There exist some unassailable problems in traditional chrome tanning, such as low exhaustion of chrome, salt pollution from pickling, and time-consuming process, etc.

传统浸酸铬鞣存在着一些不容忽视的问题,如:铬的吸收率低,浸酸时带来的盐污染,鞣制周期长等。

To obtain salinity reduction in conventional pickling process, application of Cr-Al combination tanning to goat bated hides pretreated by Potash alum was investigated to substitute for salt pickling in single-factor test method.

为减少制革常规浸酸工序的盐污染,采用单因素试验方法进行了用明矾预处理山羊软化裸皮以代替食盐浸酸及铝铬结合鞣制的工艺实验。

The results of research on the factors affecting titanium tannage show that high concentration NaCl medium has larger negative effect on titanium tannage. When the NaCl concentration exceeds 5%, the titanium tanning action is reduced rapiddly. Traditional NaCl pickling is unsuitable for titanium tannage, tanning in water medium directly, the best tanning effect can be obtained, so titanium tanning can not only eliminate chrome pollution, but also diminish salt pollution. The optimum tanning conditions for HPZ-Ti tan liquor are pH3. 5, TiO〓 offer of 7. 5%(based on the weight of 65% moisture pelt), the best Bascity of tan liquor is between 30% and 50%.

以HPZ—Ti鞣液为基础,研究了不同鞣制介质,鞣制pH值,鞣剂用量和浓度,鞣液的碱度,不同提碱剂,不同的预处理和后处理等因素对钛鞣的影响,结果表明:高浓度的NaCl溶液介质对钛鞣有很大的负面作用,当介质NaCl浓度超过5%,革内钛的结合量和革的Ts明显降低,传统的高浓度NaCl浸酸工艺不适合于钛鞣,在水介质中直接鞣制效果最好,所以钛鞣不仅消除了铬污染而且大大降低了盐的污染。

With chromium phosphomolybdate as catalyst and H2O2 as oxidant,catalytic oxidative removing of dibenzothiophene in n-octane under microwave irradiation was studied.

以磷钼酸铬盐为催化剂、过氧化氢为氧化剂,研究了微波辐射加热下模拟汽油中二苯并噻吩的氧化脱除。

The result showed that some of properties of the leather made by this new technique are better than the ones made by normal process. The new technique without pickling not only leave pickling and basifying out of consideration, but also reduce chrome and clears up the pollution of salt brought from pickling to the environment.

结果表明,与常规浸酸铬鞣法相比,采用C-2000铬鞣剂及相应工艺鞣制的蓝湿革与成革的某些性能得到了提高,可以省去浸酸工序,简化工艺操作,减少酸和盐的污染,降低生产成本。

An extremely brittle Fe-Cr phase that can form at elevated temperatures in austenitic and ferritic stainless steels.

奥氏体和铁酸盐不锈钢在高温下形成的非常易碎的铁-铬相位。

The workpiece with a chrome, zinc, cadmium plating, copper, tin, lead, gold plating imitation oxide, zinc phosphate salt processing, pickling treatment, electrolytic processing capacity.

具有对工件进行镀铬、镀锌、镀镉、镀铜、镀锡、铅、仿金电镀、氧化、锌磷盐处理、酸洗处理、电解加工等能力。
