Description

Производство строительных материалов , основанное на применении слабо-обожженного доломита, затвор емого концентрированными растворами хлористого магни  или сернокислого магни , требует точного обжига, при котором в доломите должен разлагатьс  на окись магни  и углекислоту только углекислый магний, а углекислый кальций при этом не должен затрагиватьс . Так как последнего в доломите больше половины, то обычно некотора  часть его все же разлагаетс  и дает в обожженном доломите примесь оки1.и кальци , котора  сильно вредит процессу твердени  доломитового в жущего .The production of building materials based on the use of weakly baked dolomite, shuttered with concentrated solutions of magnesium chloride or magnesium sulphate, requires precise calcination, in which only carbon dioxide magnesium should decompose to magnesium oxide and carbon dioxide, and carbon dioxide should not be affected. Since the latter is more than half in dolomite, usually a certain part of it nevertheless decomposes and gives an admixture of calcium and calcium in the burnt dolomite, which greatly damages the process of dolomite hardening.

В цел х устранени  указанного дефекта примен ют обработку массы, содержащей магнезию с наполнител ми , влажной углекислотой, причем наличие примеси извести в этом случае не  вл етс  вредным. В предлагаемом способе, в котором исходным продуктом  вл етс  каустический доломит, замешиваемый с органическими наполнител ми на воде и затем также подвергаемый обработке углекислым газом в дырчатых формах, прибавл ют каталитические добавки, сокращающие врем  затвердевани In order to eliminate this defect, the treatment of the mass containing magnesia with fillers with wet carbon dioxide is used, and the presence of a lime impurity in this case is not harmful. In the inventive method, in which the starting product is caustic dolomite mixed with organic fillers in water and then also subjected to treatment with carbon dioxide in perforated forms, catalytic additives are added, which shorten the solidification time.

Дл  изготовлени  строительных плит, досок, блоков и прочих изделий древесна  стружка, опилки, костра, кенаф, костра конопли, камыш и тому подобные органические материалы смешиваютс  с водой и слабо-обожженным доломитом , затем формуютс  в специальных формах; в случае изготовлени  стружечных плит последние по широ кой плоскости зажимаютс  между двум  щитами, имеющими отверсти , а в случае изготовлени  блоков- непосрегственно после формовки издели  зп г жаютс  в автоклав или камеры, в которые затем под давлением нагнетаютс  газы, содержащие углекислоту.

As such additives, caustic or carbonic salts of potassium and or wood ash are used. . For the manufacture of building boards, boards, blocks and other products, wood chips, sawdust, campfire, kenaf, hemp campfire, reed and similar organic materials are mixed with water and weakly burnt dolomite, then molded into special forms; in the case of chipboard manufacturing, the latter are clamped over a wide plane between two shields with openings, and in the case of block manufacturing, directly after molding the product zp, they are pressed into an autoclave or chamber, into which carbon dioxide-containing gases are then pressurized. Upon reaching solidification of the products, they are unloaded from autoclaves or chambers, freed from molds or shields, and then dried.
