A novel pressure-sensitive adhesive containing carboxymethyl starch (CMS) with various degrees of substitution, has been developed for the paper industry. Obtained adhesives were transferred onto water-dispersible carrier giving repulpable double-sided splicing tape. The effect degree substitution (DS) on essential properties: tack, peel adhesion, as well shear strength steel and papers have te...

Inflow control devices (ICD), which prevent water breakthrough by controlling the inflow profile of a well, have been used successfully in many oilfields. This paper will introduce a new discovery and an unsuccessful example. Moreover, this paper investigates meticulously and thoroughly to find the application conditions of the new discovery. Based on permeability rush coefficient and permeabil...
