Abstract
The invention relates to the fields of energy conservation and environment protection, in particular to the glass surface processing field, in particular to a float glass spraying technology. As float glass at present has the excellent quality, the float glass spraying technology is expected to be provided, and the float glass with film layers with different functions is accordingly formed. In particular, the problems that after a traditional spraying method is used in the float glass, small liquid drops are easily caused to influence the leveling effect, rainbows are easily caused on the film layers, and the sprayed film layers are easily deformed are solved through the brand new float glass spraying technology, the float glass can be well sprayed with the film layers, and the float glass with the excellent quality is obtained.
Description
Technical field
The present invention relates to energy-conserving and environment-protective field, particularly relate to glass surface treatment field, more specifically relate to a kind of float glass spraying coating process.
Background technology
The moulding process of float process is to complete in the molten tin bath that passes into shielding gas.Float glass is widely used, and is divided into colored glass, float glass process silver mirror, float glass/automobile keep out the wind level, float glass/all kinds of deep processing levels, float glass/scanner level, float glass/plated film level, float glass/mirror level processed.The moulding process of float glass is to pass into shielding gas (N
2and H
2) molten tin bath in complete.Melten glass continuously flows into and swims on the tin liquor surface that relative density is large from tank furnace, and under gravity and capillary effect, glass metal spreads out, shakeouts, forms that upper and lower surface is smooth on tin liquor face, sclerosis, the cooling rear transition roller table that drawn.The roller turn of roller platform, enters annealing furnace glass ribbon pull-out molten tin bath, through annealing, cutting, just obtains float glass product.
Summary of the invention
The present invention is directed to the excellent properties that current float glass has, wish to provide a kind of spraying coating process of float glass, there is the not float glass of same-action rete thereby form.Particularly be used for, after float glass, easily causing small droplets for conventional spray paint method, affect levelling effect, rete easily produces rainbow simultaneously, spraying rete is easier to the problem of distortion, and a kind of brand-new float glass spraying coating process is provided, and mainly comprises the following steps:
S1, cleans float glass, and using the air surface of float glass as to be sprayed; Described cleaning float glass specifically comprises four steps, S1-1, adopt washing composition to remove oil stain on glass surface, S1-2, adopt cerium rouge polished glass surface, and clean and remove unnecessary cerium oxide, S1-3 adopts the washed with de-ionized water glass of resistivity >=10 Ω m, S1-4, constant temperature drying float glass at the temperature of 50 DEG C;
So-called float glass air surface refers in float glass making processes, towards the one side of air.Here washing composition can adopt the washing composition of general conventional wipe oil.
S2, select high-pressure air spray gun, adopt the mode back and forth spraying at a high speed, spray the whole glass space of a whole page, the speed V1 wherein spraying for the first time: the speed V2=1:2 of spraying for the second time, spray for the first time spray material used and account for 2/3 of total spray material, spray for the second time spray material used and account for 1/3 of total spray material;
Wherein total spray material M=(d × ρ) ÷ n × S, wherein d is the spray-coating surface thickness (nm) presetting, the density (g/cm that ρ is film material
3), the concentration (wt%) that n is spray material, S is transparency area (cm to be sprayed
2);
Therefore, V1=L ÷ (M × 2/3), V2=L ÷ (M × 1/3); S3, solidification treatment under the temperature condition by the float glass having sprayed more than 200 DEG C, does not produce impression of the hand until directly wear gloves touch glass spray-coating surface, shows to have solidified;
S4, tempering is processed and is packed;
Here we to require each spraying be all the spraying of the whole glass space of a whole page, after justifying has sprayed, thereby fill up the gap not spraying to for the first time, thus the unfairness problem of avoiding small droplets to cause.
Further, the present invention also considers many spray guns service condition that may exist in production, further provide and also included X and prop up spray gun, single gun traffic that described X props up spray gun is that Y(g/s props up), accordingly, described V1=V1=L ÷ (M × 2/3 ÷ X ÷ Y), the technology of V2=L ÷ (M × 1/3 ÷ X ÷ Y) is open.
Wherein, concrete spray material can be selected some conventional applicable spraying systems by rete as required, such as silicon fluoride system.
Adopt spraying coating process disclosed in this invention, rete can well be sprayed on float glass, obtain having the float glass of excellent properties.
