The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited only to this.
Embodiment:
Like Fig. 1, Fig. 2, shown in Figure 3, a kind of ceramic wear-resisting coating backplate comprises wear-resistant paint layer 2, is provided with skeleton structure in the said wear-resistant paint layer 2.Wear-resistant paint layer 2 is connected in equipment surface easy to wear for weld strength (420Mpa), and skeleton structure is that bar-mat reinforcement and hexsteel 5 are welded on equipment surface, and wear-resistant paint layer 2 forms the wear-resistant paint backplate after coating skeleton structures.Wear-resistant paint layer 2 coats the wear plate of skeleton structure forming device surface 25mm fully.Ceramic wear-resisting coating backplate is mainly used in to be protected the surface of equipment or pipeline.
Said skeleton structure comprises bar-mat reinforcement and hexsteel 5, and said bar-mat reinforcement and hexsteel 5 all are arranged on wear-resistant paint layer 2 inside.
Said bar-mat reinforcement comprises the some reinforcing bars that are arranged in parallel 1, is vertically installed with connector 4 between the said parallel reinforcing bar 1, and welding is fixing between said connector 4 and the parallel reinforcing bar 1.During the making, the temperature of job location must be controlled between 5 ℃ to 40 ℃, crosses when low like temperature, and material itself reaches construction area and then must heat to 5 ℃, up to wear-resistant paint smear finish till.But should avoid directly constructing under Exposure to Sunlight or the high wind situation, to prevent the dry and cracked rapidly of wear-resistant paint surface.The abrasionproof equipment surface that will carry out is cleaned out, and skeleton structure is exposed form the body that hardens.Material and impurity that the surface is loosening are removed fully.With worn out or good near worn out abrasionproof position inwall soldering.
Every interval 150mm transverse weld 6# reinforcing bar 1 on the workpiece face is welded to connect part 4 again between reinforcing bar 1 earlier, and the weld spacing during welded reinforcement 1 is from being 100mm, symmetrical two-sided welding, fusion length 5mm.Adopt J422 welding rod (postwelding slagging-off).Its solder joint tensile strength mean value is: 420Mpa compression strength mean value is: 550Mpa.
Said hexsteel 5 mainly is made up of several tortoise plastron unit 3, and the bottom of said tortoise plastron unit 3 is arranged in the same horizontal plane.The welding specification is on reinforcing bar 1: 1.5mm*15mm*50mm, material is: A4 steel hexsteel 5, hexsteel 5 adopts the two-sided welding of arc welding, two-sided welding in the hexsteel unit 3 of each contact reinforcing bar 1 or connector 4, fusion length 0.8mm.The employing model is: J422 welding rod, (postwelding slagging-off).Its solder joint tensile strength mean value: 320Mpa, compression strength mean value: 550Mpa.
In order to ensure the most strong tack, should adjust hexsteel 5 during installation as far as possible, make the distance between hexsteel 5 and the construction surface be enough to let wear-resistant paint layer 2 envelope hexsteel 5 fully.
Welding is fixing between said hexsteel 5 and the bar-mat reinforcement 1.Hexsteel 5 is fixed with the spot welding mode with reinforcing bar 1, in whole hexsteels unit 3 of bond pad locations for contact reinforcing bar 1 or connector 4.
The effect of hexsteel 5 is intended to make and has been coated with the wear-resistant paint spread and solidifies unlikely the coming off in back, especially when vertical surface or backplate face down.
Be provided with the hard, wear-resistant ceramic aggregate in the said wear-resistant paint layer 2.Wear-resistant paint is a kind of novel surface protective material of the advanced composite technology institute Development and Production of employing; It is matrix with the high molecular polymer; In mix hard, wear-resistant ceramic aggregate and toughened fiber; And with the two component substance of catalytic modification agent combination, have characteristics such as wear-resisting grain washes away, media-resistant corrosion.The bond of wear-resistant paint adopts special glue (this glue is according to different climate, different seasonal, the special Binder Materials of different temperature developments), is commonly called as glue condiment.And a lot of so-called wear-resistant paints are arranged in the market is water condiment, and water condiment is castable refractory series, and (annotate: operating mode is a hydraulicity physical bond at the product of water condiment below 800 ℃; Bond strength is low, compactness is low; Cost is low, and water condiment certainly will cause the shortcakeization that combines plate body, and wearability is low.What glue condiment took place is chemical reaction; Bond strength and compactness are high, form whole wear-resisting plate body behind the curing molding, and hardness and abrasion resistance all are superior to water condiment); Wear-resistant paint can be combined closely with equipment after solidifying, and forms firm whole abrasion-proof backing block at the equipment inwall.
After the ceramic coating of powdered poured into, add the glue stir about 10 minutes of 6%-7% in proportion.These 10 minutes is to add to begin after glue finishes to calculate.
When the construction large area region, be necessary to be divided into the zonule, be convenient to the workmen and construct, promote construction speed.
Divide three interfaces to stir and construction: the construction, mixing time of horizontal surface should use in 10 ~ 15 minutes, and promptly material has good flowability, and glue quantity also will be controlled at minimum standard, avoids secondary to add glue; The construction of vertical surface: require mixing time (depending on weather conditions) more than 20 minutes; If necessary; Add the extra glue of 0.25KG (210 milliliters of about half cups) by 100KG/ dry powder; Each extra glue that adds stirred one minute again, up to obtaining suitable viscosity (can form " wet bulb "); Crown surface construction: when ceramic mortar was used for position, the crown, the mixing time that increases by 3 minutes will help the top and smear to obtain the bigger ceramic mortar of viscosity.For guaranteeing the construction work quality, the workman must stand in as far as possible and be coated with the place of wiping one's face near the crown, also need bow in case of necessity, and being the workman who smears so just has enough strength to press down coating to the joint portion.
Wear-resistant paint is smeared compacting and outstanding hexsteel 5 surperficial 4mm, and combining closely of complete 6mm (reinforcing bar 1 diameter) space, hexsteel 5 height 15mm and the hexsteel 5 outer surface 4mm wear-resistant paints that will reach hexsteel 5 and equipment surface is complete.
The utility model can be quick installed at ceramic wear-resisting coating backplate the surface of equipment, conveniently changes fast, has improved efficient.
Take aforesaid way, just can realize the utility model preferably.
