At the time of completion, you will often find that the total amount of the project will be much more than the amount of the contract, and some of them can reach 20%. Why?

1 First of all, if you review yourself, are you not able to resist the foreman's softening and hard work, and you have also added a lot of renovation projects? For instance, outside the contract, have you made a shoe?
2 Is it a lot of things that should have been used by decoration companies to buy things and eventually become your own money?
3 If you look at the contract, is there a place for double counting, for example, if your paint is bought by yourself, but are you still paying the paint money to the decoration company on a budget?
4 Have you measured the area of ​​all construction projects carefully? You know, even if you put the price down before the decoration, the designer has a way to quietly add money back to you in the budget. The way is to work on the amount of work.

Thiocyanate (also known as rhodanide) is the anion [SCN]−. It is the conjugate base of thiocyanic acid. Common derivatives include the colourless salts Potassium Thiocyanate and Sodium Thiocyanate. Organic compounds containing the functional group SCN are also called thiocyanates. Mercury(II) thiocyanate was formerly used in pyrotechnics.
Thiocyanate is analogous to the cyanate ion, [OCN]−, wherein oxygen is replaced by sulfur. [SCN]− is one of the pseudohalides, due to the similarity of its reactions to that of halide ions. Thiocyanate used to be known as rhodanide (from a Greek word for rose) because of the red colour of its complexes with iron. Thiocyanate is produced by the reaction of elemental sulfur or thiosulfate with cyanide
Thiocyanate[4] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase.[5][6][7] Thus the complete absence of thiocyanate[8] or reduced thiocyanate[9] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.[10][11]
Thiocyanate is a potent competitive inhibitor of the thyroid sodium-iodide symporter.[12] Iodine is an essential component of thyroxine. Since thiocyanates will decrease iodide transport into the thyroid follicular cell, they will decrease the amount of thyroxine produced by the thyroid gland. As such, foodstuffs containing thiocyanate are best avoided by Iodide deficient hypothyroid patients.[13]
In the early 20th century, thiocyanate was used in the treatment of hypertension, but it is no longer used because of associated toxicity.[14] Sodium nitroprusside, a metabolite of which is thiocyanate, is however still used for the treatment of a hypertensive emergency. Rhodanese catalyzes the reaction of sodium nitroprusside with thiosulfate to form the metabolite thiocyanate
Our main Thiocyanates are Sodium Thiocyanate, Potassium Thiocyanate, ammonium thiocyanate.
