Formula.
It is specially the dust and impurity for clearing up test plate (panel) surface, polishing test plate (panel) surface etc. to pre-process test plate (panel), is applied with improving
Overlay on the flatness of the glued membrane on test plate (panel).
It is specially to select by the way of manual brush coating or machine brush coating to select glued membrane coating method.
Manual glue brush may be employed, fluid sealant can also be coated uniformly on test plate (panel) by apparatus control glue rifle.In order to
Convenient for later observations, when by fluid sealant coated on test plate (panel), it can be coated and be in strip glued membrane, for the number of guarantee test
According to more sufficient, the larger rectangular-shaped glued membrane of width is preferably applied as.
Being coated on test plate (panel) further preferably includes between glued membrane and allotment paint：Dry the glued membrane；It is sticked on the glued membrane
Thickness datum strip.
Coated on test plate (panel), after forming glued membrane, in order to which fluid sealant is promoted to dry, preventing fluid sealant not dry fluid sealant
It deforms or drips when dry, test plate (panel) can be placed in baking oven and toasted, test plate (panel) is preferably toasted 10 at 110 DEG C
Minute, so fluid sealant can be dried and baking was caused to fluid sealant.
The thickness of the water paint sprayed on glued membrane, the coating thickness benchmark preferably on glued membrane are subsequently read out for convenience
Item, the thickness datum strip can be sealing strip or other easy strip tapes being close on glued membrane.
If the shape of the glued membrane coated out early period is not regular enough, spreading knife or Frictioning device subsequently may be employed, it is right
Glued membrane that is coated and having dried carries out frictioning adjustment, glued membrane is spread to more regular shape, in order to subsequent behaviour
Make and observe.
Allotment paint；
Allotment paint specifically includes：
