The light feature points on a gypsum ceiling are first identified. The recessed point is formed by cutting out the gypsum boards. A hole of one by three feet is done the room corners. This is at intervals of five feet apart. The ceiling brandering is shaped to allow for the recess. The depth of the hole is half a foot. A gypsum hollow box is formed. It is one by three feet long. The electrical conduit is placed up into the recess point. Wiring is also done from the room control point.
Creates favorable soil EC: The more EC value of the soil is undesired for the crop growth. The high EC of soil are due to fertilizer application as well as by the weathering of soil minerals. Gypsum, being readily soluble, results in proper buffered solute concentration (EC) in soil to maintain soil in a flocculated state.

These become especially durable if they are manufactured not from raw materials, but from gypsum-rich manufacturing by-products.
Detergents, 5% Nitric Acid, 10% Ammonia, Ethanol, Oleic Acid, Bleach, 10% Hydrochloric Acid, Carbon Tetrachloride, Hydrogen Peroxide, and Port Wine will have no effect on the gypsum panel even if these chemicals come into contact with the panels for 24 hours. They can be easily washed with soap and water. 10% Citric Acid, Ketchup, 10% Sodium Hydroxide, Lemon juice, Coffee, Mayonnaise, Tea, Cooking oil, Milk, Trisodium Phosphate, Crayon, Mustard, and Vinegar will also have no effect on the gypsum board even when exposed to these chemicals for 24 hours. Pencil marks will leave a very light stain though. Acetone exposure for 24 hours then washed with soap and water will give the panels a shiny finish.
Manufacturers, in trying to find a way out of the situation, have invested in technological equipment which isn’t suitable for the Russian market, and this leads inevitably to an inability to set up normal manufacturing. Yet even so, there is excellent Russian-developed technology, including much which is available for instant application. The most important of these developments have received Russian and international recognition, particularly research carried out by MGSU into the development of water-resistant gypsum binders which outstrip rival products produced abroad. These include.
