Description
Technical field
The utility model relates to a kind of load type glass-fiber reinforced plastic grille sheet material.
Background technology
Flase floor carries out cross arrangement with band steel according to certain spacing and cross bar, by press welder or be manually welded into middle a kind of steel product with square grid, flase floor is mainly used to make ditch cover plate, steel structure platform plate, the step plate etc. of steel ladder, cross bar generally adopts the square steel through twisting.
Flase floor preparation method has machine pressure welding and makes two kinds by hand.
Machine pressure welding uses high-tension resistive press welder, cross bar is disposed across on evenly distributed band steel by manipulator automatically, by powerful electric welding power and hydraulic coupling, cross bar pressure welding is entered in band steel, thus it is firm to obtain solder joint, stability and the high high-quality steel grating of intensity.The impact that this welding procedure is mated by equipment and Current Voltage, the welding of general two bar is higher than the intensity of single pole, and this welding procedure also has relation with the height of raw material band steel, and band steel width error is large may affect weld strength, makes intensity inconsistent; The defect that this technique exists is dry joint and rosin joint, and dry joint and rosin joint easily make cross bar strip off.Welding procedure is because of the rated capacity of equipment equipment, and the larger heavy steel grating in cross section cannot be produced.The equipment rated capacity of this welding procedure lower than the band steel steel grating that generally can only do below 4mm thickness of 800KVA, the general band steel steel grating that can do 5 ~ 6mm thickness of 1250KVA.
Home built steel grating has pressure lock, welding, interlocking to exempt from weldering etc.The steel grating making welding by hand is elder generation's punching or notch on band steel, and then cross bar is put into hole spot welding, cross bar and band steel can exist space, and cross bar welds with each contact point of band steel, and what cross bar was close also can dot interlace weldering.This production technology relatively flexibly, product diversification, substantially can production complete series steel grating, heavy type has superiority; Because welding all artificial manual weldings, easy not prison welding is solid, solder skip, dry joint, produce dry joint and solder skip reduces intensity.
Fiberglass another name fiberglass reinforced plastics, is commonly called as FRP(Fiber Reinforced Plastics), i.e. fibre-reinforced plastics.Fiber difference according to adopting is divided into glass fiber reinforced composite plastics (GFRP), fibre reinforced composite plastic (CFRP), and boron fibre strengthens composite plastic etc.
It as reinforcing material, makes a kind of composite of matrix material using glass fibre and goods (glass cloth, band, felt, yarn etc.) thereof with synthetic resin.Fibre reinforced composites are made up of fortifying fibre and matrix.The diameter of fiber (or whisker) is very little, and generally below 10 μm, defect is less less again, and breaking strain is about within 30/1000ths, is fragile material, easy damaged, ruptures and is corroded.Matrix phase is for fiber, and intensity, modulus are all much lower, but can withstand large strain, often has viscoplasticity and elastoplasticity, is toughness material.
Because used resin variety is different, therefore there is the title of organic toughened glass, fiber glass epoxy, phenolic fiberglass reinforced plastics.Light weight and hard, non-conductive, mechanical strength is high, recycles few, corrosion-resistant.Steel manufacturing machine part and automobile, ship housing etc. can be replaced.
The advantage of fiberglass is: high-strength light.Relative density, between 1.5 ~ 2.0, only have 1/4 ~ 1/5 of carbon steel, but hot strength is close, even exceedes carbon steel, and specific strength can compared with high-grade alloy steel.Therefore, at aviation, rocket, space vehicle, high-pressure bottle and need to alleviate in the product application of deadweight at other, all there is remarkable effect.The stretching of some epoxy FRP, bending and compressive strength all can reach more than 400Mpa.Corrosion-resistant.FRP is good anticorrosive material, has good resistivity to the acid of air, water and general concentration, alkali, salt and multiple oils and solvent.Be applied to the various aspects of chemical anticorrosion, replace carbon steel, stainless steel, timber, non-ferrous metal etc.Good electrical property.Be excellent insulating materials, be used for manufacturing insulator.Still good dielectricity can be protected under high frequency.Microwave transparent is good, is widely used in radome.Hot property is good.FRP thermal conductivity is low, is 1.25 ~ 1.67kJ/(mhK under room temperature), only having 1/100 ~ 1/1000 of metal, is excellent heat-insulating material.In instantaneous superhigh temperature situation, be desirable thermal protection and ablation resistant material, space vehicle can be protected more than 2000 DEG C to bear washing away of high velocity air.Designability is good.(1) as required, various infrastructure product can be designed neatly, meet instructions for use, product can be made to have good globality.(2) fully can meet the performance of product by selection material, as: can corrosion resistant be designed, resistance to TRANSIENT HIGH TEMPERATURE, product direction has special high strength, dielectricity is good, etc.Manufacturability is excellent.(1) moulding process can be selected neatly according to the shape of product, technical requirement, purposes and quantity.(2) technique is simple, can one-shot forming, and economic effect is given prominence to, especially few to quantity that is complex-shaped, not easy-formation product, its technique superiority more outstanding.
The shortcoming of fiberglass is: elastic modelling quantity is low.The large twice of modular ratio timber of FRP, but less than steel (E=2.1E5) 10 times, in product structure, therefore often feel that rigidity is not enough, be easily out of shape.Shell structure, sandwich can be made, also by high modulus fibre or do the forms such as reinforcement to make up.Long-term temperature tolerance is poor.General FRP can not at high temperature Long-Time Service, and general purpose polyester FRP intensity more than 50 DEG C just obviously declines, general only use 100 DEG C below; Universal epoxy FRP is more than 60 DEG C, and intensity has obvious decline.But can fire resistant resin be selected, make Long-term service temperature be possible at 200 ~ 300 DEG C.Aging phenomenon.Aging phenomenon is the common defects of plastics, and FRP is no exception, under the effects such as ultraviolet, dust storm sleet, chemical mediator, mechanical stress, easily cause hydraulic performance decline.Shear strength is low.Interlaminar shear strength is born by resin, so very low.Can, by selecting technique, using the methods such as coupling agent to improve interlayer adhesion, most importantly when product design, avoid interlayer is cut as far as possible.The production method of fiberglass divides two large class, i.e. wet method contact-type and dry method extrusion formings substantially.As divided by process characteristic, there is hand pasting forming, laminated into type, RTM method, ironing, compression molding, Wrapping formed etc.Hand pasting forming comprises again hand and sticks with paste method, pressure bag method, gunite, wet paste low-pressure process and stick with paste method without mould hand.
