ова горе е корисно но за брзо чистење дрвени површини покорисно е чистење со компресор [1][2] сепак за прецизно отстранување боја најдобра опција се разредувачи http://en.wikipedia.org/wiki/Paint_stripper#Types_of_chemical_paint_removers

што е до чистење фарби од метални површини најдобро е да се оди со пескарење со оглед дека многу побрзо оди од шмирглање со брусилица или со метална четка, има и хемиски методи но за тоа немам баш абер

Nano Coatings Paint Green Future - John Gartner 02.10.06 

New spray-on, nanotech coatings could keep iPod screens from scratching, make paper products waterproof and perform other minor modern miracles.

And because they are cheaper, easier to apply and more environmentally friendly than substances currently in use, nanotechnology-based coatings could replace many of today's industrial paints and coatings.

The nano coatings, "liquid solids" composed of extremely tiny particles, possess unique characteristics -- like extreme flexibility, easy adhesion and resistance to corrosion and microbial growth -- that could profoundly change the manufacturing process.

Sally Ramsey, co-founder and chief chemist of Ecology Coatings, began exploring the costs and potential environmental benefits of nano coatings in 2003. She used nano-sized particles of mineral oxides to create waterproof coatings for paper at half the cost of synthetic paper. Derivative materials could be used to produce waterproof cardboard boxes, or integrated into building materials such as drywall to prevent mold from growing if it becomes wet, Ramsey said.

The wonder coatings also might make small video screens on electronic devices such as iPods and mobile phones more durable.

"Abrasion-resistance and scratch-resistance is very much enhanced" when the nano coating is applied, according to Ramsey, and surface hardness is strengthened without losing clarity.

A similar nano coating, licensed from Ecology Coatings by chemical giant DuPont, could revolutionize the auto parts industry when it is commercialized, possibly as early as this year.

DuPont hopes to produce nano paint that seals and protects automotive components, greatly reducing the environmental impact of producing cars by slashing the amount of energy and materials needed. The nano-based coating could radically alter the time-consuming and costly process of applying coatings to auto parts.

The nano particles are small enough to be applied using conventional spraying equipment, Ramsey said, and the nanotech coating can be cured simply by exposing the surface of the auto parts to ultraviolet light for 10 seconds or less.

"After the UV (light) hits it, it becomes a thin sheet of plastic," she said. UV curing, which is completed at room temperature, would replace the standard curing process, which requires placing parts in ovens at temperatures of up to 400 degrees Fahrenheit for as long as 40 minutes.

Because they eliminate the need for hazardous chemicals currently in use, the nano coatings also could save parts manufacturers from getting Environmental Protection Agency permits, tracking emissions and disposing of solvents.

It all adds up to a more ecologically friendly process with a welcome side benefit: lower manufacturing costs.

According to Bob Matheson, technical manager for strategic technology production at DuPont, using Ecology Coatings' nano-based materials could reduce the cost of applying a coating from "a few dimes per article down to 1 cent per article or less."

Shifting to nano-based coatings could also change how auto parts are designed. For instance, engineers could use different materials because they wouldn't have to worry about heat from the manufacturing process melting plastic parts, Matheson said.

"We are in the early stages of a profound industry change," he said.

Matheson said the technology probably would be applied first to "under the hood" parts, such as oil filters or disc brake drums.

DuPont chose products from Ecology Coatings because the technology is cleaner and less energy intensive than other UV-curable coatings, Matheson said. He estimates the technology will reduce the amount of energy used in the coating-application process by 25 percent and reduce materials costs by 75 percent.

However, UV curing requires exposing the entire surface area of the part to the light, which is a limitation. And manufacturing plants would have to be redesigned for the process, replacing rooms engineered to withstand high temperatures with arrays of UV lights, Matheson said.

Paul Uglum, the appearance technology advocate for auto parts company Delphi, said his company is beginning to use some UV-curable paints.

He said heat curing disrupts the manufacturing process. "If you have parts that are in an oven for half an hour, than you have a huge buffer of parts waiting to be finished," he said.

Uglum said the energy saved from switching to UV-curable paints would be significant, since his division of Delphi produces 3.5 million parts per week. The amount of paint used could be reduced by "thousands of gallons," he said.

"Being less energy intensive and more environmentally friendly is a plus," said Charles Griffith, the auto project director at nonprofit environmental group the Ecology Center. Auto parts manufacturers may be attracted to the technology because "if you use non-hazardous materials to start with, then you don't have the same regulatory triggers," he said.

However, because the "state of knowledge about some nano particles is quite immature," Griffith said, "we would need to know about health studies for the potential impacts of these particles."

има интересен новитет кој ко емулзија се нанесува пред фарба, апликативен и за дрво освен бетон

http://www.rustoleum.com/product-catalog/consumer-brands/specialty/magnetic/



сепак ваквата емулзија т.е. primer нема доволно јака привлечност, па заради тоа неопходно е дополнително да се осигураат рамките или преметите со магнетни ленти како би се зголемила носивоста пр. со MaxField Polymagnets

од истиот батка уште една екстра ујдурма, добар абер за репринт на залепени тапети претходно испеглани подобно предочено во пост #21 погоре

...

That’s where the UCR prototype rewritable paper is different. Not only is it able to be printed upon, completely erased, and subsequently reprinted, it also takes advantage of the unique chemical properties of commercial inks known as redox dyes. These dyes are applied once and then, when a photomasked template is overlaid and the combination exposed to ultraviolet light, the uncovered portions are photo-bleached away, leaving behind the print. To reuse the sheet and erase the print it is then exposed to heat of around 115 °C (239 °F) and a blank sheet is once more created.

"Even for this kind of paper, heating to 115 °C poses no problem. In conventional laser printers, paper is already heated to 200 °C in order to get toner particles to bond to the paper surface," said Professor Yadong Yin, professor of chemistry at UCR. "This rewritable paper does not require additional inks for printing, making it both economically and environmentally viable. It represents an attractive alternative to regular paper in meeting the increasing global needs for sustainability and environmental conservation."

не дека нема сф новитети, но кој и кога би видел аир од денешниве генерации, еве инспиративен новитет за конвертибилни шасии, намештај или облека

http://www.uni-kiel.de/zoologie/gorb/2009_gorb_labor_and_more_UK.pdf

19.11.2007 - Инсектите - инспирација за најефикасната леплива лента


Научниците од германскиот институт „Макс Планк“ и од американскиот универзитет „Кејс вестерн ризрв“ создале структурен материјал што е двојно полеплив од стандардните селотејпи .

Новиот адхезив не содржи лепило, а може да се користи и на прашливи површини и да се измие со сапун и со вода. Научниците го нарекле „селотејп на инсектите“, зашто неговите лепливи својства се добиени благодарение на анализата на микроструктурата од „шепите“ на повеќе од 300 вида стоногалки.

Луѓето со векови сонуваат за можноста да се движат по ѕидовите и таваните како инсектите или гуштерите. Сега научниците откриле дека, според начинот на кој се прицврстуваат на површината по која се движат, животните може да се поделат во две групи: оние што го прават тоа со помош на мазни перничиња и оние што се „прилепуваат“ со помош на ситните влакненца на површината на „шепите“. И едните и другите можат да му се приспособат на релјефот на површината на која се лепат.

Научниците ја проучувале втората група, чии претставници се пораспространети, и утврдиле дека влакненцата на нивните „шепи“ се многу густо поставени и според должината варираат од неколку микрометри до неколку милиметри. Се покажало дека таквата разновидност на влакненцата овозможува максимално прилепување на површината. Создавајќи материјал со многу влакненца, научниците добиле уште една предност: отпорност на правот, чии честички едноставно „тонат“ во просторот меѓу влакненцата. Краевите на влакненцата, кои потсетуваат на печурки, и' овозможуваат на новата леплива лента да се залепи и на рапава површина, дури и ако на неа има дупчиња и пукнатини. Со оглед на тоа дека влакненцата се еластични, лентата може да се употребува повеќекратно.

- Лепливата лента што ја создадовме поседува најсилна лепливост од сите досега создадени лепливи материјали и има најдолг рок на траење (неколку илјади циклуси на адхезија). Ако лентата се извалка или изгуби дел од своите својства, може да се испере со сапуница, со што ќе и' се врати лепливоста.

Јачината на прилепување, т.е. силата на адхезија на инсектите, пајаците и гуштерите на рамна стаклена површина изнесува околу 100 килопаскали, а овој материјал постигнува сила од 60 килопаскали - објаснува Станислав Горб, еден од авторите на студијата.

Paint it black hole: World’s darkest material now available as spray paint

The world’s blackest material, Vantablack, is now available in spray paint form, expanding its capabilities beyond the space and defense industries into the imagination of the commercial sector to turn 3D objects into non-reflective 2D “black holes.”

The spray on version, Vantablack S-VIS will be easier to apply than the original and can be used on larger, more complex objects made up of a wider variety of materials.Vantablack, which is made from carbon nanotubes, was created two years ago by UK company Surrey NanoSystems and traps 99.965 percent of incoming light - making three dimensional objects appear two dimensional



The spray on version captures 99.8 percent of ultraviolet, visible and infrared light and is 17 times less reflective than the super-black paint used in the Hubble telescope, according to Surrey Nanosystems.

While Vantablack was originally created to coat optical components in the space and defense industry the spray will open the possibilities of use to cameras and luxury goods.

Vantablack S-VIS however doesn’t hold up well to abrasion and needs to have some sort of protection over it. Using it isn’t as simple as applying conventional spray paint as it requires a number of “pre- and post-application steps.”

And unfortunately it’s not a case of buying a can at your local hardware store and transforming your car into a 2D, blacker than black, driving machine. Surrey NanoSystems will apply Vantablack S-VIS for clients or they can license the technology for their own production facilities.
