Embodiment Construction

[0021] As shown in the figure, the preparation process of this embodiment is:

[0022] Cutting and blanking→process preparation before welding→plate butt joint→parts hot air welding, extrusion welding→process inspection→assembly welding→finished product.

[0023] Among them, hot-melt butt welding is used for plate butt joint:

[0024] Among them, for PP materials: sheet thickness 3-20mm, welding temperature 180-210°C, preheating time 30-200 seconds, of which sheet thickness 3-10mm, welding temperature 190-210°C, preheating time 30-120 seconds; Thickness above 10mm, welding temperature 180-200°C, preheating time 80-200 seconds; for PVC material: plate thickness 3-20mm, welding temperature 210-240°C, preheating time 40-225 seconds, among which plate thickness 3-10mm , the welding temperature is 220-230°C, the preheating time is 45-150 seconds; the thickness of the plate is more than 10mm, the welding temperature is 210-225°C, and the preheating time is 180-225 seconds; for PVDF...

Abstract

The process of making beta-PPH plate prickling tank includes the following steps: cutting material, preparing for welding, butt jointing plates, welding parts, intermediate inspection, and welding to assembly into prickling tank product. The present invention features that in the making process different welding modes are adopted, including fusing butt welding to connect plates, and hot jet welding and jet welding for welding parts. The prickling tank has no leakage and strength raised by adopting several welding modes.

Description

technical field [0001] The invention belongs to plastic corrosion-resistant equipment, in particular to a method for preparing a β-PPH plate pickling tank. The invention uses β-PPH plates to weld the pickling tank, which has the advantages of long service life, corrosion resistance, no leakage, high strength and the like. Background technique [0002] At present, the acid tank of the stainless steel plant usually adopts: [0003] (1) Acid-resistant rubber sheets are attached to the steel body, and then acid-resistant carbon bricks are built. [0004] (2) The steel body is lined with F4 boards, and then acid-resistant carbon bricks are built. [0005] (3) Steel body plus PVDF lining (using hot rolling molding). Such as Chinese patent 94230327.X, novel hydrochloric acid washing tank, it is also the hydrochloric acid washing tank that is formed by the acid-resistant ceramic tile of furan cement masonry by steel casing, acid-resistant rubber sheet, build by laying bricks or s...
