Our factory possesses advanced production equipment, rich production experience, strong technical force, products are mainly for the ss-218 methyl tin mercaptide heat stabilizer, MBS-enhancer, ACR processing aid, such as plastic.

我厂拥有先进的生产设备，丰富的生产经验，雄厚的技术力量，产品主要为 ss-218甲基硫醇锡热稳定剂、MBS-增强剂、ACR塑料加工助剂等。

By the method of decreasing the concentration of the sample solution and adding NaOH , both matation of pH of sodium methyl mercaptide and NaOH may be differentiated.

采用降低样品溶液浓度和添加NaOH的方法，区分了甲硫醇钠和NaOH的两个滴定突跃，分析结果令人满意。

It has been discovered that the carboxylic ester rare earth salt is equivalent to the organotin mercaptide stabilizer in thermal Processing stabilisation of PVC by the statically and dynamically thermal methods.

用静态热稳定和动态热稳定方法比较了羧酸酯稀土与有机硫醇锡对PVC加工热稳定作用，发现它们的稳定效果相当。

All results show it is compeletely possible to replace the organotin mercaptide by the carboxylic ester rare earth salt as a stabilizer for rigit transparent products.

所有研究结果表明，羧酸酯稀土完全有可能替代有机硫醇锡作为PVC的稳定剂用于硬质透明PVC制品。

Rheological behaviours have been investigated by means of Haake torque rheometer and AG-10TA universal testing machine. It has been showed that the melt viscosity of PVC/carboxylic ester rare earth salt compound is some greater than that of PVC/organotin mercaptide compound, which can not bring unfavourable consequences at the processing level.

用HAAKE转矩流变仪，AG-10TA万能材料试验机的流变装置对两种稳定剂与PVC的复合物的流变性能进行比较，发现羧酸酯稀土与PVC复合物的熔体粘度在相同实验条件下比有机硫醇锡与PVC复合物的熔体粘度略大，但不会带来加工上的困难。

When the antimony tri amount reaches 1.5 shares, it will show the optimal stabilizing effect. It also has synergistic effect with calcium stearate and barium mercaptide, when it was mixed with barium mecaptide with 3:1 ratio, the long-term stability of PVC could be raised remarkably.

热老化研究表明，当合成产物添加量达1.5份（PVC质量为100份）时，PVC树脂的热稳定时间为18 min（200℃），当其与硫醇钡以质量比3：1复配时，可显著提高PVC制品的长期热稳定性。

Taking into account the fact that there is synergistic combination of the mixture stabilizer of the carboxylic ester rare earth salt and organotin mercaptide in thermal stabilization of PVC, we consider it more practial to replace partically the organotin mercaptide by the carboxylic ester rare earth salt.

特别是部分替代有机硫醇锡可发挥它们之间的协同效应，更具有实用性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
