Ki jan yo kontwole eta a ak fluidite nan silicone
Seleksyon silicone dite
Bay priyorite silikone ak 40-50 rivaj A: twò ba dite (<30A) is easy to deform, and the three-dimensional part of the pattern is easy to collapse; too high hardness (>60a) gen pòv fluidite ak se difisil a ranpli pati yo amann nan mwazi an .
Melanje ak Degasing Tretman
When mixing silicone with color paste and vulcanizer, it needs to be evenly dispersed (mixing time 5-8 minutes) to avoid color paste particles that are too large (>50μm) sa ki lakòz sifas la modèl yo dwe ki graj .
Apre melanje, vacuum degassing (-0.1 MPa, 10-15 minit) dwe fèt konplètman retire bul: bul rezidyèl yo pral elaji pandan vulkanizasyon ak detwi entegrite nan nan modèl la (tankou twou nan mitan an nan lèt) .}}}
