Abstract

La présente invention concerne un procédé pour préparer des matériaux de source de chaleur carbonés, comprenant les étapes suivantes : 1) la combinaison d'alginate de sodium ou d'alginate d'ammonium ou d'alginate de potassium avec de la poudre de carbone et de l'eau, et leur agitation pour gélification, le rapport en masse entre l'alginate de sodium ou l'alginate d'ammonium ou l'alginate de potassium et la poudre de carbone étant de 1:5 à 1:45 ; 2) la pression et le formage de la gelée, et la mise de la gelée en contact total avec une solution d'agent de durcissement qui peut modifier l'alginate et séparer les matières solides, de sorte que la gelée d'alginate formée sépare le condensat ; et 3) le rinçage et le séchage du composé de carbone durci et formé, de manière à permettre que la teneur en eau atteigne 10 à 20 %, de sorte que des matériaux de source de chaleur carbonés en forme de plaque utilisés pour une cigarette soient obtenus. Le procédé selon la présente invention est simple et a un cycle de production court. Les matériaux de source de chaleur carbonés préparés ne nécessitent pas d'être tassés au moyen de fibres de verre, ce qui élimine les dommages causés par l'inhalation de fibres de verre par des personnes. Les matériaux de source de chaleur carbonés ainsi préparés sont applicables à une production continue en masse dans l'industrie. De plus, la présente invention peut produire des matériaux de source de chaleur carbonés filamenteux et en forme de plaque, qui sont plus aisément allumés qu'une tige de carbone formée par pressage.
