The amount of paint used improves with the improvement of housing conditions. Many households paint a layer of colored paint on the white powder wall. Before painting, the required paint should be estimated. Otherwise, it will cause waste, and if it is less, it will not be enough. Moreover, if the water is added again, the color is difficult to be consistent. A simple calculation method is introduced. Dividing the room area by 4, the height of the painted wall is multiplied by 10 and 4, and the sum of the two is the number of kilograms of paint required. For example, the room area is 20 square meters and the wall height is 1.6 meters. 1.2 m wall skirt), then (20 ÷ 4) + (16 ÷ 4) = 9, that is, 9 kg of paint can paint the wall twice.
The amount of floor tiles. For example, the size of the floor tile is 30.5 cm × 30.5 cm, that is, the floor area of ​​1 square meter per floor requires about 10 pieces of floor tiles, and then multiplied by the number of square meters of the room, that is, the number of blocks used. Since the edge of the floor often uses the cut floor tiles, it is best to draw a sketch according to the floor size of the room. When selecting the pattern, determine how many blocks are used for the deep and shallow floor tiles, and accurately calculate how many blocks to use. There are many types of adhesives used for whole floor tiles and floor tiles. Most of the glues used for bonding rubber and plastic can be used. Currently, there are 401 glues, 4116 glues, floor glues, etc., usually 1 kg. It can paste 4~6 square meters of floor tiles. If the amount is too much, the glue will be squeezed out from the gap of the floor to contaminate the ground in the future. It is difficult to clean. If the glue is less, the floor tiles will be off the ground after drying. .
Ethylene amines refers to the acyclic ethylenediamine polymer products, as an important fine chemical intermediates, ethylene amines in organic synthesis, medicine, dye, pesticide, chemical fertilizer, rubber plastic additives, organic solvents and Epoxy Resin Curing Agent, and other fields has been widely used. which become to be one of the fine petrochemical intermediates for the development of China. Ethylenediamine (EDA) is a very important intermediate, mainly used to produce EDTA(chelating agent) and TAEDA(bleach activator), can also be used to produce Organic Dye, Dye-fixing Agent, coating, pesticide, etc. Piperazine can be used to produce anhydrous piperazine, n-methyl piperazine, n-ethyl piperazine, pharmaceutical intermediates, fluperacid, halogen free flame retardant, triethylene diamine. Piperazine has been exported to India and Japan.
