II Process Requirements January 1 target date for start of field evaluation of improved Pipe Insulation only excluding billets Process requirements are as follows 1 Method of adding coated glass fiber to batch - equipment available at Berlin November 19th for test . : 8 Supply of yarn will come from Textiles chopped - Dust consider delivering roving balls and chopping at Berlin b Examination of material cost factors 2. Pouring method must be with cores out This can be done manually but at a reduction of throughput of 35 to 40 Initial test on Dechanization failed because magnet core holders were inadequate R. J. Paoletti to provide estimate and timing by December 7th completion date set for March 31 1963. Pouring with cores in shows no particular improvement 3 Stress Corrosion - Sodium Silicate powder can be handled in process wet Sodium Silicate cannot due to high consistency Cost is as follows Powder - .07 and Rock .03 Rock would have to be hammermilled to powder Use of % Sodium Silicate dry - process Silicate rock through Jeffrey hammermill and wet mill resultant granules through Bauer mill with Kaylo dust gives no processing problem in pouring operations 4 Use of glass reinforcement is limited to pipe insulation excluding billets Will appraise glass in block starting not later than April 1 1963 coating equipment design should be based on hour useage rate x 730 hours per month 5 Amos to appraise cost of Si in batch by December 7 1962 6 Foss Wilson to establish quality control test for C1 content in batch 7 Amos to replace M_asbestos with other candidate input materials by January 2 1963 8 Absorptivity - testing activity to appraise competitive status of Kaylo Assignments Assignments Smith 1.
