Description
Работы по получению бариевых смесей дл ползчепи специальных цементов проводились в основном в направлении: применени алюминатов бари (при изготовлении огнеупорных цементов).Work on obtaining barium mixtures for crawling special cements was carried out mainly in the direction of: the use of barium aluminates (in the manufacture of refractory cements).
Однако в этом случае цементы не обладали водоустойчивостью, так как алюминаты бари растворимы в воде; частичной замены окиси кальци в портландцементиоп шихте окисью бари .However, in this case, the cements did not have water resistance, since barium aluminates are soluble in water; partial replacement of calcium oxide in portland cement mixture with barium oxide.
Указанные цементы также не были гидравличными. В некоторых случа х их гидравличности добивались добавкой гипса к готовому цементу.These cements were also not hydraulic. In some cases, their hydraulics were achieved by adding gypsum to the finished cement.
Насто щим изобретением установлено , что цементы специального назначени с высокоГг стойкостью против природных минерализованных вод, по сравнению с обычным и тампонажным портландцементом, могут быть ползчены из смеси гажп (глиногипсовой породы) и бари .The present invention has established that special purpose cements with high Hg resistance against natural saline waters, as compared with conventional and grouting Portland cement, can be crawled from a mixture of gage (clay gypsum rock) and bari.
Запасы гажи и бари в Азербайджане , Грузии, Армении, Туркмении и других районах СССР обеспечивают распространение нового бариево-сульфатного цемента. Этот цемент обладает повышенным удельным весом, что делает его использовани перспективным дл тампонажа скважин, в рентгенотехнике и других отрасл х строительства .The stocks of drywall and bari in Azerbaijan, Georgia, Armenia, Turkmenistan and other regions of the USSR ensure the distribution of new barium-sulphate cement. This cement has an increased specific gravity, which makes it promising for cementing wells, in X-ray technology and other construction sites.
Дл получени цемента смесь гажп и барп в отнон1ерги х от 1:0,5 до 1:1,25 при добавке около 5% уг .т от веса сульфатов обжигаетс при 1100-1300° вслабоокислительноГ среде. Обожженна смесь измельчаетс в паровой мельнице и просеиваетс па сите № 90 (4900 отвс г.To obtain a cement, a mixture of gajp and barn in independent x from 1: 0.5 to 1: 1.25 with an addition of about 5% carbon by weight of sulphate is calcined at 1100–1300 ° in oxidizing medium. The burned mixture is crushed in a steam mill and sieved with sieve No. 90 (4900 SFA,
Добавка 0.25 о сульфитно-спиртовой барды к бариево-сульфатному пементу значительно удлин ет схватывани .The addition of 0.25 o of sulphite-alcohol stillage to the barium sulphate cement significantly extends the setting.
П р е д м е т и з о б р е т е н и PRIORITY AREA
Способ получени бариево-сульфатного цемента на основе гажп с добавками при последующем обжиге и измельчении, отличаюнд и и с тем, что, с целью нолучени в жущего, обладаюп1его повышенным удельным весом и стойкостью в агрессивных средах, в качестве компонентов сырьевой смеси берут гажу и барий в соотношени х от 1:0,5 до 1:1,25и облчигают при 1100-1300°.The method of obtaining barium-sulphate cement on the basis of gajp with additives during subsequent calcination and grinding, differs from and with the fact that, in order to obtain a binder, it has an increased specific weight and stability in aggressive media, as components of the raw mix take drywall and barium in ratios from 1: 0.5 to 1: 1.25 and are measured at 1100-1300 °.
