1.1st, mould is checked, confirms mould therefor correct (there must be label on mould) and check mould integrity.Check
Thickness and surface, if having the defects such as holiday or pin hole dip in a small amount of gel coat with hairbrush mends brush, if problematic timely feedback.Must protect
Mould is intact can come into operation for card.
1.2nd, instrument
0～60kg scales, 0～50ml measuring cups (a set of) or plastic bottle with a scale, gelcoat spray gun, hairbrush, cleanout fluid
1.3rd, ensure operating temperature more than 15 DEG C, it is ensured that below 75%, spraying personnel will check gel coat used to humidity
It is whether correct, whether there is impurity etc. in gel coat, if problematic should feed back in time.
Gel coat (THICKNESS CONTROL is in 0.4mm～0.6mm) is sprayed equably in mould application surface, spraying personnel are got by quota
Required gel coat and firming agent, according to circumstances add 0.8%～3.0% firming agent and stir during use, according to seasonal temperature,
Humidity is done sample and carries out proportioning.It is all it is ready after start to spray gel coat face, after the solidification of gel coat face, check thickness and table
Face, if having the defects such as holiday or pin hole dip in a small amount of gel coat with hairbrush mends brush, if problematic timely feedback.Determine that gel coat face solidifies
No any quality problems can carry out subsequent processing afterwards.
2nd, spread felt, duplicate to put
2.1st, blanking is carried out according to technological document technology for blanking card, Quality Inspector's inspection blanking specifications and models and size are not asked
Paving felt can be carried out after topic, it is different according to the thickness of each product piece, perform according to laying scheme.Glass fibre in same layer
Smooth overlap joint, the gap 30mm～50mm of overlap joint is wanted to forbid docking.Between layers docking port is staggered, the distance for staggering
Requirement >=200mm.When fixing using glue spraying auxiliary, the lay of glass fibre to be completed within 15s.To improve being impregnated with for resin
Property, the consumption reduced by glue spraying, glue spraying to be made the glue of ejection nebulize apply on the surface of glass when in use.
2.2nd, reinforcement 8
According to technical drawing desired size blanking, recruitment is mounted in lay and completes drawing requirement specified location line on felt face
Afterwards, reinforcement 8 is placed, and felt is spread according to technical requirements.
2.3rd, mark time I 9, mark time II 10, marking time III 11
Using marking time I 9, mark time II 10 and III 11 moulds of marking time carry out hand pasting forming and mark time I 9, mark time II 10, marking time III
11, in cutting carry out cutting, polish according to drawing requirement size after curing molding, being placed on inside foaming workpiece and use poly- ammonia
Ester foam (it is black, expect 1 in vain:1 proportioning) filling, and leave honeycomb duct, it is desirable to it is foam-filled it is full, smooth, with type.
