The level of polymerization of polyethyleneimine used in the paper sector is around 100. Polyethyleneimine has high reactivity, can respond with hydroxyl teams in cellulose and also cross-link polymerization, to ensure that the paper has wet stamina. The existence of any acid, alkali and also light weight aluminum sulfate will affect its damp toughness and also retention. Utilized as a damp stamina representative for unsized breathable paper, a retention help as well as a beating representative in the papermaking process, it can reduce the whipping level of the pulp, improve the dewatering capability of the paper, accelerate the pulp water drainage, and also make the penalty fibers in the white water very easy to flocculate.
PEI and also its by-products are used for elimination of flocculants, heavy metal adsorbents and also surfactants in water treatment as well as gas filtration;
In the paper industry, it is used as a supporting synergist as well as a water drainage accelerator;
In the fiber sector, it is utilized as a damp toughness representative, antistatic therapy, flame resistant processing, contraction resistance, coloring enhancement, etc;.
Used in finishings, inks, and adhesives (including thermal welding and also plastic securing), it can advertise bond, creep resistance, boost pigment as well as filler diffusion, stop aggregation, as well as boost covering security, etc;.
Utilized in cosmetics to boost hair quality, anti-bacterial and soft skin;.
In oil extraction and deep well procedures, it can stop fluid loss, minimize viscosity, protect against paraffin deposition, as well as enhance clay security;.
It can be used in the medical and pharmaceutical fields to boost the compatibility of synthetic organs as well as blood, and also it can additionally be utilized as a finish for medical tools;.
Furthermore, it is additionally a component of ion exchange resin as well as exchange membrane, material crosslinking agent, formation help, electroplating gloss representative, steel rust prevention, gasoline and also gasoline accelerant, lubing oil additive, glass cleaner, liquid chromatography stationary phase, Polymer stimulants, and so on, are likewise used in the study of synthase models.
