VexProxy
is a rotating IPV6, Residential, Mobile proxy network which enables users to gather any data from the web using a pool of millions of proxies.

What are IPV6 proxies and what are they used for?

An IPv6 proxy is a device or software that sits on the edge of a network to translate IPv4 (Internet Protocol version 4) to IPv6.
They're tipically used for Captcha Solving, Google Crawling, Data Gathering, Data Analyzing, Emulating Views.
 
What are rotating residential proxies?
A rotating or a Backconnect proxy relies on an entire network of proxies, rotating between them either periodically or randomly, thus better protecting your privacy and allowing to generate a high number of search requests. Your connection and IP is being rotated with every action you take, which prevents data footprints, ensures extra security and lower ban-rate.

Introduce yourself / Zijn er nog aanwezigen?
« Last post by Ron-Looij on 9 April 2021, 14:57:26 »
Ik ben al een paar jaar actief (lezer) op dit forum, maar krijg het vermoeden dat er weinig anderen actief zijn. Klopt dit? Ik zou natuurlijk het liefste willen dat mijn ongelijk bewezen wordt, maar ik heb weleens op een topic gereageerd maar nooit reactie op mijn vraag mogen ontvangen.
Om mijzelf voor te stellen: Ik ben Ron Looijesteijn, geboren in 1986, heb na mijn MBO werktuigbouwkunde HBO Technische Bedrijfskunde gedaan, ben werkzaam in de constructie en ik zou in de toekomst graag meer in het titanium doen. Ik heb ongeveer 10 jaar geleden al eens een uitlaat gemaakt van voorgebogen bochten, maar met mijn huidige kennis had ik dat zeker anders gedaan!
De uitlaten die ik dan al zou maken/repareren zijn uitsluitend voor motorfietsen bedoelt.

Tantalum / How to get the high purity tantalum?
« Last post by Tiarticle on 10 September 2018, 09:15:54 »
Tantalum belongs to the refractory metal group and is widely used as a minor component in alloys. Its chemical properties are excellent, no matter whether it is cold or hot, it does not react with hydrochloric acid, concentrated nitric acid and “Aqua regia”. Its chemical inertness and relatively low price make it a good alternative to platinum. In addition, tantalum is also highly resistant to corrosion, but its corrosion resistance is not due to tantalum itself, but due to the formation of a stable tantalum pentoxide (Ta2O5) protective film on its surface. Tantalum can be used to manufacture evaporation vessels, as well as tubes, rectifiers, and electrolytic capacitors.

Tantalum, always together with the chemically similar niobium, is usually found in the mineral groups of tantalite, columbite and coltan (a mix of columbite and tantalite, though not recognised as a separate mineral species). So, how to get the tantalum of high purity?

1 Tantalum powder can be obtained by metal thermal reduction (sodium thermal reduction) method. The potassium fluotantalate is reduced with sodium metal under an inert atmosphere: K2TaF7 + 5Na-→Ta+5NaF+2KF. The reaction was carried out in a stainless steel tank, and the reaction was quickly completed when the temperature was heated to 900 °C. The powder prepared by this method has irregular grain shape and fine particle size, and is suitable for making tantalum capacitors.

2 The tantalum powder can also be obtained by molten salt electrolysis: a molten salt of a mixture of potassium fluoroantimonate, potassium fluoride and potassium chloride is used as an electrolyte, and tantalum pentoxide (Ta2O5) is dissolved therein and electrolyzed at 750 °C. This method can obtain a bismuth powder having a purity of 99.8 to 99.9%.

3 Tantalum can also be obtained by carbothermal reduction of Ta2O5. The reduction is generally carried out in two steps: first, a mixture of a certain ratio of Ta2O5 and carbon is made into tantalum carbide (TaC) at 1800 to 2000 ° C in a hydrogen atmosphere. Then, TaC and Ta2O5 are prepared into a mixture in a certain ratio, and reduced to tantalum in a vacuum.

4 Tantalum can also be obtained by thermal decomposition or hydrogen reduction of chloride. The dense metal crucible can be prepared by vacuum arc, electron beam, plasma beam melting or powder metallurgy.

Titanium is corrosion-resistant, so everyone usually thinks it is an inert metal. On the contrary, titanium is actually a very active metal. It has a low equilibrium potential and a high degree of thermodynamic corrosion in the medium, but it is actually a lot. Titanium in the medium is very stable, especially titanium can't react with liquid and solid, and it can't be combined. Even Wangshui can't help it. However, titanium reacts very strongly to gas. Titanium likes nitrogen, oxygen and hydrogen. Many gases such as carbon dioxide, water vapor, and methane are combined. This characteristic of titanium, which has a great affinity with gas, is widely used in our lives.

The most common one is the fireworks that are released during the holiday season. The contribution of titanium here is not small. When titanium powder and oxygen are rapidly combined to burn, they can produce intense heat and brilliance. This feature of titanium not only enhances the atmosphere of people's joy, but also can be used in the military. The dazzling light of the signal flare is the combination of titanium and oxygen. In daily lighting, such as the arc lamp, the right amount of titanium is added. The compound can increase its brightness. The strong absorption of titanium's affinity for air removes air and creates a vacuum. For example, using a vacuum pump made of titanium, the air can be pumped clean and free. In the metallurgical industry, adding a small amount of titanium to molten steel can “eat” the gas and impurities inside, can play a good role in deoxidation and nitrogen removal, and can eliminate the harmful effects of sulfur, thereby improving the mechanical properties of steel. And corrosion resistance.

Titanium production / Titanium plate titanium alloy material introduction
« Last post by Tiarticle on 20 August 2018, 10:52:44 »
Titanium plate for glasses, referred to as glasses plate, is a plate made of titanium material, which is divided into pure titanium glasses plate, titanium alloy glasses plate and memory titanium glasses plate.

Titanium has good corrosion resistance and is similar to platinum, and its mechanical properties are excellent. Used in the glasses frame is light, flexible, corrosion resistant and so on.

However, titanium and titanium alloy glasses are expensive to produce, are highly demanding in buckling, stamping, cutting, and welding, are not easily soldered and plated, and must be completed in a vacuum. Therefore, the price is relatively expensive, and it is only used for medium and high-end frames.

As a new type of eyewear material, titanium metal has been favored by more and more consumers because of its advantages of lightness, corrosion resistance, anti-allergy and high strength. With the development of titanium materials, the processing technology has become more and more mature. There are many kinds of titanium-based frames such as pure titanium, B-titanium and memory titanium. Among them, pure titanium material frame purity requirements of 99.9% (excluding gaskets, screws, stipules and leg sleeves), its logo is called PURETITANIUM, or abbreviated as Ti-P. However, some manufacturers have also carried out the above identification on some non-pure titanium or titanium alloy materials, and the consumers have insufficient discriminating ability for pure titanium frames, resulting in the appearance of frames after consumers wear titanium frames. Rust, skin allergies and other phenomena have harmed the interests of consumers. Here are a few simple ways to identify a pure titanium frame.

1. By hand weight, usually the alloy frame has a specific gravity of about 8.9g/cm3, and the pure titanium frame has a specific gravity of about 4.5g/cm3. Since the titanium material has a weight equivalent to half of the alloy frame, it is lighter by hand. This is one of the easiest ways to distinguish between titanium and non-titanium frames.

2. Observe the welding points of the nose support and the nose support bucket. The welding of pure titanium material is vacuum oxygen-free welding. Here, the welding mark is "step" shape, the welding of alloy material is spot welding, and the welding mark is "slope". "This is one of the effective ways to distinguish between titanium and non-titanium frames."

3. Observe whether there is a gasket at the hinge joint. The pure titanium frame should not directly contact titanium and titanium at the hinge part, otherwise the phenomenon of wrinkling at the joint and poor joint of the temple may occur. Usually, two thin shims are placed in the hinge part of the pure titanium frame to separate the upper and lower hinges. Therefore, checking the presence or absence of a shim at the hinge is also a good way to identify if it is a pure titanium frame.

4. Use a magnet to make a magnetic reaction, loosen the frame hinge as much as possible, and use a magnet to attract it under free-moving conditions. If the temple is shaken under the attraction of the magnet, the frame is not pure titanium, otherwise the mirror is The frame may be a pure titanium frame.

The titanium plates used in the frames are divided into three categories, pure titanium; TC4; and B titanium 15333, pure titanium is divided into soft and hard boards, generally soft boards are slightly more expensive than hard boards, soft boards are generally The hardness is required to be 67--80; it can be stamped, and the hardness of the hard board is generally 90-97; it cannot be stamped and can only be cut by wire. The 15333 titanium material used for high-end glasses frames is difficult to process.

The advantages of β titanium as a spectacle frame and eyeglass frame:

Β-titanium alloy is a titanium material which is delayed in cooling at the zero boundary point of titanium to complete β-particles. Its processing technology is higher than pure titanium, which has better strength, fatigue resistance and environmental resistance than pure titanium and other titanium alloys. Corrosion property, shape plasticity, solid solution state, its elastic modulus is about 80GPa, slightly higher than the elastic modulus of titanium-nickel shape memory alloy (about 60 GPa), it has high elastic recovery force (ie The arch wire has no permanent deformation after bending at a large distance. The hardness is low, it is easy to form, and can be bent or formed into a complicated shape without being broken. The spectacle frame made by the lens compensates for the lack of elasticity of the pure titanium frame, the elasticity and the memory characteristics, and the processing performance and welding of the β titanium alloy are excellent, and the spectacle frame and style made by the spectacle frame are more. A new generation of glasses for making materials. Therefore, the frame of β-titanium alloy is popular in the developed countries such as Europe and the United States as a medium-to-high-end decoration and a fashion. It has been widely used in the production of high-grade titanium frames and wire.
