Abstract

Et sementeringsmateriale for olje- og gassbrenner inneholder styren/butadien-la-teks og en kombinasjon av ikke-ioniske og anioniske overflateaktive midler for å forbedre de fysikalske egenskaper, spesielt fluidtap.An oil and gas burner cementing material contains styrene / butadiene-la-tex and a combination of nonionic and anionic surfactants to improve the physical properties, especially fluid loss.
