Embodiment 1

[0046] A borosilicate glass medical tube, comprising 140kg of borax, 400kg of quartz sand, 24kg of spodumene, 24kg of lepidolite, 252kg of cullet, 3kg of vanadium oxide, 3kg of cerium oxide, 6kg of sodium chloride, 6kg of soda ash, Sodium sulfate 2kg.

[0047] The production method of the borosilicate glass medicinal tube comprises the following preparation steps:

[0048] Step 1: Weigh each component material of borosilicate glass medicinal tube for later use;

[0049] Step 2: adding borax, quartz sand, spodumene, and lepidolite into a blender and stirring evenly to obtain the first mixture;

[0050] Step 3: adding vanadium oxide, cerium oxide, sodium chloride, soda ash, and sodium sulfate to the first mixture and mixing evenly to obtain a second mixture;

[0051] Step 4: adding broken glass into the second mixture and stirring evenly to obtain the third mixture;

[0052] Step 5: Add the third mixed material into the kiln for melting. The melting temperature is 1500°C. The...

Embodiment 2

[0060] The difference between Example 2 and Example 1 lies in the difference in the content of glass components and the difference in process parameters during processing.

[0061] Borax 144kg, quartz sand 410kg, spodumene 28kg, lepidolite 26kg, cullet 224.8kg, vanadium oxide 3.6kg, cerium oxide 3.6kg, sodium chloride 8kg, soda ash 8kg, sodium sulfate 4kg.

[0062] The quartz sand in this embodiment is calcined by natural gas. The specific operation process is to add the quartz sand into the roasting furnace to complete the roasting process, and finally collect the calcined quartz sand for use. The temperature of roasting is best controlled at 820°C.

[0063] The production method of the borosilicate glass medicinal tube comprises the following preparation steps:

[0064] Step 1: Weigh each component material of borosilicate glass medicinal tube for later use;

[0065] Step 2: adding borax, quartz sand, spodumene, and lepidolite into a blender and stirring evenly to obtain t...

Embodiment 3

[0074] The difference between Example 3 and Example 1 lies in the difference in the content of glass components and the difference in process parameters during processing.

[0075] Borax 150kg, quartz sand 420kg, spodumene 32kg, lepidolite 28kg, broken glass 204kg, vanadium oxide 4kg, cerium oxide 4kg, sodium chloride 6kg, soda ash 6kg, sodium sulfate 2kg.

[0076] The quartz sand in this embodiment is selected from the quartz sand roasted by thermal plasma. The specific equipment used is a plasma generator, and nitrogen is used as the discharge gas. The gas enters the plasma generator after the flow is controlled by the rotameter. , the gas is ionized in the plasma generator to generate a high temperature plasma jet. The temperature at the jet outlet is 3500°C, and the quartz sand enters the plasma jet outlet from the feeding outlet through the valve control, and is rapidly heated to above 1600°C by the plasma jet in the reactor section. The treated quartz sand enters the lo...

Abstract

The invention relates to a borosilicate glass medicinal tube and a production method thereof, and relates to the technical field of medicinal tube production. The problem is solved that glass residuesare generated during sheet stripping of existing medicinal glass tubes. The borosilicate glass medicinal tube specifically comprises following components including borax, quartz sand, spodumene, lepidolite, cullet, vanadium oxide, cerium oxide, sodium chloride, sodium carbonate and sodium sulfate. Sodium sulfate added in the components has a chemical reaction with alkaline substances on the surface of the glass in sulfur dioxide generated at high temperature to generate sulfate easily washed by water, the alkali amount of the surface of the glass is reduced accordingly, the occurrence of a stratification phenomenon is further reduced, and therefore the occurrence of a sheet stripping phenomenon is reduced.

Description

technical field [0001] The invention relates to the technical field of production of medical tubes, in particular to a borosilicate glass medical tube and a production method thereof. Background technique [0002] Glass bottles and jars are familiar and favorite packaging containers. It is mainly used for packaging liquid, solid medicine and liquid beverage products. [0003] Drug packaging plays an important role in ensuring the quality of drugs and ensuring the safety of human medication due to bonding and contact with drugs. Its chemical stability directly affects the quality of medicines. Pharmaceutical glass is divided into high borosilicate glass, neutral borosilicate glass, low borosilicate glass and soda lime glass according to chemical composition and product performance. Neutral borosilicate glass has become the new favorite of injection glass packaging materials because of its excellent characteristics. [0004] Glass is the most commonly used packaging contain...
