Abstract
A kind of antisepsis technical method of metal pipe material, the invention is characterized in tubing and steel sash are handled through phosphatization that dipping lacquer is handled, after the plastic powder high-pressure static spray treatment, with plastic spraying in the metal surface, its advantage: the internal and external anti-corrosive of steel part and incrustation performance are good, long service life, and coating adhesion is strong, the mechanical strength height, good hand touch, color is various, is current comparatively ideal technological method for processing.
Description
The invention belongs to the common metal anticorrosion technique, be specially adapted to the reason place, surface of tubing and steel sash (door).
The external process that adopts all is earlier steel strip surface to be made the color metal steel band of plastic surface layer with roll coating process at present, as the raw material of making various tubing and hollow steel window (door) special section tubular product, again this raw material are made special section tubular product, because of there is plastic layer its metal surface, so can not adopt the welding method moulding, can only adopt the counterpart interlock to add the rivet clasp method and make the special section tubular product moulding, more because of the existence of its plastic surface layer, in all processes of making tubing and steel pipe, all must not adopt welding method, and can only adopt screw attachment, thereby in the production process of making tubing and steel sash (door), though because of its surface plastic coating, the outward appearance grace, the anticorrosion life-span is long, but the manufacturing process complexity involves great expense, and is unsuitable for promoting the use of in general residential construction.
Domestic present hollow steel window (door) method for anticorrosion treatment is being updated, initial stage is only to make the way of finished product window (door) back with manual painting, with steel sash (door) outer surface brush layer antirust paint, sell then, because of abdomen in its window (door) material is not done any preservative treatment, cause shorten greatly its service life, after improving, develop into the abolishment mopping and adopt the drill traverse method, order window (door) inner and outer pipes wall surface on an empty stomach all has rust preventive coating, this kind process is a a progressive step again than mopping, make also corresponding increase to some extent in its service life, but because of inside pipe wall can't be done processing of rust removing (mechanical derusting method) before dipping lacquer, so the adhesive force of rust preventive coating and metal surface is also not really strong, in use, still can cause the metal eremacausis, cause enamelled coating to come off, influence service life, the anticorrosion method that generally adopts of present domestic steel sash (door) is with product elder generation phosphatization, the technique processing method of back dipping lacquer, but various paint, because of its mechanical strength low, easy aging cracking, once japanning its life-span of back also only can keep 2～3 years also mopping once more later on, its shortcoming: method is outmoded, antiseptic property is poor, the expense of taking a lot of work material, and general skyscraper is difficult to carry out.
Purpose of the present invention provides a kind of new tubing and hollow steel window (door) antisepsis technical method, to solve shortcomings such as present hollow steel window (door) antiseptic property difference.
The concrete process of the present invention at first adopts phosphatization to handle, and finishes oil removing, and the effect of rust cleaning, scrubbing is done dipping lacquer then and handled, and tubing and hollow steel window (door) are immersed in the phenolic antirust paint of formulated, does electrostatic spraying at last and solidifies and handle.
Its advantage: do not change the rolling mill practice of former tubing, do not change the production technology of former hollow steel window (door), internal and external anti-corrosive and incrustation performance are good, long service life, and paint adhesion is strong, the mechanical strength height, good hand touch, color is various.
The present invention's embodiment:
With hollow steel window (door) is the specific embodiment of material.
1, phosphatization is handled: at first tubing and steel sash (door) are immersed in the phosphatization liquid of special preparation, soaked at normal temperatures 10～30 minutes, effect is oil removing, rust cleaning, scrubbing and forms phosphating coat in the metal surface, strong adhesion between this film and the metal, road technology is laid strong basis under giving, again through nature and artificial drying.
2, dipping lacquer is handled: tubing and steel sash (door) after phosphatization is handled immerse in the phenolic antirust paint of formulated, and 5～20 minutes at normal temperatures, the oven dry of heating at last.
3, electrostatic spraying: adopt the plastic powder high-pressure static spraying, tubing after top two PROCESS FOR TREATMENT and steel sash (door) are carried out spray treatment, spraying raw material is a polyester powder, behind high pressure electrostatic painting, powder is coated on the metal surface uniformly, carries out solidifying in 15～30 minutes at 160 ℃～180 ℃ and handle.
The present embodiment advantage: this antirust paint and these plastics play good anticorrosion and decoration effect together, and antiseptic property is good, and is durable in use, and cost is low, and technological process is simple.
Claims (4)
1, a kind of antisepsis technical method of metal pipe material is that metal pipe material is handled through phosphatization, dipping lacquer, the invention is characterized in after phosphatization, dipping lacquer are handled and handles through plastic powder high-pressure static spraying and curing.
2, according to a kind of antisepsis technical method of the described metal pipe material of claim 1, it is characterized in that phosphatization is handled soaked 10～30 minutes at normal temperatures.
