Abstract
The present invention discloses an anticorrosive radiator made of steel. After an organic solvent containing zinc is filled into an inner cavity of the radiator by filling equipment, a double-protection anticorrosive coating which simultaneously have a chemical protection function and a physical protection function is formed on the inner wall of the radiator. The anticorrosive performance of the radiator is enhanced, and the service life of the radiator made of steel is greatly extended. The anticorrosive radiator has favorable economical performance.
Description
The present invention relates to the heating equipment radiator, refer more particularly to a kind of anticorrosion heat sink made of steel.
Steel radiator has developed since the eighties rapidly; be to use one of more several radiators at present; has lightweight and portable in volume; good looking appearance; the advantage of good heat dissipation effect; but its maximum shortcoming is that corrosion resistance is relatively poor; service life is short; the steel plate thickness of making radiator generally is 1.5 millimeter; in the higher boiler circulation of oxygen content, use after 2 to 3 years; just can cause that the radiator wall seeps water and maintenance difficult because of the spot corrosion perforation; bring very big trouble and corresponding economic loss to the user, solving the anticorrosion problem of radiator at present mainly is to adopt the physical protection method, is coated with at radiator inwall exactly and brushes various organic coatings; radiator inwall and water are completely cut off, thereby avoid the steel body to contact and corrode with oxygen.Also there is the method for chemical protection of employing to realize anticorrosion purpose; for example Chinese patent CN1225998A discloses a kind of anticorrosion heat sink; be to adopt method of chemical protection; this patent is that the metal bar that electrode potential of insertion is lower than iron in radiator is an anode; and be connected with radiator, constitute galvanic cell after, anode is slowly dissolving in water; utilize sacrificial anode to come the oxygen in the consumption systems or absorb oxygen, thereby realize anticorrosion as the radiator wall of negative electrode.More than two kinds anticorrosion shortcoming arranged all; because steel radiator internal structure complexity; and internal face is uneven; can make organic coating be difficult for thoroughly covering; make the corrosion of radiator appearance point easily and cause seepage; this is the shortcoming that physical protection is difficult to overcome; and metal bar is that protection domain is limited as the shortcoming of the method for chemical protection of anode; promptly around metal bar, protect effective; wall away from metal bar then is difficult to obtain protection; and after metal bar participates in solubilizing reaction, need often to change, easily steam generator system is brought pollution.
The objective of the invention is to overcome above-mentioned radiator corrosion-resistant shortcoming, provide a kind of employing physical protection, thereby realize having antiseep, make simply the anticorrosion heat sink made of steel of long service life in conjunction with chemoprotectant dual anti-corrosion protection method.
The present invention by the following technical solutions in order to achieve the above object; a kind of anticorrosion heat sink made of steel; comprise the steel radiator body that has delivery port and water inlet; be characterized in that one pack system is contained the zinc organic solvent to be passed through by agitator tank; delivery pump; the bulking system that radiator shaking device and recycling can are formed pours in the steel radiator inner chamber; make on the radiator inwall coating one deck can realize the bottom cathodic protection; the duplicate protection corrosion-inhibiting coating of surface layer barrier protection; containing the zinc organic solvent is greater than 80% by content; less than 96%; granularity is less than 15 μ m; purity is dissolved in the resinene solvent that content is 4%-20% greater than 99.99% pure zinc powder and is constituted, and the thickness that contains the coating that the zinc organic solvent forms on radiator inwall should be not less than 40 μ m.
Antiseptic principle of the present invention is as follows: contain the zinc organic coating and the radiator metal body has good bonding force; when containing the zinc organic coating as primer coating; zinc ion has precedence over iron ion and water oxygen react dissolving and oxygen consumed; can realize cathodic protection for the metal iron rule; and zinc has that good mixing and medium-sized mixed with resin form when containing the zinc organic coating as surface layer; it is isolated that resinene wherein can carry out physics to the internal face of radiator; avoid steel plate directly to contact and corrode, thereby form physical protection with oxygen in the water.One contains the function that zinc organic solvent coating has possessed chemoproection and physical protection simultaneously, has realized radiator is carried out the anticorrosion purpose of duplicate protection.
Because above-mentioned anticorrosion heat sink has adopted and has contained the zinc organic coating forms the corrosion-inhibiting coating with double protection functions on radiator inwall technical scheme; make the steel radiator antiseptic property improve greatly; can reach 15-20 its service life; and can seepage not take place because of corrosion; the novel steel radiator of the not only practical manufacturing of the technical program; also can be used for the existing steel radiator of restoration updating, its antiseptic property improves greatly, remarkable in economical benefits.
Below in conjunction with embodiment in detail the present invention is described in detail; with zinc content is 85%; the resinene solvent be 15% form contain the zinc organic coating; inject agitator tank; stir after adding an amount of diluent; start canned pump then; utilize reversal valve control with the water inlet injection lumen of radiator of organic coating by radiator; make and contain zinc organic coating coating radiator inwall; radiator is after the vibrating device vibration; flow into recycling can by radiator outlet; make fully to cover on its irregular inwall to contain spelter coating,, have duplicate protection corrosion-resistant radiator thereby finish so that form uniform corrosion-inhibiting coating.
