The technological process of die steel H13 was inguired by low temperature salt-bath vanadium-nitrocarburizing,and microstructures,hardness,element distribution and phases of the infiltration of samples were investigated.
探讨了H13模具钢的低温盐浴氮碳钒共渗工艺,并对渗层组织、硬度、渗层中的元素分布以及物相组成等进行了研究。
Only when the miscibility ofpolymers is better,a blended UF membrane with greatly improved flux orretention rate will be obtained by raising coagulating temperature or byadding a small amount of NaCl without excessive damage of other prope-rties.
虽然凝胶浴温提高都使膜的透水率提高而截留率下降,但相容性好可在截留率下降较小的情况下较大地提高透水率;利用少量NaCl 对凝胶浴的添加,也只有在相容性好时才能在不降低透水率的情况下有效改善截留率;蒸发时间的影响也因相容性不同而异,但延长蒸发时间并不可取。
