Abstract

Postupak za proizvodnju termoizolacionog materijala otpomog na visokim temperaturama. gde je vodena suspenzija Ca(OH)2, koja sadrži min. 70% mas. slobodnog CaO i mlevenog kvarca, sa veličinom čestica ispod 63 Вµm i koji sadrži min. 96% mas. SiO2, pri čemu je molski odnos CaO/SiO2 0,83 - 1 i odnos voda - suva supstanca 3 - 4, sa dodatim organskim i neorganskim vlaknima u količini 2 - 7% mas. računato na suvu supstancu i stabilizatorom sredine u količini 0,4 - 0,5% mas., naznačen time, što je mleveni kvarc prethodno termički obrađen na temperaturi od 1000В°C, što su vlakna od sulfatne četinarske beljene celuloze debljine oko 3 Вµm, dužine oko 15 Вµm i dužine kidanja preko 8000 m i/ili sintetička poliesterska vlakna debljine 10 - 12 Вµm i dužine do 8 mm, a stabilizator sredine površinski aktivna materija alkil fenol poliglikol etar i što se tako dobijena suspenzija podvrgava hidrotermalnoj obradi u autoklavu, prvo pritisku zasićene vodene pare od 11,5 - 12,5 bara u vremenu od 10 - 15 sati, a zatim temperaturi pregrejane vodene pare od 190 - 210В°C u vremenu od 5 - 9 sati, gde ukupno vreme hidrotermalne obrade suspenzije u autoklavu iznosi 15 - 24 sata, nakon čega se očvrsli materijal vadi iz autoklava i suši do određenog masenog procenta vlažnosti. Prijava sadrži još 1 patentni zahtev. Process for the production of thermal insulation material with the help of high temperatures. wherein the aqueous suspension is Ca (OH) 2, containing min. 70% of the mass. of free CaO and ground quartz, with a particle size below 63 Vµm and containing min. 96% of the mass. SiO2, where the molar ratio of CaO / SiO2 is 0.83 - 1 and the ratio of water - dry matter is 3 - 4, with added organic and inorganic fibers in the amount of 2 - 7% wt. calculated on the dry substance and the medium stabilizer in the amount of 0.4 - 0.5% by weight, characterized in that the ground quartz was previously heat-treated at a temperature of 1000V ° C, which are fibers of sulfate coniferous bleached cellulose with a thickness of about 3 Vµm, length of about 15 Vµm and tear length over 8000 m and / or synthetic polyester fibers 10 - 12 Vµm thick and up to 8 mm long, and the stabilizer medium surfactant alkyl phenol polyglycol ether and thus the resulting suspension is subjected to hydrothermal treatment in an autoclave, first pressure saturated water vapor of 11.5 - 12.5 bar in a time of 10 - 15 hours, and then the temperature of superheated water vapor of 190 - 210V ° C in a time of 5 - 9 hours, where the total time of hydrothermal treatment of the suspension in the autoclave is 15 - 24 hours, after which the hardened material is removed from the autoclave and dried to a certain percentage by mass of moisture. The application contains 1 more patent application.
