Problems solved by technology

From the structural point of view, the skeleton material is made of nylon cord fabric for tires, which is wound on the inner rubber tube by hand at a certain width and a certain angle. There is a medium film between the cloth and the cloth. The cloth layer is generally four layers. The adhesive force between the hose cloth layers of this structure is poor, and it is easy to delaminate during use. The inner rubber layer cannot withstand strong acid corrosion, the tube is easily damaged, and the service life is short. The longest use time is 200-300 hours.

Abstract

This invention discloses a method for producing tubes of anti-strong acid including processes of matching sizing materials, smelting the material, forming tubes, bushing, winding them to mold, sulfuration process and turning process, in which, the product is soft, elastic and abrasive since the material is made of sizing materials of anti-strong acid, high elasticity and high wearing resistance, the framework material is made of synthetic fiber of high intensity, anti-aging and anti-wearing and erosion to keep fine binding intension with the tube sizing material to increase the entire performance of the tube.

Description

1. Technical field [0001] The invention relates to a production method of a hose pump hose, in particular to a production process for a strong acid-resistant hose pump hose. 2. Background technology [0002] At present, the production process of the strong acid resistant hose pump hose produced in China is to use the ordinary raw material formula to make the rubber compound with the mixing equipment, extrude the inner tube, and add the skeleton material and the outer rubber layer to the inner rubber layer. Rubber hoses are turned into finished products of certain specifications. From the structural point of view, the skeleton material is made of nylon cord fabric for tires, which is wound on the inner rubber tube by hand at a certain width and a certain angle. There is a medium film between the cloth and the cloth. The cloth layer is generally four layers. The adhesion between the cloth layers of the hose with this structure is poor, and it is easy to delaminate during use....
