Description
(54) СПОСОБ ИЗГОТОВЛЕНИЯ АСБЕСТОЦЕМЕНТНЫХ ИЗДЕЛИЙ(54) METHOD FOR MANUFACTURING ASBESTOSCEMENT PRODUCTS
За пределами этого диапазона значений прочность изделий на изгиб падает. Наиболее резко прочность изделий на изгиб падает при значетвси х облучени , выход щих за верхний предел,Beyond this range of values, bending strength of the products falls. The strength of bending products falls most sharply with irradiation values beyond the upper limit,
Пример осуществлени способа. Образец свежесформованного асбестоцементного наката, изготовленного на Воскресенском цементе, выдерживают при нормальной температуре и влажности воздуха более 80% в течение 2 ч . Затем образец облучают в камере сверхвысокочастотного генератора. ЧастотаAn example of the method. A sample of freshly formed asbestos cement reel, made on Voskresensk cement, is kept at a normal temperature and humidity of more than 80% for 2 hours. Then the sample is irradiated in the chamber of the microwave generator. Frequency
облучени составл ла 2 375 МГц, интенсивность потока энергии - ЮсмТ врем облучени - 25 сек. Дальнейший процесс твердени происходит при температуре 20 С и относительной влажности более 80%, Контроль образцов по пределу прочности на изгиб производили согласно ГСХГТу,the irradiation was 2 375 MHz, the intensity of the energy flux - UsmT - the irradiation time - 25 sec. The further process of hardening occurs at a temperature of 20 ° C and a relative humidity of more than 80%. The samples were tested for flexural strength according to the GSHGT,
Результаты испытаний приведены в табл, 1, (каждое значение предела прочности на изгиб - результат усреднени 5 испытаний) ,.The test results are given in Table 1, (each value of flexural strength is the result of averaging 5 tests),.

Из таблиц 1 и 2 видно, что образцы асбестоцемента, обработанные предло-; женным способом, набирают прочность вьпне конечной, требуемой ГОСТом, уже на 2-3 сутки.From tables 1 and 2 it can be seen that asbestos cement samples treated with the proposed; In a married way, they gain strength beyond the final required by GOST, already for 2-3 days.
При этом, после 28 суток твердени прочность образцов на изгиб достигает величины в 1,6 раза больше, чем требуетс ГОСТом.At the same time, after 28 days of hardening, the bending strength of the samples reaches a value 1.6 times greater than that required by GOST.
Использование предложенного способа дает возможность высвободить большие производственные площади, испольэу&лыв дл твердени асбестоцемента.Using the proposed method makes it possible to free up large production areas using & h to harden asbestos cement.
