Artificial polymer material flute film

Abstract

The invention discloses a method for manufacturing an artificial polymer material flute film. The method is characterized by comprising the following steps: dissolving a water-soluble high-molecular polymer in water to prepare a sol, and drying the sol on a smooth film forming surface to obtain a film. After the film is dried, the dried film can be cut into a double-layer combined material with aproper size, and the double-layer combined material is stripped when needing to be used; or the polymer film material is stripped, then the stripped polymer film material is cut into a proper size tobe packed, and the polymer film material can be directly taken for use during use. According to the invention, the prepared flute film has the following advantages: (1) the production time is not limited; (2) the quality is unified and controllable, and standardization is easy to realize; (3) aging, yellowing and embrittlement are almost avoided along with the time within one year; (4) a user doesnot need to master a professional film pasting technology; (5) the flute film is stable and is not easy to deform in a playing process; and (6) the size is suitable for fast pasting; and the like.

Description

technical field [0001] The invention relates to the preparation of Dimo, in particular to a preparation method of Dimo ​​of artificial polymer material. Background technique [0002] Dimo is an essential element for flute performance. Traditional dimo is made from reed membrane or bamboo membrane. Natural Dimo ​​has the following six disadvantages: (1) It is time-consuming and time-consuming to obtain materials. For example, reed film is recognized as the best flute film material, and it needs to be collected in the field, cut off, cut, stripped, and removed, which is cumbersome to operate. In addition, the reeds are mostly collected 4-5 days before Xiaoman in early summer. The fiber toughness of the flute membrane is poor when it is early, and the membrane is too old and the timbre is poor when it is late. The annual Dimo ​​collection is limited to one or two days, and the time requirement is too strict. Therefore, the operation of natural flute membranes and the time fo...

Problems solved by technology

This hidden danger urgently needs to be solved by substitutes that can completely adhere to the film, but the film thickness is low, the elasticity is large, and the sound will not be boring.

(6) Most traditional flute membranes are sold as whole reed membranes. When using them, you need to select a membrane tube, cut it into small sections, cut the ring tube from it, and then pull it properly. The use process is cumbersome. If it has been prepared to a suitable size The membrane material is easy to paste directly, which will greatly simplify the use steps, but this requirement is difficult to achieve for natural membrane materials
