What is the operating temperature range of sintered NdFeB shuttering magnets?

Sintered NdFeB is hard, brittle, fragile and corrosion-prone. Please note:

① It is strictly forbidden to hit the magnet with external force or damage the anti-corrosion coating on the magnet surface.

② During assembly, the magnet surface is slightly lower than the iron strip plane, which can effectively avoid impact.

③ Stainless steel protective ring process can be adopted to provide physical protection for magnets against collision and corrosion.

1. Do not confuse rated value with effective value: The nominal value of a shuttering magnet is vertical suction force. To resist horizontal formwork expansion force, it must be multiplied by a reduction coefficient of 0.5. It is forbidden to directly use the rated suction as the horizontal resistance design value.

2. Must be installed tightly: The shuttering magnet must be tightly fitted against the side formwork back plate. The suction surface and mold table surface must be cleaned; iron filings and concrete residues will directly cause resistance failure.

3. Bottom is the main resistance area: The resultant point of lateral pressure is close to the bottom surface, so shuttering magnets must be arranged at the rigid back edge at the bottom of the formwork. The upper tie rod only controls opening deformation and cannot replace shuttering magnets to bear horizontal thrust.
