Swenson - * Evaluation of Turner and Sevall Fibers for Use in TpwMfte Pipe Attached is a proposed program for evaluation of the C & G3 and C & G 4 Fibers which should be delivered to Manvllle within the next 6 weeks* Tour assistance in carrying out the prograa is requested* If you have any questions, I shall be glad to alt down and discuss the proposal at your convenience* p. 77^1 D.

TRANSITE Pipe without increase in oost* The program is to be in two phases; first, the laboratory point system work using the fibers as processed in the plant, and second, using the laboratory results to formulate a blend or blends, make plants iuna with additional laboratory testing in an attempt to correlate plant vs* Point Value* Since the shipments of 100 tons o C & G3 and 200 tens of C & G4 are to coca to Kanville Plant, this work should be done there using the standard operating blend M&50 as a basis* M&50 M 650* moo g*3 5 * 46 PV Advocate 16*75 * 72 PV 75*0 % m 63 PV = 3*8 * 12*0 * A7.3 _ 63.1 Blend PV The latest samples of T&B fiber show the following Cost/ton delivered C&G 3 G&G 4 PV = 83 PV * 74 $237.38 $191*60 For comparison Jeffrey AX delivers to Manville Plant for $148*80 and with a PV of 63 shows the following* Coat/Point delivered to Manrille C&G3 CftG.4 Jeffrey 4T $2*70 2*59 2.36 After correcting for PV differences, the Pipe Division would still have to use up to 12J5 less C & G 3 fiber to realize equal eoat* As an example, this would mean going from 285 furnish of straight 63 PV Jeffrey to 14*35 to equal PV, and to 12*5$ to equal cost when using C L G3 It is proposed that PV cakes be made to establish a curve of strength vs percent fiber running from about 135 fiber to about 215 fiber* The fibers to be sampled are Jeffrey 4X30, Blend M 650, straight C & G3 and straight C & G4. Points of sampling should include (1) Fiber as received (2) Discharge from Fiber Mixer to willow and (3) Discharge from cyclone to live* bottom bift * It would appear that one willow batch of each of the 3 fibers and the 1 blond would be sufficient* The miring and use of these 4 hatches in the live bottom bin and subsequent use In pipe could be oostroled os to what product they go into and "un-ecoaosoieally* used to prevent loss of product* A standard supply at Manville Plant Rational Cement and Manville Silica should be obtained and set aside for these tests* Pago 2 % Data on McHett and Drainage Tia should also be taken0 The second phase of the proposed program nould be to aelsot frost these basic fiber curve*, a blend cf certain percentage T <r N fibers or blend of T A II fiber plus Jeffrey; This will be selected to equalize strength of ths products at no increase in cost over use of the standard MS50 bland. Plant runs would be Bade using MS50 bland before and after with "special blend A", at a percentage furnish dictated from Phase 1. fiampHwg for laboratory FV Testing would be Bade as in Phase A, plus sasplss of tbs dry stock (fiber, cesftnt,afid silica) being fed to tbs Bochine. Destruction test samples of pipe In Hydrop Flez and Crush should be designated. Panning conditions will be noted. Analysis of the data will lnolude a correlation of the laboratory FT results with tho destruotion tests In tbs plant. If necessary, a second or third blend for plant running and Laboratory FT Testing will be Bade.
