N-34R Magnesium oxide

Basic physical properties:
Ingredients: Magnesium oxide ≥94%
Nature: N-34R is a high purity magnesium oxide, with alkaline powder. It is insoluble in water and dissolves in the slightly acidic solution, so it can be added to the chrome tanning solution to slowly increase the pH to the proper salt base.

Instructions for use:
N-34R is very suitable for chrome tanning, as the degree of automatic adjustment of salt, it can replace some of the base, to improve the degree of salt and not excessive, and then produce chromium powder precipitation on the surface. 0.3% to 0.5% N-34R can be added with the chrome powder or chrome tanning after the use of the initial use should be checked to adjust the degree of salt of the PH, if the appropriate amount can be used to achieve the required salt degree; 34R can be chrome tanned overnight.

N-34R's main advantages:
A) N-34R is a progressive slow increase in PH, and no general salt base adjustment additives shortcomings; it can promote uniform penetration of chromium powder.
B) N-34R will not make chrome tanned leather face friction.
C) N-34R can promote the smooth grain surface, chrome tanning even uniform and even dyeing.
4) the use of N-34R can avoid chrome spot generation.
5) N-34R low dosage and easy to use (can be directly into the drum once), compared with the general amount of alkali more economic value and safety, and save labor to add alkaline salts to increase the salt The
