Description
Известны формы дл изготовлени изделий из бетона, пенобетона и пеноизвести и т. п. масе с пропариванием их под давлением в таких формах и использованием дл этой цели пара, выдел ющегос из пропариваемой массы.Forms are known for the manufacture of products from concrete, foam concrete, and foam, etc., to masa with steaming them under pressure in such forms and using steam extracted from the steaming mass for this purpose.
Особенность описываемой формы заключаетс в том, что она выполнена в виде герметически закрывающегос термоизолированного щика, снабженного нагревательным устройством (например электронагревател ми ).A feature of the described form is that it is made in the form of a hermetically sealed insulated box equipped with a heating device (for example, electric heaters).
На фиг. 1 и 2 изображены продольный и поперечный разрезы jai;ной формы дл изготовлени высокопрочной теплоизол ции теплофикационных труб.FIG. Figures 1 and 2 depict longitudinal and transverse sections of jai; s form for the manufacture of high-strength thermal insulation of heat pipes.
Цилиндрические формы изготовл ютс из листовой стали и состо т из двух разъемных частей - верхней / и нижней 2. В верхней части / имеютс отверсти 3 дл выпуска воздуха при заполнении формы материалом и отверсти 4 дл заливки материала 5. Внещн поверхност, форм покрыта слоем легкой теплоизол ции 6. Внутри формы помещаетс труба 7 с проложенными в ней нагревател ми 8. Концы трубы закрываютс съемными теплоизол ционными крышками 9, снабжеюгымн фланцами 10, плотно прилегающими к форме.Cylindrical forms are made of sheet steel and consist of two detachable parts - upper / lower 2. In the upper part / there are openings 3 for air release when filling the mold with material and openings 4 for pouring material 5. The outer surfaces of the molds are covered with a layer of light heat insulations 6. Inside the mold, a pipe 7 is placed with heaters 8 laid in it. The ends of the pipe are closed with removable heat insulating covers 9, equipped with an iron flange 10, tightly adjacent to the form.
Материал заливаетс в формы под давлением 1,5-2 м вод ного столба.The material is poured into molds at a pressure of 1.5-2 m of water.
Воздущные и заливочные отверсти в формах плотно закрываютс . После включени тока температура внутри трубы поднимаетс до и поддерживаетс на этом уровне в течение 12 час.Air and priming holes in the molds tightly closed. After switching on the current, the temperature inside the pipe rises to and is maintained at this level for 12 hours.
За этот период происходит процесс схватывани цемента.During this period, the cement setting process takes place.
После этого температура в трубе постепенно, в течение 8-Ш час, поднимаетс до 180°С и поддерживаетс на этом уровне не менее 6 час. Затем температуру понижают, причем понижение производитс также за 6-8 час. Дл ускорени снижени температуры летом с концов труб крыщки снимаютс .After that, the temperature in the pipe gradually, over an 8 hour period, rises to 180 ° C and is maintained at this level for at least 6 hours. Then the temperature is lowered, and a decrease is also carried out in 6-8 hours. In order to accelerate the decrease in temperature in summer, the ends of the tubes are removed.
