Description
Способ изготовлени гиисовых облицовочных плит размером, например, ЮОХ XI00X10 мм, состоит в следующем.A method of manufacturing gyate facing tiles with a size of, for example, UOH XI00X10 mm, is as follows.
Приготавливают смесь гипса с водой нормальпой густоты (,52) в количестве 325 г и укладывают в герметичную прессформу с предусмотренными в ней фильтрами из стекловолокна и каналами дл удалени влаги. На нресс-форму с гинсовой смесью подают давление со скоростью 8 МПа/мин до величины 10 МПа. Под этим давлением выдерживают форму со смесью в течение 4,5 мин, затем снимают давление и изделие освобождают от формы.A mixture of gypsum with water of normal thickness (, 52) in an amount of 325 g is prepared and placed in a pressurized mold with glass fiber filters and channels to remove moisture. Pressure is fed at a rate of 8 MPa / min to a value of 10 MPa to a nitrogen form with a hens mix. Under this pressure, keep the shape with the mixture for 4.5 minutes, then relieve pressure and the product is released from the form.
Плиты, полученные таким способом, через 24 ч после распалубки при нормальновлажностном хранении или через 4-5 ч после подсушки нри 45-50°С имеют прочность на сжатие 500-650 кг/см, коэффициент водостойкости 0,9-0,95.The plates obtained in this way, 24 hours after demolding during normal humidity storage or 4-5 hours after drying at 45–50 ° C, have a compressive strength of 500–650 kg / cm, a water resistance coefficient of 0.9–0.95.
