First, to lay a good foundation earth manner. I began work in the first day, the responsible person put an English word printed with the notebook to me, and all of that some of the building materials on English words. The English word building materials is more complicated, hard to remember and more letters. For example: water rigid hydraulicity prescription formulation wire brush steel brush (construction) in the sand medium sand bonding glue strength infiltration of crystallization osmotic crystallizion workability workable anti-shock ability to force capability external walls of reinforced concrete wall exterior walling in proportion According Steel concrete playing to their ratio hair treatment Winding treatment slag cement Slag cement. building materials sector is a professional industrial collapse, which company's products will involve the chemical content, for example: PCCE - cyclohexyl - - methylene - Central has - Second carboxylate poly (cyclohexylene dimethylene cyclohexanedicar - boxylate) PCT poly (p-phthalic acid, Central Asia has been based - methyl-2) poly (cyclohexylene dimethylene terephthalate) PCTFE Poly Chlorotrifluoroethylene polychlorotrifluoroethylene PDAP Poly Phthaloyl acid poly propylene diene (diallyl phthalate). these words are very complex, if follow foreign businessmen to trade, then we have to introduce material names, attributes and prices. If, as the word chemistry, requires employees to remember their initials. However, in negotiating with foreign businessmen when employees can not speak-up laptop edge.
