<p>PURPOSE:To allow judging pellet for acceptance or rejection while the pellet is being bonded on base by using electric conductive adhesive. CONSTITUTION:Powder of Fe, Al, Cu, Ni, etc. is mixed into conventional tar or rosin based thermoplastic resin in amount of 5-80%. If the mixed amount is less than 5%, electric conductivity is poor. If it exceeds 80%, adhesivity is reduced and cutting property by sandblast becomes poor. Using the adhesive allows pellet inspection which is bonded on base plate and therefore is convenient.</p> |
