Effects of dry temperature and dry time on properties of heat cured sand and the relationship with binder composition are as follows:sands bonded by binders that are not modified have high strength when dry temperature is high and dry time is long,but their anti-wettability power is poor . Sands bonded by binders that are modified by B but not modified by M can be dried quickly and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M but not modified by B can also be dried quickly to obtain maximum strength,then the strength becomes lower when they are dried continually for more time. and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M as well as by B at the same time can be dried quickly to obtain maximum strength at low temperature and short time. But the anti-wettability of sand mold is best when they are dried at high temperature and long time.

烘干温度和烘干时间对热硬砂性能的影响及其与粘结剂改性的关系是:未经改性剂B和改性剂M改性的粘结剂砂,脱水速度较慢,烘干温度越高,时间越长,则硬化强度也越高,但未经改性的粘结剂热硬砂的抗吸湿性较差;经改性剂B而不经改性剂M改性的粘结剂热硬砂,烘干硬化速度较快,强度也高,但在高湿度下的抗吸湿性不好;经改性剂M改性而不经改性剂B改性的粘结剂热硬砂,烘干时强度先随烘干时间升高至最大值后,继续烘干时强度又出现下降;经改性剂B和经改性剂M共同改性的粘结剂热硬砂能在短时间和较低的烘干温度下就可烘干到最高强度,即烘干脱水的速度较快,但试样的抗吸湿性差,若在更高温度和更长时间下烘干,试样的抗吸湿性得到改善,综合考虑烘干强度和抗吸湿性要求,对于φ30×30mm试样,理想的烘干温度是200℃,烘干时间20分钟。

Calcium montmorillonite was prepared by purifying LeXi bentonite with wet method two times. After purification, sodium modification of Ca-M was studied. A series of Fe/Cr-pillared montmorillonites were prepared with conventional method using sodium montmorillonite as experimental materials, and synthesis condition of Fe/Cr-PILM was studied and optimized. In order to shorten the preparation cycle of PILM by overleaping the step of sodium modification of Ca-M, the pretreatment technique for Ca-M has been pointed out for the first time. A series of PILMs were prepared with hydrothermal method using pretreated Ca-M as starting materials, which show that pretreatment of Ca-M is feasible.

This paper studied the relationship between impulsive moment of radial tidal current and Alai phenomena, and concluded that: M acting on the earth's axis inspires Chandler wobble; the change of M depends on the interaction of the water, tidal force and the effects of the earth's rotation; under certain conditions, M changes dramatically during eclipse, which makes the amplitude of Chandler wobble change in the form of pulse.
