The invention discloses a biological degreaser for degreasing pretreatment in metal processing industry and method for processing greasy dirt on metal surfaces, which integrates the two independent processes of grease removing and greasy dirt decomposing, the biological degreaser containing oil-degraded microorganisms can not only scale off greasy dirt from metal surfaces, but also decompose the greasy dirt simultaneously.

An engine crankshaft of automobile is prepared from cast iron material. It features that material intensifying process is applied on said cast iron material i.e. utilizing isothermal hardening heat treatment to process normal graphite cast iron to be austenit-bainite graphite cast iron and making cast-state blank bailing grade be 1-2 grade as well as making graphite ball diameter be above 6grade.

A kind of desulfitation transformation method to regenerate Pb with waste chloride accumulator, it contains a procedure to break waste chloride accumulator, the liquid and the solid in the Pb mud fluid after breaking will be separated, and wet lead slime can be gained. The wet lead slime will be put into a desulfurizer. And sodium carbonate will be also added as desulfurating agent, then they will be fully agitated, they will fully react. The liquid and solid will be separated after stewing, The sediment lead carbonate and liquid sodium sulfate can be gained, the later will be put into a reactor, and barium carbonate will also be put in, then they will be agitated, and reacted fully, they will be stew, and then the liquid and solid of them will be separated, the sediment barium sulfate and liquid sodium carbonate can be gained, and the later will be delivered into the desulfurizer to recycle as desulfurating agent. This patent translates the reaction between sodium sulfate and barium carbonate in the remained liquid, recycle the desulfurater sodium carbonate. It not only resolves the problem how to deal with the sodium sulfate in the desulfitation transformation technology, but also resolves the regeneration and the recycle of desulfurater sodium carbonate.

This is a complex arrangement technology of three dimensions recall and inject drawing and printing for ready-to-wear clothes. It contains following steps: To do the arrangement for the ready-to-wear clothes: To arrange of polymerization and skein for them. Be arranged them in three dimensions in finished form by thermo-compression or to spur paint paste on their surface. To cure them on fire to fix colors, then to arrange them in their dimensions and pack them.

The invention discloses a novel composite powder of rubber substituent FA for substituting rubber to produce a wound clutch facing, which aims to solve the problems of consumption of disposable resource of petroleum, complex process, high production cost, hidden danger of safety and environment, 'three hot' of products and the like in the conventional method of producing the wound clutch facing by using rubber. The novel composite powder of rubber substituent FA is prepared by mixing polysaccharide powder, a stabilizing material, a coloring agent and an isolation material in a blender mixer according to a certain ratio, dosing sequence and dosage for a certain period of time. The novel composite powder of rubber substituent FA for producing the wound clutch facing has the characteristics of energy conservation, consumption reduction, environmental protection, sustainable development and the like, and has obvious economic and social benefits.

The invention relates to a beneficiation method of veinlet disseminated low-grade porphyry type copper ore, belonging to the technical field of mineral metallurgy processing. The technical problem tobe solved by the invention is the difficulty of low copper ore grade and various copper minerals in mineral processing. A technology for introducing a copper and associated gold and silver mineral high-efficiency combined collector, adding lime and sodium sulfide for pulp blending in roughing process and introducing sodium silicate and sodium hexametaphosphate in the fine screening process is adopted. The problems that the recovery rate of useful minerals is low, the fine screening process is long and the concentrate grade is not high in beneficiation of the veinlet disseminated low-grade porphyry type copper ore are solved. The recovery of main metal copper and associated gold and silver is effectively increased, the quality of copper concentrate is improved, the stability of beneficiation is improved, the adverse effect of seasonal temperature difference on mineral beneficiation indexes is overcome, the circulating reuse of mineral beneficiation wastewater is realized, and the mineral beneficiation cost and energy consumption are reduced. The invention is used for beneficiation of copper sulfide ores in high-cold seasonal frozen areas.

The invention discloses a heat energy device for preparing superheated steam with waste heat steam, which effectively solves the problem that conventional heat sources for drying brown coal are uneconomic and have the hidden troubles of ignition and explosion. The device comprises a partition wall, a base, a heat exchange part, an upper independent smoke box, a lower independent smoke box and upper and lower integrated smoke boxes. Key points are that: the heat exchange part is provided with a low temperature heat exchange region, a medium temperature heat exchange region and a high temperature heat exchange region which are formed by a tube bundle heat medium exchanger respectively; tube cavities of the tube bundle heat medium exchangers at each heat exchange region are communicated withthe cavities of the upper independent smoke box, the lower independent smoke box and the upper and lower integrated smoke boxes respectively; staggered tube gaps between an upper tube plate and a lower tube plate of each tube bundle heat medium exchanger at the heat exchange part form a communicated cavity; the communicated cavity of the low temperature heat exchange region is connected with a waste heat steam conveying tube; and the communicated cavity of the high temperature heat exchange region is connected with a superheated steam supply tube. The device has the characteristics of rational structural design, stable performance, easy maintenance, low operating cost, energy conservation, consumption reduction, emission reduction and wide application range and can reduce the one-time investment when used for drying the brown coal.

The invention relates to a preparation method of diphenylamine or a ring-substituted derivative thereof. The method comprises the following steps: utilizing an alkali metal alkoxide as an alkaline reagent, and performing reaction on halogenobenzene or the ring-substituted derivative thereof and N-acylated aniline or the ring-substituted derivative thereof in the presence of a catalyst to prepare the diphenylamine or the ring-substituted derivative thereof and simultaneously produce a second product, namely carboxylic acid ester. The molar ratio of the halogenobenzene or the ring-substituted derivative thereof, the N-acylated aniline or the ring-substituted derivative thereof and the alkali metal alkoxide is generally selected at 1.0:(1.0-1.1):(1.1-1.3). The method is utilized for producing the diphenylamine or the ring-substituted derivative thereof, and the method has the advantages of simple production process, short reaction period, high utilization rate of equipment, low energy consumption and a small quantity of three wastes.
