Concrete method of recovery of energy from renewable metal clothes
。 The reason for this is that (1) of toxic gases. Polyvinyl chloride (PVC) combustion generated when oxygen chloride gas; Polyurethane (pu) is burned to produce hydrogen cyanide gas. (2) smoke. Pure metal coat hooks need plenty of air when waste burning, for the urban garbage burning air demand ~ times, to achieve complete combustion, ordinary incinerator can't satisfy this requirement, therefore, waste metal clothes hook will burn and produce smoke from lack of oxygen. (3) ash. Polyvinyl chloride (PVC) metal clothes generally contain lead salt and other heavy metal salt stabilizers, heavy metals such as lead in ash after combustion is difficult to deal with. (4) water acidification. Polyvinyl chloride (PVC) combustion to produce hydrogen chloride gas is absorbed by water or chemicals, formation of acidic water is difficult to remove. (5) high combustion temperature. Scrap metal coat hooks than those produced by the burning of municipal waste combustion temperature is much higher, normal incinerator unbearable, furnace high temperature caused damage. 6. Corrosive materials. Scrap metal clothes combustion can be induced in hydrochloric acid, ammonia, sulfur dioxide, sulfur trioxide, NOX and RCOOH corrosive substance, such as corrosion damage in furnace, more will accelerate the corrosion of the gas in the waste water. In a word, for the pure metal coat hooks of waste incineration needs specially designed incinerator.
Waterloo and Cambridge
These new hinges are the most effective way to create a safe weather seal around the garage door, while saving money on wasted energy.
Load it with a card, turn it off for travel and open it to show your card in both sections
Put the same card in two parts or show two different cards!
My challenge for myself is to create a container that shows both business cards and ships them.
