In sintering stage 2, the method that glazed tiles sinter mainly has following several:
(l) it is normal pressure-sintered:Refer to base substrate freely sintering without additional drive under atmospheric conditions, also known as pressureless sintering.
The selection of sintering temperature can cause sufficient atoms permeating with solid-phase sintering, and liquid-phase sintering can be formed liquid phase, diffusion and viscous
Flowing occurs as foundation, typically takes the 0.5 1 0.8 of key component material melting point to be advisable.Can be in sky according to pressed compact characteristic difference
Carry out, can also be carried out under a certain special gas atmospheric condition under the conditions of gas.It is significant to note that closed in sintering process
Whether the formulation of sintering curve is rationally directly connected to material and prepares success.
(2) hot pressed sintering:Higher glazed tiles are required to consistency, can use and apply a level pressure in sintering process
The method of power (inhaling OMpa 10 1), this method are referred to as hot pressed sintering.In hot pressed sintering, the diffusion of powder is compared with block under normal pressure
More, so the temperature selection of hot pressed sintering is typically lower than normal pressure-sintered temperature, sintering time is also shorter.But hot pressed sintering process
It is required that sunset, lattice are tried, there is higher requirement to mould and technological parameter, production cost is higher than normal pressure-sintered.
(3) HIP sintering:The Sintering mode unidirectionally to pressurize is typically taken during hot pressed sintering, easily causes to sinter
During pressed compact unbalance stress, grain growth shows obvious directionality, will ultimately result in glazed tiles material microstructure and
The anisotropy of mechanical property.For this problem, a powder that will can be prepared, load made of special material jacket or
Pressed compact shaping is put into the high-pressure bottle for providing counterpressure and completes sintering process, and here it is HIP sintering.High temperature insostatic pressing (HIP)
Sintering method production efficiency is high, and material wastage rate is low, and the glazed tiles material grains prepared are uniform, and consistency is high, density
Close to solid density, but hot isostatic apparatus is expensive, and operating cost is higher.At present, in the lab, some extraordinary coloured glazes
Watt, composite and hard alloy etc., prepared more using high temperature insostatic pressing (HIP) method.
(4) reaction-sintered:The characteristics of this sintering method, is course of reaction and sintering process while carries out.It is general to adopt more
Use liquid reactive sintering.Silicon carbide reaction-sintered is exactly this sintering side ' method.Reaction-sintered short preparation period, technique are simple.Lack
Point is that article construction is difficult to control, and complete reaction-sintered has certain requirement to pressed compact thickness.
(5) liquid-phase sintering:By adding low melting point sintering aid, powder is set to complete sintering process under liquid phase under high temperature,
This sintering method is referred to as liquid-phase sintering.It has to be noticed that the sintering aid of selection can not influence the performance of product, product can be improved
Performance is more preferable.Due to the difference of material transport mechanism, liquid-phase sintering densification rate is high compared with solid-phase sintering, influences liquid-phase sintering
Factor mainly has the solubility of property of liquid phase and quantity and solid phase in the liquid phase etc..
(6) microwave sintering:Microwave sintering is a kind of new material sintering process developed in recent years, and it passes through microwave
Lotus root between material internal structure, which is closed, produces energy completion sintering process.Because the energy of microwave is directly absorbed by material, institute
It is higher by much with the more other sintering methods of capacity usage ratio, meanwhile, the microwave sintering used time is short, environmentally friendly, sintering process is easier to control
System, these features also make microwave sintering turn into a focus in field of material preparation in the world, and the research to microwave sintering is held
Temperature of continuing rising.
Exhausting size for exhaust blower 7, it is necessary to see influence of the cold wind to kiln body inner chamber atmosphere into kiln body because plus
Big cold wind, zero-pressure is easily set to be moved towards sintering stage, on the contrary eutral margin can move to cooling section direction again, and these can all make atmosphere
Change.For steady pressure, it is necessary to the aperture of the first gate 5 of corresponding regulation and the second gate 6, to balance the gas of full kiln
Output, stable eutral margin.
Finally it should be noted that：Various embodiments above is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the utility model is described in detail with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, either to which part or whole
Technical characteristic carries out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
