    摘要： A building material product comprising a cementitious binder, an aggregate and cellulose reinforcing fibers wherein the cellulose reinforcing fibers have been treated with cationic or nonionic oil. The resulting fiber when included in a fiber cement composite results in improved deflection of the composite at peak loading as well as improved impact strength while maintaining overall board strength.

    摘要： A method of making bleached mechanical pulps is disclosed for pulping mills having a primary and a secondary refiner. A first step is to provide cellulosic materials, such as wood chips to refine into the pulp; the wood chips have an initial brightness level. A second step is to provide a bleaching liquor to the refining system of the pulp mill, wherein the liquor comprises an amount of hydrogen peroxide and an amount of alkali having greater than 0% to 100% magnesium hydroxide or soda ash or a combination thereof. A third step is to hold the pulp with the bleaching liquor at a temperature in the range of about 85° to about 160° C. and for about 2 to about 180 minutes. The components of the bleach liquor can be added at the first refiner or interstage between refiners.
