Description
Изобретение касаетс способа обработки ломкого хризотилового асбеста дл производства фильтрующих картонов.This invention relates to a process for the treatment of brittle chrysotile asbestos for the production of filter boards.
Способ обработки состоит в том, что асбест подвергают кип чению в течение 1 час в 0,2-0,25%-ном растворе технической сол ной кислоты из расчета на 1 кг асбеста 15 л раствора. После кип чени асбест отмывают холодной водой от остатков кислоты в сетчатых сцежах или во вращающихс сетчатых цилиндрах до нейтральной реакции по метилоранжу . Затем расщепл ют на топкие элементарные волокна путем диспергировапи асбеста в водной среде при концентрации волокна 0,5-1% в вертикальной лопастной мешалке при скорост х вращени лопастей 900-1000 об/мин в течение 40-50 минут.The treatment method is that asbestos is boiled for 1 hour in a 0.2–0.25% solution of technical hydrochloric acid per 1 kg of asbestos 15 liters of solution. After boiling, asbestos is washed with cold water from acid residues in sieve sections or in rotating sieve cylinders until neutral according to methyl orange. Then, it is split into friable elementary fibers by dispersing asbestos in an aqueous medium at a fiber concentration of 0.5-1% in a vertical paddle mixer at speeds of rotation of the blades of 900-1000 rpm for 40-50 minutes.
Такой способ обработки асбеста обеспечивает повышение качества фильтрующих картонов, по сравнению с картонами из ломкого асбеста, приготовленными известными ранее способами.This method of asbestos treatment provides an increase in the quality of filter cartons, as compared with brittle asbestos cartons prepared by previously known methods.
Предмет изобретени Subject invention
Способ обработки ломкого хризотилового асбеста, например, дл производства фильтрующих картонов, отличающийс тем, что, с целью повышени фильтрующих свойств, асбест подвергают кип чению в течение 1 час в 0,2-0,25%-ном растворе технической сол ной кислоты из расчета на I кг асбеста 15 л раствора, затем асбест отмывают и подвергают расщеплению на тонкие элементарные волокна в вертикальной лопастной мешалке.A method of treating brittle chrysotile asbestos, for example, for the production of filter cartons, characterized in that, in order to increase the filtering properties, asbestos is boiled for 1 hour in a 0.2-0.25% technical hydrochloric acid solution based on on I kg of asbestos 15 liters of solution, then asbestos is washed and subjected to splitting into fine elementary fibers in a vertical paddle mixer.
