TARGET OF LEARNING ACTIVITY
Educative participant can know kinds of form result painting which often happened Educative participant can know causes of form result painting Teknologi dan Rekayasa
3
KINDS OF RESULT PAINTING
1 Lifting 2 Bruises and chipping 3 Peeling 4 Orange peel 5 Fish eyes Teknologi dan Rekayasa
4
KINDS OF RESULT PAINTING
6 wrinkling 7 water spotting 8 rust under finishing 9 Pitting 10 Blistering Teknologi dan Rekayasa
5
KINDS OF RESULT PAINTING
11 pin point blistering 12 mottled 13 checking 14 run or sags Teknologi dan Rekayasa
6
LIFTING Teknologi dan Rekayasa 1
Surface of object and air of spray gun there are fat, oli, water 2 Spraying pressure too high 3 solven untimely condense. 4 Usage of lacquer acrylic above enamel or on the contrary Teknologi dan Rekayasa
7
LIFTING SOLUTION If the area damage too big or too wide releasing primary paint until plate If damage so small, loosing paint by sandpaper , then paint again. Teknologi dan Rekayasa
8
BRUISES AND CHIPPING Teknologi dan Rekayasa 1
When paint , dirty fly and patch 2 Paint have not been yet mixture swirled flatten 3 Inappropriate solvent 4 The mixture of paint colour do not of a kind 5 The paint have been frozen in can paint not thrown Teknologi dan Rekayasa
9
BRUISES AND CHIPPING SOLUTION
If dirt is not sticky until into can be released with compound If coherent dirt until into have to be rubbed with emery paper # 400 Don‘t be finishing but have to be rubbed and repaint Teknologi dan Rekayasa
10
PEELING Teknologi dan Rekayasa 1
Emerying primery paint surface not yet enough 2 Coherent energy of primary paint less to plate 3 Mixture paint too jell and high spraying pressure 4 Painting too thick Teknologi dan Rekayasa
11
Eliminating old paint and repainting
PEELING SOLUTION Eliminating old paint and repainting Teknologi dan Rekayasa
12
ORANGE PEEL Teknologi dan Rekayasa 1
solvent untimely condense or mixing paint too fat 2 Usage of spray gun uncorectly 3 Room painting too hot 4 Surface of panel still dirty for example there are fat Teknologi dan Rekayasa
13
ORANGE PEEL SOLUTION Emery #800 ~ 1000, then use compound to paint flatten If damage too large, emery #400 with water, then repainting Teknologi dan Rekayasa
14
FISH EYES Teknologi dan Rekayasa 1 Object work not yet clean 2
Dirty patch at paint 3 The dirty from other spraying patch 4 Punctures opening because of too much silicone Teknologi dan Rekayasa
15
FISH EYES SOLUTION Clean paint when wet
After dry, rub with wet emery , repainting again Cleaning the the surface accurately and refinishing Teknologi dan Rekayasa
16
WRINKLING emeriying old paint is not flatten, but but doing repainting
Unequal paint type The paint is not yet dry, but doing repainting emeriying old paint is not flatten, but but doing repainting Teknologi dan Rekayasa
17
Repair all damage until primary paint
WRINKLING SOLUTION Repair all damage until primary paint Teknologi dan Rekayasa
18
WATER SPOTTING Spraying when rain Inappropriate Thiner (solvent)
Air pressure too high Object work so cool Teknologi dan Rekayasa
19
WATER SPOTTING Spraying retarder solvent or paint mixing make less
Release paint and slovent then repainting again Don’t wash object work when paint doesn't dry Teknologi dan Rekayasa
20
RUST UNDER FINISHING Hygiene of surface when painting is less
Rust under paint will make paint lift Hygiene of surface when painting is less Teknologi dan Rekayasa
21
Rub surface until plate
RUST UNDER FINISHING SOLUTION Rub surface until plate Teknologi dan Rekayasa
22
Dampness in spray gun component
PITTING Caused by oil Dampness in spray gun component Teknologi dan Rekayasa
23
PITTING SOLUTION Rub till refinement and repainting again
Doing overhaul to compressor and separator Teknologi dan Rekayasa
24
BLISTERING Solvent and paint do not mixed finely
Painting is doing at fat or oil area Rust under surface Teknologi dan Rekayasa
25
BLISTERING SOLUTION Release all blistering paint
Pass water in air-duct If dampness and temperature is high , use solvent quickly drying Teknologi dan Rekayasa
26
Primary paint has holes
PIN POINT BLISTERING Primary paint has holes the first spraying very thick or not yet dry but have been done next spraying Surface of object work still is dirty, there are fat, oil, water oil, dirt and others Teknologi dan Rekayasa
27
If light damage can be emery;then painted again
PIN POINT BLISTERING SOLUTION If light damage can be emery;then painted again If damage area too big and deep, old paint have to be released then re-painted Teknologi dan Rekayasa
28
MOTTLED Use silicone for finishing Solution :
Before refinished, eliminating drug bast on object surface Teknologi dan Rekayasa
29
CHECKING Barst caused by final finishing spraying too abundant
Spraying too thick above priming Drying temperature too high Teknologi dan Rekayasa
30
CHECKING SOLUTION Rub until fine.
If the barst too big, release till plat Avoid extreme changing temperature Teknologi dan Rekayasa
31
The solvent condense quickly Paint Thick too abundant
RUN OR SAGS The solvent condense quickly Paint heap at one side Paint Thick too abundant Teknologi dan Rekayasa
32
RUN OR SAGS SOLUTION Use fur or rub comb and repainting
Final paint have to dry Eliminating abundant paint, then repainting Teknologi dan Rekayasa
