    摘要: Silica-calcium carbonate composite particles, characterized in that they are produced by a method wherein, in a carbonation step of forming calcium carbonate, typically a step of introducing a mixed gas of carbon dioxide and air into a calcium hydroxide slurry with stirring to carry out a carbonization reaction, a synthetic silica such as colloidal silica is added in a period after the start of the carbonization and before carbonization percentage reaches 95 %, the mixed gas is continuously introduced thereafter to continue the carbonization, and the carbonization is stopped when the pH of the slurry reaches 7; a paper having said particles filled therein; and the above method. Said composite particles have both of the characteristics inherent in a synthetic silica and in calcium carbonate, without detriment to the characteristics.

    摘要: A method for treating solid-containing material contained in or produced from waste paper or an effluent from a plant for treating paper or paper waste, the solid-containing material including organic material and inorganic particulate material, the method comprising subjecting the solid-containing material to a heat treatment which incinerates the organic material present and forms a calcined product from the inorganic particulate material present, and characterised in that the calcined product is formed into an aqueous suspension which includes a salt-forming cationic species and a reagent which contains or generates a salt-forming anionic species is added to the suspension to form an insoluble salt precipitate therein. The solid-containing material treated by the method may include calcium carbonate, whereby calcium oxide is formed in the heat treatment by decomposition of at least part of the calcium carbonate present, and wherein the calcium oxide is converted to calcium hydroxide when the calcined product is formed into an aqueous suspension, the said salt-forming cationic species comprising calcium ions derived from the calcium hydroxide and wherein the said reagent comprising a salt-forming anionic species comprises carbon dioxide whereby the precipitate comprises calcium carbonate.

    摘要: A process for forming a moulded paper product which is degradable in a moisture active landfill is disclosed. The process involves providing a paper pulped paper feedstock, moulding the feedstock to produce a shaped product, drying the shaped product, applying a coating composition on to at least one surface of the shaped product, curing the coating composition and, optionally, hot pressing the resulting product to form a moulded paper product. When the moulded paper product is coated utilizing a particularly preferred coating composition described herein, which is comprised of a cement, at least one of a clay and a sulphate, an aqueous emulsion polymer, and preferably, at least one of an organic acid and a wax, it is readily degradable in a moisture active landfill.
