Abstract
The utility model relates to a novel spiral heat-insulation air duct for a ship. The novel spiral heat-insulation air duct is formed by coaxially connecting an outer pipe, a middle heat-preservation pipe and an inner pipe in sequence from outside to inside in a sleeved mode, both the outer pipe and the inner pipe are made of metal plates, and the middle heat-preservation pipe is a modified phenolic resin foaming heat-preservation pipe. Expandable modified phenolic resin foaming heat-preservation material is adopted, has the low heat conductivity coefficient which is 0.025-0.040 W/m*K generally, is good in heat preservation performance and difficult to combust, achieves self-extinguishing, less smoke and flame penetration resistance, produces no dripping when catching fire, and is low in toxicity, harmless to humans, good in heat stability, and capable of being used for a long time at the temperature from 140 DEG C to 160 DEG C; corrosion resistance is high, and corrosion caused by inorganic acid, organic acid and organic solvents, except for strong base, can be resisted; the foaming heat-preservation material has a good closed pore structure, low water absorption and high vapor permeation resistance, is free of moisture condensation during cold insulation, and is matched with the inner pipe and the outer pipe to form an integrated structure, the overall size is stable, the change rate of the overall size is small, the change rate of the size is less than 1% within a using temperature range, the structural strength is high, and using safety and non-deformation are achieved.
Description
Technical field
The utility model relates to a kind of airduct, is that a kind of modern ships that is applicable to is built the adiabatic spiral duct that industry central air-conditioner ventilates specifically.
Background technique
Adiabatic spiral duct is as the requisite important component part of ventilating of central air-conditioner in Modern Shipbuilding industry, and its material and preparation process are along with the continuous progress of science and technology is also in continuous renewal.Traditional ventilation duct scene processes with galvanized steel plain sheet, with thermal-protective material insulations such as rock wool or super glass wools, in processing and installation process, all can produce harmful dust, harmful, heat insulation effect relative mistake, and increased hull weight.Adiabatic spiral duct Assembling for existing ventilating duct of central air conditioner, simple and fast during installation, technique are simple, saved the plenty of time, and outward appearance are succinctly smooth, has beautified cabin.Using rock wool as thermal insulating material, and rock wool moisture absorption is strong, is out of shape, thereby does not reach due heat insulation effect for insulation very easily absorbs water, and has the phenomenon of running cold-peace corrosion steel plate; Rock wool is by machinery or manually enrich in the middle of two-layer spiral duct, due to the fiber properties of rock wool, has determined that its density is inadequate, and long-time vibration is used and had condensation phenomenon; The Organizational Structure of rock wool has determined that its mechanical strength is inadequate, airduct intensity difference; The fireproof performance of rock wool can reach A level, but serious to harm because of it, exists carcinogenic problem, and Systems in Certain Developed Countries has carried out strict restriction to the use of rock wool, sucks for a long time rock wool dirt and can cause brochial mucosa inflammation and pulmonary emphysema, the symptoms such as contact dermatitis; When rock wool produces, consume energy huge, need carry out remelting, fibrosis to raw material, can produce a large amount of waste water, waste gas, and consume mass energy, belong to high energy consumption, high pollutive industries.
Summary of the invention
The deficiency that adopts rock wool to do to exist in thermal insulating material in order to solve tradition ventilation pipeline, the utility model provide a kind of simple in structure, preparation process is simple, structural strength is high, use the peculiar to vessel novel adiabatic spiral duct of safety.
The technical solution adopted in the utility model is: a kind of novel adiabatic spiral duct peculiar to vessel, by the coaxial socket of outer tube, middle thermal insulation pipe and inner tube, formed successively from outside to inside, and its technical characterstic is that described outer tube and inner tube are sheet metal.
In the middle of described, thermal insulation pipe is phenol-formaldehyde resin modified foam insulated pipes.
Described outer tube is Coating Steel Pipe or Stainless Steel Tube or color steel pipe.
Described inner tube is Coating Steel Pipe or Stainless Steel Tube or color steel pipe or aluminum pipe.
Described outer tube thickness is 0.1～0.5mm.
Described interior tube thickness is 0.05～0.5mm.
In the middle of described, thermal insulation pipe thickness is 20～80mm.
During preparation, by airduct size blanking outer tube and inner tube; Expandability phenol-formaldehyde resin modified, surface active agent, stabilizer, curing agent and auxiliary agent are sprayed between outer tube and inner tube by High Pressure Gun head after 25 ℃-60 ℃ heating mix, after continuous production line equipment carries out emulsification, sizing insulation 24 hours, the demoulding, obtain composite pipe; Described expandability phenol-formaldehyde resin modified: surface active agent: stabilizer: curing agent: the mass ratio of auxiliary agent is 100:4:5:25:5; Described surface-active agent is silane and tween serial universal surface active agent; Described stabilizer is NACO or the general solid blowing agent of metallic dust; Described curing agent is hydrochloric acid or sulfuric acid or phosphoric acid; Described auxiliary agent is boric acid or urea or antimony oxide.
Compared with prior art, the utility model has the advantages that: adopt expandability phenol-formaldehyde resin modified foaming thermal-insulating, its thermal conductivity is low, be generally 0.025～0.040 W/mK, good heat insulating, difficult fire, certainly puts out, low smog, flame resistant penetrates, meets fiery without dropping, low toxicity, harmless, there is good thermostability, can be 140～160 ℃ of following long-term uses; Corrosion resistance is strong, the erosion of all inorganic acids, organic acid, organic solvent beyond ability highly basic; Foaming thermal-insulating has good hole-closing structure, water absorption rate is low, vapor-proof penetrating power is strong, when cold insulation, there will not be dewfall, coordinate inner and outer pipe integrative-structure, overall dimensions is stable, variance ratio is little, at serviceability temperature scope inside dimension variance ratio < 1%, structural strength is high, uses safe, indeformable.
