• Detailed introduction

The acid-alkali resistant belt is usually made of canvas fabric as the belt core, and is coated with acid-alkali resistant covering adhesive. It has the specified acid-alkali corrosion resistance. It is suitable for conveying acidic or alkaline block, granular and powdery materials or products under normal temperature. The covering layer of tape is divided into acid-alkali resistance. A1, A2, A3 categories.

The A1 immersion test solution is 18% hydrochloric acid;

The A2 immersion test solution is 50% sulfuric acid;

And the A3 immersion test solution is 48% sodium hydroxide. The strength specification and width specification of the belt are the same as the general-purpose fabric core conveyor belt. Tape marking example: 300 1000 EP 4 800 4.5 + 3 A 1 indicates that the belt is 300 m in length and 1000 mm in width. The thickness of the cover layer is respectively.4.5 mm and 3 mm, the acid and alkali tolerance class is a1, that is, immersed in hydrochloric acid solution at 50 °c, 18% for 96 h, the volume expansion rate is below +10%, and the intensity change rate is within -10%. At present, this kind of product implements HG/T3782-2005 < acid-alkali-resistant conveyor belt > chemical industry standard.

Product characteristics:

Choose cotton canvas, nylon canvas or polyester canvas as the core, with good elasticity, good groove performance, use of small elongation. The coated adhesive made of acid and alkali resistant materials has good chemical corrosion resistance and good physical properties. Application: Suitable for conveying corrosive materials such as acid in chemical, fertilizer and paper mills. Can also be used in seawater salt
