Soda-lime glass infusion bottle inner surface frosting treatment method

Technical field

The present invention relates to a kind of production method of soda-lime glass infusion bottle, relate in particular to the method for a kind of soda-lime glass infusion bottle inner surface sulphur gas frostization processing.

Background technology

Adopt in the market in product annealing forward direction soda-lime glass infusion bottle and throw " calcium sulfate " powder or the processing of tablet frostization, because of dosage grasp and reasons such as reaction times, speed, the deposition of reactant often occur, and be difficult for being scrubbed by the pharmaceutical factory at the bottle inwall, influence quality of liquid medicine, the cost height.

Summary of the invention

The technical problem to be solved in the present invention provides the method for a kind of soda-lime glass infusion bottle inner surface sulphur gas frostization processing, solves " frostization " technique for enhancing of soda-lime glass infusion bottle inner surface, reaches the chemical stability that improves glass.

In order to solve the problems of the technologies described above technical scheme of the present invention be: step 1: adopt common soda-lime glass to be processed into the transfusion bottle of moulding; Step 2: the moulding infusion bottle is delivered to sulphur gas throwing device and is carried out sulphur gas frostization, and control sulphur gas throwing device is to the inner sulfur dioxide gas 0.1--0.2 gram that drops into of bottle; Step 3: the transfusion bottle after the sulphur gas frostization is sent into annealing device annealing.

The concentration of above-mentioned sulfur dioxide gas is greater than 99%, and the working temperature of sulphur gas frostization is at 450 ℃--and 600 ℃.

The invention has the beneficial effects as follows: the settling that adopts the sulfurous gas of throwing in high density in bottle to solve bottle wall internal surface that causes because of factors such as pulvis, tablet injected volume, reaction times is difficult to clean the problem of removal, strengthen the chemical stability of glass, and reduced cost.
