METHOD OF MEASURING THE CONTENT OF FIBRILLARY PARTICLES IN A PULP |
摘要 |
Measurement of the content of crill in pulp by means of different absorbency of the crill particles for light radiation of different wavelengths transilluminating the pulp. The crill content is determined by the difference in absorbency at a first wavelength having the same magnitude as the crill particles and a second longer wavelength between the first wavelength and the diameter of the pulp fibres. |
