摘要： Provided is a filter for inhibiting the degradation of edible oils, which can inhibit the degradation of an edible oil efficiently and easily without requiring the use of a filtering aid or the like and can also prevent the detachment of a degradation inhibiting agent to prevent the deterioration in the flavor of a food. The filter for inhibiting the degradation of edible oils comprises fibers (10) and at least one degradation inhibiting agent (13) selected from a carbonate, a silicate, a tartrate, an oxide, a hydroxide, an alginate and a phosphate.

摘要： The invention relates to a process for making paper, wherein a pulp suspension, which comprises mechanical pulp, is thickened in a dewatering device and is thereafter diluted with water and pumped to a storage tank, then diluted again and made in to paper. According to the invention, the pulp suspension is subjected to an acid - base treatment after the dewatering device. The pH of the suspension is first reduced with a strong acid by 0.5 -4 pH units to a pH between 4 and 6 and then the pH of the suspension is increased with a weak base by 0.5 -3 units to a pH below 8. The invention also relates to the use of an acid - base treatment in a process for making paper, wherein a pulp suspension, which has been thickened in a dewatering device, is subjected to an acid - base treatment for improving the process and/or the product. The invention provides improvements in the brightness of the pulp suspension and/or reduces the need for bleaching agent. The invention also decreases the dissolution of calcium carbonate filler in the process.

摘要： The invention relates to a method for producing paper with at least one fibrous material, a polymer, water and calcium oxide and/or calcium hydroxide, comprising the steps of disintegrating the fibrous material with water in a pulper for producing a fibrous material suspension and transferring the fibrous material suspension into a vat. The method is characterised in that in the disintegration of the fibrous material in the pulper calcium oxide and/or calcium hydroxide having a proportion of active substance between 0.1 kg per tonne of oven-dry fibrous material and 50 kg per tonne of fibrous material for setting of a pH value between 9 and 12 is added to the fibrous material suspension, and in the vat an acrylamide copolymer having a proportion of active substance between 0.1 kg per tonne of oven-dry fibrous material and 10 kg per tonne of fibrous material is added.
