1. product Introduction

Tantalum clad plate is a clad material composed of tantalum plate and steel plate or stainless steel plate or copper plate by explosive welding.Tantalum clad stainless steel plate, tantalum clad copper plate are widely used in waste sulfuric acid concentration and recovery system. From the economic point of view, tantalum and its alloys can be used in a variety of ways: the most economical and widely used as movable lining; the integral structure when it can not be replaced by others; when manufacturing pressure vessels, composite materials can be made with steel and stainless steel by explosive compounding.

When making tantalum clad steel plate or tantalum clad stainless steel plate, need a Titanium layer between tantalum and carbon steel, because tantalum and carbon steel are two different metal which can not be welded together directly, using titanium as a medium can unit these two materials together.

3. Package

General principles of packaging

1）The packaging of the product shall be able to ensure that the product will not be loose, lost, damped and deformed during transportation and storage.

2） The products in the same box, bundle and package shall be the same batch of products. Under special circumstances, when several batches of products are packed into the same box, they shall be bundled and packed separately, with clear marks.

3）When packing in boxes, the walls of the boxes should be lined with polyethylene plastic film or neutral moisture-proof paper. When the product is packed, all the pieces in the box should be filled and fixed with paper or foam plastics, so as to avoid collision and collision. After packing, the packing materials on the four sides should be folded up.

Cover 1 to 2 layers of moisture-proof paper on the top, and then cover and seal the box

4） When connecting the wooden packing boxes, the nail position should be arranged step by step, the nail cap should be pushed back, the nail tip should be turned upside down, no exposed nails are allowed, and the outside of the box should be reinforced with soft steel belt or double metal wires

5）The structural shape of metal packing box or shelf shall be convenient for shipment, and it shall have sufficient strength, safety and reliability

Packing method: plywood wooden case or steel bracket
