E4303, E4313 Nickel Electrode welding material in China's leading product, accounting for 80% of the total production of electrodes around. Recent years, the welding industry are looking for with little or no use of rutile titanium dioxide or by high prices of raw materials to reduce production costs way, sepiolite, clay, pyrophyllite, etc. used in non-metallic mineral aluminosilicate E4303, E4313 welding electrode in, have achieved a certain effect, but not completely smooth and has good plasticity. And sericite overall performance is much better, and help improve the E4303, E4313 welding quality.

1: lamellar mica is potassium aluminum silicate structures for KAl2 [Si3AlO10] (OH, F)

Suitable for welding rod industry, the chemical composition of sericite as follows:

Chemical composition SiO2Al2O3K2OH2OSP

Content (%) 50-6025-307-11 ≤ 5 ≤ 0.03 ≤ 0.03

2: GTS sericite applications and features:

2.1 and sepiolite, clay, pyrophyllite, compared with higher levels of sericite in K2O (pyrophyllite, 7.41%; sericite ,7.5-11%; clay, sepiolite does not contain K2O), and therefore have a lower ionization potential, in the arc burning process, facilitate the provision of conductive ions, so that the arc burning stable.

2.2 GTS sericite S, P low impurity content (S content of 0.015-0.018%), help to reduce the deposited metal in the S, P, reducing its tendency to crack, to improve crack resistance.

2.3 low water swelling (pyrophyllite, 70.5%; sepiolite, 5.2%; titanium dioxide, 32.6%; sericite, 4.3%), medicine for the skin to reduce Welding Electrode Manufacturers crack beneficial.

2.4 adsorbed water content is low (after 110OC × 2h after baking, moisture% is: pyrophyllite, 1.8; clay, 5.2%; sepiolite, 5.8%; titanium dioxide, 2.4%; sericite, 2.5%), can improve its moisture resistance properties, reduce the spread of deposited metal hydrogen content, lower stomatal sensitivity, improve the level of X-ray film scratches.

2.5As was fine scaly, with a certain degree of flexibility, plasticity, increase the welding rod coatings and slip in the powder cylinder flow, pressure applied to improve its performance.

2.6GTS sericite particle size distribution, excluding large particles of foreign impurities in the arc burning does not produce burst, thereby reducing spatter, while reducing the burning of the sound.

    Conclusions: GTS sericite is a new drug skin electrode material. It contains 7% -11% K2O, can improve the arc stability, reduce splash, welding process to improve the performance of the production process to solve the electrodes of the electrode drugs often cracking skin problems, E4303, E4313 electrode in applications such as acid recommended ratio of 3% -5%, can improve the coating slip, viscosity, instead of titanium dioxide, reducing the cost of welding rod.
