查询词典 chromium

With only 2% chromium powder, the nano-composite tanning agent can thicken the leather by 124.5%, the shrinkage temperature reaches to 95 DEG C.; compared with a chrome tanned leather, a leather tanned by the nano-composite tanning agent has a tensile strength, peeling strength and elongation at break improved by 51.8%, 8.2% and 13.3% respectively, has no obvious stratification or sedimentation during over 12 months of storage period.

所述复合鞣剂只需配入2％的铬粉，就可使皮革增厚高达124.5％，收缩温度达到95℃以上；其鞣革相较于铬鞣革，革的抗张、撕裂强度分别提高了51.8％和8.2％，断裂伸长率也提高了13.3％，存放期12个月以上无明显分层和沉淀。

Its synthesis and structure,its interaction with collagen and chromium complexes,as well as its effect on chrome tanning properties,have been studied.

主要研究了该改性剂的合成条件、结构、与胶原和铬配合物的相互作用以及用于改性后对胶原铬鞣性能的影响。

Collagen has been treated with DHTPA and then tanned with chromium complexes,and the effect of DHTPA on chrome tanning properties has been investigated by determining the chrome absorptivity and fixation as well as the physical properties of the crust.

用DHTPA对胶原改性后进行铬鞣，通过铬的吸收率、铬的固定率、坯革物理机械性能等指标的测定，研究了DHTPA对胶原铬鞣性能的影响。

Because of the enhancement in chromium absorptivity and fixation,the dosage of normal chrome powder can be reduced from 6%to 4%in conventional process,and can be reduced from 6%to 3%in two-stage chrome tanning process,and thus the chrome absorptivity and fixation can be enhanced further.

两步铬鞣时可将标准铬粉的用量由传统的6%减少到3%，这时铬的吸收率和固定率还会进一步提高。
