The present invention relates to a kind of lip-deep composition and method after being used for removing polymer coating and subsequently decorative coating being coated to cleaning from glass surface.
The compositions and methods of the invention are coated in removal has special purposes aspect the polyethylene coating on the glass surface.
Background of the present invention
Glass container for example food cans is manufactured in large quantities with the bottle that is used for wine and other beverage.In manufacture process, the outer surface with glass carries out last coating with slipping agent usually, and this makes glass have low-friction surface, and end article is easier to be transported.
Described slipping agent is that the form with coating applies, and this coating is normally by being coated on the glass surface and handling with tin oxide priming paint subsequently and the polyethylene film that makes.The glass surface that does not have this smooth coating be more rough and have great friction coefficient and the mutual frictional adhesion of adjacently situated surfaces together.This can produce the surface scratch with unacceptable degree, and makes and to be difficult to carry a large amount of glasswares.In addition, the glass surface behind the cut has ugly rough surface.
Handle with coating subsequently, adjacently situated surfaces is free to slide has each other removed above-mentioned difficult thus from.In addition, glass has the outward appearance of no marking more attractive in appearance, and this is normally welcome.The cut of also finding vial has injurious effects to its final strength.Therefore have adequate reasons and make glass manufacturer adopt coating process.
Unfortunately, the glass surface that applies with aforementioned slipping agent can not be further processed and it is to be difficult to especially be fixedly coupled putting on to form between this transparent arbitrarily, printing on glass, paint or the coating material.This makes that be coated in follow-up coating on glass lacks caking property and limited thus and can apply commercial acceptable ornamental polishing agent.
For example, the allocation and transportation of bottle or printing can damage and therefore will be rejected because of commercial being out of favour glass in violent handling process.
For handling the method for glass in ornamental mode in hope, will be obviously advantageously, coating can be removed, or the vial that does not have applying coating can be used simply.This a kind of approach in back unfortunately is not allowed to the glass decoration merchant, because glass manufacturing company least is ready to make the not glass of coating, mainly is to be found difficult to the not cated glassware of carrying.As above-mentioned, the glassware of coating is not easy to bonding mutually.In addition, even the economic benefit of glass manufacturing makes a kind of like this goods be made, the bottle of the huge amount that this method must low production cost then.Owing to these reasons, the use of the glass of smooth coating of no use is unaccepted.
Therefore, only before applying ornamental polishing agent, attempt to remove smooth coating.The prior art that is used to remove smooth coating comprises that the bottle that will apply places longer a period of time surpassing under 500 ℃ of high temperature, for example above 45 minutes.Remove and require outside the high energy, this method is still not satisfied, does not make poor adhesion between glass surface and any decorative coating that applies subsequently because it removes smooth coating fully.
The present invention proposes a kind of composition and method, the smooth coating that is coated on the glass surface with smooth coating can be removed by chemical mode thus.
The present invention's summary
Therefore,, provide a kind of method of removing polyethylene coating, it is characterized in that this method comprises the following steps: from glass surface according to first aspect present invention

(ⅲ) surface after the dry rinsing.
The thickness that is coated to the smooth coating of polyethylene of most of commercial vials is 75-100 μ m.Removing by said method is enough to after this coating make intrinsic decorative coating is coated on the surface.
Than above-mentioned removal technology, the use of the inventive method provides a large amount of advantages.This method obviously consumes energy still less and glass surface is not exposed to and resembles under employed high temperature of above-mentioned removal technology and the abrasive temperature of possibility.
The selection of ammonium acid fluoride is than potential glass cleaner hydrofluoric acid (H for example 2F 2) have an advantage.The hydrofluoric acid aggressivity is attacked glass surface strongly, and it can not be removed polyethylene coating and additionally not dissolve a part of goods itself from glass surface to a certain extent.This may be harmful to the structure and the intensity of vial.Find that it is solution influenced that only use in by the inventive method on the surface of glass on limited degree.Using the further shortcoming of hydrofluoric acid is to be difficult to carrying, storage and waste disposal.
Preferably, ammonium hydrogen fluoride solution is a kind of aqueous solution, and the content of ammonium acid fluoride is 2-10 weight %, and 4-8 weight % more preferably.
Preferably, ammonium hydrogen fluoride solution is contacted 5-60 second with described glass surface.Preferably, ammonium acid fluoride is remained under 25-50 ℃ the temperature.
Normally, with after ammonium acid fluoride contacts, in rinse step, carry out enough rinsings and be removed, and do not have residue to keep to guarantee all loosening in contact procedure coatings.Find in practice, film residue and ammonium hydrogen fluoride solution can be used on pressure be 20-200kPa, flow velocity be every bottle of per minute for 1-5 liter (under the situation of standard wine) spray rinsing several times, the time is 5-90 second.Leave standstill a period of time then, so that before drying, get rid of all waste materials.
Drying stage can carry out and preferably include high velocity, low pressure air source at ambient temperature.
In another aspect of this invention, provide a kind of method, it is characterized in that this method comprises the following steps: glass surface coating decorative coating
