氯丁胶粘剂冷粘运输带 总被引:1,自引:0,他引:1
一、氯丁胶粘剂的特性简介: 氯丁胶粘剂是以聚氯丁二烯类橡胶为骨架主料的橡胶类胶粘剂。由于氯丁橡胶分子结构规整、晶化程度高,结晶速度快,又有极性较大的氯原子存在,因而即使在室温下不硫化也具有较高的内聚强度和较好的粘附性能。氯丁胶粘剂初粘力较强,适用范围广,对不同的材质或具有不同膨胀系数的材料均具有良好的粘合力。特别是它能在室温下固化,不需要像其它胶粘剂那样进行加热硫化。因此这种胶粘剂节约能源,操作简 相似文献

A semi-empirical equation of state for metals is described. Its capabilities are demonstrated by the example of the equation
of state for aluminum. New experimental data are presented on the location of the isentrope of aluminum for unloading from
the state at p = 229.71 GPa on the shock adiabat to an aerogel (SiO2) of density 0.08 g/cm3.

In the present article, chitin from crab shell was systematically deacetylated using a NaOH treatment with control of the reaction time. The degree of deacetylation, monitored using solid-state NMR, revealed that the reaction was pseudo-first order. Based on this, swollen and NaOH-saturated particles are proposed as the reaction system. The weight loss of the partially saponified and neutralized samples after HCl hydrolysis increased linearly with the degree of deacetylation. The crystallinity of the samples was found to increase after acid hydrolysis. According to conductimetric titration, the surface charge density of the crystallites, after acid hydrolysis, was found to increase with base treatment time. The effect of surface charge on the formation of a chiral nematic phase, due to the rodlike nature of the crystallites, was explored. These results show that because the contribution of charged particles to the ionic strength was significant the double layer compression was affected, especially since the surface charge density was close to the Manning limit. © 1997 John Wiley & Sons, Inc.
