3.8.1. Weight method
Removing the zinc coating with the weight method is carried out by dissolving the coating in an aqueous solution of the mixture of acids:
sulfuric (HSO
) according to GOST 4204 — 100 g/DM
,
salt (НCl) GOST-3118 — 34 g/DM
or in the inhibited solution of sulfuric acid prepared in the following manner: 2 g of antimony trioxide (SbO
) or arsenic trioxide (As
O
) is dissolved in 60 cm
of hydrochloric acid density of 1.19 g/cm
. The resulting solution was diluted in a volumetric flask with a capacity of 1 DM
to the mark with sulfuric acid with a density of 1.05 g/cm
(the mass concentration of 80 g/DM
).
The bleed solution is replaced as it is exhaustion.
To determine the average surface density of zinc weight method performs the following steps:
a) take samples of wire, degreased in alcohol, gasoline or benzene, wipe with a clean cloth and weighed;
b) dissolve the zinc coating;
C) the samples are washed in cold water and wipe with a clean cloth to remove moisture;
g) weigh the samples and measure the actual diameter, then calculate the average surface density of zinc (), g/m
, by the formula
where is the mass of the specimen of wire (or group of samples) before removing the coating, g;
— the mass of the wire specimen (or group of samples) after removing the coating, g;
— diameter of the wire specimen after the etching of the zinc coating.
Values and
determine to the nearest 0.001 g
with a precision up to 0.010 mm, the average surface density of zinc, up to 0.1 g/m
.
(Changed edition, Rev. N 2, 3)
.
3.8.2. Space-gasometrical method
Removing the zinc coating with three-gasometrical method produced dip samples of wire into the solution at a temperature of 18−20 °C until cessation of gas evolution.
The composition of the bleed solution is specified in claim
To determine the average surface density of zinc volumetric gasometrical method performs the following steps:
a) take samples of wire and measure actual length;
b) degreased wire samples in alcohol, benzene, or gasoline and wipe with a clean cloth;
C) dissolve the zinc coating, completely catching released when the hydrogen;
g) measure the volume of evolved hydrogen gas and bring him to normal conditions;
d) measure the actual diameter of the specimen, then calculate the average surface density of zinc (), g/m
, by the formula
where is the volume of hydrogen at normal conditions (pressure of 760 mm Hg.St., temperature 0 °C), cm
;
— diameter of the wire specimen after the etching of the zinc coating, mm;
— length of sample, mm.
The average surface density of zinc is calculated to the nearest 0.1 g/m.
