涂层间结合力测试
The
objective
of
this
test
procedure
is
to
detect
problems
with
adhesion
at
the
earliest
possible
stage
and
thereby
prevent
potentially
very
large
problem
showing
up
later in the coating
process.
该测试的目的是通过的结合力测试尽可能早的发现结
合力问题，防止今后油漆在担保期内发生潜在的问题。
The procedure described here is
mandatory for all class
0
Ballast
and
Cargo
Tank
Coatings.
This
applies
not
only
when
application
is
carry
out
at
newbuilding
block
stage,
but also during in-
situ applications at either newbuilding or
M&R.
The
test
is
described
in
detail
in
the
Worldwide
Marine Technical
Bulletin Number T6 of January 1995.
在此描
述的工艺是针对所有
0
级压载舱和货油舱内足
< br>够硬干的油漆，并要求强制执行。此工艺不仅使用于新造船
的分段阶段，而且也可
使用于新造船或修船整船阶段。此测
试在
1995
年
1
月的世界船舶技术
T6
号公告内有详细描述。
3.1
Application of the test
–
where & when
3.1
何时何地进行该测试
Block Stage
You
should
carry
out
the
test
after
completion
of
the
full
coating
system
,when
the
scheme
has
hardened
sufficiently. Two
tests are required per block. One in an area
of good ventilation, for example on the
edge of the block, and
one
in
an
area
where
ventilation
is
more
difficult
and
you
would
expect little air movement.
分段阶段：
应该在整个油漆系统完工
并硬干后进行该测试。
每只分
段应该测两次，一次在好的通风区
域进行，例如分段的边缘
处，一次在通风稍差的地方。
You should not carry out the test on
stripe coated areas,
unless the system
is a
‘
one-
shot
‘
plus stripe coat
applicatio.
在预涂区域不应做该测试，
除非该配
套为一度喷涂加上
一度预涂的施工。
In-Situ
You should
carry
out
the
tests after completion
of
the
full system on both
upper and bottom areas, again choosing
spots
with
good
and
poor
ventilation,
if
poosible.
The
tests
should be carried out
prior to touch up and final inspection,
to allow for repair of the area damaged
by the test.
合拢后
如可能，
在油漆系统完工的情况下，
底部和顶部进行该
测试，也是选择通风好和差的地方进行。该测试应该在补涂
或完工检验之
前进行，以便修补由于测试所破坏的区域。
The
number
of
tests
required
depends
upon
the
tank
size. Common sense should prevail. As a
guide you may try
one test per
500m
2
, but in large tanks
over 2000m
2
you may
take fewer tests.
测试的次数依据舱室的
大小而定。常规做法是，每
500
平方米内一个点，但是在大于
2000
平方米的舱室内你可以
少做几
个点。
3.2
Test Equipment
The
only
equipment
you
will
require
is
a
sharp
knife
with a pointed blade.
3.2
测试工具
唯一需要的工具就是带有尖角的锋利的小刀。

测试方法
1.
You should make
‘
v
’
cut of between 30
0
-45
0
in
the
coating,
ensuring
that
the
cut
penetrates
to
the
steel.
See Figur 6.
1.
在漆膜上切出
30
< br>度至
45
度的“
v
”形切口。
保证切口切至钢板，见图

v
’
cut
2.
Using
the
knife
at
the
Apex
of
the
‘
v
’
cut
to
determine
if the coats can be cleanly separated.
2.
用小刀来测试“
v
”
< br>形尖角处的油漆能否被轻易
的分离。
3.
Rate
the
adhesion
level
according
to
the
pictorial
guide given in figure 7.
3.
根据表
7
评价结合力的级别。
4.
Record the data on the appropriate form
4
．
在相应的表格内记录数据。
You should also ensure that the test
area is properly
repaired, generally by
sanding down and touching up, to
ensure
the integrity of the finished coatings.
应保证做结合力测试的区域得到正确修补，
一般砂磨
后修补，
以确保最后施工的油漆的完整。
3.4
Interpretation of Results
The test results given by the pictorial
guide may vary
from 0-5, as follows:
0
=
No adhesion. This is an adhesion
failure, where no
force is required to
split the coatings and the backs of
