Description

(54) СПОСОБ ИЗГОТОВЛЕНИЯ ПОРИСТОГО ЛИСТА(54) METHOD OF MANUFACTURING A POROUS SHEET

смесь нанос т на подложку литьем через щель бункера. После сушки и удалени  растворител  толщина листа на подложке 40-50 мкм. Механическое уплотнение полученного листа на подложке производ т в валках с посто нным усилием с обжатием по толщине 40- 50%. Спекание листа на подложке осуществл ют -при 1000-1050° С в течение 30 мин в атмосфере влажного водорода.the mixture is applied to the substrate by casting through the slot of the hopper. After drying and removing the solvent, the thickness of the sheet on the substrate is 40-50 microns. Mechanical compaction of the obtained sheet on the substrate is carried out in rolls with a constant force with a compression in the thickness of 40-50%. Sintering the sheet on the substrate is carried out at from 1000 to 1050 ° C for 30 minutes in a humid hydrogen atmosphere.

Спеченный пористый никелевый лист свободно отдел етс  от .подложки и имеет следующие характеристики: толщина 20-25 мкм; пористость 50%; прочность на разрыв 6- 10 кг/мм ; количество перегибов на 180° без разрушени  на радиусе 0,3 мл1 10-15; удельное электрическое сопротивление (0,98-1,2) х Х10-5 Ом см.The sintered porous nickel sheet is free to separate from the substrate and has the following characteristics: thickness 20-25 microns; porosity 50%; tensile strength 6–10 kg / mm; the number of kinks at 180 ° without destroying a radius of 0.3 ml1 10-15; electrical resistivity (0.98-1.2) x 10-5 Ohm cm.

Предложенный способ может быть использован в электротехнической промышленности и позвол ет значительно уменьшить габариты аккумул торов.The proposed method can be used in the electrical industry and can significantly reduce the size of batteries.
