▎ 摘　　要

NOVELTY - Endometrial tubular nanoelectrothermal membrane fluid comprises 30-40 pts. wt. tin tetrachloride, 5-10 pts. wt. antimony trichloride, 1-5 pts. wt. graphene, 35-48 pts. wt. anhydrous ethanol and 5-10 pts. wt. cobalt chloride. USE - Endometrial tubular nanoelectrothermal membrane fluid used for preparing electric heating tube (claimed). ADVANTAGE - The fluid has high electric film heat transfer, 98% or more thermal efficiency and more than 20,000 hours service life, and saves energy from source and reduces heating tubes number and maintenance costs. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of endometrial tubular nanoelectrothermal membrane fluid comprising dissolving solid tin tetrachloride, antimony trichloride, graphene and cobalt chloride, respectively, with absolute ethanol; and mixing tin tetrachloride solution at 40 degrees C, adding antimony trichloride solution, graphene solution and cobalt chloride solution, and stirring.
