The experimental results have shown good coincidence with the exponential law A new“infinite type” rotational viscometer was designed for industrial application. A correlation is suggested as follows. S_b=M/2πR_b~2L;γ_b=(S_b/k)~(1/n)=2Ω/n where K=(n/2)~nS_b/Ω~n。

用恒流出系数的毛细管粘度计测定了顺丁橡胶汽油溶液在不同剪切速率、浓度和温度下的流变特性。实验数据表明:其表观粘度符合指数定律。η_α=k~(n-1)为工业应用设计了一种新的“无穷大型”回转粘度计。计算如下式S_b=M/2πR_b~2L _b=(S_b/k)~(1/n)=2Ω/n式中x=(n/2)~n S_b/Ω~n在顺丁橡胶生产中,生胶的门尼值是最重要的质量指标之一。因此在顺丁橡胶聚合过程中,如何预测生胶的门尼值成为生产控制的关键。北京石化总厂、北京化工学院,浙江大学等提出采用胶液的粘度和折射率按式(1)进行关联:ML=0.1124η_H~(0.2941) Δ_n~(-1.470)exp(-687.0/T) (1)式中 ML 为生胶的门尼值;ηH为 Hppler 粘度计测得的胶液粘度;Δ_n 为胶液折射率和溶剂折射率之差;T 为测定温度(°K)。其中ηH 是胶液浓度 C(克/100毫升溶液)、粘均分子量 M 和测定温度 T(°K)的函数,其数学表达式是:ηH=0.0126×10~(-20)C~5·M~(3.4)exp(1410/T) (2)目前Δ_n 的测量国内有关工厂已有专门设计的连续折光仪,但ηH 的测量由于无法将 Hppler 粘度计应用于工业上的连续测量,因而必须改用其他具有一定剪切速率的粘度计(如回转粘度计),先测得胶液在一定剪切速率下的表观粘度θ_α,然后通过胶液的流变特性的研究,将测得的η_α换算成ηH。此外,在顺丁橡胶生产中,不可避免的还有一定量的胶团形成。结成大块的胶团将迅速堵塞一般粘度计的测量元件。目前北京石化总厂应用的进口双圆筒连续回转粘度计就碰到这种困难。所以设计一种独特的连续工业用粘度计,使能在含有大块胶团的粘性溶液中进行表观粘度测定,也是迫切需要解决的。

The Corrosion behaviour of four common organophospho-pesticides(para thion, Dimethoale, Dichlorus and Kitazin) to four organic coatings(PVF, T09-17, G04-6 and C04-2), the influence of these pesticides on corrosion state and degree of these coatings under different concentrations and temperatures have been studied. In order to evaluate corrosion state objectively, a quantitative counting method for grading corrosion resistance of coatings to pesticides is proposed. With this method, test results are treated, and corrosion data curves of coatings under different conditions are also drawn. By comparing and analysing these curves, some useful conclusions are obtained.

The inhibiting effect of benzothiazole(BT)and 2-mereaptobenzothiazole (MBT)and the effect of -SH group in this respect on the corrosion of a car- bon steel in HCl solutions at various concentrations and temperatures were investigated.It is shown that the inhibiting effect of MBT is much more pro- nounced than that of BT due to increased surface activity of BT raised by -SH group.Langmiur isotherm equation is observed by both compounds ad- sorbed on steel surface when their concentrations in HCl solutions are not very high.The values of the equilibrium constant B of the adsorption process were determined at θ=0.5.It was found the value of B for MBT (10~5 is of one order of magnitude higher than that for BT(10~4).Impedance measure- ments showed that for both compounds the data of electrode boundary capa- citance which vary with the value of θ fall on the same straight line,and the same value of boundary capacitance (14μF/cm~2)was obtained by extra- polating the experimental data to θ=1.These facts imply that there are no changes in the characteristics of adsorption and the mode of arrangements of the molecules adsorbed on the electrode surface when the -SH group is intro- duced onto the BT.Polarization measurements indicated that both inhibitors belong to the mixed type with predominant anodic control.However,the inhibitive action to the cathodic reaction of the corrosion process is some- what strengthened by introducing the -SH group onto BT molecules.

本工作研究和比较了苯并噻唑与2-巯基苯并噻唑在 HCl 溶液中对碳钢腐蚀的缓蚀行为。以探讨巯基(-SH)的作用。结果表明,巯基的引入明显地改善了苯并噻唑的缓蚀性能。这种作用主要是通过提高苯并噻唑的表面活性而达到的。琉基的引入并没有改变苯并噻唑的吸附规律和在碳钢电极上的排列方式。极化曲线的结果表明,二者都是以抑制阳极过程为主的混合型缓蚀剂。但是,巯基的引入明显地增加了苯并噻唑对碳钢腐蚀的阴极过程的抑制能力。
