Description
Известны высокотемпературные цементы на основе алюмофосфатной св зки. Однако применение их ограничено, так как они не могут быть использованы в качестве токопровод щего материала.High temperature aluminophosphate binder cements are known. However, their application is limited, since they cannot be used as a conductive material.
Цель насто ндего изобретени -обеспечение цементу токопровод щих свойств. Достигаетс это тем, что он содержит в своем составе следующие компоненты в вес. %:The purpose of the present invention is to provide cement with conductive properties. This is achieved by the fact that it contains the following components in its weight. %:
мелкодисперсный графитfine graphite
(фракци 10-20)17,0-17,6(fraction 10-20) 17.0-17.6
алюмофосфатную св зкуaluminophosphate bond
30%-ной нейтрализации13,6-1430% neutralization13,6-14
окись алюмини 5-микронную,5 micron alumina,
прокаленную при 1000°Сcalcined at 1000 ° C
В воздушной среде17,0-17,6In the air 17.0-17.6
дистиллированную воду52,4-50,8.distilled water 52,4-50,8.
Сопротивление такого высокотемпературного токопровод щего цемента равно приблизительно 1,5 ом- см.The resistance of such high-temperature conductive cement is approximately 1.5 ohm-cm.
При изменении соотношени наполнителей графита и окиси алюмини в 100 раз сопротивление возрастает в 100000.When the ratio of the fillers of graphite and alumina is changed by 100 times, the resistance increases by 100,000.
Указанный состав благодар своим составным част м может быть использован в электровакуумной промышленности дл склеивани внутривакуумных деталей, так как он не выдел ет нри откачке больших количеств газообразных продуктов.This composition, due to its constituent parts, can be used in the electrovacuum industry for gluing intravacuum parts, since it does not emit large quantities of gaseous products when pumping.
