Hydroxypropyl Methyl Cellulose Fermented

Hydroxypropyl methylcellulose is used as raw material to produce oil, which can complete the use of sugar, improve the utilization rate of raw materials, reduce the residual amount of substrate in the fermentation broth, reduce the cost of wastewater treatment, and make the characteristic formula of hydroxypropyl methylcellulose beneficial It is useful for optimizing batch, batch and continuous fermentation processes, preventing the manipulation of tissue and dilution culture related problems; also beneficial for the manipulation of fermentation processes.

Hydroxypropyl methylcellulose, raw cellulose, it can be refined cotton, or it can be wood pulp. It needs to be pulverized before or during alkalization. It is necessary to pulverize the cellulose raw material by mechanical energy in order to reduce the crystallinity and polymerization degree, increase its surface area, and then improve the trihydroxyl degree and chemical reaction ability of the reactant on the glucose ring of the cellulose polymer.

Although the synthesis of hydroxypropyl methylcellulose is not complicated, the alkali, raw materials are pulverized and alkalized. Etherification, solvent recovery, centrifugal separation, washing and drying in various environments, but involves many key technologies and rich content knowledge. For different varieties of products, each environment has the latest control conditions, such as temperature, time, pressure and flow control auxiliary facilities and control instruments are the guarantee of stable product quality, reliable production system, and favorable.

Since the performance of hydroxypropyl methylcellulose is similar to that of other water-soluble ethers, it can be used as a film-forming agent, thickener, emulsifier and stabilizer in latex paints and water-soluble resin coating compositions, abrasion resistance, Uniform coating and adhesion, and improved surface tension, stability to acids and bases, and compatibility with metallic pigments. Hydroxypropyl methylcellulose has a good effect as a thickener for white water-based polyvinyl acetate paints. The degree of substitution of cellulose ether is improved, and the resistance to bacteria is also improved.
