What is the function of methylcellulose?

Methylcellulose is a white chemical substance, usually white powder in appearance. This substance has thermal gelling properties, that is, it will form a gel when heated and melt when cooled. Because of this characteristic, methylcellulose has a wide range of uses. For example, it can be used as an emulsifier and is also a very good thickener. Its main functions are as follows.

Functions of methylcellulose:

Use 1

This product is widely used in the construction industry. Such as a mixture of cement, mortar, joint putty, etc. It is used as a binder for film-forming agents in the cosmetics, pharmaceutical and food industries, and is also used as a sizing agent for textile printing and dyeing, a synthetic resin dispersant, a coating film-forming agent and a thickener. Methyl cellulose is a very stable substance that is resistant to the effects of acids, alkalis, microorganisms, heat, etc. In the human body, it is excreted without changing at all.

Use 2

Used as synthetic resin dispersant, coating film former, thickener, building material adhesive, textile printing and dyeing sizing agent, film former in pharmaceutical and food industries, etc.

Use three

Thickener; stabilizer; emulsifier; excipient; dispersant; adhesive; film former; hydrosol substitute. It is also used in mayonnaise, shortening, and certain other foods. Because this product is not digested in the body, it can retain several times the water, creating a feeling of fullness. It can be used to make therapeutic foods such as soda crackers and waffles. When using, first moisten the powder with about 1/5 of the required amount of hot water, then add cold water (ice if necessary) and stir evenly. EEC: Approved for use in frozen foam products, potato chips, soft drinks, special dietary foods, bakery fillings, foam toppings, sauces, and condiments.

Use four

Emulsifier in painting mediums. The process of making Tempera medium: 1. Take 31 grams of methyl cellulose, add 2.2 liters of clean water, stir and dissolve it before use, or use a volume ratio of cellulose to water of 1:25. For specific dissolution methods, refer to the above. 2. One part of methylcellulose solution plus half part of Damar varnish, half part of linseed oil and one part of water can be made into oily methylcellulose emulsion. A very important point is that the half part of linseed oil should preferably be sun-thick linseed oil, walnut oil is also acceptable. Choosing a thick oil may increase the chances of medium synthesis. Pay attention to the mixing order. Pour the oil first, then the glue and then the water. The result is an oil-water structure. After pouring the oil and glue, be sure to shake them thoroughly before adding water. After adding the water, you also need to shake them quickly to mix. A long, sealable bottle may be used as a mixing container. (It should be noted that methyl cellulose is easily salted out, so the material should be kept pure and the solution should be used as soon as possible after it is dissolved to avoid a decrease in viscosity.) Media detection method: Mix an appropriate amount of medium and color powder, grind for a while, and if water droplets precipitate, it means failure.
