Description
Technical field
The present invention relates to the preparation method of double-faced flexible aluminium foil, particularly relate to a kind of dusting device spraying macromolecule and be combined
PTC powder body prepares the method for double-faced flexible aluminium foil.
Background technology
Along with developing rapidly of science and technology, society every profession and trade particularly composite, electronic material, decorative material etc.
The demand of functional aluminium foil is increased day by day.Functional aluminium foil has become as at present at the functional energy and electronic system product
In play support, the critical material of PCB of interconnection components and parts effect, it is called electronic product signal and electric power transmission, links up
" neutral net ".Aluminium foil is as the basic material of electronics industry, and its development follows the development of PCB technology always, and PCB skill
Art then improves constantly along with the with rapid changepl. never-ending changes and improvements of electronic product.The development of IT product technology promotes PCB towards multiple stratification, slim
Change, densification, high speed, highly reliableization, functionalization direction are developed, and therefore develop and more have high-performance, high-quality, Gao Ke
Aluminium foil market prospect by property, functionalization is boundless.
Heyman from nineteen fifty Philips company of Holland et al. can obtain positive temperature after finding the pottery semiconducting of BaTiO3 system
Since coefficient (PTC) characteristic, people are more and more deep to its understanding.It is meanwhile, the most increasingly extensive in its application aspect,
Penetrate into the every field such as daily life, industrial or agricultural technology, military science, communication, aerospace.PTC thermistor heater element is
The modern product down to high-tech tip in the future.It is widely used in light industry, house, traffic, space flight, agricultural, medical treatment, ring
Guarantor, mining, civilian apparatus etc., it is with nickel, chromium silk or far infrared etc. compared with heater element, the advantage with brilliance.When in PTC unit
When part applies the intensification of AC or DC voltage, below Curie-point temperature, resistivity is the lowest；When once surmounting Curie-point temperature,
Resistivity increases suddenly so that it is electric current drops to stationary value, reaches A.T.C, constant temperature purpose.PTC-element adstante febre is not
Rubescent, the flames of anger (resistance wire is rubescent and has naked light), nonflammable.When PTC-element environment temperature surmounts limit value, its power is automatic
Drop to equilibrium valve, danger of combustion will not be produced.The energy input adoption rate formula of PTC-element, current limiting effect, compare nickel filament
Electric power is also saved Deng the switching regulator energy input of heater element.Ptc material has macromolecular material class and ceramic-like two kinds, ceramic-like
PTC-element, originally as oxide, the high-temperature oxydation drawback of Ni-Cr free silk, does not has the frangible phenomenon of infrared tube yet, and the life-span is long.And
Porous type is more longer than the anapsid life-span.PTC-element itself is temperature automatically controlled, is not required to separately add A.T.C line unit.Porous
Type PTC more need not other heat abstractors, is also not required to use conducting resinl.PTC-element is at low pressure (6-36 volt) and high pressure (110-240
Volt) under can normally use.Low pressure PTC-element is applicable to all kinds of low voltage heater, instrument low temp compensating, on automobile and computer
Heater on peripheral equipment.High pressure PTC-element is applicable to the heating of following electrical equipment: electric thermal-insulation plate, shoe baking device, heat
Melting glue gun, electric cooker, electric shoes, electric mosquito heater, intravenous injection heating, light-weight plastic closing machine, steam Comb, steam occur
Device, humidifier, curler, video tape recorder, photocopier, automatic vending machine, hot-air screen, hand warmer, tea drier, Water pipe heating
Device, travelling dryer, finish-baking room for automobile, liquefied gas bottle heater, shower, cosmetology device, Electric heating table, baby bottle thermostat, electricity
Hot moxibustion apparatus, electric hot water bottle, electric blanket etc..
The appearance of ptc material, can solve that the speed of traditional switch is fast not and the problem of the biggest these two aspects of capacity.
Along with the development of science and technology and updating of technique, the characteristic of PTC-element will be more and more perfect, and its normality can be incited somebody to action by galvanization
It is further improved, a field technology revolution of traditional switch may be caused in AC and DC field, for linear quadratic control equipment
Also having a wide range of applications, it will be substantially reduced the manufacturing cost of electronic equipment, improve economy that electronic system runs,
Reliability.
Ptc material processing is due to barium titanate ceramics material, and it is more difficult that tradition processing homogeneity controls, and limits PTC
The application of material.
Tradition prepare PTC components and parts and is processed respectively with electrode due to the restriction of technique, PTC components and parts, then with pole plate weldering
Connect or be cemented to device, based on Miniature component, there are no the report of jumbo ultra-thin function aluminium foil processing.
