Embodiment 1

[0103] This embodiment discloses a process for increasing the strength and toughness of plastics, comprising the following steps:

[0104] 1) Bake the plastic in an oven at 100°C for 30 minutes;

[0105] 2) Put the material obtained in step 1 into boiling water and boil for 50 minutes;

[0106] 3) Dehydrate the material obtained in step 2, and then bake in an oven at a temperature of 100°C for 30 minutes;

[0107] 4) Place the material obtained in step 3 in soybean salad oil and soak for 3 hours.

[0108] After the plastic is processed by the process method, the torsion force is increased from 120Kg to 250Kg, which is about doubled, and the impact strength is increased by 75% compared with that before toughening.

Embodiment 2

[0110] This embodiment discloses a process for increasing the strength and toughness of plastics, comprising the following steps:

[0111] 1) Bake the plastic in an oven at a temperature of 120°C for 30 minutes;

[0112] 2) Put the material obtained in step 1 into boiling water and boil for 50 minutes;

[0113] 3) Dehydrate the material obtained in step 2, and then bake in an oven at a temperature of 120°C for 30 minutes;

[0114] 4) Place the material obtained in step 3 in rapeseed salad oil and soak for 4 hours.

[0115] After the plastic is processed by the process method, the torsion force is doubled from 120Kg to 240Kg, and the impact strength is increased by 75% compared with that before toughening.

Embodiment 3

[0117] This embodiment discloses a process for increasing the strength and toughness of plastics, comprising the following steps:

[0118] 1) Bake the plastic in an oven at a temperature of 80°C for 50 minutes;

[0119] 2) Put the material obtained in step 1 into boiling water and cook for 30 minutes;

[0120] 3) Dehydrate the material obtained in step 2, and then bake in an oven at a temperature of 80°C for 50 minutes;

[0121]4) Place the material obtained in step 3 in rapeseed salad oil and soak for 2 hours.

[0122] After the plastic is processed by the process method, the torsion force is doubled from 120Kg to 260Kg, and the impact strength is increased by 80% compared with that before toughening.

Abstract

The invention provides a plastic trumpet which solves the problems that trumpets in the prior art are complex in structure, high in production and maintenance cost, high in weight, short in service life and unreasonable in airflow direction. The plastic trumpet comprises a mouthpiece, a tube body, a vertical key piston device, an auxiliary tube and a horn mouth, wherein the tube body is connected with the mouthpiece, the vertical key piston device is connected with the tube body, the auxiliary tube is connected with the vertical key piston device, and the horn mouth is connected with the tube body; the mouthpiece, the tube body, the auxiliary tube and the horn mouth are all made of plastics. According to the plastic trumpet, most of production procedures are completed through machinery equipment, time and labor are saved, production efficiency is high, the product percent of pass is high, quality is good, environment friendliness is achieved, manufacturing processes are simple, material and production cost is low, the weight is low, and the plastic trumpet is convenient to use and carry, waterproof, free of influences of collision, resistant to acid, alkali and corrosion, long in service life and nearly free of maintenance, and is prevented from dropping; meanwhile, the airflow direction is reasonable and smooth, and the plastic trumpet is a rare improved product.

Description

technical field [0001] The invention relates to the field of musical instruments, in particular to a plastic trumpet. Background technique [0002] The trumpet is a commonly used musical instrument. Most of the trumpets currently used are made of copper materials. The disadvantages are: 1. The production process is completed by manual operation, which is not only time-consuming and labor-intensive, but also has low production efficiency, and the product qualification rate Low quality, poor quality, not environmentally friendly, complicated manufacturing process, high material and production costs; 2. The whole is a welded one-piece structure, heavy in weight, inconvenient to use and carry, easy to bruise, and short in service life; 3. In the mouth when playing When the water vapor enters the inside of the trumpet, it will be liquefied into a certain acidic liquid when it is cooled, which will not only corrode the inside of the pipe body, but also corrode the copper piston sl...
