Abstract:
(EN) Provided are a physical-chemical complex retardant for controlling the spontaneous combustion of low-rank coal, a preparation method therefor, and the use thereof. The complex retardant consists of a chelate and attapulgite, wherein the chelate is produced by means of the chelation of procyanidine and calcium chloride. The complex retardant has moisture absorbing and maintaining effects, and is capable of slowing the loss of moisture at low temperatures and producing isolating layers of oxides such as MgO and Al2O3 at high temperatures, wherein the isolating layers have a better stability and can block contact between a coal body and oxygen. Furthermore, the complex retardant can capture hydroxyl free radicals generated during a chain cycle reaction and destroy peroxide free radicals, and can also react with active structures in coal to produce stable structures such as ether linkage and hydrogen bond structures, thereby achieving persistent retardation for low-rank coal.
(FR) L'invention concerne un agent ignifuge complexe physique-chimique destiné à lutter contre la combustion spontanée de charbon de rang inférieur, son procédé de préparation et son utilisation. L'agent ignifuge complexe est constitué d'un chélate et d'attapulgite, le chélate étant produit au moyen de la chélation de la procyanidine et du chlorure de calcium. L'agent ignifuge complexe a des effets d'absorption et de maintien d'humidité, et est apte à ralentir la perte d'humidité à basses températures et à produire des couches isolantes d'oxydes tels que MgO et Al2O3 à des températures élevées, les couches isolantes présentant une meilleure stabilité et pouvant bloquer le contact entre un corps de charbon et de l'oxygène. En outre, l'agent ignifuge complexe peut capturer des radicaux libres hydroxyle générés pendant une réaction de cycle de chaîne et détruire des radicaux libres de peroxyde, et peut également réagir avec des structures actives dans du charbon pour produire des structures stables telles que des structures de liaison éther et de liaison hydrogène, ce qui permet d'obtenir un effet ignifuge persistant pour le charbon de rang inférieur.
(ZH) 提供防治低阶煤自燃的物理‐化学复合阻化剂及其制备和使用方法,该复合阻化剂由螯合物和凹凸棒土组成;其中,所述螯合物由原花青素和氯化钙经螯合作用生成。该复合阻化剂具有吸湿、保湿的作用,在低温下能减缓水分的散失,在高温下能产生稳定性较好的MgO、Al 2O 3等氧化物隔绝层,可以阻隔煤体与氧的接触;同时可以捕获链式循环反应过程中产生的羟基自由基,销毁过氧化物自由基,也可以与煤中的活性结构作用生成醚键、氢键等稳定的结构,实现对低阶煤的持久阻化。
