A series of polyurethane (PU), prepared by using uretonimine modified pure 4,4' diphenylmenthane diisocynate (MDI), and vinyl ester resin (VER) simultaneous interpenetrating polymer networks (SINs) with different compositions have been synthesized. Based upon the DSC, SEM and WAXD observation, the experimental results showed that the chemical bonds between the two networks had great influence on the structure, morphology and mechanical properties of these SINs. For PU/VER SIN in which there are no chemical bonds...

A series of polyurethane (PU), prepared by using uretonimine modified pure 4,4' diphenylmenthane diisocynate (MDI), and vinyl ester resin (VER) simultaneous interpenetrating polymer networks (SINs) with different compositions have been synthesized. Based upon the DSC, SEM and WAXD observation, the experimental results showed that the chemical bonds between the two networks had great influence on the structure, morphology and mechanical properties of these SINs. For PU/VER SIN in which there are no chemical bonds between the two networks, it is a thermodynamic incompatible system and exhibits phase separation morphology. This is probably related with the different formation rates of the two networks and mixing conditions for forming such SINs. For PU/VER SIN having chemical bonds between the two networks, the compatibility between the two phases and mechanical properties of SINs increased appreciably. Furthermore, the morphology and mechanical property of such SINs are also related with the mixing conditions, i.e hand mixing and reaction injection molding, for forming these SINs.

通过示差扫描量热计、扫描电镜与广角X光衍射仪研究了由碳化二亚胺改性二苯基甲烷二异氰酸酯合成的聚氨酯(PU)与丙烯酸酯类树脂(VER)形成的同步互穿网络(SIN)的结构、形态与力学性能,发现网络间的化学键对其影响极大.网络间没有化学键连接的PU/VERSINs是一个热力学不相容体系,存在显著的相分离形态,后者同时与两个网络的形成速率与工程因素有关;对于网络间有化学键连接的PU/VERSINs,两个网络间存在一定的相容性与互穿程度,故较显著地提高SIN的力学性能.

Objective:Compare of the mechanical properties of the bone cement with vacuum mixing and normal mixing.Method:Two groups of specimens of a Chinese bone cement were manufactured:in the first group the bone cement was hand-mixed as usual,in the second group the bone cement was prepared by mixing under partial vacuum.The tests of static compression strength,static bending strength,elastic modules were performed according to the standard of International Standard Organization (ISO),and fatigue strength was tested according to the criterion of German Industrial Standard(GIS).Result:When using vacuum mixing technique,fatigue strength and bending strength were significantly improved by 15% and 13% respectively.With vacuum mixing neither the static compression strength of this bone cement nor the E-modules of bending improved statistically significant.Conclusion:The values of fatigue strength and bending strength of the bone cement were improved by vacuum mixing.The method of vacuum mixing has an active significance in clinic.

目的 :比较骨水泥经过真空搅拌和普通搅拌的机械性能变化。方法 :将一种国产骨水泥分成普通搅拌和真空搅拌 2组分别制成标本 ,按照国际标准组织 (ISO)的标准测定抗静态压力强度 ,静态抗弯曲强度和弹性模量 ,按照德国工业标准 (DIN)检测抗疲劳强度。结果 :应用真空搅拌处理 ,抗弯曲强度和抗疲劳强度分别提高了 13 %和 15 % ,骨水泥的静态压力耐受强度稍降低 ,弹性模量稍提高 ,二者在统计学上无变化。结论 :采用真空搅拌骨水泥的方法 ,提高了国产骨水泥的抗疲劳强度及静态抗弯曲强度 ,在临床应用有较大的积极意义。

纯矿物试验表明,在碱性条件下DS+YD对黄铁矿有抑制作用,而对方铅矿则没有抑制作用;人工混合矿物和实际矿石试验结果证实,用石灰调浆到pH=9,组合抑制剂DS+YD能有效实现方铅矿和黄铁矿的浮选分离,精矿含Pb57.89%,铅回收率达到84.78%,并且不影响锌的浮选效果.矿物表面黄药吸附量测定结果表明,组合抑制剂对不同矿物表面竞争吸附能力的差异是低碱度矿浆条件下实现有效分选的主要原因.
