全苏道路科学院列宁格勒分院最近研究了新的阴离子型ПАВ,它是木材化学工业自身的产品:塔油沥青熔胶(OCT81—12—77)和松脂沥青(标号CA),是空气吸附(Воздуховопекающий)掺加剂CHB(TY81—05—75)中和的一种物质。 塔油沥青熔胶(皂化了的塔油)——是从褐色的到黑褐色的固体材料。它含有达25％的钠盐(皂)树脂和脂肪酸及中性物质,达35％的非皂化物质和小于9％的水。环—球法的软化点不低于70℃,它能很好地溶于水中。 松脂烃沥青—是黑色—褐色的固体材料,含有不小于95％的皂化树脂和脂肪酸,以及不大于5％的水。环—球法的软化点不低于90℃,很好地溶解于水。 含有这种ЛAB制造的石油沥青乳液,沥青标号由БНД40/60到БНД130/200(ГОСТ22245—76),石油沥青与页岩沥青(标号БСД250/300,БСД190/250(РСТЭССР82—79))混合的乳液,以及页岩沥青(25℃的针入度为130)和石油重油(粘度C_(60)~5=300秒)混合的乳液。(以不同的结合比例制造了混合料)。
The Leningrad branch of the All-Su Road Academy of Sciences recently studied the new anionic type, ПАВ, which is the product of the wood chemistry industry itself: TAPA (OCT 81-12-77) and Rosin Asphalt (CA) Воздуховопекающий) A substance that is neutralized by the additive CHB (TY81-05-75). Tower oil pitch (saponified tower oil) - is a solid material from brown to dark brown. It contains up to 25% sodium salt (soap) resin and fatty acids and neutrals up to 35% non-saponified material and less than 9% water. Ring - ball method softening point of not less than 70 ℃, it can be well dissolved in water. Turpentine Bitumen - a black-brown solid material containing not less than 95% saponified resin and fatty acid, and not more than 5% water. Ring - ball method softening point of not less than 90 ℃, well dissolved in water. The oil bitumen emulsion containing such ЛAB was blended with an emulsion of a bitumen grade marketed as БНД 40/60 to БНД 130/200 (ГОСТ 22245-76), a mixture of petroleum pitch and shale pitch (designation БСД 250/300, БСД 190/0/250 (РСТЭССР 82-79) , As well as emulsions of shale pitch (penetration at 25 ° C: 130) and heavy petroleum oil (viscosity C_ (60) ~5 = 300 sec). (Mixes are made in different combinations).
