Description
Technical field
The present invention relates to resin solidification technical field more particularly to a kind of microwave-ultraviolet combination solidification diamond resins
The method of line.
Background technique
Currently, Chinese photovoltaic enterprise has located in terms of silicon wafer, sapphire cutting technique, cell piece and component production technology
In global advanced level.With the rapid emergence of the emerging markets such as China photovoltaic market, overseas market, photovoltaic enterprise is to base
The requirement of plinth Technology Progress is increasingly urgent to, and being constantly progressive of crystal silicon chip cutting technique has become domestic slice enterprise and seize not
Carry out the innate need of the economy of market competition commanding elevation.
It is realized to reduce cost manufacturer by the following means:
1, kerf loss is reduced, it is that cutting process itself directly contributes that kerf loss is main related with cutting linear diameter
Significant loss；
2, crystal silicon chip is allowed to become thinner, overall silicon consumption of raw materials amount 60% can be reduced by reducing crystal silicon chip thickness；
3, Buddha's warrior attendant saw blade cutting speed of new generation is required to be promoted again, so that cutting load is improved, the gold of more high productivity
Rigid scroll saw system can reduce board quantity under same silicon wafer yield.
It can be seen that the research and development of Buddha's warrior attendant line cutting technology has become a kind of promotion photovoltaic enterprise raising core competitive power energy
The development of the essential condition of power, new process resin diamond wire is more necessary, is very beneficial for the reduction of manufacturer by a relatively large margin and sets
The cost of standby, operator and maintenance.
Microwave is a kind of frequency electromagnetic waves, and frequency is 300 megahertzs~300,000 megahertzs, and wavelength is 1 millimeter~1 meter.Microwave
Has specific to electric field the features such as cycle of oscillation is short, penetration capacity is strong, can produce specific effect with matter interaction.Tradition
Drying means, such as flame, hot wind, steam, electric heating are external heat drying, after surface of material absorbs heat, are passed through heat
It leads, inside heat leak to material, heat up drying immediately.And microwave drying is then entirely different, it is a kind of internal side heated
Method.Material is in cycle of oscillation extremely short microwave high-frequency electric field, and internal molecule can occur polarization and along microwave electric field
Direction proper alignment, then change with the interaction in high-frequency alternating field direction rapidly and rotate, and generate violent collision and
Friction (each second is up to more than one hundred million times), as a result a part of microwave energy is molecular motion energy, and is shown in the form of heat
Come, so that the temperature of water is increased and is left material, to make dry materials.That is, after microwave enters material and is absorbed,
Energy is in material dielectric internal conversion at thermal energy.Therefore, microwave drying is using electromagnetic wave as heating source, dried material
Originally as a kind of drying mode of heater.In traditional drying process, to improve rate of drying, elevated external temperatures are needed,
Temperature gradient is increased, however is easy to produce the scorched outside and underdone inside phenomenon of material therewith.But when using microwave heating, no matter material shapes
How, heat can uniformly penetrating.Material of different nature is different to the absorption of microwave, under microwave action, the drying of material
Rate reaches unanimity, homogeneous heating.Microwave is that electric energy converts, and opens power supply and starts to work, does not need to preheat, no waste heat
Generate, and microwave equipment is compact-sized, auxiliary facility is few, land occupation it is few (only the 20% of traditional drying occupation area of equipment~
30%), easy to operate, it can work continuously, (by PLC programming Control and prison can be passed through convenient for automated production and business administration
The overall process that visual organ sees drying, arbitrarily adjusts temperature between room temperature~1000 DEG C).Microwave drying is faster than oven drying speed
10~20 times.The energy utilization rate of microwave drying process is higher, this is because the heat of microwave directly results from inside material, heat
Loss is few, and the thermal efficiency is high (up to 80% or so).Studies have shown that electrothermal drying something material power consumption is 100 kilowatts, and uses microwave
The material power consumption of dry equivalent of the same race is only 20 kilowatts.Moreover, microwave equipment, almost without environment and noise pollution, processing workshop can
Substantially improve working environment.
The electric heating of thermosetting resin of the fixed grain scroll saw of resin bonding agent diamond scroll saw due to being used as bonding agent is solid
It is too long to change the time, material internal inevitably there is temperature gradient, the result is that the solidification of resin be difficult it is uniform completely, from
And it is easy to generate biggish internal stress and production cost is excessively high.Using solidified resin material can be evenly heated the characteristics of microwave heating
Material, rapidly and uniformly solidifies to be very beneficial for thermosetting resin, and under the effect of microwave non-thermal effect, microwave curing
Effect is more preferable.
In addition to this, it is acted synergistically using microwave and ultraviolet light wave, while carrying out heat cure and light-cured composite
Solidification, had both been utilized the heating effect and non-thermal effect of microwave, and had promoted the curing reaction process of heat reactive resin, and be utilized micro-
The ultraviolet light wave that wave can excite electrodeless ultraviolet lamp to generate solidifies light-cured resin, to simply, easily and fast realize
Resin solidify use of the invention can microwave curing heat reactive resin and light-cured resin in a short time, it is faster than normal temperature cure
60 times, scroll saw low manufacture cost newly developed, mechanical performance and processing performance should all be good.Wave solidifies to the heat-resisting of raising product
Property there is positive effect, microwave curing to resin thread tensile strength without change, after adding reinforcing material, microwave non-thermal effect and purple
Outer cured synergistic effect can also reinforced resin line tensile strength.
