Известь, затем эмульсию ГКЖ-94 ввд т в воду затворени . После этого гипс .и ускоритель схватывани - дву водный гипс перемешивают с воднымLime, then an emulsion of NGL-94 vbd t into the mixing water. After that, the gypsum. And the accelerator setting - two-water gypsum is mixed with water.
iJpacTBODOM извести и эмульсии ГКЖ-94 стандартный методом. Из полученной смеси формуют издели . Отфо ллован- ные издели выдерживают в естественных услови х при температуре 293298 К на воздухе с относительной влажностью 60-80% до установлени равновесного влагосодержани . Затем определ ют гидрофобность изделий по исследованию краевого угла, смачивани его поверхности.iJpacTBODOM lime and emulsion GKZH-94 standard method. From the mixture obtained molded product. Unfolded products are kept under natural conditions at a temperature of 293298 K in air with a relative humidity of 60-80% until the equilibrium moisture content is established. Then, the hydrophobicity of the products is determined by examining the contact angle, wetting its surface.
Результаты исследовани краевого угла смачивани гипсовых образцов полученных на основе предлагаемо композиции ) по табл.1 и на основе известной смеси представлены в табл.2 и 3.The results of the study of the wetting angle of gypsum samples obtained on the basis of the proposed composition) according to Table 1 and based on the known mixture are presented in Tables 2 and 3.
Как видно из табл.3 гидрофобность образцов на основе предлагаемой смеси превышает гидрофобность образцов на Основе смеси прототипа на 20-24%. As can be seen from table 3, the hydrophobicity of the samples on the basis of the proposed mixture exceeds the hydrophobicity of the samples on the basis of the mixture of the prototype by 20-24%.
Проведенные испытани подтвердили преимущества предлагаемого Iэoбретени -«повышение гидрофобности.The tests that were carried out confirmed the advantages of the proposed i-acquisition - "increased hydrophobicity.
