1. the preparation method that in blood products, FII precipitates, it is to take blood plasma as raw material, utilize cold ethanol method to prepare successively FI+II+III precipitation, FI+III supernatant, get again FI+III supernatant through the separated FII of cold ethanol method, press filtration, gets precipitation and get final product, and it is characterized in that:

  • in the pressure-filtering process after separated FII, use PALL50 filter plate, the consumption of filter plate is 5~

    10m 2/ 1000L;

    Employing diatomite is flocculating aids, and precoated layer diatomite used is 80-95g/m 2filter plate, treats that in filtrate, diatomaceous consumption is 0.2~

    0.3g/L blood plasma;

    In described diatomite, SiO 2content is 96.0~

    98.7%, Al 2o 3content is 0.6~

    1.2%, Fe 2o 3content is 0.3~

    0.4%, and acid-soluble material matter content is 0.05~

    0.12%, and water-soluble substances content is 0.15~

    0.20%.
