摘要： A laser-sinterable powder product has been prepared having unique properties which allow the powder to be sintered in a selective laser sintering machine to form a sintered part which is near-fully dense. For most purposes, the sintered part is indistinguishable from another part having the same dimensions made by isotropically molding the powder. In addition to being freely flowable at a temperature near its softening temperature, a useful powder is disclosed that has a two-tier distribution in which substantially no primary particles have an average diameter greater than 180 .mu.m, provided further that the number average ratio of particles smaller than 53 .mu.m is greater than 80%, the remaining larger particles being in the size range from 53 .mu.m to 180 .mu.m. A powder with slow recrystallization rates, as evidenced by non-overlapping endothermic and exothermic peaks in their differential scanning calorimetry characteristics for scan rates of on the order of 10.degree. C. to 20.degree. C. per minute, will also result in sintered parts that are near-fully dense, with minimal dimensional distortion.

摘要： A composite powder specially adapted for use in selective laser sintering is disclosed. The composite powder includes a polymer powder dry mixed with a reinforcement powder, where the polymer powder has a melting temperature substantially lower than that of the reinforcement powder. In the case where nearfully dense parts are to be formed, the first constituent powder is preferably a semi-crystalline powder, for example nylon 11, of a composition suitable for forming near-fully dense parts when used unblended in selective laser sintering; if porous parts are desired, the polymer powder is an amorphous powder, such as polycarbonate, polystyrene, acrylates, and styrene/acrylate copolymers. The reinforcement powder is preferably microspheres of glass, preferably coated to enhance wetting and adhesion with the polymer powder when selective laser sintering is performed. Besides improving the stiffness and heat resistance of the part produced, the composite powder widens the process window over that provided by unblended powder, provides improved dimensional accuracy in the part produced, and facilitates roughbreakout and smooth finishing of the part produced.
摘要翻译：公开了一种特别适用于选择性激光烧结的复合粉末。复合粉末包括与增强粉末混合的聚合物粉末，其中聚合物粉末的熔融温度基本上低于加强粉末的熔融温度。在要形成接近密集部分的情况下，第一组分粉末优选为半结晶粉末，例如尼龙11，适合于在选择性激光烧结中未掺杂时形成近乎致密部分的组合物; 如果需要多孔部分，聚合物粉末是无定形粉末，例如聚碳酸酯，聚苯乙烯，丙烯酸酯和苯乙烯/丙烯酸酯共聚物。增强粉末优选是玻璃微球体，优选涂覆以在选择性激光烧结时增强与聚合物粉末的润湿性和粘合性。除了提高所生产部件的刚度和耐热性之外，复合材料粉末使工艺窗口比非混合粉末提高了加工窗口的尺寸，提高了产品尺寸精度，并促进了生产部件的破裂和光滑整理。

When the powder is a semicrystalline synthetic resin having a number average molecular weight in the range from about 30,000 to 500,000; a molecular weight distribution M.sub.w /M.sub.n in the range from 1 to 5; and, provides a window of sinterability in the temperature range from near the powder's softening temperature T.sub.s to its caking temperature T.sub.c, it is sintered layer-upon layer to form a near-fully dense part of arbitrary shape.

摘要： Vinyl chloride (VC) resins, particularly poly(vinyl chloride) (PVC) and chlorinated poly(vinyl chloride) (CPVC) are reinforced with glass fibers which have been sized with a particular aminosilane coupling agent and a particularly characterized basic film former. At the processing temperature of VC resin, containing a stabilizer against degradation during thermoforming, for example in an extruder, or on a mixing mill used to blend the resin with sized glass fibers, a reaction occurs between an aminosilane coupling agent and the VC resin which reaction involves C.dbd.C bonds in the homopolymer, provided the polymer film former in the size is more basic than poly(vinyl acetate) ("PVA"). The film former catalyzes the thermal dehydrohalogenation of the VC homopolymer at the fiber-resin interface so as to generate allylic Cl moieties in chains of the homopolymer, which moieties react with the amine groups of the aminosilane. The size is most conveniently coated on the fibers from a sizing solution, dispersion or emulsion containing the coupling agent and film former in which allylic Cl moieties in VC resin chains become covalently bonded to an aminosilane, so that even upon thorough extraction of a GFR VC composite with tetrahydrofuran (THF), sufficient bound VC resin remains so that X-ray photoelectron spectroscopic (XPS) examination indicates that the ratio of total chlorine to total carbon remaining on the surface of the glass fibers, i.e. the ratio of the areas of the "Cl(2p)/C(1s)" peaks, is at least 0.91.

摘要： Oxidation of chlorinated hydrocarbons ("CHC") is effected in a fluidized bed of alumina catalyst-support on which is deposited a "soft" metal as the active catalytic ingredient, and the bed is fluidized with a nitrogen-free oxygen-containing stream of HCl gas, in conjunction with steam. The steam, in a particular range of proportions relative to the HCl, stifles the production of free Cl without blinding the active catalyst sites so that conversion of the CHCs is always at least 95%. The process comprises contacting the CHCs in the vapor phase with a fluidized bed of a catalyst-support on which is deposited an effective amount of iron, or copper, or both, in an active form, sufficient to convert in excess of 95% of the CHC on a molar basis, and the bed is fluidized with HCl, superheated steam and oxygen substantially free of nitrogen.In a particular embodiment using a single ("catoxid") reactor, the effluent is purged of water, unconverted CHCs, CO.sub.2 and some HCl, and the remaining predominantly HCl stream is recycled to the catoxid reactor. In another embodiment of the invention, the effluent from the catoxid reactor is fed to a second ("oxy") reactor to recover the HCl values by reaction with ethylene, air and HCl to produce 1,2-dichloroethane; the effluent from the catoxid reactor helps to fluidize the catalyst in the oxy reactor.
摘要翻译：氯化烃（“CHC”）的氧化在氧化铝催化剂载体的流化床中进行，其上沉积有“软”金属作为活性催化成分，并且用无氮氧含量的流 HCl气体，与蒸汽结合。在相对于HCl的特定比例范围内的蒸汽抑制游离Cl的产生，而不会使活性催化剂位点发生盲目，使得CHC的转化率总是至少为95％。该方法包括使气相中的CHC与催化剂载体的流化床接触，其上沉积有效量的活性形式的铁或铜或两者，足以转化超过95％的 CHC以摩尔为基准，床用HCl流化，过热蒸汽和基本上不含氮的氧气。在使用单个（“催化氧化”）反应器的特定实施方案中，流出物被清除水，未转化的CHC，CO 2和一些HCl，并且剩余的主要是HCl流被再循环到催化反应器中。在本发明的另一个实施方案中，将来自催化氧化反应器的流出物进料至第二（“氧”）反应器以通过与乙烯，空气和HCl反应产生1,2-二氯乙烷来回收HCl值; 来自催化氧化反应器的流出物有助于使氧反应器中的催化剂流化。

摘要： This method teaches how to recover and reuse a powder of a thermally degradable material which is used in a selective laser sintering (SLS) process. To recycle such a laser-sinterable powder successfully in a SLS machine it is protected against degradation by cooling the hot bed while layer-upon-layer (layer-wise) of powder is being sintered, seriatim, to form successive slices fused together to form an article of arbitrary shape (part). The process requires maintaining the powder which has more than 80% of the number of particles

摘要： At least three, and as many as eighteen, most preferably at least nine, crosslinking sites are provided through the alkoxy groups in multiple chains on a triazine ring (hence "multisilane"), on a single molecule of the multisilane. The multisilane, useful as a coupling agent, is formed by reacting a triazine-containing compound with a suitable aminoalkyl-alkoxysilane, or, alkyl-aminoalkyl-alkoxysilane in either an anhydrous, or an aqueous liquid medium. A size containing the multisilane, enhances the reinforced properties of organic synthetic resinous materials in which the fibers are used, and most particularly those of rigid poly(vinyl chloride) (PVC) with which it provides cohesive bonding of glass fiber surfaces. Glass fibers coated with a basic film former and the multisilane are covalently bonded on the one hand through some of at least nine alkoxy groups on each of the multisilane molecules, to Si atoms of a glass surface, and on the other hand, through at least some of the amine groups on each of the molecules, to the vinyl chloride (VC) resin in a reaction which involves allylic chloride bonds in the VC resin. The multisilane is effective in adhesives for a wide variety of materials, and in protective coatings.
