Problems solved by technology

The formulas of solutions added by different manufacturers are different, resulting in product differences
[0003] Existing NC membranes for test papers are all extruded to dissolve the slurry and press it into a thin film, but the finished product materials are mostly used in conjunction with other molecular materials , the folding of the film during installation will easily lead to damage to the finished product, and there is no uniform fixing mechanism inside, which makes the composition of the extrusion solution uneven, and the use effect is poor after drying. The existing NC film needs to increase the water absorption of the NC film , adding an active agent during the fusion process increases the hydrophilic effect of the NC membrane, but the effect of the active agent becomes worse in a relatively dry environment, and the fusion with the membrane body is weak when added from the outside. The existing NC membrane does not have a long-lasting use time. When the adsorption of water reaches the maximum value, the material becomes soft and the use time is reduced

Abstract

The invention discloses an NC membrane for high polymer material test paper, and the NC membrane comprises a first paper sleeve, the top of the first paper sleeve is provided with a fixing mechanism, the bottom of the first paper sleeve is provided with a water absorption mechanism, and the bottom of the inner wall of the first paper sleeve is respectively provided with a water distribution mechanism and an adsorption mechanism, so that the dissolved pulp component distribution is more uniform, the thickness of a membrane body is increased through the effect of a fixed paper frame, the membrane body is not prone to damage when being installed with other structures in the later period, dissolved pulp is evenly distributed, the use quality of the NC membrane is improved, a water outlet groove between the membrane body and the fixed paper frame enables liquid permeated by the dried polymer dissolved pulp to enter a water absorption structure at the bottom through the water outlet groove, an active agent acts on the dried polymer dissolved pulp, so that the material of the polymer dissolved pulp is fully absorbed, the hydrophilicity of the NC membrane in use is improved, the adsorption of the water absorption mechanism on redundant wastewater is improved through dispersion holes in a water absorption layer plate, and the service time of the device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to an NC film for polymer material detection test paper. Background technique [0002] The raw material nitrocellulose particles are a very common organic chemical, which is dissolved to form a mixed slurry. In the slurry, the properties of the final film are adjusted by adding a certain proportion of reagents. Generally, it mainly contains surfactants / polymers In a buffer system in which substances / salt ions / forming agents, etc. are dissolved. The formulas of solutions added by different manufacturers are different, resulting in product differences. [0003] Existing NC membranes for test papers are all extruded to melt the slurry and press it into a thin film. However, the finished material is mostly used in conjunction with other molecular materials. Folding of the membrane during installation will easily lead to damage to the finished product, and there is no The uni...
