Just as its name implies of the material that place core lets composite material become lighter!

Ba Sha wood (common weighs light wood) Balsa 　 item characteristics: 1. Extremely high intensity and hardness (weight compares) . 2. Specific heat is small, impact of be deceived lukewarm change is little. 3. The good performance that fight fire. 4. Beautiful of function of heatproof, sound insulation. 5. The chemical that uses to the need in answer lumber industry has very strong corrosion resistance, for example styrene. 6. Have very good union sex with colophony and adhesive. 7. Suit different answer capable person to manufacture technology, if bag of mould pressing, vacuum, hand is burnt,wait. PVC bubble board 　 is a foundation with vinyl polymer, carry group of perforative balmy acyl amine the alloy foam of the network. The habit calls capable person of core of cross-linking PVC bubble, it is the ideal core material of structure of composite material interlining. This product is integrated and mechanical performance is superior, chemistry is stable, have high sexual price to compare, in wind report, go aboard with water the domain such as a light boat been havinging wide application. △ of 　 of 　 of 40~250kg/m3 of limits of density of △ of 　 of function characteristic 　 is had compare stiffness admirably, than △ of intensity 　 　 fatigue resistance is good, the △ of anti-flammability 　 　 with good △ of 　 of 　 of heat insolation of heat preservation of △ of 　 of impact resistance good 　 is low bibulous rate, not easy be affected with damp be affected with damp, mildew changes the dimension stability with good △ of 　 of 　 of isotropy of 　 　 △ and temperature of craft of △ of 　 of machinability 　 - 240~100 ℃ , use temperature for a long time - foam of polyurethane of PU of 　 of 　 of picture of 　 of ℃ of 240 ℃ ~80 bubble of horniness of board 　 polyurethane is mix with ester of different cyanic acid get together ether is main raw material, below the action of a variety of auxiliary such as foaming agent, activator, fire retardant, mix through special device, spot of spray of classics high pressure is epispastic and become high polymer polymer. Polyurethane bubble has soft bubble and hard bubble two kinds. Soft bubble is structure of starting a hole, hard bubble is closed pore structure; Soft bubble is divided again do not written guarantee to written guarantee the skin is mixed skin two kinds. Structure of sandwich of characteristic of board 　 product and high-tech of ◆ of 　 of 　 of representative application, high temperature applies PET bubble chemical function — is fought exceedingly goodly to fight solution, hydrocarbon, weak acid to wait for 　 　 ◆ below room temperature of 　 　 ◆ good mechanical performance- - high shear strength and high pressure shrink Neikenai gets short time of ◆ of intensity 　 　 the colophony solidify that is as high as 180 ℃ gives off heat ◆ of temperature 　 　 can reclaim the smoke poison with extremely low ◆ of recycle 　 　 discharges the FST with 　 　 exceedingly good ◆ (fire prevention, prevent, use as material of core of high-powered composite material, can simplify craft, shorten flow, case sucks the aperture that solves place of beehive core material to be faced with thickly, easily to take off stuck problem wetly, easily, solve material of general foam core the issue with lower than intensity, lower than modular quantity, small hear resistance. Advantage of PMI foamy performance depends on: Gao Li learns function: Have measure high than comparing a pattern intensity, high, its drawing, compress, bend, cut wait for each intensity and modular quantity all the other bubble such as far excel PVC, PU, PET or light Muxin material, and isotropy, can increase strength, improve tigidity, reduce weight. Felt of strong core of 　 of strong core felt is one kind basically is comprised by polyester fiber or fibre glass and atomic spherule, and by a kind but dissolve sticks the felt shape thing that receives one whole at the adhesive of styrene. The stiffness that uses strong core felt to be able to improve product apparently and can prevent wove to imprint piece, having irreplaceable effect to improving the quality of mould and product. Accordingly, strong core felt applies in the production of moulds of all sorts of glass reinforced plastics widely. Strong core felt serves as a kind of light simple stuff, already applied at establishment of component of shipping, car, You Le, wholesome clean to provide widely etc. 　 of beehive of paper of fragrant black silk ribbon is high temperature resistant, because this can be below the temperature of 200 ℃ above,have autoclave take shape; Density range is wide, from stere of 29-160 kilogram ／ , can satisfy different size structure requirement; Have extremely high shear strength, compare with photograph of bubble core material especially, suit to be used in light simple structure more; Tall tenacity, compare with photograph of material of core of other a honeycomb-like thing, the performance that fight caustic is high; Flame retardant, low smoke, low noxiousness (accord with aviation strict flame retardant with smoke poisonous standard) ; Exceedingly good creep and fatigue function, can asking Yan Ke's application is medium use for a long time; Extremely high wet intensity, can use in high humidity environment; Machine easily, reduce manufacturing cost; Anti-corrosive (won't be divided by water or other the medium place that contacts with its is corroded, also won't remove electrochemistry to react with carbolic fine envelope in that way like metallic beehive) ; Sex of conspicuous adiabatic sound insulation, relative to at metal and fibre glass material character, there are better heat insolation and sound insulation property below identical weight, more comfortable with energy-saving environmental protection; Easy processing, compare with metallic beehive photograph, beehive of fragrant black silk ribbon can bend, treatment is more convenient, the operation is more convenient. PP beehive board 　 is qualitative light: PP (polypropylene) the 1/12 that plastic beehive is quality of the seeper that be the same as body about, it is the 1/32 of aluminous material, can reduce the negative charge of the building greatly, the weight of traffic of car, boat, light rail. Sound insulation heat insolation: As a result of two air layer is divided into by beehive between board face numerous close interstitial, and PP (polypropylene) plastic, make sound and caloric transmission get very big limitation, because this is plastic,beehive board has good sound insulation heat proof quality. Intensity stiffness is big: Of unit quality bigger than intensity, bigger than stiffness. Convenient: Use installation is convenient, with general art design knife but aleatoric cut, make template of of all kinds different. Be able to bear or endure water, be able to bear or endure wet: Although also won't have in water,be out of shape wait for a circumstance. Avirulent and environmental protection, harmless: Be be machined by the PP that can use production Cheng Fang or things of the food that pack and become, reason is avirulent and harmless, won't send out any harmful gas, and can reclaim recycle. Anti-corrosive: Having good chemical stability is one of advantages of PP. Be isolated from: Having good insulating property and minor interpose report rate. Accomplish fire prevention: With proper face plate (be like fire prevention board) union, can accomplish fire prevention.
