Description

Glassware surface frosting processing and manufacturing method

Technical field

The present invention relates to glassware surface frosting processing and manufacturing method, relate in particular to, on glass article surface, form the frosting processing and manufacturing method of squamous pattern behind the glass article surface usefulness hydrofluoric acid series solution corrosion.

Background technology

Be glasswork to be immersed in mixed hydrofluoric acid (HF) and hydrofluoric acid ammonium (NH to glass article surface frosted processing in the past ₄HF ₂) frosted liquid in 10～20 seconds, allow glass article surface after extremely short time internal corrosion, form the obscure glass quality, and it mainly is because in hydrofluoric acid (HF) adding hydrofluoric acid ammonium (NH ₄HF ₂) time, the alkalimetal ion that contained in the glass ingredient can stripping, causes having the glass skeleton of small scar to damage under its stripping, and produces evenly tiny concavo-convexly at glass surface, forms the obscure glass quality then.

Yet, because therefore the trickle concavo-convex state on obscure glass surface stays the hand stain in glass surface easily; Again, if when will the glass surface after frosted utilizing screen painting to carry out gold stamping processing, because printing substrate is the obscure glass quality, thereby print surface tarnish, can cause gold that the sensation of sinking is arranged, therefore before printing, must carry out base treatment earlier, make its surface smoothing glossy, then time-consuming thus; Moreover, need carry out the substrate printing filling and leading up the trickle concavo-convex of glass surface for gold stamping part during base treatment, so this substrate printing and gold stamping printing can produce and depart from and gold stamping profile can be swooned hold, undermine value of the product.

Summary of the invention

The invention provides a kind of frosting processing and manufacturing method, at first be ready to by water (H ₂O) 60～80% (weight ratios), hydrofluoric acid (HF) 10～20% (weight ratio), nitric acid (HNO ₃) pretreatment liquid formed of 10～20% (weight ratios), glasswork is immersed about 5 seconds in the pretreatment liquid, remove the impurity such as greasy dirt of glass article surface (visual article characteristic is added and subtracted its time in advance, as 3-10 second etc.), the glasswork that will carry out aforementioned pre-treatment again is soaked in by nitric acid (HNO ₃) 15～40% (weight ratios), hydrofluoric acid ammonium (NH ₄HF ₂) 30～60% (weight ratios), hydrofluoric acid (HF) 0～10% (weight ratio), water (H ₂O) in the frosted liquid formed of 0～45% (weight ratio) and hydrochloric acid (HCl) 0～1% (weight ratio) after 1～5 minute, though washed again and just finish a glass surface after cleaning and stroke with hand and be level and smooth sense of touch, have the squamous pattern to be formed on the mat glass goods of glass article surface form in appearance.

The glasswork of finishing in frosted processing method of the present invention manufacturing, its surperficial sense of touch is about the same with the obscure glass quality of using the processing of frosted in the past, but the glasswork integral surface that manufacturing of the present invention is finished presents the squamous pattern, and can obtain the surface treatment of having very different tastes and interests with in the past frosted quality, even directly do gold stamping processing at machined surface, its printing still has gloss, and the squamous pattern gets so that glasswork presents sparkling surface treatment effect.

Embodiment

The invention will be further described below in conjunction with embodiment, it should be understood that these embodiment only are used for the purpose of illustration, never limit protection scope of the present invention.

The embodiment of glassware surface frosting processing and manufacturing method of the present invention, process with the frosted of stained glass bottle and to be illustrated: vial is soda-lime glass (Na ₂O-CaO-SiO ₂); The operation of frosted processing be according to: pre-treatment → frosted processing → bath → 4 engineerings such as drying are carried out.In the following description, using the solution composition ratio in pre-treatment and frosted processing all is weight ratio.

1. pre-treatment:, vial is immersed in the pretreatment liquid of hydrofluoric acid series in order to remove the glass ingredient of separating out and to remove attached to the oil content on vial surface etc. on the vial surface; This pretreatment liquid composition is water (H ₂O) 60～80%, hydrofluoric acid (HF) 10～20%, nitric acid (HNO ₃) 10～20% compositions.Be immersed in about 5 seconds of the time of pretreatment liquid, but the vial surface has under resin baking vanish or the surface and oil contaminant degree difference, must be immersed in the pretreatment liquid till being removed; Carried out the vial surface of pre-treatment and only removed dirt, its condition of surface with handle before almost do not have different.

2. frosted processing: the vial that picks up in pretreatment liquid is at pretreatment liquid still under the state attached to bottle surface, is immersed in to allow the vial surface corrosion in the frosted liquid; This frosted liquid composition is nitric acid (HNO ₃) 15～40%, hydrofluoric acid ammonium (NH ₄HF ₂) 30～60, hydrofluoric acid (HF) 0～10%, water (H ₂O) 0～45% and 0～1% composition of hydrochloric acid (HCl).The time that is immersed in frosted liquid is about 1～5 minute.

3. flushing: the vial that picks up from frosted liquid, and the resultant of reaction that the reaction between bottle and frosted liquid is produced down can present white and stratiform is adhered to, so want trickle to wash away this layer resultant.

4. dry: as to remove the moisture on vial surface with warm air drying or seasoning.

Through the vial surface after the above-mentioned operation processing is that light is level and smooth, and present the squamous pattern, each scales of squamous pattern looks that the ground-glass appearance that presents with in the past frosted processing is the same, but adjacent scales has different delicate angles, under the reflection of light, scales can sparkle, and because the adding nitric acid that pretreatment liquid did not contain in the past, therefore each scales size of squamous pattern is almost consistent and brightness is increased, simultaneously the vial surface is level and smooth and present the squamous pattern for light, and its sense of touch is compared several no inferior with the ground glass surface by in the past frosted processing gained; Again, the squamous pattern of frosted machined surface clearly, so the dirty meeting of glass surface such as hand stain is not obvious, and the frosted machined surface can directly carry out gold stampingly, and because under the delicate difference of angle of the adjacent scales of the squamous pattern of substrate, gold stamping gloss can occur.

Through frosted processing and glass surface corrosion forms the reason of squamous pattern following inference is arranged, this frosted liquid is nitric acid (HNO about glass ₃) and hydrofluoric acid ammonium (NH ₄HF ₂) reacting to produce hydrofluoric acid (HF) and ammonium nitrate (NH ₄NO ₃); Hydrofluoric acid etch glass-cutting surface, this moment, the resultant of reaction (being mainly silicofluoride) under reaction between hydrofluoric acid and glass produced near glass surface in a large number, in resultant of reaction, insoluble white fluorochemical is membranaceous attached to glass surface, and ammonium nitrate has the effect that suppresses the resultant of reaction between hydrofluoric acid and glass and spread (in the glass frosted processing in the past in frosted liquid, phase reaction between frosted liquid and glass and the resultant of reaction that produces can't form the film as the resultant of reaction on glass surface among the present invention, therefore can in solution, spread), therefore, after glass surface forms resultant of reaction, see through the pore of film, hydrofluoric acid and glass surface react, therefore as in the past, with glass be immersed in frosted liquid during, whole glass surface under the same terms in frosted liquid corrosive situation difference, for the present invention, therefore corrosion can be reacted under the same conditions, under the reaction conditions difference and formed inconsistent squamous pattern; Again, the time length that is immersed in frosted liquid is also very important, if in 1 minute, glass surface look with soak before the same, without any variation, this is because work attached to the film of the resultant of reaction of glass surface, it is comparatively slow to allow corrosive carry out, and when soaking above 5 minutes, glass surface can become too asperities and tarnish, yet the time that is immersed in frosted liquid is if in 1～5 minute, if the long more squamous pattern of soak time can be more clear, in addition by clean remove aforesaid resultant of reaction after, glass surface just presents unthinkable squamous pattern in the processing of frosted in the past.

In above-mentioned frosting processing and manufacturing method, even the unmixed hydrofluoric acid of frosted liquid, the vial surface also can form the squamous pattern, and the squamous pattern that has mixed the vial surface behind the hydrofluoric acid can be clearly, but, if surpass 10% for the hydrofluoric acid mixture ratio in the frosted liquid, the then generation of squamous pattern meeting locality, the zone beyond the squamous pattern is then preceding the same with reaction; Again, if the hydrofluoric acid ammonium mixture ratio in the frosted liquid is 30% when following, the then generation that the squamous pattern also can locality, zone beyond the squamous pattern is then preceding the same with reaction, if and mixture ratio is 60% when above, the then generation that the squamous pattern also can locality, the zone beyond the squamous pattern then with in the past the same obscure glass quality that becomes of frosted processing; In addition, if the nitric acid mixture ratio in the frosted liquid is below 15% or 40% when above, the then generation that the squamous pattern also can locality, the zone beyond the squamous pattern then with reaction before the same, if and the contained water yield is many in the frosted liquid, then the squamous of squamous pattern has the tendency that becomes big; Again, the other purpose of hydrochloric acid is because of hydrochloric acid has the function of destroying above-mentioned white fluorochemical adhesion layer, is inversely proportional to so the ratio of its interpolation and hydrofluoric acid corrode the speed of glass surface, also can make the variation of the different sizes of squamous pattern generating.

Allow the frosted processing of the present invention and prior art do one relatively for knowing, as shown in table 1:
