Description

Powder sintered type ball bubble triangular facet frame material

Field: new material

Background: the physical property of moulding material is one of key of its purposes of decision, and the physical property of section bar mainly is by the molecule arranging structure of the material that constitutes section bar and the decision of intermolecular affinity.Generally speaking, physical change such as distortion of materials, fracture mainly is that variation has taken place for the local molecules align of material substance.The proportion of object is that the external volume by the proportion of the material that constitutes object and object is determined that the proportion of the hollow object necessarily solid body proportion than identical material and volume is little.After many materials are made the hollow ball of certain thickness (shell thickness), fill confined gas with suitable pressure, under certain condition, this inflation hollow ball can with applied load be not less than the medicine ball of identical material, equal volume, because when airtight inflatable ball is subjected to the external force of certain orientation, gas can evenly be transferred to this external force all directions beyond the stress point in the ball simultaneously in the ball, and all directions all have spherical shell, have just become the stressed whole world, a place to bear.Medicine ball is just relatively poor relatively in this respect.If such hollow ball (here we are the ball bubble) that fills with the gas of suitable pressure is regarded as a material molecule, artificially these " molecules " are arranged by the most firm (diamond molecule arranging structure) triangle body structure (referring to accompanying drawing 1), and make this stable array, be combined into material with certain profile, when so this material is subjected to external force in the part, power can be disperseed (referring to accompanying drawing 2) in material internal transmits, avoided the concentrated destructiveness of power to material.We claim that this material is the ball foam material.

Moulding material and mechanical component etc. (the chemical reaction consume material that does not comprise moulding) mainly determine the section bar and the member of purposes with physical property, in the chemical property index when adapting to working environment, the chemical property of section bar and component surface is topmost index.The people has full surface for making, and inside is section bar or member (main application is determined by its physical property) the main chemical property index of its integral body and solid profile or the member and the no significant difference of identical material of empty spherical Triangle Network Structure (just the space of ball bubble triangle arrangement connects) (referring to accompanying drawing 3).Simultaneously the structure of this section bar or member (here we are the face frame) also is a kind of grid structure of tool fastness, if raw material itself possesses very high strength or the high-strength muscle net of adding then be the most firm a kind of rack (we claim that this structure is the triangular facet shelf structure) in its structure.

The raw material that meets instructions for use with chemical property is the face frame, guarantees the condition that conforms of section bar or member

Performance and whole fastness; With the physical property and the less proportion of ball bubble triangle material section bar or member, their organic combination is exactly ball bubble triangle, face frame composite.

Purpose: preparation adapts to various complicated environmental conditions and high-strength light section bar or member.

Scheme: one, the ball infusion is equipped with

1, the preparation of ball cell-shell.The ball cell-shell is exactly a hollow ball shell, and the material that has fixed stability, certain intensity and toughness in principle after all plastic types, the moulding all can be used as the raw material of making the ball cell-shell.According to the raw material difference, adopt corresponding method, it is well-balanced, inflatable airtight to be made into quality, and airtight back is with the open circles team body of certain pressure (internal inflation pressure and external bearer pressure, specific requirement requires to decide according to section bar or member finished product).Ball cell-shell body thickness, diameter are according to selecting for use raw material, section bar or the requirement of member finished product to decide.Ball cell-shell quality, the specification identical (also can decide as requested) that are used for same finished product.Generally speaking, once the ball cell-shell is established an air-filled pore.Can establish automatic Odour seal device in the air-filled pore, also can not establish (deciding according to inflation method), special circumstances can not established air-filled pore when external pressure equates in the ball bubble (require under the normal temperature).

2, ball bubble inflation.Inflation method generally can be selected for use high-pressure aerated (being provided with the Odour seal device in the ball cell-shell air-filled pore) or low-temperature liquefaction inflation (with injecting in the ball cell-shell behind the low-temperature gas liquefaction) reaches sealing air-filled pore after the requirement aeration quantity, require behind the sealing air-filled pore outer do not have obviously concavo-convex.Generally fill in the ball bubble with air or nitrogen (preventing the oxidation internally of ball cell-shell body) also can charge into other not with the gas of ball cell-shell body generation chemical reaction, air pressure is definite according to section bar or the requirement of member finished product, and special circumstances can not inflate (the interior external pressure of ball bubble is equal on the finished product requirement normal temperature) even ball steeps interior gas pressure less than atmospheric pressure (the interior pressure of ball bubble raises automatically under the high temperature).With bearing load or extruding check, the ball bubble does not have gas leakage, housing flawless and flat shell phenomenon at last.

Two, muscle net preparation

1, raw material is selected.Preparation muscle net is generally selected alloy-steel wire (bar) for use, also can select for use carbon fiber, Kev high-strength material such as to draw, the affinity of the face frame material that requires and select for use strong (can be integral with face frame material secure bond), concrete specification and quality require to decide according to section bar or member finished product.A muscle net can be selected the muscle silk or the bar of one or more specifications for use, the muscle silk or the bar of the identical quality of the right to use in general same the throwing the net, also can select for use differing texture but must can weld each other.

2, the muscle net is made.Muscle silk or the bar chosen are weaved into and section bar or the identical double check with a core of member finished product profile

(referring to accompanying drawing 4) hollow cage net.Each space of wire side all can be independent triangle.The tensile strength of the infall solder joint of muscle silk or bar should be at identical muscle silk of wall scroll or more than five times of bar.The specification of muscle silk or bar and density require to decide according to section bar or member finished product in the muscle net.According to circumstances also can make local muscle net (only in some face frame of section bar or member finished product, using) or not make the muscle net.

Three, ball bubble, muscle net surface scale removal (rust)

1, surperficial scale removal (rust).For the strong bonded of ball bubble, muscle net and face frame material, the spot and the oxide layer of ball bubble muscle net surface need make an overall screening.According to circumstances can select chemical cleaning or apparatus frictional cleaning for use, but also the two combination.After cleaning, spread removing surface agent (such as welding agent water) and adhesive in case of necessity.According to circumstances can arrange earlier and afterwards clean or clean afterwards earlier and arrange.

Four, the ball bubble is arranged

(ball bubble triangular facet frame material section bar or member generally all make up in mould and finish earlier the muscle net of making to be placed the finished product mould, mould is the forming method selected for use according to the kind of section bar or member finished product profile and face frame raw material and according to raw material variety and special particular manufacturing craft) in, the local muscle net that to make when using local muscle net is placed on the relevant position in the mould, certified ball bubble is pressed triangle body (referring to accompanying drawing 1,2,3) structural arrangement and directly is not arranged in the mould when not using the muscle net in the muscle net.

Should spread one deck powder when arranging the ball bubble, arrangement one deck ball steeps, and guarantees that each slit between the ball bubble all is covered with powder, and the ball bubble is arranged requirement neatly, closely, and the center of circle virtual line connection of arranging each ball bubble after finishing can be positive triangle body (referring to accompanying drawing 5).

Five, synthetic: the mould that will arrange the good shot bubble is gone into kiln, reach sintering temperature after the warm certain hour of weighing apparatus (guaranteeing to be heated evenly, all sintering) kiln discharge remove mould after cooling off, be finished product.
