Description
The present invention relates to the resist technology of metal products, the protecting materials that the present invention uses is extensive, comprises various plastics, natural and synthetic rubber, the resin of various performances and cement.Spraying paint of using at present waits resist technology, all exists protective layer to come off easily and shortcoming that guard time is lacked.Use the present invention can overcome above-mentioned shortcoming, the protection period of wall of metallic product was more than more than ten 20 years, and metal products can be used in the strong acid-base environment, plastics, resin, rubber, cement etc. are applied in pressure-vessel.At present, at the fastening mesh screen of wall of metallic product () (two), topped again protecting materials (three), the technology that metal products is protected for a long time is not reported.
The present invention not only exhibits one's skill to the full in chemical industry, and also has place to show one's prowess in shipping interest, uses protecting materials, as protection shells such as plastics following advantage is arranged: 1. shell does not reach water and can not get rusty, and makes the usage period of ship prolong.2. in protecting materials, add corresponding medicament, can kill the shellfish that will grow nonparasitically upon another plant at shell.3. in protecting materials, add hydrophober, can reduce the friction of shell and water, increase the speed of a ship or plane.4. the shell non-corrosive does not have shellfish to grow nonparasitically upon another plant again, can reduce and go up depressed place servicing time.
Mesh screen is fastening on the wall of metallic product, comprises that welding, nut (five) are tightened with little hook (six) to catch on three kinds.Division is as follows: the first, and spot welding wire-mesh screen on wall of metallic product makes and leaves little space between mesh screen and the wall of metallic product.The second, weldering many screws (four) on wall of metallic product, (five) are tightened in mesh screen on the screw with nut.The 3rd, weldering many little hooks (six) catch on mesh screen with little hook on wall of metallic product.
The mesh screen that wall of metallic product tightens has two kinds of wire-mesh screen and nonmetal mesh screens.
Common people know, and when several objects have constituted one, just have good stability.For example two active wooden units are pegged by iron nail and are become one, and the stability between wooden unit is just very strong, are not easy separately.This principle of the present invention utilization is carried out, the resist technology that relies on intermolecular gravitation to be close together, and stability is not strong, for example sprays paint etc., under the reactive force repeatedly of cold shrinkage and thermal expansion, protective layer will take place break away from and lose provide protection.The present invention is by electric welding, and molten remittance of wire-mesh screen and wall of metallic product is combined into one, and stability is extremely strong.Make simultaneously protecting materials parcel mesh screen again, make protecting materials pass through mesh screen and wall of metallic product is set up extremely strong stability.When the effect of cold shrinkage and thermal expansion made protecting materials break away from wall of metallic product, wall of metallic product was just tightly held the protecting materials layer by wire-mesh screen.Because this pulling force is more much bigger than the reactive force of cold shrinkage and thermal expansion, thereby protective layer can not break away from wall of metallic product, and the things such as soda acid, steam that make attack metal goods wall can't enter and protect wall of metallic product.And for example screw is welded in wall of metallic product; the molten remittance of screw and wall of metallic product is in the same place; with nut mesh screen is tightened on the screw again; when making protecting materials then with screw, nut and mesh screen parcel; fill up screw thread, make nut and mesh screen permanent set on a position and demonstrate very strong stability.For another example, little hook is welded in wall of metallic product, also molten remittance of little hook and wall of metallic product is in the same place, and also space between little hook and the mesh screen can be filled up during protecting materials parcel mesh screen, makes the mesh screen permanent set on a position and show very strong stability.So they all can reach same protection effect.
Because the protecting materials that the present invention uses, its chemical stability is fine, and for example plastics are not decomposed and strong acid-base resistance by bacterium, and and for example cement stabilizing had more than 50 years, so guard time can reach more than more than ten 20 years.
Have on mesh screen that heating is topped, normal temperature is topped and it is topped to dissolve with protecting materials is topped, heat topped first topped and back topped two kinds of the protecting materials that divides again.
Topped protecting materials is earlier now described; Jia Re method then: lay protecting materials plate on wall of metallic product fastening mesh screen; for example plastic plate, resin plate, rubber plate; with heating unit the protecting materials plate is heated then; the heat energy that its absorption heating unit is discharged becomes the melten gel shape; again with pressurizing device calendering, make it be close to mesh screen on wall of metallic product and the coated metal goods wall.In the process that pressurizing device from one end to the other side rolls; the gas that melten gel shape protecting materials will be stayed between melten gel shape protecting materials and the wall of metallic product is driven away; being close to wall of metallic product then stretches; after passing the little space between mesh screen and the wall of metallic product mesh screen is wrapped up, and be pressed into firmly level and smooth again protective layer.
Introduce first heated protective material again; topped then method: with heating unit with protecting materials; for example plastics, resin, rubber are heated into the melten gel shape; be laid in then on the mesh screen of wall of metallic product; roll with pressurizing device; make its mesh screen of being close to wall of metallic product and coated metal goods wall, become level and smooth firm again protective layer.
The second, introduce the topped method of normal temperature: protecting materials cement adds entry, sand, stone; perhaps cement adds entry, sand, asbestos or aluminum silicate fiber; mix the paste shape through doing; replace above-mentioned melten gel shape protecting materials; undertaken by topped method after the heating earlier, wall of metallic product also can obtain good equally protection effect.
Three, say the topped method of dissolving at last: with protecting materials, for example plastics, resin, rubber organic solvent dissolution spray or are coated on wall of metallic product and the wall of metallic product fastening mesh screen, perhaps metal products are immersed in the dissolved protecting materials.Spray be coated with or the process of soaking in, the dissolved protecting materials is driven the gas that is attached on wall of metallic product and the wall of metallic product fastening mesh screen away, and attached to it.The drying of bleeding when the protecting materials layer loses flowability repeats repeatedly to reach requirement until topped thickness, and apply every square centimeter 0.1 kilogram (0.1kg/Cm to the protecting materials layer this moment
2) above air pressure, the drying of bleeding is changeed in slowly step-down after about 10 minutes, repeats repeatedly to reach requirement until drying, do not want unexpected step-down during step-down, otherwise protective layer will break away from wall of metallic product and lose provide protection.Apply air pressure at the protective layer the later stage of drying; issuable size bubble in the time of not only can eliminating organic solvent evaporation; make protective layer tightr, and make protective layer be close to wall of metallic product and wall of metallic product fastening mesh screen more, make protective layer that the better protection effect is arranged.Simultaneously, use and bleed and compression set, not only can reclaim organic solvent and also can shorten time of drying.
The present invention preferentially uses the protecting materials plate in the heating sheathing method, for example plastic plate etc. is greatly simplified complete processing, and its only needs just can protect metal products with simple machinery, and the workyard is unrestricted.For example, it is simply to only need just protecting shell on the water surface with a thermal chimney and a hand propelled cylinder.
