Traditional epoxy resin material already exceeded 30 years in the large-scale application on wind report lamina, apply already very mature, function is reliable. And polyurethane colophony has prime rate to be mixed quickly the advantage with solidify rapid rate, compare epoxy resin, polyurethane material more get used to blade light quantify, large the tide that turn, the expert inside course of study says, period of lamina of polyurethane wind report is coming. of of dominant position of polyurethane resinous performance 1. Fight pressure, colophony of better polyurethane promoted the function such as drawing and exhaustion one-way Bo towing tie substantially of composite material fight control function and transverse drawing function, suit to make large structural member, have better fatigue resistance can. 2. Colophony of taller polyurethane of manufacturing efficiency can shorten perfusion time and solidify time, it is the half of congener epoxy resin about; 3. Waiting for stiffness premise integratedly to drop into this lower low fibrous colophony sucks glue to measure, farther implementation lamina is light quantify. Polyurethane lamina makes technical application, improved the manufacturing efficiency of blade and performance significantly, reduced production cost. Polyurethane resinous application breaks through 1. Division think of achieve associated industry associate to raise 1.5MW successfully in development lamina of fan of system of colophony of new-style high-powered polyurethane, this means the epoxy resin that replaces a tradition with polyurethane on blade material to become a possibility. 2. July 2021 portion, lamina of report of polyurethane wind of long EN156 of times new material starts a quantity formally to produce in dynamical cereal factory, raise a quantity to produce blade to yielded recently. Compare with photograph of traditional material epoxy resin, polyurethane colophony has more superior mechanical performance and fatigue resistance can, perfusion and solidify rate are rapid, processability can be good, organic matter is volatile low, the price is relatively favourable. This year epoxy resin rises in price and wind cable entire industry falls below the big setting of this synergism, the cost advantage of polyurethane also gets revealing. Applied foreground is light quantify and large the trend that changing is fan lamina development, be opposite subsequently the demand of craft is higher and higher also. In addition, the cost pressure of times of wind n price also makes an industry seek the way that new material replaces. Have on big lamina as a result of polyurethane material more apparent replace an advantage, will hold market of big lamina of fan of low wind speed. Rise ceaselessly as what produce the demand such as function of cost, product to blade, of carbon fiber pull crowded shape girder shop put a technology to get study extensively, already was in got domestic and internationally developing, carbon fiber helps the trend that crowded goods will be future. At present domestic company is squeezed about pulling shape consciousness of integral application research and capacity are insufficient, applied dimensions and level, the method of the design and idea, the foundation of material and form a complete set, workmanship and technology all lag behind badly, restricted the development of composite material industry, urgently progress and upgrade. Squeeze to strengthen domestic and international composite material to pull shape the technical communication of craft and market butt joint, advance forward position craft, advanced equipment and applied product development, drive catenary of composite material entire industry to optimize upgrade, study pulls crowded new technology, understanding to draw crowded new facility, master terminal new application, understand thoroughly market new trend, international of scan widely of answer ability network, home of base oneself upon, is on October 2021 27-29 day in Zhejiang? Jia Xingshao opens “2021 international composite material to pull crowded craft to apply height forum and plant site to demonstrate to groom meeting ” . This second conference pulls crowded craft and applied ” to give priority to a problem with “ composite material, kelaosimafei assist do. The conference plans to invite international to play crowded technology expert, help research and development of crowded products company the splendid report that total industry and scholar of expert of terminal application domain make technology and applied photograph union, craft and market phase tie. Session visits the organization the chemical plant of Jia Xingyi body that inspects German brand to overcome Laosimafei, do 4 intelligence change industry of learning understanding composite material 5 large dominant positions moxa chart? The picture is pulled crowded shape systematic whole solution, promote and deepen forum delibrate achievement. Invite sincerely domestic and international composite material to pull expert of crowded craft domain, scholar, entrepreneur and industry colleague to arrive at congress, conspire answer material new tomorrow. Sponsor unit composite material website assist do unit to overcome of of topic for discussion of congress of of of Lao Sima humble 2021 pull squeeze shape technology market report and of analysis of prospective development foreground help crowded technology in, remove dust, retroflexion automatic product line time / place time: On October 27, 2021 - place of 29 days of : Zhejiang fine promote of of relevant item 1. Meeting Wu expends member of network of standard answer ability: 1900 yuan / person, of of person of blame member 3800/ (contain pass of data of all and relevant conference, conference and conference have dinner) notes: Accommodation unites arrangement by meeting Wu group, charge provides for oneself. 2. Meeting Wu cost presses a requirement to be collected ahead of schedule please assign account, meeting Wu group is centralized open bill, data of make out an invoice sends mailbox please: Contact of of Frp@cnfrp.com means signing up: of Yu Zhen connects a telephone call: 186 5346 3667
