Abstract
The utility model relates to an insulating pipeline shell for the glass fibre reinforced plastic protective pipeline. A glass fibre reinforced plastic protecting layer which is connected into integration with an insulating material is arranged outside the insulating material pipeline shell. The utility model has the characteristics of favorable waterproof performance, high insulating efficiency, good fire resistance, heat resistance, corrosion resistance, flame resistance, vivid color, complete color codes, etc. The utility model accords with the standard of the Ministry of Chemical Industry HGJ1074-79 ' The Regulations of the Heat Insulating Paint of the Chemical Equipment Pipelines ', and the utility model is convenient to construct and install.
Description
The invention belongs to chemical industry equipment, particularly the thermal-insulating pipe case of chemical pipeline.
Existing pipe insulation all is a shell of thermal insulating material being made in advance insulation, adds on shell during construction and wraps up in glass fiber cloth.This technology does not reach the requirement of waterproof, so its thermal insulation property also greatly reduces, in order to reach the requirement of waterproof, what have at present increases frp protective coverboard on shell, but it can not solve the seepy question at joint between the protection shell and pipeline valve, flange place.Metallized film or malthoid, plastic pellicle etc. are wrapped up in adding at shell of having, but can not solve seepy question preferably, because the material color of this parcel is fixed, can not reach the regulation of tinting about pipeline among the standard GHJ1074-79 of the Ministry of Chemical Industry " the insulation paint rules of chemical industry equipment pipeline " on the other hand.
The purpose of this invention is to provide a kind of have good water-proof performance, insulating efficiency height and good weather-proof, heat-resisting, anti-corrosion, flame retarding.Have simultaneously bright-colored, color code is complete, beautify the environment, civilized equipment, the glass fibre reinforced plastics protection pipeline thermal-insulating pipe case of construction install convenience.
To achieve the above object, the present invention adopts the appearance at thermal-insulating pipe case to add to wrap up in glass fiber cloth, and the brushing resin, then can be made into the integral body that the thermal-insulating pipe case of glass fibre reinforced plastics protection is arranged after the curing.At the scene in the construction to each joint, seam, flange, the brushing normal temperature cure of valve place fiber glass resin with color, then can form a civilization, attractive in appearance, a complete waterproof thermal-insulated pipeline that performance is up to standard.
Specifically, with thermal insulating material, one or more mixing admixture Bonds wherein such as alumina silicate, mineral wool, rock wool, perlite, glass wool foamed glass, expandable plastic are made the thermal insulating material shell.Add again at the outer surface of shell and to wrap up in glass fiber cloth and to be added on fixing, one end of its glass fibre is concordant with the thermal insulating material shell, the other end grows the length of a joint distance than thermal insulating material, brushing resin more later on, used resin is unsaturated resin, phenolic resin, polyurethane resin, alkyd resin, polyester, epoxy resin, acrylic resin, with PVC, polystyrene, chlorinated polyvinyl chloride etc., and their hybrid resin.Because be to do bed course during the brushing resin with thermal insulating material, infilter the part resin in the thermal insulating material, play the cementation of thermal insulating material and resin, thermal insulating material energy and glass fibre reinforced plastics protective coating are connected as a single entity.
In fiber glass resin, can add various auxiliary agents and material modified and versicolor pigment such as light stabilizer, heat stabilizer, X ray absorbing agent, fire retardant, antifungus according to product purpose, penetrate type, flame retardant type, mould-proof-type and acidproof, alkaline-resisting, soft, medium-soft matter and colors such as bright red, orange, dark blue, light blue, yellow, green, light green, white, black are arranged thereby produce weather resistant, heat resistant type, the X-ray-preventing width of cloth.For adapting to the requirement difference of various pipelines, form the glass fibre reinforced plastics protection pipeline thermal-insulating pipe case of the ordinary construction formula of can producing respectively, anti-rust structure formula, catoptric arrangement formula, reflection anti-rust structure formula etc. from external structure simultaneously to thermal insulation property and rustless property.
Further specify with reference to the accompanying drawings:
With reference to Fig. 1, be the sectional view of the glass fibre reinforced plastics protection pipeline thermal-insulating pipe case of a kind of ordinary construction formula of the present invention, be used for general pipe insulation.1 is the glass fibre reinforced plastics protective coating among the figure; The 2nd, adiabator layer, this ordinary construction formula is certainly made various flame retardant types, heat resistant type etc. and shades of colour.
With reference to Fig. 2, it is a kind of sectional view of the present invention with glass fibre reinforced plastics protection pipeline thermal-insulating pipe case of steel pipe anti-rust structure formula, because corrosion takes place in the surface of contact of steel pipe and thermal insulating material easily, and corrosion degree is difficult for finding, often invar pipe rust is worn and leakage accident is taken place, the present invention adds an amount of antitarnishing agent at the internal layer of making thermal-insulating pipe case, makes steel pipe anti-rust structure formula.1 is the glass fibre reinforced plastics protective coating among the figure, the 2nd, and adiabator layer, the 3rd, resist layer.
With reference to Fig. 3, be the sectional view that a kind of glass fibre reinforced plastics with catoptric arrangement formula of higher heat insulating ability of the present invention protects thermal-insulating pipe case, 1 is the glass fibre reinforced plastics protective coating among the figure; The 2nd, adiabator layer, the 4th, reflecting layer.The material in this reflecting layer adopts metallized film, or is coated with the terylene or the plastic sheet of other metals, or thin matter tinsel etc.This reflecting layer can reflect back a part of heat of unofficial biography again, because thermal insulating material is from reduction transmission of heat and thermoconvection insulation effect, and the heat radiation loss can be reduced in the reflecting layer, thereby further improves the thermal insulation property of pipeline.
With reference to Fig. 4, be the sectional view of a kind of glass fibre reinforced plastics protection pipeline thermal-insulating pipe case that reflects the anti-rust structure formula of the present invention, it is antirust and need steel pipeline than high heat preservation performance simultaneously to be used for needs.1 is the glass fibre reinforced plastics protective coating among the figure; The 2nd, adiabator layer; The 3rd, resist layer; The 4th, the reflecting layer.
Narrate embodiment below:
Its technology of glass fibre reinforced plastics protection thermal-insulating pipe case of producing the ordinary construction formula of φ 55 * 160 * 800 is: the plug of 1, loading onto φ 55 on forming machine; 2, to be inserted in the template of φ 160 and to adjust distance be 800 at two; 3, start the mineral wool that forming machine and interpolation are mixed with Bond; 4, be of the required size after, shut down, discharging; 5, oven dry; 6, thermal-insulating pipe case is inserted in the machine of pasting; 7, load onto the body flange of φ 160 * 50; 8, start the machine of pasting, superscribe two layers of glass fiber cloth, 9, draw together the brush fiber glass resin; 10, discharging; 11, solidify; 12, shed body flange; 13, check, warehouse-in.
