Description

Nano-micro level super powder composite material compression-moulding methods and equipment
Technical field
The present invention relates to the material technology field, particularly nano-micro level super powder composite material compression-moulding methods also relates to the method device therefor simultaneously.
Background technology
Superfine powder plane and special-shaped molded articles with certain mechanical strength and geometric accuracy relate to numerous industrial application.The moulding process of these members and equipment have determined the quality and the productive rate of end article.The nano-pore heat insulating materials of development in recent years particularly, promptly utilize the nanosize metal oxide powder to add the opacifier and the inorganic fibers of an amount of inhibition infra-red radiation, through fully mix, promptly can be made into after the compression moulding thermal conductivity factor the thermal conductivity factor of whole operating temperature range internal ratio still air also will be low heat-insulating material.This material according to instructions for use, is configured as the goods of definite shape, certain intensity, can extensively be adapted to the energy-conservation requirement of different industrial circles.
In the prior art, the final molding of this heat-insulating material often adopts dual mode:
A kind of mode is to adopt the even mixed nano composite powder of hypotonicity scrim envelope stuffing, rely on when forcing to discharge air in the compression moulding process, powder body material interts and to penetrate into big envelope and big envelope produces in pressing process elongation strain is combined closely whole briquetting body and encapsulating material, formation has the integrated rigidity sheet material of sufficient mechanical strength, improves the mechanical strength and the surface abrasion performance of end article with this.But encapsulating material main employing at present is the glass fibre fabric, and its heatproof is generally less than 700 ℃, uses under higher temperature, and regular meeting causes breakage.In addition, the making of the complicated shape of having relatively high expectations for geometric accuracy, utilize this technology to be difficult to meet the demands, on the one hand, the covering of big envelope makes heat-insulating shield can not make complicated shapes such as different in nature member, and carries out routine and add trade union and cause the pulverizing of adiabatic core material and break away from big envelope, on the other hand, the big envelope that is in extended state provides certain rigid, so can not bend to any curve form, can't satisfy the insulation demand of pipeline etc.
Another kind of mode is directly nano composite material to be pressed into bulk or special-shaped product in mould; this goods; when serviceability temperature is higher than 700 ℃; the problem that does not have encapsulating material to damage; but in the mold pressing manufacture process; the effect of elastic rod because mutually combined between particle and the particle; when the mixture of compacting takes out from mould; resilience can take place in the particle that bonds together; be to have bigger elastic after effect after pressure discharges; usually can cause the distortion of shaping block; distortion; cause actual density not reach design density, also followed the reduction of mechanical strength and the uncertainty of yardstick, often forming process is followed be full of cracks; can delamination and cracked, very easily damage when serious.At present processing mode is to add inorganic or organic adhesive improves the autoadhesion characteristic and improves intensity and reduce elastic after effect, as use the low melting point bonding agent, the heat-insulating material particle is bonded together, but the mechanical bond between the particle will increase thermal conductivity factor, and finished product needs post processing, as heat sintering or long time aging etc., all can influence the efficient of batch process.United States Patent (USP) 4529532 discloses a kind of " producing the technology of adhesive-free mold pressing insulation " 1985 days 16, in heat-insulating material, add nitrogenous material, the react acid in the aqueous solution of this material, increase bond strength between the particle with this, evenly mix as adopting ammoniacal liquor and particulate material; United States Patent (USP) 6099749 discloses a kind of " compacting contains the method for gas phase metal oxide component " on August 8th, 2000, use steam and many microporous thermal insulation materials mixture fully to mix, increase the mechanical strength after the final molding and reduce elastic after effect with this.But when making heat-insulating material with commercial size, the even dispersion of ammoniacal liquor and steam and powdered rubber fully contact comparatively difficulty of meeting, drop that is difficult to disperse or steam condensation very likely can cause the degeneration of end article heat-insulating property.
Except the manufacturing difficulty that elastic after effect caused, the shaping of nanocomposite exists also after the compacting everywhere that density refractory influences the mechanical strength of shaping block to reach inhomogeneity problem.Main cause is that the air content of nanometer grade powder is higher, in pressing process, gas can be discharged by the path of resistance minimum, if runner is not smooth, central gas can flow and promote material and move to the edge to periphery, the extrudate density inequality that makes final compression moulding, density lower and peripheral density in middle part is higher, causes product strength lower and very easily cracked.Simultaneously, because even mixed material density generally is lower than 50g/L, the very easily floating contaminated environment of conventional filling process also needs the corresponding techniques means to solve, and the solution of these technical problems is not appeared in the newspapers in public information at present as yet.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming and provide a kind of can high-quality, finish the nano-micro level super powder composite material that possesses higher mechanical strength and geometric accuracy accurately, and the nano-micro level super powder composite material compression-moulding methods that do not pollute the environment of powder.
