Corrugated Paper Adhesive

配方组成:

Purina Protein/50
pH= 10.5
Flush mixing tank clean with water and drain empty. Any residual
silicate will coat the protein with a gelatinous film which cannot be
readily dispersed and must be discarded. Add 240 lb (28.8 gal.) water to
mixing drum (22 1/4'' dia.) With agitator running, add 50 lb (1 bag)
Purina Protein slowly to prevent lumping and continue mixing. Add 10 lb
pearl starch slowly, sifting to prevent lumping and mixing until the
entire mixture is smooth. Add 55 lb (4.74 gal) sodium silicate very
rapidly anticipating thickening of the mix when only part of the
silicate is present, and thinning rapidly as the full amount is
dispersed. Continue mixing for at least 15 min to break down this
dispersion which stabilizes at a relatively thin viscosity.

配制方法:

pH= 10.5 Flush mixing drum clean with water and drain empty. Any residual silicate will coat the protein with a gelatinous film which cannot be dispersed and must be discarded due to lumping. Add 18'' (30 gal) water to mixing drum (22 1/4'' dia.) Add 1 qt sodium silicate and 250 ppm disodium ethylenediaminetetraacetate (E.D.T.A.). Mix sufficiently to disperse. Add 100 lb (2 bags) kaolin clay slowly to prevent lumping, agitating continuously for 5 min. Add 1 oz sodium sulfite while continuing agitation. Add 50 lb (1 bag) "Purina" Protein slowly sifting to prevent lumping and continue mixing 5-15 min until entire mixture is smooth. Add 48 lb (4 gal) sodium silicate very rapidly, anticipating thickening of the mix when only part of the silicate is present and thinning rapidly as the full amount is dispersed. Continue mixing for about 15 min to break down the dispersion which stabilizes at a relatively fluid viscosity.
