The instant hydroxypropyl methylcellulose ether is designed for water-based products. The surface of the hydroxypropyl methylcellulose ether is treated with glyoxal under a certain temperature and pH value. The hydroxypropyl methyl cellulose ether treated in this way is only dispersed in neutral cold water without swelling and viscosity, which plays a role in delaying swelling. At this time, the aqueous solution is stirred for 5-10 minutes or the When the solution environment (PH value) is adjusted to be alkaline, hydroxypropyl methylcellulose ether begins to swell and generate viscosity. This surface-treated type is usually referred to as an instant type.
The characteristic of instant hydroxypropyl methylcellulose is that when it encounters cold water, it will quickly diffuse in cold water, but it takes time for its viscosity to rise, because it only diffuses in water in the early stage, and it does not dissolve in a substantial sense. Its viscosity reaches the maximum value for about 20 minutes or more. The advantage of this is that it is used in a specific industry without dry powder mixing, or when it needs to be dissolved and hot water cannot be used due to equipment conditions and other reasons. Instant hydroxypropyl methylcellulose solves such a problem.
Instant-type hydroxypropyl methylcellulose disperses quickly in water (dispersion degree is 100%), dissolves quickly, does not clumping, especially in the later stage, the colloidal solution has high transparency (up to 95%) and large consistency, which solves the problems in practical applications. Constraints, expanding the field of application, such as the application in construction glue, the application in compound liquid admixtures, and special fields such as daily chemical washing.
We have introduced the world’s advanced production equipment and technology, have a modern production line of cellulose ether and redispersible latex powder, and ensure to provide users with satisfactory products with its strict quality control system, testing system and perfect on-site service. Now the leading products are hydroxypropyl methylcellulose HPMC, hydroxyethyl cellulose HEC, hydroxypropyl starch ether HPS, redispersible latex powder series. The products are widely used in construction, chemical industry, paint, daily chemical industry, military industry and other fields, and are respectively made into film-forming agents, adhesives, dispersants, stabilizers, thickeners, etc.
Relying on its own product quality and its status and influence in the dry powder building material additive industry, and under the premise of always maintaining the corporate mission of quality first, it is now cooperating with international and domestic well-known manufacturers for complementary products. Supporting operations: polypropylene fiber, Wood fiber, modified starch ether, polyvinyl alcohol powder, powder defoamer, water reducer, water repellent, calcium formate and other dry powder additives.
