Problems solved by technology

[0021] Investigating the above-mentioned coating process method of sealing the place to be sealed by first applying the sealing material to the place to be sealed, and then solidifying it into a film by a certain material or chemical method, it can be found that the above method has a large number of film tubes and is exhausted. In the case of dense cloth, it is difficult to apply the sealing material, the film forming effect is not good, and the sealing effect is not good

Embodiment

[0055] Such as figure 1 A schematic flow chart of a method for generating a sealing film sleeve provided by an embodiment of the present invention is shown in the following:

[0056] A method for generating a sealing membrane sleeve, which is used to generate a sealing membrane sleeve at the joint between a connecting piece and a connected piece, comprising the steps of:

[0057] S1) adding the sealing film material into the organic solvent and the binder, stirring evenly to make a sealing emulsion;

[0058] S2) apply the sealant to the joint between the connecting piece and the connected piece, and connect the connecting piece and the connected piece;

[0059] S3) place the connecting piece and the connected piece that have been connected together in an air-conditioned environment, and at a temperature lower than the boiling point of the organic solvent, wait for the organic solvent to volatilize, and initially fix the connection between the connecting piece and the connecte...

Abstract

A method for producing a sealing film sleeve, which is used to form a sealing film sleeve at the joint between a connecting piece and a connected piece, comprising adding a sealing film material to an organic solvent and an adhesive and stirring to form a sealing emulsion, and applying the sealing emulsion on Connect the connecting piece and the connected piece at the joint between the connecting piece and the connected piece, place the connected piece and the connected piece at a temperature lower than the boiling point of the organic solvent until the organic solvent volatilizes, and initially fix the gap between the connecting piece and the connected piece After the connection, wrap the non-sealed area between the connecting piece and the connected piece with aluminum foil and adhesive tape, and then apply sealing emulsion on the outside of the connection between the connecting piece and the connected piece and wait for the organic solvent to evaporate, and seal the connecting piece and the connected piece The pieces are placed together in a baking oven and baked with a gradient heating method to cross-link the sealing film material to form a film. Repeat the last two steps until a sealing film sleeve that meets the requirements is produced. The sealing membrane sleeve produced by the invention has high compactness, good sealing performance, low sealing failure rate, simple operation and improved work efficiency.

Description

technical field [0001] The invention relates to a method for generating a sealing membrane sleeve, in particular to a method for generating a sealing membrane sleeve at the joint between a connecting piece and a connected piece, and belongs to the technical field of sealing membrane sleeve production. Background technique [0002] Sealing is a technical problem that often needs to be faced in the production and use of many products. For example, in membrane separation technology, a large number of sealing problems of membrane modules are involved. [0003] Membrane separation is a new separation technology that rose rapidly after the 1960s. Membrane separation technology has been widely used in food, medicine, biology, environmental protection, etc. , chemical industry, metallurgy, energy, petroleum, water treatment, electronics, bionics and other fields have produced huge economic and social benefits, and have become one of the most important means in today's separation sc...
