Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of proving installation of cellulose ether water retention property, comprise an iron hoop 1, two blocks of glass supporting plates, 1 layer of fast grade filter paper 4, 5 layers of Medium speed filter paper 5, it is circular cylinder cavity 6 that the inside of described iron hoop 1 forms an xsect, described iron hoop 1 comprises two openings, two openings are respectively the first opening 11 and the second opening 12, described iron hoop increases progressively successively along the direction internal diameter of the first opening 11 to the second opening 12, two blocks of glass supporting plates are the first glass supporting plate 2 and the second glass supporting plate 3, described first glass supporting plate 2 with described iron hoop at the first opening 11 place against covering, described second glass supporting plate 3 with described iron hoop at the second opening 12 place against covering, the Medium speed filter paper 5 that is of five storeys is padded successively between described second glass supporting plate 3 and described iron hoop 1, 1 layer of fast grade filter paper 4.
The internal diameter of described iron hoop at the first opening 11 place and described iron hoop are 7:8 at the ratio of the internal diameter at the second opening 12 place.
Described iron hoop is 7cm at the internal diameter at the first opening 11 place, and described iron hoop is 8cm at the internal diameter at the second opening 12 place.
The thickness of described iron hoop 1 is 5mm.
The length of side of described first glass supporting plate 2 is 15-20cm.
