Quality of hydroxypropyl methyl cellulose1. water solubility and thickening ability of hydroxypropyl methyl cellulose.2. Soluble in organic solvents, due to the presence of a certain amount of hydrophobic methoxyl, this product can be soluble in organic solvents, but also can be soluble in water core organic mixed solvents.3. Salt resistance: Since this product is a non-ionic and non-polymeric electrolyte, it is relatively stable in the aqueous s…

1, what are the main uses of hydroxypropyl methyl cellulose (HPMC)?Answer: HPMC is widely used in building materials, coatings, synthetic resins, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries. HPMC can be divided into building level, food grade and pharmaceutical grade. At present, most of the domestic building-grade, in the building-grade, putty powder consumption is very large, about 90% is used for put…

Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether made from natural polymer cellulose by a series of chemical processing. They are an odorless, odorless, nontoxic white powder that swells in cold water to form a clear or slightly turbid colloid solution. It has the characteristics of thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gel, surface activity, water retention and protective co…

HPMC is hydroxypropyl methyl cellulose.Hydroxypropyl methyl cellulose is also called hydroxypropyl methyl cellulose; cellulose hydroxypropyl methyl ether; Hypromellose, Cellulose. This product uses highly pure cotton cellulose as raw material and is prepared by special etherification under alkaline conditions. The whole process is completed under automatic monitoring, without any animal organs and oils and other active ingredients. This product i…

When the solution of Hebei cellulose is in low temperature, there is a hydrogen bond effect between hydrophilic groups on macromolecules and water molecules, which forms a cage-like configuration for water molecules. The heat applied at elevated temperatures will crack the hydrogen bonds between water molecules and hydroxypropyl methyl cellulose molecules, destroy the cage-like supramolecular configurations, release water molecules from the bindi…

HPMC has always known a lot. Today, I want to introduce some information about water resistant HPMC.Measures to prevent water HPMC from yellowing:1, seal the bottom with seal agent. Old wall decoration, waterproof HPMC low-grade ordinary HPMC before scraping water-proof powdering, high water-proof hpmc, should be done before the use of technical treatment, the method is: first wall spray wetting, with a spade will be old hpmc, paint all eradicate…

Q: how does the putty bubble and hollowing happen? How should we handle it?Answer: Putty layer is empty and bubbly, the main reason is that there is gas between the base layer and the putty layer, and why the air does not diffuse to the surface layer and to the base layer according to the normal internal diffusion, and appear in the middle, the main reasons are as follows: improper treatment of the base layer, so that the putty layer and the base…

1. Improve bonding strength and cohesion.It is necessary to add redispersible latex powder in cement dry mortar products. It is very obvious to improve the bonding strength and cohesion of materials. This is due to the penetration of polymer particles into the pores and capillaries of cement matrix and the formation of good cohesive strength after hydration of cement. Moreover, due to the excellent adhesion of polymer resin itself, the adhesive f…

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…

It has been reported that Foxconn is developing and using mechanical arms to replace manual labor. Its announced plan is to increase more than 10 thousand robots and 100 thousand sets of automation equipment each year. This is quite a huge project, even for enterprises like Foxconn. So, instead of asking why Foxconn has invested so much in robotics, we just wonder if this will lead more manufacturers to fabricate robots instead of human labor, ca…
