The component of panel will not produce damage.
Wherein, the step 1）In drying temperature be 30-35 DEG C, drying time is 20-25min.Drying temperature is too high,
Meeting damage car component, temperature is too low, then dry not thoroughly, and drying rate is slow.Drying time is too low to improve coating cost,
Drying time is too short, then dry not thoroughly, and cleaning agent is easily remained, and drying temperature of the invention and drying time can be carried effectively
Drying rate high, improves the effect of drying, noresidue impurity.
Wherein, the plated film raw material are Parylene type powder, are according to weight ratio by N powder, C powder and D powder
2：3：2 mix.
Parylene（Poly-p-xylene）, synthetic fibre in trade name handkerchief（Parylene）, it is by chemical vapour deposition technique
The general designation of the thin polymer film with poly- two methylenes penylene structure for preparing, it has extremely excellent electrical property, heat resistance, weather-proof

Interior monomer molecule concentration is higher, and deposition polymerization is faster, but sublimation temperature is higher, and activated monomer molecular kinetic energy is higher, relative to compared with
The molecule of low kinetic energy, during these high-energy molecules have significant proportion to diffuse to cold-trap, on the matrix higher without being deposited on temperature,
Cause raw material availability low.If the speed of distillation is too high, more than rate of cleavage, part ring disome gaseous molecular has little time cracking
Expansion chamber is put into, matrix surface is deposited directly to, the easy formation degree of polymerization is relatively low, poor performance porous polymer.
The sedimentation rate of monomer molecule can be improved with the increase of pressure, but hypertonia, then deposit it is too fast, molecule into
Length is not fast enough, it may appear that vaporific film, and compactness is not enough, therefore the temperature and pressure of evaporation needs a good balance,
Can obtain that compactness is good, raw material utilization rate waterproof membrane high.
Wherein, the step 4）In cracking temperature be 670-675 DEG C, cracking pressure be 9-10Pa.As previously described, such as
