metallurgy, thermal spray, laser cladding, metal injection molding, and additive manufacturing. AmeriTi Manufacturing produces titanium powder using the hydride-dehydride (HDH) process. This method uses hydrogen to make the titanium brittle enough to crush and perform initial sizing. Hydrogen is then removed under vacuum followed by final sizing to customer specifications. This process creates a final particle morphology described as blocky or angular. AMC also has the capability to deoxidize titanium alloy powders. Titanium is extremely reactive with oxygen causing it to inevitably increase in oxygen throughout the powder manufacturing process. Our patented deoxidation process allows for possible oxygen levels below 1000 PPM, which is necessary for grades such as Ti 6Al-4V ELI. Deoxidation services are performed on AmeriTi produced titanium powder, but is also available as a toll processing service. Using this process, AmeriTi is able to produce both commercially pure and alloyed titanium powder in a wide range of particle sizes. Screening and blending processes ensure accurate sizing to customer specifications. Advanced process controls and in-process testing allow for consistent particle size distributions and morphology from lot to lot. Introduction Titanium is a transition metal with a white-silvery metallic appearance. Titanium material is a lustrous, strong metal that exhibits good resistance to atmospheric corrosion. The atomic number of titanium is 22 and it belongs to the d-block, period 4, group 4 of the periodic table. Pure titanium is insoluble in water but soluble in concentrated acids. Titanium is the ninth most abundant metal available on earth¡¯s crust; it is present in most igneous rocks and their sediments. Some of the minerals of titanium are illemenite, rutile, brookite, titanite and anatase. These minerals are primarily distributed in West Australia, Canada, Norway and Ukraine. It is low in toxicity, but the powder form of titanium is an explosion hazard. Applications The following are the application areas of titanium: Pigments, additives and coatings Aerospace and marine Industrial Consumer and architecture Jewellery Medical Nuclear waste storage Bike frames aren¡¯t made from pure titanium. Instead, they are made from a titanium alloy. The titanium used to build bicycle frames is typically alloyed with aluminum and vanadium. Varying levels of each element are used to change the physical properties of the finished alloy. Alloying titanium improves strength and durability and reduces the weight of the frame. Many framebuilders market their titanium tubing as ¡®aerospace-grade¡¯. The most common type of tubing used to build titanium bicycles is called 3Al-2.5V. This is titanium that is alloyed with 3% aluminum and 2.5% vanadium. Another common titanium alloy is 6Al-4V. This is a harder alloy that is often found on higher-end bikes. Because it is harder to work with and more expensive, 6Al-4V is sometimes used to make smaller parts such as the head tube or dropouts. Titanium frame tubes can be butted or straight gauge. Butted tubes are thinner in the middle and thicker on the ends. This reduces the weight of the tubes while maintaining strength. Some titanium frame manufactures don¡¯t offer butted frames because butted titanium tubes are harder to work with. This makes it more difficult for the framebuilder to build the bike to your exact specifications. Also, titanium tubes are pretty light so the weight savings is minimal. Titanium tubes are usually cold drawn into shape. These days, frame builders can also shape titanium bikes with a process called hydroforming. This process involves placing the frame tubes in a mold then injecting the mold with fluid at incredibly high pressures. The tubes form into the mold. Hydroforming can be used to fine-tune the tube shapes to optimize the frame for stiffness, weight, or aerodynamics. This can also help design frames with internal cable routing. Titanium frame tubes do not have to be round. After the frame tubes are shaped, they are welded together. The most common type of welding used to bond titanium frames is TIG welding. Titanium is a notoriously difficult metal to weld well. The main reason is that titanium reacts with oxygen. It is also sensitive to contamination. Welding titanium is a labor-intensive process. To learn about the welding process, check out this interesting article. The fabrication and electrochemical properties of a 3D printed titanium electrode array are described. The array comprises 25 round cylinders (0.015 cm radius, 0.3 cm high) that are evenly separated on a 0.48 ¡Á 0.48 cm square porous base (total geometric area of 1.32 cm2). The electrochemically active surface area consists of fused titanium particles and exhibits a large roughness factor ¡Ö17. In acidic, oxygenated solution, the available potential window is from ~-0.3 to +1.2 V. The voltammetric response of ferrocyanide is quasi-reversible arising from slow heterogeneous electron transfer due to the presence of a native/oxidatively formed oxide. Unlike other metal electrodes, both [Ru(bpy)3]1+ and [Ru(bpy)3]3+ can be created in aqueous solutions which enables electrochemiluminescence to be generated by an annihilation mechanism. Depositing a thin gold layer significantly increases the standard heterogeneous electron transfer rate constant, ko, by a factor of ~80 to a value of 8.0 ¡À 0.4 ¡Á 10?3 cm s?1 and the voltammetry of ferrocyanide becomes reversible. The titanium and gold coated arrays generate electrochemiluminescence using tri-propyl amine as a co-reactant. However, the intensity of the gold-coated array is between 30 (high scan rate) and 100-fold (slow scan rates) higher at the gold coated arrays. Moreover, while the voltammetry of the luminophore is dominated by semi-infinite linear diffusion, the ECL response is significantly influenced by radial diffusion to the individual microcylinders of the array. As a professional manufacturer, we provide several titanium products.  ICQ Nummer   Registriert am: 10.11.2022 Zuletzt Online 10.11.2022 Letzte Aktivität: noch keine Aktivitäten
