铬鞣的

The results have indicated that acid bating fits to bating of sheepskins especially for sheepskin's loose structure because of more alleviate action of acid enzymes, and acid bating has little loss of hide substance.

结果表明，酸性酶软化作用温和、深透，对胶原损害小，特别适合于组织结构疏松的绵羊皮生产。酶制剂用于绵羊服装革鞣前准备其它关键工序，可减少硫化物、表面活性剂等有害物质的用量，提高铬结合，减少作用时间，提高面积得率和成革质量。

We find good ways to hydrolyze and modify by experiments. Through the experiment, good tanning, retanning and filling properties, as well as, better chrome exhaustion are found in the modified products, with the help of selecting suitable ways to hydrolyze and modify the chrome shavings. The crust leather is possessed of fullness, softness, good dyestuff...

通过实验研究，选择适宜的水解铬革屑的方法和改性条件，发现改性产品在应用中具有较好的鞣制复鞣填充作用，可促进对铬的吸收，坯革丰满、柔软、有弹性，粒纹清晰细致；对染料吸收性好、着色均匀；并可提高成革的收缩温度，降低废液中的含铬量

The chrome reduced tannage with resin tanning agent and modified glutaraldehyde pretanning, and combination Al-Cr tanning were investigated.

研究了树脂鞣剂、改性戊二醛鞣剂预鞣，铝－铬结合少铬鞣制轻革的工艺及方法。

The subject of this seminar was divided into six sessions which were(1)clean technology and legislation update;(2) cleaner production through advanced process control;(3)beamhouse pollution control:practical views;(4)practical experiences in environmental management;(5)effective chrome tanning and (6) pollutioncontrol in leather finishing.

会议收集了22篇来自制革者和可能对制革清洁技术提出建设性意见的优秀论文。会议所分六个专题报告都取得圆满结果，这六个专题是：1。清洁技术和最新立法；2。通过先进的工艺控制进行清洁生产；3。准备工段污染控制：实际展望；4。环境管理中的实践经验；5。有效的铬鞣；6。皮革涂饰中的污染控制。

A series of novel chrome-free tanning agent s were synthesized with erea,glyoxal,glycine and melamine.

合成了6种新型的同系列的无铬鞣剂。

The experiments are as follows: Many times degreasing,short ratio of liquor,unhairing and liming with so- dium sulfide,reliming,bating with mixture enzymes in low temperature,retan- ning with modified glutaraldehyde—chrome,many times fatliquoring partly,and so on.

陕西猪皮质量常比我国南方猪皮质量差，为了提高它的使用价值，我们做了大量的试验与观察，找出了合理地制造服装革的方法，如多工序分次脱脂，少浴硫化钠脱毛浸灰，复灰，混合酶低温软化，改性戊二醛-铬结合复鞣，多工序分次加油等，生产出&薄、轻、软&的服装革。

Comparing 10 kinds of fat liquors, the penetrability of fat liquoring agents in the chrome-free pigskin garment leather, and the physical-mechanical properties of fatliguored chrome-free leather were studied.

对比研究了磺化油加脂剂STO、SEO、SHO、KS-1和6种常用加脂剂在无铬鞣猪皮服装革中的渗透情况及其加脂后坯革的物理-机械性能。

Compared with 6kinds of single component in fat liquors,the penetribility of 4 kinds of sulfonated fat liquoring agents STO,SEO,SHO,SS-1 in the chrome-tanned leather,and the physical-mechanical properties of chrome-tanned leather after fat liquoringwere studied.

以6种常用加脂剂单一组分为参比，研究了四种磺化油加脂剂STO、SEO、SHO、SS-1在铬鞣革中的渗透情况及其加脂后坯革的物理-机械性能。

The hydrolysis of chrome-tanned shavings modified by Cr-Al complex and the application of its product in tanning and retanning are discussed in this paper.

探讨了用铬—铝络合物改性铬革屑水解液及其产品在鞣制或复鞣中的应用。
