Description
Technical field
The present invention relates to fine hair property values figureofmerit checkout equipment, be particularly related to the fluffy performance of a kind of Time of Fluff Slurry and water absorbing properties automatic analyzer, measure for the fluffy performance of Time of Fluff Slurry and the water absorbing properties of the absorbent time of measuring the fine hair sample, water absorbing capacity, fluffy height, fluffy degree performance.
Background technology
Time of Fluff Slurry is the special senior water absorptivity paper pulp of processing of a kind of process, the raw material of this kind slurry is finished product chemical pulp or mechanical pulp, after adopting physical method to make its suede fluffing, have splendid water absorptivity and fluffy degree, the most suitable in order to make such as the health such as paper nappy, sanltary towel, hospital bed lining paper water absorptivity product and other disposable Time of Fluff Slurry product.
Periodical " Tappi Journal " Vol.66 of U.S. pulping and paper-making association (11), 45 (1983); Northern Europe pulping and paper-making association criterion SCAN-C33:80 is described and stipulates the property values figureofmerit specific volume of Time of Fluff Slurry and absorptive detection principle and detection method.
Its property values figureofmerit of purposes according to Time of Fluff Slurry mainly comprises: the indexs such as the fluffy performance of Time of Fluff Slurry, absorption speed, water-intake capacity, technical literature comprises the scientific payoffs G040-2003 of State Administration for Quality Supervision and Inspection and Quarantine " research of Time of Fluff Slurry capability and performance and detection method thereof and checkout equipment ".
Time of Fluff Slurry capability and performance checkout equipment generally includes: fluff pulp board disperser, sample former, fluffy performance and bibliometer series is totally three equipment.
Decollator is the instrument that flossy pulp-board is dispersed into the fine hair of fiber condition, in dispersion, should guarantee that flossy pulp-board disperses fully, make pulpboard be dispersed into the single fiber state as far as possible and avoid occurring not scattered lodicule, make again simultaneously fibre breakage and broken few, to guarantee the character of fibre length and fine hair.
Absorption of water and fluffy degree are the topmost performance index of Time of Fluff Slurry, and the instrument of measuring this performance comprises two parts: 1, sample former.Sample former is the cylindric sample that the fine hair that will disperse is prepared into 3g diameter 50mm, and for the usefulness of measuring water absorptivity and fluffy degree, the fiber in the sample requires to be evenly distributed consistent.Time of Fluff Slurry after the dispersion is inhaled into from entrance, disperses to descend in tapered dispersion pipe spiral, forms a slurry pad sample and be used for experiment in forming tube.2, measure fluffy performance and the bibliometer of absorbent time, water absorbing capacity, fluffy height, fluffy degree.
After decollator was dispersed into the fine hair of fiber condition to flossy pulp-board, the slurry pad sample that is formed by sample former offered fluffy height, fluffy degree, absorption speed and the water absorbing capacity that fluffy performance and bibliometer are measured the fine hair sample; Though at present the fine hair performance index and the detection method that detect of various countries is not quite similar, the fluffy degree of fine hair and absorptive detection then generally believed be absolutely necessary, there is no satisfactory Time of Fluff Slurry property values figureofmerit checkout equipment and China is domestic at present.Therefore, the development of satisfactory fluffy performance and bibliometer also is one of main contents of Time of Fluff Slurry property values figureofmerit checkout equipment.
In the commodity inspection technical field, existing fluffy performance and water absorbing properties sensing equipment all adopt mechanical structured member to consist of, the mensuration process is fully by manually-operated and control, because tester's individual level difference, so that the consistance of the fluffy performance of Time of Fluff Slurry and water absorbing properties measurement result is poor, there is error in accuracy for the detection architecture of the fluffy performance of Time of Fluff Slurry, absorption speed, water-intake capacity index, be unfavorable for carrying out smoothly of commodity inspection work, therefore, need to by checkout equipment is carried out technological improvement, improve automaticity and measuring accuracy.
