端羧基树枝状聚合物铝无铬鞣剂的广泛应用
随着人们环保意识的增强，铬鞣所带来的负面影响已经不容忽视，因此，生产无铬、少铬鞣剂是皮革工业最主要的发展方向之一。端羧基树枝状聚合物鞣剂克服了铝鞣剂不耐水洗、收缩温度低的缺点，同时具有优良的复鞣效果，是一种新型的多功能鞣剂。树枝状聚合物具有特殊的支化结构和大量的端基官能团，不仅与铝离子形成大量的交联键，进入皮革内部后，与皮胶原也形成大量的交联结构，具有复鞣效果，增厚率比普通铝鞣剂提高25.10%。同时可以提高革样的撕裂强度12.69%和抗张强度11.28%，且该鞣剂特殊的性能能有效地分散纤维束，使皮革表面丰满柔软。最新第四代高分子材料-高性价比树枝状聚合物材料的专业制造商—威海晨源分子新材料有限公司
Carboxyl terminated dendrimer based aluminum tanning agent without chrome.
As people’s awareness of environmental protection, negative effects of chrome tanning can’t be ignored any more, therefore, the production of little chrome, no chrome tanning agents is more important for industry. Carboxyl terminated dendritic tanning agents overcome aluminum tanning agent disadvantages that not washable, low shrinkage temperature, and have great retanning effect, is a new kind of multi-tanning agent. Dendritic polymers have hyperbranched structures and lots of end groups, can form crosslinks with aluminum and dermomyotome with retanning effect, increasing thick rate was increased by 25.10% than ordinary aluminum tanning agent. While the leather tear strength was improved 12.69% and tensile strength 11.28%, and the specific performance of tanning agents can effectively disperse the fiber bundle, so that leather surface was full soft. Weihai CY Dendrimer Technology Co., Ltd.-Professional Manufacturer for low cost dendritic polymers. -The newest 4th class polymers.
