  • What is nonionic polyacrylamide (NPAM) gel?
  • Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.
  • Can phenolic resin cross-linked NPAM gel be used for water production control?
  • Conclusions In this work, a phenolic resin cross-linked NPAM gel was selected as an in-depth profile control agent for water production control. The gelation time and gel strength of the NPAM gel can be controlled by adjusting the NAPM polymer or cross-linker concentration.
  • What is a polyacrylamide gel made of?
  • The polyacrylamide gel is made of the monomer acrylamide, the crosslinker N,N’-methylene bis-acrylamide, the accelerator N,N,N’,N’-tetramethylethylenediamine (TEMED) and the free radical generator APS. Gel buffer solutions must be stacked and resolved to separate NCs as they move through the porous gel when an applied potential is present.
  • What happens when polyacrylamide and bis-acrylamide crosslink?
  • By crosslinking polyacrylamide and bis-acrylamide, a network of pores is formed in the gel. Due to the pore size, molecules can be sorted via the gel matrix. Gel pore size depends on the concentration of monomers (% T).
