Definitions

  • the product of the above described reaction is a multi-phase mixture (i.e., two different forms or phases are present in the product) , predominantly of foshagite, with some xonotlite.
  • small, haystack like particles containing complex multi -phase crystalline optical fibers are produced that can be advantageously employed in papermaking for coating and for wet end fillers.
  • the hydrothermally produced multi-phase crystalline optical fibers are vastly improved over previously produced hydrothermal calcium silicate hydrates of which I am aware, at least with respect to their physical properties, their optical properties, and their utility as a filler in papermaking.
  • my unique CSH products are suitable for multiple end uses, such as filler for value added papers, for commodity papers, for newsprint, paper coating applications, as well as for paints, rubber compositions, and other structural materials .
  • CSH's my unique multiple phase calcium silicate hydrates
  • my novel multi-phase mixture of foshagite and xonotlite, (Ca0 4 (Si0 3 ) (OH) 2 and C 6 Si 6 0 ⁇ 7 (OH) 2 , respectively) results in a unique mixture of calcium silicate hydrates which have a unique and distinct X-ray diffraction pattern.
  • CSH calcium silicate hydrates
  • Table le Strength property performance of handsheets containing 20% (interpolated) 5XPC 12 and pulp only.
  • This multi -phase (primarily Riversideite and Xonotlite) calcium silicate hydrate gave lower brightness value than that of Example 1. More significantly, this material gave a much lower water absorption (around 360% - 400%) as well.
  • This product compared to pulp only, gave substantially higher stiffness and sheet bulk.
  • this second pigment where Riversideite and Xonotlite are present
  • This second pigment (where Riversideite and Xonotlite are present) combination produced a much more open sheet, as shown by the low Gurley porosity numbers.
  • the optical properties like brightness, opacity and scattering coefficient of the sheet decreased. Comparing the performance of this second pigment (with predominantly Riversidite and Xonotlite present) with an alkaline filler, such as precipitated calcium carbonate, the sheet stiffness and bulk improved dramatically.
  • the optical properties (sheet opacity, sheet brightness, etc.) of the handsheets decreased, however.
  • the decreased optical properties of this new multiphase product were clearly due to the large particle size and irregular globular structure as seen in the S.E.M. pictures.
  • Table 2e Strength property performance of handsheets containing 20% (interpolated) 5XPC 27 and pulp only.
  • the reaction temperature was kept constant at 233 °C.
  • reaction parameters were all held constant, as in example 4, except for the CaO/Si0 2 mol ratio, which was raised to 1.8.
  • the hydrothermal reaction was carried out using the same cycle of heating and cooling as in the previous examples and the final product was again tested for key pigment properties.
  • the reaction conditions and key pigment properties are shown in Tables 4a and 4b respectively.
  • reaction time of 2 hours produced the highest brightness product.
  • the longer reaction time of 3 hours produced the greatest water absorption values, but at a lower brightness.
  • Example 14 Varying CaO - Si0 2 Slurry Concentration (XPC 140) In this reaction, all the reaction parameters were kept constant, as in example 12, except for the CaO + Si0 2 slurry concentration, which was raised to 0.8 lb/gallon. The product was tested as in example 3 and the reaction conditions and key pigment properties are shown in Tables 6a and 6b, respectively.
  • Table 9a Optical property performance of handsheets containing 20% (interpolated) TiSil and 20% (interpolated) PCC.
  • Table 9b Strength property performance of handsheets containing 20% (interpolated) of TiSil and 20% (interpolated) PCC.
  • Example 21 TiSil Brand CSH vs. Bulkite - XPC65
  • the pigment of my invention namely a calcium silicate hydrate complex (Foshagite - Xonotlite complex) was manufactured under the conditions given in Table 11a.
  • the pigment was tested for brightness, water absorption, Blaine, and pH. The results are given in Table lib.
  • This product was compared as a paper-making pigment with commercially available calcium silicate, (Trade name Bulkite) .
  • the graphical representation of the results are given in Figures 26-30.
  • the comparison of the two pigments, XPC-65 and Bulkite at 20% ash is given in Table lie.
  • the improvement over Bulkite at 20% ash (interpolated) is given in Table lid.
  • Handsheets utilizing titanium dioxide in fine paper were similarly formed, except that they required double the amount of retention aid as required by the other fillers. In addition, when Ti0 2 was added in conjunction with another filler, it was necessary to first add Ti0 2 , then add one dose of retention aid, and then add the filler and a second dose of retention aid.
  • Handsheets formed for newsprint testing were prepared in a similar method to the fine paper handsheets. However, different filler loading levels were utilized, and the newsprint sheets were usually loaded at 3%, 6%, and 9% filler. The handsheets were tested in accordance with TAPPI test method T-220, except that a 25.4mm sample was used and the tensile index calculations were recalculated accordingly. Handsheets were ashed in accordance with TAPPI test method T-211.
  • Figure 6 Figure 6 shows the S.E.M photograph at 2000 times magnification for StiSil Brand calcium silicate hydrate.
  • Figure 7 Figure 7 shows a graphical representation of the solubility of lime in water.
  • Figure 8 Figure 8 shows a graphical representation of the solubility of silica in water.
  • Figure 9 Figure 9 shows a graphical representation of a standard heating/cooling cycle for the reaction process .
  • Figure 18 shows a graphical representation of the brightness results from handsheets containing the TiSil brand calcium silicate hydrate and a PCC with 60lb/ton Ti0 2 mixture.
  • Figure 21 shows a graphical representation of the filler scattering coefficient results from handsheets containing the TiSil brand calcium silicate hydrate and a PCC with 60lb/ton Ti0 2 mixture .
  • Figure 22 shows a graphical representation of the sheet stiffness results from handsheets containing the TiSil brand calcium silicate hydrate and a PCC with 60lb/ton Ti0 2 mixture.
