Cent of carbon fiber grade differs for T300-T1000, grade of bigger carbon fiber also exceeds the number tall. Among them every grade is divided again for 1K, 3K, 6K, 12K, 24K, 48K, 60K, 80K, 1k delegate has 1000 monofilament in each bundles of carbon fiber, 80k delegate has 80000 monofilament in each bundles of carbon fiber. Generally speaking, small are called by all under 12k bundle of carbon fiber, be called carbon fiber of ” of “ aerospace class again, 12k above is called big bundle of carbon fiber, or industrial level carbon fiber. Article place introduces because size is larger,draw crowded composite material, the selection is so big bundle of carbon fiber. In macerate operation, the accurately quantity in chamfer of preexistence colophony macerate enters colophony of hot solid sex and solidify agent to wait, press agent of colophony, solidify and agent of drawing of patterns certain quality than mixing, mix is even chamfer of infuse colophony macerate. General colophony manufacturer can give out of directiveness deserve to compare, among them a few inside agent of drawing of patterns is indispensable, prevent to shape in hot solid jam in the process mould. In whole macerate process, fiber soak wants complete, should not put in dry fiber, dry fibrous existence can be brought about pull crowded products give birth to blemish, parameter of a when control rate of carbon fiber soak vital technology is the viscosity of colophony system, this viscosity becomes initiative viscosity, its size is concerned with colophony itself not only, and concern with additive, temperature. Besides initiative viscosity, effect of carbon fiber soak returns the working status with the carbon fiber in temperature of the resinous when infiltration time, soak and macerate chamfer to concern, generally speaking, gave initiative viscosity, status of carbon fiber job is normal, immersion time is longer, colophony temperature is elevatory, all can improve fiber soak rate. Divide this beyond, still need to notice resinous viscosity wants to maintain the limits with be in certain, indoor temperature should have been controlled, if day air temperature spends low word, can consider glue chamfer to add lukewarm, in order to make sure colophony can enter mould mouth smoothly as carbon fiber, won't be squeezed to come out, also won't jam; As a result of big silk bundle every bundles of carbon fiber in carbon fiber is more, always should notice colophony is right the infiltration circumstance of carbon fiber monofilament, not only carbon fiber silk bundle the surface should have better soak, assure carbon fiber silk even bundle interior also can infiltrate sufficient, can cause in-house defect otherwise, influence eventually the function of the product. Generally speaking, pull crowded process cent to be region of 3 thermal treatment zone. It is warm-up area first, action is to be response of below one region to prepare; It is gel area next, in this area, colophony produces solidify cross-linking and generation changes, from ropy condition change is gel condition; Constant temperature area is after, prevent temperature to change suddenly make composite material produces crackle. The temperature control of buccal model area matters to the quality that pulls crowded birth rate and product. Temperature pilot key is to make stock solidify rate and profile drawing speed consistent, in the meantime, assure to heat even even, stock everywhere solidify rate agrees as far as possible. Buccal model place uses board formula normally or barrel type contacts heater. Current high frequency warm-up and the problem that high frequency solidify solved fast solidify the colophony to different type, the temperature of 3 area each are not identical, overall for, among them rule is ordinal increase. On the other hand, be aimed at the composite material of different measurement, the temperature of 3 area also changes somewhat, size is for instance large, thicker pull crowded lever, solidify temperature wants temperature of solidify of prep above resinous, because temperature is the surface from composite material,deliver upcountry, such ability make the colophony inside complete solidify, be united in wedlock together well with carbon fiber. Pull crowded shape to use clip to hold draw gear normally, this device has two pairs of in-house appearance and the furniture that make a photograph match, pull crowded content to be in clamping apparatus among, clamping apparatus relies on to compress air to get on next opening to shut, installation of this clamping apparatus is being propped up on, clip of drive of hydraulic pressure oil cylinder holds device to make reciprocate, to do not mar the appearance that plays crowded thing, clamping apparatus and pull crowded content to contact constant line with polyurethane material. Help the issue of the solidify after the control of crowded craft still should consider, to large make particularly important. Accordingly no matter the rate in successive processing is much slower, very difficult also generation produces in that way solidify condition like intermittence. Pull crowded shape later period solidify is simple means is to install to heat solidify room, and what more uses is hot cell is increased detachedly in, with the solidify after coming, assure solidify degree. 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.
