Craft of respecting vacuum perfusion, the likelihood that everybody thinks of above all is the application of hull and wind- driven lamina. But besides ocean and wind energy, other market also begins to turn to this kind of production method to make product —— suffer fully for instance fix eyes upon “ postcard: 9/11” monument. The Sidadu that this monument is located in new York island, the dweller that souvenir makes a surprise attack in 9/11 horror and died in case of explosion of world trade center 1993. This monument has the 40 feet of two independence tall wall that is similar to wing. Topping white wall is designed with concrete at first, but architect and engineer convert GFRP will make solid arc face plate, in order to resist sea wind and seawater. Monument is an example of VIP only, VIP also is weighed for vacuum colophony perfusion. This workmanship is highlighted in 90 time place, TPI technology obtained Xi Manfu to add up to material colophony perfusion to shape at that time craft (the patent of SCRIMP) . The invention of this technology is to satisfy the slashing requirement of American naval project. Thenceforth rises, company of relevant composite material begins to change VIP to craft, this is the craft shutting a model that a kind of use vacuum presses plywood of layer of infuse of force general colophony, apply to mix from the train ballproof board all things to swimming-pool and industrial component. The product of company of American Polynt composite material and benefit of assorted of applied expert A respecting of · Deng Ken, perfusion colophony had existed a few years, but this industry is being improved all the time and material also is increasing ceaselessly.

Advantage is great

Vacuum perfusion craft has a lot of advantage, among them a lot of already was people place hep. Shape with open mode craft photograph is compared, VIP can provide high quality, more consistent component. But also have a few not quite the merit that humanness knows. Because colophony content drops, fiber scale rises as vacuum perfusion. Fiber assumed all jobs now, this makes a part more hard. This makes people OK consideration sandwich technology, this is in the likelihood was impossible past. Final, this also will make a lighter, stronger product. The consistency of the spare parts results from the high control that vacuum perfusion craft offers, this is to open type to shape craft cannot come true. Senior personage holds advisory division concurrently to install heart intense • inside course of study Kekuite answers the cooperates with company of a large shipbuilding experience before recall is old, this company most begin to support distrustful attitude to VIP. Kekuite respecting, they claim to use open mode to shape craft can control hull weight difference the 5% less than in hull gross weight. But when persuade them to have audit when me and undertaking saying to weigh to a few hull, their average weight difference never under 10% . If you have the body of a ship with a 10000 heavy pounds, that is 1000 pounds. This company turns and use VIP technology. This new technology studies in the job as technical personnel, first change is in on average 100 arrive between 250 pounds. Below the help of experienced technical personnel, the average difference of a hull that hefts 2000 pounds can fall to 25 to 50 pounds. In addition, consistency still has another profit. Become when the spare parts is more consistent, in constructional later period, they are assembled together with respect to easier combination. But the improvement that the advantage with the most distinct perhaps VIP is working environment, in current commercial environment, appear particularly important. The working environment that improves a plant conduces to a company drawing stabler, more high grade able-bodied person, and can better tarry employee. Compare with photograph of spray of open mode mould, use enclosed craft eliminated VOC and HAP almost discharge, this can help a company reduce superintendency cost. Another advantage of VIP was to reduce a mould to take up periodic time, this also produced an effect to labour force, this caused the attention that seeks company of seed profit operation.

Of VIP evolve

Although vacuum perfusion craft is a mature technology, but the space that still has progress. The change of the market says with its is a revolution, be inferior to saying is one kind evolves. New buildup material is had taller osmotic with fluidity, have the stuff of applicable and different technology. For example, will come off the layer leaves model film and the assorted product that medium of going from place to place combines together, this decreased installation and disassemble its labour force. One of challenges that the supplier had developed other product to overcome VIP to be faced with —— makes class A appearance. Use VIP craft, fiber content should be gotten high much, because this fiber nears mould surface more, this can be brought about be out of shape or fiber print through. To answer this one challenge, there was colophony of small section plane now, can give you better appearance and lower exothermic. Core material also undertook adjustment. For example, the supplier raised groove in core material, in order to eliminate fluid medium cost. A few equipment, if wear platinic applied center, can apply distributing as outline cut and colophony implement groove. In addition, auxiliary things also had development, had more off-the-peg article. In addition, the material —— outside the mould feed pipe path and vacuum conduit —— are for instance easier now the material with prefab bring into contact with. As the improvement of material, enter the opportunity of the market also is increasing beyond ocean and wind energy. Tool is an application that manufacturer needs to consider. Will close as more and more people the production process that the mould brings into them, they also realize also can use it to create a pattern. Use colophony perfusion makes fibre glass mould and component of production of use colophony perfusion have identical advantage. Can improve mould quality for example. Colophony perfusion mould is OK quickly compose builds lamination structure and clip core structure, be in the place of need specific to load, offer structure of splendid solidify of layer pressing plate and utmost ground to reduce air gap at the same time, it is especially all round core material. After the potential that realises the mould is made, company of American Polynt composite material expanded its Optiplus® product line, include system of perfusion mould colophony. Compare with photograph of system of open mode mould, it has the outstanding size control, advantage that improves exterior quality and higher Bo fine content. This system still offerred better hear resistance, this conduces to lengthen mould life expectancy. Final application domain also is increasing. Aerospace is a market that witnesses VIP growth. This market realized the gain of this one process a few years ago. However, material, auxiliary product, skill and knowledge are far insufficient still. Present tense machine is already mature. The expert expresses, the infuse of spaceflight domain wants than what people realizes much. It is used at seat back of a chair to mix other must be high-powered, the product of low weight. Additional, traffic and recreational car market also prepare to receive VIP. But this is really very scabrous problem, because be in this industry, the tradition uses data or give priority to with the metal, but the advantage that manufacturer had seen composite material. They can get resembling lorry sidewall and floor such chunk material, these material are to include core capable person, they are likewise so hard.

Expert proposal

Basically consider the following proposal: L abides by relevant law: Amount to law is the equation that fluid of a control passes porous material to flow on the west, apply to VIP. Amount to law makes clear on the west, inside the viscosity of osmotic, resinous of velocity of flow and material and modular antrum press difference to concern. ” uses this process when you when, you must consider these principles. L perfusion designs: The taller fiber in VIP can fetch higher intensity and lighter weight with colophony comparing, can reduce thickness of layer pressing plate thereby. But this may have a problem. When you reduce thickness, you reduced the stiffness that defy a turn. People is added normally enhance material to make up for difference, but the density that enhances material is resinous commonly 2 times. So, you may receive a heavier share finally. This is the place that you need to redesign the layer pressing plate that is used at perfusion, perhaps consider to add core capable person. L establishs a detailed account and abide by it: Although VIP is very simple, but a few crucial step need to notice. Safeguard detailed list to will conduce to ensure make just abide by these detailed list. L checks everything: This includes to test equipment, in order to ensure the job of vavuum pump, test mould, in order to ensure it is of airtight, test colophony, such you know gel time and viscosity, check a pressing plate, the rate of going from place to place that sees it and distance are waited a moment. No matter be new product, new colophony or new tissue, before beginning perfusion, you want to know its property. Weigh the cost photograph of fiasco to compare with, spending the time on test and study is negligible
