The surface appearance and hygroscopicity of ADN after coating were analyzed by SEM and weighing method. Results show that a kind of floccule of PU is formed on the surface of ADN, which makes the hygroscopicity of ADN after coating less than that before coating evidently. When coated ADN is exposed in the atmosphere for 30 days with the RH less than 60%, the hygroscopicity of coated ADN is only 0.136% and does not increase with the increasing of exposure time.

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。

Orthogonal experiment under special condition showed that modifier M has marked effect on properties of no bake sand. Other factors such as modifier B,phosphate concentration and aluminum hydroxide have some impact on properties of binder. It can be found by experiments that strengths of no bake sand are raised notably by binder that modified by modifier B. Modifier B can reduce the strength of no bake sand at high room temperature apart from condition of low room temperature that it can accelerate the reaction and strengthen the sand. Modest content of modifier M in binder has some improvement to anti-wettability of sand. But modifier B has not such notable effect. Electronic microscope shows that near cracks in no bake product there are fibrous shape substances formed when the samples are moistured in high humidity air for sometime.
通过改性剂B对粘结剂自硬砂的性能影响试验发现,改性剂B能显著提高粘结剂自硬砂的强度,在0℃左右很低的环境温度下改性剂M有利于提高自硬砂的反应速度和砂型强度外,但在较高环境温度下,改性剂M均降低粘结剂自硬砂的强度,但是适量的改性剂M有利于改善自硬砂的抗吸湿性,而改性剂B对于改善自硬砂的抗吸湿性的作用不如改性剂M明显,电镜观察发现抗吸湿性较好的自硬砂在高湿度下存放一定时间后,在粘结膜裂纹处会形成一种绒毛状物质,该物质对裂纹具有愈合作用,这种绒毛状物质中具有改性剂M中的某种成分,且含量很高,由此说明改性剂M对提高抗吸湿性有利。

The results were found as following:(1) The damage value increases more significantly with the increase in PVF before 30% PVF, beyond which the increasing trend becomes gradually gentle.(2)Keeping the interphase strength and PVF unchanged, the damage increase with increasing moisture concentration in a nearly linear relation.(3)The results generated from the FCC model with consideration of the interphase debonding are in good agreement with the experimental data, meanwhile, the FCC model is also capable of predicting the critical load for the damaged and the undamaged dental composite subject too the 3-point flexural test.4 A 3D-fmite element analysis has been successfully exploited to examine the mechanical behavior of the restoration-tooth structure under the polymerization shrinkage and water sorption. It was found:(1) The low stiffness of the composite has the effect to limit the displacement occurring in the remaining tooth tissue. For lower interphase, the cuspal flexures are litter higher. The high interphase modulus acts as a \'shielding effect\' for stress transfer.
