There is an oil called "Wanjin Oil" and a substance called "hydroxypropyl methylcellulose." One would ask why there is no connection between the two. Hey hey, actually I want to say that the reason why it is called Wanjin Oil is because it has a wide range of uses, and I quote the reason is to explain the use of hydroxypropyl methyl cellulose is super wide! Then I will give you a description of its specific industrial use! Use one, used in the construction industry. Hydroxypropyl methyl cellulose (HPMC) is favored by the construction industry because it can not only retain water and retard the setting of cement mortar, but also as an adhesive for mortar and gypsum. Use two, used in ceramic manufacturing industry. In this industry, hydroxypropyl methyl cellulose also acts as "adhesive". Three, used in the paint industry. The thickeners, dispersants and stabilizers needed in the paint industry are all used with hydroxypropyl methyl cellulose (HPMC). What's more, HPMC can also be used as a paint remover because of its good compatibility in water or in organic solvents. In addition to the above uses, hydroxypropyl methyl cellulose has many other uses, such as: pharmaceutical industry, ink printing industry and so on. Interested friends can study it yourself.
