不能粘结的

Adhesives can be used to bond dissimilar materials; a big advantage where dielectric corrosion may be an issue, where base materials do not lend themselves to the use of drilled holes and mechanical fasteners, or where welding may otherwise have been the joining method of choice.

In addition, there is delamination removal at weak interface due to decarburization.

普通涂层的磨损机制为微切削；纳米涂层在轻载(10 N)下，以塑性变形为主要磨损机制，随载荷增加至30 N，纳米WC粒子不能起到阻抗陶瓷球对磨副的磨削作用，而是随粘结相一起被去除，同时由于纳米涂层脱碳导致的层间结合薄弱，在滑动磨损中易发生成片剥落，耐磨性大幅下降。

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。

The layers can increase obviously the destiny of microstructure, magnetic properties Br, Hcb, m and compressive strength of the NPMC bonded by plastic. The epoxy coating can improve effectively the corrosion resistance of the NPMC and delay the rust of NdFeB particles, especially the pycno-film of the cathodal electrophoresis epoxy resin plays a dominant role in the achievements. The investigation of the temperature stability of the NPMC bonded by plastic, whose NdFeB magnetic particles are NFZ-1 and Nd〓Fe〓B/α-Fe,〓 made in China, shows that their ergo-temperatures vary with their components.

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.

得到如下结论：(1)相同的吸湿性，在30％PVF(颗粒体积分数：Particle volume fraction，PVF)前增加PVF，层间脱胶损伤值显著增加；此后损伤值的增加趋于平缓；(2)保持层间强度和PVF不变，层间脱胶损伤随吸湿率的增加而接近线性增加；(3)FCC(面心立方：Face-centred cubic，FCC)模型层间脱胶损伤的预测结果和实验数据基本吻合；同时此模型可以用于预测牙齿填充材料三点弯曲实验的临界载荷。4、建立理想牙齿修复结构，利用有限元方法研究了同时考虑聚合收缩和吸湿膨胀耦合作用下的填充修复材料和粘结界面层材料性能对牙齿修复结构的力学行为的影响，得到如下结论：(1)低弹性模量的牙齿填充修复材料能限制天然牙组织的位移，但天然牙组织的位移与粘结界面层的弹性模量无关。

The solution is to adopt a business card printing and membership card making machine instead of rubber blanket resin version, and then set the port-side seam is intended to be bonded in place rubber blanket a strip, strip of this blanket can't let paerboard, this is really looking edges, port-break light, gelatinize bond strength greatly improved after, but also to reduce the use of the cost of printing.

解决的办法是，采用一块制卡和会员卡制作机的橡皮布代替树脂版，然后将药盒边缝拟粘合的部分在橡皮布相应位置揭掉一层，使揭掉的这层橡皮布不能让纸板上光，这个办法果真见效，药盒边缝不会上光，涂胶后粘结强度大大提高，而且还降低了用树脂版制版的成本，一举两得。
