Abstract: Objective: To observe the application effect of hydroxypropyl methylcellulose on corneal endothelial protection in cataract phacoemulsification. Methods: A retrospective analysis was performed on 1262 cases of phacoemulsification and intraocular lens implantation in our hospital from April
READ MOREAbstract: Hydroxypropyl methylcellulose is a non-toxic, odorless, white or Class white powder. In the pharmaceutical industry, it is mainly used as a rate-controlling polymer material for coating materials, film materials, and sustained-release preparations. It can also be used as a stabilizer, susp
READ MOREAbstract: Using the domestic NDJ-1 rotational viscometer and the American Brooktield (LVDV-I+) viscometer, the viscosity test method of hydroxypropyl methylcellulose with a viscosity greater than 105mPa·s was studied, and the comparative viscosity test was carried out. The results show that for HPMC
READ MOREAbstract: Two kinds of coatings were prepared by using hydroxypropyl methylcellulose and hydroxyethyl cellulose as thickeners in zinc-chrome coatings, and compared them through experiments. The test results show that under the condition of the same coating quality, using hydroxypropyl methylcellulos
READ MOREAbstract: The enteric drug excipient hydroxypropylmethylcellulose trimellitate (HPMCT) was synthesized. Characterized by infrared spectroscopy, ultraviolet spectrophotometry and high performance liquid chromatography, the solubility characteristics of HPMCT in organic solvents, pH sensitivity and so
READ MOREResumen: Cuando el mismo grupo se reemplaza por el mismo grupo, el rendimiento del éter de fibrina se ve afectado principalmente por la viscosidad. Este artículo estudia los efectos de HPMC con diferente viscosidad en el desempeño del concreto. Los resultados muestran que cuanto mayor es la viscosid
