The present disclosure relates to a polyethylene having high degree of crosslinking and a crosslinked polyethylene pipe including the same. The polyethylene according to the present disclosure has a high content of ultra-high molecular weight, and thus a crosslinking rate is improved, and thus a sufficient degree of crosslinking is exhibited even when the crosslinking time is shortened, thereby exhibiting excellent strength and pressure resistance characteristics.

Polyethylene having high degree of crosslinking and crosslinked polyethylene pipe comprising the same

The present invention has a special filling (WIE) property parameter value developed using microrheology technology, and thus exhibits improved high viscoelasticity flow properties, has low mobility when injected into skin whilst still maintaining the shape thereof, and thus has excellent soft tissue restoration properties, for example for the cheeks, breasts, nose, lips or bottom, and excellent volume expansion and wrinkle alleviation properties.

Filler comprising hyaluronic acid hydrogel having excellent filling properties

The present disclosure relates to a crosslinked polyethylene pipe having excellent physical properties. The crosslinked polyethylene pipe according to the present disclosure has optimized the degree of crosslinking and storage modulus by finding out the optimum physical property range between the degree of crosslinking and the storage modulus which have a mutual trade-off relationship, whereby the crosslinked polyethylene pipe according to the present disclosure has excellent long-term durability and short-term pressure resistance, and thus can be applied to various fields requiring these physical properties.

Crosslinked polyethylene pipe having excellent physical properties

The present invention relates to a big data-based battery inspection method. Specifically, the present invention is for providing a big data-based battery inspection method which applies information on a metal part of a battery measured by an eddy current sensor to a discrimination function so as to quickly inspect the state of the metal part.

The present invention relates to a method of deriving significant factors of rheological properties, which influence folding stability for developing an adhesive with excellent folding stability, and predicting folding stability through the same. It is possible to select an adhesive with excellent folding stability by measuring initial stress and a strain recovery rate as the significant factors, and measuring predicted folding stability (predicted number of times of folding) therefrom.

Method for selecting adhesive with excellent folding stability

A method for predicting the likelihood of coagulation of active material particles contained in a slurry for electrode preparation includes measuring rheological properties before and after the slurry is subjected to a shear. The estimation method enables a prediction of filter clogging with a slurry, and thus makes it possible to estimate the likelihood of filter clogging with a slurry without passing the slurry directly through the filter, thereby improving the efficiency of a battery manufacturing process.
