Thermal coating.
Hot applied in bottle blowing molding conducted before and after annealing treatment.
After molding of glass bottles in slowly cooled to 500 ~ 600 ℃, the metal coating agent (
Such as tin oxide, titanium oxide, tin chloride, etc. )
Spraying on the surface of the container, a certain thickness of the protective film formation, enhance the surface strength about 30%, and can make the bottle stands long water, water to wash.
with the cold. Cold besmear is on glass bottle after annealing, the single stearate, polyethylene, oleic acid, silane, silicone or other polymer emulsion paint mist, attached to the glass on the surface of a certain temperature ( The bottle temperature depends on the coating material, which is about 21 ~ 80 & deg; C) , form a protective layer of abrasion resistance and lubricity.
frosting. Frosting is in the process of glass bottles cooling spraying carbon tetrachloride, or during a annealing furnace sulfur dioxide, both are available on the surface of the bottle and alkaline oxide reaction, make the sodium ion precipitation and forming glauber's salt particles on the surface of the glass ( The turbidity of white powdery Na2S04) , after flushing in addition, due to the alkaline reduce the surface chemical stability enhancement.
the organic silicone coating processing. Using organic silicon evaporation coating glass surface or all can form organic polysiloxane with silicone dipping hydrophobic membrane and aggregation ( Si02） 。 Silica film, by common silica key connected with the glass surface. After heat treatment of the organic linkers can evaporate the remaining silica membranes can be filled in the crack, the good hydrophobic can avoid active medium diffusion and the surface cracks in the crack healing ( Commonly known as heterogeneous healing) , not only has a considerable improvement in the glass strength and chemical stability, also make the glass with special optical performance and shock resistance. Commonly used organic silicon solution with methyl fluorine silane, dimethyl dichlorosilane, two fluorine diphenyl silane and phenyl trichlorosilane, etc. 005 mm, the container weight under the compressive stress increased 10 ~ 12 pa. Under internal pressure are the same, for the recovery of standard glass bottles can be caused by the weight of 420 g is reduced to about 300 g. Glass bottle weight decreased by 25% ~ 30%. At the same time as the plating film is very thin, this kind of glass containers oven will not cause any environmental problems, as a result, online polymer coating containers can be incorporated into the standard recycling process.
