Double-component pouring sealant storage device

Abstract

The invention discloses a double-component pouring sealant storage device. The double -component pouring sealant storage device comprises a glue sealing tank, a glue injection pipe, an inflation tank and a first valve assembly, the glue injection pipe is connected to the glue sealing tank and extends to the bottom of the glue sealing tank, the glue injection pipe is used for being connected with a glue injection machine, the inflation tank is connected with the glue sealing tank and communicates with the glue sealing tank through the top of the glue sealing tank, and the first valve assembly is connected with the inflation tank, the first valve assembly is arranged between the inflation tank and the glue sealing tank. According to the device, the glue sealing tank can be inflated by arranging the inflation tank and the first valve assembly, after a new glue sealing tank is opened for use and a part of the double-component pouring sealant is used, negative pressure is formed in the glue sealing tank, at the moment, the first valve assembly is opened to open the inflation tank, the inflation tank inflates the glue sealing tank, and the negative pressure in the glue sealing tank is balanced, so that water can be prevented from being mixed into the double-component pouring sealant, and the quality risk and the safety risk caused by wrong manual operation are avoided.

Description

technical field [0001] The invention relates to the field of two-component potting glue storage devices, in particular to a two-component potting glue storage device. Background technique [0002] Common blood purification membrane separation products include hemodialyzer, hemofilter, hemodialysis filter, plasma separator, plasma component separator, dialysate filter, etc. The production process of the above blood purification membrane separation products is basically the same. In the production process of centrifugal glue injection, two-component potting glue will be used. The two-component potting glue includes isocyanate and polyols such as polyols. Polyurethane is prepared by the reaction of the two compounds. Due to the excellent sealing performance of polyurethane, Different liquid passages can be separated, which can play a good role in isolation and sealing. [0003] The chemical properties of isocyanate are relatively active, and can react with moisture in the air ...

AI Technical Summary

Problems solved by technology

In addition, among polyols, polyols, for example, do not directly react with moisture, but polyols are very easy to absorb moisture in the air

If the polyol contains some water, when the isocyanate reacts with the polyol, it will inevitably react with the water in the polyol to produce carbon dioxide, and the viscosity increases during the reaction, making it difficult for the air bubbles to be discharged, resulting in unqualified blood purification membrane separation products
