(1) baking temperature
The production process of cast tube is the very strong production process of continuity, and fast quickly cooling after molten iron molding is first injected in grinding tool
But, blasting treatment is then carried out, is being painted.So cast tube inherently has certain temperature generally in 60-70 in spray painting
Between DEG C, and will lead in this way water paint spraying moisture on cast tube surface quickly volatilize cause surface of the paint film occur pin hole or
Bubble, but moisture can't evaporate completely, need 80 DEG C of baking to can be only achieved formulation hardness and piled up.If no
The time is piled up in the packing that carrying out subsequent baking moisture cannot come out completely just after will affect cast tube spray painting, in some instances it may even be possible to lead to stacking
Occurs adhesion after packing.And be exceedingly fast after spraying 5 minutes can table for the aqueous cast tube outer wall anti-decaying paint rate of drying of my company research and development
It is dry, so being sprayed on is not in pin hole and bubble on the cast tube of temperature.It is subsequent to can reach formulation hardness with 40 DEG C of bakings
It is piled up, so saving the energy again.
(2) ambient humidity
Since the painting environment of cast tube is largely that spraying is relatively high having good exhaust system humidity in the room of workshop,
And humidity directly results in greatly the decline of water paint rate of drying, or even to have part water paint that can return after the drying viscous.And I grinds at company
It joined special phenol siccative in the aqueous cast tube outer wall anti-decaying paint of hair.Make after the contact with moisture to paint film in air quickly
Hydrolysis, paint film quickly determines film after reaction.
(3) blasted rough degree
Cast tube is inherently extremely coarse, and cast after need to carry out blasting treatment, dispose cast tube cast when grinding tool on
Determine film object.This makes the roughness on cast tube surface generally between 60-80, needs according to the anti-corrosion theory paint film of anti-decaying paint than thick
Rugosity high 30% can just guarantee its antiseptic property, that is to say, that general aqueous anticorrosion paint will spray to 80-100 μm just can be with
Guarantee antiseptic property.But water paint the phenomenon that will appear sagging if spraying to 80 μm or more, and the solid of water paint
Not Gao Xiang spray to 80 μm or more it is also highly difficult.And the principle that the aqueous cast tube outer wall anti-decaying paint of my company's research and development passes through infiltration
As long as allowing paint solution to penetrate into cast tube surface forms protection so spraying to 40 μm or so perfect covering cast tube surfaces.
Aqueous cast tube outer wall anticorrosive paint of the invention is possessed compared with prior art to be had the active effect that
1, film of the present invention has excellent antiseptic property, plays a protective role to cast tube, avoids moisture, salt in atmosphere etc. pair
The corrosion of ground, prolongs the service life.
