Introduction

Key points of standard evolution and revision

Revision dimensions	2012 edition	2019 edition	Technical significance
Product classification	11 grades	13 grades	Newly added LDNH/LDGH cold-rammed paste to meet the needs of low-temperature construction
Detection methods	7 indicators	9 indicators	Added roasting weight loss detection and improved quality monitoring system
Construction temperature	110±10℃ mainly	17-42℃ low temperature type	Extended low temperature application scenarios

Key performance indicator analysis

Resistivity control requirements

The standard controls the cathode paste resistivity according to the use location:

Steel rod pasteMaximum requirement ≤72μΩ·m (BSGH)
Cold rammed pasteSpecial requirement ≤78μΩ·m (LDNH)
Conventional gap paste is relaxed to 65μΩ·m

Implementation suggestions

Selection and matching principles

GS series hot ramming paste is preferred in high temperature areas
LDNH cold ramming paste is recommended for maintenance conditions BSTN carbon mortar is used for narrow gap treatment

Key points of quality control

Focus on the matching of volatile matter (7-14%) and expansion/contraction rate (ALA-ALc). It is recommended that:

Sampling of sealing performance is carried out for each batch
The roasted specimen must be free of cracks
The penetration test needs to be kept at a constant temperature of 20℃

Standard application case

Overhaul plan for a 300kA electrolyzer

Use GSGH steel rod paste (compressive strength ≥20MPa) in combination with LDNH cold rammed paste to complete cathode assembly:

Construction efficiency increased by 40%
After startup, the voltage drop is stabilized at 3.15V
The cell life is extended to 2850 days
