Description

Technical Field

[0001] The utility model relates to the technical field of borosilicate glass, in particular to a hydrolysis-resistant borosilicate glass. Background Art

[0002] In the pharmaceutical field, glass is widely used as a packaging material. In particular, its special material properties, such as high transparency, mechanical resistance, low permeability and high chemical stability, are critical to maintaining the quality and even the efficacy of pharmaceutical substances. Pharmaceutical glass containers or primary packaging are usually in direct contact with the contained pharmaceutical substances and therefore must follow strict requirements. They must be able to take out the contents in a suitable manner while minimizing the loss and change of the contents. High borosilicate glass (also known as hard glass) is made by using the conductive properties of glass at high temperatures, heating the glass inside to achieve glass melting, and processing through advanced production processes.

[0003] Some existing glasses are prone to hydrolysis in humid environments, resulting in cracks, discoloration or loss of transparency on the glass surface, affecting its service life and performance. In addition, due to the limitations of its chemical or physical properties, glass can only be used in specific fields or environments and cannot meet a wider range of application needs. In view of this, we provide a hydrolysis-resistant borosilicate glass. Utility Model Content

[0024] like Figure 1-4 As shown, the utility model provides a technical solution: a hydrolysis-resistant borosilicate glass, comprising a glass body 1, the glass body 1 comprising an upper surface layer 2, a silica sand layer 3, a connecting layer 4 and a lower surface layer 5, a placement area 201 and a label area 202 are provided on the surface of the upper surface layer 2, and the connecting layer 4 is fixedly connected to the bottom of the upper surface layer 2, one end of the connecting layer 4 is fixedly connected to a contact plate 401, and the bottom of the connecting layer 4 is fixedly connected to the lower surface layer 5, and the silica sand layer 3 is coated on the edges of the upper surface layer 2, the connecting layer 4 and the lower surface layer 5.

[0025] According to the overall structure of the device, a placement area 201 and a label area 202 are respectively provided on the upper surface of the glass body 1. The placement area 201 is located at one end of the upper surface of the glass body 1 and can be used to place test samples, while the label area 202 can be used to attach labels. The label area 202 neither affects the sample placement position nor blocks the label when the device is taken, which greatly facilitates the device to perform sample experimental detection. At the same time, a contact plate 401 is provided at one end of the glass body 1 to increase the fulcrum of the glass body 1, making the glass body 1 easier to pick up and use. The glass body 1 adopts a multi-layer combination type, which is composed of a variety of material layers. Among them, the upper surface layer 2 of the glass body 1 adopts SiO2, which has a large proportion. The chemical properties of SiO2 are stable, so that the glass body 1 can be used in the chemical and medical fields. Among them, the upper surface 2 of the glass body 1 can be suitable for the inner wall of sample bottles, catheters and experimental containers, which effectively prevents the glass body 1 from being easily hydrolyzed when used in a humid environment.

[0026] like Figure 1-4As shown, the upper surface layer 2 is made of SiO2, the thickness of the upper surface layer 2 is 2mm, the upper surface layer 2 is located on the upper surface of the glass body 1, and the inner center of the glass body 1 is fixedly connected with a connecting layer 4, the connecting layer 4 is composed of three parts, the upper, middle and lower parts, the upper surface and the lower surface of the connecting layer 4 are uniformly melted with colloid, the upper surface and the lower surface of the connecting layer 4 are fixedly connected to the upper surface layer 2 and the lower surface layer 5 through the colloid, the central part of the connecting layer 4 is made of B2O3, the thickness of the connecting layer 4 is preferably 3mm, the lower surface layer 5 is made of Na2O, the thickness of the lower surface layer 5 is 2mm, the contact plate 401 is located at one end of the glass body 1, and the contact plate 401 is fixedly connected with a curved protrusion near one end of the connecting layer 4, the upper surface and the lower surface of the contact plate 401 are both provided with stripes, the silica sand layer 3 is made of silica sand glass, and the silica sand layer 3 is entirely coated on the edge of the glass body 1, and the inner wall of the silica sand layer 3 is fixedly connected to the upper surface layer 2, the connecting layer 4 and the lower surface 5 respectively.

[0027] The upper surface layer 2 is used as the contact surface of the glass body 1, and is made of glass material with a high SiO2 content. The chemical properties of SiO2 are stable, so that the glass body 1 can be used in the chemical and medical fields. The upper surface 2 of the glass body 1 can be used for the inner wall of sample bottles, catheters and experimental containers, which effectively prevents the glass body 1 from being easily hydrolyzed when used in a humid environment.

[0028] The upper surface and the lower surface of the connecting layer 4 are fixedly connected to the upper surface layer 2 and the lower surface layer 5 by a mixed colloid of silicone adhesive and polyurethane adhesive. The upper surface layer 2 and the lower surface layer 5 are adhered to each other without affecting the transparency of the glass itself by utilizing the connectivity and light transmittance of the mixed colloid of silicone adhesive and polyurethane adhesive, so that when the glass body 1 is dropped or damaged, cracks appear on the glass body 1, and the broken glass remains connected without breaking.

[0029] The lower surface layer 5 and the connecting layer 4 have a relatively small proportion of B2O3 and Na2O, which does not affect the proportion of SiO2. Through the design of combination and structure, the anti-hydrolysis effect of the device is further improved.

[0030] Working principle: A placement area 201 and a label area 202 are respectively provided on the upper surface of the glass body 1. The placement area 201 is located at one end of the upper surface of the glass body 1 and can be used to place experimental samples, while the label area 202 can be used to attach labels. The label area 202 neither affects the sample placement position nor blocks the label when the device is taken, which greatly facilitates the device to perform sample experimental detection. At the same time, a contact plate 401 is provided at one end of the glass body 1 to increase the fulcrum of the glass body 1, making the glass body 1 easier to pick up and use. The glass body 1 adopts a multi-layer combination type, which is composed of a variety of material layers. Among them, the upper surface layer 2 of the glass body 1 adopts SiO2, which has a large proportion. The chemical properties of SiO2 are stable, so that the glass body 1 can be used in the chemical and medical fields. Among them, the upper surface 2 of the glass body 1 can be suitable for the inner wall of sample bottles, catheters and experimental containers, which effectively prevents the glass body 1 from being easily hydrolyzed when used in a humid environment.
