Description
Асбестоцементные издели с- транспортера твердени поступают в увлажнитель листов, заполненный дистиллерной жидкостью, где и подвергаютс кратковременному насыцению в течение 30 мин. Температура дистиллерной жидкости в увлажнителе 40-42®С. Состав солевой дистиллерной жидкости следующий, г/л«Asbestos-cement products from the hardening conveyor are fed to a sheet humidifier filled with distiller liquid, where they are subjected to short-term saturation for 30 minutes. Distiller fluid temperature in a 40-42®С humidifier. The composition of the salt distiller fluid is the following, g / l "
CaClg 60-70CaClg 60-70
CaSO .0,67CaSO .0,67
Щелочность qo ОЯ - 0,48 (в гом числе и Са (ОН) )Alkalinity qo ОЯ - 0.48 (among the whole, and Ca (OH))

NaCl - 31NaCl - 31
После кратковременного насьЕцени в дистиллерной жидкости в течение 30 мин асбесгоцементные издели стопируют и отправл ют на склад твердени .After a short period of time, the asbestos-cement products are stopped in a distiller fluid for 30 minutes and sent to a hardening warehouse.
П р и м е р 2. Асбестоцементные издели после пропарки подвергали обработке по режиму, описанному в примере 1.PRI mme R 2. Asbestos-cement products after steaming were subjected to treatment according to the mode described in example 1.
При этом солевой состав дистиллерной жидкости был следующий,г/л:While the salt composition of the distiller fluid was the following, g / l:

Щелочность по ОН - 0,96.Alkalinity on OH is 0.96.
Физико-механические показатели асбестоцементных изделий, изготовленных таким способом, следующие:Physico-mechanical properties of asbestos-cement products manufactured in this way are as follows:
Объемна масса 162-173 кг/мBulk weight 162-173 kg / m
Предел прочности при изгибеFlexural Strength
(через 28 суток)163-220 кг/см(after 28 days) 163-220 kg / cm
(в зависимости от концентрации хлористого кальци ).(depending on the concentration of calcium chloride).
Применение предпагаемого способа интенейфикаШ1и твердени асбестоцементных изделий обеспечивает более высокий прирост механической гфочности и объемной массы,при этом сокращаетс продолжительность твердени на двое суток,а в течение п ти суток достигаетс требуема механическа прочность,The use of the intended method of indenication and hardening of asbestos-cement products provides a higher increase in mechanical viscosity and bulk density, while reducing the duration of hardening by two days, and within five days the required mechanical strength is achieved.
Кроме того, сокращаетс на 30% площадь склада твердени .In addition, the storage area is reduced by 30%.
