Preferably, on described heavy ion microporous membrane, the hole density of micropore is 1 × 10
4~ 1 × 10
9individual/cm
2.
Preferably, described heavy ion microporous fenestra thickness is 5 ~ 80 μm.
Preferably, the micropore canals of described heavy ion microporous fenestra comprises: single tapering passage, biconial duct and cylindrical bore.
Preferably, the channel diameter in duct, described single tapering passage the narrowest place is 0.1 ~ 20 μm, and the channel diameter in the widest part duct is 0.2 ~ 40 μm.
Preferably, in the middle of biconial duct, the channel diameter in duct, the narrowest place is 0.1 ~ 20 μm, and the channel diameter being in the widest part duct on film surface is 0.2 ~ 40 μm.
Preferably, described lining form comprises: CA cellulose membrane, N6 film, N66 film, PP film, PAN film and PVC film.
Preferably, be fitted and connected described in as gluing being fitted and connected is fitted and connected with hot pressing.
The beneficial effects of the utility model are:
The utility model solves low, the cracky of intensity that heavy ion filter membrane exists, the problem that deflection is poor, easily Texturized, because two class films are just laminating before being cut, so the heavy ion microporous membrane of sandwich construction described in the utility model can the realize technique such as automation cuts, folds, assembling, greatly enhance productivity, saved cost.
