Preparation method of low-temperature sintered shrinkage-deformation-free microporous ceramic irrigation emitter
The invention belongs to the technical field of agricultural water-saving irrigation in arid regions, and particularly relates to a preparation method of a low-temperature sintered shrinkage-deformation-free microporous ceramic irrigation emitter. Prepared ceramic powder has the characteristic of softening and melting at the temperature of 600-650 DEG C, so that a blank prepared from quartz powderand the ceramic powder through mixing and mould pressing can be used for firing the microporous ceramic irrigation emitter meeting the requirements of mechanical properties, open porosity and pore diameter only at the temperature slightly higher than the temperature of 600-650 DEG C. In the sintering process of the ceramic product, the higher the sintering temperature is, the higher the shrinkagerate of the ceramic product is. The sintering temperature of the microporous ceramic emitter disclosed by the invention is only 680-720 DEG C, and the sintering temperature is far lower than the sintering temperature reported in comparative literatures in the background art, so that the microporous ceramic irrigation emitter prepared by the invention certainly has extremely low shrinkage rate, the manufacturing and using cost of the microporous ceramic irrigation emitter can be greatly reduced, and the microporous ceramic irrigation emitter has great agricultural popularization potential andmarket prospect.
本发明属于旱区农业节水灌溉技术领域，尤其涉及一种低温烧结无收缩变形的微孔陶瓷灌水器的制备方法。本发明制备的陶瓷粉具有在600‑650℃即可软化熔融的特点，因此由石英粉和陶瓷粉混合模压制成的坯体，只需在比600‑650℃略高的温度下即可烧制出满足力学性能、开口孔隙率和孔径要求的微孔陶瓷灌水器。在陶瓷制品的烧制过程中，烧结温度越高，陶瓷制品的收缩率越大。由于本发明微孔陶瓷灌水器的烧结温度仅为680‑720℃，远低于背景技术中对比文献报道的烧结温度，因此本发明制备的微孔陶瓷灌水器势必具有极低的收缩率，可大幅降低微孔陶瓷灌水器的制造和使用成本，极具农业推广潜力和市场前景。
