Description
Technical field
The invention belongs to heat-barrier material manufacture field, more particularly to a kind of environment-friendly light heat-barrier material processing unit (plant) and adds
Work method.
Background technology
Heat preserving and insulating material has the spies such as insulation, protection against the tide, tensile strength height, is widely used in building, industry, traffic fortune
The various fields such as defeated.Benefit from energetically support and the continuous intensification of urbanization degree of the country to energy-conserving and environment-protective, insulation
Material will face the huge market demand;Simultaneously as the breakthrough of technology and the integration of industry, following insulation industry are concentrated
Degree will be improved, and competition situation is constantly broken up.
Now, global heat preserving and insulating material just protects integrated direction hair outside towards efficient, energy-conservation, thin layer, heat-insulated, waterproof
Exhibition, in Development of Novel heat preserving and insulating material and meets structural thermal insulation power-saving technology simultaneously, more emphasizes targetedly exhausted using insulation
Hot material, by standard criterion design and construction, make great efforts to improve insulating efficiency and reduce cost.Numerous and confused expansion thin layer is heat-insulated both at home and abroad
The research of thermal insulation coatings.
China's economic development is rapid, and the development of production of energy relatively lags behind much, and solve energy shortage one is best
Method is exactly to save, that is, reduces heat loss, improve the utilization ratio of heat energy, reduce energy waste.Energy conservation project is regarded in the world
For " the 5th energy ", same to oil, arranged side by side five big conventional energy resource of coal, natural gas and electric power, and one of main measure saved is just
It is development and using heat preserving and insulating material.Heat loss can be effectively reduced using heat-barrier material, saves fuel, while can improve
Work situation, ensure safety in production, improve work efficiency.
Hydrophobicity is heat-insulating material important development direction.The water absorption rate of material should be examined when from heat-insulating material
The key factor considered, the thermal conductivity factor of water at normal temperature is 23.1 times of air.It can not only be dropped significantly after heat-insulating material water suction
Its low heat-insulating property, and can accelerate to corrosion of metal, it is extremely harmful.The gap structure of insulation material is divided into connection
It is type, enclosed type, type semienclosed several, except the space of a small number of organic foam plastics is most be enclosed type in addition to, other insulation materials are not
How is pipe gap structure, and its material all absorbs water in itself, is absorbed water plus the capillary percolation of connectivity gap, therefore overall water absorption rate is very
It is high.Hydrophobic, water absorption rate are high for most of heat-insulation materials at present in China, so to the waterproof requirement of outer jacket with regard to ten
Divide the expense for strictly, adding outer jacket.Organic silicon hydrophober in modifying agent at present, it is that the more general one kind of insulation material is high
Hydrophober is imitated, its hydrophobic mechanism is to utilize chemical affinity stronger between organo-silicon compound, with inorganic silicate material,
Effectively to change the surface characteristic of silicate material, hydrophobic effect is made up to.It has stability is good, cost is low, construction
The features such as technique is simple.
The insulation material of Development of Novel is also the Main way of a research.At present, there are several novel heat insulation materials
Material(Such as nano-pore heat insulating materials, composite insulation material asbestos alternative etc.).Nano-pore heat insulating materials:With nanometer technology
Continue to develop, nano material is increasingly favored by people.Nano-hole silica insulation material is exactly nanometer technology in thermal insulating material
The new application in material field, most pore sizes in composition material are preferably in nanoscale.According to molecular motion and collision
Theory, the heat transfer of gas is mainly the molecule with the relatively low velocity of low temperature side by the molecule of the fair speed of high temperature side
Mutually energy is transmitted in collision.Because the main component nitrogen in air and the degrees of freedom of oxygen are in 70nm or so, nano-pore
When the pore size that silicon dioxide microparticle in siliceous heat-insulating material is formed is less than this critical dimension, material internal eliminates the need for
Convection current, the heat transfer of gas molecule is inherently cut off, so as to obtain than without the lower thermal conductivity factor of convected air.Asbestos
The development and application of substitute:Mineral wool is one kind of man-made mineral fiber, and its product unit weight is small, and thermal conductivity factor is low, heat insulation
It is good with sound absorbing capabilities, and with it is corrosion-resistant, will not go rotten, be not afraid of damage by worms, be heat-resisting, be freeze proof, antidetonation and good chemical stability
Deng excellent properties.Using when, it is easy for construction, cheap, be a kind of infant industry insulation material.In recent years, mineral wool and its
The production of product is developed by leaps and bounds with Chinese society doctrine building cause, and product quality improves constantly, and kind is on the increase(Have
Blanket of glass wool, seam felt, overlay coating seam felt, shell and cotton plate etc.), be widely applied to oil, chemical industry, communications and transportation,
Car and boat manufacture, machine-building, industrial construction etc..
Multi-functional compound insulating material is developed, the insulating efficiency of product is improved and expands the application surface of product.Use at present
Insulation material application upper all various degrees the defects of:Under the state containing moisture of calcium silicates, easily exist corrosive
Calcium oxide, and due to possessing moisture in long-time, be not easy to use at low ambient temperatures;Glass fibre easily absorbs moisture, is unsuitable for
Low temperature environment, it is also unsuitable for more than 540 DEG C of temperature environment;Mineral wool equally exists water imbibition, should not be used in low temperature environment, only
It can be used under the hot environment in the absence of moisture;Polyurethane foam should not be used under high temperature with polystyrene foam, and inflammable,
Shrink, produce poison gas;Foam glass should not be used under temperature state jumpy due to sensitive to thermal shock, so in order to
Overcome the shortcomings of heat preserving and insulating material, various countries develop light multifunction compound insulating material one after another.
High temperature insulating material came out in 1928 in the U.S. and West Europe, is rapidly promoted and used, such a lightweight
Material is energy-saving and environment-friendly to possess good development prospect, so there is numerous scientific workers to be engaged in this respect work at present
Make.Organic chemical synthesis class material includes polystyrene foam, rubber-plastic sponge, PVC foamed plastics, calcium-plastic board, polyurethane foam
And the material such as phenol formaldehyde foam.These materials have the characteristics that light, high insulating effect, are widely used in freezer, refrigerator, compound
Colored steel, oil product storage tank, oil pipeline and light-duty inner wall sandwich, ceiling board, abatvoix etc..Foamed and manufactured fire-retardant fireproof
Sheet material, its heat insulation performance is suitable with polyurethane foam, and thermal conductivity factor is 0.043W (m2 K), phenolic foam material anti-flammability
Its oxygen index (OI) of fire retardant can not be preferably added up to more than 35%.Do not burn in atmosphere, do not melt, do not drip in flame, a charcoal
Change, do not shrink, low cigarette, low toxicity, being 5.7% through examining maximum smoke density, this is that polystyrene foam and polyurethane foam can not compare
Intend.Through examining, thick 40mm phenolic foam boards make wall core its fire endurance and are more than 2h, and it is 78 DEG C to carry on the back fiery face maximum temperature
(standard regulation fire endurance back of the body temperature is no more than 180 DEG C).Because phenol formaldehyde foam density is big, water absorbing properties are good, occupies very in flower arrangement industry
Consequence.But phenol formaldehyde foam bulk strength is poor, and condition of molding requires higher, foam-in-place difficulty etc..A small amount of processing
Former is external high price import, therefore can't be formed commercially produce at present.
