A kind of novel nano heat-insulating material
Technical field
The utility model relate to a kind of have high reflection, high adiabatic, insulation again can be anti-oxidant and corrosion-resistant also have high-temperature resistant result, economy and durability novel nano heat-insulating material.
Background technique
The descending pressure of domestic economy strengthens at present, in country " 12 " planning, energy-saving and emission-reduction are formulated to binding target: by 2015, the ten thousand yuan of GDP (gross domestic product) energy consumptions in the whole nation drop to 0.869 ton of standard coal (by calculation of price in 2005), 1.034 tons of standard coals than 2010 decline 16%, chemical oxygen demand (COD) and SO2 emissions decline respectively 8%, ammonia nitrogen and nitrogen oxide emission decline respectively 10%, during " 12 ", realize 6.7 hundred million tons of standard coals of energy saving.Visible, energy-saving and emission-reduction are shouldered heavy responsibilities, and Thermal Power Enterprises also will face larger energy-saving and emission-reduction pressure.
Current domestic thermoelectricity industry reduces discharging the requirement of index with respect to national energy-saving, generally feel difficult, arduous task.No matter, from the economic benefit of Thermal Power Enterprises self or the angle of the energy-saving and emission-reduction index indispensable and demanding task of country, the transfer efficiency that effectively improves enterprise's thermoelectricity pipe network is all very urgent.In conjunction with the actual state of enterprise, the major measure that Thermal Power Enterprises is generally taked is at present generally following several respects:
1, strengthening internal control; Be in particular in the generation of preventing to greatest extent the observable wasting phenomenas of naked eyes such as inner run, drip, leak by a series of administrative aspects.
2, drop into huge fund the capital equipments such as steam turbine are upgraded, replace the equipment of poor efficiency with efficient equipment, to reach energy-saving and cost-reducing object.
3, pipe network is carried out to energy-conservation upgrading.Be incubated the application of new technologies and materials by novel pipeline, reduce energy loss and the droop loss of steam in pipeline transmitting procedure, to reach energy-saving and cost-reducing object.
To Thermal Power Enterprises, heat supply network is exactly the lifeline of Thermal Power Enterprises, that is to say that heat supply is the central task of Thermal Power Enterprises and the foundation stone of depending on for existence and development.Therefore guaranteeing and meeting under the prerequisite of user's normal demand, how energy-saving and cost-reducing to obtain best economic benefit to greatest extent, the central task in the daily operation and management of Ye Shi enterprise.
In sum, for the present situation of current domestic Thermal Power Enterprises, be enterprise economic benefit to original pipe network insulation upgrading, most economical in energy-saving and cost-reducing, the most effectively, one of the most urgent task.
The Ministry of Construction of China clearly stipulates, requires the city heat supply engineering heat supply network transfer efficiency should be more than 90%; China is incubated and continues to use for many years traditional heat preserving method always steam line at present, and the thermal insulating material of use mainly contains: rock wool, glass wool, silicate product etc.Can not waterproof or be easy to make moist due to these materials, therefore in use, be easy to run into water or water vapor; Once and run into water, so the effect of insulation will greatly reduce until all wound lose.The thermal insulating material that particularly material such as rock wool, glass wool is made, constructs very inconvenient.Most importantly its plumage bits are easy to spread and fly upward, and human body is caused to huge injury.Its use separately energy-saving effect also not ideal native land environmental administration of man generally do not encourage enterprise to use.Therefore, we developed a kind of have high reflection, high adiabatic, insulation again can be anti-oxidant and corrosion-resistant also have high-temperature resistant result, economy and durability novel nano heat-insulating material.
